Patent JP-S60229543-A (JP)
Title: Optical receiver
Inventor: KURATA NOBORU
IPC: H04B10/293
Filed: 1984-04-27
Abstract: PURPOSE:To regenerate an original digital signal faithfully even in case of variation in temperature in optical fiber transmission by generating a reference voltage proportional to the level of the output potential of an amplifier during optical fiber transmission on the basis of the output of a voltage comparator and the output of the amplifier only when the output of the voltage comparator is at a low or high level. CONSTITUTION:A digital light signal 11 being made incident on a photodetecting element 12 is converted into an electric signal, which is supplied to the amplifier 13 to obtain a large electric signal 22. The output 23 of a peak holding part is compared with the amplifier output 22 by the voltage comparator 17, which outputs a digital signal 24 with the opposite polarity of the amplifier output signal. A reference voltage part 18 generates the reference voltage 25 by dividing the potential difference between the amplifier output 22 and voltage comparator output 24 through resistances 19 and 20, and it is inputted to a peak holding part 14 through a diode 21. Therefore, if the amplifier output 22 falls to a low level as shown in a figure (b), the peak holding part output 23 approximates to the low level of the amplifier output 22 with time, but never drops below the reference voltage 25.

Title: Throttle controlling for engine
Inventor: KOZUKI MASASHI
IPC: F02D41/14
Filed: 1990-03-31
Abstract: PURPOSE:To prevent the fixation of a throttle valve in the perfect opening state by carrying out correction so that the throttle opening degree controlled a throttle control means is gradually turned in the closure direction when the accelerator stepping-on quantity is over a prescribed value. CONSTITUTION:When an engine throttle control means receives the output of an accelerator stepping-on quantity detecting means and controls the throttle opening degree to a prescribed opening degree. In the region having at least a prescribed value of the accelerator stepping-on quantity where the opening degree of a throttle valve becomes nearly close to the perfect opening, if the variation of the accelerator stepping-on quantity which is detected by a stepping-on quantity variation detecting means is less than a prescribed value, control is performed so that a correcting means corrects the throttle opening degree in the closure direction as the lapse of time. Accordingly, the fixation of the throttle valve in the perfect opening state can be prevented, and since the sharp torque variation is not generated, a driver is prevented from being given a feeling of incompatibility.

IPC: G06F12/08
Filed: 1988-04-08
Abstract: PURPOSE:To shorten the use time of a bus by transferring continuous data which starts with data, which a processor requests, and is stored in a preliminarily determined address direction at the time of transferring block data from a main memory to a cache memory. CONSTITUTION:When block data including sub-block data which a processor 1 requests is transferred from a main memory 4 to a cache memory 2 because sub-block data which the processor 1 requests does not exist on the cache memory 2, continuous data which starts with sub-block data which the processor requests out of sub-block data included in block data and is stored in a preliminarily determined address direction is transferred from the main memory 4 to the cache memory 2. Thus, the bus is prevented from being used for transfer of unnecessary data to shorten the use time of the bus.

Abstract: PURPOSE:To nondestructively and rapidly measure the residual life of a ferrite heat-resisting steel with a high accuracy by measuring the spheroidizing rate of carbide precipitated on a grain boundary and evaluating the residual life by using a residual life evaluation criterion chart indicative of the relationship between a life consumption rate and the spheroidizing rate. CONSTITUTION:A variety of ferrite heat-resisting steels which have been used in such environment at a high temperature and a high pressure as in a boiler superheater tube for a thermal power generation or the like are observed under an electron microscope and the maximum and minimum diameters la and lb, respectively, of an intergranular carbide 2 on a grain boundary 1 are measured to calculate the spheroidizing rate la/lb. Then, a creep rupture test is conducted on a used material and a life consumption rate is calculated from the ratio of the creep rupture time of the used material to that of an unused material to make a residual life evaluation criterion chart indicative of the relationship between the spheroidizing rate of the intergranular carbide and a creep rupture life consumption rate. Thus, the residual life of the heat-resisting steel can be accurately evaluated without a destructive test.

Abstract: PURPOSE:To stabilize the operation for starting and stopping driving, by providing at least either of two means, namely a means for demagnetizing a bias magnetic field when starting driving, or a means for increasing and deflecting the bias magnetic field when stopping the driving. CONSTITUTION:A start-stop circuit 11 is added to a Z coil driving coil 8. The diameter of a magnetic bubble generated in a memory tip 1 is reduced in accordance with the increase of a bias magnetic field generated by a thin plate magnet 2. The attracting force of a rotating magnetic field phi generated by X and Y coils 3 and 4 affecting on the magnetic bubble is increased with the increase of the diameter of the bubble. Therefore, by demagnetizing temporarily the magnet when starting the drive of the magnetic field phi, the attracting force is increased by the same magnetic field phi and all bubbles in the tip 1 are surely moved. By intensifying temporarily when stopping the driving, bubbles are prevented from moving to a position other than the specified position due to transient oscillation generated to the driving current of the coil 3.
