Abstract: PURPOSE: To secure the slippedness of a wheel optimally according to a friction factor on the road surface by force-feeding a brake fluid in a reservoir with a pump, and selecting it with a selecting means, then feeding the side of a wheel cylinder or master cylinder with this fluid. CONSTITUTION: In a brake piping system to a right front wheel of a vehicle, by way of example, at the time of a start of antiskid control, a pump 9 is intermittently driven. In time of pressure reducing output of a wheel cylinder 6, a master cut valve 11 is closed, interrupting the pressure of this master cylinder 6, and a control valve 21 is opened and brake fluid pressure in this wheel cylinder 6 is extracted, while an outflow valve 13 is opened, making the brake fluid pressure from the pump 9 flow back to a reservoir 25. On the other hand, in time of the pressure gently increasing output, the master cut valve 11 and the outflow valve 13 are closed each, while the control valve 21 is opened instead. With this, the brake fluid pressure from the pump 9 is discharged toward the wheel cylinder 6 without making it flow back to the reservoir 25.

Abstract: PURPOSE: To efficiently have access to a picture memory from a CPU and a video conversion part. CONSTITUTION: When the CPU and the video conversion part access the picture memory 4, a bus arbitration part 1 validates a bus of the part generating a data transfer request earlier. At the time of an access from the video conversion part, the memory 4 is made in a enabled state without fail. The succeeding request is waited for until the end of a memory access requested earlier, and at the end of the preceding request, a bus of the part generating the succeeding request is validated by the bus arbitration part 1. A data bus is shared by the CPU and the video conversion part. Thereby even if memory accesses compete with each other, the CPU is not stopped, and since the bus is shared, the efficiency of a memory access is timewise and spatially improved.

Abstract: PURPOSE:To form a constant-current source circuit with a balanced electric current inside a semiconductor substrate by a method wherein m sets of resistances which are constituted of n pieces of resistor, of an identical resistance value, arranged in parallel are arranged individually in m parts and n sets of parallel resistor are constituted by selecting one each from the m sets of resistor in the order of an identical direction. CONSTITUTION:This device is constituted of n pieces (where n = 2, 3,... ) of transistors 13 and resistor 11 which have been connected to emitters of said transistors 13. The n pieces of resistor 11, of an identical resistance value, arranged in parallel are consti tuted. The m sets (where m = 2, 3,... ) of resistor 11 constituted in this manner are arranged individually in m parts; n pieces of parallel resistor are constituted by selecting one each from the m sets of resistor in the order of an identical direction. For example, when n = 3 and m = 3, a potential difference is caused mutually at individual points 1, 2, 3; an average of individual potentials on the emitter side of the m pieces of resistor becomes an emitter potential of the individual transistors; the potentials become equal; a potential of individual points 4, 5, 6 becomes mutually equal. As a result, an electric current value of individual constant-current source circuits becomes equal.

Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To solve the problem of inversion of the dates and time of entering and leaving when it is missed to store the date and time of entering and leaving in an IC card. SOLUTION: When an IC card 3 is inserted, a control circuit 6 of an IC card reader/writer 1 judges whether the card operation of this time is operated at entering or leaving time from the date and time of entering/leaving stored in an EEPROM 18 of the IC card 3 by the preceding operation of a card. After it is judged whether the card operation of this time is at entering or leaving time, classification of A-C of working four zones corresponding to an ID number for every individual stored in a working data table are read in and it is judged whether the card operation of this time belongs to the entering time zone or the leaving time zone. Afterwards, it is judged whether the last card operation is missed or not.  Therefore, even when the card operation was missed at the time of leaving, while the record of date and time of leaving on the previous data is made blank, by the card operation at the time of entering on the next day, it is stored that the card operation was missed.
