Title: Automatic paper feeding apparatus
Inventor: YONEKURA SEIJI
IPC: B65H1/24
Filed: 1984-12-07
Abstract: PURPOSE:To permit the small-sized constitution and stable extraction of paper by using an extraction roller in common with a separating roller and preventing the taking-out of the paper in the next order. CONSTITUTION:A sheet 52 of paper is extracted by the transfer force of a roller 7 which overwhelms the suppressing force of a belt 18, and guide into the gap between guide plates 64a and 64b. When the top edge of the sheet 52 of paper in extraction is transported by transportation rollers 65a and 65b, a shaft 31 is revolved in the direction shown in the figure by a rotary solenoid 36. At the same time, the revolution of the extracting roller 7 is brought into stop. Therefore, the group of the sheet 52 of paper in the next order is suppressed by a roller 34 through the sheet 52 of paper in extraction, and taking-out is prevented. Therefore, constitution is made small-sized, and the formation of curl on paper is prevented by preventing the taking-out of paper in the next order, and the stable extraction of paper is permitted.

Abstract: PURPOSE:To prevent the occurrence of uneven packing to eliminate warping, deformation, etc., occurring at the time of degreasing and sintering by providing at least a pair of gates facing each other. CONSTITUTION:Ceramic powder 32 injected into a sprue 7a successively goes through neutralizing runners 29, 29, main runners 28, 28 and a branch runner 27 and thereafter is packed, as shown by the arrow L1,..., into a cavity 22 from a plurality of gates 25 facing each other pair by pair. The powder 32 is packed bidirectionally from the gates 25... facing each other. Thus, the gates 25... for injecting the ceramic powder 32 into the cavity 22 are provided so as to face each other pair by pair. As compared with the case of a one-way gate, accordingly, uneven packing of the ceramic powder 32 decreases so that the occurrence of warping and deformation caused by such uneven packing at the time of degreasing and sintering can be prevented consequently.

Title: Toner for liquid development
Inventor: NAKAMURA HIROTO
IPC: G03G13/10
Filed: 1989-10-03
Abstract: PURPOSE:To improve the adhesive strength of the toner on a medium to be transferred by adding a UV curing resin into a developing soln. and irradiating the soln. with UV rays. CONSTITUTION:The photoconductive toner 11 is dispersed into an insulating solvent contg. a polymerizable monomer contg. >=1 vinyl groups, etc., or a resin (UV curing resin) 12 which is crosslinked by UV rays and a polymn. initiator and after the toner is transferred onto the medium to be transferred, the toner is irradiated with UV rays. A small amt. of the insulating solvent remains on the medium to be transferred upon completion of the transfer. The curing reaction of the toner starts when the toner is irradiated with the UV rays. The curing reaction of the toner 11 progresses by including the UV curing resin 12 penetrated in the medium to be transferred and, therefore, the toner 11 and the medium to be transferred cause a reaction as if crosslinked. The adhesiveness of the photoconductive toner 11 to the medium to be transferred is increased in this way.

Filed: 1988-10-15
Abstract: PURPOSE:To ensure disconnection between a capacitor element and a cathode terminal in the case of failure by providing a low-melting polymeric material arranged on the side toward which a shape memory alloy is deformed. CONSTITUTION:A capacitor element 11 is connected with a cathode terminal 17 through a shape memory alloy 15. One end 15a of the shape memory alloy 15 is connected to the cathode terminal 17 while the other end 15b is connected to the surface of the capacitor element by means of a low-melting conductive bonding material 16. When a temperature is raised, the low-melting conductive bonding material 16 connecting the capacitor element 11 with the shape memory alloy 15 is molten and the shape memory alloy 15 is deformed. Thereby, the other end 15b of the shape memory alloy is disconnected from the surface of the capacitor element. Accordingly, circuit components around the capacitor can be prevented effectively from being burnt or damaged and thus the safety can be improved.

Abstract: PURPOSE:To prevent the abnormal rising of a temperature in a fixing roller by respectively arranging contact type protective devices such as a thermostat, etc., on both end sides of the fixing roller. CONSTITUTION:A thermistor 33 for detecting the temperature of the surface of the roller 29 is installed on the central position of the surface of the fixing roller 29. And also, a pair of thermostats 34 are arranged on both end sides of the fixing roller 29 so that each of them may be respectively brought into contact with the surface of the fixing roller 29. When a power supply switch 37 is turned on, light is emitted in the heater 28 so as to heat the fixing roller 29 from the inside. In the case that the surface temperature of the fixing roller 29 is not detected by the thermistor 33, and also the control is not effectively performed by a triode AC switch 35 even after the temperature is detected by the thermistor 33, the surface temperature of the fixing roller 29 is kept on rising. In the case that the temperature rises >= a specified degree, either of the pair of thermostats 34 on both end sides of the fixing roller 29 is actuated, and the heater 28 is broken from the power supply 37.

IPC: G01S7/523
Filed: 1987-10-15
Abstract: PURPOSE:To decrease grating lobes by arraying ultrasonic wave vibrators which have openings at prescribed intervals at prescribed intervals and arranging a mask which has opening corresponding to the respective vibrators on them. CONSTITUTION:The mask 2 which has the openings 3 formed at positions corresponding to the respective ultrasonic-wave vibrators 1 is arranged. Then the openings of the respective ultrasonic wave vibrators 1 are formed asymmetrically about the center of the centers of the ultrasonic-wave vibrators. The gaps d1 of the openings of the ultrasonic-wave vibrators 1 are equalized to the gaps d2 of adjacent ultrasonic-wave vibrators. Consequently, even when the shapes of the ultrasonic-wave vibrators are large, the ultrasonic-wave vibrators having the array pitch reduced equivalently by the respective openings 3 of the mask 2 are arrayed, so directivity having no grating lobe is obtained.

Abstract: PURPOSE:To make precision control of the composition and suppress the costs by separately sintering a molding of electrode material and a specifically which dense film made of lanthanum chromate formed through doping of alkali earth metal, and adhering them with a humidity exceeding a certain level. CONSTITUTION:The green body of a thin film is made of doped lanthanum chromate with alkali metal by means of the tape casting method so that the film thickness lies between 5-200mum, and this is subjected to sintering to produce a dense thin film. As the alkali metal, Sr or Ca is used from the viewpoint of electroconductivity, and the ratio of the A site to B site shall favorably be 0.95-1 in order to have chemical stability. The sintering shall preferably take place at 1400-1600 deg.C in an atmosphere with the CrO3 vapor pressure put under control, which however is equipped with a waviness, and therefore, this must be flattened by applying a weight consisting of a flat plate. The resultant is pressed to a sintering of electrode material and adhered by heating at 1000 deg.C or more. Because of flexibility of the thin film, it is also possible to make adhesion with the peripheral surface of a cylindrical work for electrode.
