    摘要: A molding apparatus produces high-density thin type optical disk substrates having good replicability and birefringence sufficient for practical use. In filling the resin into the cavity, the stress on the resin is reduced by controlling the relation of the cavity width and the injection compression force to reduce birefringence. Further, the mirror surface of the mold is maintained at a certain temperature to facilitate the resin flow and a good replicability and reduction of birefringence is achieved by terminating the resin filling and starting the compression process at the time at which the pressure of the resin filling is at a minimum.

    摘要: The inside of the housing is divided into a low pressure fuel area formed from a fuel inflow port through a feed pump 4 and a high pressure fuel area that can communicate with inflow/outflow ports for fuel. For instance, the low pressure fuel area may be formed as a path extending from the fuel intake port that communicates with the circumferential area of the front end of the rotor to the feed pump via the circumferential area of the rotor support member and a passage for inducing fuel from the high pressure fuel area to the circumferential area of the front end of the rotor may be formed between the rotor and its support member. The flow of fuel in the area where the rotor slides in contact with its support member is ensured, and oil film loss is prevented. With this, cooling and good lubrication in the rotor sliding contact area, where heat is likely to be generated, are promoted, to prevent seizure in the sliding contact area. Also, ports that open into the area where the rotor slides in contact with its support member and that communicates with the compression space may be provided in the rotor so that compressed fuel is supplied directly to the sliding contact area.

    摘要: A reduction gear for producing and feeding the rotation of a low pressure turbine driven by a combustion gas generated in a combustor to an output shaft is received in a central opening of a rotary type heat exchanger which is disposed so as to be perpendicular to a turbine shaft at a rear portion of a body housing of a gas turbine engine. As a result, not only the engine can be made small but also the output can be produced at to the opposite side of the heat exchanger. The combustor and a collector housing for collecting combustion gas are disposed on diametrical opposite sides in a transverse cross section of the body housing whereby an internal space of the body housing is effectively utilized and an axial dimension of the engine is shortened. Since the compressed air is supplied to the heat exchanger through peripheral walls of the body housing having a double construction, prevention of heat radiation from the body housing and effective utilization of an internal space of the body housing are realized.

    摘要: A turbocharger comprises a compressor housing, a turbine housing, and a central housing with a shaft rotatably supported therein. The shaft supports on its respective opposite ends a compressor wheel and a turbine wheel that are rotatably disposed in the compressor housing and the turbine housing, respectively. The central housing has a large water jacket near the turbine housing and substantially coextensive therewith for storing cooling water to cool bearings which support the shaft. The turbine housing accommodates a shroud including a vane holder on which fixed and movable vanes are alternately supported for directing exhaust gases to the turbine wheel through variable restrictions. The vane holder or base plate has a radially outer flange and an annular boss which position the shroud axially and radially with respect to the central housing.

    摘要: The boost pressure of a blower such as a turbocharger or a supercharger which is driven by the exhaust gas or the power output from an engine is controlled under closed-loop control when the boost pressure is in a steady state, and under open-loop control when the boost pressure is in a transient state. When the boost pressure is in the transient state, the open-loop control which may be map control is carried out for relatively good accuracy and high stability. When the boost pressure is in the steady state, the closed-loop control, i.e., highly accurate feedback control, is effected. Therefore, an improved response and stability can be achieved in boost pressure control.
