Title: Infrared-ray detecting apparatus
Inventor: TAKADA YUJI
IPC: G01J5/14
Filed: 1989-05-26
Abstract: PURPOSE:To improve S/N and to decrease malfunctions by setting parameters with the values of the capacitance of a pyroelectric element so that the magnitude of an infrared-ray detected signal with respect to the noises outputted from an amplifier becomes the largest value according to the magnitude of the noises generated in the pyroelectric element at the frequency of the infrared- ray detected signal obtained in the pyroelectric element. CONSTITUTION:The parameters of pyroelectric element 1 are determined so that the overall S/N when the pyroelectric element 1 and an amplifier 2 are combined is enhanced based on the relationship between the change in infrared- ray detected signal and noises generated in the pyroelectric element 1 owing to the parameters of the pyroelectric element and noises generated in the amplifier 2. The amplifier 2 amplifies said signal and noises. In this way, the overall S/N when the pyroelectric element 1 and the amplifier 2 are combined can be enhanced, malfunctions of an apparatus can be decreased and sensitivity can be set at a high level.

Title: Grinding method for mirror surface
Inventor: KIMOTO YASUO
IPC: B24B1/00
Filed: 1979-10-17
Abstract: PURPOSE: To obtain a mirror having the uniform surface roughness by shaking a grinding tool at a random cycle and by eliminating the generation of a linear or stripe-shaped crease on the passing boundary of the grinding tool.  
     CONSTITUTION: A rotary tool electrode 2 moves from a starting end A to a final end B, shaking at random and with equal amplitude to a center line 4, while shaking a grinding tool 2' from a subsequent starting end A' to a final end B' at random and with equal amplitude to a central line 1' for grinding. On the occasion, on an intersecting plane 5 formed by two grinding tools 2 and 2', there is little probability that the streaks 7 produced by the grinding motions of the two grinding tools 2 and 2' pass in accord on the same ground surface in view of the random moving trails 6 and 6' formed by the rotational centers of the tools 2 and 2', and these streaks are parallel to each other or intersect each other for the most part. Accordingly, the generation of the linear or stripe-shaped crease on the passing boundary of the grinding tools 2 and 2' is eliminated.

Title: Catalytic burner
Inventor: SHIMADA RYOJI
IPC: F23D14/18
Filed: 1985-06-20
Abstract: PURPOSE:To suppress the slip ratio in the entire combustion catalyst to the minimum by providing a second combustion catalyst having an oxidizing catalyst carrying ratio which is higher than that of a first combustion catalyst, on the outer peripheral portion of the first combustion catalyst having a predetermined oxidizing catalyst carrying ratio. CONSTITUTION:Power is fed to a preheater 6 and generated heat is transmitted to a first combustion catalyst 7, a second combustion catalyst 9 and a heat insulating diffusion material 5. The combustion gas is ejected into a gas chamber 4 and reaches the catalysts 7 and 8 while being heated to a certain degree to start catalytic combustion. Since the catalyst 9 undergoes a cooling effect through the contact with the burner case 1, the fuel slip ratio becomes about 3% in five minutes immediately after the ignition. However, thereafter the reactivity in the catalyst 7 becomes stable and the oxidizing catalyst carrying ratio of the catalyst 9 is larger than that of the catalyst 7. Therefore, it is possible to keep the catalytic probability between the oxidizing catalyst particles and the fuel gas molecules at a high value. Large reaction heat is produced in the catalyst 9 and the unburnt gas discharged from the entire catalytic burner can be suppressed at its slip ratio to 0.1% or less in the normal conditions.
