摘要:
A power unit for a vehicle, such as an automobile, includes an internal combustion engine 1 as a prime mover for the vehicle, a generator 3, and a Stirling engine 4 for driving the generator 3. The Stirling engine 4 uses the exhaust gas discharged by the internal combustion engine 1 as a high-temperature heat source. Power generated by the generator 3 is supplied to an electric motor 2 for driving auxiliary machines 7, 8 and 9, and to a battery 5 for supplying power to the electric motor 2. The engine speed of the Stirling engine 4 is controlled through the control of the load on the generator 3 by a field regulator 15. An optimum engine speed of the Stirling engine 4 is determined such that the brake horsepower of the Stirling engine 4 increases to a maximum or substantially maximum brake horsepower. The fuel consumption of the internal combustion engine 1 as the prime mover that produces waste heat as a high-temperature heat source for the Stirling engine 4 is reduced, and the auxiliary machines are driven so as to fully exercise their functions even in a state where the brake horsepower of the Stirling engine 4 is low.

A multistage Stirling engine 1 mounted on an automobile provided with an internal combustion engine has two cylinders 4 and 5. Displacer pistons 6 and 7 and power pistons 8 and 9 are slidably fitted in the two cylinders 4 and 5, respectively. The exhaust gas discharged from the internal combustion engine and serving as a heating fluid flows sequentially through the cylinders 4 and 5 to heat helium gas serving as a working fluid of the Stirling engine. The cylinders 4 and 5 are disposed parallel to each other. Heaters 16 and 17, regenerative heat exchangers 18 and 19, and coolers 20 and 21 are installed between the cylinders 4 and 5. The multistage Stirling engine is flat and compact.

Specification data including a method of measuring the dimension and mask design data for a photomask pattern is transmitted from an order-sender computer via a communication line. An element dimension calculating unit generates a measurement recipe according to the dimension-measurement method and the mask design data to transmit the measurement recipe to an element dimension measuring unit. The element dimension calculating unit calculates production error data of the pattern according to measurement data and the mask design data to transmit the error data to the order-sender via the communication line.

An exhaust heat recovery apparatus includes a joining section extending from a downstream end portion of a second flow passage section to a first flow passage section. The joining section has a communication port formed proximate a valve shaft for directing an exhaust gas from the second flow passage section into a housing section. A valve includes a first valve body supported by the valve shaft for closing a downstream end portion of the first flow passage section, and a second valve body extending from the first valve body for closing the communication port. The first valve body and the second valve body are disposed circumferentially of the valve shaft. The second valve body has an arc-shape having a center provided by the valve shaft.

There is provided a multi-cylinder engine having an intake manifold that includes a plurality of induction pipes which are each connected at, one end thereof, to a cylinder head the induction pipes extending away from the cylinder head and being curved to extend along a side of a cylinder block, and thereafter being curved further to approach the cylinder block to finally extend toward the respective one end sides of the induction pipes. In the multi-cylinder engine, a starter motor is disposed in a gap defined between the intake manifold and the cylinder block.

An aperture used in an optical device includes a first light-transmitting region which transmits light emitted from a light source which is provided in the optical device, and a second light-transmitting region which is provided in the periphery of the first light-transmitting region and provides light passing therethrough with a phase difference of 180° with respect to light passing through the first light-transmitting region. Thus, improvement in a function which is required for the optical device can be achieved.

A method of selecting a photomask manufacturer includes the steps of storing bidding data sent from a photomask manufacturer, correcting a responded delivery date included in the received bidding data to a corrected delivery date based on a delivery date achieving ratio in a last month, storing priorities relating to a delivery date, technology, order reception and price, reading the corrected delivery date for each of the manufacturers making a bid for a product number to be ordered when the product number is input, calculating total evaluation for each photomask manufacturer based on the plurality of priorities, and selecting the photomask manufacturer satisfying the corrected delivery date and providing the highest result of total evaluation, as the receiver of the order.
