Title: Non-drip gun
Inventor: MIYATA MASAKAZU
IPC: F16K23/00
Filed: 1989-11-25
Abstract: PURPOSE:To prevent oil drops from dripping from the top end of a valve unit by providing a valve unit, having a suction hole, shaft unit 6 and a piston in a main unit, having a delivery port, and a cavity in the shaft unit and connecting the suction hole to a negative pressure suction source to suck the oil drip. CONSTITUTION:A valve unit 4, shaft unit 6 and a piston 7 are formed as an integral unit and slidably fitted into a main unit 2 in which a delivery port 3 is opened to the point end part, and an oil path 10 and an oil reservoir 9 are formed. A suction hole 5, penetrating through in a direction of the axial line, is provided in the valve unit 4, and a cavity 8, communicating with the suction hole, is provided in the shaft unit 6. The inside of the cavity is connected to a Venturi tube 16 (negative pressure suction source). Since oil drops adhering to the top end part of the valve unit, are sucked by negative pressure suction force generated in the cavity, fluid is prevented from dripping after the delivery port is cut off.

Title: Wheel lock preventing device
Inventor: KUROMITSU HIROSHI
IPC: B60T8/48
Filed: 1986-12-22
Abstract: PURPOSE:To prevent a driver from feeling unpleasant, by a method wherein a power- liquid pressure feed source and a regulator valve are situated, an opening closing switching valve is located in a brake liquid pressure circuit, and a brake liquid pressure is introduced through a check valve to a brake liquid pressure circuit situated between the opening closing switching valve and a feed discharge switching valve. CONSTITUTION:Under an antiskid working state, a regulator valve 60 regulates a liquid pressure, fed from a power liquid pressure feed source 70 based on liquid pressure in a master cylinder 12 or a pressure equivalent thereto, serving as a reference pressure, to a regulator liquid pressure approximately equivalent to a reference value to output it. A liquid pressure (a regulator liquid pressure) from the regulator valve is repeatedly and intermittently fed to a wheel cylinder through the switching action of feed discharge switching valves 31, 33, and 35, where occasion demands. Therefore, although a regulator liquid pressure itself is sometimes fluctuated, since the regulator liquid pressure is not used for assisting working of the master cylinder 12, a fluctuation in working of the master cylinder is prevented from occurring due to a fluctuation in the regulator liquid pressure and a driver is prevented from feeling unpleasant due to pedal vibration.

Title: Thermoelectric converter
Inventor: YAMADA AKIRA
IPC: H02N3/00
Filed: 1987-12-03
Abstract: PURPOSE:To improve the efficiency of thermoelectric conversion by feeding inert gas at a high temperature. CONSTITUTION:Na<+> ions flow into beta-alumina 23 due to sodium vapor pressure difference at both ends of the alumina 23. When an external circuit is closed, the Na<+> ions obtain electrons on the face of a porous electrode 24 to be neutralized, and deposited in a low temperature vessel 21, thereby generating electric power. On the other hand, when the external circuit is opened, charge is concentrated on the face of the electrode 24, an electric field is generated in a direction of stopping the flow of the Na<+> ions, thereby generating an opening voltage. The Na vapor evaporated in the vessel 21 is liquefied on a condensing face, the liquid Na 22 is again continuously supplied by a pump 26 to a high temperature side, thereby continuing its generation. The pump 26, an Na condenser 28, a gas blower 31 and a regeneration heat exchanger 33, etc., are provided, inert gas, such as argon at a high temperature is fed into the atmosphere, thereby reducing the partial pressure of the Na vapor pressure. Since the outer periphery of the electrode 24 is not necessarily cooled, heat loss due to radiation heat is substantially eliminated.

Abstract: PURPOSE:To improve characteristic by incorporating piezoelectric porcelain powder in an organic group material, applying pressure in the thickness direction to vulcanize and mold specific piezoelectric composite material in a flat plate shape, then polarizing it in a pressure application direction, and arranging electrodes on the front and rear surfaces. CONSTITUTION:Piezoelectric porcelain powder is incorporated at 65% or higher in organic group material, pressure is applied in a thickness direction to piezoelectric composite material so formed with pores that relative density (percentage of actually measured density Pmeas to theoretical density Pcal) becomes 93.0097.00% to vulcanize to mold it in a flat plate shape, to then polarize it in a pressure application direction, and electrodes are arranged on front and rear surfaces. Accordingly, the powder is continued densely in the thickness direction, but air layers are radially interposed in the continuous powder of thickness direction. Thus, excellent conversion efficiency is obtained for vibration of thickness direction, the value of piezoelectric constant is improved. On the other hand, air layers radially become buffer layers to alleviate radial vibration, and the absolute value of the piezoelectric constant is reduced.

Title: Optical recording medium
Inventor: KOBAYASHI YOSHIMITSU
IPC: G11B7/2437
Filed: 1986-12-23
Abstract: PURPOSE:To permit recording with not only high sensitivity but high quality as well by specifying the ratio of C and F and ratio of CF2 and CF3 in a fluorocarbon under coating layer on a substrare. CONSTITUTION:The under coating layer consisting of a sputtered film or plasma-polymerized film of fluorocarbon is formed on the substrate. C/F of the lower layer of the fluorocarbon is specified to 0.9-1.8 and further, >=18% of the total carbon atoms is required to constitute a -CF3 group and 18-40% to constitute a -CF2 group. The fluorocarbon under coating layer having such structure has not only the high sensitivity but permits the recording with high quality as well. The sensitivity is poor if the conent of the CF2 group is low. Pit shapes are too large and such are not adequate for high-density recording if said content is too high. The residue remains in the pits and is detected as noise if the content of the CF3 group is low. The C/N is, therefore, low.
