Title: Method for data processing of synthetic aperture radar
Inventor: MORIMOTO SHIGERU
IPC: G01S13/48
Filed: 1984-07-11
Abstract: PURPOSE:To obtain a processing method further enhanced in azimuth angle determination accuracy, by forming two synthetic aperture beams so as to have a sharp notch at the time of the imaging processing of an echo signal and determining an azimuth angle by utilizing said notch. CONSTITUTION:The echo signal from an object obtained by synthetic aperture radar is preliminarily received and recorded and imaging processing is performed on the basis of this recording data by a correlation method. At this time, a reference function for forming two main beams (synthetic aperture beams) 2-1, 2-2 forming a sharp notch (null) N is fabricated. The echo signal and a transmission wave are subjected to operation processing on the basis of the reference function while taking correlation to form two main beams 2-1, 2-2 for synthesizing the sharp notch N equivalently. If there is an object in the notch direction, the image of the object is erased from an image and, therefore, the azimuth angle of the object is determined from this phenomenon.

Title: Cryo-expansion device
Inventor: MORISHITA HIROYUKI
IPC: F25B9/14
Filed: 1989-06-05
Abstract: PURPOSE:To restrict a temperature rise of sliding heat of a piston ring and to reduce an amount of wear of the sliding part by a method wherein the sliding part of the piston ring of a piston is provided with a cylindrical liner composed of material having a high thermal conductivity. CONSTITUTION:Sliding parts of each of piston rings 5 and 5, i.e., inner surface of a cylinder 1 are provided with a cylindrical liner 12 composed of material having high thermal conductivity such as aluminum or copper or the like. This liner 12 is formed such that a separate member is press fitted or installed at the inner surface of the cylinder 1 through adhesion or formed to a predetermined thickness at the inner surface of the cylinder 1 through plating or vapor deposition or the like. Each of the piston rings 5 and 5 of a slacking piston 2 and a displacing element 3 is reciprocated and slid at the inner surface of the cylinder 1. A sliding heat generated by this operation is released in a longitudinal direction through the cylindrical liner 12, so that a temperature at the sliding part can be prevented from being increased. Accordingly, even if the cylinder 1 is made of stainless steel having a low thermal conductivity in order to prevent a thermal entrance from a surrounding releasing part to a heating stage 11, it is possible to reduce an amount of wear at the sliding part.

Title: Photographic flash device
Inventor: KOJIMA SUZUO
IPC: H05B41/36
Filed: 1978-11-17
Abstract: PURPOSE:To eliminate the need for trigger transformers and make photo detecting circuit simple by triggering a 2-terminal switching element subordinately through triggering of a 3-terminal thyristor thereby turning a main thyristor OFF. CONSTITUTION:When the shutter of the camera is pushed and a main thyristor 4 is triggered, a discharge tube 3 emits light. When the flash quantity becomes the equantity necessary for the sensitivity of the film, a 3-terminal thyristor 10a is triggered and is turned OFF by a photo detecting circuit 14b. This causes the charging voltage sum of the capacitors 1, 6 to be applied to the loop of the main capacitor 1, reactor 2, 2-terminal switching element 20, commutating capacitor 6 and thyristor 10a, by which the element 20 is subordinately triggered and the thyristor 4 is turned OFF. Hence, the main thyristor is turned OFF by one set of photo detecting circuit without using any trigger transformer, thus the commutating circuit becomes of the simple constitution and operates surely.

Title: Method and apparatus for reduced pressure processing
Inventor: KAWASAKI YOSHINAO
IPC: H01L21/67
Filed: 1986-06-20
Abstract: PURPOSE:To improve the yield of samples without reduction of the operating efficiency of the apparatus by carrying a sample into and out of a processing chamber through separate lock chambers, and providing a process in which rapid leakage from reduced pressure is performed and evacuation is immediately executed under the no-sample state. CONSTITUTION:A load cassette 1 and an unload cassette 2 are present in the air, and a substrate 3 is carried into a load lock chamber 4 and conveyed to a processing chamber 7 by an arm 6 in a sub-vacuum chamber 5. After being processed, it is conveyed to an unload chamber 9 by an arm 8, and taken out into the air and received in a cassette 2. Before an unprocessed substrate is carried in, a valve 20 is opened in the chamber 4 to rapidly leak the reduced pressure, thereby making the dusts deposited to settle in the chamber swirl upward, and the chamber is immediately evacuated and cleaned. Similarly in the chamber 9, the rapid leakage and evacuation process is repeated after the passage of the substrate, thereby cleaning the inside of the chamber. Since the lock chamber 9 can always be kept clean, the yield of samples improves without reduction in operating efficiency of the apparatus.

Abstract: PURPOSE: To detect trouble exactly in a short time by the procedure in which the connection time of thyristor composing thyristor Leonard device is detected and then when the time continued over a fixed hour, a trouble signal is sent out.  
     CONSTITUTION: The motor M is driven by the thyristor Leonard device 1, the light connection device 14 is connected through the rectifier circuit 13 to the thyristors D 1  and D 2  of each arm, and the output from the device 14 is applied to the transistor 26 through the resistor 6, the capacitor 18, and the Zener diode 19 to energize  the detection relay 27. Thus, when the thyristor is connected, the output of the light connection device 14 is stopped and the capacitor 18 starts charging. When the charging continues over a fixed hour and the voltage becomes higher than the voltage of the Zener diode 19, the transistor is connected to detect trouble, and therefore trouble can be discovered in shorter time than the connection time of thyristor.
