摘要： PROBLEM TO BE SOLVED: To provide a free piston-type stirling cycle engine which is inexpensive, has a small outer diameter as the whole engine and has high efficiency.
SOLUTION: The free piston-type stirling cycle refrigerator as a free piston-type stirling cycle engine comprises a cylinder 7, a piston 18 that can be reciprocated within the cylinder 7, and an electromagnetically driving mechanism 19 as an electromagnetic mechanism that reciprocates the piston 18. The electromagnetically driving mechanism 19 comprises a moving part 20 and a stator 35. The moving part 20 comprises a permanent magnet 24 disposed outside an inner yoke 23 formed of a permeable material. The moving part 20 and the piston 18 are disposed in an axial direction, and the stator 35 and the cylinder 7 are disposed in an axial direction, whereby the outer diameter Rm of the moving part 20 in the electromagnetically driving mechanism 19 can be reduced. Thus, the inner diameter Rs and the outer diameter of the stator 35 provided outside the moving part 20 and, in its turn, the outer diameter of the whole stirling cycle refrigerator can be reduced.

摘要： PROBLEM TO BE SOLVED: To form a device furnished with a vibration absorbing unit in a compact size. SOLUTION: The vibration absorbing unit comprises a casing 1 having a reciprocating piston 3, a first fixing member 5 arranged approximately orthogonal to a vibration direction Y of the device such as the piston 3 or the like, a second fixing member 7 arranged approximately in parallel in a designated interval with the first fixing member 5, one weight 8 arranged between both fixing members 5 and 7 so as to be approximately coaxial with a vibration center of the piston 3, and a coil spring mechanism 12 suspending the weight between both of the fixing members 5 and 7 by installing approximately in parallel to a vibration direction Y of the piston 3. Both of the fixing members 5 and 7, the weight 8, and the coil spring mechanism 12 are arranged in the inside of the casing 1. In harmony with vibration of the reciprocating piston 3, the weight 8 suspended by the coil spring mechanism 12 can absorb vibration transmitted to the casing 1 by resonating with the vibration of the piston 3 in the inside of the casing 1, and the casing 1 can be also miniaturized.

摘要： PROBLEM TO BE SOLVED: To provide a power-saving and low-noise CPU cooling device attaining a high cooling capacity at low costs. SOLUTION: A hollow vaporizer 1 is disposed on the top face of the CPU 60 in a close contact state, and heat from the CPU is absorbed by the heat of vaporization of a refrigerant 5. The refrigerant vapor 5a moves upwards in a vapor passage 4, flows through an inflow section 21a in the upper part of a condenser 2, and is liquefied by dissipating heat. The liquefied refrigerant 5b moves downwards of the condenser 2 due to the weight of itself, flows out from an outflow section 21b, and moves downwards through a liquid passage 3. In this way, the refrigerant is circulated and repeats absorption of heat in the vaporizer 1 and dissipation of heat in the condenser 2.

摘要： PROBLEM TO BE SOLVED: To provide an easily assemblable heat exchanger used for a stirling engine with improved heat exchange efficiency, reduced size, and reduced weight.
SOLUTION: An entrance plate 1, a plurality of middle plates 3 and an exit plate 2 respectively having a ring shape are closely contacting with each other and inserted between a cylindrical outer casing 4 and inner casings 5. The entrance plate 1 and the exit plate 2 have openings 1a etc. and openings 2a etc. at equal pitch interval in circumference direction to be aligned to have a half pitch deviation from each other. The middle plate 3 has openings 3a etc. at a half pitch interval of the the entrance plate 1 to be aligned to fit to every second openings 1a etc. of the entrance plate. Working-fluid flowing from the openings 1a, etc. of the entrance plate is blocked by the exit plate 2, and some portion thereof drifts toward the circumference direction on each middle plate 3. The drift toward the circumference direction increase heat-transfer area to raise heat exchange rate. Further, the drift toward the circumference direction flows out straight through the adjacent openings 1b etc., hence inhibiting increase of pressure loss.

摘要： PROBLEM TO BE SOLVED: To effectively prevent gas leakage between a rod and an through-hole while reducing the manufacturing cost by mitigating the requirement of the concentricity and parallelism between the rod 11 of a free piston 1 and the through-hole 22 in a driving piston 2. SOLUTION: A circumferential groove 23 is provided in the through-hole 22 in the driving piston 2, and the low friction follow-up seal 4 formed by stacking thin-plate disks 41 is incorporated in the circular groove so that, if the concentricity and the parallelism between the rod 11 and the through hole 22 are deviated to some extent, the sealability between the low friction follow-up seal and the outer circumferential surface of the rod 11 can be secured. This constitution can thus mitigate the requirement of the concentricity and the parallelism between the rod 11 and the through-hole 22 to greatly reduce the manufacturing cost while effectively preventing gas leakage.

摘要： PROBLEM TO BE SOLVED: To eliminate the need for suppressing electromagnetic interference and to suppress switching loss in a circuit for converting a DC voltage, for driving a vibration linear motor with a controllable amplitude to a controllable, variable amplitude AC voltage. SOLUTION: When a pair N1 and P1 is turned on, a voltage which approaches V+ is applied to a motor terminal A and a motor terminal B essentially becomes ground potential, so that a motor current IM increases in the indicated direction until the pair is turned off. A non-zero IM is maintained for a period after the pair is turned off. In the meantime, the motor current IM is attenuated to zero via diodes D3 and D1. When a pair N2 and P2 is turned on, a voltage which approaches V+ appears at the motor terminal A, the terminal B essentially becomes ground potential, the motor current IM increases in a direction opposite to the arrow in Fig. 1, until the pair is turned off and maintains attenuation for a short period.
