Title: Deposition method for titanium oxide film, and manufacture of semiconductor laser
Inventor: MIYANAGA RYOKO
IPC: H01S5/00
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To stably manufacture a titanium oxide film of high deposition rate and low-absorption coefficient by using a metal titanium and electron cyclotron resonance plasma for specific deposition pressure. SOLUTION: An electron cyclotron resonance(ECR) plasma is used for deposition of a titanium oxide film. A metal Ti is used as the material for titanium. Film-formation is executed with the pressure inside a deposition chamber 102 to be 0.1 Pa or below. The surface of a target is cleaned before film-forming under such condition as with less flow rate of oxygen gas. With this configuration, the deposition pressure of 0.1 Pa or less enhances ionicity, for efficient release of Ti from a target surface. Since the target surface is cleaned under such condition as with less oxygen gas flow rate before film-forming, the surface of Ti target is always at a specified condition, in short a clean surface with less impurities stuck, so the film-forming condition is stable.

IPC: B29C39/10
Filed: 1981-11-12
Abstract: PURPOSE:To enable preventing of the occurrence of a partial void in a face plate part through a specific simple implanting control, by a method wherein a plate surface is positioned erecting in a perpendicular direction, a solid resin liquid is implanted into a lower part of a hollow outer body to foam-in-place it. CONSTITUTION:A solid resin 8, implanted into a lower part of the inside of a hollow outer body A, grows into foaming with the passage of time and is brougt into a cubic expansion. The solid resin liquid 8 has a larger mass than that of air and its surroundings are encircled with face plates 1 and 2 and edge plates 3-6, and thereby with the gowth of foaming, the inside of the hollow outer body A is gradually filled as shown in virtual lines A, B, C.... As a result, air in the hollow outer body A is prevented from being partially left with the aid of the face plates 1 and 2 and rises. Most of it flows to the outside through an overflow part 1, and the rest flows outside through connections between the face plates 1, 2 and the edge plates 3, 6.

Title: Method for controlling fast breeder plant
Inventor: TAMANO TOYOMI
IPC: G21D3/08
Filed: 1989-07-14
Abstract: PURPOSE:To relieve the overheat which a reactor vessel receives and to prolong the service life of the reactor by providing a flow passage for bypassing an intermediate heat exchanger in a secondary sodium Na system and controlling the flow rate of the bypassing flow passage at the time of tripping. CONSTITUTION:Primary and secondary Na pumps 6,7 are tripped by the generation of a plant trip and the flow rate of the Na begins to coast down, but the secondary Na system 5 is longer in overall length than the primary Na system 7 and has a large fluid inertia and, therefore, the response of the decrease in the flow rate delays. A bypass valve 12 of the intermediate heat exchanger is, thereupon, opened in order to detect 13 the deviation in this flow rate and to decrease the same, then the Na of the Na system 5 flows partly to the bypass flow passage 11 and the inflow rate of the intermediate heat exchanger 4 on the secondary side decreases correspondingly. The difference in the flow rate between the primary and secondary Na of the exchanger 4 is thereby averaged and the drop of the primary outlet tempt. is suppressed. The increase of the primary outlet temp. which takes place right after the tripping is suppressed as the valve 12 is closed. The overheat that the reactor vessel receives is relieved in this way and the life of the reactor 1 is prolonged; in addition,the soundness and safety of the plant are improved.

Title: Magnetic disk device
Inventor: KIMURA MASAYUKI
IPC: G11B21/21
Filed: 1984-08-31
Abstract: PURPOSE:To eliminate so-called thermal off-track phenomena that occur when there is a temperature difference between the times of recording and reproducing information and to reduce malfunction by making the shape of the arm of a magnetic head linearly symmetric both in the longitudinal direction and direction of plate thickness. CONSTITUTION:The temperature in the sealed case at the time of recording and reproducing information and the temperature of a magnetic head 5 sometimes differs larger than the temperature difference caused by a difference in working ambient temperature and a difference in time in which a spindle 1 is driven by a motor. Here, the shape of the arm 5a is made linearly symmetric in the longitudinal direction V-V and in the direction of plate thickness W-W of the arm 5a. Accordingly, deformation of the arm 5a such as thermal camber and torsion does not occur in the magnetic head 5, and thermal off-track phenomena due to thermal deformation of the magnetic head do not take place even when the temperature difference is large between the time of recording and reproducing information, and malfunction in recording and reproducing information is decreased.

Title: Production of highly clean steel
Inventor: HIRAOKA TERUYOSHI
IPC: C21C7/06
Filed: 1982-10-18
Abstract: PURPOSE:To clean the molten steel in a low solAl and low C region at a high degree in the secondary refining of the molten steel tapped from a steel making furnace to a ladle by adding a flux for accelerating the coalscence and floating of inclusions together with a required amt. of a deoxidizing agent to the molten steel under tapping. CONSTITUTION:A deoxidizing agent such as Al or Si is added to the molten steel under tapping to form the resulted product of deoxidation in an early time and to assure the time for the coalscence and floating till casting. The temp. drop during the tapping is decreased to lower the tapping temp. and to decrease the intrusion of the source for inclusions occuring in the erosion of refractories. Otherwise, the time for stirring in the secondary refining is extended as much as the temp. is decreased. The above-mentioned addition of the flux contributes to the fine dispersion of a low melting slag making agent into the molten steel by the stirring energy during tapping and the coalscence and floating of the resulted products of deoxidation such as Al2O3, SiO2 or the like to each other; at the same time, the adsorbed and absorbed layer of the floated inclusions is formed on the surface of the molten steel. A slag reducing agent for reforming oxidative slag may be added to the molten steel in the stage of tapping.

IPC: B60K23/08
Filed: 1981-11-13
Abstract: PURPOSE:To prevent the mistaken use of a car at the time of two-wheel driving by making it possible to use an emergency low (EL) speed change stage only at the time of four-wheel driving in a speed change gear wherein the gear mechanism of the EL speed change stage having a further larger gear ratio than the first speed has been assembled into the speed change gear. CONSTITUTION:When a knob 38 is shifted to a two-wheel driving position, the atmospheric pressure is supplied into the control chamber 29 of a selector valve 27 by a selector valve 40, and a shifter rail 25 is moved to the left by a spring 30. Accordingly, an intake negative pressure is introduced into the chamber 37b of an actuator 35 via negative pressure passage 44, 45, and a shift rail 33 is moved to the left via a diaphragm 36. Consequently, a selector device 23 becomes a two-wheel driving state while separating a transfer gear 22 from a transfer shaft 21. When the shifter rail 25 is moved, keeping this state, to the right, and an EL speed change stage (not illustrated) is shifted via a shift fork 26, intake negative pressure is then supplied to the chamber 37a side by a selector valve 27, allowing a car to be automatically changed to a four-wheel driving state.
