Title: Encoding and decoding method
Inventor: SATOU YOSHIO
IPC: G06F11/10
Filed: 1983-12-24
Abstract: PURPOSE:To prevent the degradation of a signal quality due to a line error by substituting a decoded signal, which is obtained by decoding a code including unrecoverable errors, with a well matchable waveform. CONSTITUTION:In case that redundant bits are added to an encoded signal, an error correction encoding circuit 3 generates and transmits a code block where uncorrectable errors can be detected. If the code block inputted to a reception terminal 9 includes errors in such degree that errors can be corrected, the code block is led to a decoding circuit 11 after error correction in an error correcting circuit 10 and is decoded to the original signal. Meanwhile, if the code block includes errors so much that errors cannot be corrected by the error correcting circuit 10, an error detecting circuit 14 detects this state to control a waveform processing circuit.

Title: Optical recording medium
Inventor: TAKI KAZUYA
IPC: G11B7/24085
Filed: 1991-09-27
Abstract: PURPOSE:To obtain the optical recording medium which is large in Kerr effect enhancement, exhibits excellent C/N, prevents the degradation in a push-pull signal for tracking, obviates an increase in crosstalks in spite of narrowing a track pitch and has high productivity. CONSTITUTION:A guide layer 16, a dielectric layer 18 and a recording layer 20 are laminated on a transparent substrate 12 and a part of the guide layer 16 is removed. Since the refractive index of the dielectric layer 18 is higher than the refractive index of the substrate 12, the Kerr effect enhancement is generated and the C/N is increased. The light for irradiation is partly shielded by the guide layer 16 and does not arrive at the adjacent recording region and, therefore, the crosstalks do not increase even if the track pitch is narrowed.

Title: Displayer of hot water storage tank
Inventor: ODA SOU
IPC: F24H1/18
Filed: 1983-12-23
Abstract: PURPOSE:To know the exchange time of a sacrificial anode bar exactly and quickly by a method in which when the sacrificial anode bar is consumed, the lead wire of a temperature sensor is short-circuited to the inside of the fitting hole of the sacrificial anode bar. CONSTITUTION:A fitting screw 12 to hold the upper end of a sacrificial anode bar 11 is screwed with a threshold hole 10. A temperature sensor-fitting hole 13 is provided in the upper end of the bar 11 in non-connected state with the internal space of a box 9, having a temperature sensor 14 inside. The sensor 14 may only contact with the upper end of the bar 11. One end of the lead wire 15 is thrust through the central hole 12a of the screw 12 and connected to the sensor 14, and an insulating cover 15a on one end side of the wire 15 is peeled off n the hole 13 to expose the conductive part 15b. When the bar is consumed during long-period use, water in the box 9 begins permeate into the hole 13 and comes to the exposed conductive part 15b of the wire 15, whereupon the part 15b is shortcircuited with the wire 15 to quickly lower signals (resistance values) to be transmitted to hot water temperature displayers 16 and 17 from the sensor 14. The exchange time of the bar 11 can thus be determined quickly and exactly.

Title: Optical pickup device
Inventor: MATOSAKI TOSHIYA
IPC: G11B7/09
Filed: 1988-10-03
Abstract: PURPOSE:To eliminate the necessity of a lead wire for power supply to a lens holder from an optical pickup device so as to improve the production efficiency and the reliability of the device by fitting a magnet to a lens holder side which goes to a mobile section and a coil which corresponds to the magnet to a base side which is a fixed section. CONSTITUTION:When an electric current is made to flow to a coil 7 for tracking in the direction ia, force is produced in a lens holder 2 in the direction fa and, when another electric current is made to flow to the coil 7 in the direction ib, force is produced in the holder 2 in the direction fb and rotates the holder 2 in the tracking direction (a). then, when an electric current is made to flow to a coil 8 for focusing in the direction ia, force is produced in the holder 2 in the direction fa and, when another electric current is mode to flow to the coil 8 in the direction ib, force is produced in the holder in the direction fb and slides the holder 2 in the focusing direction (b). Since a magnet 4 to which no power supply is required is fitted to the holder 2 which becomes a mobile section, no lead wire is required for power supply. Therefore, the production efficiency and the reliability of this optical pickup device can be improved.

