Patent JP-H11127593-A (JP)
Title: Multichannel motor winding machine and pulse-width modulation control device
Inventor: CHAPMAN JOHN H
IPC: H02P27/06
Filed: 1998-06-26
Abstract: PROBLEM TO BE SOLVED: To reduce harmonic distortion by constituting a winding machine, so that it contains electromagnetic winding which is provided with a device having at least two channels and producing at least one current waveform. SOLUTION: Windings in respective phases of the motor of the machine comprise a group of separate conductors C0-C9 which run through the slots in the motor and the path of which is specified so that they run to a common bundle. Separate conductors need four power switching elements 21-32 arranged in an H-bridge structure, and the sum of all the currents passing through the conductors C0-C9 an arbitrary instant is detected by a current sensor 33. The effective switching frequency found in each phase of the motor is made equal to a value obtained by multiplying the switching frequency of power switches to the conductors C0-C9 in series by the number of the conductors by sequentially turning on/off the power switches.  As a result, the power switches can operate at a frequency which is relatively low and thus highly efficient, and target current waveform can be tracked with a high resolution. Therefore, harmonic distortion is reduced.

Abstract: PURPOSE:To improve dehydration efficiency by pressing operation in the stage of dehydrating sludge, etc. contg. a large amt. of water by utilizing the expansion by the pressurizing fluid of a diaphragm as a pressurizing means. CONSTITUTION:A moving belt 24 of a water permeable filter cloth carrying materials 22 to be pressed such as sludge is circulated and moved through an inlet 18 of a hollow vessel 10 consisting of a top plate 12 provided with a hollow part 16 and a flat bottom plate 14. In the hollow part 16 of the plate 12, a diaphragm 26 made of an elastic material such as rubber is provided at all times above sludge 22 and pressurizing fluid is supplied through an inlet 28. The diaphragm 26 expands to press the sludge 22 and to squeeze out the water in the sludge 22. The water is discharged through the belt 24 which is a water permeable filter cloth. The sludge is discharged as dehydrated cake through an outlet 20.

Title: Tagging device
Inventor: MAIKERU JIEI KUUPAA
IPC: B65C3/18
Filed: 1988-07-20
Abstract: PURPOSE: To attach a tag to a neck of a bottle by providing a tag with an aperture, providing a coating layer of a release material on a surface of the tag, and making a portion not covered by strip-like tags non-adhesive. CONSTITUTION: This system uses a common strip constituting a series of tags 11 each having an aperture near a tip thereof, and the tags can annularly surround a neck of a bottle moving along a conveyor by the apertures. A support strip 10 is coated with a layer 14 of a pressure-sensitive adhesive, whereby the tags 11 are fixed to strip 10. Each tag has a coating 15 of silicone or other release material on a surface as fixed to the support strip 10. First, the adhesive 14 is applied on the whole of the upper surface of the support strip 10. However, since the adhesives in portions not covered by the tags are inactivated by a varnish applied to these portions and irradiation of UV rays, the strip to support the tags can be formed in a roll state.

Title: Digital-analogue converter
Inventor: KAWAYAUCHI NOBORU
IPC: H03M1/10
Filed: 1980-12-22
Abstract: PURPOSE:To eliminate a conversion error, by applying the signal of an upper bit of a digital signal to an analogue output signal through a resistance. CONSTITUTION:The most significant bit B1 out of input n-number bits of a D/A converter 4 indicates the polarity. The signal of this bit B1 is given to an inverter 1. A voltage E is taken out from a middle 2a of a resistance 2 provided between the input and the output of the inverter 1 and is applied to the output of the D/A converter 4 through a resistance 3. The variable resistor 2 is regulated to generate the voltage E of the same quantity as the conversion error, which is caused by polarity switching of the bit B1, and this voltage is applied to the analogue output, thereby cancelling the conversion error.

Title: Call current supply system for private branch exchange
Inventor: TANIGUCHI KOICHI
IPC: H04M19/00
Filed: 1985-08-21
Abstract: PURPOSE:To secure a satisfactory speech quality by supplying a call current having the same value as the line current sent from a station exchange to an extension telephone and actuating the automatic pad of the telephone as if an ordinary telephone set were set in the set place of a private branch exchange. CONSTITUTION:A call current supply circuit B in the line circuit 4 of a private branch exchange 1 supplies the call current to an extension telephone set T. A trunk line trunk 6 contains a circuit S to detect the value of the call current given from a station exchange 3. The call current ICO sent from a station is detected by the detecting circuit S and this detected value is sent to a control circuit CTL. The CTL controls the circuit B and sets the call current value IL supplied to the telephone set T at the same level as the current ICO. Thus the automatic pad of the telephone set T can be actuated in response to the length of the communication line set between both exchanges 1 and 3.

Title: Optical disk recorder
Inventor: SUZUKI YOSHIAKI
IPC: G11B7/125
Filed: 1989-07-14
Abstract: PURPOSE:To make satisfactory the rise of a laser beam output while making an ALPC loop effective when a mode is switched by providing a compensating current source and superimposing a compensating current from this source to a driving current for recording. CONSTITUTION:A constant current circuit 50 is controlled by a pulse PA for compensating current control from a compensating current control circuit 78 and a current iA for compensation is made to flow with a pattern corresponding to the waveform of this pulse PA. This current iA for compensation compensates delay and rounding for the rise of a current iC for recording and an added value iA+iC of these currents is supplied to a laser diode 46 as a current ip to rise up sharply from the start of recording. Thus, a laser diode 48 can obtain an optical output to exceed a recording threshold value immediately from the beginning when the mode is switched from a reproducing mode to a recording mode.
