Title: Ion source device
Inventor: KATAGIRI GENICHI
IPC: H01J27/02
Filed: 1988-03-14
Abstract: PURPOSE:To quickly cool an ion source device after the operation of the device is stopped and adjust the cooling speed by providing the inlet of the cooling gas to cool an ion source head after plasma generation is stopped and squeezing the flow of the cooling gas with the preset static pressure.

Title: Control circuit of hot water supplier
Inventor: OOSHIO SEIJI
IPC: F24H1/18
Filed: 1984-03-27
Abstract: PURPOSE:To improve the operational convenience for a user by a method wherein the residual amount of hot water is displayed steplessly and continuously on a digital indicator. CONSTITUTION:When hot water is supplied to usage, the water flows in a feed water piping 21, resulting in generating the pulse voltages, a number of which corresponds to the amount of the flow of the water, as the output of a flow sensor 26. Said pulse voltages are sensed by a flow detection circuit 32 in order to detect the amount of the flow of the water. A residual hot water arithmetic circuit 33 calculates the residual amount of hot water by subtracting said amount of the flow of the water from the volume of a boiler body. The resultant signal is transmitted to the indicator circuit 36 of an indicator 27 so as to output on a digital display 28 after being decoded. Further, the residual hot water arithmetic circuit 33 is resent by a heating-up signal, which acts to stop the energizing of a heating device 23 when the water is heated-up by the energizing of the heating device 23. Because the residual amount of hot water is displayed steplessly and continuously on the digital indicator, the residual amount of hot water can be known accurately.

Title: Coordinate measuring apparatus
Inventor: KANEDA FUMIO
IPC: G01B21/04
Filed: 1984-03-28
Abstract: PURPOSE:To make it possible to judge which side of a body a probe is contacted automatically, by providing a means, which memorizes the locus of the probe immediately before the probe is contacted with the body and the data at the remotest point among the locus data. CONSTITUTION:Up to the time immediately before the contact of a probe 3 and a body 1, coordinate data Xi is continuously outputted from an AND gate 12 at every 10ms. A fluctuation detector 21 computes the difference between the data Xi and Xi+1. When the difference is greater than a specified value, a high-level gate signal is generated and applied to an AND gate 22. Therefore, the data are received during the period the probe 3 is moved. Even though the capacity of a FIFO memory 13 is small, the coordinate data from the remote place can be stored. When the probe 3 is contacted with the surface of the body, the data Xi indicating the locus of the probe 3 up to the time immediately before is stored in the FIFO memory 13. Coordinate data X0 of the surface of the body is stored in a buffer memory 14. The radius (r) of the probe 3 is corrected by an operation and display part 15. Thus the accurate data are displayed.

Title: Winding equipment for toroidal type core
Inventor: WADA YUJI
IPC: H01F41/08
Filed: 1988-03-16
Abstract: PURPOSE:To enable the sure guide of a wire to a roller, and the sure guide of a wire sent out from the roller in a wire-guide, by making the wire outlet narrower and smaller than the wire inlet. CONSTITUTION:In a movable wire guide 40, a groove 41 is formed, which is arranged in the following manner; one end of the groove coincides with the end of a wire guide 11 on the side of a roller pair 21, 21', and the other end coincides with a core window 3. By making the wire outlet of a groove 11A narrower and smaller than the wire inlet, it can be realized that a wire outlet of the wire-guide is narrower and smaller than the wire inlet. The width of the groove at an outlet of rollers 24, 24' is delta1. The groove width at an inlet of the rollers 21, 21' is delta2. The groove wall of outside 110 and the groove wall of inside 11i are so arranged that DELTA1>DELTA2. In the case where a wire 1 is transported in the wire-guide by the rollers, since the shape from a roller outlet to the next roller inlet becomes gradually narrow, the tip of the wire 1 receives only small resistance. Further, even if the wire tip abuts against the roller, the shock is small, because the pressure angle is small. As a result, the wire can be sent without buckling.

Title: Monitor circuit for cpu runaway
Inventor: KAJIWARA MASANORI
IPC: G06F11/30
Filed: 1986-03-18
Abstract: PURPOSE:To surely detect the runaway of a CPU by resetting the CPU when the value of a program counter is not equal to a normal level at a time point when an interruption is generated. CONSTITUTION:A timer 2 generates pulses periodically and therefore a CPU 1 receives an interruption and outputs a write clock. The write clock is not outputted if the CPU 1 has the runaway. Thus a reset pulse is generated via an FF 3 and an FF and then applied to a reset terminal RST of the CPU 1 via an OR circuit 7 to reset the CPU 1. While the contents of a program counter set immediately before the interruption is generated are held by a stack register in the CPU 1. A ROM 5 checks whether the contents of the stack register have normal values or not and gives the contents to a terminal RST of the CPU 1 via the circuit 7 when said contents have no normal value to set the CPU 1.
