Title: Inspection of porous protective layer of oxygen sensor
Inventor: SHIMURA TOMOAKI
IPC: G01N27/26
Filed: 1989-02-28
Abstract: PURPOSE:To enable direct and exact inspection without breaking the sensor by impressing a voltage between an outer electrode and an inner electrode while the atmosphere on the outer side is maintained in a prescribed oxygen excess state and measuring the limit current value, then passing judgment. CONSTITUTION:The outer electrode 2 formed on the outside surface of a solid electrolyte 1 such as oxygen sensor ZrO2 and the inner electrode 3 formed on the inside surface are connected to a DC power supply 4 and the DC voltage as much as the voltage drop by resistance polarization plus <=2V is impressed between the two electrodes 2 and 3. A heater 5 is inserted into the oxygen sensor and the sensor is previously heated to about 600-800 deg.C at this time. The outer electrode 2 is placed in the atmosphere in which the oxygen concn. is constant and which is mixed with a gas such as steam contg. oxygen atoms. The O2 of the 3 phase boundary where the outer electrode 2 comes into contact with ZrO2 magnetism is reduced and moved and is released into the inner electrode 3 when the DC voltage is impressed to the electrodes.

Title: Drum type scanner
Inventor: SATOU TSUTOMU
IPC: G03B27/00
Filed: 1980-04-14
Abstract: PURPOSE:To accurately oppose subscanning to main scanning by apportioning the pulses of the remainder of division to any of the subscanning driving pulses when the number of rotating pulses of a main scanning drum is indivisible by the number  of pulses of the subscanning. CONSTITUTION:A rotary drum 1 for recording is rotatably driven by a main scanning motor 3 by way of a joint 2. The carriage 5 and head 9 on guide bars 4a, 4b are driven in parallel with a drum shaft 1a by a subscanning motor 7 by way of a wire 6. The main scanning rotating pulses of the drum 1 are obtained by a pulse encoder 10 mounted to the drum shaft 1a, and when the number of these pulses is indivisible by the number of pulses for subscanning driving, the number of the pulses of the remainder is so frequency-divided as to be apportioned to the prescribed number of pulses of the subscanning driving. Thereby, the main scanning and the subscanning are synchronized.

Title: Method for separating and recovering rhodium
Inventor: NISHIMURA YAMAJI
IPC: C22B11/00
Filed: 1990-02-28
Abstract: PURPOSE:To nearly perfectly separate and recover Rh by adding bivalent tin halide to an Rh-containing hydrochloric acid solution and using dialkylsulfide to which higher alcohol is added as an extracting agent. CONSTITUTION:The hydrochloric acid concentration of a hydrochloric acid solution of Rh containing base metals is regulated to 0.5-12N, and bivalent tin halide is added by the amount 1.5-12 times Rh by mole ratio. subsequently, Rh is extracted by using an organic solvent in which dialkylsulfide is used as extracting agent and higher alcohol, such as diethylhexanol, is incorporated as modifier. The organic solvent phase after Rh extraction is cleaned with 0.5-1N dilute hydrochloric acid to elute tin. Then, Rh is precipitated in the form of sulfide, e.g. by blowing hydrogen sulfide into the organic solvent phase after tin elution. The precipitated Rh sulfide is separated by filtration and heated and recovered in the form of metallic Rh. By this method, a recovery rate of >=99% can be attained.

Title: Low-pressure treatment device
Inventor: OGAWA KAORU
IPC: H01L21/302
Filed: 1992-03-06
Abstract: PURPOSE:To suppress generation of a fine particle by achieving a wide range of pressure control by providing a plurality of pressure control mechanisms in series between a treatment chamber and a vacuum pump. CONSTITUTION:Pressure of an etching treatment chamber 1 is constantly reduced to a high degree of vacuum by vacuum pumps 5A and 5B and pressure at the time of treatment is controlled by a vacuum control mechanism B (4B). However, when etching is tried to be performed, an opening of a valve of the pressure control mechanism B (4B) is nearly closed completely although it is normally 100% open and generates pressure hunching sometimes since the movement of the valve is large, thus causing pressure control to be unstable. Then, a donut-shaped circular plate is newly provided as a pressure control mechanism A (5A) so that it can be mounted and removed freely, thus reducing an apparent exhaust capacity, reducing the opening of the pressure control mechanism B (4B) to approximately 50% and reducing the movement of the valve, reducing the number of fine particles, and stabilizing pressure control.
