Patent JP-H0366948-A (JP)
Title: Viscosity variable fluid sealed control type vibro-isolating body
Inventor: DOI MITSUHIRO
IPC: F16F13/30
Filed: 1989-07-31
Abstract: PURPOSE:To avoid collision of a movable plate against peripheral members even when there is a vibration of large amplitude from an engine caused by oscillation after cranking in concert with an engine start operation and an engine stop, by applying a control voltage to an electrode plate provided to a rattle element for a specified time after an ignition key is put on or off. CONSTITUTION:Reduction of vibration through thorough usage of an orifice function is performed by applying a control voltage to each of electrode members 44b, 52 in accordance with the number of rotation of an engine and the speed, for example, by locking a movable plate 42 inside a rattle element 40 by way of heightening the viscosity of an electric rheology fluid inside the rattle element 40 at the time of idling of the engine. Subsequently, when an ignition current is fed into the the primary side of an ignition coil at the time of starting of a car, the fluid comes to be in stick state by way of heightening the viscosity of the fluid inside the rattle element 40, the movable plate 42 stored in the rattle element 40 is locked, collision against its peripheral members is avoided and generation of hammering noise is prevented.

Title: Manufacture of semiconductor laser and the same laser
Inventor: TANIGAMI YORIKO
IPC: H01S5/00
Filed: 1994-08-23
Abstract: PURPOSE: To provide a method for manufacturing a semiconductor laser and the laser manufactured by the method in which the deterioration of laser characteristics by energization can be prevented without reducing the current block effect of a current block layer. CONSTITUTION: Since an n-type InP finally embedded layer 10 is provided between a p-type InP third current block layer 7 and an n-type InP contact layer 8, a regrown boundary 9a (boundary between the layer 10 and the layer 8) of the upper part of the embedded layer is not p-n junction but the p-n junction 11 of the upper part of the block layer is not a regrown boundary. Accordingly, the forward voltage of the p-n junction due to energization is not dropped, and hence the deterioration of the laser characteristics due to the drop of the forward voltage can be prevented. Further, from the p-type InP current block layers 5, 7, p-type impurity is not diffused to an n-type InP second current block layer 6, and hence the current block effect of the block layer is not deteriorated.

Title: Continuous annealing furnace for metallic bar
Inventor: FURUICHI KATSUHISA
IPC: C21D9/63
Filed: 1986-08-25
Abstract: PURPOSE:To provide a titled device which anneals plural pieces of metallic bars simultaneously and continuously with high thermal efficiency by disposing hot wind nozzle groups each having approximately the same width as the width of the metallic bar per piece to a pair of plenum chambers of a hot wind injection type continuous annealing furnace in the rows of the same number as the number of plural pieces of the metallic bars passing between said chambers. CONSTITUTION:The width of the hot wind injection nozzle 2 groups to be disposed to the plenum chamber 1 is formed to the same width as the width per piece of the metallic bars 3. The hot wind injected from the nozzle 2 is, therefore, supplied to anneal the bars 3 with the high efficiency. Namely, the high- efficiency furnace is obtd. by changing the arrangement of the nozzle groups even with the furnace to be constructed in the same construction space. While the nozzle width of 350mm is required to pass two pieces of the materials having 100mm width through the furnace having 20m furnace length, the annealing efficiency is improved by 15% by disposing the nozzle groups to 1,200mm width X 2 rows. The same efficiency as the efficiency attained with 300mm width nozzle groups is attained with 17m furnace length. The construction cost is thus reduced.

Title: Optical switch
Inventor: MIKAMI KAZUO
IPC: G02F1/313
Filed: 1982-11-11
Abstract: PURPOSE:To make it possible to use an optical switch also in a high temperature environment by setting up a cooling means close to a demultiplexing point between a main optical waveguide and a demultiplexing optical waveguide to switch a light transmitting direction in accordance with on/off of cooling operation. CONSTITUTION:A high molecular material increases at its refractive index in accordance with the drop of temperature. A cooling body 31 is formed close to the demultiplexing point 30 of the optical waveguide 29 having the main optical waveguide 27 and the demultiplexing optical waveguide 28. When a switch 32 is turned on/off, power supply from a power source 33 to the cooling body 31 is turned on/off and the cooling function of the cooling body 31 is actuated/disabled to switch the light transmitting direction of the optical waveguide 29. Since the temperature close to the demultiplexing point 30 is lower than the peripheral temperature at the time of cooling, the peripheral temperature can be increased up to the upper limit temperature of the material, so that an optical switch allowed to be used in a high temperature environment can be obtained.

Title: Fluid bearing device
Inventor: CHIMA KAZUYOSHI
IPC: G11B5/52
Filed: 1982-11-11
Abstract: PURPOSE:To lengthen the life of a fluid bearing device and to improve the rotation reliability by providing a thrust ring which is minutely deformed by a shock along the thrust and is provided with a thin structure to absorb and moderate such a shock. CONSTITUTION:A thrust ring 9 is provided with a circular groove 21 and with a thin coupling portion 19. The roundness of an appropriate radius of curvature is provided on the forward end of the leg portion 20, so that in spite of minute deformation, the ring is brought into linear contact with a sleeve 10 to reduce frictional resistance to the minimum. When vibration/shock is applied along the thrust, the sleeve 10 is vertically moved to tend to push up the leg portion of the thrust ring 9. The vertical power of the sleeve 10 is, however, absorbed and moderated by spring property of a thin-structure coupling portion of the thrust ring 9. In this case, the leg portion is always brought into linear contact with the sleeve by the roundness expaned outwardly to lessen resistance. Thus, vibration-resisting and shock-resisting properties along the thrust can be improved, thereby to lengthen the life of a video head cylinder.
