Title: Inverter circuit
Inventor: SUZUKI SADANORI
IPC: H02M7/48
Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To provide an inverter circuit, capable of quickly and reliably starting a capacitive load or the like. SOLUTION: A DC/AC conversion circuit 1 converts the output of a DC power source into an AC, in accordance with the instruction from a control circuit 10. A control circuit 10 determines the ratio between a conducting period and a stop period of the DC/AC conversion circuit 1, so as to keep the effective value of the output voltage constant based on the output voltage of the DC power source. If an output current exceeds a predetermined value, a current- limiting circuit 4 notifies it to the control circuit 10. If the output current exceeds a predetermined value, the control circuit 10 increases the ratio of the conducting period of the DC/AC conversion circuit 1.

Abstract: PROBLEM TO BE SOLVED: To provide a saturable reactor having a function as a current limiting element, and also provide a power supply equipment for pulse laser using this reactor. SOLUTION: This saturable reactor has a magnetic core 1 which is a saturable one, a primary winding 2 wound around the magnetic core 1, an auxiliary winding 3 also wound around the magnetic core 1, and a source of current for causing current of such a value as to exceed the one required for transiting the magnetic core 1 from a non-saturate state to a saturated state to flow in the auxiliary winding 3 by means of the auxiliary winding 3 itself. When current i2 is caused to flow in the primary winding 2, the magnetic core 1 becomes a low inductance state.  When current i1 is caused to flow in the primary winding 2, the magnetic core 1 exhibits a saturated state and becomes a low inductance state, keeping that state to a specified current value, and then becomes a non-saturated state when the current value exceeds a specified value and then is transited into a saturated state again when a voltage-time product becomes a specified value.

Filed: 1992-07-27
Abstract: PURPOSE:To improve the corrosion resistance of a bearing by constituting a part from a metal having the larger ionization tendency than that of the base material of the orbital wheel of a roller bearing. CONSTITUTION:The both edge inside diameter part of an outer race 2 and the both edge outside diameter part of an inner race 1 are constituted of the metal parts 5 and 6 having the larger ionization tendency than that of the mertensite group stainless steel as base material. Further, these metal parts 5 and 6 are formed by integrally fixing a ring body made of the base metal such as zinc and lead onto the base material, and the inside diameter side of the metal part 5 and the outside diameter side of the metal part 6 are oxposed to the bearing inside space. Since a part except the rolling surface of an orbital wheel is constituted of the metal having the larger ionization tendency than that of the base material of the orbital wheel, a battery is formed between the metal parts 5 and 6 and the base material, and the metal parts 5 and 6 form anodes and the base material part forms a cathode. When this bearing is placed in the corrosive environment, the metal parts 5 and 6 as sacrifice anodes positively react with the reactive substance in the environment, and the generation of corrosion on the rolling surfaces 1b and 2b is prevented.

Title: Thermo-writing liquid crystal light valve
Inventor: KATO YUJI
IPC: G09F9/30
Filed: 1985-09-09
Abstract: PURPOSE:To form a thermo-writing liquid crystal light valve which is high in displaying contrast and resolution, by shifting the 2nd light absorbing film from the 1st light absorbing film by one picture element. CONSTITUTION:The light absorbing film 5 of the light projecting side is constituted under a one-picture element shifted condition against the light absorbing film 8 formed on the writing light side. By providing a glass base plates and resin films having a smaller heat conductivity than the light absorbing films have and constituting the resin films and light absorbing films at every second picture element, escape of the heat produced in the light absorbing films in the direction of the base plate and in-plane direction is decreased and the produced heat is effectively used for raising the temperature of liquid crystal. Therefore, the scattering kernel is formed deeper and displaying contrast is improved. Moreover, picture elements of 10mum diameter are written and resolution is improved even if the diameter of a writing laser beam is expanded to 12mum, when, for example, the light absorbing films and resin films are formed at intervals of 10mum, because expansion of the heat in the in-plane direction is decreased.

Title: Magnetic recording and reproducing device
Inventor: KANI TETSUO
IPC: G11B5/027
Filed: 1984-09-25
Abstract: PURPOSE:To remove wow and flutter components from a reproducing signal by recording a signal obtained by modulating an input signal and a signal obtained by modulating the phase-inverted signal of the input signal on adjacent tracks on a magnetic tape, and subtracting their reproducing demodulated signal from each other and outputting the difference signal. CONSTITUTION:An FM modulating circuit 22 in a recording system imposes FM modulation according to an input audio signal AIN and a recording head 24 records the signal on a track TR1 formed on a magnetic tape lengthwise. Further, the phase-inverted signal AIN is FM-modulated by an FM modulating circuit 32 in a recording system 30 and recorded by a recording head 34 on TR2 adjoining to TR1. The signal recorded on TR1 is reproduced and demodulated by a reproducing system 40 and the signal recorded on the TR2 is reproduced and demodulated by a reproducing system 50. An output circuit 60 subtracts the signals demodulated by the reproducing systems 40 and 50 from each other and outputs the resulting signal. Thus, wow and flutter components are removed from the reproducing audio signal.

Title: Information recording/reproducing device
Inventor: TAKANASHI RYOYU
IPC: G11B19/06
Filed: 1990-07-27
Abstract: PURPOSE:To attain high accuracy of the device without lowering the accuracy of a recorded information read signal by providing a reproducing head with an index signal generating part for adding an index signal to a video signal of each read line on a recording medium respectively. CONSTITUTION:This index signal generating part 7c is disposed in a prescribed position slightly toward the left side from the left end of a recording and reproducing area of a medium 2. Consequently, since the index signal corresponding to a nonmasking part of the generating part 7c is generated whenever main scanning is performed, an output signal of a photodiode in this device 1 is added with the index signal before starting the video signal of each read line at prescribed timing respectively. Then, the timing between the video signal and the index signal is maintained in a prescribed relationship, and hence no deviations take place in the timing of the video signal and between address signals. Consequently, the recorded information read signal becomes highly accurate.
