Title: Stop method for boiling water nuclear power plant
Inventor: AIZAWA MOTOHIRO
IPC: G21D3/08
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To reduce the dose rate of a residual heat removing system by starting the operation of a residual heat removing system within a range of specified reactor water temperature and a reactor internal pressure gauge indicated value. SOLUTION: With the start of operation for stopping a plant, a control rod is inserted in fuel to stop nuclear reaction. The calorific value from fuel is decreased, and at the stage where the steam generation quantity is decreased and it is difficult to keep rated reactor pressure, power generation is stopped. When the reactor water temperature reaches below about 130 deg.C (reactor internal pressure gauge indicated value 2kg/cm<2> ), warming operation is started. At the stage where a difference between the reactor water temperature and the residual heat removing system outlet temperature is about 50 deg.C or less, the warming operation is ended.  After that, reator water is passed through the residual heat removing system, and a nuclear reactor accessary cooling water is introduced to a residual heat removing system heat exchanger 23 through a piping 29 to cool the reactor water in the residual heat removing system. Thus, by the operation of setting the operation start temperature of the residual heat removing system to about 130 deg.C (reactor internal pressure gauge indicated value 2kg/cm<2> ) or less, it is possible to reduce adhesion of ion-like reactive matter to the residual heat removing system piping.

Title: Optical pickup and manufacture of its diffraction grating
Inventor: MAEDA HIDEO
IPC: G02B5/18
Filed: 1992-02-27
Abstract: PURPOSE:To make a spot of diffracted light a little larger and make the quantity of movement of the spot relatively small to variation in wavelength, and to enable stable signal detection and increase wavelength variation resistance by giving a distribution to the grating pitch of a diffraction grating. CONSTITUTION:The diffraction grating 26 has the distribution so that the pitch is different with places. Here, K1-K3 are the different grating pitches. When light 23 converged by a lens 22 is made incident on this diffraction grating 26, the diffraction grating 26 differ in angle of diffraction with the places, so the converged spot 27 is a little larger. Therefore, even if the wavelength varies, apparent spot movement is reduced and this diffracted light 24 is photodetected to reproduce a signal, thereby enabling stable reproduction. For the purpose, the diffraction grating 26 is applied to one of a first and second diffraction grating 8, 9 to enable the excellent signal detection wherein the resistance to wavelength variation is increased.

Title: System for detecting program loop spread over transactions
Inventor: MURAMOTO KAZUYUKI
IPC: G06F15/00
Filed: 1995-02-06
Abstract: PURPOSE: To detect a program loop spread over transactions by the malfunction of an application program while using a derived level value. CONSTITUTION: A reception processing means 13 for a transaction 12 receives a transaction starting message transmitted from a message transmitter 1, extracts the derived level value from its level value storage part and preserves that level value in a level value storage area 14. When it is necessary to derivatively start the same transaction 12, a program loop suppressing means 15 is activated and when the derivation level value in the level value storage area 14 is larger than an upper limit value, error processing is performed but when that level value is less than the upper limit value, a transmission processing means 16 is activated. The transmission processing means 16 updates the derivation level value extracted from the level value storage area 14, sets that level value to a level value storage part in the transaction starting message and transmits that message.  Thus, the same transaction 12 is derivatively activated.

Title: Information processor
Inventor: SHIBAZAKI NOBUO
IPC: G06F9/46
Filed: 1983-03-16
Abstract: PURPOSE:To improve interrupting function without increasing the number of external terminals by using selectively the data terminals as an interruption terminal. CONSTITUTION:When terminals P1-Pn are not used as interruption input terminals, a signal which sets all bits at ''0'' is supplied to a master register MR. Then gate circuits G1-G3 are all closed. When the terminals P1-Pn are used as interruption terminals, an output circuit of an input/output port is set at a high impedance. Then such a signal that has only one bit set at 1 is supplied to the register MR in a fixed timing so that the only bit is changed. Thus it is possible to identify an interruption signal that has just been accepted among plural ones by checking the bit pattern of the MR when an interruption signal INT2 is produced. Then an interruption is processed in accordance with the accepted interruption signal.
