Title: Detecting method for concentration of oxygen
Inventor: NAKAJIYOU YOSHIKI
IPC: G01N27/49
Filed: 1980-09-05
Abstract: PURPOSE:To enable detection of O2 concentration in a wide range with excellent accuracy even at a low temperature by putting a proton-containing medium in a porous ceramic vessel and by providing in the medium an electrode to which a compound, such as metallized prophyrin, having the function of an electron transfer catalyst is attached and a reference electrode. CONSTITUTION:The functional electrode 5 to which a catalyst 4 prepared by metallizing tetraaminophenyl porphyrin or the like with FeCl2, CoCl2 or the like and having the function of an electron transfer catalyst is attached is made. The medium 2 containing proton such as polyacrylic amide is put in the porous ceramic vessel 1, while the electrode 5 and the reference electrode 3 are put in the medium 2. This ceramic vessel 1 is covered with a metallic cover 17 having a plurality of holes 20 and fixed to a housing 11. Next, the housing 11 is fixed to a conduit 18 for exhaust gas (an arrow 19 indicates the flow of gas) with a thread groove part 14. O2 dispersed in the medium 2 is reduced with contact by impressing voltage on the electrode 5 and the current generated in the process of reducing reaction is measured. The current is generated as a function of the density of O2. Thus the device is applied to an air-fuel-ratio sensor and the like having high durability even against high temperature and high accuracy.

Title: Oscillating circuit
Inventor: KOIKE HIROYUKI
IPC: H03K3/354
Filed: 1992-05-15
Abstract: PURPOSE:To keep an oscillating frequency constant by applying a prescribed voltage to transistors(TRs) of each inverter block of a ring oscillator from 1st and 2nd constant voltage generating circuits accordingly. CONSTITUTION:When a power supply voltage Vcc changes at a constant voltage circuit 2a and its node N1 gets a higher level than a prescribed potential, a differential amplifier circuit DA1 is operated, a potential at an output node N5 is decreased and a gate-source potential of a TRQ2 is changed, then a drain-source current of the TRQ2 increases, and a potential at a node N3, that is, a 1st voltage Vr1 increases. When a potential at the node N3 is equal to a potential at the node N1, the output node N5 reaches a prescribed potential. That is, the TRQ2 acts like a constant current circuit 2a to set a gate level of 3rd TRs Q13, Q23, Q33 of inverter blocks 11a-11c to be a prescribed potential at all times. A constant voltage circuit 2b is operated similarly.

Title: Build-up welding method
Inventor: TAKASE IWAO
IPC: B23K33/00
Filed: 1978-10-06
Abstract: PURPOSE: To obtain welded structure of high reliability not causing hydrogen attack, by build up welding the surface of deposited metal of welded joint of steel structure used under the environment of high-temperature, high-pressure hydrogen, in the specified position by using pure iron filler metal.  
     CONSTITUTION: Weld zones of base metal 1, especially weld metal 5 in the final welding layer and coarse crystal heat affected zone 2 are likely to cause high-temperature, high-pressure hydrogen brittleness. In order to prevent this, build-up welding 4 is performed so that the weld end part may be positioned 1 to 5mm inside of the weld end part. As a result, the coarse grain region of the coarse crystal heat affected zone 2 and weld metal 5 is changed to fine grains by the heat cycle of build-up welding, and the resistance to hydrogen is improved by the tempering effect. If 1mm or less, new coarse crystal heat affected zone is formed; if 5mm or more, the fine granulating effect does not appear. The build-up weld should consist of pure iron having a high resistance to hydrogen, or one or two or more kinds of carbide forming elements being stable against hydrogen attack, Cr 3% or less, Mo 1% or less, and Ti 0.3% or less, and the remainder of iron.

IPC: B01D3/32
Filed: 1977-10-13
Abstract: PURPOSE: To decrease nonvolatile impurities contained in product liq. without increase of heat quantity to be added to a reboiler for evaporation, by concentrating the circulating liq. through a thermosyphon reboiler and a gas/liq. separator installed at the outlet of the reboiler, and by drawing off a very small amount of the conc. liq.  
     CONSTITUTION: A liq. 1 contg. nonvolatile impurities is fed to a evaporating column 2, and the top vapor 3 is divided into product liq. 6 and reflux liq. 7. Bottom liq. 10 of the evaporating column 2, in which nonvolatile impurities remain, is drawn off through a line 8 and the bottom liq. 10 in an amount equal to that evaporated at the reboiler 9 is fed to the reboiler 9. Then the mixed gas/liq. fluid flowing out of the reboiler 9 is charged 14 to a gas/liq. separator 11, the vapor being returned to the column 2, and the liq. to the reboiler 9, a very small amount 16 of which is drawn off. It is pref. to increase the concn. of nonvolatile impurities of circulating liq. between the separator 11 and the reboiler 9 nearly to saturation. Thus the amount drawn off the line 16 is made as small as possible, consequently, product loss and heat quantity taken away by drawn-off liq. is made as small as possible

IPC: G03G15/00
Filed: 1980-09-08
Abstract: PURPOSE:To prevent the shortage of copying paper by inputting a pulse signal to a display part by the output signal of a comparator which compares the set number of sheets of paper with the counted number of sheets of paper, and by informing that the display is count number by flashing the display part with copying operation is interrupted. CONSTITUTION:The number of sheets of copying paper, when inputted with a set button 1, is displayed on a display part 2 through a switch 11 and pushing a start button 5 starts copying operation. Then, the count value of a counter 15 is compared by a comparator 16 with the number of sheets of copying paper stored in a storage device 10. If abnormality detector 19 detects a paper jam during operation or if an interruption switch 7 is pushed, the output of a control part 13 interrupts the copying operation and a pulse signal is inputted to an AND gate 18. Since the count value of the counter 15 is less than the stored vaue of the storage device 10, the switch 11 connects the output side of the gate 18 to a display part 2, which flashes to indicate that the displayed number of sheets is the counted number of sheets.
