IPC: E03F5/22
Filed: 1995-05-22
Abstract: PURPOSE: To rapidly detect vacuum leakage and solve troubles, by detecting the exhaust gas volume discharged from a water collecting tank by a vacuum pump and the amount of sewage discharged from the collecting tank by a pump and comparing the ratio of the exhaust gas quantity to the amount of sewage with a reference value. CONSTITUTION: The amount of exhaust gas discharged from a water collecting tank is measured by an exhaust-flow rate meter 34 installed in a vacuum pump and the measured flow rate is integrated in an exhaust gas-integrator 35 and the integrated value is output. The amount of sewage discharged from the collecting tank is measured by a sewage-flow rate meter 36 installed in a pump and the measured flow rate is integrated in a sewage integrator 37 and the integrated value is output. The ratio, integrated exhaust gas quantity/integrated amount of sewage is calculated in a dividing part 38 from the integrated exhaust quantity in the integrator 35 and the integrated discharged amount in the integrator 37 and shown in a display 39.  And further, the ratio is compared with a reference gas-liquid ratio to discriminate whether the ratio of the exhaust gas quantity to the discharged amount of sewage is under the reference value or not and indicate an abnormal state by an abnormal indicator 43.

Title: Power damper
Inventor: EHATA KEIJI
IPC: B23K26/066
Filed: 1990-05-12
Abstract: PURPOSE:To efficiently absorb the energy of laser beam and to uniformize the temperature of the absorbed surface by composing laser beam receiving surface of an outer surface of a cone whose top faces the beam irradiating direction, forming the inner surface of the cone in a stepped shape and supplying the cooling water directly to the central part of the cone. CONSTITUTION:When the cooling water is let to flow in a power damper and the laser beam 5 enters from an upper part to the cone 1, the energy of the laser beam 5 is absorbed by the surface of the cone 1 and discharged by cooling water from the inner surface. Since the absorbed surface is conical, the area absorbing the laser beam is so large that low energy density resistance of the surface can be selected. The inner surface (rear) of the cone 1 is step-formed, a contact area with cooling water is large, cooling is performed efficiently and further, the cooling water is blown out directly to the back side of the central part of the cone 1, therefore, the most efficient heat exchange is performed in the central part irradiated by the center of the laser beam having a high energy density and the temperature of the cone 1 is uniformized.

Title: Generator for clock signal synchronized with digital signal
Inventor: ITOU TAKASHI
IPC: H04L7/033
Filed: 1983-07-06
Abstract: PURPOSE:To obtain a stable clock signal in a capture range by dividing the frequency of the output of a variable frequency oscillating circuit by N to generate a reference frequency approximating 1/N of the bit frequency of an input signal and detecting a phase difference between both signals and controlling said oscillating circuit by the detection output. CONSTITUTION:If it is detected that a clock signal is not synchronized with a digital signal A to close a switch 6, the phase of an output frequency-divided clock signal E of a frequency divider 3 and that of a reference clock signal F are compared with each other. At this time, frequencies fE and fF are 1/N of fc and fb, and the frequency diference and the phase difference between fc and fb are 1/N, and the signal E is synchronized with the signal F even in case of a slight deviation between fc and fb because signals E and F are inverted at intervals of a half period. Consequently, a clock signal c is synchronized with the digital signal A easily when the switch 6 is opened. Thus, an integer N and the frequency fF are so selected that N.fFapprox.=fb is true, and a phase difference G between signals F and E is applied to an oscillating circuit 2 to synchronize them, and thereafter, the signal C is synchronized with the signal A. An LPF7 raises the gain of a phase synchronizing loop to extend the capture range.

Title: Peripheral control device
Inventor: SHIROSAKA ICHIROU
IPC: G06F13/28
Filed: 1982-07-14
Abstract: PURPOSE:To speed up an average data transfer speed and an instruction processing speed by inserting a bus cycle for information transfer between a central processing device (CPU) and a peripheral control device (PCU) on the way of a bus cycle for data transfer between a main memory (MEM) and the PCU. CONSTITUTION:Once started by a firmware controlling circuit 12, a bus cycle is generated without a firmware and data transfer between the MEM and PCU is continued until the range counter of an address/range counter 7 reaches zero. When a request to transfer information from the PCU to the CPU is detected under said condition, a firmware control circuit 12 stores the information requested by a bus register 6 and turns on a request FF 9. Consequently, a competition controlling circuit 10 receives an I/O request signal, controls the competition with a DMA request signal and is made to interrupt a bus cycle for information transfer between the CPU and PCU just after a bus cycle for the data transfer between the MEM and PCU.
