Title: Air conditioner
Inventor: KAKEHASHI SHINJI
IPC: B60H1/00
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To provide an air conditioner for recognizing an air cooling degree in another passage, in the air conditioner having two passages, and arranging a cooling degree detecting means in one side passage for cost down. SOLUTION: The size relation between first and second air capacity is recognized, and also the difference between them is operated in a step S180b. Successively air temperature Te2 is estimated based on an operation result in the step S180c. For instance, when the first air capacity is more than the second air capacity at an air temperature Te1 of 5 deg.C, the air in a second passage can be cooled more, thereby estimating the temperature Te2 is lower than the temperature Te1. At that time, the temperature Te2 is estimated to be lower than the temperature Te1 with the large difference between the first and second air capacity.

Title: Device for opening and closing flow path
Inventor: TSUJI YOSHIOMI
IPC: F16K7/10
Filed: 1979-05-19
Abstract: PURPOSE: To ensure safety of repair work with Hume pipes and steel pipes by using a simplified device for opening and closing their flow path, which device uses a rubber-lined cloth sack, for opening and closing the flow paths at a desired water level to start and discontinue water discharge in the duct.  
     CONSTITUTION: Air is injected into a rubber-lined cloth sack 1 by starting a blower 9, and then Hume pipe 14 is closed. The blower is stopped by reading a preset pressure with a pressure gauge 6. When the pressure becomes excessive, an air blow-off tank 5 acts as a safety valve. When the water level rises with increase of water in the closed state of the Hume pipe 14, an alarm is produced upon reaching an alarm level 10. Also, when a sack exhaust level 11 is reached, electromagnetic valves 8 and 8" are opened while valves 8' and 8"' are closed, so that air in the sack 1 is automatically exhausted by the action of the blower 9. When an alarm level 12 is reached due to water leakage caused by reduction of the inner pressure of the sack 1, an alarm is produced. At the time of the power stoppage, an alarm is produced by a chargeable battery. At this time, air in the sack 1 can be exhausted with a manual valve 7.

Abstract: PURPOSE:To prevent interference between a driving and a resonance signal, and to stabilize an output voltage by using a signal which synchronized with the self- resonance frequency of an output transformer as a driving signal for a transformer, and imposing pulse width modulation upon the driving signal corresponding to an output voltage or current. CONSTITUTION:As an oscillating circuit 1, a voltage-controlled oscillator (VCO) is employed, a pulse width modulating circuit 2 imposes pulse width modulation upon the output of the circuit 1, and a switching element 3 is driven by the output of the circuit 2, thereby driving a transformer 4 which includes a resonance circuit of a distributed capacitance and a coil inductance by the element 3. The resonance responding wave of an output transformer circuit 5 including the coil 4 is detected by a self-resonance frequency detection coil 7, whose detection signal is applied through a phase detecting circuit 8 to the circuit 1, synchronizing a driving signal with a self-resonance frequency. Further, a difference between a signal which responds to the output voltage or current of the circuit 5 and a reference value is detected by a voltage error amplifying circuit 6, and the output of the circuit 6 is applied to the circuit 2 to impose pulse width modulation upon the driving signal, thus stabilizing an output voltage.
