An absorption refrigerator which is capable of effectively using energy without a necessity of enlarging the size thereof, the absorption refrigerator having a structure that a cylindrical wall is provided for an inner wall portion raised because of a stepped portion of the bottom surface of a double-tube unit so that a refrigerant retainer for accumulating water allowed to downwards flow along the outer surface of a cold-water tube is formed. A refrigerant-circulating passage is connected to the bottom surface of the refrigerant retainer. Another end of the refrigerant-circulating passage is connected to a refrigerant supply passage. When a pump is operated, water in the refrigerant retainer is supplied to a water-receiving pan so as to again be sprayed to the outer surface of the cold-water tube.

A level conversion circuit of the present invention is connected between a first and a second device respectively operable with a first and a second power source voltage different from each other. A first wave shaping element shapes the waveform of a signal output from the output of the first device. A waveform transferring element transfers a signal output from the first wave shaping element to the second device. A level determining element controls the level of a signal to be input to the second device. A second wave shaping element shapes the waveform of a signal having a level determined by the level determining element. With this configuration, the circuit is capable of transferring a waveform from the first device to the second device rapidly and thereby protecting the devices from damage.

An adjustment device adapted to glasses each including two polarization filters having adjustable transmission axes varying an angle therebetween in a front view is constituted of a physical parameter receiving unit for receiving at least one physical parameter which is produced by measuring the user's body, an angle calculation unit for calculating a target angle to be formed between the transmission axes of the polarization filters based on the received physical parameter, and a polarization filter adjustment unit for rotating at least one of the polarization filters, thus making the present angle formed between the transmission axes of the polarization filters agree with the target angle. Thus, it is possible to reduce a load or strain imparted to a user's eyes in light of the user's fatigued condition.

A PLL circuit comprises a circuit which issues an alarm when fluctuation of the potential of a DC power source connected to the PLL circuit exceeds a predefined range. A first potential generation circuit generates a first potential higher than a steady-state potential of the DC power source. A second potential generation circuit generates a second potential lower than the steady-state potential of the DC power source. A first comparator circuit compares a local maximum potential of the DC power source with the first potential. A second comparator circuit compares a local minimum potential of the DC power source with the second potential. A supply circuit supplies a drive voltage to an alarm issuer, in a case where the local maximum potential is higher than the first potential, and/or the local minimum potential is lower than the second potential, based on the comparison results.

A diode circuit of the present invention comprise an input/output terminal connected to the transmission line, a power supply terminal connected to the power supply, a plurality of diodes connected in series between the input/output terminal and the power supply terminal and a capacitive element having one end connected to a connected point of the plurality of diodes and the other end connected to the ground. In the input/output terminal, an applied signal from the transmission line exceeds the predetermined potential, it is clamped to the predetermined potential by the plurality of diodes connected in series. At the connecting points among a plurality of diodes and the input/output terminal, vibration of potential is reduced by the capacitance element.
