Title: Formation of mask for x-ray exposure
Inventor: NOGUCHI FUMINOBU
IPC: G03F1/22
Filed: 1993-09-20
Abstract: PURPOSE:To provide a method for forming an X-ray exposure mask which can stabilize the intensity of alignment light regardless of the thickness of a translucent supporting film while allowing easy and positive alignment. CONSTITUTION:A supporting film 2 transmitting exposing X-rays and an alignment light beam is formed on the main surface of a silicon substrate 1 having the rear side formed with a protective film 3. A surface side antireflection film 4 for the alignment light and a patterned X-ray absorber layer 5 are sequentially formed on the translucent supporting film 2. The central part of the protective film 3 is then removed and the substrate 1 exposed on the rear side is etched to form a frame body having an X-ray transmission window and the translucent supporting film 2 is exposed on the rear side. An antireflection film 6 is then formed on the rear side on the exposed supporting film 2 thus forming a mask for X-ray exposure. This method protects the antireflection film on the rear side against corrosion due to hot alkali at the time of formation of frame body as compared with a conventional method thus sustaining the characteristics of antireflection film.

Title: Closed type compressor
Inventor: NONAKA RYUTARO
IPC: F04C29/00
Filed: 1988-09-16
Abstract: PURPOSE:To prevent wearing between a vane and a roller by providing the vane, coming into contact with the roller and sliding in a guide groove of a cylinder, and interposing ring materials of different coefficient of linear expansion between an eccentric part and the roller. CONSTITUTION:A clearance between an eccentric part 6 and a roller 7 is changed with a temperature of rotary compression element 4, changing a temperature in a follow-up manner to a change of pressure, by ring materials 18, 19, 20, 21 of different coefficient of linear expansion fitted to the periphery of the eccentric part 6, and friction torque rotating the roller is changed in a follow-up manner to forced contact pressure of a vane 11. By the respectively different coefficient of linear expansion, the friction torque between the eccentric part 6 and the roller 7 is changed in a follow-up manner to the change of the forced contact pressure of the vane 11 so that a revolving speed of the roller 7 on its own axis is in a fixed value in no relation to a change of a load. Consequently, an adapted part of the roller 7 to the vane 11 prevents uneven wearing of the roller 7, generated when its rotation on its own axis is stopped, and abnormal wearing between the roller 7 and the vane 11 generated when the revolving speed of the roller on its own axis is increased.

Title: Processing equipment for silicon substrate
Inventor: MIYAUCHI AKIHIRO
IPC: H01L21/304
Filed: 1989-09-11
Abstract: PURPOSE:To prevent fluorine from remaining on the surface of a silicon substrate after processing, and chemically stabilize the surface, by filling a hydrogen fluoride(HF) processing vessel with hydrogen gas. CONSTITUTION:A P-type silicon substrate 11 is arranged on a holder 12 made of teflon, and carried between HF water 13 and hydrogen gas 14. Hydrogen gas is introduced into a processing vessel 15 through a pipe 16. The vessel 15 is equipped with a synthetic quartz window 18 which transmits ultraviolet rays from a low pressure mercury lamp 17. After the silicon substrate 11 arranged on the holder 11 is dipped in the HF water 13, it is carried in an atmosphere of hydrogen gas 14, and irradiated with ultraviolet rays from the low pressure mercury lamp 17. Thus the substrate 11 is dried. This substrate subjected to the HF processing is sent to low temperature epitaxial process, as it is. Since an oxide film is not formed on the silicon substrate, high temperature process to eliminate the oxide film is unnecessitated, and epitaxial process at a low temperature is enabled.

Title: Digital camera
Inventor: KIDO TOSHIHITO
IPC: H04N5/00
Filed: 1996-09-03
Abstract: PROBLEM TO BE SOLVED: To prevent A/D misconversion due to phase delay of an image signal, when an image pickup part is connected to a camera main body part by a cable. SOLUTION: The digital camera consists of a camera main body part 2 and an image-pickup part 3 which is connected thereto by the connection cable 32. An image signal picked up by a CCD 303 in the image pickup part 3 is inputted to an A/D converter 205 in the camera main body part 2 through the connection cable 32 and converted from analog to digital. The image signal is read out of the CCD 303 in synchronism with a clock CLK1, generated by a timing generator 314 and converted from analog to digital in synchronism with a clock CLK2 generated by an A/D clock-generating circuit 203. The clock CLK2 is delayed by a delay circuit 204 behind the clock CLK1 by phase difference that the image signal has during connection cable transmission to prevent the deviation in the A/D conversion timing of the image signal due to the phase difference.

Title: Optical waveguide switch
Inventor: TANAKA KATSUKI
IPC: H01L31/02
Filed: 1983-12-14
Abstract: PURPOSE:To generate a gain for the light of a wavelength which is guided by arranging an optical amplifier in each branching path of an optical waveguide having plural branching paths and switching the excitation state. CONSTITUTION:Approximately uniform photoelectric power is distributed to two branching waveguide paths 3 and 3' from a main waveguide 1. The optical amplifiers 4 and 4' consist of a laser amplifying medium, and the medium is set to the excitation state by excitation from the external to generate a gain for the light of a wavelength which is guided, and it is outputted through output waveguides 5 and 5'. If the wavelength and the laser medium are selected properly, fairly intensive absorption is obtained. When the gain in the optical amplifier 4 is denoted as GdB and the absorption in the amplifier 4' is denoted as LdB, (-G+L)dB is attained as a crosstalk quantity observed in the output terminals of waveguides 5 and 5'. As the result, a high-speed optical switch is realized which does not required dimensions of an ultrahigh precision and has less crosstalk quantity.

IPC: F01P3/18
Filed: 1999-08-20
Abstract: PROBLEM TO BE SOLVED: To sufficiently cool electronic parts while the trend toward a large- sized duplex heat exchanger is suppressed. SOLUTION: A first radiator 110 for cooling the cooling water circulating in an engine, a second radiator for cooling the cooling water cooling electronic parts, and a condenser (SC condenser) integrated with a sub-cooler, are integrated in the upstream of the air flow of both the radiators 110, 120, and the second radiator 120 is arranged at a position which corresponds to the downstream of the air flow of the sub-cooler. Thus, since the air passed through the sub- cooler, the amount of heat radiation of which is smaller than that of the condenser core, flows into the second radiator 120, the temperature difference between the air flowing into the second radiator 120 and the cooling water passing through the inside of the second radiator 120 can be increased, and thereby the electronic parts can be cooled while the trend toward a large-sized duplex heat exchanger is suppressed.
