Title: Power supply circuit
Inventor: SUZUKI MASAO
IPC: H02J3/00
Filed: 1991-04-22
Abstract: PURPOSE:To prevent increase of cost due to replacement of fuse for each selected voltage or due to insertion of fuse into each winding by blowing out the fuse positively, regardless of the power supply voltage being selected, upon occurrence of abnormality in a power supply circuit which can switch the power supply voltage. CONSTITUTION:A power supply transformer 6 in a power supply circuit 1 has two primary windings 6P1, 6P2. A voltage selector 9 is switched to connect the primary windings 6P1, 6P2 in series or parallel thus selecting taps for obtaining various output voltages. A fuse F1 is inserted, as a main fuse, into a power supply input stage and a fuse F2 is provided on the side of one primary winding 6P2. When the primary windings 6P1, 6P2 are connected in series, the fuse F2 is blown out by an abnormal current to protect the circuit.

Title: Production of single crystal
Inventor: KAWACHI AKIHIKO
IPC: C30B13/22
Filed: 1978-09-21
Abstract: PURPOSE: To produce a high quality single crystal by setting a condensing ring around a melting zone in floating zone crystallization using infrared rays.  
     CONSTITUTION: Base material rod 3 and seed crystal 5 are placed in quartz tube 6, and melting zone 4 is formed. Most of infrared rays center on zone 4, yet infrared rays A, B are absorbed in rod 3 or crystal 5 to waste infrared energy. By setting quartz ring 7 around zone 4 infrared rays are efficiently centered on zone 4, and the width of zone 4 can be made as narrow as possible. Accordingly, zone 4 is thoroughly melted up to the central part, and a single crystal of large diameter can be produced. The thorough melting results in very little lattice defects in the single crystal.

Filed: 1990-05-07
Abstract: PURPOSE:To achieve a high-speed drive without reducing stopping accuracy by supplying current to a DC motor periodically in a direction which is opposite to a drive pulse by an inverse drive pulse for shorter time than a conduction time which is given to the DC motor by the drive pulse. CONSTITUTION:A conduction time which is given to a DC motor 5 by an inverse drive pulse is smaller than that given by a drive pulse, the DC motor 5 does not rotate in inverse direction, and the conduction time is set to a time width for restricting inertia of the DC motor 5 due to the drive pulse. A second NPN transistor 3 is turned on by allowing the inverse drive pulse to be fed to a control terminal B and conduction in inverse direction than the drive pulse is given to the DC motor 5 during a time width of the inverse drive pulse. As a result, periodical conduction in inverse direction allows inertia in positive direction of the DC motor 5 to be controlled.

Filed: 1991-05-23
Abstract: PURPOSE:To obtain the title apparatus constituted so as to arbitrarily set the variable range of a trigger level to the amplitude of an input signal and to obtain a non-triggered state. CONSTITUTION:The max. and min. values of the amplitude of an input signal are detected by peak detection means 3,4.

The slider voltage 19 of the potentiometer 18 is converted to a trigger signal from the input signal as a threshold value by a comparator 2. Since the max. and min. values of the amplitude are magnified, the variable range of a trigger level becomes 100% with respect to the amplitude of the input signal. By reducing the value of the resistor 16, the variable range of the trigger level becomes 100% or more with respect to the amplitude of the input signal.
