Title: Electrostatic latent image developing device
Inventor: MIZUNO HIROSHI
IPC: G03G15/09
Filed: 1988-03-08
Abstract: PURPOSE:To stably and certainly bring a thin film member into contact with a device roller by pressing the thin film member against the roller by means of a guide member having a prescribed pressing angle. CONSTITUTION:A thin film member 11 is closely adhered to the peripheral surface of a drive roller 10 and the angle of a guide member 9 provided on the surface facing a photosensitive drum 100 is set to 180-250 deg.. Moreover, a layer thickness regulating member 12 is fitted to the back of a supporting member 6 provided above the drive roller 10 and comes into contact with the thin film member 11 at the leading edge section. Since the thin film member 11 having a longer circumferential length than the drive roller 10 has is provided against the roller 10 in such a way, a space is formed between the member 11 and roller 10 in the section facing the photosensitive drum 100. Therefore, the thin film member covering the space 11 can be brought into contact softly and stably with the surface of the drum 100 with a very low pressure-contacting force in the developing area and, at the same time, the layer thickness regulating member 12 can be pressed against the roller 10 with a strong pressing force.

Title: Flow or pressure controller for hydraulic circuit
Inventor: KAYANUMA KIYOKAZU
IPC: F15B11/04
Filed: 1979-05-02
Abstract: PURPOSE: To enable closed loop control of flow or pressure by a hydraulic system which eliminates the necessity of strict control of working oil against contamination and which prevents rapid responsiveness by providing a proportional flow control magnet valve or a proportional pressure control magnet valve with a detector for detecting the position of a valve body of the valve.  
     CONSTITUTION: A calculated deviation signal 7 is added to a control signal 8 which is to be transmitted from a speed signal setter 5 to a proportional flow control magnet valve 3, thereby forming a modifying signal 9. A signal converter 10 converts the modifying signal 9 into a level of a valve body position signal, that is, the modifying signal 9 is converted into a conversion signal 11 by the signal converter 10. A comparator arithmetic circuit 12 compares a detection signal from a valve body position detector 4 of the proportional flow control magnet valve 3 with the conversion signal 11 to calculate a deviation between the two. The calculated deviation signal 13 is added to the conversion signal 11 to thus form a modifying signal 14 which is now converted by a further signal converter 15 into a signal level which is to be applied to a coil of the proportional flow control magnet valve 3. A finally necessitated feedback loop is the stage at which a deviation signal 7 is added to a control signal 8 to form a modifying signal.

Title: Reflection type liquid crystal display device and its production
Inventor: KURIHARA SUNAO
IPC: G02F1/1335
Filed: 1995-03-15
Abstract: PURPOSE: To simplify the production process of a reflection type liquid crystal display device. CONSTITUTION: The liquid crystal display device 21 has a liquid crystal layer 24 between one substrate member 22 for a display screen where light enters or exits and the other substrate member 23 where light is reflected. On the surface of the substrate 23 facing a liquid crystal layer 24, plural pixel electrodes 35 having reflecting property are arranged in a matrix. A color filter 25 which is a transparent film is formed by repeating a process of forming a thin film and patterning on the pixel electrode 35 while controlling the film thickness. Or, a metal film may be anodically oxidized to form an oxide film. When light enters the one surface of the color filter 25, part of the light is reflected on the surface and the rest is transmitted through the filter 25, reflected on the pixel electrode 35, and emitted from the first surface.  This light and the light reflected on the surface produce thin film interference. Therefore, the intensity of light in a specified wavelength region is relatively increased and the pixel is displayed in a specified color.
