Abstract: A flow rate sensor has a problem that a resistance value of a heat generating resistor itself varies and sensor characteristics are changed during use of the sensor for a long term. Also the temperature of the heat generating resistor must be adjusted on a circuit substrate with a resistance constituting one side of a fixed temperature difference control circuit, and this has been one of factors pushing up the production cost. All resistances used for fixed temperature difference control are formed on the same substrate as temperature sensitive resistors of the same material. This enables all the resistances for the fixed temperature difference control to be exposed to the same environmental conditions. Hence, even when the resistances change over time, the changes over time occur substantially at the same tendency. Since the resistances for the fixed temperature difference control change over time essentially at the same rate, a resulting output error is very small.

Abstract: A mask mark is irradiated by an ultra-violet light source, thereby the image of the mark is passed through a lens and a half-mirror, then reflected by a mirror, thereafter further passed through a beam splitter and a lens, forming an image on a CCD.

Abstract: Acoustic volume indicators comprise a resonator, a frequency detector, and an indicator. The resonator can be an impactor or a vibration generator. The detector responds to vibration signals provided from the tank wall, which signals will show a significant increase in amplitude at the resonant frequency of the tank and its contents. The detector can be an accelerometer designed to record the received signal. The recorded signal is converted/analyzed by the frequency detector, and is compared to a known preprogrammed specific frequency vs. volume characteristic of the tank. Various audible and/or visual output or indicator devices can be used to indicate whether the liquid volume measurements within or outside of a predetermined volume range based on the known tank characteristics.

Abstract: A unit connecting mechanism and box-like unit is disclosed having an engaging unit (4) and a connecting pin (3) which are mounted to the box-like unit (1) to allow a plurality of box-like units (1,1) to be coupled to one another in a vertical direction. A handle (44) is operatively connected to a hook (43) to catch an engaging rod (3a) and is vertically raised to cause a stopper (45) to lock the hook (43) and the engaging rod (3a) in a locked condition, with operation of the handle (44) causing the stopper (45) to move downward to cause the hook disengage from the engaging rod for thereby uncoupling the box-like units (1,1) from one another. As a result, the unit connecting mechanism can be manufactured in a compact structure, providing a capability for a worker to easily and appropriately perform coupling and uncoupling operations of the box-like units.

Abstract: To accomplish the above object, this embodiment forms the coil connecting parts 34e on the vertical sections 34d of the commutator segments 34b so that the coil conductors 32a may be assembled axially. On the outer circumference of the coil connecting part 34e, this can form the commutator segments 34b in a body with the lock members 34f that prevent the coil conductor 32a from going out in the centrifugal direction from the coil connecting part 34e. Therefore, the rotating strength (the centrifugal strength) of coil conductors 32a can be improved in the coil connecting part 34e without any additional member for the lock member 34f and without increasing the number of manufacturing steps pertaining to the lock member 34f.

Abstract: An injection manifold has a main runner provided with a supply inlet intermediate opposite ends of the runner. A number of branches intersect with the runner along its length so as to be disposed at unequal distances from the inlet. In order to achieve more simultaneous delivery, uniform fill rate, and identity of temperature of hot melt across all cavities of a multi-cavity set to achieve more uniform cooling of the preforms, restrictor pin assemblies are provided in association with certain of the branches to adjustably constrict the space available for melt flow from the runner into the branch. In a preferred form each restrictor pin assembly includes a pin aligned axially with the branch and passing transversely through the runner, the pin being adjustable between a fully extended, maximum constriction position in which the tip of the pin is located within the branch and a fully retracted, open position in which the tip is withdrawn out of the branch and is spaced below the opening of the branch.
