Title: Measuring method of remaining amount of propellant of astrogating body
Inventor: EGAMI YUKIO
IPC: B64G1/66
Filed: 1984-11-20
Abstract: PURPOSE:To measure precisely the remaining amount of propellant from the latter period to the last period of an astrogating by measuring the thickness (liquid level) of the propellant in a propellant tank by an ultrasonic probe directly. CONSTITUTION:Ultrasonic probes 12 are fitted to the surface of the propellant tank 1 at plural positions and connected to an ultrasonic wave transmitter and an ultrasonic wave receiver. A point on the liquid surface of the propellant 10 is measured by the respective probes 12, measured values from which are processed mathematically to estimate the liquid level shape of the propellant 10 and also calculate the capacity of the propellant 10. Consequently, the remaining amount of the propellant 10 is calculated accurately even when the amount is small. When gravitational force is fine, the propellant 10 is localized in the direction of the fine gravitational force to form an uneven distribution of the propellant, so many ultrasonic probes 12 are preferably provided so as to grasp accurately the liquid surface shape and capacity.

Title: Propulsion method for ship equipped with yawing type propeller
Inventor: HATANAKA KATSUNORI
IPC: B63H25/42
Filed: 1985-11-01
Abstract: PURPOSE:To enable the prevention of interference among a plurality of yawing type propellers on the bottom of an offshore structure and the like by making the upperstream side of propellers rotatable toward an outboard direction about the center line of the bottom. CONSTITUTION:Yawing type propellers 4a and 4b at the upperstream side are directed outboard with an angle of 50 deg. (beta) or less, resisting advance resistance 'R' or an external force 'F'.

Title: Design device for control device
Inventor: TAKEUCHI YOSHITOMO
IPC: G05B15/02
Filed: 1988-09-29
Abstract: PURPOSE:To confirm whether the total point of constituting elements is in the housing ability of a control device or not, etc., at the time of designing and to widely improve design efficiency by displaying that the defining position of a number to correspond to the number of the constituting elements, which are already defined, is already used. CONSTITUTION:For example, when proportion control is selected as control function 62 out of a loop selection menu 61 and defined to a defining position 64 which is correspondent to an arranging order number 9 of a loop design screen 63', the position 64 of a number 9 and the position 64 to a continuous number 10 are allocated at first because the number of constituting elements 65 for the proportion control is two. The symbol of the proportion control is displayed in the position 64 of the head number 9 and used display 68 is displayed in the position 64 of the number 10. This display 64 is also executed in the position 64 of a number 13 to follow a number 12, for which cascade control is defined, to have the same number of the elements 65. Thus, the number of the used positions 64 shows the total point of the elements 65 to be defined up to the moment and at the time of the designing it can be confirmed that a loop control device has the enough housing ability for a part corresponding to the number of the unused defining positions.

Title: Shaft seal device for stirling cycle
Inventor: ITABANE TSUNESAKU
IPC: F16J15/34
Filed: 1990-09-18
Abstract: PURPOSE:To enhance a sealing effect by thinning a thickness of a sealing end surface of a driven ring thereby making the sealing end surface to be recessed at the central portion during sliding, and providing an annular groove near the sealing end surface. CONSTITUTION:A driven ring 142 of a mechanical seal includes a groove 153 formed on the inter peripheral surface and a thinned sealing end surface 142'. The thickness of the thinned sealing end surface is determined at the specified value, and the depth of the groove 153 is determined at the diameter similar to the outermost diameter of the sealing end surface of a seat ring 141. Namely, the surfaces being in contact with the sealing end surface of the seat ring 141 is all specified to be thinned. The thickness of the sealing end surface of the driven ring is thus determined at the suitable value, and consequently it is possible to make the sealing end surface flexible and increase the contact pressure with the seat ring on the outer peripheral side of the sealing end on which high pressure fluid is directly applied, thus enhancing the sealing effect.

Title: Power-supply device for electronic equipement and electronic-equipment system
Inventor: MITO TOSHITSUGU
IPC: H02J9/06
Filed: 1992-09-16
Abstract: PURPOSE: To charge a battery in a short time, while supplying load with a sufficient drive current by feedback-controlling an output from a power supply, so as to reach approximately a constant power on the basis of a voltage feedback value and a current feedback value. CONSTITUTION: When the output voltage V(0) of an AC adapter 20 is made higher than the potential V(Z1) of a Zener diode(ZD) 148A, the voltage feedback value of a feedback path which passed through the ZD 148A does not reach zero, and the voltage feedback value and a current feedback value from a current-detecting resistor 114 are added by an adder 150. Accordingly, a feedback path passed through a differential amplifier 120 is worked as an approximately constant power control feedback means, and an output from the AC adapter 20 is controlled, so as to reach approximately a constant power on the basis of both the current feedback value and the voltage feedback value. The AC adapter 20 supplies a system load with a drive current, while feeding a battery with a surplus power at that time.

Title: Wire electric discharge machine
Inventor: TANAKA MAKOTO
IPC: B23H7/02
Filed: 1986-10-16
Abstract: PURPOSE:To prevent a wire electrode from generating a tilt and to permit high accurate machining to be performed, by providing a means which performs the machining automatically correcting verticality of the first and second wire guides after the wire electrode is supplied to be changed. CONSTITUTION:If an exchange is completed from a wire electrode 1a to 1b, a numerical control unit 20, which calls a corresponding correction value for a vertical error on the basis of wire electrode information from a memory to be added to a predetermined moving amount of a selecting means 16, drives the selecting means 16 so that the first wire guide 9a is vertically placed with respect to the second wire guide 9b. Accordingly, the wire electrodes 1a, b, even if they are exchanged by moving the wire guides 9a, 9b, are always vertically placed with respect to a workpiece 10. In this way, the wire electrode is prevented from generating a tilt, accordingly a machining surface of the workpice is prevented from tilting, thus high accurate machining can be performed.

Title: Original size detector for copying machine
Inventor: OGAWA KAZUO
IPC: G01B11/02
Filed: 1997-09-11
Abstract: PROBLEM TO BE SOLVED: To prevent a life from being shortened because the consumption of a light emitting element and a scanning motor is reduced and also to prevent the occurrence of erroneous detection as a maximum size by starting operation to detect the size of an original in a state wghere copying operation can be started and also when paper is automatically selected. SOLUTION: When an original cover plate 4 is opened and is separated from an original platen 3, a microcomputer detects that the original cover plate 4 is opened by a signal from a switch 26, so that the light emitting element 8 is turned on and also the scanning motor 12 is rotated by the microcomputer. Then, in the case that nonconformity is caused while executing the detection of the original size, the light emitting element 8 is turned off and also the scanning motor 12 is stopped by the microcomputer. Thus, since the detecting operation is started when the copying operation is made possible and the paper is automatically selected, the life is prevented from being shortened without executing unnecessary light emission by the light emitting element 8 nor executing scanning by a light scanning mechanism 7.
