Title: Method for erasing magnetism
Inventor: SOGA TAKASHI
IPC: G11B5/024
Filed: 1986-02-07
Abstract: PURPOSE:To erase free from residual magnetism by setting erasing current to an initial saturation current value 1-2 times an optimum recording current value sufficient to saturation magnetizing tracks, and setting a period of attenuation in which attenuation is caused from the maximum amplitude to about 5% to a time 30-60 times that of track scanning period. CONSTITUTION:Polarity of erasing current 1 alternates at every period TP, and amplitude decreases gradually exponentially. When the period in which a magnetic head makes one round scanning of track is denoted as TS, TP>=TS is established. When such erasing current 1 is allowed to flow in the coil 4 of the magnetic head 3, polarity alternates every TP at any point on the track with rotation of the disk as TP>=TS, and a magnetic field of longitudinal direction of the track in which amplitude decreases gradually operates. In this case, the minimum value I of erasing circuit 1 in initial period is made to a value sufficient to generate a magnetic field that can magnetize the disk 2 to saturation level. Thereby, magnetic flux is saturated once and then converges to a magnetic neutral point in a loop.

Title: Receiving method of ultrasonic type remote controller
Inventor: TAKEDA MASAAKI
IPC: G08C23/02
Filed: 1983-02-15
Abstract: PURPOSE:To increase the tolerance of a constant which determines the gain of a reception part and to facilitate an adjustment by deciding a pulse signal which appears in a time zone except a gate time as a significant signal only when its width is larger than a specific value. CONSTITUTION:When a signal R to be discriminated is low at a sampling point, the sampling operation is held standby until the next sampling point. When the signal R to be decided at a high level, a set signal S is held at the low level only instantaneously to set a state signal Q to the high level. When the signal R goes down to the low level in said state, the signal Q also drops to the low level, so a discriminating controller 5 decides its level at the next sampling point to realize that the signal R continues for one period of a sampling signal F. When the signal Q is at the high level continuously, the operation is held as it is until the next sampling point, and it is decided that a normal pulse P arrives when the signal continues for three periods of the signal F. When the signal Q falls to the low level within three periods of the signal F, the signal is regarded as a reactive signal.

Title: Plasma process equipment
Inventor: INOUE TAKU
IPC: H01L21/3065
Filed: 1987-02-03
Abstract: PURPOSE:To equalize plasma density distribution, and to form a film in uniform thickness or enable treatment such as etching by shaping a plurality of cusp fields into a sample chamber by a plurality of permanent magnets. CONSTITUTION:Permanent-magnet structures 6 formed to a short cylindrical shape are disposed around a base plate 5 and a sample S placed onto the base plate 5 approximately concentrically to the sample S so as to surround the peripheries of the base plate 5 and the sample S placed onto the base plate 5 extending over the predetermined width of the upper and lower sections of the sample S including the base plate 5 and the sample S placed onto the base plate 5. Consequently, a magnetic field shaped between permanent magnets 6b adjacent in the circumferential direction forms the so-called multi-cusp fields where the lines of magnetic force shape sharp points at regular intervals in the circumferential direction, and the magnetic-field distribution strength of the peripheral section of the sample S is increased as a whole. Accordingly, electrons in plasma are confined by strong magnetic fields by the cusp fields of a plasma surface in a sample chamber and ionization efficiency can be improved, and the density distribution of plasma is equalized in a space having a weak magnetic field shaped surrouned by the cusp fields, thus making throughput speed such as the speed of film formation, an etching rate, etc., uniform.

Title: Three-dimensional measuring method and apparatus therefor
Inventor: KAWAI SHIGERU
IPC: G01B11/25
Filed: 1985-02-13
Abstract: PURPOSE:To prevent the generation of high-order moire fringes, by bringing the amplitude transmissivity of a lattice to a sine wave form. CONSTITUTION:A reference lattice 3 is constituted by using a material perfectly same to that of an observation lattice 6 and the amplitude transmissivity thereof is a sine wave form. This sine wave form lattice can be prepared by the interference of two plane waves. In the three-dimensional measuring apparatus of this constitution, the light of a white light source 1 is collimated by a collimating lens 2 and the image of the reference lattice 3 is formed on matter by a condensing lens 4. The lattice pattern deformed corresponding to the shape of the surface 9 of the matter 9 is passed through a condensing lens 5, the observation lattice 6 and an image forming lens 7 to recorde moire fringes between the observation lattice 6 and the surface 9 of the matter by a camera 8. Because the same sine wave form lattice is used as the reference lattice 3 and the observation lattice 6, no high-order moire fringes are recorded and desired moire fringes can be measured.

Abstract: PURPOSE:To easily prepare a strong acid type cation exchange substance having inclusion action, by reacting monohalogenoalkylsulfonate with polycyclodextrin resin. CONSTITUTION:Usually, 0.5-5pts.wt. per 1pts.wt. of polycyclodextrin resin of monohalogenoalkylsulfonate is added to an aqueous alkaline solution in which the polycyclodextrin is dispersed under stirring and both reactive components are reacted under stirring while the temp. of the reaction liquid is held, for example, at about 40-60 deg.C to easily obtain polycyclodextrin into which a predetermined sulfoalkyl group is introduced.
