Patent JP-H02199878-A (JP)
Title: Light emitting element driving circuit
Inventor: YAMASHITA KIICHI
IPC: H01L33/00
Filed: 1989-01-30
Abstract: PURPOSE:To suppress the oscillation of a driving current induced by the parasitic inductance of a bonding wire or a damped vibration and to supply a satisfactory driving current responding to input data by cross-connecting the collectors to the bases of paired differential transistor through an impedance circuit. CONSTITUTION:Since parasitic inductances 5, 6 exist at the collectors 1c, 2c of transistors 1 and 2, a voltage is generated in response to variation in a driving current. This voltage is negatively fed back to the bases through a junction capacitance Cbc between the bases and the collectors of the transistors 1, 2, energy is communicated between the capacitance Cbc and the parasitic inductances 5, 6 to excite an oscillation or a damped vibration. Impedance circuits 101, 102 so operate as to suppress vibration generated by the communication of the energy between parasitic elements by positively feeding back the voltages of the terminals 1c, 2c to terminal 2b, 1b. Thus, since two charging and discharging currents flow to the inductances 5, 6 to cancel to each other, a current having no vibration can be supplied to a light emitting element.

Title: Intake control device for engine
Inventor: KAWAMOTO MINORU
IPC: F02D41/08
Filed: 1988-01-27
Abstract: PURPOSE:To suppress lowering of engine speed by correcting a mixture increased with increasing of an engine load such that the mixture is more increased, when an air-fuel ratio of the mixture supplied to the engine is fixed on the lean side, than when non-fixed. CONSTITUTION:In an engine 1, by a control unit 9, an air-fuel ratio is controlled in a low speed and low load operation ranges including an idling range while a mixture is increased with increasing of an engine load. In this case, a main air bleed passage connecting a nozzle 14 of a carbureter 4 to a fuel chamber 16 is controlled for opening/closing, to control the air-fuel ratio. A richer 10 is arranged in an emulsion passage 12 bypassing a throttle valve 13 and venturi 15, and by the valve body 11 of the richer 10 the mixture is increased. Thus, when the air-fuel ratio is fixed on the lean side, the mixture is furthermore corrected to be increased.

Title: Ink jet recorder
Inventor: YAMADA HIROAKI
IPC: B41J2/14
Filed: 1987-01-28
Abstract: PURPOSE:To improve safety and productivity, by employing a combined mechanism of a longitudinal effect type lamination piezoelectric ceramic and a lever in order to reduce the volume of a pressure chamber in a print head, thereby lowering the pules voltage to be applied onto the piezoelectric ceramic. CONSTITUTION:One end portion 39 of a F-shaped lever 38 is secured to the vicinity of respective pressure chambers on the outer face of a print head 1 manufactured by laminating and jointing substrates 11-14, and a fulcrum 40 in the central portion is secured to the outside face of the print head 1. A piezoelectric ceramic mechanism 5 comprising a longitudinal effect type laminated piezoelectric ceramic 42 is fixed between the other end 41 of said lever 38 and the outer face. Upon application of voltage from a pulse generator onto said ceramic 42, the ceramic d2 extends to push up one end portion 41 of the lever 38, thereby the other end portion 39 is pushed down. Consequently, volume of a pressure chamber 27 decreases, and pressure is applied onto the ink in the pressure chamber 27 so as to eject an ink drip 6 through a nozzle 25. Consequently, pulse voltage being applied onto the piezoelectric ceramic can be lowered to a great extent.

Title: Discrimination method for leaked signal in communication line
Inventor: KASHIWABARA TOMOYA
IPC: H04Q9/00
Filed: 1987-01-30
Abstract: PURPOSE:To attain accurate discrimination by providing a number representing a destination district and a scheduled bypass district to an outgoing signal as an address, and erasing a number representing its own address and a district passed by the outgoing signal and updating the number of the district passed by the incoming signal. CONSTITUTION:Scheduled bypass district numbers (A0-A3) till the destination slave station 4 are written in an address layer 13 of an outgoing signal. The outgoing signal is bypassed at first through the district A0 and sent to the district A1. In such a case, the district number A0 already passed by is erased from the outgoing signal address layer 13. The processing above is repeated similarly. Thus, the slave station 4 regards only the outgoing signal having its own district number left as a true signal. The scheduled passing district number of the incoming signal and the district number of the slave station 4 are written in the address layer 18 of the incoming signal from the slave station 4. When the signal is sent to the district A2, the district number A3 of the address layer 18 is rewritten into the district number A2 to be passed by from now. The processing above is applied similarly to the following operation. Thus, the master station 3 regards only the incoming signal whose address consists of one district number as the true signal.

Filed: 1992-02-04
Abstract: PURPOSE:To enable taking out plural signals by using optical fibers which are divided into sectional shape by regions and mounting a pair of the light emitting and receiving optical fibers to a rotary disk for detection having a small diameter. CONSTITUTION:A shielding and opening plate 4 is rotated by rotation of a shaft 5 connected to the revolving shaft of an internal combustion engine. Light is transmitted by the light emitting side optical fiber 2 and light receiving side optical fiber 1 mounted to a detecting section 3 supporting the optical fibers. Revolution signals are obtd. by light receiving circuits 10, 11. The optical fiber 1 which has the sectional shape divided by the regions for one light emitting part and is divided into a plurality at the end face on the opposite side is used for the light receiving part. The optical fiber 1 is disposed by being bundled in a pair of the light receiving parts in such a manner, by which the plural signals are detected in the same part with one system of the slits provided on the rotating body 4 or the reflection plate and, therefore, the size of the rotating body is reduced. Since these signals are detected from the same part, the accuracy is high and the phase deviations of the respective signals are prevented.

Title: Circuit for setting dma transfer start command
Inventor: OKADA ATSUSHI
IPC: G06F13/28
Filed: 1987-01-29
Abstract: PURPOSE:To realize the continuous DMA transfer at high speed by setting a DMA transfer start command at a DMA controller after the end of the DMA transfer so that a command for the next transfer can be set at the controller during the DMA transfer. CONSTITUTION:A latch 4 holds a DMA transfer start command setting signal 5 and outputs this signal 5 as a DMA transfer start command signal 3 after the end of transfer by a DMA transfer end signal 6 received from a DMA controller 1. The controller 1 works with a parameter setting signal 2 which decides a transfer way and the signal 3. Therefore the signal 5 held by the latch 4 is set as the signal 3 by the signal 6 after the end of transfer. The controller 1 works with the input of both signals 2 and 3 after the end of transfer. Thus a transfer start command is set. In such a way, the continuous DMA transfer is carried out at high speed.
