Title: Photo-cvd equipment
Inventor: KARASAWA TAKESHI
IPC: H01L21/263
Filed: 1987-06-18
Abstract: PURPOSE:To make it unnecessary to remove a window for cleaning, by installing a reaction chamber and a cleaning chamber on both sides of a lamp chamber, and rotating the contaminated window to the cleaning chamber side to clean it, when a substrate in the reaction chamber is irradiated with ultraviolet rays through the window arranged in the lamp chamber to form a film and the window is contaminated. CONSTITUTION:A reaction chamber 1 accommodating a semiconductor substrate 2 is provided with a material gas feeding inlet 3, a discharging vent 4 and an inlet 3B to feed gas which restrain the film from attaching to a window and does not contribute to reaction. On the opposite side of the reaction chamber 1 with respect to a lamp chamber 12, a cleaning equipment 8 provided with a gas feeding inlet 9A for plasma etching and a discharging vent 9B is installed, and therein a discharging electrode 10 as included. In the lamp chamber 12 situated between the two chambers, a plurality of ultra-violet ray sources 6 provided with a reflector 7 behind them are arranged. A plurality of windows 5A, 5B situated between the ultra-violet ray sources 6 and the substrates 2 are constituted so as to be able to rotate toward the reaction chamber 1 side and the cleaning chamber 8 side by a driving equipment 13. When the window in use is contaminated, which is monitored by using a film thickness meter 11, the window is transferred to the chamber 8 side to be cleaned.

Title: Ultrasonic atomizer
Inventor: KAWAMURA TOSHIYA
IPC: B06B1/06
Filed: 1987-06-18
Abstract: PURPOSE:To prevent the instantaneous destruction of an ultrasonic vibrator at the time of no load operation, by limiting the current flowing to the ultrasonic vibrator at the time of no load operation by the resistor connected to the ultrasonic vibrator in series. CONSTITUTION:AC voltage is rectified in a rectifying circuit 12 and the output voltage of the rectifying circuit 12 is used as a power source in an oscillation circuit 13. The ultrasonic vibrator 14 driven by the oscillation circuit 13 atomizes a liquid. The resistor 16 connected to the ultrasonic vibrator 14 in series limits the current flowing to the ultrasonic vibrator 14 at the time of no load operation. That is, since the resistor 16 is sufficiently small to the impedance in a liquid of the ultrasonic vibrator 14 at the time of the usual atomization of the liquid, the current to the ultrasonic vibrator is not limited and no effect is exerted on an atomizing amount, and since the resistor 6 is sufficiently large to the aerial impedance of the ultrasonic vibrator at the time of dry burning, the current to the ultrasonic vibrator is limited by said resistor and the instantaneous destruction of the ultrasonic vibrator can be prevented.

Abstract: PURPOSE:To enable the press work with high accuracy preventing the buckling of a punch by piercing the necessary same point of a metal strip line with punching a punch over plural times in case of performing a press work of the lead frame with high density and of complicated shape. CONSTITUTION:The same place is punched over plural times in case of performing the press punching of the necessary pattern with feeding in order to the press die a metal strip 12 of the blank material of a lead frame. In case, for instance, of the width of a punch 10 being about 1/2 of the thickness of the metal strip 12, the same place of the strip 12 is punched in order each about 1/3 thickness a, b, c of the thickness of the strip 12 by each punch A, B, C.

Title: Method and apparatus for producing thermoplastic resin foamed body
Inventor: SHIRAI HIDETOMO
IPC: B29C47/00
Filed: 1982-08-31
Abstract: PURPOSE:To prolong the life of a flexible sheet and to form a foamed body efficiently, by putting on the flexible sheet a plastic net or the like, and allowing the flexible sheet to come in contact with the surface of an extrudate, with the combination of the flexible sheet and the plastic net attached to the exit of a decompression apparatus. CONSTITUTION:A thermoplastic resin composition that is melted and plasticized and is foamable is extruded through a mouthpiece, and is allowed to foam at a sizing die 2, a vacuum is applied to the extrudate 10 by the decompression apparatus 4 while it is cooled so that the extrudate 10 is further foamed to increase its volume, and the resulting high-foamed body is passed through the central opening 94 of the combination 9 located in the way of the high-foamed body to be taken out into the atmosphere. In this case, the extrudate 10 is forcibly moved to spread the opening 94 so that air is prevented from being included. As the combination 9 has the flexible plastic net (or a plastic film, or a cloth of natural or synthetic fibre) 92 on the side of the decompression apparatus, only the net 92 comes in contact with the extrudate 10 so that the sheet 91 is not abraded and therefore the forming can be effectively performed.

Title: Integrated element and wiring-layer forming method in integrated element
Inventor: MURAMOTO YOSHIFUMI
IPC: H01L23/522
Filed: 1993-06-23
Abstract: PURPOSE:To enhance the intrinsic performance of an integrated element sufficiently by forming a wiring layer on a gentle slant surface region in an acute angle shape at a semiconductor substrate. CONSTITUTION:Resist is applied on the entire surface of a photodetector layer 2, which is epitaxially grown on a semiconductor substrate 1. A resist mask 3 having the acute-angle parts is grown by a photo-process. Then, the resist mask 3 is used, and etching is performed. Thereafter, the resist mask 3 is removed. At the acute angle part of the photodetector layer 2, the step having the gentle slant surface is formed. Therefore, after a wiring pattern is formed on the slant surface by a photo-process, a wiring layer 4, which does not cross the step, is formed by Au vapor deposition and lift-off. In this way, the intrinsic performance of the element can be sufficiently enhanced when the integrated element is manufactured.

Abstract: PROBLEM TO BE SOLVED: To obtain an optimum estimation value, to improve correspondence between symbols and to improve reception quality by deciding the estimation values of a series of symbols transmitted through the use of an incoherent maximum likelihood sequence estimation MLSE system with an equalizer. SOLUTION: Regarding an incoherent transmission system, in the transmitter of a mobile radio telephone set, a mapper 4 generates a QPSK binary symbol a[k] and it is transmitted through a transmission channel 2 which hourly fluctuates a symbol [k] that is pre-coated by a differential coder 5.

Filed: 1990-06-13
Abstract: PURPOSE:To shorten waiting time when moving from a high-speed reproducing state to a standard-speed or slow reproducing state by holding a picture data under reproducing at high speed in a storing means until reproducing the next picture. CONSTITUTION:Each time reproducing and decoding the encoded data of a frame to which inter-frame encoding is executed, switching circuits 11 and 12 are changed over and the picture data of the next frame is generated from the picture data to be read from one of frame memories 9 and 10 and the reproduced and decoded inter-frame difference data, and written into the frame memories 9 and 10. When outputting the request of moving from the high-speed reproducing state to the standard-speed reproducing state, the encoded data is reproduced from the next frame of the display picture and decoded to prepare the picture data of the next frame. Therefore, since it is not necessary to reproduce and decode the encoded data having a large data amount, the waiting time from the request of moving to the standard-speed reproducing state to the execution of this reproducing is shortened, and standard-speed reproducing is quickly executed.
