Title: Water level sensor
Inventor: YAMAMOTO MASAHIKO
IPC: F24H1/00
Filed: 1989-02-20
Abstract: PURPOSE:To improve an accuracy of water feeding to a set water level by a method wherein a pressure between a water storing part and a pressure sensor is set to a stable value, the pressure is stored as a water level reference value, the reference value is compared with a previous value at every time, and if there is a difference of more than a specified value of the previous one, the previous one is applied and if the difference is within a specified value, the value will be revised. CONSTITUTION:An operation of a water supplying part 10 is stopped, a changing-over means 12 is changed over to a return pipe 5 at a step 12, a pump 6 is operated to cause water to be circulated through an outgoing pipe 4, a water storing part 1, a returning pipe 5 and a pump 6. At this time, since air is leaked at the water storing part 1, it shows a stable value PO. If the circulating mode operation is terminated, the changing-over means 12 is connected again to the water supplying pipe 11 to change-over to a water supplying mode. If a pressure value is a difference more than a specified value as compared with the previous water level reference value, the previous one is used as the water level reference value. In turn, if the value is less than the specified value, a present value is revised as a water level reference value at a step 20 and stored. If the set value water supplying is fed to a point where a pressure PA is increased, the value becomes the set water level and since the value of PO+PA is in a stable value, it may easily be returned back to the set position even in case of replenishment with water.

Abstract: PURPOSE:To form the finer crystal grains in the weld zone of an electric welded steel pipe having a specific compsn. contg. Nb and to obtain the high-toughness electric welded steel pipe by subjecting the weld zone after welding of said pipe to a special heat treatment. CONSTITUTION:The electric welded steel pipe is produced by using a steel contg. <=0.30wt.% C, <=2.0% Mn, <=0.80% Si, 0.01-0.10% Al, and 0.01-0.15% Nb, contg. >=1 kinds of 0.01-0.20% V and 0.005-0.100% Ti and consisting of the balance Fe and unavoidable impurities as a stock.

Title: Air leak tester
Inventor: FUKUDA RYO
IPC: F17C5/00
Filed: 1991-02-13
Abstract: PURPOSE:To suppress the influence to the pressure inside an inspected body due to the heat generation and correctly carry out air leak test suppying a high electric current to a solenoid valve when the solenoid valve is switching- operated and supplying a low electric current after the switching operation. CONSTITUTION:When a switch 13 is turned ON, electric current is supplied to a coil 30, and a solenoid valve 5 is switched from an ening position to a closing position. In this case, a relatively high charging voltage VH of a condenser 12b is applied into the coil 30, and a large electric current corresponding to the exciting force which is necessary for the switching operation is supplied by the electric discharge of the condenser 12b, and the electric discharge of the condenser 12b is completed when it reaches a voltage VL. The solenoid valve 5 is supplied with the electric current corresponding to the voltage VL, and holds a closing position. Since the supplied current is small, in compsrison with the electric current in the selection operation, the calorific heat generated in the coil 20 can be suppressed small, and when the solenoid valve 5 is at the closing position, the influence to the pressure of an inspected body A due to the heat generation can be suppressed to a low value.

Title: Evaluation of composite film
Inventor: MATSUZAKI KOJI
IPC: G01N25/18
Filed: 1987-02-24
Abstract: PURPOSE:To evaluate the compositional ratio or fine structure of a composite film by a single method, by measuring the heat diffusivity of the composite film in the surface direction thereof by an intermittent heating method. CONSTITUTION:When light energy is allowed to intermittently irradiate a composite film 1 by rotating a chopper 3, the part irradiated with the light energy of the composite film 1 is heated to rise in its temp. Since the light blocking part of the composite film 1 does not rise in its temp., a temp. gradient is generated between the light irradiated part and the light blocking part and a cyclic heat wave advances in the surface direction of the composite film 1 and, therefore, the AC temp. of the spot welded point thereof can be measured by a thermocouple 6. This AC temp. reflects the heat diffusivity of the composite film 1. At this time, when a mask member 2 is allowed to approach the thermocouple 6 or to get away therefrom at a predetermined speed, the AC temp. detected by the thermocouple 6 rises or lowers. When heat diffusivity is measured by intermittent heating, since the heat diffusivity is not affected by the dimension of the composite film 1, the compositional ratio of the composite film 1 can be simply and rapidly evaluated.

Filed: 1985-03-01
Abstract: PURPOSE:To lower a driving voltage and to eliminate irregularity in fixation by providing a means which drive respective discharge tubes which are divided at right angles to the moving direction of a recording material on time-division basis. CONSTITUTION:The respective xenon lamps (Xe lamp) 16a, 16b, and 16c which are divided at right angles to the moving direction of the recording material illuminate repeatedly in order on time-division basis through a time-limit dividing means. Consequently, the recording body has respective areas fixed in the order of A1, B1, C1, A2, B2... and the Xe lamps illuminate repeatedly until the transfer paper P is fixed entirely; and the Xe lamps are made to stop illuminating when the whole of the transfer paper P is fixed. In this case, the timing of illumination is so set that there is no gap between adjacent fixation areas, e.g. A1 and A2 in the moving direction of the transfer paper; and the Xe lamps 16a, 16b, and 16c are so arranged that there is no gap between adjacent fixation areas, e.g. A1 and B1, and B1 and C1 at right angles to the moving direction of the transfer paper. Thus, the driving voltage is lowered and irregularity in fixation is eliminated.

When the pushbutton switch 15 is depressed to invert the polarity of a DC voltage applied to the signal line 3, the light emitting element 25a goes off and the output level of the comparator 27 goes to 'L', then the display light 29 is lighted.
