Title: Method of inspecting leakage from closed container
Inventor: HARADA YASUYUKI
IPC: G01M3/26
Filed: 1979-02-06
Abstract: PURPOSE: To inspect the leakage from a closed container in which sealed drinking water, drug, etc., simply by attaching supersonic wave resonance phones to one end of a supersonic wave vibration board so that the vertically vibrating phones may vibrate the board horizontally.  
     CONSTITUTION: One end of a supersonic vibration board 1' is supported by a supporting member 13 provided in a water tank 14, the other end is elevated above medium water 4 and held between supersonic resonance phones 8 and 9 outside the  water tank 14 being composed so that the vertical vibrations of supersonic waves  may be transmitted to the supersonic vibration board 1' as horizontal vibrations at  the loops of the vibrations. The supersonic resonance phone 9 is connected with a  supersonic vibrator 2'. A container to be tested 5 is stood on the supersonic vibration board 1' upside down so that the sealed part of a cap 7 may be immersed in  the medium water 4 and vibrated by supersonic waves. As a result, the inside  pressure of the container 5 rises, and if the sealing of the cap 7 is incomplete, liquid 6 leaks from the sealed part, and so the leakage of the closed container 5 in which drinking water, drug, etc., is sealed can be inspected simply.

Title: Ti alloy combining high strength with high toughness and excellent in local corrosion resistance
Inventor: MAE YOSHIHARU
IPC: C22C14/00
Filed: 1987-01-21
Abstract: PURPOSE:To improve local corrosion resistance, by specifying a composition and adding specific amounts of Mo and Ni in a Ti-Al-V alloy. CONSTITUTION:The Ti alloy has a composition consisting of, by weight, 3-8% Al, 0.1-3% V, 0.1-3% Mo, 0.1-2% Ni, and the balance Ti. This Ti alloy combines high strength with high toughness, and, even if exposed under a high- temp. environment of high chlorine-ion concentration, it hardly causes local corrosion such as crevice corrosion and produces excellent properties. In the above composition, when V content exceeds 3%, hydrogen embrittleness occurs in an aqueous solution. Moreover, though Mo has a function of improving strength and corrosion resistance, the desired effects cannot be obtained when its content is less than 0.1%, while workability is deteriorated when it exceeds 3%. Further, Ni improves strength as well as local corrosion resistance by coexistence with Mo, but the desired effects cannot be obtained when Ni content is less than 0.1% and, when it exceeds 2%, toughness and workability are deteriorated.

Title: Rolling mill
Inventor: NAKAGIHARA MICHITOKU
IPC: B21B13/02
Filed: 1984-01-26
Abstract: PURPOSE:To obtain a rolled material free from roll marks by arranging respective sectional rolls of respective press rolls provided to a work roll mutually and alternately in their axial directions. CONSTITUTION:Rolling is performed for a long time while pressing press rolls 4 against intermediate rolls 3 respectively. Because each sectional roll parts 4a of the press roll 4 is disposed at the position corresponding to the gap H between the sectional roll parts 4a of another press roll 4', the rolls 3 are brought into uniform contact with work rolls 1, 2 respectively. Accordingly, roll marks are produced in the rolls 3, but are eliminated in the stage of transmitting the roll marks to the rolls 1, 2. The roll marks are therefore prevented from generating in the rolls 1, 2, and a rolled material free from roll marks is obtained.

Title: Cleaning apparatus
Inventor: OISHI HIDEO
IPC: H01L21/30
Filed: 1986-01-22
Abstract: PURPOSE:To obtain a cleaning apparatus capable of alarming if a nichrome wire is exposed, by dipping a grounded electrode bar in an electrically conducting chemical liquid and providing an informing unit adapted to be activat ed when a ground fault interruptor detects a ground fault and initiates its opera tion and to inform that fact. CONSTITUTION:A nichrome wire of a heater 12 is electrically isolated from a polysilicon bar 14 by quartz and no ground fault occurs unless the nichrome wire is exposed. Under such conditions, a ground fault interruptor 23 is kept ON. However, if a pinhole or the like is made in the quartz to expose a part of the nichrome wire of the heater 12, the isolation is nullified and electric current flows through hydrochloric acid in a chemical tank 11 and through the polysilicon bar 14 to cause a ground fault. The ground fault interruptor 23 then detects the ground fault and interrupts power supply to the heater 12. A voltage applied to a relay 35 thereby becomes 0V and, therefore, a B contact is closed. Simultaneously, a buzzer 33 starts to buzz, informing the fact that the nichrome wire has been exposed.
