Title: Optical head
Inventor: ANDO HIDEO
IPC: G11B11/10
Filed: 1985-03-27
Abstract: PURPOSE:To detect the large degree of optical modulation due to presence/ absence of pits on a medium by providing a light extracting member near the condensing point of a reflected beam from the storage medium to detect only the light near the optical axis of the optical beam. CONSTITUTION:An aperture 35 as the light extracting member is provided near the condensing point of a projection lens 34 which condenses an optical beam L21 reflected from an information storage medium 10, and only the light near the optical axis of the optical beam out of the light passing the aperture 35 is detected by a photodetector 36. In this case, the diameter of a hole 35a is selected properly to receive a <=1/1 quantity of the overall quantity of light. Thus, the bad influence of the reflected light, which is caused because the diameter of the minimum spot of the optical beam is larger than the pit diameter, is eliminated to detect the large degree of optical modulation due to presence/ absence of pits.

Title: Projection type liquid crystal display device
Inventor: HAMADA TETSUYA
IPC: G03B21/00
Filed: 1990-03-14
Abstract: PURPOSE:To eliminate flicker of a display picture by making the light from a light source incident on two liquid crystal panels and applying the same data to these two liquid crystal panels with different polarities to modulate the light and synthesizing two modulated light on a screen by an optical synthesizing means to display the picture. CONSTITUTION:The light from a light source 1 is made incident on two liquid crystal panels 2 and 3, and the same data is applied to these two liquid crystal panels with different polarities to modulate the light, and two modulated light are synthesized on a screen 5 by an optical synthesizing means 4 to display the picture. That is, modulated light transmitted through two liquid crystal panels 2 and 3 are synthesized in the same position on the screen 5. Consequently, the same synthesis result is always obtained though the change of the display data signal characteristic is different between positive and negative voltage application modes because of the change of TFT or liquid crystal due to the rise of temperature of liquid crystal panels. Thus, the occurrence of flicker due to the rise of temperature of an active matrix type liquid crystal display panel is suppressed whichever coloring the display has.

Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of sterilization by mixing a water supplied from a water source with ozone gas, separating ozone gas contained in the ozone water to take out the purified water and removing impurities contained in the purified water. SOLUTION: The water passing through a water supply pipe line 4 and ozone gas supplied from an ozone gas supply pipe line 15 are mixed with each other while being compressed by a mixing pump 6, and the ozone water is discharged to the ozone aeration tank 7. Since the water and ozone gas are mixed with each other while being compressed by the mixing pump 6, ozone becomes fine bubbles, diffused in the water and efficiently dissolved in the water, and simultaneously organic materials in the water is made into low molecule. Further, since various bacteria contained in the water filtered by the prefilter 5 are sterilized, the safety as drinking water is improved. Also since the mixing pump 6 being the gas-liquid mixing means is used, this device is miniaturized.

Abstract: PURPOSE:To enable the pump characteristics to be set out arbitrarily while permitting the device to be very simple in construction by controlling orifices according to the differential pressure in a restricted passage provided between the circumference of a sleeve placed on a union and the internal surface of a housing hole. CONSTITUTION:When the speed of rotation of a pump 6 is gradually increased, the discharge rate of flow increases, and a spool valve 3 is caused to move to the left by the differential pressure across a fixed orifice 4d and orifices 4g, 4h, and accordingly, the rate of flow supplied to power steering apparatuses P, S is kept nearly constant.
