Title: Magnetic head device
Inventor: HAYASHI HIROSHI
IPC: G11B5/265
Filed: 1985-03-25
Abstract: PURPOSE:To improve the symmetric property of a recording waveform, and to obtain a magnetic head device which scarcely causes a recording/reproducing error, by offsetting a leakage magnetic field from an erasing core. CONSTITUTION:A permanent magnet 9 is placed so that its magnetic field phi' passes through an I-shaped core 3 and an I-shaped core 5, as shown by a broken line. This magnetic field phi' has strength and a direction for just offsetting in the I-shaped core 3 a magnetic field phi generated in cores 5, 6 by an erasing direct current I which has leaked into the I-shaped core 3, and also the strength scarcely exerts an influence on the erasing capacity. Also, the magnetic field phi' passes through a magnetic disk 1, and passes through the I-shaped cores 3, 5 for recording/reproducing use and erasing use of a magnetic head of the upper side. To a winding of the erasing head of the upper side, an erasing current I is applied so that a magnetic field of the same direction is generated on the paper surface, and the magnetic flux phi' offsets an erasing magnetic flux, too, which leaks into the I-shaped core 3 for recording/reproducing use of a magnetic head 22 of the upper side. In such a way, mainly, the erasing magnetic field which leaks into the I-shaped core is offset, and the recording current and the recording magnetic field can be made to correspond to each other completely.

Title: Method and apparatus for forming fine film
Inventor: YAMAGUCHI HIROSHI
IPC: C23C14/46
Filed: 1984-03-28
Abstract: PURPOSE:To evaporate a desired material at an arbitrary fine position on a sample by selectively irradiating a plurality of targets by focussed ion beams through a deflection system and reattaching sputtering atoms generated by the irradiation onto the surface of the sample. CONSTITUTION:Ion beams 21 are lead out by a leading-out electrode 20 from an electric-field evaporation type ion source 19, and ion beams are focussed by an electrostatic lens system 22. Beams are deflected as shown in solid lines 25a by a deflection electrode 23 at that time, and projected to a target 24a in a lower section on the left and beams are sputtering-processed. Consequently, atoms 26a flying out by sputtering proceed toward a sample 27, and adhere on the sample by a reattachment phenomenon, thus forming a film. When an evaporating material is altered, a target 24b consisting of another material is fitted at a position on the side reverse to the target 24a, and deflection voltage is changed and beams are deflected toward the target 24b.

IPC: B65D83/36
Filed: 1981-04-20
Abstract: PURPOSE: To control the injection intervals of contained liquid surely by providing a limitor consisting of filter paper or the like which limits the permeation rate of gas phase to an intermittent sprayer for aerosol of insecticides, and opening and closing the  liquid phase passage by increasing or decreasing the air pressure in a pressurizing chamber intermittently.  
     CONSTITUTION: When the pressing force of the 1st stage is exerted to a stem 8, a projecting part 15 and a gasket 13 which are in contact with each other detach to communicate the gas phase part 11 of a vessel 2 and a lead-out hole 9, through which the gas phase flows into a gas phase passage 10 and flows into a pressurizing chamber 36 through a lead-out path 24, a lead-in pipe 27, and a flow limitor 26 consisting of felt, filter paper and open cellular synthetic resin or the like. When the pressure in the chamber 36 exceeds a set pressure, the central part of a pressing body 38 inverts strongly downward, thereby pressing a body 21 to be pressed aginst a spring 7. Hence, the stem 8 receives the pressure of the 2nd stage and separates the communicating hole 16 and the gasket 13, thence the liquid phase of the vessel 2 is indected through a nozzle 23. At the same time, the gas phase in the chamber 36 is discharged through a release port 45 and the body 38 restores the original shape. Since the body 21 restores the original shape as well, the injection of the liquid phase ceases and the inflow of the gas phase into the chamber 36 begins.

Filed: 1987-03-16
Abstract: PURPOSE:To render constant the supply of a substrate bias to a MIS transistor for the realization of reliable operations by a method wherein impurity concentration in a first semiconductor layer is so set that there will be no pinch-off in the channel section of a parasitic junction gate type transistor constituted of a semiconductor, a buried layer, and a second semiconductor layer. CONSTITUTION:A high-concentration (p<+>-type) region 2 is formed in the vicinity of a n-type buried layer 3 and, in particular, between the n-type buried layer 3 and a p-type epitaxial layer 4. A parasitic JFET is constituted of a p-type semiconductor substrate 1 and the p-type epitaxial layer 4 respectively serving as a source and drain, and the n-type buried layer 3 as a gate. When the JFET is operating in an normal manner, the bias voltage applied to the p-type semiconductor substrate 1 arrives at the p-type epitaxial layer 4 through this channel section. When a cell is in operation, there is a depletion layer in the vicinity of the n-type buried layer 3, and the channel section is narrowed as affected by the depletion layer. Along the interface between the n<+>-type buried layer 3 and high-concentration (p<+>-type) region 2, a high- concentration p-n junction region is constituted. Accordingly, the high-concentration (p<+>-type) layer 2 controls the depletion layer which emerges in the vicinity of the n<+>-type buried layer 3 in response to the substrate bias, the cell plate potential, and the substrate concentration.

Title: Optical scanning type displacement measuring instrument
Inventor: IGARI MOTOO
IPC: G01B11/00
Filed: 1987-03-14
Abstract: PURPOSE:To prevent the effect of the deviation of deflection means by providing light receiving systems arranged in the approximately symmetrical positions on both sides of the scanning surface of a light beam for collecting reflected light from an object to be measured by the light beam and position detecting sensors for detecting the positions of light receiving spots. CONSTITUTION:A light beam from a light projection source 1 is collected by a light projection lens and further scanned by a scanning mirror 4. The mirror 4 oscillates only in one direction and scans a plane formed by the light beam. Light receiving optical systems 6a and 6b are arranged in symmetrical positions on both sides of the plane and collect reflected light from an object 5 to be measured. Position detecting sensors 7 (7a, 7b) that can obtain current outputs corresponding to the positions of light receiving spots are arranged on the imaging planes of the optical systems 6a and 6b. Thus, when the irradiating position of the light beam is deviated, the movements DELTAX, DELTAX' of the imaging positions are generated in the sensors 7 and an output larger (or smaller) than an actual distance is obtained in the sensor 7a (or 7b). When the mean value of the distances obtained in accordance with the outputs, the deviations of the irradiating positions of the light beam are canceled each other out.
