Title: Photorefractive crystal
Inventor: MATSUMOTO TAKAHIRO
IPC: G02F1/35
Filed: 1993-09-29
Abstract: PURPOSE:To provide a photorefractive crystal which has stable quality and can be easily integrated. CONSTITUTION:This photorefractive crystal is produced by adding a donor (Cr) and an acceptor (Zn) to a porous silicon film. The porous silicon film can be formed by using e.g. the anodizing method. In the photorefractive crystal thus produced, at the time of irradiating a part of the surface of the porous silicon film with light, the electrons at the donor level in the irradiated part are excited to diffuse into the porous silicon film and in the non-irradiated part, the electrons fall down to the acceptor level. Thus ununiformity of the spatial charge distribution is generated to form a electric field within the porous silicon film. Since the porous silicon has the secondary electro-optic effect, a change in its refractive index is effected by this electric field.

Filed: 1994-11-01
Abstract: PURPOSE: To shorten the first printing time without making a process speed fast by setting the carrying speed of a carrying member carrying a recording material ejected from a fixing means at a specific speed. CONSTITUTION: A transfer material P ejected from a fixing device 6 is held/ carried to paper ejecting rollers 10 and 11, to be ejected outside a machine. The ejecting roller 10 is driven to rotate at a speed 120-200% higher than the process speed for forming an unfixed image on a photoreceptor drum 1 and the transfer material P or a fixed image on the material P (for instance, the carrying speed of the fixing device 6 carrying the material P). While the material P is simultaneously carried by a fixing roller and the ejecting roller 10, it slips against the material P, so that it is carried at the carrying speed of the fixing device 6. While the material P is carried only by the ejecting roller 10, after the material P passes through a fixing nip part, the material P is carried at the speed of the ejecting roller 10.

Title: Valve-opening mechanism of fire hydrant apparatus
Inventor: KANAI TAKUMI
IPC: A62C35/68
Filed: 1989-10-18
Abstract: PURPOSE:To enable opening a discharge valve simultaneously with taking out a fire hose nozzle by constituting an apparatus in such manner that, when the fire hose nozzle is taken out from a nozzle holder, the detent part of the nozzle biases a latch to move a moving table and a transmission means connected with the table is drawn. CONSTITUTION:When the handle 8 of a fire hose nozzle is drawn, a projection 6 is being guided by long grooves 5, 22 while moving. In this case, the projection 6 in contact with the rear end 5b of the long groove 5 biases a latch 12, of which rotation is regulated by a pin 17, in the same direction. When the projection 6 moves further in the same direction, the projection 6 enters a run-off 7, is released from the engagement with the latch 12 to deviate from the long groove 5, and the fire hose nozzle 1 is removed from a nozzle holder 2. When a biasing force is applied to the latch 12, a moving table 11 moves in the same direction as the latch 12 against the elasticity of a coil spring 10. Thus, a wire 18 connected with the table 11 also moves in the same direction, the lever of a discharge valve rotates and the discharge valve is opened.
