Patent JP-H08168258-A (JP)
Title: Three-phase high-power-factor converter
Inventor: CHICHIKAWA TAKASHI
IPC: H02M7/06
Filed: 1994-12-08
Abstract: PURPOSE: To control a three-phase high-power-factor converter at a high power factor without producing any switching loss at the time of switching operation by supplying electric power from a three-phase AC power source to a load connected in parallel with a smoothing capacitor as a sine wave which is improved in power factor. CONSTITUTION: Since the electric currents of reactors Lr1 and Lr2 are made discontinuous and zero current switching (ZCS) operations are performed at the time of turning on first and second switching elements Tc1 and Tc2, no switching loss occurs. In addition, since no voltage is applied across the elements Tc1 and Tc2 and the elements Tc1 and Tc2 perform zero voltage switching (ZVS) operations while the voltages applied across the elements Tc1 and Tc2 are zero, no switching loss occurs until a coupling capacitor Cc is charged.

Title: Laser processing device
Inventor: IEHISA NOBUAKI
IPC: B23K26/00
Filed: 1988-12-29
Abstract: PURPOSE:To prevent the damage of optical parts and to prevent the processing defect of a work by detecting the increase of a monitor value by an abnormality detecting means, upon the increase of the above-mentioned value above the prescribed value, and stopping the operation of a laser oscillator and the movement of the work and nozzle, and then displaying an alarm on a display device. CONSTITUTION:Reflected laser light 11 is returned through a condenser lens 9 and a bender mirror 8 from an output mirror 6 again into the oscillator. The optical parts are damaged by the abnormal increase of the laser power in the oscillator when the level of the peak value of the reflected laser light is high. Good processing is not possible in the state in which the level of the reflected laser light is high. The level of the reflected laser light 11 is monitored by a reflected light detecting means. The monitor value rises above the prescribed value when the abnormal reflection arises and, therefore, this increase is detected by the abnormality detecting means. The operation of the laser oscillator and the movements of the work and the nozzle are simultaneously stopped and the alarm is displayed on the display device. The work loss is minimized in this way and the processing efficiency is improved.

Title: Stereoscopic display device
Inventor: TETSUYA SHINJI
IPC: G03B35/24
Filed: 1989-12-25
Abstract: PURPOSE:To assure natural and stable steroscopic viewing by providing a diffusion layer on the protective glass of a display, bringing a lenticular lens sheet into tight adhesion with the surface of the diffusion layer and registering the focal plane of the lenses of the sheet with the position of the diffusion layer. CONSTITUTION:The light emitted from light emission regions 15 of color filters 13 have the spread larger than the picture element size of the filters 13. The thickness of the upper protective glass is so determined that the spread covers the position approximately spreading to the picture element pitch. The diffusion layer 20 is provided above this glass. The picture elements (light emitting regions 15) of the color filters 13 are projected and the light is emitted without spacings in the diffusion layer 20. As a result, the non-light emitting regions do not exist. Blank stripes are not generated if the display device is so designed that the position of the diffusion layer 20 exists approximately at the focal plane of the lenses of the lenticular lens sheet 30. The non-light emitting regions 143 spread similarly but do not emit light and, therefore, there is no influence to be exerted on the images.

Title: Method for repairing color of coated product
Inventor: TANAKA HIROKAZU
IPC: B05D7/24
Filed: 1999-11-25
Abstract: PROBLEM TO BE SOLVED: To provide a method for repairing color of a coated product, in which someone is enabled to repair color easily and cleanly at a short time without unevennesses. SOLUTION: In a piece 10a stuck with a surface decorative material 12 having extremely thin color tone in comparison with the other piece 10, a coloring agent, in which acidic dye containing a metal is dissolved in a solvent, is thinly applied on a paint film 13 by a brush. At a point of time when the coloring agent applied on the paint film 13 is dried to such a degree that the coloring agent is not stuck to a finger, the coloring agent is wiped off by waste containing a solvent having dissolving performance lower than the solvent used in the coloring agent for the acidic dye containing the metal. Therefore, a part of the coloring agent applied on the paint film 13 is removed and at this time the applied unevennesses of the coloring agent are simultaneously removed and such a state is obtained that the piece 10a is uniformly colored by the coloring agent.  Further, when the piece 10a is not sufficiently colored by a repairing work of one time, the similar repairing work is repeated until the piece 10a becomes color tone of nearly the same degree as the color tone of the piece 10 in the periphery.
