Title: Gallium nitride based semiconductor element and its manufacture
Inventor: FURUKAWA MASAKI
IPC: H01S5/00
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To reduce a consumption of a blade at the time of cutting prevent chipping cracks, and enhance a manufacturing yield, by a method wherein a groove of a wide width is formed on a reverse face of a substrate of a gallium nitride based semiconductor layer formed on the substrate, and a groove of a narrow width is formed in this groove, thereby forming a chip of the semiconductor layer. SOLUTION: After a reverse face of a substrate of a gallium nitride based semiconductor element is ground to form a thin substrate, a damage layer existing on a grinding face is etched, or a first groove is formed shallow by a blade of a great consumption amount, thereby preventing chipping and cracks. A second groove 7 of a narrower width than the first groove 6 is formed in this groove up to a depth of cutting the substrate, or up to a depth in which 20 to 30 μm remains from an element face. Thus, it is possible to enhance a manufacturing yield, additionally increase a cutting rate, reduce a consumption amount, and eliminate grind finishing after having ground the reverse face of the substrate. For this reason, it becomes possible to cut in response to a request for mass-production.

Title: Method of operating soot blower
Inventor: IGARASHI KOJI
IPC: F23J3/00
Filed: 1990-07-11
Abstract: PURPOSE:To suppress the generation of drain by supplying steam to an inner tube at the position to which an outer tube retreats and, then, moving forwards the outer tube and, after jetting out the steam from the jet nozzle at its tip end section, moving backwards the outer tube and at the same time supplying air to the outer tube. CONSTITUTION:In the stage before operating a soot blower a solenoid valve 2 is open and the steam flows from a steam piping 7 through the solenoid valve 2 and a needle valve 4 to the inside of the body of a soot blower 8. Next, an outer tube 10 is moved forward and the soot blower is operated, and the steam is jetted out from a nozzle 12. At this time a base valve 1 is open and the solenoid valve 2 is closed. The steam does not flow to the side of a three- way valve by a check valve 5. After the steam jetting is finished, the base valve 1 and solenoid valve 2 are closed, and the three-way valve is switched to the side of NC, and the air from the air piping 6 is sent to an air jet port 13 in an inner tube 9 to discharge and remove by a jet nozzle 12 the steam that is staying in the gap 15 between the outer tube 10 and inner tube 9. The soot blower stands by until the next operation.

Title: Cryogenic refrigerating machine
Inventor: FUJIMOTO SHUJI
IPC: F25B9/14
Filed: 1990-07-09
Abstract: PURPOSE:To shorten the cooling down time period and maintain the refrigerating capacity by a method wherein a cylinder assembly and a valve motor assembly are connected by two refrigerant pipes having different diameters and the two refrigerant pipes are alternatively changed over to each other depending upon the operating status. CONSTITUTION:In an expansion device 2, the high pressure gas supplied from a compressor 1 is adiabatically expanded to generate cold of a cryogenic level. The expansion device 2 is separated into two assemblies, a cylinder assembly 3 where gas is expanded in expansion chambers 18 and 19 in a cylinder 10, and a valve motor assembly 40. The cylinder assembly 3 and the valve motor assembly 40 communicate with each other by a first refrigerant pipe 60 and a second refrigerant pipe 61 having a smaller diameter. During cool-down operation, the cylinder assembly 3 and the valve motor assembly 40 communicate with each other by the second refrigerant pipe 61 having a smaller diameter. With an increase in the flow rate or refrigerant flowing in and out, the compression heat which is taken away at the low temperature end of the cylinder 10 is dissipated well by heat-exchanging with the refrigerant gas. When normal operating state is established, the first refrigerant pipe 60 having a larger diameter is opened so as to increase the operating capacity of a refrigerating machine.

Title: Tip part of endoscope
Inventor: TAKAHASHI CHOEI
IPC: G02B23/26
Filed: 1988-07-22
Abstract: PURPOSE:To obtain a distinct observation image by providing an illumination window and an observation window by protruding them independently each other from the tip part main body, and also, bringing a transparent thin film into contact tensely and closely with the surface of both said windows. CONSTITUTION:A part of an illumination light emitted to the outside from an illumination window 3 is transmitted by repeating a reflection into a transparent thin film 14. However, since the transparent thin film 14 is hollowed between both windows 3, 4, as for a light beam which passes through its hollow 14a, its optical path length is extended markedly and the transmissibility of a light beam which reaches four pieces of observation windows drops. Also, since the hollow 14a is asymmetrical, the illumination light which has been emitted from the illumination window 3 varies its advance direction in a process for passing through the hollow 14a, and the greater part thereof goes out to the outside of the film as a light beam A, or said light becomes a light beam having an angle at which it is not made incident on the observation window 4 as a light beam B. Moreover, as for the transparent thin film 14, its wall thickness is thin, therefore, in order that the illumination light is transmitted by repeating its reflection, the number of times of reflection becomes very frequent. Accordingly, even if there is an illumination light for reaching the observation window 4, its intensity is attenuated by repeating the reflection, and does not obstruct actually the observation image.

Title: Semiconductor acceleration sensor
Inventor: SAITO KAZUYOSHI
IPC: G01P15/12
Filed: 1994-07-15
Abstract: PURPOSE:To enhance the S/N of a semiconductor acceleration sensor by reducing the stress concentration at the shape-changing part between a deflection part and a supporting frame. CONSTITUTION:The thickness of a deflection part 12 is wholly uniformized, and the deflection part 12 is made up of a mass 121 and a narrow part 12i whose width is narrower than that of the mass 121. The width of the narrower part 122 is increased on the side of a supporting frame 11 for reducing the stress concentration at the shape-changing part or root part 123. Further, a detection element 19 is dislocated from the shape-changing part 123 to the mass 121 side by a distance OS. By this constitution, the stress at the shape- changing part 123 can be significantly reduced, to be less than the maximum nominal stress being detected by the detection element 19. Thus, even if the stress concentration is taken into consideration, the stress at the shape-changing part is less than the maximum nominal stress, and the deflection part 122 is prevented from being fractured at the root part 123. As a result, the maximum nominal stress can be set to a larger value, so that the S/N of a semiconductor acceleration sensor can be enhanced.
