Title: Synthetic resin extruder
Inventor: NAKAMURA KENSAKU
IPC: B29C48/395
Filed: 1984-02-03
Abstract: PURPOSE:To obtain a synthetic resin extruder that obviates the vent-up from a vent hole and enables the extrusion operation to be carried out efficiently, by providing jetted resin forcing means in the vent cylinder of the vent hole on a raw material forcing port side. CONSTITUTION:A jetted resin pressing means comprises a screw 22 extending in a vertical vent cylinder 9a constituting a vent hole 9, the upper part of the screw 22 being driven via a reduction gear 23 by a motor 24. Though a resin raw material in a semi-melted state inclines to vent up to spout up from the vent cylinder 9a, since the screw 22 is rotated by a motor 24 to hold the resin raw material downward at all times, the vent-up can be obviated completely. The gas containing moisture formed during the melting in the heating cylinder 3 is released outside via the gap between the vent cylinder 9a and the screw 22 from a discharge port 9c of a cover 9d provided at the side of the vent cylinder.

Abstract: PURPOSE:To enable compacting, and to attain excellent sealing properties by composing a discharge-opening sealing means of a holder and a cap, constituting the cap of a material having elasticity and fast sticking the cap to a discharge- opening arranging surface by utilizing elasticity. CONSTITUTION:A discharge-opening sealing means having a cap 2 disposed in tension on the front of a holder 3 is provided, the cap 2 consists of an elastic body, and made up of a joining fixing section to the holder 3 and an edge section 2c for disposing tubular structure 2b in tension to a fixing section 2a, and these members are monolithic-molded.

Abstract: PURPOSE:To improve the bit precision by applying conversion processing to quantization data of a difference between picture data and representative data for each prescribed block. CONSTITUTION:When the motion compensation mode is the in-picture prediction mode and a dynamic range of a block of picture data in 10-bit precision from a computing element 4 exceeds 8 bits, a block quantization device 7 converts a 10-bit block into data of 8-bit precision from the computing element 4 and outputted to a difference signal coder 8. On the other hand, in the case of the inter-picture prediction mode, a representative value calculation circuit 5 detects a maximum value and a minimum value of an arithmetic operation output of the computing element 3 and its mean value is outputted to computing elements 4, 11 as representative data of a block of the picture data in 10-bit precision outputted from the computing element 3. A difference between the block of the picture data in 10-bit precision from the computing element 3 and a mean value of the block from the circuit 5 is taken and outputted to a quantization device 7.

Title: Airconditioner
Inventor: ICHINOMIYA TOSHIKI
IPC: F24F1/00
Filed: 1988-01-29
Abstract: PURPOSE:To make it possible to carry out heat recovery during ventilation in terms of an outdoor heat exchanger, by installing a communication section between an indoor heat exchanger-built in block and an outdoor heat exchanger-built in block, forcing ventilation air from indoors to partially pass through an outdoor heat exchanger so as to discharge exhaust air, and introducing an open air so as to carry out ventilation. CONSTITUTION:A supplied air 8 either cooled or heated by an indoor heat exchanger 2 is returned to an airconditioner 1 as a post ventilation air equivalent to an indoor load, and it is divided into an exhaust air 12, which passes through a damper 7A and an outdoor heat exchanger 3 by an exhaust fan 6, and a circulation air 13, which is supplied by an air supply fan 4 together with an open air 10 which has passed through a damper 7B. The exhaust air 12, when discharged, promotes the condensation of an refrigerant in the case of cooling operation, and evaporation of an refrigerant in the case of heating operation by an outdoor heat exchanger 3. In summer when cooling operation is carried out, the exhaust air 12 is colder than an outdoor temperature, while in winter when heating operation is carried out, the exhaust air 12 is warmer than the outdoor temperature, which makes it possible to carry out a specified condensation or vaporization with less wind volume. It is, therefore, possible to minimize the power required to drive a fan compared with such cases where condensation and vaporization are carried out by an outdoor air alone, thereby collecting the heat substantially on a refrigerant circuit.
