Title: Fuel assembly for nuclear reactor
Inventor: UMANO TAKUYA
IPC: G21C3/30
Filed: 1988-06-23
Abstract: PURPOSE:To increase the value of a control rod and to improve the safety of a nuclear reactor by decreasing the amt. of a nuclear material with the part where reactivity is high at the time of reactor shut-down by a part of the fuel rods disposed around a control rod guide pipe. CONSTITUTION:The amt. of the nuclear material of the fuel rods around the control rod guide pipe is decreased. The infinite multiplication factor of the fuel assembly tends to decrease when the nuclear material is decreased. The ratio of the neutrons of a high speed existing around the control rod guide pipe decreases and the ratio of thermal neutrons increases when the amt. of the nuclear material around the control rod guide pipe is decreased. The decrease of the amt. of the nuclear material around the control rod guide pipe does not lead to so much decrease of the infinite multiplication factor at the time when the control rod guide pipe is not inserted yet, but the many thermal neutrons exist at the time of insertion of the control rod and, therefore, the reaction of the control rod and the neutrons is eventually increased. This increases signifies the increase of the control rod value.

IPC: G03G15/16
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To obtain stable image quality, without a defect in an image caused by a scratch by obtaining pressing on a photoreceptor drum only by the length of a transfer material, with a pressing member whose length is changed in accordance with the length in a direction perpendicular to a moving direction, of the transfer material. SOLUTION: A CPU divides a press-contact sheet 42, so as to obtain lengths 42a-42c corresponding to the length in the direction perpendicular to the moving direction of a paper sheet, by a solenoid and a pressure device 43, based on the result of the detection of a paper size detecting sensor. Then, in a paper absent part (the part not overlapped with the width 42b, of the width 42c of the press-contact sheet), a photoreceptor drum and a conductive film are never brought into press-contact with each other by the sheet 42. Even if foreign matter is stuck to the drum and the film, the generation of the scratch of the drum due to the pressing of the drum by the sheet 42 can be prevented.  Further, in a paper present part 42b, the sheet 42 presses the paper on the film for supposing the paper, so that the contact of the paper with the drum can be more sufficient than that in the case a press-contact device is not used and transfer efficiency is increased to obtain a stable image.

Title: Nrzi system recording/reproducing circuit
Inventor: TAKAGI HITOSHI
IPC: G11B5/09
Filed: 1979-11-29
Abstract: PURPOSE: To enhance the level margin for the recording/reproducing circuit using the 4/5NRZI system to write 4 bits after converting them into 5 bits, by detecting the peak of the output waveform of a reading head by means of a delay line during the reproduction and then performing the deomdulation of data.  
     CONSTITUTION: The circuit consists of the 4/5 code converter 1, timing compensating circuit 2, writing amplifier 3, magnetic head 4, preamplifier 5, AGC6, delay line differenciator 7, LPF8, pulse shaper 9 and VFO10. In the 4/5NRZI system, the length of continuation can be set to ≤2 for the bit 0 in the converted series, and accordingly the data can be demodulated by the peak detection like the MFM system. In this case, however, the level margin can be increased by using an approximate differentiating circuit consisting of the delay line in place of the CR differenciator. At the same time, the phase margin can be secured by shifting the writing timing previously in the direction opposite to the direction where the peak shift occurs to the presumed peak shift.
