Abstract: The invention relates to forming, on a piezoelectric element, a plurality of piezoelectric walls and concave grooves so as to be arranged alternately and parallel to each other. Thereafter, a conductive layer of a metallic thin film is formed on the back end surface and the bottom surface opposite to the grooved side of the actuator board, side surfaces of the piezoelectric walls, and the electrodes are conductably connected with the conductive layer. Then, the actuator board is subjected to a dicing process or the like to form a plurality of dividing lateral grooves on a back end surface and a bottom surface of the actuator board, forming a plurality of divided conductive patterns extending in the front and rear direction of the actuator board, and additionally, to form a dividing longitudinal groove intersecting with the lateral grooves on the bottom surface, separating the conductive patterns from other portions of the conductive layer.
Abstract: An insert molding method and apparatus not requiring a multiple movable molds and permitting stable insert molding to be performed by means of light, small-sized equipment. A robot for removing a molded product and a robot for placing an insert member are arranged around a mold clamping mechanism, and making them perform removal of a molded product and placement of the insert member, respectively, during a mold opening process of a molding cycle. The molding apparatus does not requirs a plurality of lower molds (stationary molds) and accordingly permits to eliminate a turntable or a sliding table, whereby the molding apparatus can be reduced in size and weight. Further, since only one lower mold suffices to obtain one type of molded products, the manufacturing cost of molds can be reduced and the mold temperature control can be made easier, so that not only the molding conditions are stabilized but also the life of the mold can be prolonged by eliminating the poor positioning.
Abstract: An electric injection molding machine having a high degree of freedom in design, in which the design change of a part of the injection molding machine does not influence the whole design of the machine. The various layouts can be selected in accordance with a space in a factory in which the machine is to be installed. A base for a mechanical component and a housing for an electric component are provided separately and independently. A clamping unit and an injection unit of the mechanical component is mounted on the base. A power unit for supplying the mechanical component with electric power and a control unit for controlling the mechanical component of the electric component are accommodated in the housing. The mechanical component and the electric component are combined to constitute the injection molding machine in accordance with various arrangement patterns.
Abstract: Principal parts of an injection molding machine (1) are formed by joining a stationary platen (3), moving platen (4), mold clamping mechanism section (7), and rear platen (5) in the order named, the stationary platen (3) and the rear platen (5) are connected by means of tie bars (2), and the moving platen (4) is actuated by means of the mold clamping mechanism section (7) that is provided between the rear platen (5) and the moving platen (4). Guide rods (9) are arranged protruding from that surface of the moving platen (4) which is opposite from the surface on which a stationary-side is mounted, whereby a crosshead (10) is guided in sliding motion. Further, the guide rods (9) are caused to penetrate and project from the rear platen (5), and an injection unit (8) is fixed to their respective distal ends. A slide guide for the crosshead (10) and a support guide for the injection unit (8) are formed integrally with each other, whereby the number of components used and the manufacturing cost are reduced.
Abstract: A zero point adjusting method and apparatus for a pressure detector of an injection molding machine, capable of carrying out a zero point adjustment of the pressure detector when external loads acting on the pressure detector are completely removed without disassembling an injection mechanism. An advance limit position Qf and a retreat limit position Qb of a screw are detected by driving the screw with a low output to determine an intermediate position Pm. By moving the screw to the intermediate position Pm, a resin reaction force acting directly on the screw is removed. Reciprocating motion in which an amplitude decreases gradually is imparted to the screw, thereby causing a backlash, having equal plays in the advance and retreat directions, between a ball nut and a ball screw. Then, the zero point adjustment of the pressure detector is made.
Abstract: An automobile-installed-apparatus controller includes: a plurality of types of control-designation units having different switching functions and built-in discrimination devices with different circuit constants; unit mounts on which the plurality of types of control-designation units are capable of being mounted; and a control-designation-unit determiner in which when any one of the plurality of types of control-designation units is mounted on the unit mount, a value dependent on the circuit constant of the built-in discrimination device is detected, and the type of the mounted control-designation unit is determined based on the detected result.
