Patent JP-H0254479-A (JP)
Title: Optical head travel guiding mechanism
Inventor: KOBAYASHI SENYA
IPC: G11B21/02
Filed: 1988-08-18
Abstract: PURPOSE:To prevent play from being generated between a roller and a travel rail by applying repulsion or an attractive force between a linear motor magnet fixed on the main body device side of an optical disk device and a magnet or a magnetic material on an optical head side as a force to press the optical head downward, and pressing the roller to the travel rail side. CONSTITUTION:When an optical head travel control current flows on a linear motor coil 11, a travel driving force in a travel direction (direction of arrow head A) is generated by an electromagnetic force applied between the linear motor coil 11 and a linear magnet 13, and the optical head 3 is supported and guided accurately along the travel rail 1 on one side by a bearing 4, and simultaneously, the roller 5 is moved rotatably on the travel rail 2 on the other side, then, the head is traveled between the inner periphery and the outer periphery of a disk. At the time of traveling the optical head, the magnet 14 on the optical head 3 side and the linear motor magnet 13 are repulsed with each other since their N poles are neighbored to each other, and the optical head 3 receives a downward force by the repulsion, then, the roller 5 is pressed on the rail 2. Therefore, the roller 5 is moved rotatably keeping contact with the travel rail 2 even when the optical disk device is used perpendicularly, which prevents the optical head 3 from being inclined against the plane of the disk.

Title: Bias circuit for amplifier
Inventor: ISHIGURO KAZUHISA
IPC: H03F1/34
Filed: 1985-09-19
Abstract: PURPOSE:To supply a bias voltage without causing crosstalk or mutual interference to plural amplifier circuits in an IC by using negative feedback action of a negative feedback amplifier section so as to lower sufficiently an output impedance of the negative feedback amplifier section. CONSTITUTION:Since much negative feedback (>=60dB) is applied to a differential amplifier circuit 22, the emitter voltage of an output transistor (TR) 23 is very stable. Since the output impedance of a negative feedback amplifier section 21 is a very small value, an AC signal caused at the emitter of the n-th buffer TR 26 is not transmitted to the emitter of the 1st buffer TR 25, then the crosstalk between biased amplifier circuits is improved and mutual interference is avoided. Further, voltage obtained at the 1st and n-th output terminals 31, 32 and the voltage obtained at an output terminal 33 are made equal to cancel the problem of an offset.

Filed: 1990-08-03
Abstract: PURPOSE:To reduce communication cost by transmitting the only changed broadcasting data from respective local area networks to be transmitted through a communication network to the other local area network. CONSTITUTION:A self system broadcasting data transmission means 300 compares the broadcasting data transmitted from each terminal equipment 11 stored in a self system local area network 1 with the broadcasting data held in a broadcasting data holding means 200.

Title: Superconduction thermometer
Inventor: TAMADA NORIJI
IPC: G01K7/00
Filed: 1986-09-03
Abstract: PURPOSE:To obtain a thermometer which is tolerant to noises and has high reliability and temperature measurement resolution by providing a superconductor and a means which impresses a magnetic field to the superconductor. CONSTITUTION:The superconductor M is placed in a superconducting coil C for magnetic field production and the constant magnetic field HB which is produced by a bias magnetic field generating coil B or permanent magnet is impressed to the superconductor M in the opposite direction from a magnetic field produced by the coil C. In this case, the magnetic field HB is larger than the critical magnetic field HC of the superconductor M. Thus, when the bias magnetic field is impressed to the superconductor M, the magnetic field produced by the coil C cancels the bias magnetic field and the superconductor M holds itself in a normal conductive state and indicates finite electric resistance rn unless the composite magnetic field becomes smaller than the critical magnetic field HC of the superconductor M. Here, the resistance rn is larger than a resistance R2. At this time, the critical magnetic field HC of the superconductor M varies with temperature, so the current when the composite magnetic field reaches HC depends upon the temperature. Therefore, the temperature is measured is terms of an oscillation frequency.
