Title: Multilayer cable and manufacture thereof
Inventor: SHIMAZAKI HIROAKI
IPC: H01B3/44
Filed: 1994-12-19
Abstract: PURPOSE: To provide a multilayer cable in which no bump is formed even if an economical reproduced compound is used as an insulating material. CONSTITUTION: An innermost layer, an interlayer, and an outermost layer of insulating materials are successively formed on a conductor and the interlayer is formed by extrusion of a reproduced compound and the innermost layer and the outermost layer are formed by extrusion of a compound with good quality. In this cable structure, the middle density polyethylene (π= 0.935±0.05, MI=0.3) is used for the innermost layer and the outermost layer and polyethylene cross-linked with water (ρ= 0.930±0.05, MI=0.6) is used for the interlayer. The innermost layer and the outermost layer are formed by dividing extrusion from one extruder and thus the number of extruding apparatuses can be lessened.

Title: Image forming device
Inventor: MIYAZAWA HIROSHI
IPC: G03G15/08
Filed: 1999-11-05
Abstract: PROBLEM TO BE SOLVED: To make a developing roller contact with/separate from a photoreceptor in a state where the developing roller is surely rotated at speed equal to or above specified revolving speed, to restrain vibration and to facilitate initializing work. SOLUTION: At the time of forming an image, a timing belt 18 is always rotated by the driving force of a driving motor. When the developing roller 4a is at a position B by the rotation of a rotary 3, a developing device driving gear 25 is meshed with the tooth of the belt 18, and the rotation of the belt 18 is transmitted to the roller 4a through the gear 25, then the roller 4a is rotated. At such a time, the roller 4a does not reach a position C where it abuts on the photoreceptor 8 yet. When the roller 4a is at a position C being a developing position, the rotary 3 is stopped and development is performed. When the roller 4a is at a succeeding position D where it separates from the photoreceptor 8 by the re-rotation of the rotary 3, the meshing of the gear 25 with the tooth of the belt 18 is released and the rotation of the roller 4a is stopped.  Thus, the roller 4a always contacts with/separates from the photoreceptor 8 in a rotating state.

Title: Apparatus for detecting irregular rotation
Inventor: TAKADA MASANOBU
IPC: G04D7/04
Filed: 1986-12-26
Abstract: PURPOSE:To easily discriminate the inferior of a gear, by rotating a wheel train by force due to air and detecting rotational irregularity generated by the disorder of the wheel train. CONSTITUTION:The air blown out from an air nozzle 2 is blown to one gear of the wheel train of a watch movement 1 and, when the tooth chips of the rotated gear are magnified by a microscope 4 and the output of a photodetector 5 is observed, the ON/OFF signal synchronous to each of the tooth chips of the rotated gear is obtained. Next, the output of the detector 5 is inputted to an F/V converter 6 and the signal proportional to the rotational speed of the gear is outputted from the converter 6. Subsequently, the output of the converter 6 is inputted to a comparator 8 through a peak detector 7 and compared with the output of a rotation irregularity tolerant value setting circuit 9. When the output of the converter 6 is larger than a rotation irregularity tolerant value, the comparator 8 outputs an inferiority signal. By this method, the inferiority of the gear can be easily judged.

Title: Radio wave distance detecting device
Inventor: KAMIYA TSUYOSHI
IPC: G01S13/36
Filed: 1988-12-14
Abstract: PURPOSE:To suppress a fact that an interference of a transmission wave and a reception wave becomes an error of a measured value by forming a modulation waveform of the transmission wave to a square wave, and setting its duty ratio to the lowest level which can measure a distance. CONSTITUTION:A transmission wave oscillated by an oscillator 12 is modulated by a modulator 13, and outputted from a transmission antenna 10 only during the time t1 in a period T. This modulated wave is formed to a square wave, and its duty ratio is set to the lowest level which can measure a distance. An emitted radio wave is reflected by the ground, and received by being delayed by 2l/c (c denotes a velocity of light) in accordance with altitude (distance (l)) by a reception antenna 11. The received signal passes through an amplifier 14 and detected by a detector 15, its phase is compared with a phase of a modulation signal from a generator 16 by a phase comparator 17, and a phase difference is outputted. From its output, the distance (l) is calculated. In such a way, when a reflected wave is being received, the transmission wave is not outputted, therefore, an interference error of the transmission wave and the reception wave is generated.

IPC: G01N21/59
Filed: 1988-12-14
Abstract: PURPOSE:To prevent contaminated cooling water from being used by generating an alarm in response to the signal of contaminant detecting means of water in a cooling water tank. CONSTITUTION:A light emitting element 12 in a light emission device 8 is energized to always emit a light. A photodetecting element 13 in a photodetector 9 receives the light to operate an alarm generator 10, and an alarm lamp 11 is turned OFF. Thereafter, when a time is elapsed and cooling water is contaminated, the light from the light emitting element does not arrive at the photodetecting element, and the photodetecting element is turned OFF. Thus, a transistor 14 is turned ON to turn ON the alarm lamp 11 to externally notify the contamination of the cooling water.
