Patent JP-H03151561-A (JP)
Title: Fuel pump
Inventor: TSUTSUI KATSUHIKO
IPC: F04B43/02
Filed: 1989-11-07
Abstract: PURPOSE:To sufficiently lower pressure within a pump chamber when fuel is taken in so as to enhance the air intake performance of a fuel pump by setting the blocking force for the delivery valve seat of a delivery valve communicated with a pump chamber larger than that for the air intake valve seat of an air intake valve. CONSTITUTION:When an engine is operated pulsating pressure generated in the engine is introduced into a pressure receiving chamber G via an introducing passage 4; when e.g. the negative pressure force of the pulsating pressure acts on the pressure receiving chamber G a partition body 3 moves toward the pressure receiving chamber G to increase the capacity of the inside of a pump chamber P. A delivery valve seat 8 is blocked with a relatively large blocking force by a delivery valve 9 and leakage does not occur from the delivery valve seat 8 to inside the pump chamber P and so pressure within the pump chamber P is sufficiently lowered. Because an air intake valve seat 5 is blocked with a blocking force smaller than the above blocking force by an air intake valve 6, the air intake valve seat 5 is surely opened by means of pressure within the pump chamber P which is sufficiently lowered. Thus fuel contained in a fuel source T is surely taken into the pump chamber P.

Title: Transparent gas barrier film
Inventor: NAGAI ITSUO
IPC: B65D65/40
Filed: 1994-11-24
Abstract: PURPOSE: To reduce deterioration of gas barrier performance due to post- processing, in a gas barrier film consisting of a plastic film and an aluminum oxide thin film formed at its single surface, by taking the thickness and refractive index of the aluminum oxide thin film as particular values. CONSTITUTION: This gas barrier film is provided with an aluminum oxide thin film formed on at least the single surface of a plastic film consisting of a polypropylene film or a polyethylene terephthalate film by means of a physical deposition method or a chemical deposition method. The thickness of the aluminum oxide thin film is 8-50nm. The film thickness smaller than 8nm will not meet the gas barrier performance, while the film thickness larger than 50nm will generate a curling, and degrade the gas barrier performance rapidly at the time of processing. The refractive index of the aluminum oxide thin film is 1.70-1.90. The refractive index of not more than 1.70 makes the aluminum oxide thin film porous to be insufficient in gas barrier performance, while the refractive index of not less than 1.90 makes it difficult to ensure transparency.

Abstract: PURPOSE:To provide a vesicle-containing substance excellent in mechanical strength, having high sensitivity and capable of simply and precisely controlling the mutual diffusion of inner and outer phase substances and a method controlling the mass diffusion of the vesicle-containing substance. CONSTITUTION:A vesicle 11 is formed from an anionic bimolecular film and a cis-trans photoisomerization acceptor 14 and a doner 15 discharging an electron by the irradiation with specific exciting light are absorbed on the interface thereof. Substances 22, 24 reacting with each other are arranged to the inner and outer phases of the vesicle 11. The acceptor 14 generates cis-isomerization by the irradiation with light having a wavelength different from that of the exciting light and trans-isomerization is generated by the chain electron relay between the doner 15 and the acceptor 14 due to the irradiation with the exciting light. The transmission of the substances 22, 24 passing through the vesicle 11 is increased and decreased on the basis of the cis-trans isomerization of the acceptor 14 to control the chemical reaction due to the mutual diffusion of the substances 22, 24 of the inner and outer phases.
