Title: Air conditioning equipment
Inventor: MIKI MASAYOSHI
IPC: F24F11/00
Filed: 1981-12-11
Abstract: PURPOSE:To perform agreeable air conditioning from the start of air conditioning operation by a method wherein set temperature is changed based upon the detected result of the difference between room temperature and the set temperature. CONSTITUTION:Room temperature signals from a room temperature sensor 4 are transmitted through a temperature comparator 5 to compare room temperatures with the set temperature to a room temperature setter 6. When the difference between the initial room temperature (a) and the set temperature (b) exceeds a fixed value (about 5 deg.C), the room temperature setter 6 resets the set temperature (b) to the set temperature (c), which is different from the set temperature (b) by about 2-3 deg.C (higher in case of heating as illustrated in the accompanying figure and lower in case of cooling). When room temperature reaches the OFF point (d) of the set temperature (c), a compressor 7 is turned OFF. The room temperature setter 6 detects the first OFF action of the compressor 7 counting from the start thereof and sets back the set temperature (c) to the original set temperature (b).

Title: Three-phase controlled rectifying system
Inventor: YAMAGISHI MASAAKI
IPC: H02M7/12
Filed: 1993-08-12
Abstract: PURPOSE:To provide a three-phase controlled rectifying system that can reduce reactive current and improve power factor more than in conventional ways where only voltage between phases is used for rectifying. CONSTITUTION:A three-phase bridge rectifier circuit consists of thyristors T1-T6 to which three-phase alternating current from a star-connected three-phase coil is input. The bridge rectifier circuit is provided with an arm, composed of two diodes D1, D2, the middle point of which is connected with the neutral point of the three-phase coil. When any one of the thyristors T1-T6 is energized, phase current is passed through the energized thyristor and one of the two diodes D1, D2. In this state the output voltage of the rectifier circuit is phase voltage. If output voltage is the same, this widens the angle of conduction of thyristors and reduces the higher harmonic contents of output current more than conventional.

Title: Control method for power unit
Inventor: KONOMA YASUO
IPC: B60W10/10
Filed: 1989-08-03
Abstract: PURPOSE:To suppress slip of a friction element and sink the oil temp. of a transmission by changing over the valve operating characteristics to low torque characteristic when the transmission efficiency in a power transmitting mecha nism has sunk. CONSTITUTION:Judgement is made whether the oil temp. TOIL given by an oil temp. sensor 92 is higher than the specified temp. TL. If yes, there is fear of deterioration of sealing material etc. used in an sutomatic transmission AT, and also fear of generating a sink of the oil pressure, so that another judgement shall be made whether the line pressure PL to operate an oil pressure clutch of the transmission AT is lower than the specified pressure PLL. If yes, the operating oil pressure which should provide perfect engagement of the oil pres sure clutch selected currently will drop, so that a slip is generated in this clutch. This might cause wear of the friction surface of the clutch or burnout due to friction heat. Therefore, the engine is changed over into the operation in low torque valve operating characteristic LTVT.

Abstract: PROBLEM TO BE SOLVED: To provide a sheet processing device that controls a stack stop so that twofold bunches of discharged sheets may stack in order on a discharge tray. SOLUTION: When stacked on a discharge tray 246, a twofold bunch Po of discharged sheets is brought into the position where its leading edge butts against a stack stop 252.
