IPC: G01J1/02
Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To measure stably without scattering in accuracy by coupling a cylindrical body passing a laser light therethrough to a front face of a laser output detector, and setting a scattering body scattering the laser light at a leading end part of the cylindrical part and a partial transmitting body at a terminal end part of the cylindrical body. SOLUTION: A cylindrical body 2 passing a laser light from a laser to be measured is screwed and coupled to a front face of a laser output detector 1. A scattering body 3 scattering and passing the laser light is set at a leading end part of the cylindrical part 2, and a partial transmitting body 4 is set at a terminal end part. The laser light from the laser to be measured which is set immediately before the cylindrical body 2 is scattered first by the scattering body 3, passes the cylindrical body 2, is attenuated in amount by the partial transmitting body 4 and reaches a sensor 9. The sensor 9 converts the light to an analog detection signal and a built-in circuit 10 processes the signal. A connector 11 outputs a laser output detection signal.  Since the leading end of the cylindrical body 2 is opened wide, the laser to be measured can be inserted into the cylindrical body 2 easily. Moreover, since the laser light is scattered by the scattering body 3, the light can be uniformed and surely sent to the sensor 9 even if it is inferiorly directional.

Title: Air bleed method of hydraulic damping device
Inventor: IGARASHI SUNAO
IPC: B60T17/00
Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To improve the responsiveness of a hydraulic damping device and prevent a noise. SOLUTION: By keeping a stationary stable state for a prescribed time after removing the air in a brake device 1 at a normal temperature from an air removing valve 14 provided on a wheel cylinder 12, the residual air with a particulate shape melted in a brake liquid is risen naturally and educed as a bubble to the base of the air removing port 12b. Thereafter, when the temperature around the air removing valve 14 is risen to 50 deg.C or more by a heater, the temperature of the bubble educed to the base is also risen and expanded. When the air removing valve 14 is loosened again under this state, the bubble with a expansion pressure is discharged from the air removing valve 14 naturally.  Therefore, the responsiveness is improved and the lining 10 of a brake shoe 9 is separated from the inner periphery surface of a drum 7 surely at the releasing time of a liquid pressure and the generation of a noise by the draging phenomenon of a friction means 3 is prevented. Further, a running stability is improved due to no ununiform draging of each wheel.

Title: Air conditioner
Inventor: AKATSUKA HIROSHI
IPC: F24F5/00
Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To increase the condensing capacity of an outdoor heat exchanger in cooling operation and increase the evaporating capacity of the outdoor heat exchanger in heating operation by connecting two or more outdoor heat exchangers in series. SOLUTION: In cooling operation, refrigerant and cooling water enter an outdoor heat exchanger 11b from an outdoor heat exchanger 11a. In the heat exchanger 11a, both of the cooling water and the refrigerant are cooled by the outside air since a cooling water pipe has a large proportion of a heat transfer area, and both the cooling water and the refrigerant have high temperatures and a small temperature difference between them. In the heat exchanger 11b where the cooling water tube has a small proportion of heat transfer area, heat of the cooling water is hardly transferred to the refrigerant, and further, the temperature of the cooling water is low to lower the temperature of the refrigerant. Therefore, the temperature of the refrigerant is rendered low to increase the condensing capacities of the heat exchangers 11a, 11b.  In heating operation, the refrigerant flows from the heat exchanger 11b to the heat exchanger 11a. The refrigerant which has absorbed outdoor heat and the cooling water prior to discharging heat to the outside air flow into the heat exchanger 11a. Accordingly, the cooling water has a high temperature and thus the evaporating capacities of the heat exchangers 11a, 11b are increased.

Title: Planer waveguide type filter
Inventor: ITO MASUMI
IPC: G02B6/12
Filed: 1996-08-16
Abstract: PROBLEM TO BE SOLVED: To provide a planer waveguide type filter having excellent light- intercepting characteristics. SOLUTION: In a planer waveguide type filter in which a core 3 serving as a waveguide for light is formed on a substrate 2, a clad 4 is formed on the core 3, and a grating 5 for reflecting only the light having the particular wavelength is provided in the core 3, a light-releasing layer 6 having higher index of refraction than that of the clad 4 is provided on the clad 4. Thus, light falling from the core 3 into the clad 4 is not reflected from the boundary surface of the clad 4 to be entered into the light-releasing layer 6 and then released to the outside. Consequently, since the light does not fall into the core 3 again after it makes a circuit round the grating 5, excellent light-intercepting characteristics can be obtained.
