Title: Residual fuel gauge for car
Inventor: SUZUKI KOUICHI
IPC: B60K15/077
Filed: 1983-10-14
Abstract: PURPOSE:To indicate residual fuel accurately by indicating such level as the fuel consumption operated on the basis of fuel injection pulse is subtracted from previous level when the car speed is zero and the detected level of residual fuel is differed more than predetermined level from previous one. CONSTITUTION:When the car speed is not zero or under travelling, a switching circuit 7 will feed the operated residual level from a time averaging circuit 3 directly to driver circuit 4 and indicated on an indicator 5. When the car speed is zero, the switching circuit 7 will feed the operated residual level LB to a residual amount decision circuit 11 to be compared with previous level LA. If the difference is higher than the setting level, fuel consumption corresponding to the large count is subtracted to feed the difference to a driver circuit 4. The residual amount to be indicated in such a manner is an accurate level where the amount of fuel consumed during idling is subtracted from the amount prior to inclination of chassis.

Patent JP-H0243168-A (JP)
Title: Sheet conveyor
Inventor: HIGUCHI TERUYUKI
IPC: G07D9/00
Filed: 1988-07-30
Abstract: PURPOSE:To make sheets formable in line in a process of movement by holding each sheet between both front and rear support members, and conveying it as being held by both these support members at a specified interval. CONSTITUTION:When bills P at a stacking position are moved to a delivery position, a slider 175 is moved to this delivery position side, while another slider 163 is also moved, whereby an interval between a front plate 109 and a backup plate 111 is not narrowed at one once. Consequently, the bills Plying between the front plate 109 and the backup plate 111 are not restrained even during movement, and they are aligned by vibration or the like while each lower end of the bills P is traveled on a guide 105. Therefore any paper jam is hard to occur at the time of delivery. Thus, such a conveying mechanism that moves the bills P from the stacking position to the delivery position is utilized, whereby effective moment and alignment can be done without installing a special aligning space and requiring extra alignment time.

Title: Gaas semiconductor device
Inventor: NISHIZAWA JUNICHI
IPC: H01L33/20
Filed: 1988-07-30
Abstract: PURPOSE:To offer an integrated circuit provided with an optoelectric transducer, which is operated at a very high speed, by a method wherein a light-emitting diode is provided so as to be adjacent to the drain region of a vertical type static induction transistor constituted in a manner that the collector region of a bipolar transistor is common with the gate region of the static induction transistor. CONSTITUTION:An n<+> region 61 is used as a source of a driving static induction transistor (SIT) and an n<-> region 62 is used in common as a channel of the driving SIT and as a base of a load bipolar transistor (BJT). A p<+> region 63 is an emitter of the load BJT and a p<+> region 64 is a collector of the load BJT and at the same time, is a gate of the driving SIT. An n<+> region 66 is a drain of the driving SIT. When a driving SITT3 is in a state of disconnection, a drain of the T3 is in a high level. Therefore, a current to flow through a load transistor T2 flows through a light-emitting diode D and light is radiated outside. When the T3 is in a state of continuity, the output of an output terminal of the T3 becomes a low-level one. Therefore, no current flows through the diode D and no light is radiated.

Title: Television receiver
Inventor: MEEE UINKU
IPC: H04N5/50
Filed: 1989-07-26
Abstract: PURPOSE: To integrate the circuits of a television receiver by reducing signal connection lines between parts. CONSTITUTION: A frequency detector circuit is connected to the output terminal 99 of an intermediate frequency amplifier 47 and connects the input terminal 4 to the output terminal 43 of a turner circuit 4. The frequency detector circuit is made a counter 19 and it is connected to the output terminal of a reference signal oscillator 97 via a measuring gate 115. The oscillator 97 forms one part of a phase connection loop 113 connected to the output terminal of the intermediate frequency amplifier 47 and connects the output terminal of the oscillator 97 to the reference signal input terminal 111 of a synchronous video signal detector 57. Thus, the measuring gate can be operated by a measuring gate signal synchronized with the line frequency of a received TV signal.  When the frequency detector circuit is formed as the counter 119, a circuit which requires the terminal is not necessary for the integrated circuit and digital data of a correction signal can be obtained without conversion. Thus, the operation of the measuring gate 115 by the measuring gate signal does not require the connection of a frequency reference at all.
