Patent JP-H01167638-A (JP)
Title: Non-dispersion type optical gas analyzer
Inventor: ROORANDO HIYUU ARUDORITSUJI
IPC: G01N21/61
Filed: 1987-11-30
Abstract: PURPOSE: To obtain an accurate measurement value by providing a radioactive ray source for generating the directional beams of optical energy and a cell in nearly cylindrical shape for housing a sample gas for measuring the concentration in a mixture by analyzing at least one constituent. CONSTITUTION: Light energy is directed so that it passes through a cell 28 where a sample gas mixture has been filled in advance from a radioactive ray source 24 by a reflector 12. Light energy emitted from the cell 28 through a window 32 is applied to the side of a substrate 46 including a masking layer 58 and filters 50-56. In the masking layer 58, light energy can reach only active regions 152-138 of a row of thermocouples 48. The filters 50-56 pass only the selected wavelength of the light energy to the active regions 132-138. Each of thermocouples 68-74 generates a voltage related to the amount of light energy detected by each active region.

Title: Semiconductor wafer
Inventor: MORIZAKI MOTOJI
IPC: B65G49/07
Filed: 1987-11-27
Abstract: PURPOSE:To prevent any damage to the surface of a wafer and destructions of the elements of a semiconductor device, by forming superconductors on a whole or partial part of the surface and rear on the opposite side thereof which is made the semiconductor device. CONSTITUTION:When a wafer 2 is handled during its processing or between processes, a magnetic field applied at the side of the rear 4 causes the wafer 2 to come up to the surface by the repelling force due to Meissner effect and the wafer is handled by causing the rear 4 of its wafer to be sucked by a vacuum pincette and this handling eliminates the need for touching the surface 3 of the wafer 2. While a basket is used for conveying, storing, or cleaning the wafer and then, when magnets 24 are embedded in the partitions 22 and 23 of the basket 21, the repelling force due to Meissner effect acts between a superconductor 1 which is formed at the rear 4 of the wafer and the magnets 24 and allows the wafer 2 to be supported at the intermediate part of the partitions 22 and 23 and further, prevents the surface 3 of this wafer from touching the above partitions 22 and 23. In this way, protection of the surface of the wafer exceedingly reduces destructions because of touching the surfaces of the semiconductor device.

Title: Thread runaway preventing circuit for compact disk device
Inventor: EBARA KAZUNORI
IPC: G11B7/085
Filed: 1991-11-15
Abstract: PURPOSE:To surely prevent a thread runaway when a focus or a tracking servo are ineffective due to a shock or vibration.

Title: Exhaust gas recirculation control valve device
Inventor: ANDO YORIAKI
IPC: F02M25/07
Filed: 1995-11-20
Abstract: PROBLEM TO BE SOLVED: To provide a small-sized EGT valve device with a high responsiveness. SOLUTION: When a current is carried to a solenoid part 13, a solenoid shaft 12 is pushed down to warp a reed valve 6D situated on a lower plate 6C, whereby the air of an atmospheric pressure chamber 9 is carried into a negative pressure chamber 8. Since a diaphragm part 6 is thus moved down by the differential pressure between both the chambers, and an EGR valve 4 is also moved down through a shaft 7, EGR gas quantity is reduced. The positions of the diaphragm part 6 and the EGR valve 4 can be quickly and used according to the change of the current-carrying quantity to the solenoid part 13.  Further, since an air passage 5 is allowed to communicate with a space 17 through a hollow part 16, and the diameter of the EGR valve 4 is substantially equal to that of a piston 15, the force by the pressure difference between the EGR valve and the upper and lower surfaces of the piston is canceled. Therefore, the driving force to the valve 4 can be minimized even when the EGR gas quantity is increased, and the device can be miniaturized.

Title: Vacuum brazing method
Inventor: TEJIMA MASAHIDE
IPC: B23K1/19
Filed: 1987-12-01
Abstract: PURPOSE:To efficiently perform brazing with fine quality in a short time by heating a material to be brazed to which brazing filler metal is fitted while reducing pressure and supplying inert gas and further heating it up to the brazing temperature while increasing the degree of vacuum. CONSTITUTION:The material to be brazed to which the brazing filler metal is fitted is held at the brazing temperature in a vacuum and the vacuum brazing is performed. In this case, heating up to 200+ or -100 deg.C from the ordinary temperature is performed in the air. The evacuation is then started and continuously, while heating it up to the temperature under a solidus line of the brazing filler metal, the pressure is reduced to <=1X10<-2>Torr. As to the temperature under the solidus line of said brazing filler metal, 500+ or -50 deg.C is proper when the material to be brazed is Al or an Al alloy. Afterward, while the evacuation is continued and the pressure is adjusted to 1X10<-2>-2X10Torr, the inert carrier gas such as N2 is introduced continuously. By this method, impurity gas is exhausted sufficiently. Afterward, the introduction of the carrier gas is stopped at the prescribed temperature. While the degree of vacuum being increased, the material to be soldered is heated up to the soldering temperature and soldered.

Title: Refractive/reflection film and its manufacture
Inventor: KAWATE KOICHIRO
IPC: G02B5/08
Filed: 1997-11-04
Abstract: PROBLEM TO BE SOLVED: To provide a refractive/reflection film increasing a light quantity of outgoing light and improving visibility by tilting each other a light refraction surface and a light reflection surface and emitting the light from a light transmissive layer in the direction different from the direction of the light made incident on the light transmissive layer. SOLUTION: Slopes 16 tilting at a prescribed angle (θ) with respect to the surface 13 of the light transmissive layer 12 are formed regularly on the rear surface of the light transmissive layer 12 functioning as the light refraction surface along the fixed direction. When the light is made incident vertically on the surface 13 of the light transmissive layer 12, the light is reflected in the direction different from the incident direction by the light reflection surface 18 tilted for the surface. Then, since the reflected light doesn't become vertical to the surface 13 of the light transmissive layer 12, it is refracted by the surface 13. Thus, the reflected light is deflected in the direction θR=sin<-1> (n sin (2θ)) different from the direction made incident on the surface 13 of the light transmissive layer 12 to be emitted from the refractive/reflection film 10.  Also when the light is made incident obliquely on the surface 13 of the light transmissive layer 12, the same phenomenon occurs.

Abstract: PURPOSE:To suppress the useless energy consumption and to stop a photographing lens on an objective position at the maximum speed under its state by comparing a driving speed with a deceleration curve and decelerating the photographing lens up to a focusing position along the deceleration curve. CONSTITUTION:A CPU 5 calculates the driving distance of the photographing lens 3 based on distance and direction information obtained from a range finding part 4 and the data of a ROM in a lens barrel 1 and converts the obtained distance into encoder pulses.

Every time when the lens 3 is driven and moved by a fixed distance, an encoder 9 generates a pulse and feeds back the moving variable of the lens 3 to the CPU 5. The CPU 5 counts up the pulses generated from the encoder 9, and from a point of time when the lens 3 is reached to a prescribed position, decelerates the lens 3 while comparing the pulse interval of the encoder 9 with the deceleration curve stored in the CPU 5 to stop the lens 3 on the objective position.
