A method of forming a protection film of a safety valve element for battery prevents corrosion. The safety valve element is composed of a safety valve element having a metal substrate with a perforated pore and a metal foil laminated on a metal substrate so as to cover the pore, and a protection film is formed by coating an organic coating at least on one side of the safety valve element.

A method of forming a protective coating on a cell safety valve element by coating the cell safety valve element with a protective film to protect metal portions thereof against corrosion, a cell safety valve element coated with a protective film, a cell sealing plate using the element, and an enclosed cell using the plate. The safety valve element comprises a coating (3) obtained by applying an organic paint onto at least one surface of the cell safety valve element (10) consisting of a metal base plate (1) having a through hole (4) drilled therein and a metal foil (2) laminated on the metal base plate (1) so as to block the through hole (4). The sealing plate is formed by bringing the cell safety valve element (10), on which a protective coating (3) comprising an organic resin film is formed, into contact with a cell exterior can sealing plate (6), in which the through hole (4) acting as a safety valve port is drilled so that the through hole (4) in the metal base plate of the cell safety valve element (10) and the through hole (7) in the sealing plate face each other and bonding the both at a portion around the through hole (7) in the sealing plate to form the cell sealing plate. The enclosed cell is formed by fitting and supporting the cell sealing plate at the inner periphery of an opening of the cell exterior can in which are housed an electrode body consisting of a positive electrode, a negative electrode and a separator together with an electrolyte to block the opening in the cell exterior can.

A start operation is continuously performed until the internal combustion engine starts even when an accelerator pedal opening decreases between initiation and termination of the start operation of the internal combustion engine, and an EV mode is selected again. A motor/generator is controlled such that a torque of the motor/generator exerting to reduce a slippage of the second clutch increases as the accelerator pedal opening decreases during control of the second clutch to start the internal combustion engine, compared to a case where the accelerator pedal opening does not decrease during mode switching.

A copolyester film was laminated onto a steel sheet, this sheet having double layers consisting of a lower layer of metallic chromium and an upper layer of hydrated chromium oxide on a tin plated steel sheet in which 5 to 40% of the surface of the steel sheet is covered with plated tin and exposed steel surface and a space between plated tin particles is 0.5 to 50 .mu.m, and a method for production of this copolyester resin film laminated steel sheet which comprises: (a) electroplating with tin under restricted conditions, (b) formation of said double layer on plated tin and exposed steel surface and (c) lamination of the copolyester resin film at above the melting temperature of tin.This copolyester resin film laminated steel sheet is suitable for applications wherein excellent corrosion resistance after severe forming is required, such as deeply drawn cans, drawn and redrawn cans, drawn and stretch formed cans, drawn and partially ironed cans and can ends in which a tab for easy opening is attached.
摘要:
A process for producing a thin tin and zinc plated steel sheet which comprises electroplating zinc on a steel sheet from a zinc electroplating bath containing zinc ions followed by tin-plating the zinc plated steel sheet by immersion or by immersion followed by electroplating in a tinplating bath containing stannous ions, whereby zinc ions from the zinc plated steel sheet replace the stannous ions in the tinplating solution during the immersion tinplating. The resultant solution from the tinplating which contains zinc ions is recycled to make up the zinc electroplating bath.
摘要:
A control apparatus and method for controlling a hybrid vehicle is arranged to prevent shock and to minimize adverse influence on lag and fuel consumption when one of a start/stop control of an engine and a shift control of an automatic transmission is requested while the other control is occurring. The control apparatus includes an engine, a motor/generator, a first clutch, an automatic transmission, an integrated controller, an AT controller and an engine/transmission coordinate controlling section. When a second control request is generated during the first control, the engine/transmission coordinate controlling section starts the second control at a request timing when a condition does not exist such that a shock does not exceed an acceptable level and starts the second control at a later timing when the condition exists such that the shock would exceed the acceptable level if the second control is started at the request timing.

The present invention provides an efficient thin film forming apparatus which is capable of correcting a film thickness so as to take care of a variation in distribution in the film thickness and to take care of the circumferential distribution of the film thickness, as well as a method for forming a thin film using this film forming apparatus. The method comprises the first step of first forming a thin film to a predetermined percentage out of thickness through an opening 8a in a shutter 8, the second step of then using a film thickness monitor 10 to measure the distribution of the thickness of the thin film formed in the first step, and the third step of reducing a film formation rate by an opening 8b in the shutter 8 between a substrate 4 and a sputtering cathode 6 as compared to that of the first step and correcting the thickness of the thin film by an opening 13a in the first film thickness correcting plate 13 between the substrate 4 and the sputtering cathode 6 corresponding to the distribution of the film thickness measured by the film thickness monitor 10 in the second step. Then, the second step is carried out again, during which the film thickness monitor 10 is used to measure the distribution of the thickness of the thin film formed in the third step. Further, the third and second steps are repeatedly carried out.
