Disclosed is a refrigerator which comprises a plurality of reciprocating motion type expansion engines, a converter mechanism, a speed-up mechanism, and a energy converting mechanism. The engines and the three mechanisms are assembled solidly so that they are successively direct-coupled in a main direction substantially parallel to a direction in which pistons of the engines reciprocate. The converter mechanism converts reciprocating motion of the pistons into rotation by means of a cylindrical cam with an output shaft extending along the main direction, the speed-up mechanism increases the rotation speed of the cylindrical cam and rotates the output shaft at high speed, and the energy converting mechanism includes a generator section having a rotor direct-coupled to the output shaft, electric power generated at the generator section being consumed by an electric load located in a suitable position when the rotor is rotated at high speed.

A speed-deceleration warning system for motor vehicles comprising pressured-oil supply means connected to a master cylinder of a brake mechanism, a hydraulic switch including a first contact moved by the action of pressured-oil, a speed-deceleration switch including a second contact moved by the influence of speed reduction of a vehicle and an electric circuit extending to a warning element through said first and second contacts. Such a device is applied for sending a warning to a driver if speed-deceleration of a vehicle does not reach an expected value although brake means are set on and hydraulic brake pressure rises over a prescribed value.

To prevent, in a resin-sealed type semiconductor package, generation of cracks in a die bonding material used for mounting of a semiconductor chip. A semiconductor chip is mounted over the upper surface of a die pad via a die bonding material, followed by sealing with an insulating resin. The top surface of the die pad to be brought into contact with the insulating resin is surface-roughened, while the bottom surface of the die pad and an outer lead portion are not surface-roughened.

An acoustic wave resonator includes a piezoelectric body, an IDT electrode for exciting an acoustic wave with wavelength λ, and a dielectric thin film provided so as to cover the IDT electrode. The IDT electrode includes a bus bar electrode region, a dummy electrode region, and an IDT cross region in order from outside. The film thickness of the dielectric thin film above at least one of the bus bar electrode region and the dummy electrode region is smaller than that above the IDT cross region by 0.1λ to 0.25λ. This configuration provides an acoustic wave resonator that reduces transverse-mode spurious emission.

A combustion air supply apparatus 9 of alternating heat exchange type supplies combustion air and discharges combustion exhaust gas at a flow velocity of 80 to 200 m/sec. A burner assembly 4 is configured in such a manner that low-caloric fuel gas is pre-heated with heat of pre-combusting high-caloric fuel gas before the low-caloric fuel gas reaches a mixing starting space CA in the combustion chamber where the pre-combusting high-caloric fuel gas and the low-caloric fuel gas come to burn together in a full scale in the mixing starting space CA. When an air amount of the combustion air supplied through the high-temperature air supply ports of the plurality of fuel gas combustion apparatuses is defined as Q1 and an air amount of the pre-combustion air to be mixed with the high-caloric fuel gas, supplied from the fuel gas combustion apparatuses, is defined as Q2, a total air amount (Q1+Q2) is 1.02 to 1.10 times more than a theoretical air amount QS required for combustion, and a ratio of Q2/(Q1+Q2) is 0.011 to 0.047.

A driving circuit for causing a light emitting element to emit light in response to a driving signal is provided. The driving circuit comprising a first current supply circuit that starts to supply a driving current to the light emitting element in response to the driving signal, a second current supply circuit that starts to supply a supplementary current to the light emitting element in response to the driving signal. The second current supply circuit stops to supply the supplementary current upon detecting that a voltage applied to the light emitting element has reached a threshold voltage.
