Patent JP-H02179256-A (JP)
Title: Speed detector
Inventor: FUJIMAKI TORU
IPC: G01P3/46
Filed: 1988-12-27
Abstract: PURPOSE:To miniaturize a device and to prevent it from being affected by mutual inductance by disposing a bar magnet in an array in its longitudinal direction with one of the iron cores in a closed magnetic path having parallel two iron cores, and by coupling a speed detecting coil to a voice coil. CONSTITUTION:When current flows through a voice coil 4, flux B is generated corresponding to this current. The flux density of iron cores 1a and 1b in a closed magnetic path 1 is saturated by a bar magnet 2. On that account, the flux B cannot go through the iron core and flows outside the iron core as shown by broken lines. As the interval between both coils is set so that the flux B will not interlink up with a speed detecting coil 7, mutual inductance is reduced down. By controlling the current flowing through the voice coil 4 the action as a voice coil motor VCM 3 is performed and a control speed as desired can be obtained. Since the speed detecting coil 7 moves in parallel to the voice coil 4 integrally with a coupling mechanism 9, the voltage corresponding to that speed can be obtained. As the device needs only one closed magnetic path, it can be miniaturized accordingly.

Title: Electric discharge machine
Inventor: MAGARA TAKUJI
IPC: B23H1/02
Filed: 1990-11-29
Abstract: PURPOSE:To stably control a process gap, so as to achieve high speed processing at high accuracy by providing a control circuit for generating discontinuous discharge through the ON/OFF control of a first switch circuit, and a voltage holding means for holding at a fixed voltage when the circuit is turned OFF. CONSTITUTION:When a semiconductor switch 6 and a semiconductor switch 10 are turned OFF, while voltage is applied to a process gap based on a first dc power source 3 and a third dc power source 9, a voltage holding means 101 for making the process gap voltage at a fixed value, is, for example, a bypass circuit. The process gap voltage is kept high while the semiconductor switch 6 and the semiconductor switch 10 are cut, whereas the bypass circuit 101 is abruptly reduced to a zero level. This is because the electric charge stored in a floating capacity 17 is discharged through a resistor 102 by the turning ON of a semiconductor switch 103. Since the possibility of generating abnormally high average process voltage is relatively little, the process gap is stably controlled.

Title: Synchronizing system for plural cpu's
Inventor: KONYA YASUMI
IPC: G06F15/16
Filed: 1987-12-28
Abstract: PURPOSE:To acquire synchronism free from difference in a minimum time unit used for data processing by detecting the time difference between respective internal clocks of a main CPU and a sub-CPU, which perform the same processing for the same data, to switch the transmission of a processing output. CONSTITUTION:Internal clocks in the minimum time unit used for data processing are generated by respective internal clock means 110 and 120 of a main CPU 11 and a sub-CPU 12 synchronously with the clock from a fundamental clock generating means 10. Each of time difference detecting means 111 and 121 detects the time difference between the internal clock of corresponding one of CPUs 12 and 11 and that of the other; and when the internal clock of the other CPU is delayed by the minimum time unit or longer, an interruption occurs by the detection output and the processing output passing an I/O device 14 is switched to the output of one CPU through a switching means 13, and a timer counter is counted up by corresponding one of counting-up means 112 and 122 of one CPU. Thus, plural CPUs are so synchronized that the difference is not generated in the minimum time unit used for data processing.

Title: Wavelength division multiplexing packet network of which access of plurality is possible
Inventor: BAANAADO GURANSU
IPC: H04B10/294
Filed: 1994-12-21
Abstract: PURPOSE: To attain transmission of several Gbits/sec per user by wavelength division multiplexing and frequency delivery, and to provide collision-free transmission of packets between plural I/O ports a by using one optical receiver per output port. CONSTITUTION: A 1st frequency router 10 for a high speed tuning optical filter receives an input signal 15 and separates simultaneously arriving packets. Each activation part 12 for selecting packets is controlled by a packet detector/ selector 16, and when reversely biased, functions as an optical diode so as to be used for the detection of separated packets. In order to execute the process, a carrier burst consisting of several-bit length precedes the packet. After detection of a packet, the activation part 12 detecting the input packet inverts the polarity of a bias current 17 to allow the current 17 to optically pass. Then the selected packet is sent to a destination optical fiber by a 2nd router 11. Since unselected packets are erased by the activation parts 12, occurrence of a collision between received packets can be prevented.
