Title: Manufacture of titanium fan disk by high-temperature hydrostatic pressure compression diffusion joining
Inventor: BURAIAN RESURII BEN
IPC: B23K20/00
Filed: 1992-07-10
Abstract: PURPOSE: To make it possible to produce a large-sized fan disk by butting the smooth surfaces against each other perpendicularly to a central axis, removing air from between the surfaces and diffusion joining cylinders at the terminals to each other by high-temperature isostatic pressing. CONSTITUTION: The cylinders 10 have peripheral flanges 16 at one end. The terminal surfaces 18 of the flanges 16 exist on the same plane as the terminal surfaces 14 of the cylinders 10 and both surfaces 14 and 18 are smoothly finished. Rings 2 made of titanium are inserted into grooves 20 of the flanges 16 and the two cylinders 10 are arranged to be abutted against each other, by which an annular chamber 26 is formed. The inner joint lines 30 in the bores 12 of the cylinders 10 are sealed by welding. The annular chamber 26 is evacuated by evacuation in the vacuum chamber and the peripheral joint lines 28 of the flanges 16 are welded. The rings 24 made of titanium prevent the hazardous metallurgical defect at the time of welding. The cylinders 10 are put out into the atmosphere and are diffusion joined by a high- temperature equilibrium pressure technique.  Since the annular chamber 26 is in a perfectly vacuum state and, therefore, the cylinders 10 are completely joined to each other and the large-sized fan disk may be produced.

IPC: H04N19/46
Filed: 1999-07-22
Abstract: PROBLEM TO BE SOLVED: To provide a frame synchronizing detecting circuit where a memory capacity to store coincidence/dissidence information of a synchronizing pattern is decreased and a low access speed to a memory is attained. SOLUTION: The frame synchronizing detecting circuit 10 consists of a serial parallel conversion section 1 that converts serial data into parallel data, a register 2, a pattern detection section 3, a frame detecting processing section 4 and an information storage section 5. Thus, only presence of coincidence of a synchronizing pattern in a retrieved block and position information of coincidence detection are stored without storing coincidence/dissidence information of all bits for each frame.

Title: Rolling mechanism of blind
Inventor: TAKEBAYASHI NAOKI
IPC: E06B9/322
Filed: 1999-07-22
Abstract: PROBLEM TO BE SOLVED: To reduce the number of part items and the number of work processes by forming a nipping part narrower than a width of a shaft in a part of a groove part. SOLUTION: A groove part 14a in which a shaft 12 is fitted is formed over the whole length in the axial direction on a peripheral face of a drum 14. A nipping part 14b which is narrower than a width of the shaft 12 and nips the shaft 12 strongly and a weak nipping part 14f having weaker nipping force onto the shaft than the nipping part 14b are formed in a part of the groove part 14a. First, the weak nipping part 14f of the drum 14 is gently pushed into the shaft 12. Since the weak nipping part 14f nips the shaft 12 with comparatively weak force, a mounting position of the drum 14 can be minutely adjusted. Next, the nipping part 14b is pressed into the shaft 12 with strong force and the nipping part 14b is elastically deformed and fitted in the shaft 12.  Since travel of the shaft 12 in the axial direction and peripheral direction is restrained after fitting, a caulked part and a shaft retainer which are provided separately become unnecessary.

Abstract: PROBLEM TO BE SOLVED: To obtain a receptacle type module which evades the accumulation of foreign matter and dust, suppresses variation in optical characteristics, and secures high reproducibility and reliability by forming a groove in a sleeve internal wall, which holds the ferrule part of an optical connector, in the ferrule insertion direction. SOLUTION: A receptacle 1 consists of a sleeve 3 which aligns the ferrule 9 of the optical connector with an optical axis 2, a screw part 4 which fixes the housing of the optical connector, and a flange part 5 which fixes the receptacle 1 to an external device in one structure. In the internal wall of the sleeve 3, the groove parallel to the insertion direction of the ferrule 9 is formed and extended up to the end part where the internal wall of the sleeve 3 abuts against an optical reference surface 7, wherein a 2nd groove 8 which communicates with the groove 6 is formed. Therefore, foreign matter and dust which flaws the internal surface of the sleeve 3 and the end surface and flank of the ferrule 9 can be moved temporarily to the groove 6 and further pushed out of the ferrule 9 with air pressure applied at the time of the insertion of the optical connector.

Title: Device and method for recording and reproducing image
Inventor: HARADA HISASHI
IPC: G09G5/397
Filed: 1994-08-31
Abstract: PURPOSE: To reduce an image filing size at the time of preservation and to accelerate display processing speed by selectively or simultaneously displaying a compressed image and a resized image preserved in the image recording device. CONSTITUTION: The image recording device expands inputted compressed image data A0 according to an expanding system corresponding to its compressing system while using an expanding part 1. Then, the processed image is displayed on a display part 6 and after it is confirmed by a confirming part 7 whether preserving that image or not, the image data are preserved by a preserving part 8. Besides, when displaying only one compressed image recorded by the image recording device, the image reproducing device retrieves the desired compressed image data A0 while using a retrieving part 10, afterwards, expands those image data corresponding to its compressing system while using an expanding part 11 and displays them on a display part 16.  Thus, the compressed image compressing a source image and the resized image resizing the source image are preserved by the image recording device, and the preserved compressed image and resized image are selectively or simultaneously displayed by the image reproducing device.

Title: Circuit breaker
Inventor: KIKUCHI RYUJI
IPC: H01H73/38
Filed: 1998-07-23
Abstract: PROBLEM TO BE SOLVED: To realize stable tripping without enlarging the external dimensions. SOLUTION: An inclined plane 34b backing away from a locking part 36 of a latch 35 is provided to a part to be locked 34 of a catch 32. Under normal conditions, a locking plane 34a of the catch 32 is locked on the locking part 36 of the latch 35. When a trip device is tripped to release locking of a lever 38 onto the latch 35, the latch 35 begins to rotate in the direction of an arrow B4, at the same time the catch 32 begins to rotate in the direction of an arrow B5. As the latch 35 rotates, the inclined plane 34a of the catch 32 contacts the locking part 36 on the way, then the working direction of the force F acting on the latch 35 at a locking point P is changed, which increases the distance a from the center of rotation of the latch 35 to the line of action of the force F, to increase torque in the direction tripping the latch 35.

Title: Crystal growth method for compound semiconductor
Inventor: OTSUKA NOBUYUKI
IPC: H01L21/205
Filed: 1991-08-20
Abstract: PURPOSE:To grow an upper layer compound semiconductor crystal of high quality when different type compound semiconductors are grown at the same temperature and to form an abrupt hetero boundary by simultaneously supplying carrier gas and gas having heavier specific weight than that of the carrier gas when a material of an element for constituting a compound semiconductor crystal is supplied. CONSTITUTION:When an InAs crystal is grown on a substrate 3, (CH3)3In and AsH3 are used as materials. The (CH3)3In and AsH3 are switched by a valve (b), alternately supplied to a reaction tube 1, and grown. H2 is used as the carrier gas, and Ar is simultaneously supplied at the time of supplying the (CH3)3In. Thus, since a surface temperature of the substrate 3 can be effectively lowered, the (CH3)3In can be supplied to the surface of the substrate in an undecomposed state as it is, and the methyl indium reaching the substrate 3 is eliminated as it is or rapidly decomposed to become In so as to contribute to the growth. Accordingly, an InAs atomic layer epitaxial growth can be conducted at 400 deg.C or higher.
