Title: Automatic relief device for fluid
Inventor: FURUBAYASHI YOSHIHIRO
IPC: B63B25/16
Filed: 1981-06-16
Abstract: PURPOSE:To prevent the consumption of controlling nitrogen gas from increasing due to the rupture of a plate covering a through-hole under normal condition by a method wherein a bimetal, which closes the through-hole under the condition that cryogenic liquid is not in contact with said bimetal and opens the through-hole under the condition that cryogenic liquid contacts with said bimetal, is provided at the through-hole formed in the main body of the device. CONSTITUTION:The through-hole 10a is bored at the center of the flange-shape main body 10 and a fitting recess 10b is formed concentric to the through hole 10a on the top surface of the main body 10. The bimetal 11 is housed in the fitting recess 10b in such a manner as to cover the through hole 10a and fixed to the bottom surface of the fitting recess 10b by means of a machine screw 12 at its end. Said bimetal 11 is normally in the form of a flat plate and its free end covers the through-hole 10a by seating onto the bottom surface of the fitting recess 10b through adhesives coated over the under surface of the bimetal 11. However, when cryogenic liquefied natural gas comes into contact with the bimetal 11, the binetal 11 warps upward, resulting in opening the through-hole 10a by the exfoliation of adhesives off the bottom surface of the fitting recess 10b.

Title: Excitation controller for rotary equipment
Inventor: YAMADA TSUTOMU
IPC: H02P9/14
Filed: 1979-07-18
Abstract: PURPOSE:To prevent shock from affecting on the generator at application of signal by converting the overexcitation control signal into a stepped on with a counter circuit before being fed to AVR. CONSTITUTION:The deviation detector 8 outputs the deviation between the allowable field current according to the internal cooling water temperature of the generator 1 and the field current. When the generator voltage is out of the normal operating range, the relay starts to work to feed the overexcitation control signal to AVR4 immediately. When it is within the normal operating range, after excessive field current continues for the first specified period, the timer 17 actuates the relay to convert the overexcitation control signal into the one rising by steps with the counter circuit before it is transmitted to AVR4. With further continuation of the excessive field current, the timer 19 actuates the relay 20 to feed the overexcitation control signal to the AVR4 directly, not through the counter circuit.

Title: Learning control system
Inventor: NAKAMURA YUJI
IPC: G05B13/02
Filed: 1990-04-06
Abstract: PURPOSE:To obtain the step answer of a control subject with no direct measurement by sampling the ramp answer of the control subject and using the value obtained by dividing the differential value of the ramp answer by the slope of a ramp command as the step answer. CONSTITUTION:A step answer Hk is obtained as Hk = (Rk - Rk-1)/D based on the sample value Rk of the ramp answer obtained by sampling the step answer of a control subject. In this equation D shows the slope of a sampling interval set in a steady state of a ramp command or the ramp answer. Based on this step answer, a future control deviation is estimated and the control input is decided so that the estimated control deviation is minimized. Thus a follow-up control system having the high accuracy is obtained.

Title: Laser device
Inventor: MOGI KUNIJI
IPC: H01S3/23
Filed: 1983-05-26
Abstract: PURPOSE:To amplify a laser beam reflected and passed at the portion of the high energy density of a laser beam in a laser oscillating and amplifying device having a laser oscillator using an unstable resonator and a high stage laser amplifier by disposing a local reflection mirror between laser amplifiers. CONSTITUTION:A laser beam 11 emitted from a laser oscillator 1 using an unstable resonator is amplified by a laser amplifier 2. At this time, the energy density in the vidinity of the center of a laser beam 12 becomes very strong. This strong portion is reflected in a direction 13 by a fully reflecting coating unit 5 of a local reflecting mirror 3, and the laser beam 14 passed through the nonreflecting coating unit 6 is amplified by a laser amplifier 4 of the rear stage. Even when the laser amplifier is further increased, the local reflecting mirror is disposed between the laser amplifiers. When the energy density in the vicinity of the center of the laser oscillator using the unstable resonator is strong in the degree of damaging the optical components, the local reflecting mirror is disposed between the oscillator and the amplifier. In this manner, the laser amplifier and the optical components can be prevented from damaging, thereby preferably transmitting the laser light as its pattern.

Title: Differential switch circuit
Inventor: YASOHARA MASAHIRO
IPC: H03F3/343
Filed: 1984-05-10
Abstract: PURPOSE:To attain a complete switch of a differential output despite an extremely small potential difference obtained between both inputs of a pair of differential transistors, by using a pair of differential transistors whose emitters connected to each other and a mutual output preventing device that delivers only larger one of both outputs of said two transistors and also inhibits the smaller output respectively. CONSTITUTION:The collector currents of transistors TR4 and 5 are set at I11 and I21; while the collector currents of TR20 and 12 are set at I23 and I13 respectively. At the same time, the voltage impressed to input terminals 22 and 23 are set at V11 and V12. When a difference is produced between V11 and V12, the larger one of collector currents of both TR4 and TR5 is delivered as it is. While the output of the smaller collector current is inhibited by the larger one. Thus a differential switching action is over. A larger voltage difference is needed between V11 and V12 as long as both resistances 13 and 21 are not set at ''0''. Thus the differential switching sensitivity can be controlled by means of resistances 13 and 21.
