Title: Seal device of stack for discharging inflammable gas
Inventor: KITANO AKIHIKO
IPC: F17C13/12
Filed: 1987-02-27
Abstract: PURPOSE:To obtain a seal device sharply saving the cost of the nitrogen gas by providing a liquid discharging mechanism and a liquid feeding mechanism detecting the density of the inflammable gas and opening or closing the feed valve of the nitrogen gas and feeding or discharging the liquid in a liquid sealing mechanism. CONSTITUTION:The nitrogen gas is filled in a stack cylinder body 1. When the inflammable gas flows in, the inner pressure is increased, the liquid of a liquid storage section 4 generates the liquid level difference, which is sensed by a level detector 13. When the level of the liquid level B rises, a liquid discharge valve 11 is opened, and the liquid is discharged from the liquid storage section 4. At the same time, a nitrogen gas feed valve 10 is opened. When the density of the inflammable gas is lowered, it is detected by a gas detector 9, the nitrogen gas feed valve 10 is closed, and simultaneously a liquid feed valve 12 is opened. When the liquid pressure is detected to be the preset value by the level detector 13, a liquid feed valve 12 is closed.

Title: Shield cover
Inventor: OOHASHI NORIAKI
IPC: B60K11/04
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To positively draw out hot-air in an engine room and to extensively reduce noise out of a car. SOLUTION: A shield cover 7 to cover a lower side of an engine room 4 of a vehicle is formed in a flat duct shape to release a ventilating channel 8 toward a travelling direction of the vehicle, and an opening part 12 to communicate the ventilating channel 8 and the engine room 4 to each other is provided on its upper surface. At the time when the vehicle travels, travelling air is rectified and flows in the ventilating channel 8 of the shield cover 7, the side of the ventilating channel 8 becomes relatively low pressure against the side of the engine room 4 by pressure lowering work caused by a rectified flow of the travelling air, and air in the engine room 4 is sucked from the opening part 12 to the ventilating channel 8 and drawn out.  Additionally, noise in the engine room 4 leaked from the opening part 12 is damped as its propagation to the outside of the vehicle is avoided by a lower part of the shield cover 7.

Abstract: PURPOSE:To accurately measure a test load by providing a member which extends and contracts by being applied with a voltage between a load detection part which detects the load placed on an indenter and the indenter. CONSTITUTION:A loading device 1 increases or decreases the load with the electromagnetic force of an electromagnetic coil 6 with the load current supplied from a load current supply device 16 to the electromagnetic coil 6 to increase, decrease, and stop optionally the load placed on a sample 14 mounted on a sample base 13 through the indenter 5. The piezoelectric extension member 11 is interposed between the indenter 5 and a balance 8 which transmits the test load to the indenter 5 and when the load is placed to press the intender 5 against the sample, the voltage is applied from a piezoelectric application device 18 to the piezoelectric member 11 to increase the length of the piezoelectric member. At this time, the load current is so supplied that the balance 2 is held in a balanced state, and then the indenter 5 is lowered by the extension quantity of the piezoelectric member 11. Thus, the indenter 5 is intruded into the sample 14. At this time, the load current which is supplied is measured to measure the placed load.

Title: Quantum well type semiconductor laser
Inventor: IMANAKA KOICHI
IPC: H01S3/06
Filed: 1987-02-27
Abstract: PURPOSE:To obtain a quantum well type semiconductor laser, in which laser oscillation in short wavelengths is obtained, without narrowing the width of a quantum well, by providing a reflecting film having wavelength selectivity, in which two kinds of dielectric layers, which have a thickness of 1/4 the light emitting wavelength in transition between the desired high-order levels of the quantum wells and have different refractive indexes, are alternately laminated at the rear end surface of the semiconductor layer in four layers. CONSTITUTION:On a substrate 1, a buffer layer 2, a lower clad layer 3, an active layer in a quantum well structure, an upper clad layer 5 and a cap layer 6 are sequentially formed. Electrodes are formed on the lower surface of the substrate 1 and the upper surface of the cap layer 6. A reflecting film 7 having wavelength selectivity is formed at the rear end surface of a Fabry-Perot type quantum well semiconductor laser. The reflecting film 7 is formed by laminating dielectric layers 7a and 7b, whose refractive indexes are na and nb (nanot equal to nb), respectively, alternatly in four layers, so that the thickness of each layer is 1/4 the wavelength of the light within a crystal. Therefore, the reflectivity of the reflecting film 7 is large only for the light emitting wavelength in transition between the selected high-order levels. Thus, the high-order, i.e., short-wavelength laser oscillation is obtained.

Filed: 1991-02-15
Abstract: PURPOSE:To lessen dead spaces in area when housing units are set in parallel by narrowing each width of columns which are mutually adjacent, in dimension in the direction where they are set in parallel. CONSTITUTION:As for the columns 4 and 5 of a housing unit 1A, the columns 3 and 6 of a housing unit 1B, the columns 3 and 6 of a housing unit 1C and the columns 4 and 5 of a housing unit 1D, only a dimensional width in the direction of each side of the housing units is made to be W/2 which is narrower in width than the other columns. And as for four columns 6, 5, 4 and 3 where the respective housing units 1A through 1D get together, each of them is formed into a square column each side of which is W/2 in width. When living room units 11, 12, 13 and 14 are made up with the four housing units 1A through 1D adjacently set in parallel, the dimensional width beta of a dead space formed can thereby be eliminated by W which is the dimensional width of one column, as compared with a former width alpha.

Title: Forming of optical element
Inventor: YAMAMOTO KIYOSHI
IPC: G02B5/18
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To secure a desired shape accuracy and enable the forming in the shortest time by specifying a glass material and the temperature range of a forming mold in a method for pressing the glass material in the forming mold and forming an optical element. SOLUTION: A glass material 6 is heated at a specified temperature, then sucked with a suction hand 5 and charged into a forming mold kept at a prescribed temperature. After evacuating the hand 5, a top force 1 is directly lowered to carry out the pressing. At that time, the glass material 6 kept at above ambient temperature and below a temperature (described as T0 ) at which the glass viscosity corresponds to 10<13> dPas is pressed with the forming mold kept at a temperature within the range (T1 to T0 ) at which the glass viscosity corresponds to 10<8> to 10<13> dPas. The glass is softened at a temperature above T0 and the thermal expansion coefficient is rapidly increased.  Thereby, the difference in expansion coefficient from the mold member is increased to deteriorate the shape accuracy of an optical element due to a shrink mark at the time of cooling and melt sticking of the mold member with the glass material 6 frequently occurs. When the mold temperature is below the temperature T0 , the shape accuracy is deteriorated to readily cause the melt sticking above the temperature T1 .
