PURPOSE:To obtain a resistor, which has high resistance and characteristics thereof hardly vary due to a temperature change, by forming the thickness of a polycrystalline Si layer used as the resistor so as to satisfy specific conditions. CONSTITUTION:A diffusion region 22 having low resistance employed as a lower electrode is shaped to the main surface of a single crystal Si substrate 20, and a p...

PURPOSE:To eliminate a useless resistance in a displacement type supercharger, and to aim at enhancing the output power of an engine and the economy of fuel consumption, by providing a device which makes variable at least either one of the suction terminating time at the suction air take-in port of the displacement type supercharger driven by an engine and the discharge initiating time at the pres...

PURPOSE:To decrease the number of parts of a coordinate input device and to reduce the thickness of said input device, by arranging photocells in a 2-dimensional matrix as photosensitive elements and writing the coordinates with light. CONSTITUTION:When light is applied through a glass substrate 6, the optical electromotive force is produced among CdS sintered bodies 7 and CdTe sintered bodies 8 w...

PURPOSE:To reduce considerably the transfer amount of message by deciding whether or not a message transmission request is equal to the preceding one and transmitting only a part having different contents. CONSTITUTION:An on-line control program 3 first decides whether the transmission requests of display terminal devices 6-1-6-n are first or not. If these requests are first ones, an entire messag...

An apparatus is provided to enable a press to automatically apply an electrical connector to a printed circuit board. A locator block is secured to a floating pin holder plate which is mounted to a press ram, the connector is placed in position and partially inserted on the board and the board is secured and accurately disposed below the locator block. The locator block has a recess which surround...

PURPOSE:To make smooth acceleration securable even in time of a lane change to an overtaking lane, by installing a car speed controlling device, which controls a self-speed so as to become a safety car-to-car distance on the basis of the self-speed and the car-to-car distance detected. CONSTITUTION:An automobile is provided with a car speed sensor 9 for detecting a self-speed, a winker switch 10 f...

PURPOSE:To perform die bonding or wire bonding by providing a bonding material supply head, by providing a component fitting head and a wire bonding head on an X-Y table, by collating a pick-up output of a TV camera with a standard to correct deviations, and by conduct switching automatically according to the correction. CONSTITUTION:A position to which a component is fitted is detected automatica...

A glass element (10) useful for accurately positioning one or a series of optical fibers for interconnection with other fibers or active optical transmitter or receiver elements, comprises an accurately positioned grooved surface relief pattern achieved by differential densification of a photosensitively opacifiable glass.

Measuring apparatus for determining the position of a point in a measuring volume relative to a datum point at which three mutually perpendicular axes intersect, includes a probe member supported for movement within that volume. Errors due to rotations about the various axes are corrected by providing additional transducers on each axis, there being (n+1) transducers where n is the number of rotat...

PURPOSE:To attain an easy remote fault diagnosis by connecting on a serial line a display part and a key input part of an NC device. CONSTITUTION:An IOC2 is connected serially to a CRT control CPU10, and a CRT3 and a keyboard 4 are connected to the CPU10. In a remote diagnosis mode a changeover switch 12 of an NC device is first switched to the side of an acoustic coupler 13. Then the transfer spe...

PURPOSE:To attain the continuous confirmation of the numerical control data with a mobile body kept in a stop mode, by ignoring a specific command code to perform the numerical control processing based on the numerical control data in a confirmed operation mode. CONSTITUTION:When the numerical control data of a single unit is read out by a data reading means 2, a specific code identification means...

PURPOSE:To reduce the follow-up error and mechanical vibrations of a servo system in a relevant section by calculating the speed unit vector of a route of robot movement at a bent or corner part and multiplying said unit vector by a proper speed coefficient. CONSTITUTION:If the speed of a work 2 is set at V1 at a corner part, a controller 4 calculates the speed unit vector on a route at a working ...

PURPOSE:To attain correction of a route on a free surface over a cubic space by calculating the position of a torch on a plane at a teaching point from the posture of the torch and just giving the value of a correction amount through an operator. CONSTITUTION:At the outset the tangential direction vector is obtained for a route at a teaching point from an equation of a free line passing through a ...
