Title: Method of coating super alloy product with heat-insulating film and heat-insulating film
Inventor: DEEBUITSUDO SUTAFUOODO RITSUKA
IPC: C23C28/00
Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To improve adhesion between a ceramic thermal barrier coating and a super alloy article.  
     SOLUTION: The ceramic thermal barrier coating 28 for a superalloy article 20 is caused to adhere to the superalloy article by applying platinum to the superalloy article 20 and heat-treating at a temp. of 1,100-1,200°C for 1 hr. This causes aluminum to diffuse from the superalloy article 20 into the platinum to form a platinum enriched outer layer 24, which generally includes a platinum enriched γ phase 36 and a platinum enriched γ' phase 38. An alumina layer 26 is formed between the outer layer 24 and a ceramic coating 28. The platinum enriched γ phase 36 and the platinum enriched γ' phase 38 in the outer layer 24 reduces the migration of transition metal elements to the ceramic coating to enable a very pure alumina layer 26 to be formed.

Title: Fuse for laser trimming of semiconductor integrated circuit device
IPC: H01L21/82
Filed: 1989-12-25
Abstract: PURPOSE:To effectively cut even in the case of the positional deviation of a laser by forming a fuse for a laser trimming of a semiconductor integrated circuit device in a slender and plural times reciprocating shape at a narrow pitch. CONSTITUTION:The shape of a fuse 1 for laser trimming of a semiconductor integrated circuit device is formed slender and reciprocated one and a half times at a narrow pitch. If a laser is aimed at the central part 2 of the fuse 1, the part 2 of a fuse body 1 is cut. Accordingly, no problem occurs. On the other band, if the focus of the laser is deviated from the part 2 of the fuse, even if the part 2 of the fuse is not cut, the part of the same fuse disposed just adjacent thereto is out. Thus, even if the laser is deviated, it can be effectively cut.

Title: Shift lever
Inventor: HASEGAWA HIROYASU
IPC: F16H59/12
Filed: 1999-11-29
Abstract: PROBLEM TO BE SOLVED: To prevent a buttom coming off, and form a knob inexpensively by integral molding. SOLUTION: A pair of guides 38, 40 is extended from a tip part of a lever main body 12, a detent pin 18 provided in an end part of a cable 16 is arranged between the guides 38, 40 to be moved by guide of the guides 38, 40. Since the paired guides 38, 40 are inserted into a slit slot 28 of the buttom 26 inside a lateral hole 24, a wall part 44 is brought into contact with the guide 40 when the buttom 26 slides to the opening side of the lateral hole 24 by a prescribed amount. The button 26 is prevented thereby from coming off. Since the silding of the buttom 26 is limited by a guide 44, a wall or the like for limiting the slide of the buttom 26 is not required to be formed in an inner circumferential part of the hole 24. No undercut part is formed in the knob 20 when the integral molding is conducted.

Title: Multidirectional projection type screen device
Inventor: SATO KAZUTO
IPC: G03B21/00
Filed: 1999-11-29
Abstract: PROBLEM TO BE SOLVED: To obtain a multidirectional projection type screen device which produces projected images in the same form. SOLUTION: The image light projected from a projecting device 10 is partly reflected by a semitransmission plane 1 while the rest of the image light is transmitted and projected onto a screen 3. The projected light partly reflected on the semitransmission plane 1 is wholly reflected by a total reflection plane 2 and projected onto a screen 4. The image light to be projected onto the screen 4 is preliminarily mirror-reversed on the semitransmission plane 1 and again mirror-reversed on the total reflection plane 2. Therefore, the image projected on the screen 4 is in the same state as the image projected by the projecting device 10. The image projected on the screen 3 is produced by the transmitted light without inversion so that the image is in the same state as projected by the projecting device 10.  Thus, images without inversion can be displayed on a plurality of independent screens by using a single projecting device.

Abstract: PROBLEM TO BE SOLVED: To perform high quality gradation expression by varying a periodic interval of Vsync to a dot selected by a longitudinal electrode and a transverse electrode for a liquid crystal panel. SOLUTION: In a clock control unit 53 in an LCD controller 46 constituting a liquid crystal display system, a Vsync signal serving as a frame signal provided with a different periodic interval for each period is generated on the basis of the stored information in a Vsync pattern memory 54.

Title: Synchrotron radiation light generation device
Inventor: MATSUMOTO MANABU
IPC: H05H13/04
Filed: 1992-12-18
Abstract: PURPOSE:To raise evacuation efficiency. CONSTITUTION:A distribution type ion pump(DIP) 23 is disposed on an outer portion of charged particle orbit 13. Means of preventing light irradiation of DIP 23 is taken by eliminating a portion where light passes. And further, an absorber 31 for absorbing light passing to side wall of DIP 23 is disposed. Accordingly, because DIP is disposed at the position of a large gas source due to photodesorption, the evacuation efficiency is raised. Photoelectrons released from the absorber are contained within a cell of DIP, so that ionization of gas molecules is enhanced to raise the evacuation efficiency. In power connection in a low voltage region, the ignition delay is eliminated.
