Title: Step-down dc/dc converter
Inventor: NAKAMURA MANTARO
IPC: H02M3/155
Filed: 1994-02-25
Abstract: PURPOSE:To reduce switching loss of a switching element at the time of ON/ OFF operation by constituting a DC/DC converter such that zero voltage or zero current switching is achieved for the switching element thereby decreasing the overlapping of voltage waveform and current waveform of the switching element. CONSTITUTION:When a main transistor(Tr) 2 feeding a current to a load 6 and charging a resonance capacitor (C) 8 with power supply voltage is turned OFF, current flow is deflected from the Tr2 to the C8 which is gradually discharged. Consequently, the voltage across the Tr2 increases gradually thus achieving zero voltage switching of the Tr2 at the time of turn OFF. When an auxiliary transistor Tr9 is turned ON prior to turn ON of the Tr2, power supply voltage is applied to a resonance reactor 10 during the conduction interval of a main circulation diode 3 and the current thereof increases iinearly from zero thus achieving zero current switching of the Tr9 at the time of turn ON.

Title: Screen display device
Inventor: YAMANOI GORO
IPC: H04N5/06
Filed: 1992-02-15
Abstract: PURPOSE:To prevent synchronous error at the time of switching a system from internal synchronism to external synchronism by providing a synchronous element synchronizing a synchronizing signal with an external synchronizing signal during an operation by means of the synchronizing signal generated in a device. CONSTITUTION:Horizontal/vertical synchronism generation counters 1 and 2 input a signal for synchronous signal generation and output H'SYNC inputs HSYNC and outputs VSYNC. NAND circuits 3a and 3b respectively input one shot pulses H'SYNC and V'SYNC by the output of FF4 and external HSYNC and VSYNC. FF4 inputs external VSYNC and an external synchronous selection signal. In the case of internal synchronism, the external synchronous selection signal becomes an L-level and VSYNC outputs an H-level at every two countings. Thus, the circuits 3a and 3b output the L-level by H'SYNC and V'SYNC and the counters 1 and 2 are reset so as to execute synchronism. Thus, the disturbance of synchronism at the time of switching internal synchronism to external synchronism is prevented.

Title: Direct current overlapping welding method
Inventor: HAYASHI YOSHIO
IPC: B23K11/06
Filed: 1986-02-13
Abstract: PURPOSE:To prevent the permanent magnetizing of a clamp part and to quicken and facilitate the operation by welding by alternately changing over the direction of the DC current with moving an electrode by turning it along the width direction of a steel plate. CONSTITUTION:The overlapping part of a steel plate 1 is pinched by pressing it with the upper electrode wheel 32a and lower electrode wheel 33a which travel by pressing from the upper part. In traveling the upper and lower electrode wheels 32, 33a, the power transmission is performed from a DC power source 31 via conductors 32b, 33b and deflection parts 32c, 33 so that the polarities of the upper electrode 32 and lower electrode 33 become reverse on each one time welding or plural times. The conversion of the polarity at this time is performed by switching the connection of the conductor 32b and 33b. In this way, the permanent magnetizing close to the clamp is prevented and the work can be performed quickly.

Title: Lens sheet
Inventor: KOBAYASHI YUKIO
IPC: G03B21/62
Filed: 1992-02-17
Abstract: PURPOSE:To obtain a lens sheet with the excellent adhesiveness between the transparent base material and UV curing resin and the transmittance of the screen of a video projection television improved and difficult to generate reflected light forming ghost by forming a Fresnel lens consisting of the UV curing resin on one side of the base material obtained by laminating sheets having different refractive indices. CONSTITUTION:The sheets having different refractive indices are laminated in >=2 layers to obtain a transparent base material 1. Although the thickness and material of the sheet to be laminated are not limited, a sheet with the light transmittance lowered by coloration, turbidity, etc., is undesirable. A Fresnel lens 2 consisting of an UV curing resin is formed on one side of the base material 1. When the lens 2 is formed on the other side having a higher refractive index, the signal injection side of a video projection television consists of the low-refractive-index plane, hence the reflectance of the interface is lowered when the signal is injected, and ghost is hardly formed.

Title: Light deflecting element
Inventor: MIURA AKIRA
IPC: G02F1/01
Filed: 1982-02-25
Abstract: PURPOSE:To enable high-speed action by heating one surface of an Al2O3 or BeO crystal body and by projecting laser light on the body parallel to the heated surface. CONSTITUTION:One surface of a crystal body 10 at the side of comb-shaped electrodes 21, 22 is heated by generating heat from the electrodes 21, 22, and the other surface 23 opposite to the electrodes 21, 22 is kept at a constant temp. When the body 10 is in the heated state, the interplanar spacing of parts of the body 10 close to the electrodes 21, 22 is wider, and the interplanar spacing of a part far from the electrodes 21, 22 is narrower. Accordingly, the parts close to the electrodes 21, 22 have a lower intermolecular density, and the surface 23 opposite to the electrodes 21, 22 has a higher intermolecular density. Since the refractive index of light passing through a transparent crystal body is higher at a part having a higher density, projected laser light is deflected toward the surface 23 opposite to the electrodes 21, 22 as shown by the solid line, and it emerges from the body 10.
