Title: Defoaming agent
Inventor: YAJIMA AKIMASA
IPC: B01D19/04
Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To remove hindrance to etching due to foams with an extremely slight amount of a defoaming agent by containing one or more compounds selected from among an alcohol sulfate, an alcohol alkoxysulfate, an alkylbenzenesulfonic acid, an alkylnaphthalenesulfonic acid, and their salts as indispensable components. SOLUTION: A defoaming agent for an etching liquid contains one or more compounds selected from an alcohol sulfate, an alcohol alkoxysulfate, an alkylbenzenesulfonic acid, an alkylnaphthalenesulfonic acid, and their salts as indispensable components. As it is clear from the fact that these sulfate compounds and sulfonic acid compounds are main components of detergents for domestic use and industrial use, their water solubility and dispersibility in water are extremely good. That is, these compounds have extremely high defoaming effect in the etching liquid and remove hindrance to etching due to foams though these compounds have high hydrophilicity and high defoaming property in a normal aqueous solution.

Title: High-frequency heating device
Inventor: TERASAKI HIROSHI
IPC: H05B6/74
Filed: 1988-02-29
Abstract: PURPOSE:To suppress an abnormal heating at the periphery of a loading table by making the distance between a bottom wall opposite to the loading table shorter than the rotation area of a churning plate in which the electric field is varied, concentrating the high-frequency energy to the loading area of a substance to heat, and ventilating between the loading table and the bottom wall. CONSTITUTION:The heating device is composed to rotate a churning device 9 of electric field along almost all the area of the loading area of a substance to heat 10, and the substance 10 is heated by a strong and even electric field. Although the loading table 11 is heated at the same time, the heat is absorbed to the substance 10. In this case, the distance between the bottom wall 3 and the loading table 11 is made shorter than the set area of the substance to heat 10, to weaken the electric field applied to the loading table 11. Furthermore, through ventilating holes 25-29 furnished where the distance between the loading table 11 and the bottom wall 3 is shorter, the ventilation at the part is carried out to apply a cooling air. An abnormal heating at the periphery of the loading table can be prevented consequently.

Title: Belt for continuous casting
Inventor: MIYAHARA MITSUO
IPC: B22D11/06
Filed: 1987-02-27
Abstract: PURPOSE:To reduce camber quantity of a belt, prevent unequal cooling in a cast slab and to obtain the stable quality by using combined clad steel plate joining two kinds of the steel plates having different coefficients of linear expansion to the belt for continuous casting of a twin belt type continuous casting machine. CONSTITUTION:Outer face side of the belt, which becomes high temp. by contacting with molten steel or the cast slab, is made of the steel plate 21 having small coefficient of the linear expansion and its inner face side at cooling side, is constituted by the steel plate 22 having large coefficient of the linear expansion. In this way, thermal strain at the inner face side (low-temp. side) is made to more than that of the conventional single steel plate-made belt, to restrain the camber quantity of whole steel plate, i.e. the belt itself to a little. As the camber quantity or deforming quantity becomes a little, the service life becomes long. Further, as the deforming quantity of the belt is reduced, and variation of the molten surface near pouring part of the molten steel and the unequal cooling in the cast slab are prevented and the cast slab 5 having the stable quality is obtd.

Title: Oxide superconductor and its production
Inventor: MATSUMOTO MITSUHIRO
IPC: C04B35/45
Filed: 1988-02-29
Abstract: PURPOSE:To obtain the subject superconductor with increased relative density and improved mechanical strength and critical current density by calcining a raw material contg. a rare-earth element and having a specified composition, and sintering the secondary raw material wherein the powder X-ray diffraction intensity ratio of the unreacted product is controlled to a specified value. CONSTITUTION:The raw powder or synthetic raw material having a composition shown by the formula (RE = rare-earth element) is calcined at 800-920 deg.C in the atmosphere or in oxygen, and the secondary raw material, wherein the powder X-ray diffraction intensity ratio of the unreacted product is controlled to 0.03<=I/I0<=3.0, is sintered to obtain the sintered superconductor. Since the plate crystal of the formula (preferably >=5mu) and crystallites of <=1mu size are mixed in the superconductor, the space between the plate crystals are filled with the crystallites, and a structure having a small number of pores is obtained. In addition, although the structure is densified, oxygen diffuses through the many grain boundaries consisting of crystallites, and hence the excellent characteristics of the superconductor reaches the inside of the sintered body.

Title: Voltage detecting circuit and air conditioner applying the voltage detecting circuit
Inventor: KOBAYASHI TAKEHIRO
IPC: F24F11/02
Filed: 1990-02-27
Abstract: PURPOSE:To obtain a voltage detecting circuit showing superior response characteristics to the voltage change thereby to prevent the degradation of efficiency due to the decrease of a source voltage and breakage of a part of an air conditioner which applies the voltage detecting circuit, by converting a divided alternating current voltage to be detected to a pulse signal, measuring the time from the rise or fall of the pulse signal to a zero cross point, and calculating the voltage. CONSTITUTION:A voltage of an alternating current source 1 is divided with use of a diode 3 and a voltage dividing circuit 11 comprised of resistances R1, R2. The voltage is converted to a pulse signal by a photocoupler 12. On the other hand, a zero cross point is detected by a zero cross point detecting means 14. The time t1 from the zero cross point to the rise of the pulse signal is measured by a time measuring means 16 and operated at a voltage operating means 17. In this case, a pulse of narrow width is output when an effective voltage is 90V. However, if an effective voltage is 90V or more, a pulse of large width is correspondingly output. Therefore, the voltage is detected by measuring the time from the zero cross point of the voltage waveform to the rise of the pulse signal. In this manner, a detecting circuit with superior response characteristics to the change of voltage is obtained. If the detecting circuit is applied to an air conditioner, the air conditioner is stopped at 80V or lower.
