Title: Treatment of polluted air
Inventor: KAGITANI TSUTOMU
IPC: B01D53/62
Filed: 1986-03-19
Abstract: PURPOSE:To carry out oxidation treatment of carbon monoxide in polluted air easily, effectively and economically by irradiating an oxygen-containing gas containing carbon monoxide with ultraviolet rays in the presence or not in the presence of catalyst and in the presence of ozone without particularly heating up. CONSTITUTION:Gas containing oxygen such as polluted air containing CO, combustion off-gas and the like is put into a reaction container in which a high-pressure mercury vapor lamp or the like is built-in, ozone being added, and the high-pressure mercury lamp is switched to allow on ultraviolet rays to irradiate the gas. With ultraviolet rays, electromagnetic wave capable of generating ozone can irradiate the gas. CO is converted into harmless CO2. Further, treatment efficiency of CO can be increased by contacting with oxygen- containing gas containing CO such as a method of applying catalyst comprising silver, platinum and the like supported on titanium oxide over the inner wall or reaction container and the like.

Title: Protective relay device
Inventor: NIINUMA SHIGERU
IPC: H02H3/30
Filed: 1990-03-14
Abstract: PURPOSE:To confirm and test a 'no' voltage without removing a voltage relay by using a closing command detecting voltage relay circuit for transmitting a pause release command to an opponent end only when a breaker or a disconnector of own end is 'opened' and a breaker and both a disconnector of the opponent end are 'closed'. CONSTITUTION:A contact of 52BZ to be excited by the AND condition of 'opening' of own end CB and 'closing' of an opponent end CB is connected in series with a voltage relay 52CZ having a high resistance. Thus, a microcurrent flows a closing coil CC only when the own end CB is 'opened' and the opponent end CB is 'closed', and no microcurrent flows the coil CC when the sub-CB are 'closed' or the sub-CB are 'opened' at all the terminals. Since the 52BZ is limited to be operated only if the two terminals of the opponent are operating and the own end is paused, 'no' voltage by measuring the voltage of the closing circuit to be executed can be confirmed and tested without fail at the time of starting the operation of a device in most cases.

Filed: 1983-04-12
Abstract: PURPOSE:To detect corectly an indicator area and to simplify a circuit constitution by setting the basic frequency in terms of the record information of the indicator area to a specific extremely low value compared with the basic frequency of a data area. CONSTITUTION:The record information is recorded with a low frequency so that the basic frequency of the record information of an indicator area (a) is set at 1/2n frequency compared with the basic frequencies of a data area (c) and an address area (b). Thus the interference is reduced to the information of the area (a) itself although some inter-code interference is produced to the signal read out of a recording medium 1. In such a way, the detection of the area (a) is assured. In addition, it is possible to use a PLL circuit or a demodulating circuit in common each other just by a frequency dividing circuit by using the medium 1.

Title: Heat treatment for sleeve roll
Inventor: UEHATA RYOICHI
IPC: C21D9/38
Filed: 1987-03-20
Abstract: PURPOSE:To prevent breakage accident and also to increase quenching rate, by holding a diffusion-annealed sleeve roll at a temp. in a specific range until respective temps. in the inner and outer layers are equalized and then subjecting the above to rapid heating to apply temp.-rise to the outer layer alone so as to carry out hardening treatment. CONSTITUTION:After a sleeve roll stock for shape rolling whose outer-shell layer is composed of adamite is diffusion-annealed quench-and-temper treatment is applied. In the above heat treatment, the above sleeve roll stock after diffusion annealing is held at a temp. between 500 and 750 deg.C until respective temps. in the inner and outer layers are equalized. Subsequently, rapid cooling is applied to subject only the outer layer of the roll to temp.-rise up to 830-950 deg.C. Then, the roll stock is taken out of a furnace and cooled to undergo hardening treatment. By this method, the difference in temp. between the inner and outer layers is reduced in the hardening stage so as to reduce stress. As a result, the roll stock causes no occurrence of breakage accident in the hardening and subsequent annealing stages and is also increased in quenching rate, and high hardness can be provided by means of heat treatment alone.

Abstract: PROBLEM TO BE SOLVED: To uniformly perform the initialization of a phase transition type optical disk. SOLUTION: This initialization device irradiates the beam spot converged in an elliptic shape with an objective lens 17 on an optical disk 7 and the reflected light from the optical disk 7 is directed toward a focusing servo mechanism 18 by a beam splitter 14. At this time, an abnormal oscillation is generated by the return light to a laser device 12 and a recording layer is inhomogeneously crystallized. In order to resolve this, an initialization is performed by arranging the objectivelens 17 whose numerical aperture is 0.55 so that a beam waist departs from the position of the recording layer of the optical disk 7 by 2μm or more. Moreover, the initialization is performed by arranging the objective lens 17 whose numerical aperture is not larger than 0.50 so that the beam waist becomes the position of the recording layer of the optical disk 7.

Title: Preventing method for oxidation of weld zone in welded can body and device
Inventor: TAKAHASHI YUUZOU
IPC: B23K11/08
Filed: 1979-05-26
Abstract: PURPOSE: To perfectly prevent the oxidation of weld zone by charging the weld zone and its periphery of the can body formed by superposing and welding both end edges of a metal blank into an inert gas region right after the welding followed by cooling.  
     CONSTITUTION: A metal blank 1 is formed to a circular shape by a guide rail 2 and both end edges are superposed and the two superposed end edges are welded by a pair of upper and lower welding rolls 3, 4. Three or more rows of a plurality of gas injection hole groups 9W11 are disposed to the curved face 8 in proximity to the inside surface of the passing can body, from the place near the can body welding completion position to the transfer out direction. The hole group 9 opposes to the weld zone and spouts inert gas to the inside surface of the weld zone to continuously shutt off the weld zone from air thereby lowering the temperature of the can body until it ends passing. The hole groups 10, 11 on both sides isolate the spacing part between the inside faces of the can body from ambient air by the inert gas flows spouted respectively therefrom as well as to prevent the entry of air in the inert gas flow of the hole group 9. The oxidation of the outside surface of the weld zone of the can body is prevented as well by the device similar to that for the inside surface.
