Title: Optical switching circuit and optical modulating circuit
Inventor: TAKARA HIDEHIKO
IPC: H04B10/61
Filed: 1998-02-23
Abstract: PROBLEM TO BE SOLVED: To realize a very high speed fully optical switching circuit and an optical modulating circuit with a stable operation against external vibrations by reducing the influence of Sagnac effect. SOLUTION: A polarization holding type photocoupler 1 inputs linear polarized input signal light at one of two input ports and separates it to two output ports in 1:1 proportion. A polarized light composing means inputs the two input light signals separated by a photocoupler 2, multiplexes the polarized waves so that the respective polarized waves match the two main axial directions of an optical Kerr medium, and guides them to the polarization holding type optical Kerr medium. The polarization holding type photocoupler 1 inputs linear polarized control light and multiplexes it with the input signal light so that it matches one main axis of the optical Kerr medium. A polarized light rotary mirror 8 reflects the polarized waves of the input signal passed through the optical Kerr medium and the control light by 90 deg. rotation and reinputs them to the optical Kerr medium.  An optical demeultiplexer 4 separates the control light from the input signal light and control light which are reflected by the polarized wave rotary mirror 8 and go back and forth in the optical Kerr medium.

Abstract: PURPOSE: To perform effective utilization of energy of the drive source of a compressor even when a radiation amount of a condenser is increased to an excessive value compared with a heat absorbing amount of a vaporizer by a method wherein a heat feed part on the indoor machine side and a heat feed part on the outdoor machine side are provided and heat is fed to a refrigerant from the heat feed part on the outdoor machine side. CONSTITUTION: Since, during heating operation, three-way valve A allows the flow of cooling water to a direction 2, a flow rate q1 of cooling water is fed through a cooling water line 4e to a double pipe heat-exchanger 11 and a quantity ΔQ is exerted on a refrigerant flowing therethrough. In which case, the refrigerant is heated by a quantity of ΔQ and all is vaporized for gasification and further, overheating thereof is effected. In this case, the refrigerant flows through a double pipe heat-exchanger 11 to a four-way valve 5. The refrigerant flows through a four-way valve 5 to a suction line 3b side and guided to an accumulator 6. Gas and liquid of the refrigerant are separated by the accumulator 6 and a gas phase refrigerant is sucked to a compressor 2.  This constitution with a compressor left driven, cooling or heating operation is practicable and energy of the drive source of the compressor is effectively utilized.

IPC: G06F15/02
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To prevent the erroneous operation of user by reporting forced suspend processing to the user before its execution. SOLUTION: When the temperature abnormality or low battery of CPU 11 or the like is detected by a power source controller 18, a system power source is turned off after data required for restoring a work environment at that time are saved by a forced suspend processing routine but the system power source is turned off after a message picture is displayed for reporting the forced OFF of system power source because of temperature abnormality. Therefore, the user can recognize suspend due to the thermal runaway prevention or battery exhaustion of CPU 11, when the power source is turned again just after power off due to forced suspend, the erroneous operation of user can be prevented.

Title: Control signal detecting device for facsimile
Inventor: OSHITA KAZUAKI
IPC: H04N1/32
Filed: 1986-02-28
Abstract: PURPOSE:To prevent the deciding of a noise as a control signal by mistake by outputting the same comparing signal as a control signal and multiplying this and an input signal when a locking condition is obtained by using a digital signal processing type PLL circuit. CONSTITUTION:When an input signal including the noise of the same frequency as the procedure interrupting signal of 462Hz enters a PLL circuit 10, the PLL circuit 10 hardly comes to be a locking condition. Even if locking is executed, the locking is instantaneously released at once. When the input signal including the inherent procedure interrupting signal of 462Hz enters the PLL circuit 10, the PLL circuit 10 comes to be the locking condition. Namely, the PLL circuit sends a phase signal to synchronize with the procedure interrupting signal to a SIN wave generator 11. For such a reason, the SIN wave generator 11 generates the SIN wave signal having the completely same procedure interrupting signal, frequency and phase. Consequently, for the multiplying result of both signals, a large peak occurs at a 90 deg. position, this exceeds the threshold and therefore, a slicer 14 outputs '1'. As such a result, it is detected that the procedure interrupting signal comes.

Filed: 1982-03-16
Abstract: PURPOSE:To provide an oil regulator with a two-stage function of pressure control, by fitting disc-like bimetal valves in a valve which acts to control the pressure of oil to a prescribed level. CONSTITUTION:When the pressure of oil in a chamber 13 has gone up, a valve 16 is moved down against a spring 18 to open a passage 21. When the temperature of the oil in the chamber 13 has exceeded a set level, bimetals 24a, 24b are  deformed over so that the bimetal 24a goes off a valve seat 23a. Consequently, a passage 22 is opened so that the oil in the chamber 13 is released through the passage and a drain port 15. As a result, the pressure of the oil in the chamber 13 is controlled to a lower level than that to which the pressure is controlled by the valve 16.
