Title: Narrow band transmission system
Inventor: MURAKAMI SHIYUUJI
IPC: G10L19/005
Filed: 1980-02-06
Abstract: PURPOSE:To narrow the necessary frequency band, by sampling the length of the basic period out of the frequency component of the voice signal and the storing the signal into a memory circuit to read it later with a reduced reading speed. CONSTITUTION:The voice signal 201 is separated into the amplitude component and the frequency component via the syllable compressor 202.

Title: Multi-point conference equipment
Inventor: ENAMI TAKAFUMI
IPC: H03M7/36
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To reduce an arithmetic operation amount considerably by mixing a received coding signal in a state of a prediction difference signal. SOLUTION: Coding signals from terminal equipments 4A-4C are received by differential decoding sections 1A-1C, in which inverse quantization is conducted and the signals are decoded into predict difference signals. Then the predict difference signals are mixed by mixer sections 2A-2C. Then the mixed predict difference signals are quantized by differential coding sections 3A-3C, coded and transmitted. Thus, arithmetic operations such as calculation of predict signals and adaptive processing of prediction devices sharing most parts of the arithmetic operations in the voice mixing processing are omitted by mixing the coded signals in a state of prediction difference signals without decoding into linear codes and analog voice signals. Thus, the arithmetic amounts are considerably reduced and a digital signal processor with high speed processing is not required.

Filed: 1986-01-27
Abstract: PURPOSE:To reduce variance in an output level after correction between sensors by using a data equivalent to the photoelectric conversion of an optical sensor when an object to be read is uniform and is of halftone as a correction reference data. CONSTITUTION:After a reference white original is set, and the switches 4 and 7 are connected to a setting mode, a low voltage is impressed on an optical sensor part 1 from a sensor power source (normal voltage, low voltage) 5. Thereby, a photoelectric conversion output equivalent to an output at a time when an original of halftone is read is inputted to a correction data generation circuit 8, and is stored at a storage part 10 as the correction reference data. Next, an original 2 to be inputted is set, and the switches 4 and 7 are connected a read mode, then an ordinary voltage is impressed on the sensor part 1. In this way, the bit of picture information of the original 2 is read, and the photoelectric conversion output is inputted to a correction circuit 9 through the switch 7. The circuit 9 corrects an inputted photoelectric conversion output using the correction reference data stored at the storage part 10, and outputs it as an electrical signal corresponding to exactly the bit of picture information of the original 2.

Title: Heat pipe electric motor
Inventor: ASAKURA HIROSHI
IPC: F28D15/02
Filed: 1987-01-26
Abstract: PURPOSE:To achieve a good heat transmission by tapering the inner circumferential wall of the heat pipe body increasingly wider from its low temperature side toward the high temperature side, and installing said heat pipe body on the rotor shaft of an electric motor. CONSTITUTION:A heat pipe body 1 is rotated on its shaft by the rotation of a rotor 7 of an electric motor 5. The sealed refrigerant 4 is evaporated by being heated on the high temperature side 10 of the heat pipe body 1 to become the evaporated gaseous refrigerant, which moves to the low temperature side 9 where it releases heat to become the condensed liquid refrigerant 4. Since the heat pipe body 1 is rotated, the condensed liquid refrigerant 4 moves toward the high temperature side 10 on the inner circumferential wall 3 on account of the centrifugal force. By tapering the inner circumferential wall 3 increasingly wider from the low temperature side to the high temperature side, the liquid refrigerant can be transmitted regardless of the positioning of the heat pipe body 1. Further, by suitably selecting the speed of the electric motor 5 and the inclination of the inner circumferential wall 3, the quantity of transmission of liquid refrigerant can also be regulated.

Abstract: PURPOSE: The die which has an elevatable member fitting into die hole and a means of energizing this to the direction opposing to a punch and which backward extrusion-works the blank of an outside diameter smaller than the outside diameter of the work with least possible process number.  
     CONSTITUTION: A moving member 3 fits into the hole of a die 2 and is made elevatable. The moving member 3 is held energized toward a punch 1 by the pressured air 4 supplied into the chamber formed thereunder or by other way. The step part of the outside circumference of the moving member 3 contacts the step part in the die 2 so that the moving member 3 does not pull out from the die 2. A pressure-receiving plate 5, which is assembled in the die 2, guides a pin 6. The pin 6 bears the bottom surface of the blank 7 and work 8 and plays the roll of a knock-out pin. When the punch 1 descends, the blank 7 is crushed and the moving member 3 descends and in the final the blank 7 becomes work 8. Thereby, preforming, upsetting, ironing, heat treatment and lubrication treatment are saved.

Normal white reference values of an even number pixel P8 are determined to be within the range of AVE(even) ±α, based on a mean value AVE(even) of white reference values of several odd number pixels P5, P3,... immediately before the pixel P8. When a white reference value of the even number pixel P8 is outside the normal range, the value is corrected into a corrected value CV(even).
