Title: Semiconductor wafer position corrector
Inventor: KIMURA YASUHIRO
IPC: H01L21/673
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To avoid producing dusts at positioning of a semiconductor wafer by using at least two rollers, each having a larger outer diameter than the aperture size of an orientation notch. SOLUTION: The position corrector for semiconductor wafers 1 rotatably holds each wafer with at least two rollers 2, and hence the wafer stably rotates. This prevents the wafer from contacting the inner grooves of a cassette 4 during rotation. The roller 2 has a larger outer diameter W1 than the aperture size W2 of an orientation notch 1a, resulting in that the roller 2 never contacts the end faces of this notch 1a and hence the dust is prevented from being produced due to contact of the roller 2 with the end faces of the notch 1a.

IPC: G06T11/20
Filed: 1978-10-19
Abstract: PURPOSE:To make desired information conspicuous to an operator among many pieces of information on display, by using negative characters for it. CONSTITUTION:A brightness inversion assignment code, if residing refresh memory 1, is detected by decoder 2 to set FF3. As a result, a brightness inversion indication signal changes from a low level to a high level and is supplied to exclusive- OR gate 5. Namely, when the brightness inversion indication signal is ''0'', display pattern data is outputted as it is, but when it is ''1'', the display pattern data changes from ''0'' to ''1'' or reversely and is outputted. The display pattern data of ''1'' makes a bright point on a screen, so that a point which is normally a bright point comes off while its back consists of bright points. In this way, negative characters are displayed.

Title: Ultrasonic wave direction meter
Inventor: IWASAKI MINEO
IPC: G01P5/00
Filed: 1997-05-01
Abstract: PROBLEM TO BE SOLVED: To detect a wave direction and a wave height accurately also for complex waves by passing the waveform of a detected flow rate through a digital filter instead of directly analyzing it. SOLUTION: A water pressure sensor 11 outputs the electrical signal of an analog water pressure waveform. The electrical signal is converted to a digital signal by an A/D converter 12, is stored in a data memory 14 through a processor 10, and at the same time harmonics that are equal to or more than 0.1 Hz are converted to an emphasized and corrected water pressure waveform by a second digital filter 13 as frequency increases. Included high-frequency components are stored in the data memory 14. Ultrasonic transducers 15a-15d measure the east/west and south/north components of a flow rate, inputs them to a first digital filter 19, and store the corrected east/west and south/north components in the data memory 14.  The processor 10 reads the high-frequency component of the peak value from the data memory 14 and decides the wave direction of a high-frequency wave from the vector value of the high-frequency component of the flow rate that is obtained when the high-frequency component is at the maximum. Wave direction and wave height are stored in the data memory 14.

Title: Heat transfer tube and manufacture thereof
Inventor: KUWABARA HEIKICHI
IPC: F28F1/40
Filed: 1985-06-14
Abstract: PURPOSE:To provide the heat transfer tube having heat transfer surface structue, high in heat transfer coefficient and durability, and the inexpensive manufacturing method thereof by a method wherein the shape of the section of protuberance, provided in the tube, is constituted of a circle or a smooth curve like the circle at the bottom surface and an arbitrary height while the protuberances are arranged in the tube regularly along a spiral curve. CONSTITUTION:The protuberances 3 are formed on the inner wall surface 1 of the heat transfer tube along the spiral curve. The section of the protuberance 3 is circle or ellipse. When single-phase fluid, having no phase change, flows through the tube, the fluid 60 at the central portion of the tube flows into the axial direction of the tube, however, the flow direction of fluid 61, near the wall surface of the tube, is curved and a part thereof generates vertical vortex having the rotating axis thereof in the axial direction of the tube when it flows through gaps between protuberances. In the transversal section of the tube, the stream line is not curved suddenly when the flow collides against the protuberance since the protuberance is provided with a curvature, therefore, effect of corrosion due to the shear stress of the fluid may be small.

Filed: 1987-05-27
Abstract: PURPOSE:To insert a semiconductor device in a magazine without causing defects by providing a pair of magnetic poles with different polarities facing each other and by inserting the semiconductor device in the magazine interposed between the magnetic poles. CONSTITUTION:A semiconductor device 7 sent to the end of a linear feeder 6 is vacuum sucked by a nozzle 11. The rotation of a rotor 9 causes a swing arm 8 to turn one-half and the nozzle 11 to rotatebly move toward the side of a magazine holder 14, thus inserting the semiconductor device 7 in a magazine 16. The semiconductor device 7 thus inserted is maintained horizontal in a floating condition in the air due to a magnetic force which a lead 7a consisting of magnetic material receives between magnets 15a and 15b. Similarly, the semiconductor device 7 is inserted in the magazine 16 by the nozzle 11 on the side of the linear feeder 6. Although the first semiconductor device 7 is forced down by inserting the second semiconductor 7, an excessive force is not exerted against the semiconductor device 7 during its downward push, since it is only retained by magnetic force, thereby preventing the occurrence of defects such as cracks and nicks.
