IPC: F04F1/18
Filed: 1990-11-30
Abstract: PURPOSE:To prevent corrosion inside a device and breakage by freezing by arranging a gas storing vessel for storing not-yet-melted gas in a piping for an accumulator, in a fine bubble generating device utilized for cleaning a bathtub or water tank or oxidizing a fish breeding tub and so on. CONSTITUTION:A gas storing vessel 11 of a volume of such as the volume at the time when gas has expanded becomes larger than the whole volume inside a device of an accumulator 4 liquid supplying tubes 1a, 1b, 1c, and so on is projectingly installed in the upper part of the accumulator 4. When water in a bathtub is drawn by drive of a pressurizing pump 3, gas is drawn from a gas feeding pipe 2, pressed and melted in the pressurizing pump 3, and carried to the accumulator 4 in a state containing gas not yet melted. Surplus gas not yet melted is separated form liquid, and stored into the gas storing vessel 11. Liquid in the accumulator 4 is discharged into the bathtub form a nozzle 10 provided in discharge port 9 through the liquid supplying tube 1c. At this time, gas pressurized and melted into water becomes fine bubbles. When the device is stopped, the gas in the gas storing vessel 11 is expanded, and rapidly removes remaining liquid inside the device.

Title: Reference mark detecting device
Inventor: OGURA YUTAKA
IPC: G01B11/00
Filed: 1990-11-30
Abstract: PURPOSE:To eliminate the detection error of a datum mark due to deflection of a substrate and enable the inhibitation of vibration to the lesser extent, by using an image pickup lens, which is telecentric on the object side and whose focal distance id short, in an image forming optics system of an image pickup device. CONSTITUTION:A stop 7 is provided on the back side focal plane of an image pickup lens 3 being telecentric on the object side, a major light ray ML parallel to an optical axis 'a' on the object side is passed through the center of the stop 7 such that the position of an entrance pupil points at infinity and the position of an exit pupil points the back side focal position, so that its focal distance is shortened as much as possible. Since the major light ray ML becomes parallel in the space facing the object so that image height is not varied although an image on an image forming plane C is out of focus even when a position of a reference mark 2 in the optical axis 'a' is scattered due to deflection of a substrate 1, the position of a mark 2 can be accurately detected without error. Furthermore, since the height from the substrate 1 in the device can be reduced by using a telecentric lens 3, vibration upon the measurement of the device on the substrate 1 can be suppressed to the minimum.

Title: Flow rate regulation valve and flow rate regulation system
Inventor: WATANABE YASUSHI
IPC: F16K31/00
Filed: 1999-11-30
Abstract: PROBLEM TO BE SOLVED: To hold the opening of a valve hole in a prescribed, value even if the electric power supply to a drive machine is stopped by rotating the rotary shaft of the drive machine by an ultrasonic vibration. SOLUTION: The drive machine 4 of a flow rate regulation valve 7 is constituted by an ultrasonic motor and the vibration of an ultrasonic wave area is generated on the upper surface of a stator by supplying the high frequency voltage having the frequency of several decades kiro-cycle extent to the piezoelectric element 25 of a stator 23 and a rotor is rotated by this vibration. Therefore, when the opening of a valve hole is set in a prescribed value, even if the electric power supply to the drive machine 4 is stopped, as the rotor 26 is press-contacted to the stator 23 by a push-press force of a pressurization spring 27 in the drive machine 4, the rotary shaft 18 is held and fixed and the opening of the valve hole is kept in a prescribed value.  Thus, as the rotary angle of the drive machine operated by the ultrasonic wave vibration is controlled by the number of vibration of the high frequency voltage, the resolving power is extremely high and controlled in a high accuracy and moreover there is not mis-operation by a surrounding magnetic force.

The frequency of the VCO is 2Fck and fed to a camera head 1 through a signal separator circuit 8. On the other hand, the pulse PHP is fed to a color sampling pulse generator 17 to generate a color sampling SP1 and SP2 of an opposite phase to a phase of a color sampling pulse SP1 with a 2Fsc from a CCD drive signal generator 15.  Since only the PHP pulse is added, the circuit for the CVS is simplified.

Abstract: PURPOSE:To perform a temperature cycle test efficiently by keeping the load or displacement of a ample constant, imparting the temperature cycles to the sample by a plurality of times, and measuring the displacement or the load at this time in association with temperature. CONSTITUTION:A load is imparted to a sample 11 made of shape memory alloy material with a load mechanism 10. The load which acts on the sample 11 is detected with a load cell 12. The amount of the displacement of the sample 11 is detected with a displacement gage 13. At this time, the sample 11 is provided in a constant temperature oven 14 having a heating device 14H and a cooling device 14C. The load or the displacement amount is kept constant based on the detected signals from a temperature detector 14D for detecting the temperature of the sample 11, the load cell 12 and the displacement gage 13. Under this state, temperature cycles are imparted to the sample 11 from a control device 15. Since the sample 11 is elongated and contracted in response to the temperature, the displacement or the load at this time is measured in association with the temperature. Thus, the temperature cycle test of the shape memory alloy can be performed efficiently.
