Filed: 1994-09-29
Abstract: PURPOSE: To provide a manufacturing method of a surface conduction-type electron emission element as an electron beam source with which the size of an image forming apparatus can be made wide and images with high quality can be provided. CONSTITUTION: Regarding a manufacturing method of a surface conduction-type electron emission element in which an electron emission part 2 is formed in a conductive thin film 3 bridging element electrodes 4, 5 on a substrate 1; the element electrodes 4, 5 are so formed on the substrate 1 as to make the height of the step part of each element electrode be different. After that the manufacturing process involves a process wherein an organometal solution containing component elements for the conductive thin film 3 is sprayed to the substrate 1 through the nozzle while potential being kept different between the substrate 1 and a nozzle. Consequently, even in the case the distance L between element electrodes is so made wide as to match with the level of an exposure technique for a large surface area, electron emission elements with high reproducibility of the shape and the position of the electron emission part and uniform electron emitting properties can be manufactured.

Filed: 1989-10-04
Abstract: PURPOSE:To prevent the occurrence of void even if a third person is asked to take a photograph by inhibiting a photographing lens from being driven to an infinite position regardless of range-finding information when a void preventing switch is turned on. CONSTITUTION:A photographing lens driving system is provided with a mu-control 4, a control IC 10, first and second switches 6 and 7 which are turned on by the first and second strokes of a shutter button, a switch 8 for preventing void, etc. When the switch for preventing void 8 is turned on, the mu-control 4 charges a strobe circuit 20 and stores information that the switch 8 is turned on. When the shutter button is released in this condition; that is, a SW2 switch 7 is worked, actual lens driving is limited to a finite distance even if the range- finding information indicates the infinite distance. Therefore, void is effectively prevented even if a third person is asked to take a photograph.

Title: Rare-earth iron resin-bonded magnet
Inventor: SAKURAI MITSURU
IPC: H01F1/08
Filed: 1987-10-16
Abstract: PURPOSE:To obtain an excellent corrosion-preventive effect with a thin coating by a method wherein the material, formed by adding the fine powder of non- magnetic metal or a metal oxide of 10mum or less in grain diameter to the magnetic powder consisting of the fundamental composition of R(rare-earth metal)-Fe-B, is used as raw material. CONSTITUTION:The material formed by adding 5-50wt.% or non-magnetic metal or a metal oxide of 10mum or smaller in grain diameter is added to the magnetic powder having the fundamental composition consisting of rare-earth metal (R), iron (Fe) and boron (B), is used as raw material. When the R-Fe-B magnetic powder prepared by a quench thin strip method is used as the raw material for a resin-bonded magnet, the irreducible minimum of grain diameter of the powder is to be 30mum. As a result, recesses and projections of 15-20mum are formed on the surface of the magnet, but the surface roughness can be improved by adding the fine powder of 10mum in grain diameter, with which the recesses on the magnetic surface are filled up. As a result, the roughness of the magnet surface can be improved, and the corrosion-preventive layer coated on the surface can be made thin.

Filed: 1988-10-17
Abstract: PURPOSE: To decrease the amount of a required pressure medium to decrease in input energy into a pressure source by forming a closable pressure medium connection between a booster chamber and a resetting chamber, and connecting the resetting chamber with a reserver through the closable pressure medium connection. CONSTITUTION: To release the pressure of a master cylinder, a valve 26 provided at a pressure medium connection between a booster chamber 8 and a resetting chamber 9, and a valve 28 provided at a pressure medium 27 between a resetting chamber 9 and a reserver chamber 29 are switched respectively. As a result, the pressures of the two chambers 8, 9 are increased, so that the pressure acting on a booster piston 3 is released. The additional force of the master cylinder acting on a tappet energizes the booster piston 3 and is returned to its braking release position, so that the pressure medium proceeds to the resetting chamber 9. The pressure medium needs to be supplied by a pressure source. It is thus possible to decrease the necessary amount of pressure medium, thereby reducing input energy into a pressure source.
