Abstract: A multivalued ALU is composed of a multivalued signal source, a memory array, a selection array, an AND array and an output circuit. The multivalued signal source generates signals each of which represents a logic value of multivalued logic. The memory array is provided with an address line group for each and every function to be implemented, each address line group comprising a number of address lines. Which multivalued logic signals will appear on the address lines of each address line group depends upon a program based on the truth table of the corresponding function. Any one of the plural address line groups is selected by the selection array, to which a signal designating the function to be implemented is applied. One address line in the selected address line group is selected by the AND array, which has an input signal applied thereto, and the logic value signal on the selected line is delivered via the output circuit.

Abstract: A contact member supporting member is pivotably supported to a slide member which abuts on a part of an IC card to be inserted and is moved by the IC card. When the slide member moves, the supporting member also moves. The supporting member is swung in the direction of the IC card by fixed cams. Thus, contact members of the supporting member come into contact with contacts of the IC card. Since the contact member supporting member moves together with the IC card, the contact members do not slide on the surface of the IC card. Therefore, the abrasion of the contact members and the damage of the IC card which are caused by the slide friction between the contact members and the surface of the IC card, and the like can be prevented.

Abstract: According to the invention, a pair of pockets (13) are formed in one flange (12). A pair of almost L-shaped connecting terminals (14) are fitted into the pocket with a pressure. The starting and terminating sides (10a, 10b) of a coil core wire (10) are respectively wound around the connecting terminals. Thus, the cutting-out of the coil core wire is prevented and the connecting work can be easily performed.

Abstract: A microswitch in which a good snap action feeling is obtained and an operating stroke is enhanced is provided. A compession spring is interposed between a movable member and a swingable lever which are respectively pivotaly supported at close positions. The swingable lever is operated by a push button which is vertically slidable. Further, restricting plates to restrict the motion in the width direction of the movable member are attached to the push button. A positioning member to hold the swingably lever to the position which faces the push button when the microswitch is assembled is also provided.

Abstract: An electric switch system for a DC motor powered power tool, comprising: a moveable block which is adapted to be manually displaced between a first position and a second position for speed control of the motor; a fixed block arranged adjacent to the first moveable block; a manual selection lever pivotally attached to the fixed block and adapted to be manually rotated from a neutral middle position to either side for the selection of the rotational direction of the motor; a cam structure for permitting the manual rotation of the manual selection lever in either direction away from the middle neutral position only when the moveable block is at the first position and keeping the angularly displaced state of the manual selection lever when the moveable block is displaced away from the first position. Thus, the selection of the rotational direction of the motor and the speed control of the motor can be accomplished as a continuous single operation, and the convenience of the power tool is improved.

Abstract: A switch is disclosed having a movable piece with a movable contact and a movable plate coil, a fixed terminal provided with a fixed contact facing the movable contact, a movable coil spring with an end being fixed at a standing piece of a common terminal, wherein the other end of the coil spring is coupled to the end of a movable piece, and wherein the movable plate coil is biased by the movable coil spring with one end of the movable plate coil swingably held by a holding piece of the common terminal, and a push-button for pressing the upper portion of the movable coil. The switch has an actuator having a supporting member which rotatably engages with the case, wherein the supporting member is formed in a plane generally perpendicular to a rotary shaft of the actuator.

Abstract: This electric connector includes a housing formed with a single row of holes for receiving male terminals and ends of sheathed wires connected thereto, and further formed with means for, if and when two of the housings are laid together with their two single rows of holes substantially parallel, locating them with respect to mutual sliding movement. Thereby, if it is desired to provide only a single row type connector, a single one of such housings is used by itself; but, if it is desired to provide a multiple row type connector, then two or more of such housings are laid together with their single rows of holes substantially parallel, and now the locating means keeps them from undergoing mutual sliding. Optionally, the connector can further include means such as a clip for holding together these several housings.

Abstract: An electric device with an operation indicating light has a base and a case transversely divisible in a main frame and a case cover. The main frame is fitted to the base at one open end of the frame. A resin material is injected into the space provided by the base and the main frame. The case cover is fitted to the other open end of the main frame so that an operating indicating lamp can be seen through an indicating hole in the case cover. Thus, the device can be easily assembled, and the resin material does not leak from the gap between the operation indicating lamp and the indicating hole. Cracks are prevented from developing in the solder connecting the lamp to the circuit board. In addition, the lamp can be positioned at a high precision because no packing is required to prevent resin leakage.

Abstract: An apparatus for automatic inspection of printed circuit board assemblies inspects for the correct presence, positioning, and orientation of component parts mounted on a base printed circuit board by processing an image which is obtained from the base printed circuit board mounted with these component parts. In this method for inputting reference printed circuit board assembly data to such an apparatus, a reference base printed circuit board is prepared with reference component parts mounted on it in which the visual distinction between the reference base printed circuit board and these reference component parts is clear, and then an image is obtained from this reference base printed circuit board assembly, and this image is then processed in order to obtain the reference printed circuit board assembly data. Thereby laborious keying in of such reference printed circuit board assembly data is avoided, and the occurrence of errors is minimized.
