Title: Method for molding optical disc
Inventor: INOTSUKA AKIHIRO
IPC: B29C45/00
Filed: 1986-04-09
Abstract: PURPOSE:To make the birefringence of a board small and improve its C/N ratio by a method wherein the axial interval of a molding cavity is increased during a part of the time ranging from the start of injection to the dwelling process. CONSTITUTION:Two axially sliding members 20 and 30 are provided in order to axially increase a molding cavity. The axial interval T0 not shown of the molding cavity 4 at the start of injection process is set to the smaller then the desired axial dimension or thickness t1 of an optical disc, which is the final molded item to satisfy the formula: t1/10<t0<9t1/10. In operation, the dimension t0, which is set at the start of injection process, is increased continuously or stepwise during injection process or during the time ranging from the start of injection process to the initial stage of the dwelling process to the desired final dimension t1. Because the injection process lasts for about 0.5-2sec, the above-mentioned change of the axial interval is done by controlling the hydraulic pressures fed to a mold clamping mechanism (not shown) and to the axially sliding member 30 by means of a computer.

Title: Oxygen enriching filter apparatus
Inventor: SUZUKI SHUNSUKE
IPC: A01K63/04
Filed: 1990-03-28
Abstract: PURPOSE:To set the amount of dissolved oxygen in water to the theoretical saturated value of water or more within a short time by constituting an oxygen enriching filter apparatus of an Al sintered porous body wherein at least a part of the surface of an Al-base porous body is composed of aluminum whiskers. CONSTITUTION:Water 11 is received in a water tank 11 and an oxygen enriching filter apparatus 1 is vertically introduced into the water tank 10 and air is introduced into the apparatus 1 under pressure for about 5min by an air pump 15. This air passes through a connection pipe 12 to be introduced into the oxygen enriching apparatus 1 in water and is discharged into the cylinder of a filter main body 6 from a conduit 4. Since the cylinder is a filter formed from an Al porous body, the cylinder is perfectly filled with water when immersed in water and the air discharged from the conduit 4 is diffused in the water within the cylinder. When the diffused air passes through the filter main body 6, said air is diffused from the numberless void parts of the Al porous body to generate numberless fine air bubbles and the amount of dissolved oxygen in water is enhanced.

IPC: F02B75/02
Filed: 1994-04-19
Abstract: PURPOSE:To suppress blowing-through of scavenging air to a minimum extent so as to improve output and fuel consumption. CONSTITUTION:It is a 2-cycle engine in which an exhaust passage and a plurality of scavenging passages are formed in a cylinder block 1 and a plurality of scavenging ports 4a 7a are opened across an exhaust port 2a in the peripheral direction of a cylinder bore 8. The shape of the scavenging port 4a is substantially pallallelogram whose sides ab and cd on the right and left are inclined, and side walls 4b, 4c on the right and left of the scavenging passage which are continuous with the scavenging port 4a are inclined substantially in parallel toward the scavenging port 4a and in the direction in which scavenging air which flows in the scavenging passage leaves the exhaust port 2a. Since scavenging air flows along the inclined side walls 45, 4c of the scavenging passage in the direction in which scavenging air leaves the exhaust port 2a, scavenging air becomes a stream having strong directivity and acts as an air curtain which blocks blowing-through of scavenging air which flows from the other scavenging passage into the exhaust passage so as to achieve the aimed improvement.
