Abstract: PURPOSE:To form a film excellent in close adhisiveness with the surface of a metal and having high strength, by coating a metal surface with an epoxy resin having a specific condition as a primer while further coating an epoxy powder paint at the m.p. of said epoxy resin or more. CONSTITUTION:A metal surface is at first coated with an epoxy resin having an epoxy equivalent of 1,000 or less per a molecule and average 1.4 or more of epoxy groups in a thickness of 0.5-5.0mum as a primer. In the next step, under such a state that the metal is heated to the m.p. or more of an epoxy powder paint, the epoxy powder paint is applied to the primer coating surface to be cured. By this method, an epoxy resin film layer excellent in close adhesiveness with the metal surface and high in film strength can be formed.

Abstract: PROBLEM TO BE SOLVED: To change vehicular speed according to a road condition so as to reduce the number of vehicle accidents by transmitting data in relation to control of vehicular speed in an engine controlling data by a transmitter arranged on a road, and controlling an engine on the basis of the data. SOLUTION: When a key switch is turned on for starting an engine, a data 2a changed by an outside of a vehicle in a control data on a ROM 2 is transmitted to a RAM 3. The engine is controlled in compliance with previous engine control by a CPU 1, and control is started by a learning value 1a, a data 2a on the RAM 3, and a basic data 2b on the ROM 2. In the case where a speed control data 5a is received by a transmitter 4 on traveling, a control data 4a received is transferred to the RAM 3, the control data 4a is renewed, and thereby, it is reflected in control of the engine. After the control data 4a is received, comparison with car speed and the existence of decelerating operation are confirmed, and then, speed is decelerated in compliance with the control data 4a.

Title: Tape drive mechanism
Inventor: OKADA HITOSHI
IPC: G11B15/30
Filed: 1992-04-13
Abstract: PURPOSE:To embody low speed and reciprocal running of a tape without damaging the tape in a simple mechanism which does not call for high precision. CONSTITUTION:A reel base 5 is installed to a rotary shaft of a reel motor 3. A gear is installed to the circumferential part of the reel base 5. One end of a gear board 9 is held with a shaft 9a in such a fashion that it may rotate freely. A warm gear 8 and a gear 6, which are designed to transmit the rotation of a motor 8 to the gear on the reel base 5, are installed to the gear board 9. When a solenoid 10 operates and rotates the gear board 9, the gear 6 is engaged with the gear on the reel base 5. Under this state, the motor 8 is reciprocally rotated, thereby forcing the tape to run reciprocally at a lower speed.

Title: Partially stabilized zirconia powder and its production
Inventor: KIMURA NOBUO
IPC: C01G25/02
Filed: 1986-04-21
Abstract: PURPOSE:To obtain the titled power wherein the content of expensive Y2O3 is lowered, having a low-temp. sintering property and excellent thermal deterioration resistance, and useful as the structural material for mechanical parts, a wear-resistant material, a cutting material, etc., by dissolving Y2O3 and TiO2 in ZrO2 in specified ratios. CONSTITUTION:The partially stabilized ZrO2 powder consists essentially of ZrO2, contains 1.0-3.0mol% Y2O3 and 0.5-30mol% TiO2, and is obtained by dissolving Y2O3 and TiO2 into ZrO2. The baking temp. is controlled to >=1,400 deg.C under atmospheric pressure, or usually to >=1,500 deg.C, to obtain the high-density sintered body of the partially stabilized ZrO2. The ZrO2 particle is grown to >=0.5mu at >=1,400 deg.C. Since thermal deterioration is caused at >=3mol% Y2O3, a large amt. of expensive Y2O3 has been necessarily used. When TiO2 is used, TiO2 is dissolved in ZrO2 even in the sintered body, hence the tetragonal structure is stabilized, and expensive Y2O3 can be reduced. The powder is obtained by forming the composite metallic precipitate of Zr, Y, and Zn from a soln. contg. the compds. of the Zr, Y, and Ti, and calcining the precipitate.

Title: Pressure-temperature compensated flow control valve
Inventor: IWABUCHI NOBUHIRO
IPC: F16K17/22
Filed: 1980-07-07
Abstract: PURPOSE: To make it possible to accurately control a distribution flow rate by regulating the change of an opening area in the middle course of temperature variations, in a pressure-temperature compensated flow control valve.  
     CONSTITUTION: The fluid fed to an inflow port 2 flows into a hydraulic chamber 13 and a center hole 11 on a throttle member 10 from an inflow channel 6 via a pressure compensation valve 16 and finally goes out to an orifice 3 after being controlled by a throttle 12. The throttle member 10 expands or contracts by temperature variations of the fluid, changing the opening area and thus varying in the distribution flow rate of fluid. Since the throttle member 10 is provided with a regulating member 14 being less in the coefficient of thermal expansion, the gap H comes into zero whereby when a different diametrical step part and a stopper part of the center hole 11 arrive in contact each other, the amount of the axial part's expansion of the throttle member 10 is thus regulated. As a result, the distribution flow rate varies halfway in temperature variations of its opening area's contraction. Consequently the regulating member 14 is operated forward and backward, adjusting the gap H properly, by which the distribution flow rate is accurately controlled in a wide range of temperature variations.
