Title: Length measuring instrument
Inventor: UEDA TOSHITSUGU
IPC: G01B9/02
Filed: 1988-02-24
Abstract: PURPOSE:To obtain the length measuring instrument whose output drift due to temperature and vibration is corrected by finding the inclination of a phase difference distribution by plural photodetectors and correcting a length measured value with the previously found relation between the inclination of the phase difference distribution and a drift quantity. CONSTITUTION:Signals of the photodetectors (E-H) are outputted to a phase difference detecting device 41 and summed up and arithmetic operation, e.g. E-H and G-H among those signals are found to obtain inclination psi1 and psi2 of the phase difference. Those arithmetic results are sent out to an arithmetic unit 51 to calculate an object distance according to the sum signal and the signal from a laser light source 1. The sum signal, however, is corrected in advance by using a correction table according to the inclination psi1 and psi2 of the phase difference calculated by using the photodetectors (E-H). Consequently, the length measuring instrument whose output drift due to temperature and variation is corrected is obtained.

Title: Interface circuit
Inventor: TAKAHASHI KENICHI
IPC: G06F15/16
Filed: 1984-03-06
Abstract: PURPOSE:To improve the reliability of the whole system by comparing an input signal from a precedent device with an output signal to a trailing device. CONSTITUTION:The coincidence of a bit sequence which continues by the predetermined number of bits is detected to check invariably on the transfer of the input signal from the precedent device to the trailing device through a shift register and a series/parallel converting circuit 21. If a data transmission link 3 is disconnected owing to abnormality of a secondary station, a timer circuit 26 does not receive a coincidence detection signal (a) within a set time Ts, so the timer enters an overflow state and the relay circuit 27 of a line switching circuit 22 is operated to set relay contacts rl11 and rl12 of a line switching circuit 22 at by-pass sides. Thus, the stop of the whole system due to the fault of one slave stationis evaded.

Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To conduct the smooth production of small-sized chips by feeding a log material into a cutting means for adjusting a feeding angle of a log material by holding it with a forced log feeder provided with a sub-rotor fitted with pressure rollers and adapted to move vertically. SOLUTION: A disc 10 is rotatably driven by a motor and a conveyor 30 and a pressure roller 45A are rotatably driven by driving motors 36a, 36b. When a log material 50 is fed in a direction indicated by an arrow S from a feeding port at one end of the conveyor 30, the log material 50 passes through a forced log feeding device 40 while it is being transferred into the disc 10 direction, and when brought into contact with the passing log material 50, a pressure roller 45B moves up and down while meshing with the log material 50 to catch it and pressingly holds the log material 50 by virtue of the weight of a sub-rotor 43.  Then, the pressure roller 45A feeds the log material 50 at a constant speed when the forced log feeding device 40 moves vertically about a catching axis 40a, and the log material 50 is cut into small-sized, granulated corn-like chips with a cutting blade 13 mounted on the disc 10 at a set feeding angle. This enables smooth cutting at certain intervals to produce uniformly sized chips and low-noise and smooth operation.

Title: Passbook and certificate issuing device
Inventor: TAMAMOTO HIDEO
IPC: G06Q40/00
Filed: 1987-02-27
Abstract: PURPOSE:To make it possible to facilitate the change-over between the storage and managing processes for passbooks and certificates by providing an adjusting lever for adjusting the gap between a first gate for the passnotes and the certificates and a separation roller. CONSTITUTION:The gate heights of a first gate section 8 and a separation roller 4 are set so as to reduce the gap to a value slightly larger than the thickness of two certificates from a value slightly larger than the thickness of two pass notes. At this time the gap between the gates can be adjusted by inclining a guide adjusting lever 7. By rotating a feed roller 3 and a separation roller 4, the lowermost certificate 15a and a certificate 24 just above thereof are paid out under friction through the gate defined between the first gate section 8 and the separation roller 4 which are located below a guide plate 6. Of the paid-out two certificates, the certificate 15a is conveyed until it is detected by a sensor 12. When it is detected, a pair of conveying rollers 5 are reversed. Meanwhile, the next certificate 24a is stopped abutting against a second certificate gate section 10. The separation of the lowermost certificate 15a is thus completed.

Title: Electronic time element
Inventor: AARI SHIYUNAITAA
IPC: G04C9/08
Filed: 1980-04-03
Abstract: A time resetting operation in an electronic timepiece requires blocking of the stepping motor 1, and block of the mechanical type is avoided by the invention. A STOP switch 10 actuated by a time resetting stem of the timepiece sets to state "1" a flip-flop 11 which blocks gates 12 and 13 for controlling the passage of the pulses which drive the motor 1 through a feed circuit 2. The circuit 2 then passes a continuous current in the same direction as the last drive pulse. Thus, triggering of the continuous current leaves the position of the rotor unchanged. A counter 14 counts 1-second pulses and then resets the flip-flop 11, which causes the motor to resume normal operation. This avoids excessive discharging of the battery of the electronic timepiece if the user forgets to return the stem to its initial position after a time resetting operation.

Abstract: PURPOSE:To individually vary a current amplification factor of a bipolar transistor by incorporating a back gate electrode made of a conductive layer provided on a lower surface of an insulating film under a base region and an insulating board provided on a lower surface of the electrode and having high thermal conductivity. CONSTITUTION:When a collector bias VC, a base bias VB and a back gate boas VBG are gradually raised from 0V, a thickness of a depleted layer 18 generated in a boundary between a p-type base region 16 and an SiO2 film 13 is increased, and hence a current amplification factor is increased. Since an AlN substrate 11 is used as a substrate that has excellent heat dissipation to obtain a withstand voltage of an order of several 100V. Thus, a bipolar transistor in which a current amplification factor can be varied can be realized.
