IPC: B22D17/14
Filed: 1983-09-06
Abstract: PURPOSE:To form a product having high quality by die casting at a high yield with high productivity by evacuating the inside of a cavity via a valve constituting a part of the wall surface of a runner provided to a metallic die then injecting molten aluminum into the cavity. CONSTITUTION:A valve 8 which is provided at the terminal of a runner 7 of a die 1 and constitutes a part of the wall surface at said terminal is opened by the operation of a cylinder 6 via a solenoid valve 15 for control and after the inside of the cavity 2, runner 7 and spool 9 of the die 1 is evacuated, the valve 8 is closed. The aluminum melted by heating in a heating column 3 is admitted through a nozzle 4 into the spool 9 and a hydraulic cylinder 11 is driven to advance a piston 12 thereby injecting the molten metal into the cavity 2. Since the inside of the cavity 2 is evacuated, the molten aluminum is packed quickly to each corner in the mold and the die casting product having high quality is obtd.

IPC: C08K5/17
Filed: 1987-07-02
Abstract: PURPOSE:To obtain the title noncolored composition excellent in orientability and high in permittivity, by adding triallyl isocyanurate to a vinylidene fluoride resin. CONSTITUTION:100pts.wt. vinylidene fluoride resin (e.g., vinylidene fluoride/vinyl fluoride copolymer) of a vinylidene fluoride content >=40mol.% is mixed with 0.005-1.5pts.wt. triallyl isocyanurate and the mixture is kneaded and extruded to obtain a pelletized vinylidene fluoride resin composition.

Title: Heat exchanger type blower
Inventor: YARI KENTARO
IPC: F04D29/58
Filed: 1986-07-11
Abstract: PURPOSE:To contrive the reduction in abrasion by friction by increasing the area of contact between a sliding member and a sealing material with a substantially V-shaped cross section in the sliding member and making it possible to disperse the components of the centrifugal force in the direction of the sliding member. CONSTITUTION:An outer circumferential plate 104 which supports a blade 101 from the outer circumferential direction has a sealing material 105 with a substantially annular and V-shaped cross section and elasticity mounted on the outer periphery of the plate 104. A sliding material 109 on which a sealing material 105 slides is constituted of a material of a small resistance to sliding such as stainless steel, etc. and its cross section is substantially V-shaped. When the blade 101 rotates, centrifugal forces F1-Fn act over a length l and force components f1-fn in the direction of the sliding material 109 act to the contact section S of the sealing material 105 as counter actions. By the fact that the counter forces act not on points but on a line, the contact area of the sealing material 105 increases. With this arrangement, the abrasion by friction caused by the rotational sliding of the sealing material 105 is not local and the resistance to friction is improved a great deal and it is possible to secure a constant heat exchange efficiency.

IPC: H01S5/00
Filed: 1991-07-04
Abstract: PURPOSE:To reduce leak current by using a structure wherein a p-block layer and an n-block layer are connected via a resistor. CONSTITUTION:An insulative film 9 is formed in a contact layer 8 so as to reach at least a p-InP substrate 1. A hole for contact of an electrode is formed in the insulative film 9. At the same time, a hole is formed in the insulative film 9 by selectively etching the vicinity of the boundary of a p-block layer 6 and an n-block layer 5. The same electrode metal as an electrode 10, i.e., a resistor 11 is evaporated at a part 12 where the insulative film 9 is eliminated. The collector and the base of a transistor in a thyristor 27 are connected via resistor R. Hence leak current is reduced especially when a driving current is large. The leak current can be reduced by decreasing the resistance value of the resistor R.

Filed: 1988-06-30
Abstract: PURPOSE:To prevent duplication processing of a telegraphic message by adding a serial number synchronized between a sender side and a receiver side to the telegraphic message and comparing the serial number of the sender side and the receiver side. CONSTITUTION:A node A sends a telegraphic message (a) to a node B and a serial input serial number at the sender side is given to the telegraphic message (a). Moreover, the node B returns a reception end telegraphic message (b) to the node A and the serial expected serial number of the receiver side is revised on each occasion of the telegraphic message reception. Then the telegraphic message is received, the input serial number and the expected serial number are compared and when the input serial number is equal to or larger than the expected serial number, it is discriminated not to be duplicated reception, the telegraphic message is processed and when the input serial number is smaller, it is discriminated to be duplicated reception of the telegraphic message and the message is disregarded. Thus, when a fault takes place in a communication path and the telegraphic message is resent in a deputy path, since the serial number of the sender side and the receiver side is compared, the duplicate processing of the telegraphic message is prevented.
