Patent JP-H01179194-A (JP)
Title: Method and circuit for driving display element
Inventor: ARAI YASUO
IPC: G09G3/04
Filed: 1988-01-08
Abstract: PURPOSE:To prevent the generation of a noise and a surge by varying gradually a driving signal at the time of transition from non-lighting to lighting and from lighting to non-lighting, in case of driving a display element. CONSTITUTION:When a lighting instructing signal Si supplied to a shift register 90 becomes an L level, output terminals 01-03 of the register 90 become successively an L level by a clock phi, and those L levels are driven by buffers 91-93. On a node 94, an added value of L level outputs of the buffers 91-93 appears and becomes intensive stepwise, and in accordance therewith, a current I flowing to an LED 80 increases successively and it is lighted. On the other hand, when the signal Si becomes an H level, by following the course being reverse to the foregoing, the current I of the LED 80 decreases successively and it is turned off. In such a way, the generation of an electrical noise and the power source surge of a spike property can be prevented.

Title: Exhaust gas afterburning device
Inventor: NISHIYAMA TOSHITAKA
IPC: B63H21/32
Filed: 1989-01-10
Abstract: PURPOSE:To eliminate environmental pollution as well as dirt on peripheral equipment by performing afterburning treatment of unburnt particulates in exhaust gas with a laser beam shield to provide clean exhaust gas. CONSTITUTION:Laser beam from a laser generating device 7 is entered in between reflecting plates 12 opposite each other to encircle or put the exhaust gas passing space between than and shaken in on plane by a beam searching device 8 to form a shield 9. Exhaust gas from an engine crosses this laser beam shield 9 to pass through a beam irradiation box 10, and then unburnt matters in exhaust gas are exposed to the laser beam. At this time, as the laser beam does not operate on the body of the exhaust gas, the exhaust gas itself is not heated and the particulates of the unburnt matters are only abruptly heated to a high temperature. It is thus possible to give effective and complete afterburning to the particulates of the unburnt matters and provide stable and clean exhaust gas without black soot.

Filed: 1981-01-10
Abstract: PURPOSE:To test the laser range measuring device accurately by delaying the output light of the laser range measuring device by a pulse delaying circuit, and returning the light to said laser range measuring device. CONSTITUTION:The large pulse irradiated from a transmitting telescope 2 of the laser range measuring device B passes a condenser lens 7 and a filter 8, and is received by a light receiving element 11. The large pulses is converted into the electrical pulses and applied to a delay circuit 11. The pulse is delayed in said circuit by a specified time, and thereafter applied to a light emitting element 13, when the electrical pulse is corrected into the optical pulse. The pulse is converted by a condenser lens 14 and inputted to a receiving telescope 3 of the laser range measuring device B. The delay time t1 of the circuit 1 is set to the time corresponding to the range R1 to be tested, so that the equation t1= 2CR1 (where C is light velocity) is established. When the laser range measuring device B is operated, the range R1 is displayed on a range display 6. If the correct range R1 is not displayed on said display 6, it is judged that the laser range measuring device is defective.

Title: Manufacture of thin clad sheet stock
Inventor: UEHORI YUJI
IPC: B23K20/04
Filed: 1988-01-11
Abstract: PURPOSE:To execute cold rolling without causing a meandering and to prevent the rippling of a joining face by executing rolling by expanding slightly the diameter near the center part in the axial direction of the barrel part of at least one roll of a rolling roll couple. CONSTITUTION:Rolling is executed by using the roll whose diameter of the center part or its vicinity in the axial direction of the roll barrel part of at least one roil R1 of rolling roll couple R1, R2 is expanded only slightly relatively. At this time, the force received from the roll first acts on the vicinity of the width center part of a material S, so the width center part is first joined. Meandering is therefore difficult to cause even if the joining position of the width both sides to be joined by delaying timely differs. If the diameter of the center part or its vicinity of the roll R1 is relatively too large a rolling reduction is exerted too much on the width center part of a rolled stock S to worsen the shape of the width center part.

Title: Automatic feeding device for original
Inventor: TANEDA KANGO
IPC: B65H3/06
Filed: 1988-01-11
Abstract: PURPOSE:To permit a thick sheet of paper to be transported and located, by sensing the time from a sheet feed roller to a sheet sensor, applying a pressure to a pre-resist roller by a solenoid when the sensed time exceeds a certain specified value, and thereby increasing the feeding force. CONSTITUTION:A sheet feed roller 3 exerts a weak transport force which can feed a sheet of standard type. Before a belt transport device 15 on a platen 16, a pre-resist roller 10 and a gate 7 are furnished for sheet transport to the platen 6 and location of the leading edge. The pressure of the pre-resist roller 10 can be varied by a solenoid 12, and a sensor 6 is installed in the position before it. When a thick sheet is sent, the transport force of the feed roller 3 weakens, and the time for attainment of the sensor 6 will be longer. If it is sensed, the solenoid 12 is actuated to increase the pressure of the pre-resist roller 10, which increases in turn the feeding force. Thus a thick sheet can be transported and located surely.

Title: Relay interface circuit
Inventor: MIYAHARA MASATOSHI
IPC: B60L3/08
Filed: 1985-01-10
Abstract: PURPOSE:To reduce the number of relays by controlling ON or OFF a frequency signal circuit and a level signal circuit by one relay. CONSTITUTION:When a signal relay contact 41 corresponding to an automatic train stopping device (ATS) or automatic train control device (ATC) is closed, the coil 5c of a repeating relay 5 is energized. Thus, a transfer contact 5a is closed, and the frequency signal of an input signal 12a1 is output from an output command line 12b1. Since a transfer contact 5b is closed, the output signal of an output line 131 for monitoring becomes '0'. Thus, the number of relays reduced to simplify the circuit configuration.

Title: Phase comparator circuit
Inventor: ARAI MITSUYOSHI
IPC: H03K5/26
Filed: 1987-01-08
Abstract: PURPOSE:To connect respective input/output terminals of FFs as prescribed to compare a phase difference by providing four RS FFs having NAND gate constitution and NAND gates which receive their Q outputs and inputting signals to be compared to set terminals of first and second FFs. CONSTITUTION:When a control signal 21 is '1', phases of a reference signal 6 and an input signal 7 are compared with each other as conventional. When it is '0', an FF 8 is reset and the Q output goes to '1', and a Pch FET 16 is turned off. An FF 9 is reset also, and an Nch FET 17 is turned off by inversion 16 of the -Q output. Consequently, the output of a charge pump 2 has a high impedance. Even if the reference signal 6 is disturbed or broken during this time, a pump output 18 is not changed because phase comparison is inhibited. Consequently, if this circuit is used to constitute a PLL circuit, the output of a voltage controlled oscillator VCO 4 is N-number of times as high as the frequency of the reference signal 7 by the conventional phase comparison when the control signal 21 is '1', and the charge pump output goes to the high level when the signal 21 is '0', and the state just before the change to '0' is kept to keep the output of a low-pass filter LPF 3 constant and the output of the VCO 4 is kept at a certain frequency.
