Title: Pilot-operating electromagnetic pressure control valve
IPC: F15B13/043
Filed: 1992-03-25
Abstract: PURPOSE:To speed up responsiveness and control high-pressure main circuit fluid by returning the nozzle back pressure of a nozzle-flapper mechanism to a plunger to allow the plunger to follow a flapper, thereby opening and closing a main valve through a pilot valve to control the main circuit fluid. CONSTITUTION:A nozzle 55 is integrally made with a plunger 54 to slide in a sliding hole 51, and a pilot valve VP is composed of a seat 56, a poppet 58, and a spring 59. A flapper 61 is fixed to the tip of a rod 66, and the flapper 61 is positioned opposite to the nozzle 55 to form a nozzle-flapper mechanism N. The flapper 61 rests at a fixed position by a thrust which corresponds to an input current of a proportional solenoid 64 to keep a nozzle clearance G of the nozzle-flapper mechanism N. When the pressure of a main circuit fluid Lm is increased, the pressure of a pilot fluid Lp in a pilot passage p8 is increased to push up the poppet 58. Simultaneously the nozzle 55 is pushed up integrally with the plunger 54 to narrow the nozzle clearance G, and thus the nozzle back pressure is increased.

Title: Image observation device
Inventor: ITO KAZUYA
IPC: G02F1/1335
Filed: 1993-03-25
Abstract: PURPOSE:To reduce the reflection of external light, entering the image observation device having at least one optical system between a liquid crystal display device, etc., and the eye of an observer, and make an image easy to see by arranging a polarizing element between the optical system and eye. CONSTITUTION:In the image observation device like an electronic finder which enables an image formed by the liquid crystal display device LCD, etc., to be observed through a lens 5 as the optical system, a polarizing filter 6 which has the axis of polarization set to the same direction with the eye-side polarizing plate 4 of a liquid crystal panel 3 constituting the LCD is arranged between the lens 5 and eye. The external light is transmitted through the polarizing filter 6 twice when made incident on the electronic finder from the eye side and exiting to the outside after being reflected inside. The light emitted from the LCD, on the other hand, is already polarized, so the intensity after the light is transmitted through the polarizing filter 6 is affected only by the parallel transmissivity. The ratio of the external light of the LCD made incident on the eye to the reflected light of the external light can be improved by as much as the reflected light of the external light is reduced.

Abstract: PURPOSE:To eliminate the disturbance of a toner image due to a removed carrier, by arranging a magnetic attracting means between a developing part and a transfer part to remove the magnetic carrier which is stuck together with the toner to the surface of the latent image of a photoreceptor and transferring the toner well in the transfer process. CONSTITUTION:A magnetic attracting means 10 is arranged between a developing device 4 and a corona discharger 5 for transfer so as to face a photoreceptor 1. By providing the magnetic attracting means 10 in this manner, a carrier 18 is attracted to the magnetic attracting means 10 together with the toner and is removed from a toner image part stuck to the latent image on the photoreceptor 1 when this toner image part faces the magnet 10. That is, though the toner as well as the carrier may be stuck to the electrostatic latent image part simultaneously in the developing part, the stuck carrier 18 receives the magnetic attraction and is attracted to the magnetic attracting means 10 when it faces the magnetic attracting means 10. At this time, the toner does not receive the action of the magnetic attraction and is not attracted to the magnetic attracting means 10 because it is not a magnetic material. Thus, the image is transferred well without omission of image.