Title: Electromagnetic interference wave measuring apparatus
Inventor: KANAI TAKESHI
IPC: G01R29/08
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To enable measurement of an electromagnetic interference wave from which extraneous noise is eliminated without using a radio wave anechoic chamber. SOLUTION: When an electromagnetic noise with directivity strong on the right side of the X axis is generated from an object 1 to be measured, this noise is measured by an extraneous noise detection antenna 1, in a specified time after measured by an EMI(electromagnetic interference) antenna 3, that is, 3.3 ns obtained by dividing a distance of 1m, between the EMI antenna 3 and the extraneous noise detection antennas 81 -86 by the velocity of 3×10<8> m of the electromagnetic wave. contrarily, when an extraneous noise comes from the right side of the X axis, the extraneous noise is detected by the extraneous noise detection antenna 81 and subsequently, sensed by the EMI antenna 3 in 3.3 ns. thereafter. This can distinctively determine whether the wave is the electromagnetic noise or the extraneous noise from the object 1 at a timing when the noise is detected by the respective antennas. After the processing involved, the EMI antenna 3 is moved by an EMI antenna position moving device to accomplish a series of measurements.

Filed: 1986-10-21
Abstract: PURPOSE:To extend the life of bellows by disposing an annular plate to the large-diameter part of the bellows and forming the bore thereof to the size which does not interfere with laser light and is smaller than the small-diameter part of the bellows. CONSTITUTION:Plural pieces of annular plates 9 are disposed at about every other one to the large-diameter part of the bellows 2. The bore size D1 of the plates 9 to be formed is determined larger than the outside edge size D0 of the laser light 8 and smaller than the size D2 in the small-diameter part of the bellows 2. The surface of the plates 9 is formed of Al, etc., and is subjected to a processing to absorb the laser light 8. The laser light 8 falls onto the plates 8 and the bellows 2 is protected even if the laser light 8 is deviated from the optical axis according to the above-mentioned mechanism. The laser light reflected from a work 7 falls similarly to the plates 9 and, therefore, the generation of a damage on the bellows 2 is prevented. The life of the bellows 2 is thereby extended.

Title: Wire type container inverter of rubbish collecting vehicle
Inventor: TANAKA TOSHIYUKI
IPC: B65F3/04
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To prevent cutting of a wire and damaging of a loading device caused by the entanglement of a part of the slack wire in the loading device during throwing in of the waste by providing a regulating means for regulating feeding in a wire slackening direction in the vicinity of a sieve and a guide on which the wire is wound. SOLUTION: During normal waste throwing-in work which does not use a container, a hook 57 is locked in a locking tool 2b fixed in the peripheral edge of a throwing-in port 2a. Since a first sieve 52 is moved up and down following the operation of a loading device, a wire 56 wound on the first and second sieves 52 and 54 is made slack, but its feeding in the slackening direction is regulated by each regulating member 8. That is, the feeding of the wire 56 in its slackening direction is regulated by each regulating member 8 serving as a resistor and thereby, the slackening of the wire 56 is distributed to the entire parts and the wire is made slack in a state like that shown in the drawing and thus extreme slackening of a part of the wire 56 and entanglement of the wire 56 with the loading device are prevented.

Inventor: NAMIKADO NAGAHIKO
IPC: H03L7/14
Filed: 1991-09-30
Abstract: PURPOSE:To prevent frequency fluctuation from being caused to a synchronizing clock signal even when a reference clock signal is momentarily interrupted. CONSTITUTION:A reference clock signal 1 desired of frequency synchronization is frequency-divided by a frequency divider circuit 2, the result is sent to a differentiation circuit 3, in which the signal is converted into a differentiation output signal 4 representing only a change point. The signal and a synchronizing clock signal 5 are fed to a frequency detection circuit 6, which digitizes a frequency difference and the result is fed to a protection circuit 8 as a comparison result signal 7. The protection circuit 8 changes its output after the comparison result signal 7 changes consecutively for, e.g. three times. Thus, even when the reference clock signal 1 is momentarily interrupted, the output of the protection circuit 8 is unchanged. The comparison result signal protected by the protection circuit 8 is inputted to a counter circuit 9, which changes a duty ratio of the output signal according to the signal representing the frequency difference.
