Title: Motor driving circuit
Inventor: YOSHITOMI TETSUYA
IPC: H02P7/288
Filed: 1991-03-22
Abstract: PURPOSE:To reduce the power consumption without the consideration of the current amplification factor of the first output transistor between a motor and a power source and that of the second output transistor at the other end of the motor, by providing a third transistor current-mirror-connected with the first output transistor in addition to the first and second output transistors. CONSTITUTION:A transistor 8 and an output transistor 2 are current-mirror- connected. And the base current IR3 of an output transistor 3 becomes the sum of the base current of the output transistor 2 and the collector current of the transistor 8, in the case of supplying driving current IO to a motor 1. When the current amplification factors of the output transistors 2, 3 are represented by hFE1 and hFE2 respectively here, their relation is set so as to satisfy hFE1>>hFE2. But even when it becomes hFE1>hFE2, a sufficient driving current can be flown into the motor 1. And when the driving current IO is flown into the motor 1, the current IR3 needed for the output transistor 3 has only a parameter of IO, so the current value becomes corresponding to the driving current IO of the motor 1.

Title: Semiconductor laser device
Inventor: WATABE YASUHIRO
IPC: H01S5/00
Filed: 1991-03-22
Abstract: PURPOSE:To improve heat dissipation and productivity by composing a heat sink provided between a semiconductor laser element and a metal block of Si or Mo series, and forming a thin film on a surface of the block or the element. CONSTITUTION:Since a heat sink 11 made of a thin film is formed on a surface 12 of a metal block 7 or a surface 19 of a semiconductor laser element 1 thereby to form the sink 11 thin, its heat resistance value is reduced, and a temperature rise of the element 1 is reduced. Further, since a material of Si or Mo series of the material of the sink 11 has substantially the same thermal expansion coefficient as that of the element 1, its thermal stress distortion is small, and a material of Si series and particularly an amorphous Si is easily formed as a film at a relatively low temperature. Thus, heat dissipating and productivity are improved.

Filed: 1991-03-22
Abstract: PURPOSE:To detect magnetic resistance change and to enable measurement of magnetic flux by arranging electrodes at both ends of a conductive body or a semiconductive body of two-dimensional layer structure, which has Anderson localization effect, and by measuring change of amperage flowing between the both electrodes. CONSTITUTION:A magnetism measurement part is constituted of patterns 2x, 2y and 2z and electrode terminals 3x, 3y and 3z, each four of which are arranged to the terminals, and shows Anderson localization effect. A sample S is attached to a sample attaching part 4, to measure resistance value of each flux meter prior to charging of magnetic field. After that, electric current is fed to a superconductive magnet 5 and magnetic field is charged to the magnet in order to measure resistance changing rate of the terminals 3x, 3y and 3z in case that the magnetic field is changed. Since the resistance has a dependency to angle of the charged magnetic field, angle of a sample holder 1 is regulated by moving a pole 6 so that the magnetic resistance may be the maximum or the minimum, prior to commencement of actual measurement. In this way the resistance changing rate is measured and thereby magnetic flux can be measured.
