Title: Fluid flow-rate controller for steam turbine power plant
Inventor: OZAWA SUSUMU
IPC: F01D17/00
Filed: 1992-06-12
Abstract: PURPOSE:To minimize the fluctuation of the fluid flow-rate that is transiently caused when one of systems of a fluid supplier of a duplex constitution is switched to the other and also to extremely reduce the burden of an operator. CONSTITUTION:A fluid supplier of a duplex constitution includes two systems A and B supplies the fluid to a steam turbine power plant. A fluid flow-rate controller controls the opening amounts of the control valves 1A and 1B of both systems A and B respectively and also performs the open/close control of the motor-operated valves 2A and 2B which serve the primary sides of both valves 1A and 1B respectively. A valve operating device 7 is added to usually fully opens both valves 2A and 2B of the systems A and B and then to fully closes the valve 1A if the system A has a fault. Then a controller 6 functions to increase the opening amount of the valve 1B in response to the fully closed time of the valve 2A which is fully closed by the device 7 owing to the fault of the system A although both valves 1A and 1B are usually controlled in the same opening degree. The controller also performs the control to eliminate the fluctuation of the total flow rate of both systems A and B.

Title: Power supply control system in video image distribution system and in information distribution system
Inventor: SHIMADA KOICHI
IPC: H04N5/00
Filed: 1999-06-01
Abstract: PROBLEM TO BE SOLVED: To provide a power supply control system in a video image distribution system where a power-saving operation can be realized while a viewer staying in a room staying views the output of a video source installed in another room. SOLUTION: In the case of viewing video sources 111-113 with a television receiver 104 corresponding to a sub unit 20, a viewing intent display signal generating means 20a generates a viewing intent display signal. Since a viewing intent display signal detection means 10a of a main box 10 detects the viewing intent display signal and a power supply application control means 10c completely applies power in response to the result of detection, viewers staying in their own room can realize power-saving operation of the video image distribution system.

Title: Judgment on presence or absence of thin film insulating layer
Inventor: NIWA MASAAKI
IPC: H01L21/66
Filed: 1990-06-12
Abstract: PURPOSE:To make it possible to judge the presence or absence of a thin film insulating layer formed on the surface of a conductive substance film with high precision in a non-destructive manner without using a large-scale analyzing device by a method wherein a constant tunnel current is detected in a state that a probe is brought into contact with the surface of a sample. CONSTITUTION:When a metal probe 1 installed to a piezoelectric element 2 in a direction Z is made to approach over the surface of a silicon substrate 8 by a moving mechanism 7 up to a distance of 1nm from the substrate surface, electron clouds 9 oozing out on the peripheries of surface atoms 1A and 8A of both of the probe and the substrate are linked to each other. In this state, when a slight voltage Vs 3 is applied between the probe and the substrate, a tunnel current It flows. This It value is detected and amplified by a tunnel current detection and amplification circuit 4, a feedback is made by a distance control circuit 5 in the direction Z for stabilizing the It value at a previously set constant value and a distance between the probe and the surface of a sample is controlled. As a result, the element 2 is expanded and contracted until the previously set constant value becomes the It value and the time dependency of the displacement component of the element 2 is recorded by an analyzing recorder 6 with the It value.

Title: Floating point addition and subtraction circuit
Inventor: KOJIMA SHINGO
IPC: G06F7/485
Filed: 1989-06-15
Abstract: PURPOSE:To shorten the computation time by inverting the result of subtraction when this result obtained between the exponent parts of two numbers is negative and shifting the value stored in a shift register by an extent equal to the inverted result of subtraction and then shifting the value to the right by one bit. CONSTITUTION:The data (a) and (b) on the exponent parts are used as the inputs of a subtractor 1, and a carry signal (e) is equal to '1' and '0' when the result of subtraction is negative and positive respectively. Then the smaller one of data on the mantissa parts (c) and (d) is used as the input data of a shift register 6 based on the signal (e) and the other data is used as the input data of an adder/subtractor 11 respectively. When the signal (e) is equal to '0' and '1', the result of subtraction of the subtractor 1 is stored as it is in a shift counter 5 and the inverted result of subtraction of the subtractor 1 is stored in the counter 5 respectively. Then the value of the register 6 is shifted to the right by an extent equal to the value of the counter 5. Furthermore the shifted result is shifted more to the right by one bit when the signal (e) is equal to '1'. As a result, a process to obtain two complements can be omitted and the digit matching process can be shortened.

Filed: 1990-06-13
Abstract: PURPOSE:To obtain the lens which is thin and lightweight while having aberrations improved over a range from a long distance to a short distance by using different aspherical surfaces for the upper and lower parts of the lens. CONSTITUTION:A part which has large diopter variation is arranged at the upper part of the lens and a part which has small diopter variation is arranged at the lower part to have a small aberration when a body at a relatively long distance is viewed at the upper part of the lens and a small aberration when a body at a relatively short distance is viewed at the lower part of the lens. Namely, a line OA which extends upward from the optical center O of the lens 1 and a line OB which extends downward are regarded as representative meridians of the lens 1 and curvature variation from the center O to the outer peripheral part on the front refracting surface of the lens 1 is maximum on OA and minimum on OB. Curvature variation on other meridians have intermediate values between the curvature variation on OA and the curvature variation on OB. The same effect is obtained even when this is applied to not the front refracting surface, but the rear refracting surface of the lens.

Filed: 1991-06-26
Abstract: PURPOSE:To obtain an output having the high degree of design freedom, low zero drift characteristic and high S/N by turning the light propagated in a sensing loop not to be polarized by a polarization solving means. CONSTITUTION:The optical output from a light source 1 is uniformly divided into two by a first, coupler 2. One of the light enters a second coupler 5 after passing through a polarizer 4 and is divided into two optical paths 15, 19 with the uniform intensity distributor. The light entering the optical path 15 is turned no to be polarized by a polarization solving means 8 and proceeds in a sensing loop 6 in the clockwise direction, and then enters the coupler 5 in the reverse direction. The phase of the light is modulated by a phase modulator 7 after is passes through the loop 6. On the other hand, the light incident upon the optical path 19 advances in the loop 6 in a manner completely reverse to that of the above light. In other words, the optical waves divided into two by the coupler 5 are, after propagated through the loop 6 in the opposite directions, coupled again by the coupler 5 and propagated in an optical path 14 in the reverse direction to enter a photodiode 3, where the waves are converted to electric signals and output as output signals.

Title: Delay detecting circuit
Inventor: HASHIMOTO MASAMI
IPC: H03K5/13
Filed: 1984-07-24
Abstract: PURPOSE:To reduce a short-circuit current when the output of the detecting circuit is switched, to facilitate the setting of detection levels, and increase the degree of freedom by composing the detecting circuit of two inverters having different logical levels and a selector circuit controlled with the last state signal, and selecting one of two detection levels with the last state signal. CONSTITUTION:The delay detecting circuit consists of the inverter 11 with the high logical level, inverter 12 with the low level, and, selector circuit 13. When an input signal VI varies from a low potential to a high potential, the output of the inverter 12 is inverted first because the inverters 11 and 12 are different in logical level, but the output signal 15 is initially at the low level, so the selector circuit selects the output signal 16 of the inverter 11, whose the logical level is employed as the detection level of the detecting circuit. When the input signal VI falls from the high potential to the low potential, the inverters 11 and 12 are different in inversion period and the output signal 15 is initailly at the high potential, so the selector circuit selects the output signal 17 of the inverter 12, whose logical level is employed as the detection level of the detecting circuit.
