Title: Ceiling embedded type air conditioner
Inventor: SATOUCHI TAKAYUKI
IPC: F24F1/0007
Filed: 1983-11-02
Abstract: PURPOSE:To shorten defrosting time by a method wherein an auxiliary fan is operated to discharge cool air into only a space at the rear side of a ceiling instead of stopping a fan, upon defrosting operation during room heating. CONSTITUTION:Upon defrosting operation, the fan 8 is stopped, a damper 15 is opened about a hinge 14 and a ventilating path, in which air is flowed by the auxiliary fan 12 from a room 2 to be air-conditioned into the space 3 at the rear side of the ceiling through an air path 7b, heat exchangers 9a, 9b and openings 11a, 11b, is formed. Upon the defrosting operation during room heating, the heat exchangers 9a, 9b become eveporatos and cool air, passes through the heat exchangers 9a, 9b, is discharged into the space 3 at the rear side of the ceiling. Accordingly, the defrosting time is shortened during the defrost operation due to the heat absorption in the heat exchangers 9a, 9b and discharging of cool air into the room 2 to be air-conditioned may be prevented. The ventilating amount of the auxiliary fan 12 is small, therefore, induction of atmosphere into the room 2 to be air-conditioned is reduced and reduction of room temperature may be reduced.

Abstract: PURPOSE:To conserve energy and to economically construct an apparatus, by always measuring the dew point of dry air by a dew point sensor and simultaneously performing the dehumidification of compressed air in all of plural adsorbing towers for a considerable period at the point of time when the dew point was fallen to a first predetermined one. CONSTITUTION:Left and right adsorbing towers 1, 11 according to a cycle system are alternately operated and, when the dew point of dry air at a dry air outlet 20 reached a first predetermined dew point (e.g., -60 deg.C), the left and right adsorbing towers 1, 11 are allowed to simultaneously perform the dehymidification of air on the basis of the signal from a dew point sensor 10 always measuring the dew point of the aforementioned dry air. Subsequently, when the dew point of dry air reached a second predetermined dew point (e.g., -40 deg.C), both adsorbing towers 1, 11 are returned to the cyclic system by the signal of the aforementioned sensor 10. Further, when the dew point of dry air reached the aforementioned first dew point, the left and right adsorbing towers 1, 11 are allowed to again simultaneously perform the dehumidification of air. As a result, energy is conserved and an apparatus can be economically constructed.

Title: Picture forming device
Inventor: YAGASAKI TOSHIAKI
IPC: H04N1/387
Filed: 1983-11-02
Abstract: PURPOSE:To obtain easy-to-see copy by discriminating a read character string at each row and arranging a print start position of the character string to a prescribed position to arange the character start position of the character string where the character start position is irregular such as manuscript characters. CONSTITUTION:A picture data read from a line sensor is stored once in a temporary memory and subject to discrimination of binary coding at a comparator. When all data of one picture element row are discriminated as white level, a counter is counted up, and when a count value shows a prescribed value, it is discriminated as between character rows, an inter-row detecting signal is generated to reset the counter. When a black background signal is detected while the white level signal is counted, the white level signal is discriminated as a part of the character signal and a control signal to control the charactor start position of the next black level signal is fed to a shifter control section. Thus, the print start position of the character string is shifted and arranged always to a prescribed position.

Title: Rotation control device
Inventor: KURIBAYASHI SADATOMO
IPC: F16H9/12
Filed: 1986-09-02
Abstract: PURPOSE:To maintain the rotating speed of auxiliaries of an automobile engine within a fixed range and thereby moderate the operational condition, by providing a rotation control device for increasing the speed of a drive shaft of the auxiliaries during low speed rotation of an output shaft of the engine while reducing the speed of the drive shaft during high speed rotation of the output shaft. CONSTITUTION:During low speed rotation of an engine, an effective radius of a belt 7 wrapped around a continuously variable pulley 15 on an engine output shaft 11 is made large by the operation of a spring 16, while the effective radius of the belt 7 wrapped around a continuously variable pulley 1 on a drive shaft 13 is made small such that the latter is set to be about 1/3 of the former. Accordingly, the speed of the drive shaft 13 as well as the continuously variable pulley 1 is increased. On the other hand, when the engine speed is increased, the width of a V-shaped groove of the continuously variable pulley 1 on the drive shaft 13 is reduced by a centrifugal force of a steel ball 4 to thereby urge the belt 7 toward the outer circumference of the pulley 1 and increase the effective radius. On the contrary, the effective radius on the continuously variable pulley 15 side of the engine output shaft 11 is reduced. As a result, the speed of the drive shaft 13 is reduced.

Title: Supporting mechanism of electric-car line for magnetic levitation-method railway
Inventor: MIHASHI YASUHIRO
IPC: B60L5/08
Filed: 1996-08-06
Abstract: PROBLEM TO BE SOLVED: To increase the current collecting performance of an electric-car line and a current collecting equipment and remarkably lessen the number of working processes by supporting the electric-car line by cross ties which support a rail. SOLUTION: An electric-car line 1 is insulated by a supporting metal fitting 9 including an insulator and is then assembled in a pair of brackets 10 by bolts 11 and then is fastened to cross ties 8 by bolts 12. The brackets 10 which form a pair are so assembled by bolts 13 that they may be symmetrical about a point. Each of the brackets 10 is so structured that a nearly triangular rib is pasted to an L-shaped steel plate along the central line of the plate and a circular hole and an oval hole are made in a flat section of the steel plate partitioned by the rib. The oval hole is longer than the circular one by the amount enough to allow the electric-car line 1 to be installed corrugated.  Owing to this structure, even if an electric car is transversely inclined between a beam and the cross ties, the electric-car line 1 can cope with the transverse inclination of the electric car without the increase in the number of components.
