Patent JP-H01250787-A (JP)
Title: Fuel assembly
Inventor: FUJITA SHIGERU
IPC: G21C3/30
Filed: 1988-03-31
Abstract: PURPOSE:To improve cooling of fuel rods at the time of an accident by forming an open window with a pressure loss larger than that of an upper tie plate in a non-heat generating range between the upper tie plate of channel boxes and the heat generating range by fuel rod groups. CONSTITUTION:A required number of openings 3 are drilled in a non-heat generating range of the lower end line L of an upper tie plate 2 and the upper end line H by fuel rod groups. At the time of normal operation, normal gas and liquid three-phase flow is flowed through plates 2. Next, loss of coolant accident occurs and an emergency core cooling system 4 is operated to form a water level WL1 by spray water W. When a water level WL2 of a bypass part 5 between boxes 1, 1 is low, steam upflow V in the box 1 is flowed away out of the windows 3 to reduce the steam upflow through the plates 2, and spray water W1 is flowed down in the boxes 1. Thus, cooling can be promoted.

Title: Demodulation circuit of pulse code modulating signal
Inventor: TAKAHASHI NOBORU
IPC: H04L25/40
Filed: 1982-05-11
Abstract: PURPOSE:To obtain a PCM signal accurately from the distorted content of information in the period of low and high levels of a reproducing signal, by using a signal obtained at a PLL circuit, and varying the threshold level of a wave shaping circuit. CONSTITUTION:When the section of a Hi level of wave shaped output (a) is narrowed than that of a substantial PCM signal, the waveform of each section is changed as shown in the waveform diagrams. Thus, when the sectin of H is widened, it is controlled that the reference voltage level of a comparator 2 goes higher and when narrowered, it goes lower, allowing to obtain the original PCM signal. Thus, an output of (k) as shown in the figure is obtained by synthesizing an inverting signal of a Q output (d) of a latch circuit 3 when the logical sum of outputs (e) and (f) and a Q output. A reference voltage is fed to a comparator 2 from the output (k) via an LPF 17 and an amplifier 18. The reference voltage is set to a potential between H and L in the steady state. Thus, in response to the fluctuation in the reproducing signal, the optimum level is set as a threshold level. The PCM signal is obtained accurately at all times.

Title: Magnetic head degaussing circuit for floppy disk
Inventor: MATSUMOTO KUNIHIKO
IPC: G11B5/465
Filed: 1987-03-31
Abstract: PURPOSE:To attain sure read/write by providing a magnetic head degaussing circuit provided with a disk-out detection means, a current switching means and an attenuation means. CONSTITUTION:Disk-out detection means 10, 11 detect that a magnetic recording medium is taken out of a floppy disk device main body, and current switching means 16, 17 apply switching to apply a degaussing current whose direction is inverted alternately in response to the result of detection of the disk-out detection means for a prescribed period. Then, the attenuation means attenuates a degaussing current produced by the current switching means within a prescribed period. Thus, after the disk is taken out of the disk drive in the floppy disk device, the degaussing current whose direction differs within a prescribed period flows to the coil of the magnetic head so as to degauss the magnetization of the core thereby always attaining sure read/write.
