Title: Image forming device
Inventor: KIMURA HITOSHI
IPC: G03G21/00
Filed: 1988-04-18
Abstract: PURPOSE:To prevent a failure in forming an image by making a removal member brought into contact with an image carrier means so that residual developer and refuse of paper, etc., on the image carrier is removed while the image carrier means moves and moving the removal member which is still in contact with the image carrier means in an opposite direction so that the refuse of paper sticking to the removal member is scraped at the time of turning on a power source or at the time of completing a prescribed processing. CONSTITUTION:While the image carrier means 11 is moved in a prescribed direction by a moving means under the control of a control means 32, the removal member 41 provided in a cleaning means 30 is brought into contact with the image carrier means 11 so as to remove the developer and the refuse of paper, etc., remaining on the image carrier means 11. At the time of turning on the power source or at the time of completing the prescribed processing, the removal member 41 which is still in contact with the image carrier means 11 is moved in the direction opposite to the prescribed direction, thereby scraping the refuse of paper sticking to the removal member 41 with a frictional force caused by the above-mentioned contact. Thus, the fault of cleaning does not occur even if the refuse of paper is caused and the failure in forming the image can be prevented.

IPC: H01R13/42
Filed: 1994-04-08
Abstract: PURPOSE:To prevent a terminal metal from being fitted to a fixed body in the half-inserted state. CONSTITUTION:A retainer 20 is movably assembled into a connector housing 11, the retainer 20 is moved to the hook position and hooked on a terminal metal 16 only when the terminal metal 16 is normally inserted into a terminal storage chamber 13 formed in the housing 11, and the retainer 20 is kept at the floated state from the surface of the housing 11 when the terminal metal 16 is half-inserted.

Inventor: OCHI HIDEKI
IPC: H01J23/40
Filed: 1990-04-11
Abstract: PURPOSE:To omit pressing process of an exhaust pipe, and to cut the number of processes thereby by forming the exhaust pipe into a pipe of the same diameter from one end through the other, and by forming the diameter of the opening side of an antenna cap that covers the exhaust pipe smaller than that of the part that covers the sealing part of the exhaust pipe. CONSTITUTION:An antenna cap 25 is formed out of shape memory alloy such as an Ni-Ti alloy or Cu-Al-Zn alloy, and the shape is stored in such a way that the shape memory temperature is set slightly higher than the room temperature, and the diametrical size of a tongue piece 26 is thereby contracted and thus densely connected to the outer periphery of an exhaust pipe 24. A vacuum tube is heated and the air therein is exhausted through the exhaust pipe 24, which is seal-cut along with an antenna conductor 4. In this structure, pressing process of the exhaust pipe 24 is unnecessary, and the number of processes is thus reduced.

Abstract: PURPOSE:To provide a ferroelectric element composed of a substrate and a ferroelectric thin film, wherein the substrate has a specific average thermal expansion coefficient between room temperature and the film-forming temperature of the ferroelectric thin film and the ferroelectric thin film is strongly orientated in a prescribed direction. CONSTITUTION:A plasma is generated between a pair of parallelly arranged electrodes by high-frequency power in a vacuum chamber in the presence of a reactive gas such as oxygen.

Filed: 1989-04-18
Abstract: PURPOSE:To form a dense thermally-sprayed film having a smooth surface by melting the thermally-sprayed film by using laser light or converged light and solidifying the film again. CONSTITUTION:A powdery thermal-spraying material consisting of metals, ceramics, cement, etc., is put into a molten or nearly molten state by using a heat source, such as plasma, and is blown onto a base material such as steel plate, concrete or wood, etc., to form a thermally-sprayed film. The thermally- sprayed film obtd. in such a manner is melted by using a laser light or converged light and the thermally-sprayed film alone is localizingly heated and melted by changing the intensity, time, irradiation direction, and moving speed of the irradiation light or the combination thereof. The thermally-sprayed film alone is melted and is solidified again regardless of the kinds of the base material by this method and, therefore, the dense thermally-sprayed film having a smooth surface is formed. The waterproofness of the thermally-sprayed film is, therefore, improved, and the deterioration, failure or corrosion of the base material is prevented.

IPC: G01N27/12
Filed: 1978-08-08
Abstract: PURPOSE: To make accurate periodical water measurement possible by measuring the volume of water by crushing grains between a fixed electrode and movable electrode and then by closely measuring the volume of water again after washing off crushed grains sticking to each electrode surface by a flow of grains dropping.  
     CONSTITUTION: Inside of humidity regulation tank 1, vertical shunting cylinder 4 of a small diameter is fitted. The periodical rotation of motor 10 advances slider 7 and grains dropping through shunting cylinder 4 are pushed against fixed electrode 9 by vertical moving electrode 8 to crush grains, thereby measuring water accurately. After measurement, motor 10 reverses to move electrode 8 backward, and consequently grains dropping through shunting cylinder 4 washes off crushed grains sticking to vertical electrodes 8 and 9, so that next measurement can be started after fixed time. Therefore, when the percentage of water reaches a desired value, the unit can automatically be stopped by knowing it accurately.

Abstract: PROBLEM TO BE SOLVED: To enable receiving data without a parity error when the parity error occurs at one side continuously or at random by using a clock whose cycle is half an input latch clock in a parity check latch and mutually and repeatedly receiving another highway data at the time of parity error occurrence. SOLUTION: The first and second latches 10 and 13 respectively permit first and second highway data to be synchronized with the input latch clock (CP3RA) so as to latch them and output them in accordance with the output control signal of a selecting part 18. A parity check latch 16 receives the check result of a parity check part 15, permits it to be synchronized with a reference clock (CP 2D/A) whose cycle is half the input latch clock (CP3RA) and outputs it to a control part 17. The control part 17 receives the outputs of the VALID latches 11 and 12 and the parity check latch 16 by respective input ends. When the outputs of the latches 11 and 12 are normal but the output of the parity check latch 16 is the error, the both outputs of the control part 17 are controlled to be provided to the selecting part 18 in a toggle state.

Title: Firing method of ceramic and production of ceramic multilayer circuit board
Inventor: NISHIMURA SHIN
IPC: C04B35/638
Filed: 1994-05-11
Abstract: PURPOSE:To completely remove a binder at a low temp. by adding a binder resin to a ceramic powder material to produce a green sheet, keeping the green sheet for specified time at a specified temp. in a nonoxidizing atmosphere, and then sintering the sheet. CONSTITUTION:A binder resin (e.g. a soln. obtd. by dissolving ethyl methacrylate polymer in methyl ethyl ketone) is added to a ceramic powder material to produce a green sheet. Then the green sheet is maintained for specified time in a nonoxidizing atmosphere at <=600 deg.C which is the depolymn. temp. of the binder to decompose the binder into monomers by depolymn. reaction so that the binder is removed by scattering the monomers. Then the temp. is raised to the firing temp. of the ceramic to sinter the sheet. By this method, the binder can be completely removed at a rather low temp. in the removing process of the binder. Therefore, low temp. firing can be done which enables use of a low resistance metal having the low melting point. Thus, a ceramic multilayer circuit board having the low dielectric const. is produced.
