Title: Heating method and apparatus used for detection of latent stress of construction
Inventor: OHAMA SHIGEO
IPC: G01M99/00
Filed: 1990-01-23
Abstract: PURPOSE:To enable heating used to detect a latent stress of a construction applicable for a metallic construction and measurable accurately by pressing a heating body direct on a structural surface to heat a specified area thereof instantaneously. CONSTITUTION:A number of wire strain gauges 14 are stuck at a specified part (n) of the surface of a construction M at a fixed interval beforehand. A heating body 10 is pressed on a specified area (m) gripping a grip rod 13 and under such a condition, when a switching element 11a is closed after a time of a variable timer relay device 6 is set, a direct current of a power source 4 flows between both pole plates 8 and 9 at the tip of a lead 7 and with this energization, the heating body 10 reaches about 200 deg.C instantaneously while the area (m) rises to about 200 deg.C instantaneously. This temperature is a minimum and enough to generate a thermal stress in the area (m). In addition, as a temperature rise of only about 5 deg.C is noted at a part (n), the gauge 14 operates without deterioration in characteristic by heat, thereby enabling catching of a surface strain with a latent stress and a thermal stress overlapped.

Title: Method for reforming slag on molten steel
Inventor: HARA YOSHIAKI
IPC: F27D15/00
Filed: 1989-01-23
Abstract: PURPOSE:To reduce molten slag quantity flowing into a ladle and Al2O3 quantity in molten steel generated by deoxidation with Al in the ladle by adjusting MgO content and basicity during refining to the specific values at the time of refining from molten iron to the molten steel in a converter and deoxidizing in the ladle. CONSTITUTION:The molten iron reduced to <0.030wt.% P by executing pre- dephosphorizing-refining to the molten iron from a blast furnace, is charged into the converter to produce the molten steel with decarbonizing-reaction by oxygen-blowing. In this case, by making the basicity of the molten slag at the time of stopping the blowing the high value of >=5.5, the molten slag temp. comes to high and in the case of discharging the molten steel into the ladle, the quantity of the molten slag flowing into the ladle together with the molten steel is reduced, and also by making >=9.5% MgO content in the molten slag, FeO content in the molten slag at the time of stopping the blowing is reduced. Therefore, the high purity molten steel with Al2O3 content drastically reduced as non-metallic inclusion generated at the time of deoxidizing-refining by adding Al into the molten steel in the ladle, can be stably produced.

One output is inputted into a delay circuit 20 and delayed by a delay time T. Both outputs are amplified by a logarithmic amplifier 22 through an adder 21, and a peak value is detected by a peak value detecting circuit 23. The peak value is sampled and held in sample hold circuits 24 and 25 by sample hold signals E16 and E17 which are shifted by a delay time T, and a difference is obtained by a subtractor 28. The output E20 is sampled and held by a signal E21,  which is synchronized with the sample hold signal E17, and the output is obtaind.

Title: Robot arm device
Inventor: NOOMAN BURAIAN PIGOTSUTO
IPC: B25J18/06
Filed: 1986-01-23
Abstract: A robot arm (10) is mounted at one end by means of a ball and socket joint (20, 22). The ball and socket joint permits angular movement of the arm whilst retaining a large area of contact between the ball and the socket. Angular movement of the arm is effected by means of driven links (24 and 26) which pull or push the arm in a desired direction. However, thrust loads on the arm during operation are transferred to the ball and socket joint and are not transmitted to the drive mechanism.

Title: Conduction heater
Inventor: GANJI NOBUO
IPC: A47J27/21
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To improve heat exchange between heating metal and liquid by providing a gap of a prescribed interval between a heating metal plate and a glass vacuum double vessel and providing a hole or a slit on the heating metal plate. SOLUTION: By making the heating metal planar and providing a gap more than 0.5mm between the metal and a heat insulating vessel, a liquid also touches the downside of a heating metal plate 17, the surface to exchange heat is widened, and heat exchange is improved by promoting circulation by providing a hole on the heating metal plate 17. Namely, a glass vacuum double vessel 12 makes a gap between outer and inner bottles 13 and 14 into vacuum and prevents heat conduction caused by the circulation of air. An external case 15 prevents impulse from being loaded from side and upper faces to the glass vacuum double vessel 12. An elastic body 18 for heating water 16 by sinking the heating metal plate 17 onto the bottom of the heat insulating vessel is formed e.g. from silicone rubber, and sounds generated by vibrations at the time of boiling are prevented.  A device 19 for generating a high-frequency magnetic field is composed of a heating coil 20 and a circuit 21 for letting a high-frequency current flow to the heating coil.

Filed: 1995-01-31
Abstract: PURPOSE: To suppress the background signal component caused by the radioactive gas and allow a high-accuracy analysis by arranging at least a pair of a scintillator and a photomultiplier as an amplifier of the ion signal. CONSTITUTION: Specific ions 12 mass-separated by a four-pole piece electron section 5 are fed to an ion-electron converting electrode 13, and secondary electrons are emitted. The secondary electrons pass through an aluminum film 15 and collide with a scintillator 16 to generate the number of photons proportional to the number of incident electrons, and the photons are fed to a photomultiplier 19 to generate a pulse current. When the photomultiplier 19 covered with a glass tube on the whole secondary electron multiplier is used to detect the ion signal as the light signal, the adsorption area of the radioactive gas to the secondary electron multiplier can be reduced. When the adsorption area is reduced, the adsorption quantity of the radioactive gas is also reduced, and the background signal is sharply reduced.

An energy analyzing part 14 specifies the block of the MRA, based on the secondary key and calculates the energy of the transformation factor for MRR (plural frequency bands other than the lowest frequency band), corresponding to the same spatial expression area at the block position.  When the energy is a prescribed set value or larger, an information embedding part 15 embeds digital information in the transformation factor in the block of the MRA. A band combining part 16 combines the MRA after the embedment processing with the MRR, and reconstructs an image signal 72.
