Title: Searching method for cable break position
Inventor: KIMURA KEN
IPC: G01R31/02
Filed: 1978-08-09
Abstract: PURPOSE: To search the break position of a cable, etc., easily and efficiently by detecting the intensity of a current induced around a cable conductor by feeding a string of rectangular pulses to one terminal of the cable conductor in process of manufacture or winding.  
     CONSTITUTION: Rectangular-wave oscillator 6 is fitted to bobbin 5; a cable conductor where a break is predicted is connected to its output terminal 7 and other cable conductors are bundled and connected to output terminal 8. Then, cable 9 is rewound from bobbin 4 to bobbin 5 while oscillator 6 sends a rectangular pulse string signal to the cable conductor where the break is predicted. Electrode chip 13 where cable 9 penetrates is connected to the plus input terminal of detector 14 via a lead wire. The rectangular-pulse string signal flowing through the cable conductor provides a magnetic field around the conductor to induce a fine current through electrode chip 13, but provides no field beyond the break position, inducing no current. Judging from the swing of the index of the meter, the break point can therefore be found easily and efficiently.

Title: Ink-jet printing apparatus and ink-sucking mechanism
Inventor: HAYAKAWA MASAAKI
IPC: B41J2/18
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To flow ink smoothly thereby surely performing clear printing by promoting removal of air bubbles from an ink passage of an ink-discharging mechanism. SOLUTION: A flow velocity (u) of ink of an ink passage of an ink- discharging mechanism which is sucked by an ink-sucking mechanism is changed like a wave along a time axis. Specifically, a pump control part alternately switches a suction rate (v) at a pump part between V1 and V2 smaller than V1 along the time axis, thereby changing the rate like a rectangular wave. In this case, the flow velocity (u) of the ink at the ink passage of the ink- discharging mechanism is changed to form a smooth wave along the time axis. Removal of air bubbles present in the ink passage of the ink-discharging mechanism is accordingly promoted.

Abstract: PURPOSE:To simplify the operation for manufacturing wafer supporting boats by forming a slit groove communicating with the outside on a box side which faces the rear side of a supporting means so as to allow a part or the air flow passing said slit groove to pass through a gap between a supporting position and a wafer and to enter into the box. CONSTITUTION:A supporting boat has a structure that a cylindrical body 1A-1B whose openings of both ends are closed up by end plates 2 and 3 is divided into two along an axial direction. Also, a slit groove 4 is etched in the cylinder axis direction in the position on a radiation line displaced by about 30 deg. from a horizontal plane and a vertical plane which pass the cylinder axis. The lower half-cylinder 1A compsises L-shaped crystal bars 8 welded on each corner of its upper opening facing the upper half cylinder 1B. Furthremore, a half-circle crystal pipe 6 is fixed in parallel with a cylinder axial line direction in the position corresponding to the slit groove 4 of the internal circumferential plane of the lower half-cylinder 1A. The crystal pipe 6 comprises a wafer supporting through-groove 7 formed on its peripheral plane, and wafers 10 are aligned on the supporting grooves 7. Thus, the air flow can be diffused uniformly over the entire surface of the wafer and yields can be improved.

Filed: 1981-06-23
Abstract: PURPOSE:To automatically correct malfunction in positioning and to achieve correct positioning by comparing reproduced current address information with instruction address information, and moving an element for information recording or reproduction to an instruction address. CONSTITUTION:When an instruction address DA is received, the difference address SDIF between outputs DAR and CAR is compared with the prescribed value of a comparator 28 only for a short time. When the address SDIF is greater, an FF29 is set and the selector 27 selects the output CAR to move a carriage 6; when the address is less, the FF29 is reset and the selector 27  selects the output RCAR to further move the carriage 6. Then, when the outputs RCAR and DAR coincide with each other and the difference address SDIF  is reduced to zero, the FF29 is set and the selector 27 selects the output CAR. At the same time, the output RCAR coincident with the output DAR is set in a  current address register 17 and while the difference address SDIF is placed in  the zero state, positioning is completed in a settling time.

Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To make it possible to prevent a hanger from coming off even when a hanger bolt is slightly loosened by fittingly mounting a hanger which suspends a ceiling substrate on a reinforcing rib of a deck plate definitely. SOLUTION: This hanger comprises a horizontal member 3 and a hang bolt where the horizontal member 3 is provided with a horizontal plate and a slide plate 6. On inclined surface area 7A of the horizontal plate 5 is the length which fails to reach one reinforcing rib while a fit-in edge 5b, which is fitted into the other reinforcing rib, is formed at the tip of the other inclined surface area 7B. The slide plate 6 is slidably engaged with the inclined surface area 7A and is deformed toward the reinforcing rib along the inclined surface area 7A. When the horizontal member 3 is mounted on a deck plate, a fit-in edge 6b, which projects from the tip of the inclined surface area 7A is fitted in the reinforcing rib so that a locking portion 6c provided on the other end may come in contact with the hang bolt. Even when the hang bolt is loosened, the hang bolt prevents the movement of the slide plate 6 as long as it is engaged with the horizontal member 3 so that the hanger may not come off from the reinforcing rib.

IPC: H01L21/68
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a storage carrier for cleaning of a wafer of such structure that dummy wafers can not be drawn out easily so as to prevent the dummy wafers from mixing in product wafers. SOLUTION: An orientation flat part 11 is erected vertically in the storage groove 3 for accommodating a dummy carrier 10 in a storage carrier 1, and a dummy wafer 10 is inserted therein. Then, the dummy wafer 10 is rotated about 90 deg. so as to turn the orientation flat toward the open face of the storage carrier 1. The dummy wafer 10 is disabled to be drawn out because the width of the carrier groove in the diametrical direction of the wafer of the storage groove 3 is narrow by the difference between the diameter of the wafer and the diameter of the orientation flat part in the presence of a projection 5.
