Title: Controlling device for defrosting of air conditioner
Inventor: MIYAJIMA FUMIO
IPC: F24F11/02
Filed: 1990-07-09
Abstract: PURPOSE:To perform proper defrosting operation and to realize comfortable air conditioning without reducing a room temperature by a method wherein the more a hot air discharge starting time after completion of defrosting is longer, and the more a temperature difference between the detecting temperature of a room temperature sensor and the set temperature of a room temperature setter is increased, the more a heating operation time is decreased. CONSTITUTION:A temperature difference detecting device 7 detects a temperature difference between the detecting temperature of a room temperature sensor 5 and the set temperature of a room temperature setter 6. An air conditioning control device 12 sets a heating operation time based on the detecting result of the temperature difference detecting device 7 and the detecting result of a hot air discharge time detecting device 9, and when the detecting time of an operation time integrating device 8 attains a preset heating operation time, defrosting operation of an air conditioner is started. In an air conditioning control device 12, the more a hot air discharge starting time after completion of defrosting is longer and the more a temperature difference between the detecting temperature of the room temperature sensor 5 and the set temperature of an indoor temperature setter 6 is higher, the more a heating operation time is set to a lower value, whereby proper defrosting operation is performed. When proper defrosting operation is effected, defrosting is decreased, deficiency in capacity due to frosting and the increase of a defrosting time are prevented from occurring, and a room temperature can be prevented from lowering.

Title: Video projector
Inventor: KONDO SATORU
IPC: B21B37/38
Filed: 1990-07-09
Abstract: PURPOSE:To decrease corrected amounts due to a sub-yoke, and to save power by decreasing the distortions resulted from an optical system due to the linearity distortion generated originally at a horizontal deflection part by using an opposite polar connection. CONSTITUTION:This video projector is constructed by three CRT projecting tubes 1R, 1G, and 1B which are arranged in one row for RGB. The linearity correction of the horizontal deflection part of the central CRT projecting tube 1G is operated, and the linearity correction of both the horizontal deflection part of the one end CRT projecting tube 1R and the horizontal deflection part of the other end CRT projecting tube 1B is not operated. Also, the deflection coil 7B of the other end CRT projecting tube 1B is connected by the opposite polarity with the deflection coils 7R and 7G of the other CRT projecting tubes 1G and 1R. That is, when a picture is projected on a screen 2, the distortions of the deflection circuits of both the CRT projecting tube 1R for R and the CRT projecting tube 1B for B is distorted in a direction which erases an extension or a shrinkage due to the optical system, so that the picture can be projected. Thus, the loss of the power for the deflections can be reduced so that power can be saved.
