Abstract: PURPOSE:To reduce a noise level, and to improve an S/N by placing and providing a digital amplifier and a digital volume, and an analog volume on the front- stage of a D/A converting circuit, and the rear-stage, respectively, and executing the gain adjustment by dividing it into the digital stage before the D/A conversion, and the analog stage after the conversion. CONSTITUTION:In case of setting the overall gain to a range of rated gains G-0dB, an analog volume 4 is set to zero dB being roughly through, and a digital volume 3b is controlled within a range of '0'--GdB. As a result, the gain of a variable gain circuit 3 of a digital stage is controlled to a range of G-OdB, and the digital means executes an operation being near a full bit, therefore, a noise level itself is small relatively. In case of setting the overall gain to a range of '0'--infinity dB, the digital value 3b is set to zero dB being roughly through, and the analog volume 4 is controlled within a range of '0'--infinity dB, and an attenuation is executed by the analog volume. In this case, to a digital processing circuit of a D/A converter 2, etc., a signal is inputted in a state that it is about zero dB and not attenuated, therefore, the S/N is scarcely deteriorated.

Title: Independent control robot for conveyance of semiconductor wafer and glass substrate
Inventor: FURUSAWA MASAZO
IPC: B25J13/08
Filed: 1997-08-12
Abstract: PROBLEM TO BE SOLVED: To secure a maximum throughput in shortening a span of stand-by time by attaching two robots separately to a bottom plate and a cover of a transfer chamber. SOLUTION: At the bottom side of a vacuum conveying chamber 1, there is a robot mounting opening part, and an independent control kinetic robot performing those of rotation, expansion or contraction and vertical motion is installed therein. This independent control kinetic robot performing these operations is installed in a cover 4 at the first stage of the vacuum conveying chamber 1 through an opening part being bored in a central part of this cover. In this cover 4, there are several pieces of dowel pins in the vicinity of an outermost perimeter of the cover at the atmospheric side separated from an O-ring, and with these pins used, a vertical robot axial alignment in front and in the rear of opening or closing of the cover and the highly accurate repeatability of a board retractable position from or to a process chamber 10 being shown to a vacuum robot 3 are securable.  Since the vacuum conveying chamber 1 becomes a state that a vacuum is maintained, when both covers 5 and 6 are put on the cover 4, the same high vacuum state as one cover alone is thus securable.

Title: Manufacture of soi substrate
Inventor: OKABAYASHI OSAMU
IPC: H01L27/12
Filed: 1989-09-07
Abstract: PURPOSE:To bond silicon substrates satisfactorily over their whole faces by a method wherein faces, to which oxide films have been applied, of the silicon substrates where oxide films on faces opposite to faces to be piled up have been removed and curved surfaces have been formed are put together, a prescribed heat treatment is executed and a bonded part of the oxide films is formed. CONSTITUTION:Regarding one silicon substrate, an oxide film on a face opposite to a face to be piled up is removed; faces, in a protruding state, to which oxide films 22 have been applied are faced and piled up; the silicon oxide films 22 are set to a state that they are brought into contact with each other only in the center of silicon substrates 21. When a temperature of the silicon substrates 21 is raised in this state, a rate at which the silicon substrates 21 are expanded is larger than that of the silicon oxide films 22 due to a difference in a coefficient of thermal expansion; as a result, a warp of the silicon substrates 21 is eliminated gradually. Thereby, a contact region of the silicon oxide films 22 of the two silicon substrates 21 is expanded gradually to a periphery from the center. While a gas is not confined between the substrates and a gap is not produced, the silicon substrates 21 are brought into contact on their entire surfaces and are bonded. Thereby, the substrates can be bonded without defects.

IPC: H01J37/08
Filed: 1987-09-14
Abstract: PURPOSE:To improve the reliability by fitting an arc cathode electrically floatingly in relation to a cathode pipe so that the negative potential can be applied. CONSTITUTION:When the discharge-forming gas 9 is fed through a cathode pipe 3 at the rate of 10cc or more per minute, for example, and the high voltage of 1KV or more, for example, is applied across a cathode disk 4 and a keeper electrode 1, a glow discharge is generated across the cathode disk 4 and the keeper electrode 1. If the negative voltage of about 10-100V is applied to an arc cathode 6 at this time, ions generated during the glow discharge hit the surface of the arc cathode 6 to heat it. When the temperature of the arc cathode 6 rises, thermo-electrons are emitted from the arc cathode 6, these electrons ionize the discharge forming gas molecules to generate ions, these ions again hit the arc cathode 6 to raise the temperature further. The temperature of the cathode 6 continues to rise, the thermo-electron current continues to increase and is balanced at the preset current value of an arc driving power source, and the discharge is continued even after a negative electrode 11 connected to the cathode 6 is cut off.

Abstract: PURPOSE:To accomplish high-speed rotation by providing a closed chamber formed between a magnetic fluid shaft sealing element disposed on high vacuum side and a solid shaft sealing element disposed on atmospheric pressure, which is exhausted by a vacuum pump. CONSTITUTION:A magnetic fluid shaft sealing element 9 disposed on high vacuum side comprises axially magnetized ring-shaped magnets 15 and ring-shaped magnetic poles 16 which are alternately disposed, wherein the knife edge-like inner peripheral portions of the magnetic poles are opposite to a shaft 5 formed of a magnetic body with a very small gap therebetween and a magnetic fluid 17 is retained like a ring in the gap. Further, a solid shaft sealing element 10 is disposed on the atmospheric pressure side of the magnetic fluid shaft sealing element 9, and a ring-shaped closed chamber 11 formed between the elements is exhausted by a low-vacuum pump 12. In this arrangement, as most of pressure of the atmosphere is retained by the solid shaft sealing element 10, it is not necessary to remarkably highten the density of magnetic flux passing through the magnetic fluid 17.

Abstract: PURPOSE:To accomplish inexpensive, easy-to-handle, display integral type reticles by making use of electric fields leaking from the end part of an electrode, forming a phase diffraction grating of field effect liquid crystal and providing an area acting on a liquid crystal layer as a reticle and an area acting as a display element. CONSTITUTION:Reticle transparent electrodes 3 and 4 and display element transparent electrodes 5 and 6 are faced and formed on glass substrates 1 and 2, and between them the liquid crystal layer 7 is held and sealed hermetically. This liquid crystal cell takes advantage of leak electric fields, and comprises an normally bright, easy-to-focus reticle. Without voltage impressed on the display element electrodes 5 and 6, the entire surface of the display part is uniformly black. When voltage is impressed on the electrodes 5 and 6, liquid crystal molecules turn, and the part corresponding to the displayed contents between the transparent electrodes 5 and 6 brightens. Since the same liquid crystal doubles as a reticle and a display, cell structure and its manufacture can be simplified.

Abstract: PROBLEM TO BE SOLVED: To reduce the construction cost of refuse pits, shorten their construction process and eliminate their trouble such as inundation in seafront areas, by shallowing them and facilitating their construction. SOLUTION: A refuse truck 4 on a refuse dumping stage 21 dumps refuse 6 into a front refuse pit section 2a.
