Title: Manufacture of alloy by ultrasonic waves
Inventor: BABA AKIRA
IPC: C22C1/02
Filed: 1982-07-20
Abstract: PURPOSE:To obtain an alloy having predetermined components, while contriving to change its metallurgical structure into a finely and uniformly dispersed state, by immersing a rod composed of an additional element having a m.p. higher than that of a basic metal in the melt of said basic metal, and applying ultrasonic waves through said rod to the melt. CONSTITUTION:An alloy of Al having a m.p. of 660 deg.C mixed with Fe having a m.p. of 1,539 deg.C, for instance, is manufactured in the method as follows: Rod steel 6 is immersed in the melt 14 of the Al underneath held at 700 deg.C by the control of a heater. Oscillation of 20kHz is applied from an ultrasonic oscillator through piezoelectric transducers 7, 9 to a Type L-L transducer being used as a transducing body 5. Hereon, the rod steel 6 is fixed with a fixing tool 15 in a manner such that the length from its lower end comes to an integer times the half-wave length to obtain the maximum amplitude at the top end of the rod steel 6, since the oscillation of the rod steel 6 at the lower end of the transducing body 5 comes to the node of the amplitude. Thus, the rod steel 6 is continuously and steadily dissolved in the melt 14 to obtain the Fe-dissolved Al alloy. In the Drawing, (b) represents the node part of the oscillation amplitude (a) of the rod steel 6.

Title: Power source circuit
Inventor: NAGAI TAMIJI
IPC: H02J1/00
Filed: 1983-07-08
Abstract: PURPOSE:To supply power of the magnitude corresponding to the power of a power source to be supplied by operating ON and OFF by an intermittent oscillator for a switching element when a power is supplied to a small power load. CONSTITUTION:When power is supplied only to a small power load 41, a changeover switch 42 is turned OFF. Thus, a drive output is not applied to an oscillator 4 and a pulse width modulator 5, and a control signal is not applied to a transistor 45 which becomes OFF state. Accordingly, an intermittent oscillation occurs through a feedback circuit which has a switch transistor 2, a resistor 22A, capacitors 21A, 21B and a resistor 22B, and an intermittent oscillation loop of a transformer 6 and a capacitor 16, thereby delivering a DC output of small power to an output terminal U21.

Title: Device for detecting boundary between solution and solvent in nuclear fuel reprocessing apparatus
Inventor: MIURA IWAO
IPC: G01F23/64
Filed: 1981-08-11
Abstract: PURPOSE:To detect the boundary surface with high accuracy by an apparatus wherein an ultrasonic wave is transmitted to a boundary float floating at the boundary between the solution and the solvent, and a time period until receipt of the reflected wave is measured. CONSTITUTION:A boundary float 108 is formed of synthetic resin material to be floated at a position of the boundary 105. The boundary float 108 is shaped into a star-like or other form in plan view, so that a solution 103 and a solvent 104 separated from eachother are not prevented from floating. A reflection plate 109 formed of corrosion resistanct metal material is attached at the upper central surface of the float 108 to effectively reflect a ultrasonic wave from a ultrasonic transducer 111. An ultrasonic wave radiated downward through a solvent float 110 is reflected by the boundary float 108 and the bottom surface of an extracting tank 101. Thus reflected wave is received by the ultrasonic transducer 111, and positions of the boundary float 108 and the solvent float 110, i.e., levels of the boundary 105 and the liquid surface of the solvent 104, is calculated by a signal processing circuit 114 based on a time period until receipt of the reflected wave.

Title: Optical recording medium and its production
Inventor: OGAWA YOSHIHIRO
IPC: G11B7/24012
Filed: 1989-05-18
Abstract: PURPOSE:To prevent warpage of a medium which is apt to appear when different kinds of materials are used to satisfy the requirements as a substrate and a protective substrate, and to improve reliability of the medium by providing a correcting layer according to warpage so as to shrink the surface of the protective substrate. CONSTITUTION:A flexible correcting layer 6 is provided on the outer surface of a protective substrate 5'. The surface of the protective substrate 5' is made to shrink by shrinking the correcting layer 6.

Title: Stabilization of vitamin c and production of stabilized vitamin c preparation
Inventor: HOSOYAMA HIROSHI
IPC: A61K9/16
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To provide a method for stabilizing vitamin C in an inexpensive and simple way, by adding proanthocyanidin to vitamin C and mixing them. SOLUTION: This method for stabilizing vitamin C comprises adding natural proanthocyanidin having various physiological activities including antioxidative activity to vitamin C and mixing them. The quantity of the proanthocyanidin to be added is >=1 wt.%, preferably, 25-200 wt.%, based on the vitamin C (as ascorbic acid). Concomitant use of a chelating agent in the mixing is preferable, because of its chelating metal ions causing vitamin C decomposition and of enhancing the vitamin C stabilizing effect. Stabilized vatamin C preparations are obtained by dissolving vitamin C and proanthocyanidin in water, and transforming the solution to a powder according to a conventional method.

Abstract: PURPOSE:To enable highly accurate measurement of temperature with a low bit level A/D converter, by arranging a means to input a temperature signal from a temperature sensor direct into an A/D converter of a microcomputer CPU and a means to input the signal once subjected to a differential amplification. CONSTITUTION:Temperature information of temperature sensors 1 and 2 is inputted into a 8-bit A/D converter 10 of a CPU 9 as temperature signal T directly or via a differential amplifier 8. A selectively setting circuit 14 picks up divided voltages at contacts of resistors 15 (resistances R1-R7 and VR) by an output signal from the CPU 9 to be applied to the differential amplifier 8 so that an operation area of the amplifier 8 is set variably. Thus, a rough measuring temperature level is judged by a signal T inputted direct into the converter 10 from the sensors 1 and 2 in an early measurement to specify measuring temperature areas T1-T7. A reference voltage for differentiation corresponding to the specification is set selectively to operate the amplifier 8 and the signal T is amplified with the amplifier 8 for each of the areas T1-T7 to be inputted into the converter 10 thereby achieving higher resolutions of an A/D conversion data b with the converter 10.
