Title: Heater controlling device of air conditioner
Inventor: MOCHIDA JIYUNICHI
IPC: F25D21/00
Filed: 1981-06-30
Abstract: PURPOSE:To enable to defrost without imparing comfortability by a method wherein the power supply to a preheater is controlled in proportion to the result of comparison of the integrated power supply time to the preheater and the set power supply time  with the intention to operate the preheater in order to prevent the lowering of blowing off air temperature at the start of defrosting. CONSTITUTION:When the heating operation is started, the signal of a frosting signal generator 1 and the signal of a starting timer 2, which starts to operate after the elapse  of 45min, and inputted to an AND gate 3, resulting in preventing the frosting signal from sending to a discriminator 8b. When the frosting signal is inputted to the discriminator 8b after the elapse of 45min, the integrated power supply time ta, which is the sum of the continuous power supply time of an indoor motor 7 stored in a memory 6 and of the continuous power supply time of the preheater stored in a discriminator 8a, is compared with the set heater power supply time (about 6min) tb. When the time ta is larger than or equal to the time tb, a defrosting controlling circuit 4 is put into operation in order to start defrosting. On the contrary, when the time ta is smaller than the time tb, a preheater energizing circuit 5 is put into operation for the duration of time that the time ta becomes zero value and, after the finish of preheating, the defrosting is started.

Abstract: PROBLEM TO BE SOLVED: To prolong the service life of brakes and improve safety by increasing or decreasing the pressure applied to hydraulic fluid when the displacement member of the hydraulic pressure chamber of a cylinder piston device is activated by an electronic control device to increase or decrease the friction force introduced in a friction member. SOLUTION: The piston of a master brake cylinder 2 is displaced by the operation of a brake pedal 1, and the hydraulic pressure liquid displaced flows into a hydraulic pressure chamber, and the increased hydraulic pressure displaces a brake piston 6b and presses a brake lining 7a against a brake disk 8. The friction force of the brake disk 8 is detected by a sensor 25, and an electronic controller 22 determines the brake magnitude desired by the operator from pedal operating force and speed and convert the brake magnitude into control signals. Through this operation, an actuator 14 moves an operation member 15 to the hydraulic chamber 4, increasing the volume of a displacement member 12 and the pressure in the hydraulic pressure chamber 4, as a result the brake piston 6b is further pressed. During the operation, a two way solenoid valve 23 is closed. Therefore, the service life is prolonged and safety is improved.

A pressure operation is immediately started from the present position when the 2nd motor 35 for pressure is driven via the 2nd gear system. The need for intricate cylinders is eliminated by the above-mentioned method and therefore the mechanism is simplified and the quick pressure is made possible.
