Title: Method of controlling operation of air conditioner
Inventor: KOGURE HIROSHI
IPC: F04B49/06
Filed: 1987-09-16
Abstract: PURPOSE:To improve the comfortableness due to reduction in the number of times of energy- saving operations and intermittent operations, and reduction in the temperature fluctuation width by forcibly causing the apparatus to carry out a control to operate at the lowest power at the initial time of operation so that a time where the apparatus operates at the lowest power, in a method of controlling the operation of a compressor after the operation of the compressor is stopped by a thermostat. CONSTITUTION:At the initial time of operation, a preliminary operation is carried out for about 2 to 3 minutes. This preliminary operation is carried out for conducting complete oil feeding to respective parts of a compressor normally at an operational speed of about 3000rpm. As a method of controlling the operation thereafter, whether the preliminary operation is an operation after when a difference in temperature between that of the room temperature sensor and a room temperature set value becomes small, or an operation at the time of starting the operation of the air conditioner after once stopping the same, is determined, for example, by the difference in temperature between the value obtained by the room temperature sensor and the room temperature set value. When the temperature difference is large the rotational speed of the compressor varies in proportion to the temperature difference. On the other hand, when the temperature difference is small, the compressor is operated at the minimum rotational speed and stopped and the operation thereof is one after the room temperature has been raised. Upon this time, the compressor is operated at the minimum rotational speed for 3 to 5 minutes. Then, an operation is started to control the rotational speed of the compressor by the temperature difference between the temperature set by the temperature sensor and the room temperature.

Title: Latent image erasing method for charge holding medium
Inventor: OBATA HIROYUKI
IPC: G03G15/05
Filed: 1988-09-13
Abstract: PURPOSE:To easily and securely erase a latent image on the charge holding medium and to use the medium repeatedly by performing exposure by reverse voltage application. CONSTITUTION:A specific voltage is applied between a photosensitive body 1 and the charge holding medium from a power source 17 to perform the exposure. Consequently, minus charges are trapped and held on the insulating layer 1 of the medium 3. Then the polarity of the power source 17 is inverted and exposure is carried out with a specific exposure pattern to record charges with the opposite polarity on the insulating layer 11. Consequently, the latent image formed by the exposure is canceled and the potential on the insulating layer 11 becomes zero, so that the latent image is erased.
