Title: Leakage testing device
Inventor: KOBAYASHI TOSHIAKI
IPC: G01M3/26
Filed: 1994-08-04
Abstract: PURPOSE:To provide a leakage testing device which can accurately perform leakage tests regardless of the magnitude of leakage and can be restored from a faulty state in a short time. CONSTITUTION:At the time of measuring leakage from a container 2 to be tested based on the differential pressure generated between a reference container l and the container 2 which have been adjusted mutually the same internal pressure, a reference pressure sensor 11 which detects the internal pressure of the container 1 and pressure sensor 12 for measurement which detects the internal pressure of the container 2 are provided in addition to a differential pressure sensor 7 which detects the differential pressure between the containers 1 and 2. Therefore, even when the leakage from the container 2 is large and exceeds a measurable range of the sensor 7, the differential pressure can be detected from the difference between the detecting values of the sensors 11 and 12. In addition, the cause of a fault can be analyzed or a faulty part can be specified from the internal pressures of the containers 1 and 2.

Title: Improved immunity measuring method
Inventor: TOKUDA CHIKASHI
IPC: G01N33/543
Filed: 1989-07-18
Abstract: PURPOSE:To make it possible to perform highly sensitive measurement in a short time under the state wherein non-reacted material is removed by performing reaction between a material to be measured and an antibody in a liquid phase, fixing the composite formed of the material to be measured and the antibody in a solid phase, and detecting the material by using a label. CONSTITUTION:The effects of the minute amounts of CEA (carcinoembryonic antigen) and TSH are conspicuous for a material to be measured. As a label, label enzymes for various immunity measuring methods and others are can utilized. As an immunobilizing antibody, a biotin antibody is suitable. Said antibody can be readily fixed to a solid carrier to which avidin is bonded by avidin-biotin bonding reaction. Thus, the composite can be fixed to the solid carrier securely in a short time. At this time, the non-reacted labeled antibody can be separated from the composite. The composite is made to be a sandwich constitution by holding the material to be measured between the fixing antibody and the labeled antibody. When the fixing antibody is utilized, the reaction with the specimen can be performed in a liquid phase. Then, the label is detected, i.e. enzyme activity is measured, and the concentration of the material to be measured can be found.

Filed: 1982-10-19
Abstract: PURPOSE:To obtain a safe and inexpensive latent heat accumulating apparatus, by preventing outflow of a heat accumulating medium into a heating medium due to corrosion of containers of heat accumulating elements by employing such an arrangement that the outer wall surface of a heat accumulating tank and the containers of heat accumulating elements having a latent heat accumulating medium sealed therein are partially held in thermal contact with each other. CONSTITUTION:Holes 8 are formed in the outer wall surface Fe of a heat acculating tank 1 to extend through the inside the tank, and containers 4 for heat accumulating elements 100 having a latent heat accumulating medium 3 such as sodium acetate (CH3 COONa.3H2O) sealed therein leaving the space for absorbing the volume expansion caused by melting of sodium acetate are inserted into the holes 8. Since, with such an arrangement, exchanging of heat between the heat accumulating medium 3 and water 7 is effected by the intermediary of the containers 4 and the tank 1, mixing of the heat accumulating medium 3 into water 7 can be prevented. If aluminum is selected as the material for the containers 4 of the heat accumulating elements 100, there is aroused such a problem that corrosion is caused when they are immersed in water. However, this problem is solved by selecting proper materials for each part, so that it is enabled to provide an inexpensive heat accumulating tank used for various purposes.

When a door member (not shown in the figure) is closed, the tip 22a presses the piece 40b downward. Then the part 40a moves up to release the hook with the part 41a. When the door member is opened after the recording/ reproducing is over, the tip 22a goes up to release the hook with the piece 40b.  Thus the bar 40 is automatically discharged towrad E. In such a way, a disk  cartridge can be loaded and unloaded in an easy way.

Filed: 1990-07-12
Abstract: PURPOSE:To improve display quality by connecting a fluorescent display tube filament halfway to a specific switching element, applying a DC voltage which has a filament voltage rated value to this circuit, and controlling the filament frequency. CONSTITUTION:The DC voltage which has the filament voltage rated value is applied to the drains of MOSFETs Q1 and Q2. When a switching control signal CNT.SIG is at low level, the Q1 and Q2 are off and a control signal is inverted by an inverter 7 to high level and when the signal is inputted to a level shift circuit 6, the Q2 and Q3 turn on to pass a voltage Ef, applied through the filament 4 from the Q3, so that a current flows to the ground GND from the Q2. When the control signal goes up to the high level, Q1 and Q4 connected to the circuit 6 turn on and the signal is inverted by the inverter 7 to turn off the Q2 and Q3, so that a current flows in the order of the Q1, filament 4, Q4, and GND with the voltage Ef of the drain of the Q1. Therefore, the voltage having the polarity controlled with the control signal, i.e. the AC voltage Ef is applied to the filament 4.