Abstract: A diagnostic marker containing (a) a detection system such as an antibody and (b) a fluorescent functional group that is bound to the detection system and represented by the following formula: ##STR1## wherein R.sup.1 and R.sup.2 independently represent hydrogen atom, an alkyl group or the like; R.sup.3 represents an alkyl group, a sulfonic acid-alkyl group or the like; X.sup.- represents an anion species, if required; Y represents a C.sub.1 -C.sub.10 alkylene group or a C.sub.1 -C.sub.10 alkylene group containing one or more atoms selected from the group consisting of oxygen atom, nitrogen atom and sulfur atom. The diagnostic marker emits fluorescence having a wavelength of 780 nm or more when irradiated with near or far infrared rays, and thus useful for infrared endoscopic diagnosis or identification of a focus in surgical operation.
Abstract: The tip of a ball screw (28) is mounted so as to be rotatable with respect to a pusher plate (14) but immovable in the axial direction. A ball nut (31), which mates with the ball screw (28), is attached to a rear plate (2) through a load cell (33). Even though a force in the rotating direction is applied to the ball nut (31) through friction as the ball screw (28) rotates, the applied force never acts as a force to rotate the pusher plate (14). Thus, the level of sliding resistances between the pusher plate (14) and guide rods has nothing to do with the magnitude of the rotatory force of the ball screw, so that resin pressure components can accurately be extracted from the output of the load cell (33).
Abstract: A handling robot (13) for holding a part or a core by electrical discharge machining, and for taking a part or a core out of an electrical discharge machine is attached integrally to a front-side panel (11) of a submerged tank (9) of the machine. Thus, the handling robot (13) need not be controlled in concert with table feed for the electrical discharge machining. When the front-side panel (11) is swung open, the handling robot (13) swings to a retreating position.

Abstract: In a mold clamping apparatus of an injection molding machine using five-point double toggles, a projection (17) is formed at a side of a link (14) of which one end is connected to a rear platen (6), that side being opposite to the side facing a crosshead (18). And a pin is inserted in a through hole formed in the projection (17) and a through hole formed in the other end of a link (16) of which one end is connected to the crosshead, with these through holes being in alignment with each other.
Abstract: Over the whole range of the injection process, standard injection speeds and pressures are set and sections for injection speed control and sections for pressure control are set according to the length of time t, screw position S, or injection pressure P, each after the start of injection, or following the combination of the length of time and the screw position or of the length of time and the injection pressure. The arrival at the point of changeover from one control section to another is followed by a control mode shift. If the shift is made for speed control, injection speed is controlled in a manner such that actual injection speed may agree with one standard injection pressure, while if pressure control is selected by the shift, there is provided feedback control which is put into practice so that actual injection pressure may coincide with one standard injection pressure.
Abstract: A driving apparatus for an electrically-operated injection molding machine not requiring any bearing nor any connector. An electric motor having a rotor shaft on which a ball screw is integrally formed is mounted on one of a cross-head and a rear platen of a clamping mechanism, while a ball nut threadedly engaged with the rotor shaft is fixed to the other of the cross-head and the rear platen to constitute the driving apparatus for linearly moving the cross-head. As the ball screw is integrally formed on rotor shaft, any connector for connecting these two members is unnecessary. As the ball screw is directly rotated by the motor positioned coaxially with the ball screw, any bearing for bearing a redial force acting on the ball screw and rotor shaft. The apparatus may also be applied to an ejection mechanism, an injection mechanism and a nozzle touch mechanism of the electrically-operated injection molding machine.
Abstract: A plasticization control method for an injection molding machine in which the plasticized state of resin in an injection cylinder is controlled in measuring based on the detected rotating force of a screw. A reference screw rotating force C or F required for desired measuring operation is determined. Using the reference screw rotating force C or F as a reference, upper and lower limits D and E of an allowable screw rotating force range, in which measuring can be performed normally, are set for each of screw positions, and then stored as an allowable value file. The rotating force V acting on the screw during measuring operation is successively detected. If the rotating force V is not between the upper and lower limits D and E of the allowable range relating to the current position of the screw, it is judged that plasticization is abnormal and an abnormality alarm is outputted.
Abstract: An injection molding machine provided with an easy-to-operate and space-saving display unit, a clamping unit and an injection unit arranged laterally. The display unit is installed on an injection-side gate enclosing the injection unit. The display unit is movable as the injection-side gate is opened or closed, to simultaneously observe both the mold clamping-side gate and the display unit. Alternatively, the display unit is installed on an injection-side gate enclosing the clamping unit.
