Title: Control rod driving mechanism
Inventor: MATSUMOTO FUJIO
IPC: G21C7/14
Filed: 1990-07-23
Abstract: PURPOSE:To reduce the diameter of a housing and to enhance heat removing properties by suspending a combination of a ball nut and a ball screw from a drive motor through an electromagnetic clutch. CONSTITUTION:At a normal time, an electromagnetic clutch 31 is excited to transmit the rotation of a drive motor 10 to a ball screw 32 and, when the screw 32 is rotated, the ball nut 34 threaded with the screw 32 and a guide case 33 moves up and down along the screw 32. The extension pipe 21 suspended from the lower end of the case 33 slides through a seal mechanism 37 while holding its airtightness and the control rod 24 suspended from the extension pipe 21 is inserted in and detached from a core to adjust the output of the core. When the clutch 31 is cut off at the time of the emergency shutdown of a nuclear reactor, the case 33 receives the pressing force of the compressed gas sent from a gas storage tank 19 and falls along a guide key 35 by its own wt. and the wt. of the lower suspended matters applied thereto. By this structure, the electromagnetic suspending the extension pipe through a latch mechanism becomes unnecessary and, therefore, the diameter of a housing 8 is reduced and heat removing properties can be enhanced.

Title: Wavelength stabilizer for semiconductor laser
Inventor: KAEDE KAZUHISA
IPC: H01S5/068
Filed: 1984-09-14
Abstract: PURPOSE:To contrive to inhibit the chirping of oscillation frequency by a method wherein the fluctuation of optical resonator length generated by varying the number of carrier electrons injected to the active layer through the first electrode is compensated by the increase the decrease in number of carrier electrons injected through the second electrode. CONSTITUTION:When current is impressed on the active layer 201 through an electrode 213 and a common electrode 212, laser is oscillated by the resonator formed out of a diffractive grating 204 and a cleavage surface 219. At this time, impressing modulated signals on the electrode 213 in order to modulate the strength of laser oscillated light varies the density of the carrier electrons in the active layer 201 at the current-injected region immediately under the electrode 213; therefore, the variation in refractive index due to the changes of dispersion curve for flexing rates which relate with the plasma effect of free electrons and the interband transition of electrons occurs, and the optical length of the region of the active layer 201 immediately under the electrode 213 changes. However, since the control current which causes the variation in refractive index enough to compensate the variation in optical resonator length generated by modulated signals is injected to the second electrode 214, the resonator length is kept constant as a whole.

Title: Axial flow type laser oscillator
Inventor: NAWA AKIYOSHI
IPC: H01S3/041
Filed: 1986-08-19
Abstract: PURPOSE:To keep positional relationship between resonators at an initial state even if thermal expansion is present and to prevent decrease in functions of a laser oscillator, by forming a hollow part in a supporting shaft for the resonators, using the hollow part as a feeding path of laser gas, forming hollow parts in the base table of the oscillator, and using the hollow parts as paths for cooling water. CONSTITUTION:When laser gas is supplied through a feeding pipe 4, the gas is split in a block 2a. One stream reaches an exhaust pipe 5 through a discharge electrode 3 directly and a block 2c. The other stream reaches the exhaust tube 5 through the hollow part of a supporting shaft 10, a block 2b, another discharge electrode 3 and the block 2c. Thus the gas is exhausted. During this period, constituent parts are heated by the discharge actions of the discharge electrodes 3 and 3. Since cooling water passes through hollow parts 12 of a base table 1, the increase in temperature of each member is suppressed. Therefore, the effect of thermal expansion can be decreased. Thus, alignment of a total reflecting mirror 8 and a partial reflecting mirror 9 with respect to the discharge electrodes 3 and 3 can be kept at the initial starting state of the oscillator, and the stable operation can be maintained.

Abstract: PURPOSE:To manufacture a thin-film phosphor having high luminous efficiency with improved reproducibility, by growing a thin film of highly crystalline zinc oxide on a substrate and then conducting luminescence treatment by heat treatment in a predetermined atmosphere selected on the basis of the zinc to oxygen ratio. CONSTITUTION:A conductive layer 2 is vacuum-deposited on a substrate glass 1. A thin film 3 of highly crystalline zinc oxide is grown on the conductive layer. With respect to a thin zinc oxide film 3 having a zinc to oxygen ratio close to the stoichiometrical compsn. rather than to the optimum compsn. ratio for a phosphor, heat treatment is conducted in a zinc atmosphere or a reducing atmosphere so that the zinc to oxygen ratio becomes optimum for a phosphor. On the other hand, with respect to a thin zinc oxide film 3 having a zinc to oxygen ratio which is zinc-excess as compared with the optimum compsn. ratio for a phosphor, heat treatment is conducted in an oxidizing atmosphere so that the zinc to oxygen ratio becomes optimum for a phosphor. Thus, luminescence treatment is conducted to obtain a thin film phosphor of zinc oxide.

CONSTITUTION:A injection angle theta of a fuel injection nozzle 11 is set largely enough such that atomized fuel injected through an atomizing passage 14 into a vortex chamber 6 is in contact to an outer peripheral surface of a rectificaton bar 15 in its side portion of a centeral side of the vortex chamber 6, and in contact to an end portion of a glow plug 12 in its side portion of an outer peripheral part of the vortex chamber 6. Since the atomized fuel is so injected that the side portion thereof on the central side of the vortex chamber is substantially in contact to the outer peripheral surface of the rectification bar 15, a part of the atomized fuel is certainly supplied to an air retention area Z which is most ignitable. The rectification bar 15 thermally accumulated at a high temperature is arranged in the vicinity thereof, so that the fuel supplied to the area Z ignites with certainty and speed. The ignitability of the fuel is thus improved.

Title: Magnetic disk
Inventor: SHINOHARA HIDEKI
IPC: G11B5/62
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic disk substrate for a hard disk capable of easily attaining a higher speed of rotation and lessened electric power consumption by constituting the magnetic disk substrate of a magnesium based alloy contg. inevitable impurities and magnesium in excess of a specific weight per cent. SOLUTION: The torque and energy necessary for rotating an object are proportional to the moment of inertia of the object and the moment of inertia is proportional to the sp. gr. of the material in the case of a disk shape of the same size. The magnesium based alloy contg. >=50 wt.% magnesium is used for the hard disk. On the other hand, the countermeasure by the strength reinforcing plate in the central part for the damage of the hard disk by a centrifugal stress may be made less than in the case an aluminum based alloy is used. As a result, the driving with a lower-output motor is made possible and the size of the hard disk device may be reduced and the electric power consumption thereof is reduced. Further, the reduction of the centrifugal stresses is possible and, therefore, the higher-speed rotation is made possible.
