Title: Nitrogen oxides cleaning catalyst
Inventor: KIZAKI YOSHIMI
IPC: B01J23/89
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To efficiently remove nitrogen oxides even with a small quantity of a noble metal element and a hydrocarbon(HC) by constantly keeping the surface of a catalyst oxygen-free and using the noble metal element to reduce only oxygen generated by decomposing and dissociating nitrogen oxides. SOLUTION: The catalyst is constituted so as to have a double layer structure of a 1st catalyst layer 1, which uses a material having large oxygen occluding rate and on the surface of which the noble metal 3 is carried, and a 2nd catalyst layer formed to almost or fully cover the surface of the 1st catalyst layer except the surface, on which the noble metal is carried. As a result, the action of the noble metal, is drawn at most even in a small quantity and nitrogen oxides are efficiently removed even in an excessive oxygen atmosphere.

Abstract: PURPOSE:To perform positional detection with good accuracy without receiving effect due to the adjacent pitch error of a scale, by outputting a position detecting signal when a second detector detected the signal with respect to the same part where the signal from the scale was detected by a preceding first detector. CONSTITUTION:In detecting the signal at every one pitch from a scale 2 arranged to an article to be measured and relatively moving to the direction shown by an arrow by two sets of sensors CD, AB arranged in preceding detection order, a position detecting signal is outputted at the time t1 when the operation output of the sensor AB comes to zero at the n1-part of the scale 2 and the value alpha of the operation output of the sensor CD at the n2-part of the scale 2 is read at the time t1 and a position detecting signal is outputted when the operation output at the time of the detection of the n2-part at time t2 by the sensor AB after the movement of the scale 2 comes to alpha. By repeatedly performing this processing, an equal pitch signal is outputted on the basis of the fixed distance between the sensors AB, CD.

Title: Variable wavelength filter module
Inventor: TSUDA HIROYUKI
IPC: G02F1/13
Filed: 1990-03-23
Abstract: PURPOSE:To allow sweeping over a wide wavelength range by providing a circuit which controls a transmission wavelength and an electronic circuit which maintains a variable wavelength filter at a specified temp. in the variable wavelength filter. CONSTITUTION:Wavelength multiplexed optical signals are guided to a polarization maintaining optical fiber PF1. This light is converted to collimated beams of light of about 100 mum diameter by a lens L1 and is made incident on the variable wavelength filter VF1. Only the arbitrary one wave among the multiplex light signals is transmitted through the VF1. The selected light is coupled by a lens L2 to a polarization maintaining optical fiber PF2 and is outputted therefrom. The transmitted wavelength of the variable wavelength filter VF1 is controlled by the voltage impressed from an electronic circuit EC2 for controlling the variable wavelength filter to a transparent electrode layer TEL. Since the transmitted wavelength of the variable wavelength filter VF1 depends on the ambient temp., an electronic cooler CL is mounted and the specified temp. is maintained by the electronic circuit EC2 for controlling the electronic cooler. The sweeping of the wide wavelength range with the low voltage is executed in this way.
