Title: Synchronization method in spread spectrum communication, spread spectrum communication equipment and its system
Inventor: KOYAMA AKIHIRO
IPC: H04B1/707
Filed: 1996-01-09
Abstract: PROBLEM TO BE SOLVED: To obtain the spread spectrum communication equipment in which a self-convolution signal is suppressed, fluctuation in a peak waveform/level of a convolution signal is suppressed and a peak of the convolution signal is easily detected. SOLUTION: A surface acoustic wave convolver 11 applies convolution arithmetic operation to a reception signal and a reference signal and a peak detector 19 detects a large peak output obtained when the spread code and the reference code are coincident. An output of the convolver 11 includes a self-convolution signal being an interference signal and in order to suppress the self-convolution signal, a signal from a reference code correlation waveform pattern generator 20 and a double frequency signal of the received signal carrier frequency from the oscillator 21 are multiplied by a mixer 22 and a 180 deg. phase shifter 23 receiving the product generates a signal of an opposite phase to that of the self- convolution signal. Thus, the peak of the convolution signal is facilitated.

Title: Semiconductor device
Inventor: NAKADA TAKAAKI
IPC: H01L21/60
Filed: 1987-01-06
Abstract: PURPOSE:To obtain preferable high frequency characteristic by connecting the ground pattern of a chip surface directly to a chip placing face of a ground surface of a package or the like by means of a metallized pattern to remarkably reduce a ground inductance. CONSTITUTION:In a wafer in which a circuit element, etc. is patterned and an impurity is diffused completely on a chip 1, a semiconductor substrate is so deeply etched at part of the periphery of the chip 1 including a scribing line as to form an etching hole 4. The hole is so formed in depth deeper than the thickness on the side when the chip 1 is finally mounted in a package, etc. as to become an angle smaller than 90 deg. from the surface. The surface of the chip 1 is metallized, and a metallized pattern 5 is also formed simultaneously on the etched hole. Then, its rear surface is polished in a wafer state to expose the hole 4 and the pattern 5 from the rear surface of the wafer, and brought into contact with a solder 3 of a solidifying agent for mounting on a chip placing surface. Thus, high frequency characteristic is improved without using a bonding wire.

Title: Protective relay
Inventor: SUKEGAWA YUKIO
IPC: H02H7/22
Filed: 1989-01-09
Abstract: PURPOSE:To obtain a protective relay employing safe polyphase reclosing system and three-phase reclosing system by providing a circuit for confirming linkage based on the uninterrupted phase of its line bus and the uninterrupted phase of an adjacent line bus then performing polyphase reclosing at the bus side of its line, and a circuit for confirming the voltages at the central opposite sides of its line and performing three-phase reclosing at the central side. CONSTITUTION:Central circuit breakers 12, 22 are subjected to three-phase simultaneous interruption and faulty phases, i.e. R and S phases, are interrupted. Consequently, an R-phase linkage confirmation circuit produces O, an S-phase logic circuit produces O and a linkage confirmation circuit produces 1. A bus side circuit breaker 21 for a transmission line 24 provides 0 output to the linkage confirmation circuit, and no throw-in output is fed to a circuit breaker 11 from a reclose control circuit. Then the reclose control circuit provides a three-phase reclose output to the circuit breaker 12 because the transmission line 14 and the feeder of a generator 15 are operating synchronously. When no voltage is applied on the feeder for the generator 15, the reclose control circuit in the circuit breaker 12 provides a three-phase reclose output to the central circuit breaker 12.

Title: Automatic pump
Inventor: NISHIMURA SHIYUNICHI
IPC: F04D13/16
Filed: 1979-01-12
Abstract: PURPOSE: To perform stably the supply of air into pressure tank by connecting the negative pressure sensor of automatic air supplier to grooves formed in an impeller  rotating inside the pump casing.  
     CONSTITUTION: When the impeller rotates, the groove becomes negative pressure are therefore the chamber 18 becomes negative pressure, thereby the diaphragm 13 overcomes the pushing force of the pushing spring 14 to enable abrupt counterattack to be brought about. Thus, the chamber 15 becomes negative pressure and the air is sucked in through the valve chamber 16. Because the producing speed of negative pressure in the chamber 18 is fast and the reversal of the diaphragm 13 is made abruptly, the operation of the automatic air supplier 12 becomes more quick and more exact. When the chamber 15 becomes negative pressure by the reversal of the diaphragm 13, the inflow of water is limited because the inside diameter of the air supply opening 17 is small and the air is sucked in through the valve chamber 16 for the most part, as contrasted with the usual case where pressurized water intends to flow into the chamber 13 from the air supply opening 17 because the vapor-liquid separating chamber 9 is filled with water.

Abstract: PURPOSE:To eliminate the difference of reading density between chips by controlling the gain of a reading sensor with a reference white signal, with which a reference white board is read, defining the remaining reference white signal as a pilot signal and controlling the sensor gain. CONSTITUTION:In the CCD chip of a final edge part in a divided reading sensor 1 which is equipped with a reference white board 10, the gain control is executed to absorb the light quantity fluctuation, etc., of a light source due to a fluorescent lamp 8 by the reference white signal based on the reading of this board 10. On the other hand, concerning the remaining reading sensor, since the reference white board is not obtained, the control of the gain is not executed as it is. The reference white signal based on the board 10 is added to a pilot generating circuit 24 and added as the pilot signal. Accordingly, the reference for the gain control is secured samely as the sensor which is equipped with the board 10. Thus, the reading can be executed so as not to generate the level difference between the respective sensor chips.
