Title: Washing device for semiconductor substrate
Inventor: FUJITA YOSHIMOTO
IPC: H01L21/304
Filed: 1989-03-28
Abstract: PURPOSE:To enable fine foreign objects, dust, etc., to be removed efficiently by rotary-driving a semiconductor substrate in both left and right directions and by spraying a fluid or a gas matching to the rotation onto the front and rear surfaces of the semiconductor substrate. CONSTITUTION:A semiconductor substrate 46 is supported by a rotary-drive pulley 43 and two supporting guide pulleys 42, rotation of a motor for rotary- driving wafer 41 is transmitted to the rotary-drive pulley 43 by the drive belt 42, thus enabling the semiconductor substrate 46 to rotate at high speed. Then, each fluid is sprayed out of a pressurized water, a chemical solution, and an inactive gas jet-out port 44 and is sprayed over the semiconductor substrate 46. Thus, the semiconductor substrate 46 is fitted vertically and the front and rear surfaces of the substrate 46 are washed simultaneously while being rotated so that the rear surface can be washed simultaneously. Also, foreign objects, dust, etc., separated from the semiconductor substrate 46 by the fluid drop effectively and do not remain on the surface of the semiconductor substrate.

Title: Post-processor
Inventor: HARA YOSHIYUKI
IPC: G06K9/68
Filed: 1983-04-28
Abstract: PURPOSE:To improve the reliability for the recognition of an input word in response to a monosyllable which is not stored in a dictionary by using a similar character table which is previously registered in case a monosyllable (character) which is not stored in the dictionary is fed. CONSTITUTION:The character (monosyllable) written to an input form 1 is recognized by a recognizing part 2 with the reference to a recognition dictionary 3. The result of this recognition is supplied to a word collating part 4. The Ln units of words 9 consisting of (n) units of characters serving as a word data base and a similar character table 10 are previously registered to a word dictionary 8 of the part 4. The result of recognition of the part 2 is supplied through a control part 5 of the part 4. When a candidate character which is not stored in the dictionary 3 is fed, the corresponding similar character is extracted out of the table 10 and stored in a candidate register 6. A comparator part 7 collates all candidate characters stored in the register 6 with the dictionary 9. Thus the input word can be accurately recognized.

Title: Gas turbine blade
Inventor: OKAMOTO YASUO
IPC: F01D5/18
Filed: 1983-04-28
Abstract: PURPOSE:To prevent occurrence of a crack in the through hole part of a front edge by providing grooves, which have opening parts perpendicular to a flow of high temperature gas, in the front edge part of a blade and also providing through holes which guide cooling air blow perpendicularly to the wall surfaces of said grooves. CONSTITUTION:A front edge part 31 of a gas turbine blade is provided with grooves 12, 13, which have opening parts nearly perpendicular to a flow of high temperature gas, and also provided with through holes 14, 15 for guiding cooling air blow perpendicularly to wall faces of said grooves 12, 13. Cooling air which flows in from the base part of the blade flows through a flow passage 2 and spouts out from through holes 14, 15 and, after dashing against wall surfaces of the grooves 12, 13, spouts outside the blade from the opening part. Thus, since the through holes, to which thermal stress is concentrated, are inside the groove and do not make direct contact with the high temperature gas, occurrence of a crack in the through hole part can be prevented.

Title: Transmission line
Inventor: SUZUKI YOUSUKE
IPC: H01P3/20
Filed: 1982-05-01
Abstract: PURPOSE:To attain the stabilized connection of a transmission line, by forming the transmitted part of electromagnetic wave surge energy using a dielectric into the physical state preserving the polarized plane of the electromagnetic wave. CONSTITUTION:The surge energy transmission part using the dielectric at least partly forms the physical state preserving the polarized plane of the electromagnetic waves toward the lengthwise direction. In this case, the physical state preserving the polarized plane is formed by providing at least one stripe slowing down the propagating speed of the electromagnetic wave surge energy toward the lengthwise direction so as to block the rotation of the electric field plane of the electromagnetic waves. Concretely, the lateral cross section of the surge energy transmission line using a dielectric is taken as an ellipse where the rate of the major axis L to the minor axis S is >=4/3. Or parts 4, 5 having higher density over the entire line are formed. Since the polarized plane is preserved, the connection of the transmission line is stabilized.
