Title: Production of base disk for optical recording medium
Inventor: YOKOYAMA RYUICHI
IPC: G11B7/26
Filed: 1986-12-01
Abstract: PURPOSE:To suppress intrusion of air bubbles into a curable resin by superposing a mold on which the resin is coated on a substrate in such a manner that the coated surface is faced downward and parting the united substrate and curable resin together from the mold. CONSTITUTION:A stamper 1 is superposed on the substrate 3 in such a manner that the curable resin (resin 2 curable when imparted with energy) coated on the surface thereof is faced downward. The substrate 3 and the resin 2 are then brought into point contact with each other without spreading the resin 2 and thereafter, the contact surface is gradually expanded. The resin 2 is further dropped or coated on the substrate 3 side as well and the stamper 1 and the substrate 3 are so superposed that the resins 2 contact each other first. The face to face contact is thus substantially prevented. The substrate is thereby laminated on the stamper with substantially no intrusion of the air bubbles into the resin, by which the base disk having a low error rate is produced at a high yield.

Title: Clamp mechanism for floppy disk device
Inventor: NAKAMURA NORIO
IPC: G11B17/028
Filed: 1986-11-29
Abstract: PURPOSE:To prevent the damage of a disk at the time of clamping by forming a clamper so that a tip part composed of respective tips of plural side surface members can be inclined at a prescribed angle to the surface of the disk, fitting the tip part to the central hole of the disk and pressing the disk to the spindle hub of a spindle mechanism. CONSTITUTION:A tip part 21 of a clamper 20 is fitted to a central hole 14 of a disk 10 and the disk 10 is clamped to a spindle hub 11. Since the surface of the tip part 21 facing to the central hole 14 of the disk 10 is inclined, it is brought into contact gradually from the part closest to the tip part 21 with the inner circumferential part of the central hole 14. Consequently, even while the disk 10 is not rotated, by the contacting of the tip part 21, the inner circumferential part of the central hole 14 is not damaged, the tip part 21 is smoothly fitted to the central hole 14 and the disk 10 is rotated without fail while it is clamped to the spindle hub 11. For this reason, the event in which the disk 10 is rotated in the eccentric condition can be prevented.

Title: Coil integral distributor
Inventor: ITO SHOJI
IPC: F02P7/04
Filed: 1989-11-02
Abstract: PURPOSE:To secure such a highly reliable coil integral distributor as improved in cooling capacity of a coil by installing a flow hole, convecting ambient air, in a cooling metal sheet attached to a coil core. CONSTITUTION:A metal sheet 10 is installed in a coil core 9 as its cooling use, thereby constituting it so as to radiate heat to a low temperature housing 1 from a coil 15 by means of heat conduction. Then, each of flow holes 16a, 16b for a convection of air around the metal sheet 10 is installed, through which air in the inner part is made so as to be convected. In brief, since an A part nearer to the coil core 9 comes to high temperature from a B part at the side of a cap 5 in a space around the metal sheet 10, air in the A part flows out into the B part by way of the flow hole 16a. With this constitution, air in a lower part C of the metal sheet 10 flows into an upper part, so that air in the metal sheet 10 and a D part of the cap 5 flows into the metal sheet 10 by way of the flow hole 16b. Thus, the metal sheet 10 can be cooled by a convection current being shown in these arrows.

Title: Satellite wave capturing system for gps receiver
Inventor: ANDO HITOSHI
IPC: G01C21/00
Filed: 1989-11-02
Abstract: PURPOSE:To enable a satellite to be quickly re-captured when a state is returned to a receivable state again by switching a reception mode so that only the satellite at a position with the maximum angle of elevation predicated at a time when the reception of a satellite wave is disabled can be captured. CONSTITUTION:When a vehicle progresses to a tunnel, etc., and a state where no satellite can be captured is continued for a prescribed time, the capturing operations of the satellites S1-S4 are interrupted. Simultaneously, it is calculated which satellite is the one at the position with the maximum angle of elevation predicted at that time. Assuming that the satellite at the position with the maximum angle of elevation is the satellite S3, a GPS receiver switches the reception mode so as to capture only the satellite S3 at the position with the maximum angle of elevation, and performs the capturing operation of only the satellite S3. When the satellite S3 at the position with the maximum angle of elevation is captured, a re-captured satellite S3 and another three satellites obtained from the almanac information of the satellite S3 and most suitable for a three-dimensional measuring position at that time are selected, and the ordinary sequential multiplex reception of those four satellites are started, and when the capture of the satellite is disabled, the satellite at the position with high angle of elevation is re-calculated, and after that, the re-capture is repeated.

Title: Ultrasonograph
Inventor: KAMIYAMA NAOHISA
IPC: A61B8/00
Filed: 1998-10-07
Abstract: PROBLEM TO BE SOLVED: To observe even information on the depth direction in a manner relatively close to diagnosis with a normal two dimensional diagnostic device and make an accurate diagnosis easily by employing a display method where a three-dimensional image stands out in a display where a tomogram is a major element. SOLUTION: A tomogram indicating an echo brightness of picture quality higher than a normal device is displayed by two-dimensionally scanning a single plane under scanning conditions higher than a normal two dimensional ultrasonograph. By carrying out an operation to gain three-dimensional information about a three dimensional area smaller than the scanning range of a normal three dimensional ultrasonograph, three-dimensional image of an area including at least a tomogram is obtained, and the three-dimensional image is superimposed on the tomogram and displayed. Thus in a display where a tomogram is a major element, a display method by which a three-dimensional image stands out thereon is used. As the display of a tomogram is a main function and the three-dimensional scanning range is smaller than normally, real time observation is possible.

Title: High breakdown strength mos semiconductor device
Inventor: TANAKA SOICHIRO
IPC: H01L29/78
Filed: 1990-10-23
Abstract: PURPOSE:To improve the breakdown strength of a MOS semiconductor by providing an electric field concentration relieving region of the same conductivity as those of a drain and offset drain regions at the boundary section of the drain regions. CONSTITUTION:An electric field concentration relieving region 12 is provided at the boundary section of a drain an offset drain regions 6 and 7. Because of the area 12, the radius of curvature of the periphery of the bottom section of the drain region 6 becomes substantially larger and the concentration of electric fields to the bottom section of the region 6 is relieved. In other words, the drain is constituted to a three-stage structure of the n<+>-type region 6, n-type region 12, and n<->-type region 7. Accordingly, the controllability of the breakdown strength can be improved, since it is possible that the breakdown strength can be decided by the edge of the offset drain region 7. Therefore, the breakdown strength can easily be improved by lowering the impurity concentration of the offset drain region 7.
