Title: Floating magnetic head
Inventor: NAKAJIMA HIROMI
IPC: G11B21/21
Filed: 1993-10-14
Abstract: PURPOSE:To reduce fluctuation of the floating amount at the time of movement in the radial direction on a disk in respect to a floating magnetic head and also to increase the speed of the rise of floating when the disk is started. CONSTITUTION:Rail parts 1a are formed in a slider 1 on the opposing surface to the disk and grooves 11 are formed on side surfaces of the rail parts 1a which are faced to the downstream side of the air flow when the slider 1 is moved to the outer peripheral side of the disk and inclined against the direction of the disk movement. So, the negative pressure is produced by the air flowing into the grooves 11 when the slider is moved to the outer peripheral side of the disk, then the increase of the head floating amount is prevented. Since end parts 16, 17 at the reading sides of the rail parts 1a and a protrusion 13 are formed to the V-shape, the air flow is accumulated in the grooves 15 at the sides of the V-shaped parts to produce the positive pressure, then the rise up to the floating attitude is made fast, and a pitch angle in the floating attitude is increased.

Title: Field effect transistor and its manufacture
Inventor: UMEMOTO YASUNARI
IPC: H01L29/778
Filed: 1990-10-22
Abstract: PURPOSE:To enable a gate length and a source resistance to be reduced by placing a third semiconductor with a smaller sheet resistance than a first semiconductor and a higher carrier concentration than a second semiconductor at both sides of the first semiconductor and under the second semiconductor and then by connecting it to source and drain electrodes. CONSTITUTION:An undoped GaAs 36 and an undoped AlxGa1-xAs 3 are eliminated by wet etching and then a P-type GaAs 33 and an n-type GaAs 2 are eliminated by a CCl2F2 gas with a WSi gate electrode 5 and a side wall SiO2 9 and SiO2 9a as etching masks. An etching ratio of GaAs for AlGaAs can be secured to be larger than 1000, thus enabling the undoped AlxGa1-xAs 3 to remain near the gate electrode in an umbrella shape. Holes of GaAs after etching enter below the umbrella of the undoped AlxGa1-xAs 3 by approximately 500Angstrom  due to nearly anisotropic etching. A high-concentration n-type GaAs 4 which is doped with Si is allowed to grow selective by the MOCVD method (growth temperature: 700) with the WSi gate electrode 5 and side walls SiO2 9 and SiO2 9a as masks.

Abstract: PURPOSE:To prevent the drift of an electron beam for heating a metallic material by allowing a current flowing in a grounding line connected to a crucible contg. the material to flow in the opposite direction to the ionization current flowing from an ionization electrode to the crucible. CONSTITUTION:The electron beam from the injection port 11 of an electron gun is deflected by a deflection coil 12 in the (y) and (z) directions to follow a course 13, and injected into the vapor-deposition material 15 in a water-cooled copper crucible 14. The beam is further deflected toward the crucible surface by a magnetic field 19 generated by an electromagnet 16 to vaporize the material 15 in a specified pattern. The vapor current is ionized by an ionization electrode 17 and sent to a substrate (not shown in the figure) to form a thin film thereon. In this ion plating device, a grounding line 18 is fixed to the crucible 14 upwardly and vertically to the electrode 17, and the current flowing in the line is allowed to flow in the opposite direction to an ionization current I1. A magnetic field 20 generated by the current I1 is reduced by the generated magnetic field 31 to reduce its effect on the magnetic field 19. The drift of the electron beam is prevented in this way, and the beam is easily and surely controlled.

Title: Method for reducing vertical earth pressure on culvert
Inventor: UNNO YUSUKE
IPC: E03F3/04
Filed: 1996-10-25
Abstract: PROBLEM TO BE SOLVED: To reduce construction costs by providing an elastic cushion material between a base concrete in the earth and a culvert and embedding the culvert. SOLUTION: An elastic cushion material 3 made of elastic material such as polystyrene or polyurethane is placed on a base concrete 2 in the earth. And a box culvert 1 is embedded on the material 3. Since the height of an embankment on the culvert is low, the magnitude of the settlement of the culvert 1 can be relatively reduced. Since the cushion material 3 contracts, the difference in the magnitude of settlement due to the difference between the height of the embankment on the culvert and that of the embankment where there is no culvert can be absorbed by the cushion material. Thus no excessive vertical earth pressure is applied onto the culvert 1, and hence economical design can be provided without increasing the thickness of the culvert 1 and construction costs can be reduced.
