Title: Metallized graphite brush
Inventor: KOBAYASHI TERUO
IPC: H02K13/00
Filed: 1987-06-01
Abstract: PURPOSE:To form an electrical brush having a suitable film-regulating action by laminating a layer composed of copper-covered graphite paricles and a layer composed of a mixture of copper powder and graphite powder alternately and by molding and baking the laminated product. CONSTITUTION:A crystalline graphite powder passing 80 meshes is coated with copper in such manner that the copper content in a copper-covered graphite powder obtained by an electroless deposition is 40% by weight. Said copper- covered graphite powder is filled into the metal mold of a mechanical press to be temporarily molded under the pressure of 1ton/cm<2>. Then, 50% by weight electrolytic copper powder, 47.5% by weight crystalline graphite powder, and 2.5% by weight phenolic resin powder are mixed with each other by a twin- cylinder mixer to form a molding powder, which is filled onto said temporarily molded product. Thus, main molding is conducted while a pigtail is embedded under the pressure of 4.5ton/cm<3>, to obtain a compact of electrical brush having a layer 9 composed of a mixture of copper powder and graphite powder on a layer 8 composed of copper-covered graphite powder.

Title: Overcurrent protection circuit
Inventor: TANIMURA YASUNARI
IPC: H03K19/003
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To provide an overcurrent protection circuit that does not malfunction owing to noise. SOLUTION: A circuit has a transistor Tr1 where the emitter is connected to a power supply voltage VS via a resistor R1 and the base is connected to a grounding potential via a resistor R2 for supplying current from the collector to a current supply target 10, and a transistor Tr2 where the emitter is connected to the power supply voltage VS and the collector and the base are connected to the base of the transistor Tr1 and the emitter, respectively. When the potential difference across the resistor R1 reaches a specific value or more, the resistor Tr2 is turned on and allows the transistor Tr1 to be turned off.  In this case, the emitter of the transistor Tr2 is connected to the power supply voltage VS via a resistor R4, and the furthermore a capacitor C1 is connected between the emitter and the ground potential, thus eliminating the phase difference and the potential difference between the emitter voltage VE2 and the base voltage VB2 of the transistor Tr2 and preventing the transistor Tr2 from malfunctioning when noise is generated in the power supply voltage VS.

Title: Paper conveyance control system for printing device
Inventor: IIDA KAZUHIKO
IPC: B65H7/06
Filed: 1994-06-21
Abstract: PURPOSE:To use a common video interface even when the usable stylized paper size varies according to the machine type by reporting the paper length corresponding to the instructed paper size to an engine from a controller, and allowing the engine to control the paper conveyance based on the paper length. CONSTITUTION:A controller 7 calculates the paper length from the instructed paper size and reports it to an engine 11, and the engine 11 considers that the actual paper of the reported paper length exists and implements paper conveyance. The engine 11 measures the actual length when the paper is conveyed and reports it to the controller 7, and the controller 7 judges the presence of the paper size error based on the actual paper length reported from the engine 11. Since the paper conveyance is controlled based on the paper length, the engine 11 is not required to consider the stylized paper size, thus a common video interface can be used even when the usable stylized paper size varies according to the machine type.

Title: Serial recorder
Inventor: HIRANO HIROFUMI
IPC: B41J19/20
Filed: 1988-06-06
Abstract: PURPOSE:To simplify a carrier driver and to easily cope with an expansion and contraction type recorder by providing means for applying a force for pressing and reciprocating a carriage at the end of the moving range of the carriage. CONSTITUTION:The supporting legs 20, 21 of a serial printer have different lengths to inclined the printer at theta with respect to a horizontal plane. When a print signal is fed from a computer, a plunger 1-L of a home position side first presses a carriage E-4 rightward, and ink is discharged to print synchronously with an encoder 3 while detecting the position of a print head E-1 by the encoder 3. When the carriage E-4 is moved to its right end, the carriage is smoothly stopped by a damper 2-R. If necessary, a right side plunger 1-R presses the carriage E-4 leftward to print. These operations are repeated to serially print reciprocatingly. When the print is finished, the drive of the plunger 1-L (1-R) is stopped, and the carrier E-4 is returned to its home position by its own weight.

Title: Primary radiator for parabolic antenna
Inventor: OUMARU KENJI
IPC: H01Q19/13
Filed: 1988-06-06
Abstract: PURPOSE:To improve the matching between a primary radiator and a parabolic reflector and to attain small size/light weight by using a microstrip antenna element as a radiation part and providing a horn. CONSTITUTION:A microstrip antenna element comprising a parasite element 44, a radiation element 46 and a ring conductor 50 is arranged at the bottom of a horn 42 and the microstrip antenna element is used as the radiation part. Since the microstrip antenna element acts like a circular-linear polarized wave conversion or the like, a dielectric substance having needed in a conventional radiator can be omitted. On the other hand, the matching between a primary radiator 36 and a reflector of the parabolic antenna is improved. Thus, small size/light weight is attained.

Abstract: PURPOSE:To obtain an electric-discharge lamp with a special orientation and brightness distribution which gives an increased illumination in a designated direction, by applying a solution consisting of a substance which contains a photosensitive substance and is hardened with light, and a  solvent to a film made of a light-reflecting substance, which is selectively provided on the inner  wall of an electric-discharge tube. CONSTITUTION:A light-reflecting substance made of an aqueous titanium-oxide solution or the  like is applied to the inner wall of an electric-discharge tube and dried. The light-reflecting film  thus formed is coated with a solution which consists of a solvent and a substance which is hardened with light and contains either a diazo compound or a dichromic compound that are sensitive  to lights with a wave length of 200-450nm, or a cinnamic compound which is sensitive to lights  with a wavelength of 200-500nm, before the coating of the solution is dried. After that, light is  irradiated over the surface of the dried coating made of the resin which is hardened with light by  means of a high-pressure mercury lamp or the like, except for a part of the coating which is in a  direction from the center axis of the cylindrical electric-discharge tube and is opened in using the tube. Thus the hardening of the dried coating except for this part is selectively accelerated. Consequently, the illumination of the electric-discharge lamp in a designated direction can be enhanced.

Abstract: PURPOSE:To reduce the required amount of cooling water by a method wherein a temperature test is performed with water-side circuits of a plurality of water- cooled coolers for cooling a forced oil water-cooled transformer being connected serially, and the measured value is corrected to the normal condition where the water-side circuits are connected in parallel. CONSTITUTION:A temperature test is performed by supplying water to water- side circuits leading from a water supply pipe 7 to a discharge pipe 8 through an adjustment valve 5 with water-cooled coolers 1, 2, 3 being connected serially. Now, exchange heat value of the water-cooled coolers is expressed by the product of heat conductivity and heat conductive area of the water-side circuits on both inner and outer sides, and temperature difference between oil and water. It is thus possible to make conversion to the normal condition where the water- side circuits of the plurality of water-cooled coolers are connected serially, by correcting the measured value resulted from the test. By doing so, the required amount of cooling water can be reduced and the temporary piping operation can be simplified.
