IPC: G02F1/133
Filed: 1995-10-30
Abstract: PROBLEM TO BE SOLVED: To increase a driving margin and a temperature margin and enable an analog gradational display of practical level without making a driving circuit complicated or increasing the cost by suppressing the number of analog gradations low. SOLUTION: A display which uses liquid crystal(FLC) is so constituted as to make a display of >=4 gradations in one pixel PX by arranging the FLC between a couple of substrates 1a and 1b having electrodes 22a and 22b on their opposite surface sides. For each pixel PX, the data electrode 22a is divided into an electrode A and an electrode B, whose division area ratio is controlled corresponding to the number of display gradations. When this FLC display is driven, the divided electrodes A and B are driven independently of each other.

Inventor: SHIN ARIAKE
IPC: B41M5/26
Filed: 1990-11-10
Abstract: PURPOSE:To obtain a predetermined signal characteristic even when the pre- groove shape of a light pervious substrate slightly changes by measuring the shape dimension of the pre-groove of the light pervious substrate and thickly forming a dye layer as compared with such a case that said dimension is small. CONSTITUTION:A light pervious substrate 2 wherein the depth or width of a pre-groove is measured is clamped to the spindle 13 of a spin coater 11 by a feed arm 4 and rotated by a motor 12. At the point of time when the light pervious substrate 2 reaches steady rotation after the motor 11 is started, a dye material is supplied to the light pervious substrate 2 from a coater nozzle 14. Whereupon, the dye material is shaken off from the substrate 2 by centrifugal force and the uniform coating film of the dye material is formed on the surface of the substrate 2. At this time, the depth and width of the pre-groove of the light pervious substrate 2 measured by an operator 9 are preliminarily inputted to a controller 10 and the motor 12 is rotated on the basis of the rotary pattern determined based on the measured depth and width.

IPC: E04B1/36
Filed: 1988-12-01
Abstract: PURPOSE:To improve vibration-proof capacity and durability by layering alternately a plurality of rigid sheets and rubber elastic sheets, and by making the elastic sheets unfixed, at least at their peripheral parts, to the rigid sheets.

Abstract: PURPOSE:To sense an electron beam image and an optical image simultaneously by furnishing No.1 sensing means, which is to sense the reflex light from a specimen through an optical lens, and No.2 sensing means to sense an electron beam image through an optical filter after the electron beam from the specimen is cast on a fluorescent plate. CONSTITUTION:A reflex optical system is incorporated in a magnetic objective lens 3, and a beam in appropriate wavelength range, for ex., visible light, is irradiated on a specimen 5. The optical image is sensed from the reflected light, and electron beam sensing uses a fluorescent plate 7 which emits light with a beam in other wavelength range than the illuminating light, for ex., ultraviolet ray, and does not emit light with a light belonging to the mentioned wavelength range of illuminating light, and in front of a photo-electron doubler tube 10, an optical filter to block a light in the wavelength range of the mentioned illuminating light is inserted. Thereby illumination for obtaining optical image does not hinder sensing of electron beam, that enables simultaneous sensing of optical image and electron image without requiring movement of the specimen to a great extent.

Title: Feeling improvement method for electronically controlled operation lever
Inventor: KOBASHI YUJI
IPC: B60K20/02
Filed: 1998-10-27
Abstract: PROBLEM TO BE SOLVED: To operate a transmission so as to reflect a worker's sense and to improve an operation feeling by detecting the manipulated amount of a travel operation lever with a position sensor, and varying speed increase for the manipulated amount depending on the detection result of the sensor when calculating the target speed ratio of a travel vehicle. SOLUTION: When a speed ratio instruction lever is operated by a worker, a position sensor detects the manipulated amount of the lever, and sends the detection result to a controller. In this case, the controller calculates the target speed 222 of a travel vehicle from an input value 221, and a relationship between the input value 221 and the target speed 222 is changed in several zones separately on the basis of the input value 221 from the position sensor. When the input value 221 is in a low speed zone, the gradient of the relationship 223 is small and this gradient gradually becomes large according to a change to an intermediate speed zone and a high speed zone. Then, a calculated target value 222 is outputted and a hydraulic pump motor is thereby controlled. According to this construction, an operation feeling fitted to a worker's sense is provided.
