Title: Teletext receiver
Inventor: SAKAMOTO MASARU
IPC: H04N7/08
Filed: 1988-04-08
Abstract: PURPOSE:To display a desired teletext program at a display part with a simple operation by providing a memory to discriminate a magazine number, a program number and a page number and store them to a memory and a means to select and display a teletext program accumulated at the memory. CONSTITUTION:A reserving means 2a receives a reserving command, stores a magazine number, a program number and a page number by coded by the teletext program during the projection at a display part 2c into a first memory, after that, the teletext program is sent, and when the teletext program corresponding to the magazine number, program number and page number stored in a first memory 11 is present, this is discriminated and the teletext program is accumulated in a second memory 12. When a 'one-touch reserving key' is operated in a key pad 10, a display means 2c reads the accumulated teletext program from the second memory 12 and displays this at the display part 2c. Thus, by reserving, thereafter, the teletext program can be displayed at the display part 2c only by executing one key operation and operation is made very easier.

Title: Method for preventing hydrogen embrittlement crack of welded structure
Inventor: KAKEHI KATSUYUKI
IPC: B23K31/00
Filed: 1980-07-01
Abstract: PURPOSE: To prevent occurrences of cracks due to hydrogen embrittlement in welded structures, by gluing hydrogen embrittlement resistive materials made of a hydrogen reserving alloy in advance at portions to be welded and their vicinity on welded structures which will be used for hydrogen generating substances.  
     CONSTITUTION: At portions to be welded and their vicinity which are likely to occur hydrogen embrittlement, of welded structures which will be used for hydrogen generating substances, such as spherical tanks for reserving LPG, etc., a hydrogen embrittlement resistive material prepared by mixing powder of hydrogen reserving alloys, such as Ti-Fe alloy, La-Ni alloy, etc., with a binder of teflon and formed to have desired shapes, is glued with an adhesives. Since the hydrogen gas produced from LPG, etc., when these tanks are in operation, is absorbed into the hydrogen reserving alloys of hydrogen embrittlement resistive material, the hydrogen will not be absorbed into the welded portion and heat affected portion in the vicinity, and, therefore, no cracks due to hydrogen embrittlement will be produced.

Title: Production of graphite-containing aluminum alloy
Inventor: KOMURO KATSUHIRO
IPC: C22C1/10
Filed: 1981-06-08
Abstract: PURPOSE: To obtain an Al alloy for lubrication wherein graphite particles having no surface treatments such as metallic coating are disposed with virtually no floating the melting the green compact of a mixture of Al-based metallic powder and the graphite particles as it is or charging the same into molten Al-based metal under agitation.  
     CONSTITUTION: Graphite particles are added and mixed at ≤50vol% based on the volume of green compact to and with any of Al powder, Al alloy powder or a mixture of Al powder and other metallic powder necessary for alloying of Al, and the mixture is molded in such a way that the density ratio of the green compact attains ≥70%. When this green compact (including sintered body) is melted as it is or is charged under agitation into molten Al-based metal, and the molten metal is cooled to solidify, the alloy contg. 4W30wt% graphite based on the weight of the resultant alloy is obtained. Here, the amt. of the graphite is the limit in the case of using the same under dry friction conditions, and if it is below the lower limit, no lubricating effect is obtained and in excess of the upper limit, abrasion resistance and mechanical strength degrade. If the density ratio of the green compact is below the above-described ones, the dispersion of the graphite particles is insufficient and the graphite particles float on the surface of the molten metal.

Title: Ultrasonic liquid atomizer
Inventor: NOBUE TETSUAKI
IPC: B06B1/06
Filed: 1978-07-19
Abstract: PURPOSE: The captioned apparatus which maintains the rate of liquid atomization irrespective of voltage fluctuations, temperature changes and variations in electrostrictive vibrators by mounting an ultrasonic vibrator and liquid level detector to a liquid atomization tank and controlling the driving output of the driving control circuit of the ultrasonic vibrator by the output of the liquid level detector.  
     CONSTITUTION: When liquid is supplied from a constant flow rate supplying device 101, the liquid level in an atomizing tank 102 rises and a float 106 and shielding plate 107 also rise and therefore the quantity of light from the LED 18a of a photo interruptor 18 is reduced and entered to a photo transistor (PT) 18b, whereby the C current of the PT 18b is reduced. Then, the B current of the transistor (T) 23 also decreases and therefore the B current flows in the T 25 which in turn supplies current to the driving circuit B thereby driving the ultrasonic vibrator 10. When the vibrator 10 is driven, the liquid 103 is atomized, hence the rise of the liquid level decreases and stabilizes at the driving level where the rate of liquid supply and the rate of atomization coincide.

Filed: 1990-04-05
Abstract: PURPOSE:To improve maintainability, to reduce failures and also to improve the edging accuracy of material to be rolled by mounting a balancing cylinder on a fixed stand to absorb backlash through vertical roll chocks. CONSTITUTION:Because the fixed stand 9 is immovably erected outside a housing 2 and the case 28 for a nut 27 which is engaged with the thread parts 25 of the screw shaft 25, 26 for adjusting position is attached to the fixed stand 9, the rolling reaction force of a vertical roll 3 can be strongly supported. And, because the balancing cylinder 32 is mounted on the fixed stand 9 and the force due to this cylinder 32 is exerted on the vertical roll chock 20, the backlash of every part between the vertical roll chock 20 and a hydraulic rolling- down cylinder 30 and every parts between the housing 2 and the case 28 for nut mounted on the fixed stand 9 is absorbed. Therefore, the rigidity of the vertial roll mill 1 with side guide is raised and simultaneously the width accuracy of material to be rolled can be improved.

Abstract: PURPOSE:To record an image of invariably good quality by providing a refracting member which refracts illumination light so that regularly reflected light strike an optical system between a light source and an original. CONSTITUTION:This device is provided with a photographed original 1, illumination light source 2, lens 3 for forming an image of the original on a microfilm F, light refracting member 4 consisting of a prism provided between the light source 2 and original 1.

The light refracting member 4 refracts the regularly reflected light of illumination luminous flux from the light source 2 and its refracted light is reflected by the original surface and never reaches the lens 3. The refracted light transmitted through the light refracting member 4 illuminates the original surface or travels away from the original surface. Therefore, the regularly reflected light from the light source 2 never strikes the lens 3 and only diffused refraction light from the original surface enters the lens to prevent the deterioration of the quality of a recorded image due to the regularly reflected light.

Abstract: PURPOSE:To increase the strength of gel and to enhance the yield in both an aging stage and a drying stage by regulating the amount of water and alcohol contained in a hydrolyzed sol soln. in the production of quartz glass by a sol-gel process. CONSTITUTION:In a regulation stage of a sol soln. in the production of quartz glass by a sol-gel process, the amount of water and alcohol contained in the hydrolyzed sol soln. is regulated. Si-O-Si bonding is promoted by removing alcohol in such a method and a large network can be formed, as a result, the strength of gel obtained by this sol is made strong. Further a tridimensional network is easily formed in gel by replenishing water after removing alcohol, and dispersion is made easy in case of adding pulverized silica. Also it can be dried in good yield without violently advancing the drying thereof because the proportion of alcohol is small.
