IPC: C22C37/00
Filed: 1987-12-21
Abstract: PURPOSE:To produce a cast iron product for a vacuum vessel effective in keeping the degree of vacuum of a high vacuum atmosphere by coating the inside of a casting mold with a graphite spheroidizing agent and pouring molten cast iron to spheroidize graphite only in the surface layer of the resulting casting. CONSTITUTION:A frame 8 is placed on a suction box 5 provided with a filter 5a and a suction hole 5b and a material 7 for a casting mold is filled into the frame 8 so as to leave a cavity 6. This cavity 6 is lined with a graphite spheroidizing agent (Fe-Si-Mg powder) mixed with a binder to form a coating layer 6a. Molten cast iron 10 is then poured into the cavity 6 from a sprue and gas generated by a reaction is exhausted by suction from the suction hole 5b. A casting contg. spheroidized graphite only in the surface layer is obtd. and the outside of the casting is plated as required.

Title: Cooling and heating device
Inventor: HIROSE KENJI
IPC: F24F11/02
Filed: 1990-11-26
Abstract: PURPOSE:To restrict liquid refrigerant from flowing into a refrigerant pump by a method wherein a pressure difference between an inlet port and an outlet port of a refrigerant pump is detected and the third solenoid valve is controlled under a cooling operation and the second solenoid valve is controlled under a heating operation. CONSTITUTION:A control device 18 calculates a pressure difference between detected values of pressure sensors 16 and 17 disposed at an inlet port and an outlet port of a refrigerant pump 10 and controls the first to fourth solenoid valves 11, 12, 13 and 14. As the pump 10 starts to compress liquid, the pressure difference between the inlet port and the outlet port is rapidly increased. For example, during a cooling operation, and if the pump 10 compresses liquid, the solenoid valve 11 is opened, the solenoid valve 13 is opened or closed repeatedly and then the solenoid valve 12 and the solenoid valve 14 are closed. Refrigerant flow passes from the pump 10 through the solenoid valve 11 and the second auxiliary heat exchanger 7 and reaches the solenoid valve 13. The solenoid valve 13 repeats the opening or closing operation, so that the large amount of liquid is hardly flowed in. During a heating operation, a flow of refrigerant is reversed and the device 18 controls the solenoid valve 13 during a cooling operation and in turn during a heating operation it controls the solenoid valve 12, thereby it is possible to restrict the liquid refrigerant flowing into the pump 10.

IPC: B62D6/00
Filed: 1999-11-16
Abstract: PROBLEM TO BE SOLVED: To permit precise automatic parking by preventing the discrepancy of a moving locus while minimizing time required for automatic parking. SOLUTION: This automatic steering system for a vehicle steers front wheels by a steering actuator on the basis of a moving locus previously stored as the relation of a normative steering angle θ ref of a steering wheel to the moving distance X of the vehicle. In this constitution, when the inclination of a moving locus line is made Δθref/ΔX, and the maximum steering angle speed determined by the performance of the steering actuator is made αmax, the limit vehicle speed Vlim during automatic steering control is set by Vlim (ΔX/Δθref).αmax. This can prevent the discrepancy of the moving locus generated by the actuation delay of the steering actuator 7 caused by the overspeed of the vehicle.

Title: Method of surface treatment for blade-stabilized projectile
Inventor: NUMA MASAMI
IPC: F42B12/10
Filed: 1990-11-29
Abstract: PURPOSE:To reduce the number of spin of a blade-stabilized projectile by a method wherein a metal is applied on the surface of the annular groove of the projectile through flame spray coating to form a porous spray coating metallic layer on a contacting surface with an obturator, in the blade-stabilized projectile, in which the obturator is fitted into the annular groove formed on the outer peripheral surface of the projectile. CONSTITUTION:In a blade-stabilized projectile, in which an obturator 3 for preventing the leakage of gas upon firing is fitted into an annular groove 5a formed on the outer peripheral surface of the projectile 5, a metal is applied on the surface of the annular groove 5a through flame spray coating to form a porous spray coating metallic layer 5b on a contact surface with the obturator 3. The friction coefficient of the obturator 3 is reduced remarkably due to the porous surface of the spray coating metallic layer 5b. According to this method, even when the obturator 3 is turned by a rifle on the inner surface of a gun upon firing the projectile out of the gun, relative slip is generated between the obturator 3 and the contact surface of the projectile and the rotation of the projectile is reduced whereby the number of spin of the blade-stabilized projectile can be reduced.
