Abstract: An inlet port 15 is divided into a plurality of holes 15a, 15b, 15c, 15 by ribs 61a, 61b, 61c. For example, when liquid refrigerant is compressed within a compression chamber, the inlet valve 21 receives excessive load which is about to bend the inlet valve 21 largely toward the suction chamber side. However, the inlet valve 21 is supported by the ribs 61a, 61b, 61c, and therefore the inlet valve 21 is hardly bent, but the inlet port 21 is positively closed.

Abstract: A main stopper recess 70 for supporting a protuberance 21d of an inlet valve 21 during the suction stroke and sub-stopper recesses 71, 72 for supporting side protuberances 21e, 21f of the inlet valve 21 during the suction stroke are formed at an opening edge 6a of the cylinder bore. Due to this construction, even when the area of inlet port 15 is increased, large twisting load is not applied to the inlet valve 21 during the suction stroke, and vibrations of the inlet valve 21 are prevented.

Abstract: There is disclosed a liquid medicine continuous infuser having a basic structure comprising a bag-shaped member that can apply a pressure to a liquid medicine accommodated inside the infuser, an inflow/outflow section for flowing in and flowing out the liquid medicine, and an area positioned inside the bag-shaped member and having a predetermined volume. The above pressure provides a predetermined characteristic curve in relation to the capacity of the bag-shaped member, and the area having the predetermined volume is for increasing the capacity of the bag-shaped member when the liquid medicine is accommodated inside the bag-shaped member. Further, the bag-shaped member is for applying a pressure to a liquid medicine accommodated inside the bag-shaped member along with the predetermined characteristic curve, with a pressure corresponding to the capacity increased by the area having the predetermined volume, when the liquid medicine is accommodated inside the bag-shaped member used, as an initial value.

Abstract: There is provided a vane compressor which prevents leakage of refrigerant gas by decreasing the number of airtight interfaces between component parts and prevents seizure from occurring between its rotor and its side block without surface treatment of the side block. The vane compressor has a cam ring. The rotor is rotatably received in the cam ring. A first head is secured to one end face of the cam ring. A second head is secured to another end face of the cam ring in a manner such that the second head closes an opening of the another end face of the cam ring and one end face of the rotor can be brought into contact with the second head. The side block is received in the first head in a manner such that it closes an opening of the one end face of the cam ring and another end face of the rotor can be brought into contact with the side block.

Abstract: A a cartridge type delivery valve assembly in which a valve seat surface and a valve are integrated in order to assure good seating characteristics in the delivery valve. The delivery valve assembly is formed by fixing together a valve holder provided with delivery holes, a roll valve that is mounted along the internal surface of the valve holder to freely open and close the delivery holes and a valve stopper that fixes the roll valve onto the valve holder and regulates the lift quantity of the roll valve, in an integrated manner using coupling members and the delivery valve assembly thus achieved is mounted in a valve insertion space.

Abstract: A method of making a bottle with a handle, wherein a synthetic resin parison is disposed in half-cylindrical molds with a handle body, which is blow-molded and at the same time integrated with the handle body, characterized in that the parison is disposed between the opened molds; the handle body is tacked to a face of matching faces of the half-cylindrical molds; the molds are closed; and the blow-molding is performed.

Abstract: Provided by the present invention are novel diguanamine derivatives, led by 2,5/2,6-bis(4,6-diamino-1,3,5-triazin-2-yl)-bicyclo[2.2.1]heptanes and 1,3/1,4-bis(4,6-diamino-1,3,5-triazin-2-yl)-cyclohexanes, and derivatives thereof, applications of these compounds in fields such as adhesives and paints, utilization of these compounds in flame-retarding, thermal stabilization and compatibilization methods of resins, thermosetting molding compositions and thermosetting expansion-molding compositions making use of these compounds, as well as polymeric microspheres also using these compounds. These compounds are expected to find wide spread industrial utility as various excellent properties can be obtained by using them.

Abstract: A compressor includes at least one compression space for compressing refrigerant, at least one communication chamber into which the refrigerant is discharged from the compression space, a discharge pressure chamber, and at least one communications passage communicating the communication chamber with the discharge pressure chamber for feeding the refrigerant from the communication chamber into the discharge pressure chamber. The length of the passage is longer than the diameter of the passage.

Abstract: Molten metal is prevented from cooling too quickly when supplied to an injection sleeve of a casting device by applying a heat insulating powder onto an inner surface of the injection sleeve between each supply of molten metal. The heat insulating powder can be applied to the inner surface of the injection sleeve by way of an electrostatic field created between an electrode which has been inserted into the injection sleeve and the injection sleeve itself.

Abstract: A sliding-vane rotary compressor includes a cylinder having a plurality of discharge holes aligned in an axial direction of the cylinder, and a corresponding number of discharge valves normally closing the respective discharge holes. Respective openings of the discharge valves are limited in such a manner as to increase progressively in a direction from a front side to a rear side of the cylinder to thereby produce a pressure difference between the front and rear sides of the cylinder. With this pressure difference, the cylinder is normally urged toward one side and hence is unlikely to oscillate in the axial direction. The compressor thus constructed is capable of operating silently without generating an unpleasant oscillating noise.
