Inventor: NUMATA YOSHIYUKI
IPC: C03B11/00
Filed: 1988-11-30
Abstract: PURPOSE:To obtain the mold forming an optical glass element of high preciseness which has high strength in high temp. and is free from the adhesion with molten glass in high temp. and the surface of which is the mirror surface difficult to be oxidized by coating the forming surface of the base material of mold brought into contact with the glass raw material with the thin film consisting of tantalum oxide. CONSTITUTION:Sintered alloys or ceramics are used for the base material of mold, and the forming surface brought into contact with the glass raw material is coated with the thin film of 0.1 to 1.5mum thickness of tantalum oxide (Ta2O5), and the target forming mold is obtained. By using this forming mold, the press forming of high preciseness for optical glass is allowed to be carried out. This mold has a long life because the deterioration of the surface layer is small which results in remarkable decrease of the number of mold exchanging times and enables the mass production of precise optical glass elements. By using this mold, the productivity is improved and the production cost is decreased.

Title: Optical measuring apparatus
Inventor: YACHI AKIFUMI
IPC: G01N21/00
Filed: 1991-11-21
Abstract: PURPOSE:To obtain an optical measuring apparatus by which the effect of the reflected light from the surface of a diffused body on the measurement can be removed. CONSTITUTION:The surface off an organism (a) which is an object to be measured is lit with a linearly polarized light source 13 through a perforated mirror 4. The image of the returned light from the direction of the organism is focused on the light receiving surface of a photodetector 5 through a lens 1, the perforated mirror 4 and a lens 2. The contents of the amounts of light reaching the photodetector are the reflected light from the surface of tissue, the multiple scattered lights at the tissue and the scattered light from the erythrocyte in blood vessels. A polarizer 6 is provided in front of the photodetector 5 so that the polarizing direction crosses the direction of the polarized component of the reflected light from the surface of the organism at a right angle. The reflected light from the surface of the organism keeps the direction of the linearly polarized light from the linearly-polarized light source 13. Therefore, the reflected light component from the surface to be measured as the noise is removed with the polarizer 6. Only the light component reflecting the phenomenon in the object to be measured of a diffused body can be received.

Abstract: PROBLEM TO BE SOLVED: To always hold the electrification potential of a photoreceptor at a fixed value regardless of environmental conditions such as temperature and humidity. SOLUTION: A correction mode executing means D executes a correction mode in which voltage previously set by a voltage applying means A is applied on an electrifying member while turning the photoreceptor, and applied voltage on the electrifying member which is required to make the electrification potential a target value is calculated based on the value of the electrification potential detected by an electrification potential detecting means at that time so as to correct an applied voltage correction rule in accordance with the detected temperature by a temperature detection means B by a voltage correction means C based on the calculated result.  It is desirable to execute the correction mode when the detected temperature by a roller temperature detection means detecting the surface temperature of a fixing roller is equal to or under the previously set temperature or every time the previously set number of image forming cycles is attained.

Title: Disk driver
Inventor: KOIZUMI SHIGEKI
IPC: G11B17/028
Filed: 1990-11-14
Abstract: PURPOSE:To reduce in thickness a disk driver by engaging a drive pin lever with a disk in a simple structure not necessary for a roller to drive it. CONSTITUTION:A driving pin arm 8 is rotatable at a driving pin 6 of one end with the shaft 7a of a flange 7 as a center. When a disk 1 is placed on the flange 7 by engaging the chucking hole 3 of a medium hub 2 with a rotary shaft 5, the pin 6 is pressed down, a thin part 8a is deformed, and the hub 2 is attracted to the flange 7. When the shaft 5 is rotated and a head holds the disk 1, the pin 6 is engaged with a positioning hole 4, the centering force F1 of the hub 2 and the repelling force F of the driving force F2 of the hub are operated at the arm 8, and the pin 6 is not deformed. Thus, a disk driver can be further reduced in thickness.

Title: Liquid crystal display device
Inventor: HAZAMA YOSHIKAZU
IPC: G02F1/133
Filed: 1991-10-25
Abstract: PURPOSE:To eliminate shading which is generated at the lower part of a liquid crystal display unit caused by a field inversion driving system by using a simple circuit. CONSTITUTION:A counter circuit 1 is reset with a vertical clock phiVST and counts a horizontal clock phiHST. The counter circuit 1, therefore, indicates the number of vertical lines. A D/A converter 3 converts the number of lines into an analog signal, which is outputted as a control bias signal CB to a gain- controlled amplifying circuit 7. The gain-controlled amplifying circuit 7 amplifies a driving input signal Vsig with the gain corresponding to the control bias signal CB and outputs an LCD panel driving signal Vsig. The control bias signal CB increases with the number of lines, so the amplitude of the LCD panel driving signal Vsig increases toward the lower part of an LCD panel 10. Consequently, a decrease in the amplitude of the LCD panel driving signal Vsig at the lower part of the LCD panel 10 is compensated to prevent the shading.
