Title: System for transmitting lens information of camera
Inventor: SUMIO HIROSHI
IPC: G03B17/18
Filed: 1985-10-28
Abstract: PURPOSE:To transmit precisely the information of a photographing lens to a camera body by detecting the reflected light of light emitted from a light emitting element from a pattern by a light receiving element to transmit the information of the photographing lens to the camera body. CONSTITUTION:When the photographing lens 2 is loaded to the camera body 1, a label 4 is positioned immediately in front of a transparent cover 5. A beam radiated from each light emitting diode 6 is reflected in accordance with the information of each segment of the label 4 and made incident upon a phototransistor 7 and the information is read out. The resistance of the phototransistor 7 corresponding to the segment part with a high reflection factor is low and that corresponding to the segment part with a low reflection factor is high. When these resistance values are read out as binary signals of '1' and '0', code information such as '01001010' is obtained and different kinds of information for the photographing lens 2 can be distinguished by the camera body 1. Thus, the information of the photographing lens can be precisely transmitted to the camera body.

Title: Rotary compressor
Inventor: KAMITSUJI TOSHIO
IPC: F04C29/12
Filed: 1985-10-28
Abstract: PURPOSE:To effectively reduce the noise of a compressor by providing a valve port at a middle position between both the ends of a discharge chamber, and a discharge port at a nearly middle position on its one end to diminish the occurrence of an air column resonance in the discharge chamber. CONSTITUTION:Pressure pulsation occurring in a cylinder is chiefly damped by noise reduction effect produced by an air expansion in a discharge chamber 14. Since communication in the circumferential direction of the discharge chamber 14 is checked by bringing a portion 13a on the inside periphery of the side plane of a discharge cover 13 into contact with the outside periphery of a bearing journal 12a or approaching them each other, the air column resonance in a double cylindrical cavity can not occur. In addition to that, since a valve hole 12b on a bearing 12 and a discharge hole 13b on the discharge cover 13 are located near a middle and a quadrisection position between both the ends 14a, 14b of the discharge chamber 14 respectively, the discharge chamber 14 is hardly affected by the lower air column resonance. Consequently, the effect of the air column resonance is weak within an audible zone in the discharge chamber 14, and the extremely effective noise reduction effect can be therefore produced.

IPC: G06F17/50
Filed: 1993-09-28
Abstract: PURPOSE:To minimize the chip size of a semiconductor integrated circuit by calculating the minimum number of necessary level generators from circuit connection information, and changing connections from the level generators to blocks and generating optimized circuit connection information. CONSTITUTION:A circuit connection information optimizing process part 103 finds the total terminal capacity of all blocks connected to level generators belonging to an object type. Then the necessary irreducible number of level generators is found from maximum connectable capacity of the existent level generators and level generators which are as many as the found number are newly provided in the circuit connection information; and the connections are changed and the original level generators are removed. A similar process is repeated for all the generators, and then the process is ended. Namely, when the semiconductor integrated circuit is arranged and wired, the circuit connection information is optimized and then the arrangement and wiring are performed by the same method as before.

Filed: 1983-12-21
Abstract: PURPOSE:To shorten equivalently an access time per one word even if a memory element whose access time is slow is used, by reading out in parallel continuous 2K words along each axis shown by a three-dimensional logical address space. CONSTITUTION:Each line shows banks 0-3 of a memory bank, and each row is a physical address of a 4-bit portion in the bank. A number within in its drawing corresponds to a logical address. When each lower side 2-bit of logical addresses (p, y and x) is denoted as p1, p0, y1, y0, x1 and x0, respectively, the address assignment rule is bn={(a/4)+a}//4,ba=a/4, (a//4 is a surplus of the time when (a) has been divided by 4) when a bank number and a physical address of each bank are denoted as bn and ba, respectively, with respect to a=p1.2<5>+ p02<4>+y1.2<3>+y1.2<2>+x1.21+x02<0>, and as a result, as for four words continued in the three axes direction of the three-dimensional space, their bank numbers are different from each other, therefore, the access can be executed in parallel.

Abstract: PROBLEM TO BE SOLVED: To suppress a pseudo signal generated by photoelectric transfer with the light incident in a peripheral region in a photoelectric transfer region through an optical diffraction effect, by allowing a flat surface fringing the periphery of the photoelectric transfer region to be a silicide and specifying a light-incident region of the photoelectric transfer region. SOLUTION: A flat surface fringing the periphery of a photoelectric transfer region 14 is allowed to be a silicide, and the silicide region 32 specifies a light- incidence region (opening region) of the photoelectric transfer region related to a CMOS sensor of this structure. The silicide region 32 is provided on the surface of the photoelectric transfer region 14, so no gap where such light that causes smear is incident as diffracted ray exists. Thus, the incidence of light which causes smear is blocked in the photoelectric transfer region 14.

Abstract: PURPOSE:To prevent the crack of transmission windows by the heat of plasma by dividing the microwave transmission window for heat resistance disposed in proximity to the microwave transmission window for holding vacuum to plural constituting parts whose boundaries are brought into contact with the plasma. CONSTITUTION:Microwaves are introduced from a waveguide 2 through the transmission windows 3, 4 into a plasma forming chamber 1 to convert the gas introduced therein to the plasma in the plasma forming chamber 5 maintained under reduced pressure. A substrate is worked by the formed plasma 6. The microwave transmission window 4 for heat resistance made of alumina, etc., whose one surface is exposed in the plasma forming chamber 5 of the above-mentioned plasma device, is divided to the plural constituting parts 4a, 4b and is so formed that the greater part of the boundaries on which these parts are abutted covers the plasma 6 contact region. The microwave transmission window 3 for holding vacuum consisting of one sheet is provided in proximity to the upper part of the above-mentioned microwave transmission window 4 for heat resistance to avert the generation of the plasma in the spacing between both and to hermetically isolate the waveguide 2 from the plasma forming chamber 1. Thus, the generation of the crack in the two transmission windows 3, 4 is obviated even if the windows are heated by the plasma 6.

Filed: 1990-09-14
Abstract: PURPOSE:To prevent the water fall and overloaded operation of a feed water device provided with more than two pumps by foreseeing the water fall of the pump due to the lowering of the operating current of a motor and switching the operation to the other pump. CONSTITUTION:When power is supplied to a microcomputer MCON, an operating lower limit current IS, and a power upper limit current IL are read and stored into a memory M. The signal of the contact PS of a pressure switch 8 is then read, an on-off judgment is made, and its result is stored into the memory M. Whether feed water pressure is lower than the starting pressure is then judged, and in the case of being lower than the starting pressure P1, the operation of a pump 4-1 is started. The operating current I of a motor is measured and compared with the operating lower limit current IS. In the case of I being less than IS, the clocking of its time (t) is started. In the case of (t) exceeding tL, current abnormality is judged, and abnormality frequency NS is counted. At the third time of NS, a pump 4 is regarded to be abnormal, and its operation is stopped. After informing this failure by an alarm lamp, change-over to the operation of a pump 4-2 is performed.
