    Abstract: PROBLEM TO BE SOLVED: To effectively rotate an agitating blade in a cavity of a manifold body by providing an agitating member in the cavity, and rotating the member by a motor having a rotor in the body and a stator externally mounted on the body. SOLUTION: In the manifold 1 containing a thermoelectric module 7 having a Peltier effect for performing a cooling action, when energizing to start operating of a cooler, a temperature of a heat transfer surface of a heating side of the module 7 is raised, and a temperature of a heat transfer surface of a cooling side is lowered. A stator 8 formed as a part of a motor is excited, and a rotor 16 contained therein through a heating side manifold 2 is rotated. As a result, a heating side agitating member 5 integral with the rotor 16 is rotated, a heating medium in each cavity is agitated by rotation of the blade 15, and the medium given by the energy by the module 7 is discharged externally from outlets 14, 24.

    Abstract: PROBLEM TO BE SOLVED: To simplify manufacture of a circular thermoelectric module while facilitating formation of multistage structure by sandwiching a rectangular thermoelectric module bonded with a plurality of Peltier elements arranged squarely between discs. SOLUTION: A circular thermoelectric module 10 comprises a rectangular thermoelectric module 11 sandwiched between discs 12, 13. The thermoelectric module 11 employs a known Peltier element wherein P type semiconductors and N type semiconductors are arranged side by side. The thermoelectric modules 11 are connected in series through upper and lower alternating electrodes and secured vertically by means of a ceramic insulating board. A set of P type and N type thermoelectric semiconductors constitutes a minimum unit of Peltier element. Solder is used frequently for bonding each thermoelectric semiconductor and the electrode. A known adhesive is used for bonding the disc 12, 13 and the thermoelectric module 11.

    Abstract: PROBLEM TO BE SOLVED: To lower starting torque in a starting time by providing a controller always opening a discharge valve in a starting time. SOLUTION: A tip part 20a of an electromagnet 20 is opposed to a discharge lead 7 via a spring lead 22 and a stopper 23 so as to be fixed in a cylinder head 15. In a starting time, a compressor start detecting means detects a start, of a compressor so as to give an excitation command for a timer which energizes the electromagnet 20 for a set time set around a time required for bringing the compressor to the steady number of revolutions. Then, the electromagnet 20 is magnetized by means of excitation based on the timer, and by means of the magnetic force from the tip part 20a, the discharge lead 7 is forcibly opened, and then, a discharge valve 5 is set in a normally-open condition. Under this condition, coolant is hardly compressed even if a piston 3 is advanced and set in a compression stroke. After a lapse of the set time, the timer stops excitation to the electromagnet 20 so as to release magnetization in the electromagnet 20, so that the discharge valve 5 is returned to a normal condition.

    Abstract: PROBLEM TO BE SOLVED: To control capability of a compressor by adjusting opening of a suction valve during operation of a compressor, and controlling a circulation amount of coolant. SOLUTION: A compressor is provided with a suction valve 11 which has a suction lead 14 in which a magnet 20 is fixed to a surface corresponding to a suction hole 12; an electromagnet 21 which has a leading end directed to the suction lead 14 at the position opposed to the suction lead 14 through the suction hole 12 and the suction hole 12; and an under-operation current carrying voltage control device which carries current to the electromagnet 21 during operation and adjusts the voltage. It is thus possible to adjust lifting up of the suction lead 14 and control a passage amount of coolant.

    Abstract: PURPOSE: To enable the liquid compression diagnosis of a compressor without needing any prototype by envelope detection of a piezo-electric signal from a piezo-electric element mounted on the external appearance part of the compressor. CONSTITUTION: A sensor 2 consisting of a piezo-electric element mounted on a compressor 1 detects a signal caused by the liquid compression of the compressor 1, and the detected signal is subjected to envelope detection by an envelope detection apparatus 3 and indicated on an output apparatus 4. Then, the outputted signal has the same wave form as the actual pressure waveform in timing and form of the peak waveform. Thus, a liquid compression phenomenon can be judged from a threshold line corresponding to the highest pressure line in the normal running and the liquid compression can be confirmed when a peak value of the signal peak waveform exceeds the threshold line.
