Title: Pulse beam generator
Inventor: TODOKORO HIDEO
IPC: H01J37/147
Filed: 1983-11-21
Abstract: PURPOSE:To enable fine time control by providing an aperture means that extracts a deflected charged particle beam and adjusting the generation time of a pulse beam generated at high frequency using DC voltage or low frequency sawtooth-type waveform voltage. CONSTITUTION:A trigger pulse from a sample drive circuit is input to the buffer amplifier 17 of a delay circuit and delay is applied for a long period of time through multiplexers 21-23 controlled by the CPU and then the pulse is supplied to high frequency oscillators 28 and 29 through a buffer amplifier 20. A Y-axis aperture 35 is provided at the lower part of Y-axis deflection plates 34a and 34b driven by the oscillators 28 and 29 and an X-axis aperture 39 is provided at the lower part of X-axis deflection plates 38a and 38b. Low frequency sawtooth-type waveform voltage or DC voltage is applied to the deflection plate 38b. The sawtooth-type voltage is supplied from the CPU through a register 30, D/A converter 31, and attenuator 32. As a result, fine time control from the delay for a long period of time to the delay for a short period of time is enabled for a charged particle beam 2.

Title: Natural circulation cooling apparatus
Inventor: SAGARA TAIICHI
IPC: F24F5/00
Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption of a natural circulation cooling apparatus. SOLUTION: There are provided a fresh air temperature sensor 91 for measuring fresh air temperature around a refrigerant container 92 of a condenser 82 and an indoor temperature sensor 68 for measuring temperature in a cooled room. A control section 70 controls operation of a fan 94 for performing air cooling for the refrigerant container 92 based upon outputs of the sensors. The control section 70 interrupts a fan 94 when the measured fresh air temperature is less than a predetermined threshold, and reduces, when indoor temperature is lowered, revolutions of the fan 94 correspondingly to the lowering of the indoor temperature. Hereby, there is reduced power consumption due to a motor for driving the fan 94.

Title: Invalid signal removing method for ring type optical communications network
Inventor: OGAWA HIROSHI
IPC: H04B10/03
Filed: 1993-08-11
Abstract: PURPOSE:To quickly remove an invalid signal even when invalid data such as a noise are induced a network by allowing a node which receives the signal of a preliminarily set condition to interrupt the network in a prescribed time, and remove the signal. CONSTITUTION:When a timer is activated and an input signal is not ended within a prescribed time, a first timer function 4a discriminates the input signal as the invalid signal, and interrupts the passage of a transmission signal in the prescribed time. A second timer function 4b interrupts the passage of the transmission signal in the prescribed time similarly to the first timer function 4a. The operating time of those first and second timer functions 4a and 4b is set according to the condition of the cable such as the passing time of one signal frame being the transmission signal, and the interrupting time is set so that, for example, a time when the same signal circulates through a cable 1A or 1B can be covered. Thus, the invalid signal such as the noise transmitted through the cables 1A and 1B except the proper signals can be removed from the network.

Title: Plate thickness control method
Inventor: NOSE KAZUO
IPC: B21B37/18
Filed: 1985-09-30
Abstract: PURPOSE:To increase the plate thickness accuracy by finding the corresponding quantity of the roll divergence by adding the correction quantity proportional to the rate of change of the rolling load to the correction quantity proportional to the difference in the calculated plate thickness found from the rolling load and roll divergence and the target plate thickness.

Title: Memory pack for process data
Inventor: HONDA HISAKATSU
IPC: G05B9/02
Filed: 1984-10-19
Abstract: PURPOSE:To attain the accurate and quick troubleshooting by storing and holding the process data for a fixed period of time before and after a fault is produced. CONSTITUTION:In a normal mode no contact input signal 10 exists and therefore a clock pulse 11 is always delivered from a clock 6. While the input data 9 is always stored to an RAM5. When a trouble occurs, a stop command signal is delivered to the clock 6 after a certain time elapses with a time delay 7. Thus the pulse 1 is stopped and the writing action is stopped with the RAM5. The input data so far stored is held as it is. In this case, however, the data exceeding the memory capacity are successively overflowed. In such a way, the data can be held assuredly for a fixed period of time before and after the trouble occurs.

Abstract: PURPOSE:To form an image of one frame in >=1/30sec even when the response of a liquid crystal layer is slow and to utilize the liquid crystal light valve even for motion picture display by forming a fluorescent light emission layer on one transparent substrate of a liquid crystal layer. CONSTITUTION:When laser light 9 is projected on part of the fluorescent light emission layer 7 on a transparent electrode substrate 1 with a transparent electrode 2, the light-irradiated part is excited with the light to emit fluorescent light 11. This fluorescent light 11 reaches a photoconductive layer 3 through the substrate 1 and there is impedance variation caused in an area corresponding to the light irradiated part. This variation causes variation in the frequency division of the voltage from an external power source 8 among respective layers and a voltage higher than a voltage required to drive liquid crystal is applied to the area corresponding to the light irradiated part of a ferroelectric liquid crystal layer 6; and the liquid crystal in this area becomes unstable differently from that when the light is not projected, thereby writing data with the laser light 9.

Title: Ultrasonic flowmeter
Inventor: TSURI FUSATAROU
IPC: G01F1/66
Filed: 1992-08-18
Abstract: PURPOSE:To allow the confirmation of the soundness of flowmeter by switching the operation of an ultrasonic transducer, for reflecting a part of ultrasonic beam on the corner part of a wedge, appropriately between the measurement of flow rate and monitoring of deterioration thereby making an immediate decision of deterioration in the performance of sensor. CONSTITUTION:An ultrasonic transducer 1 reflects a part of ultrasonic beam (US) on the corner part of a wedge to produce an echo in the wedge. A transducer switch 3 switches one or both transducers 1 as a transmitter or a receiver of US. A level comparator 9 compares echo level of US received at an ultrasonic receiving section 6 with a preset echo level. The switch 3 then functions to arrange only one transducer 1 on a piping 2 thus transmitting/receiving US. A flow rate operating section 7 detects the level of echo in the wedge and delivers the level thus detected to a comparator 9. The comparator 9 compares the received level with an echo level being set for monitoring of deterioration, determines the deterioration of sensor such as the exfoliation of adhesive, and displays the deterioration thus determined on a display section 8.
