Title: Air-conditioning device with open air cooling function
Inventor: KIMURA TAKASHI
IPC: F24F1/00
Filed: 1990-02-27
Abstract: PURPOSE:To save energy for backup operation and to produce a compressor protecting effect by a method wherein when open air cooling capacity is insufficient, backup operation of a compressor is effected as an air amount regulating mechanism is controlled so that the temperature of mixture air of the open air introduced to the air inlet side of a vaporizer and return air from the indoor side is not reduced to a value lower than a frosting temperature. CONSTITUTION:When a room temperature is higher than a room temperature set value by a value exceeding a differential in a range wherein an open air temperature exceeds a compressor backup operation minimum opening air temperature and is lower than an open air cooling switching opening air temperature, a damper mechanism 9 is brought into a full closed state, a compressor 1 is run, and brought into a compressor backup operation mode wherein all the open air is introduced when open air cooling capacity is insufficient. When an open air temperature is reduced in a compressor backup operating state to a value lower than a backup operation minimum open air temperature, the damper mechanism 9 is stopped at a point where a mixture air temperature attains a value equal to the backup operation minimum open air temperature. Since temperature at the inlet of a vaporizer 8 is not reduced to a value lower than the backup operation minimum open air temperature, there is no fear of the vaporizer being frosted. Since the damper mechanism 9 is kept in an opening position lower than the minimum opening position of the damper mechanism 9 in which cooling operation is effected, an effect to save energy is produced.

IPC: H05B6/12
Filed: 1978-04-18
Abstract: PURPOSE:To protect a thyristor by the operation of an instantaneous interruption detecting circuit against an instantaneous interruption of low-frequency AC source and the like. CONSTITUTION:A resonance inductance 8 is used for a heating coil. The voltage wave form of a low-frequency AC source 1 is detected by an instantaneous interruption detecting circuit 10 through terminals A1 and A2, and a full-waved rectification wave form is given to the both ends of a resistance 104 through a rectifying circuit.

Title: Driving method for plasma display
Inventor: TANAKA AKIO
IPC: G09G3/288
Filed: 1990-02-27
Abstract: PURPOSE:To evade the erroneous illumination of a cell by making the positive period of a hold pulse applied to a scanning-side electrode shorter than the negative period. CONSTITUTION:Hold pulses are different in duty ratio and, for example, the positive period of the hold pulses is set about 100nsec while the negative period is set about 300nsec and the pulse voltage is set about 180V. Thus, the positive ('1') period of the hold pulses is made shorter than the negative ('0') period. Consequently, the diffusion of electrons and positive charged particles generated by the discharging of a selected cell is suppressed and the time of the positive state of scanning-side electrodes is short, so the occurrence of new discharging is further suppressed by a discharging delay phenomenon. Consequently, the erroneous illumination of the cell when the intervals of cells are short is precluded.
