Filed: 1990-02-20
Abstract: PURPOSE:To constitute a power transmission path of less gears by changeably driving a rack constituting a pickup transfer mechanism and a rack constituting a disk loading mechanism with a common pinion. CONSTITUTION:In a disk loading process, a pinion part 26 of a driver mechanism 20 is meshed with a rack 42 of a slide member 4, and driving force of the driver mechanism 20 is transmitted via the power transmission path to the tray 5, and then a disk on the tray 5 is carried onto a turntable 10. Then, a power transmission path changeover mechanism is operated by receiving the power of the disk loading mechanism 2 just prior to completing the disk loading operation, and the power is transmitted to the pickup transfer mechanism 8. Consequently, the pinion part 26 is started to mesh with the racks 83 and 85 of the pickup transfer mechanism 8, while the pinion part 26 is released from meshing with the rack 42 of the slide member 4, thus changing the power transmission path automatically. By this method, the number of gears for constituting the power transmission path is reduced.

Title: Ultrasonic flowmeter
Inventor: NABESHIMA NORIYUKI
IPC: G01F1/66
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To make an ultrasonic flowmeter compact by reducing the influences of the upper stream and downstream of a fluid to be measured by directly finding the cross-sectional mean velocity of the fluid. SOLUTION: A fluid flows through a flow passage 4 having a rectangular cross section. The flow velocity of the fluid is measured from ultrasonic pulses passing through the ultrasonic wave propagating line 5 between ultrasonic transmitter-receivers 1 and 2. The fluid is made to form a two-dimensional flow in an x-y plane in the passage 4 by making the width of the passage 4 five times or more wider than the height H of the passage 4. The mean velocity of the fluid at the ultrasonic wave propagating line 5 becomes nearly equal to the cross-sectional mean velocity. The flow rate of the fluid is directly computed from the measured mean velocity at the line 5.

Title: Production of heating material for steel making
Inventor: NISHIDA SHINICHIRO
IPC: C21C5/28
Filed: 1989-02-21
Abstract: PURPOSE:To produce the heating material having excellent quality at a low cost by agitating and kneading carbon powder with a binder mixture composed of specific ratios of starch material and aq. caustic alkali soln. at the time of producing the heating material for compensation of melting heat of scrap to be used at the time of steel refining, and thereby producing the heating material. CONSTITUTION:Cold charges, such as a large amt. of inexpensive scrap, are used in addition to a molten iron, as raw materials at the time of refining the steel in a converter, etc., and, therefore, the heating material for compensation of melting heat at the time of melting by heating is produced by mixing 1 to 1.5wt.% the starch material, such as wheat flour and the aq. soln. of the caustic alkali, such as NaOH, as a binder with the carbon powder, and agitating and kneading the mixture by using a high-speed rotary vane mixer at a relatively low rotating speed of 7.5 to 8.5m/sec circumferential speed of the mixer rotary vanes. This kneaded matter is molded to a suitable shape and is dried to produce the heating material for steel making having a low moisture and high strength. Since the rotating speed of the rotary vanes of the is relatively low, the damage of the mixer itself is lessened and the heating material is produced at a low cost.

Title: Field effet control type bipolar power semiconductor device and its manufacture
Inventor: FURIITOHERUMU BAUERU
IPC: H01L29/45
Filed: 1989-02-21
Abstract: PURPOSE: To increase a latchup current of a bipolar power semiconductor element until it is largely immune to its latchup, by performing the conductive coupling of its individual cathode contact to its accessory n-region via the conductive layer extended between them on the surface of its substrate. CONSTITUTION: In a bipolar power semiconductor element, the creations of conductive layers 12, 13 are started from the stage wherein the doping of the inside of a substrate 1 exists and a gate electrode 7 is formed to cover its surface with a gate insulator 6. While an anisotropic etching is applied to the gate insulator 6, the gate insulator 6 present in the peripheral region of the electrode 7 is left and the one present under the electrode 7 is also conversed due to the ununiformity of the edge thicknesses of the gate electrode 7. Then, on the whole surface of this structure, metals are welded or deposited to form metal silicides with silicon.  Adjusting a tempering temperature so that the metal silicides are formed on both the substrate 1 and the gate electrode 7 made of polymerized silicon but not formed in the peripheral region of the SiO2 gate insulator 6 of the gate electrode 7, remaining non- reaction metals are removed therefrom by etching and an insulated SiO2 layer is welded thereon to metallize the cathode of the element thereafter by digging a contact hole through the insulated SiO2 layer. As a result, an n-region length X3 of the element can be shortened to make the latchup of the element remarkably preventable.
