Title: Tube pump
Inventor: SAEKI RIYOUJI
IPC: F04C5/00
Filed: 1991-11-13
Abstract: PURPOSE:To eliminate a pulsating flow and to decrease damage of a tube by setting the tube in a condition that it is wound by one turn into a spiral or coil shape, and providing endlessness in action. CONSTITUTION:By setting a tube 1 into a spiral or coil shape, an endless condition is made in action. That is, the tube 1 is wound by one turn into the spiral shape on a disk pan 13 and placed in a condition that both ends of the tube are drawn out to the outside from pull ports 14, 15 formed in a position of passing through a crossing point 12. By rolling a circular cone top 16 rotated with the center of the disk pan 13 serving as the center, circular motion is performed while putting the cone top in press-contact with the tube 1. In this way, a pulsating flow generated by converting a tube internal pressure from reduction to increase with the crossing point 12 of the tube 1 bordering can be eliminated by overlapping the tube crossing point 12.

Title: Precision phase adjuster of light wave by air temperature control
Inventor: HIRANO HAGUMU
IPC: G02F1/01
Filed: 1991-11-14
Abstract: PURPOSE:To enable the ultra-precise adjustment of the phase of light waves by precisely adjusting the temp. of an air cell, thereby adjusting the refractive index of air and creating an optical system for multiplying an optical path length therein. CONSTITUTION:Two pieces of mirrors constituting the optical path of a multiple reflection type are fixed into an aluminum cell 2 to form a light incident part and exit part in the cell 2. Plane lenses 3 consisting of glass are used for the light incident part and exit part in order to prevent mixing of the air in the cell 2 and the outside air. A thermister 4 is embedded into aluminum and the resistance change of the thermistor 4 by a temp. change is detected as an electric signal. The temp. of the aluminum is controlled by a Peltier element 5, etc. The passage for the entrance and emission of the external air is formed slender and curvlinear in order to equal the air pressure in the cell 2 and the air pressure of the outside and to prevent the transfer of the heat by convection between the air in the cell 2 and the air of the outside. A clesiccating agent 7 is placed in the passage for the entrance and emission of the external air to remove the moisture of the air flowing in from the outside in the case of drying of the air in the cell to the dry air.

Title: Wh pulse detection circuit
Inventor: HIRANO YUICHI
IPC: G01R19/165
Filed: 1996-12-17
Abstract: PROBLEM TO BE SOLVED: To surely detect pulses while suppressing influence of the change of a feed voltage, by comparing a reference voltage value generated in conformity with the change of a source voltage value supplied from the outside with an input voltage value. SOLUTION: The voltage value of an external pulse detected by a pulse detector 2 is measured by a pulse voltage-measuring part 3, and compared at a comparing part 4 with a reference voltage value (threshold value) set beforehand. The comparing part 4 informs the pulse having the voltage value exceeding the reference voltage value as a detection pulse. At this time, a reference voltage-generating circuit 5 changes voltage values of threshold values Wth H, Wth L in conformity with a change width of a center voltage of a comparing circuit 6. The potential difference of the center voltage and threshold value Wth H, Wth L is kept nearly constant so long as a change width of a source voltage is in a range whereby a Zener voltage is secured.  Since a detection range of pulse detection signals in the comparing circuit 6 is maintained at a constant value, the detection range of pulses to be detected is prevented from being narrowed even when the feed source changes large.

Filed: 1998-11-09
Abstract: PROBLEM TO BE SOLVED: To provide an engine having possibility of denying the second law of the thermodynamics by taking out the power from operating fluid expanded/ contracted by diurnal range of atmosphere. SOLUTION: An outer shell 1 of a tank is made of a metal of small specific heat and a heat radiating board 2 is used for collecting heat in temperature rise. Fluid having small specific heat and a large heat expansion coefficient is used as operating fluid 3. A safety device 4 is left open in installation and in emergency, the device is stopped by opening it. Gears and a power transmission device 7 change the linear movement of a piston 6 into a quicker rotation movement by combining a plate gear with a wheel set type gear. Before sunrise, the operating fluid 3 in a tank is contracted because of the low temperature so that the piston 6 in the cylinder 5 is drawn near to the tank side by the atmospheric pressure.  At dawn and the sunshine, the temperature is raised, the operating fluid 3 in the tank is heated and expanded, the piston 6 is moved, and the power is transmitted from the plate gear to the wheel set type gear. After that, the operating fluid is started to be contracted by the lowering of the temperature so that the piston 6 and the gears 7 are moved inversely.

Title: Air release valve
Inventor: ASADA TETSUO
IPC: F16K24/00
Filed: 1999-12-15
Abstract: PROBLEM TO BE SOLVED: To provide an air release valve having large vacuum break ability and capable of quickly performing vacuum break. SOLUTION: A valve chest 3 with an inflow port 4 and an outflow port 5 opened in a lower part and an upper part, respectively, is formed by a easing constituted of a main body 1 and a cover 2. A valve seat 6 is formed between the valve chest 3 and the outflow port 5. The main body 1 integrally has a plurality of ribs 9 projecting to the inside at an inner wall of the valve chest 3. At the inside of the ribs 9, a float receiver 10 having a bottomed and almost cylindrically shaped through hole 13 of large opening area at a bottom part is fixed. Within the float receiver 10, a spherical float 12 is arranged in a free state. A throttle valve body 14 for changing opening area of the through hole 13, increasing flow from the inside to the outside of the float receiver 10 and restricting flow of an opposite direction is fixed at the outside of the float receiver 10.  Because external air flowing into the float receiver 10 can be passed to the outside of the float receiver 10 by the through hole 13 of large opening area, air seldom springs back by hitting on the bottom part of the float receiver 10 and pressure in the lower part of the float 12 within the float receiver 10 becomes difficult to rise. Therefore, the float 12 becomes difficult to float, vacuum break ability becomes large and vacuum break can be quickly performed.
