Patent JP-H02295231-A (JP)
Title: Processor and processing method for transmitter and receiver of tone in transparent band
Inventor: ANDORIYUU BEITOMAN
IPC: H04B1/68
Filed: 1990-04-12
Abstract: PURPOSE: To eliminate phase jitters without sacrificing the response time of a system by guaranteeing that when a frequency notch is removed by using a specific control signal, the relation between the frequency and the phase of a restored signal is the same with the original signal with which a signal including a notch is obtained. CONSTITUTION: A processor for a frequency-tone-in-band(TTIB) signal consists of filters 11 and 12, multipliers 13 and 14, an oscillator 15 and an adder 16. Here, when overlapped components of upper and lower parts of a received signal are present, a control signal is obtained from two signals representing differences of a frequency and the phase between those overlapped components. This control signal is used to obtain an output signal which includes frequency components corresponding to all important frequency components in the upper and lower parts, of which a notch is removed and has a spectrum restoring the function of a frequency and a phase between frequency components of an original signal. Consequently, jitters are eliminated without sacrificing the response time of the system.

Title: Apparatus for inspecting display
Inventor: HAGIWARA NOBORU
IPC: G09F9/00
Filed: 1990-04-16
Abstract: PURPOSE:To accurately and rapidly evaluate a display medium at every pixel by constituting the title apparatus by allowing the display data of a region representing the display characteristics at every display unit of the display medium to uniquely correspond to the specific region of a sensor part. CONSTITUTION:For example, the display surface 21 of a display medium being an object to be inspected consists of four pixels 211 - 214 (the size of a display part; D1 X D2). An optical transmission path part 23 consisting of optical fibers 231 - 234 (cross-sectional shape; a circle having a diameter phi) transmits the display state of the display surface 21 to a sensor part 22 consisting of sensor elements 221 - 224 (the size of a responding part; S1 X S2) for photoelectrically converting said display state. Since the sizes D1, D2, the diameter phi and the sizes S1, S2 are constituted so as to be D1 > phi, D2 > phi, S1 > phi and S2 > phi, brightness data at every pixels 211 - 244 are certainly transmitted to the sensor part 22 through the transmission path part 23. That is, since the sensor pitch S1 is not usually equal to the pixel pitch D1, by allowing the pixels 211 - 244 to physically correspond to the sensor part 22 uniquely by the transmission path part 23, image processing can be simplified.

Title: Manufacture of single-crystal silicon wafer
Inventor: KOIKE TAKASHI
IPC: C30B33/02
Filed: 1995-03-29
Abstract: PURPOSE: To obtain excellent TDDB characteristics even when an oxide film is thin or even after heat process by performing heat treatment in the non- oxidizing atmosphere at a specific temperature and specifying the temperature increasing speed and temperature reducing speed for the heat treatment. CONSTITUTION: A wafer is made of silicon single crystal which is pulled under the condition that a ring-shaped OSF generating area, which is generated when the crystal is heated in the high-temperature oxidizing atmosphere, disappears at the crystal center. Heat treatment is performed for the wafer in the non- oxidizing atmosphere at 900 deg.C or more and 1250 deg.C or less for 10 seconds or more. The temperature increasing speed and the temperature reducing speed for the heat treatment is 1 deg.C/sec. or more. The speed of pulling the single crystal silicon wafer (crystal growing speed) is 0.5mm/min. or less. Thus, even when the gate oxide film is thin or even after heat process, the single crystal silicon wafer which has excellent TDDB(time dependent dielectric breakdown) characteristics is obtained.

Title: Power supply circuit of memory
Inventor: HORIGUCHI SHINJI
IPC: G06F1/28
Filed: 1983-06-03
Abstract: PURPOSE:To prevent the overdischarge of a secondary battery and to protect this battery for a memory using the secondary battery to its power supply, by detaching the battery when it is detected that the terminal voltage of the battery is reduced less than its limit level. CONSTITUTION:A (p) channel MOS transistor TR20 is put between a secondary battery 1 and a memory 10, and the gate of the TR20 is grounded. The TR20 conducts when ¦V1>¦VTP¦ is satisfied, where V1 means the inter-terminal voltage of the battery 1 and VTP (<0) is the threshold voltage of the TR20. Then a current is supplied to the memory 10. The TR20 becomes nonconductive with ¦V1<¦VTP¦. Thus the overdischarge of the battery 1 is prevented.

IPC: G21D1/00
Filed: 1987-04-23
Abstract: PURPOSE:To increase the penetration amount of a corrosion inhibitor to the surface of the heat transfer pipe of a crevis part, by continuing low heat output operation, which is performed after the start of a nuclear reactor in such a state that the corrosion inhibitor is injected, for 20-40hr before gradually raising output to rated output. CONSTITUTION:The container of a nuclear reactor and the steam generator communicating with the container of the nuclear reactor through a cooling material recirculation piping are provided. A corrosion inhibitor is injected in the supplied water heated by a nuclear reactor cooling material. In starting this light water cooling type nuclear reactor, the low heat output operation, which is performed after the start of the nuclear reactor in such a state that the corrosion inhibitor is injected, is continued for 20-40hr and, thereafter, output is gradually raised to rated output. Whereupon, the proper boiling convection of the supplied water in a crevis part is kept in the low heat output state of a region where the interior of the crevis part is not dried out. By this method, the penetration of the corrosion inhibitor to the crevis part becomes faster and its amount increases as compared with the concn. diffusion dominating field under zero output.

IPC: G06F3/00
Filed: 1993-04-01
Abstract: PURPOSE:To prevent errorneous judgement and to improve reliability by immediately reporting to the effect that a fuse is cut off. CONSTITUTION:When the fuse F1 is not cut off, a switch S1 is turned off. Thus, device power source VA is supplied to power source for terminating resistance use VB through D1, S1 and F1. Resistances R3, R4, R5 and R6 are set so that the voltage on a negative input terminal in a comparator 3 becomes higher than the prescribed voltage of a positive input terminal. When the fuse F1 is cut off, the voltage on the negative terminal of the comparator 3 becomes a value close to '0'. Thus, the prescribed voltage of the positive input terminal becomes higher than the voltage of the negative input terminal, and the system of the comparator 3 becomes an 'H'-level. Thus, the output terminal of a buffer 4 inverting polarity is grounded and current flows through a light-emitting element 5 and is lighted. Thus, the cut off of the fuse F1 can be informed by the lighting of the light-emitting element 5.
