Title: Scroll compressor
Inventor: ABE NOBUO
IPC: F04C23/00
Filed: 1998-10-15
Abstract: PROBLEM TO BE SOLVED: To improve abrasion resistance property by forming a sliding surface of an Oldham's ring of a self-rotation preventing mechanism as a dissimilar surface, carrying out precision work after steam process is carried out on an iron sintered alloy made Oldham's ring for improving abrasion resistance property, and mixing a base with a steam layer (a oxide film) having high hardness. SOLUTION: In a compressor in which a scroll type compression mechanism 5 in an enclosed container is driven by an electric motor, a turning scroll is turned through an Oldham's ring 6. Protrusions 17 are formed on two positions on a rectilinear diameter of a surface opposed to the turning scroll, and protrusions 18 are formed on two positions on a rectilinear diameter of a surface opposed to a frame, and they are faced to each other in perpendicular direction. In this case, steam process is carried out on the Oldham's ring 6 made of iron sintered alloy, and precision work is carried out on its surface. A base is mixed with a steam layer (an oxide film) 22 having high hardness and which is generated in a special hollow hole in the sintered alloy, and it is suppressed to agglutinate with counterpart cast iron surface so as to improve abrasion resistance property.

Title: Artificial sunlight irradiating device
Inventor: KUSUHARA MASAKI
IPC: G01J1/08
Filed: 1989-11-10
Abstract: PURPOSE:To facilitate the installation and to reduce electromagnetic noises by accumulating all charges for generating a pulse current exceeding a rated current when irradiation is not performed, superposing the pulse current upon a extremely small current when the irradiation is performed, and generating a discharging pulse current. CONSTITUTION:Even when a discharge lamp 2 is discharged and stopped from being energized by a lamp driving circuit 19, the extremely small current I1 flows to the lamp 2 since a switch 12 is ON; and a secondary battery 4 is discharged with the output current of a stationary photocurrent control circuit 18 to accumulate charges required to discharge the pulse current which is about four times as large as the rated current of the lamp 2 for a necessary time. Then when a crest value control circuit 10 is energized, the circuit 10 stabilizes the crest value of the pulse current I2 based upon the charges accumulated in the secondary battery 4 to a specific value and then outputs the pulse current I2 to the circuit 19. Thus, the pulse current I2 required for the irradiation can be generated in the device, so there is no restriction as to the installation and the path of the current becomes short, so the intensity of electromagnetic noises is reducible.

Title: Disturbance wave reducing device
Inventor: ANDOU ATSUHISA
IPC: H03D1/22
Filed: 1998-10-15
Abstract: PROBLEM TO BE SOLVED: To reduce the degradation of communication characteristics due to disturbance wave caused by the frequency deviation of a local oscillation signal of an other radio equipment. SOLUTION: A reception signal received by an antenna 10 is supplied via a filter 11 to a mixer 12. The mixer 12 mixes the reception signal passing via the filter 11 and a local oscillation signal Lo outputted from a local oscillator 13, generates a base band signal and supplies it to a demodulator 15. When the communication is not performed, a frequency control circuit 16 discriminates frequency to minimize the level of the base band signal by successively changing a frequency fo of the local oscillation signal Lo within a prescribed range and controls the frequency fo of the local oscillate signal Lo into a discriminated frequency.  Thus, even if the frequency of radiated signal radiated from the local oscillator of the other radio equipment deviates from the frequency of local oscillation signal of present radio equipment by a solid dispersion or the like, degradation of communication characteristics due to the interference wave caused by the deviation of local oscillation signals can be reduced to a minimum.

IPC: H01S5/042
Filed: 1994-11-29
Abstract: PURPOSE: To reduce resistivity of a P-type upper clad layer, by constituting the upper clad layer of a first subclad layer of a second conductivity type, a second subclad layer of a first conductivity type, and a third subclad layer of a second conductivity type which are formed in order from the active layer side. CONSTITUTION: An upper clad layer is a multilayered clad layer 29 wherein a first subclad layer 24 of a second conductivity type, a second subclad layer 26 of a first conductivity type, and a third subclad layer 28 of a second conductivity type are constituted in order from the side of an active layer 14a. When the first conductivity type is the N-type, and the second conductivity type is the P-type, the multilayered clad layer 29 forms PNP structure. When the multilayered clad layer 29 is sandwiched between electrodes 32 and 34, a forward bias voltage is applied, and a laser light is oscillated from the active layer 14a, the resistance of the multilayered clad layer 29 of PNP structure is small, because the carrier mobility of the second subclad layer 26 is large as compared with that of the first and the third subclad layers 24 and 28.

Title: Electrostatic latent image developing device
Inventor: ARAGAKI KOICHI
IPC: G03G15/09
Filed: 1985-12-27
Abstract: PURPOSE:To obtain a clear image by rotary-driving a developing sleeve and a toner supplying roller even if a developing device is in a time zone which does not contribute to a developing. CONSTITUTION:Even if a developing device 2 is in a time zone which does not contribute to a developing, a toner is supplied from a toner supplying roller 9 to a developing sleeve 4. On the other hand, since the quantity of the toner which is recovered by the toner supplying roller 9 is decreased, a toner is fully maintained on the circumferential surface of the developing sleeve 4 substantially for the next-time developing action. Moreover, the toner maintained on the circumferential surface of the developing sleeve is mixed with a carrier and agitated during such a time, thereby increasing the electrostatic charge quantity. Thus, even if an image which has much toner consumption, like a solid black image, etc., is copied continuously, a clear image can be obtained without the deterioration of an image density.

Abstract: PROBLEM TO BE SOLVED: To automatically divide paper into reams with every fixed number of sheets without relying on manual work, and transfer them to the next process by supplying two-ply marker tapes to paper to be stacked from a tape inserter, and inserting a partition plate into a position of the marker tapes. SOLUTION: Two marker tapes 7 of the uppermost part of a paper receiving stand on which paper is already stacked are opened by a sucker 8. A partition plate 9 is inserted between its two marker tapes 7, and when it is pushed up by a raising cylinder 10, an end part of paper 11 equivalent to a single ream of the uppermost part is raised, and a slight clearance is generated between lower residual paper. Next, a pressing-down plate 12 is inserted between paper equivalent to a single ream of the uppermost part and the lower residual paper, and the lower residual paper is pressed down, and is fixed. During this time, since an end part of paper equivalent to a single ream of the uppemost part is supported with a stopper 13, there is no possibility of causing positional dislocation.
