Title: Charge transfer device
Inventor: ITO HIROAKI
IPC: H01L29/762
Filed: 1987-12-22
Abstract: PURPOSE:To enhance sensitivity when an injected charge amount is small, and to increase a dynamic range when the charge amount is large by providing means for varying the capacity of a floating diffused layer for converting the charge into a voltage in response to the quality of the charge. CONSTITUTION:Capacity varying means is provided with a plurality of MOS transistors switching means, and switching control signals SEL1, SEL2 are applied to sensitivity switching gate electrodes 106, 107. When a high sensitivity is obtained, the signal SEL1 is set to a 'low' level, and a signal charge transferred through transfer electrodes 4-7 and an output electrode 8 is stored in a floating diffused layer 102. In case of a low sensitivity, the signal SEL1 is set to a 'high' level to conduct floating diffused layers 102, 103, thereby varying the substantial capacity of the diffused layer. Even if the injected charge amount is small, the sensitivity is enhanced, while when the charge amount is large, the sensitivity is reduced to increase a dynamic range.

Title: Instrument and method for measuring pulse width for detecting rotation
Inventor: SUGANO YOSHIHISA
IPC: G01P3/489
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To accurately calculate pulse width of a pulse, even when a pulse interruption request and an overflow interruption request are successively issued while interruption processing is made. SOLUTION: When an overflow interruption request and a pulse interruption request are issued while a computer 3 executes certain interruption processing in response to an already issued certain interruption request, a computer 3 makes setting for giving priority to the former of the two reserved requests. When an already issued pulse interruption request exists at the time of executing the interruption processing in response to the overflow interruption request after the execution of certain interruption processing is completed, the computer 3 checks whether the count value acquired when the request is issued is closer to zero or a maximum value. When the count value is closer to the maximum value, the computer 3 calculates the pulse width of a detected signal by using the preceding and present count numbers and numbers of times of overflows.  When the count value is closer to zero, on the other hand, the computer 3 calculates the pulse width after clearing the pulse interruption request by incrementing the number of times of overflows.

Filed: 1992-12-08
Abstract: PURPOSE:To reduce loads applied to stand pipes and a shroud head due to vibration by operating a reactor pressure vessel supporting portion with a spring made of shape memory alloy and a bias spring. CONSTITUTION:A spring made of shape memory alloy and a bias spring are used as pressure contact members 20, 23, respectively, and the set temperature for the shape memory function is adjusted to the plant operating temperature. At the startup of the plant the temperature inside a pressure vessel 1 rises to the operating temperature and then the spring made of shape memory alloy is allowed to return to its memory shape by the shape memory function against the resistance of the bias spring so that the members 20, 23 are pressed into contact with the individual stand pipes 7 and the vessel 1 to horizontally support the pipes and the vessel. A stand pipe supporting portion 16 and a pressure vessel supporting portion 17, which support the pipes 7 and the vessel 1 by means of this support pressure, are rigidly connected to each other by a connecting rod 18. Therefore, each of the pipes 7 can be rigidly secured to the vessel 1. At room temperature the shape memory function does not work and the pipes 7 become free. Therefore, vibration of the pipes 7 at an earthquake during normal operation can be reduced, thus reducing loads applied to the pipes 7 and a shroud head 6.
