Title: Information recording medium and its reproducing device
Inventor: HIRATA ATSUMI
IPC: H04N5/928
Filed: 1987-11-20
Abstract: PURPOSE:To attain long time recording on an information recording medium such as a video disk, etc., by recording a video signal of the field number interleaved to an integral number ratio with respect to the normal field number of the TV standard system and a voice signal subject to time width compression in reverse ratio to the integer ratio. CONSTITUTION:When the video signal and the voice signal amplified to a prescribed level and subject to frequency modulation are supplied to the input terminal 1, a video demodulation circuit 2 sends the video signal. The video signal is written in a field memory 4 or 5 in the unit of fields while a switch 3 is switched alternately. The switch 3 is thrown to a fixed terminal (a) and when the video signal A is written in the field memory 4, the switch 3 is thrown to the position of a fixed terminal (c) and a video signal B is written in the field memory 5. Then the video signal A written in the field memory 4 is read succeedingly twice in the time of 2-field and the video signal B written in the field memory 5 is read consecutively three times in the time of 3-field. In this case, although the picture quality is deteriorated, there is not practical problem in the case of a moving picture or a small sized pattern.

Title: Electric wire and cable resistant to external damage
Inventor: ITO KAZUMI
IPC: H01B7/17
Filed: 1989-11-14
Abstract: PURPOSE:To improve external damage resistance and abrasion resistance, and also prevent lowering of flexibility by applying liquid hardening resin on the cover of an electric wire and cable with the thickness of a given value to be hardened. CONSTITUTION:Liquid hardening resin is applied to the cover of an electric wire and cable so as to have a thickness of 20-100mum to be hardened. Hardening resin, enabling formation of a coating film having flame retardancy and hard quality such as liquid polyurethane, etc., having an oxygen index of 25 or more, is suitable for liquid hardening resin. External damage resistance is insufficient when the thickness of the coating film is thinner than 20mum, and adversely the coating film formation becomes difficult when its thickness is thicker than 100mum and also flexibility worsens. This causes the external damage resistance and abrasion resistance to be imporved and the coating film has a thin thickness of 20-100mum, consequently flexibility and other physical characteristics basic to an electric wire and cable are not detracted, and also an outer diameter can be made small.

Title: Cold-cathode tube lighting inverter
Inventor: KUMASAKA KATSUNORI
IPC: H05B41/24
Filed: 1998-10-16
Abstract: PROBLEM TO BE SOLVED: To improve the mobility in power source input of a cold-cathode tube and the lighting property at low temperature thereof by detecting the current carried to the cold-cathode tube to which a lighting voltage is inputted, controlling the oscillating frequency of a voltage control oscillating circuit, and protecting a piezoelectric transformer for lighting voltage in conformation to the change of load impedance. SOLUTION: When a DC voltage Vcc is inputted to an inverter 10, the secondary output of a piezoelectric transformer 11 is applied to a cold-cathode tube 50, and a cold-cathode tube current detecting circuit 15 detects the current as voltage signal. The detected current is fed back to a voltage control oscillating circuit, in which the oscillating frequency is controlled so as to be close to the resonance frequency of the piezoelectric transformer 11. When the step-up ratio of the piezoelectric transformer 11 is raised, and the cold-cathode tube 50 starts to discharge, the current is suddenly increased, and the oscillating frequency of the voltage control oscillating circuit 12 is stabilized in the resonance frequency of the piezoelectric transformer 11.  A primary current of the piezoelectric transformer 11 is monitored by a protecting circuit 30, and when an excessive current is detected, a stop signal is outputted to temporarily stop the output of the voltage control oscillating circuit 12.

Abstract: PURPOSE:To improve the reliability of a remote channel system by detecting the trouble of a long distance interface at an early time in a central unit and a remote channel device. CONSTITUTION:In the remote channel device 5, at the time of an idle state, an instruction control part 54 instructs the transmission of an idle frame to an optical interface control part 51 at a determined time interval to examine whether a response frame from an optical channel device 3 is received or not within a prescribed time.

Title: Pincushion distortion correction circuit
Inventor: HARA NOBUAKI
IPC: G09G1/16
Filed: 1988-11-25
Abstract: PURPOSE:To make an indicator easily adjustable so that the indicator can stand variation of temperature, etc., and can be improved in reliability by providing a means which finely adjusts pincushion distortions produced on a CRT in a digital way. CONSTITUTION:An S-shape characteristics conversion circuit 1 converts data into data roughly having S-shape characteristics so that pincushion distortions produced on the displaying section of a CRT can be reduced. Namely, when tooth-shaped wave digital signals are inputted to the circuit 1, the circuit 1 gives the S-shape characteristics to the signals and signals having S-shaped characteristics are outputted. On the other hand, an S-shape factor storing section 3 inputs the tooth-shaped wave digital signals and, at the same time, outputs one correction pattern output of several kinds of correction patterns in accordance with the instruction of a switch circuit 4. An adding circuit 2 adds the outputs of the circuits 1 and 3 to each other and obtains finely adjusted output signals. Therefore, this pincushion distortion correction circuit can be adjusted easily and can stand temperature variation and, accordingly, improve in reliability.

Title: Absorber for absorption freezing cycle
Inventor: ODA YOSHIYA
IPC: F28D3/02
Filed: 1990-10-31
Abstract: PURPOSE:To cause absorption liquid to uniformly flow down from an entire circumference of an opening of a heat transmitting pipe and to improve a contact efficiency with refrigerant by a method wherein vibration is given to an indoor absorption liquid. CONSTITUTION:As an ultrasonic vibrator 30 is operated to apply an ultrasonic vibration to absorption liquid 3 within a chamber 4, waves are generated at a surface of the absorption liquid 3. When the absorption liquid 3 flows over an edge of an opening 21a, vibration is added to it. As a result, the absorption liquid 3 is not locally concentrated at one circumferential edge, that is, the absorption liquid 3 spreads over its entire circumference and falls. In addition, vibration is also transmitted to the absorption liquid 3 flow down at the inner surface of the heat transmitting pipe 21, thereby the flowing down absorption liquid 3 is vibrated and expanded to the inner surface of the heat transmitting pipe 21. With such an arrangement, a contacting efficiency of the water vapor with the absorption liquid is improved and then a concentration of the absorption liquid 3 is uniformly promoted.
