Inventor: ARAI MANABU
IPC: B22D11/10
Filed: 1990-02-20
Abstract: PURPOSE:To accurately detect involution of air into molten steel with variation of induced voltage by setting a primary and a secondary coils surrounding an air seal pipe, conducting Ac current to the primary coil to generate the magnetic field and generating the induced voltage to the secondary coil. CONSTITUTION:The primary coil 1 and the secondary coil 2 are set so as to be supported with a supporting device 28 surrounding and supporting the air seal pipe 26. At the time of conducting the AC current to primary coil 1, the magnetic field through the primary coil 1 and the secondary coil 2, is generated. Under condition of filling up the molten steel in the air seal pipe 26, the induced voltage becomes near zero. When the air in atmosphere comes to be involved into the molten steel by deteriorating the sealing property of a packing 27, as the magnetic permeability varies so as to become larger, the induced voltage becomes larger value than zero. By this value, the involution of air can be accurately detected.

Title: Ultrasonic inspection method
Inventor: SEKI MASAHIRO
IPC: G01P13/00
Filed: 1993-02-03
Abstract: PURPOSE:To make it possible to observe the flow of solvent-particulates suspen sion which can not be visually obserbed by using as a tracer a particulate of which the specific gravity is same as the suspension and the particle size is similar to that of the suspended particulate. CONSTITUTION:Magnetite Fe2O43 is spread on a hollow glass bead 2 so as to control the specific gravity. Control of the specific gravity is adjusted by the thickness of the magnetite layer. By adjusting the specific gravity of a tracer same as that of water, the tracer is moved along the flow of water. The sensitivity of detection level of a reflecting signal is lowered, speckle signal reflecting from particulates are reduced, and hence the sensitivity is adjusted so as to detect a strong reflecting signal generated due to resonance from the tracer. In this way, even in the condition of generating speckles, the flow can be inspected by pursuing the tracer. Namely, the flow of solvent-particulates suspension which can not be observed hitherto can be observed.

Title: Hot water storage type long-time heat storage tank
Inventor: YASUKAWA KEIICHI
IPC: F24S90/00
Filed: 1979-04-03
Abstract: PURPOSE: To make it possible to store heat for a long time, by a method wherein a group of water tanks are formed in a coaxial multi-layer structure, and for each water tank surrounding the center water tank, latent heat material is filled in the gap between the wall having heat-aiding material and the heat insulator, and a heat divider is provided at the bottom of coaxis of the group of water tanks.  
     CONSTITUTION: Water is poured from water supply pipe 25 into water tank A, and a proper amount of water is stored in water tank A, water tank B and center water tank N. When th temperature of heat collector 5 rises and temperature difference relay THS operates, hot water is ejected from the ejection port of return flow pipe 6 by pump P 1 . The hot water collides with buffer plate 13, and instead of flowing directly into center water tank N, is disperses at center frame 7 and reaches the uppermost part N' of frame 8. Here, if the inner temperature of N' is higher than the inner temperature of N, it goes up into N chamber. But, if the inner temperature of N' is low, it flows into outer water tanks in succession and raises their temperatures successivly. By the melting of the latent heat material of each water tank, heat is accumulated. Consequently, the center water tank is maintained at relatively high temperature at all times, so that it is possible to store heat for a long time.

Title: Heat cooking appliance
Inventor: ENDO MINORU
IPC: F24C7/08
Filed: 1995-02-28
Abstract: PURPOSE: To conduct cooking excellently irrespective of the amount of foodstuff, a supply voltage and a power supply frequency by a method wherein the number of square receivers placed in a heating chamber and the amount of the foodstuff put in the square receiver are recognized on the basis of information on the detected number of revolutions of a hot air circulating fan. CONSTITUTION: When square receivers 2 are put on two stages in a heating chamber 1 or the shape of foodstuff put in the receiver is large, a balance of circulation of hot air coming in from an intake port of the hot air and going out from an exhaust port thereof in the rear side of the heating chamber 1 is lost and the number of revolutions of a hot air circulating fan 4b is affected thereby and decreased. Based on information on the decreased number of revolutions of the hot air circulating fan 4b detected by a revolution number detecting means 6, in this state, a control part 8 detects indirectly the number of the square receivers 2 placed in the heating chamber 1 and the amount of the foodstuff put in the square receivers.  Based on this detection, the number of revolutions is increased to about 1800RPM so as to make up for the insufficiency of torque, and a failure due to fluctuation of a voltage frequency is eliminated.
