摘要:
A parking lock device comprises a parking lock mechanism (12) which locks an output shaft (1A) of a vehicle automatic transmission (1) when a shift lever (18) is changed over to a parking range, and an automatic brake device (14) which brakes the vehicle. When the shift lever (18) is changed over to the parking range at a vehicle speed is not less than a predetermined vehicle speed VSP1, a control unit (15) first operates the automatic brake device (14) to decelerate the vehicle and then operates the parking lock mechanism (12) after the vehicle speed has dropped to less than the predetermined vehicle speed VSP1. By this deceleration, the shock given to the vehicle by locking the output shaft (1A) while the vehicle is running is suppressed. The load of the parking lock mechanism due to the locking of the output shaft (1A) is also alleviated.

A prismatic secondary battery includes a prismatic hollow outer body having a mouth and a bottom and storing an electrode assembly, a positive electrode collector, a negative electrode collector, and an electrolyte, a sealing plate sealing up the mouth of the prismatic hollow outer body, and a positive electrode terminal and a negative electrode terminal attached to the sealing plate; the sealing plate includes a gas release valve at the center between the positive electrode terminal and the negative electrode terminal and includes an electrolyte pour hole on one side of the gas release valve and, on the other side on the front face, a concaved flat face with a height lower than that of the peripheral portion; and the concaved flat face is formed with an identification code.

A sealing plate for a prismatic secondary battery includes a pair of mouths for attaching a negative and positive electrode terminals, one mouth being formed near one end in a longitudinal direction of the sealing plate, and the other mouth being formed near the other end, coining areas used for positioning of an insulating member and formed around the pair of mouths on a front face of the sealing plate, a gas release valve and an electrolyte pour hole formed between the pair of mouths, and grooves formed between the respective coining areas and the long side edge of the sealing plate. The groove has a smaller depth near the gas release valve than the depth near the coining area. Even when the sealing plate is produced through forging, the front face has good flatness and the coining areas are unlikely to have a sink mark or a shear drop.

A nonaqueous secondary battery includes a current cutoff mechanism that cuts off a current in a short period of time in response to a rise in pressure inside a battery outer body in at least one of a conductive path through which a current is taken out from a positive electrode plate to outside of the battery and a conductive path through which a current is taken out from a negative electrode plate to outside of the battery. At least one type selected from an oligomer containing a cyclohexyl group and a phenyl group, a modified product of the oligomer containing a cyclohexyl group and a phenyl group, a polymer containing a cyclohexyl group and a phenyl group, and a modified product of the polymer containing a cyclohexyl group and a phenyl group is present on the surface of the positive electrode plate.

Provided is a prismatic battery resistant to the development of short circuits. The prismatic battery has a structure in which a flat electrode including a positive electrode collector with a positive electrode substrate exposed portion and a negative electrode collector with a negative electrode substrate exposed portion is accommodated in an outer can. At least one of the positive electrode collector and the negative electrode collector has a rib. The rib is provided with an easily bendable part (a thin wall, groove, opening, or notch). The rib is bent at the easily bendable part when force is applied to the tip of the rib to prevent the tip from reaching the outer can by means of an insulation sheet to avoid the development of short circuits between the negative electrode collector and the outer can.

There is provided a PDP in which the structure of the periphery of a protective film is improved, excellent secondary electron emission property is exhibited, and improved efficiency and increased life can be expected. There is further provided a PDP in which occurrence of a discharge delay at the time of driving is prevented, and exhibition of high quality image display performance can be expected even in a high definition PDP that is driven at a high speed. Specifically, a crystalline film containing Sr in CeO2 in a concentration of 11.8 mol % to 49.4 mol % inclusive is formed on the surface of dielectric layer on the discharge space side as surface layer (protective film) having a thickness of about 1 μm. High γ fine particles having secondary electron emission property higher than those of protective film are arranged thereon.

By combining crimping fixing and laser welding, a collector attached to a substrate of an electrode assembly is fixed to a terminal. A negative electrode terminal 19A has a terminal portion formed on one side of a flange portion, and a cylindrical crimping member 19b on the other side. The cylindrical crimping member 19b is inserted through openings formed in a first insulating member, a sealing plate, a second insulating member, and a negative electrode collector 18a. The cylindrical crimping member 19b is crimped in a diameter-increasing direction, and is mechanically fixed in a countersunk hole 18c of the negative electrode collector 18a. A peripheral portion of a thin-walled portion 19d having a thickness smaller than those of other portions formed at the tip end portion of the cylindrical crimping member 19b is thoroughly adhered and welded by a high energy beam to the edge of the countersunk hole 18c.

A prismatic battery is provided with a fixing portion composed of projections 29Aa and 29Ba for fixing the position of a flat electrode assembly 11 and a battery outer can 12 by contacting with an insulating sheet 32 on at least one of a positive electrode collector member 16 and a negative electrode collector member 18. The insulating sheet 32 is provided between the projections 29Aa, 29Ba and the battery outer can 12. Tips 29Ab and 29Bb of the projections 29Aa and 29Ba project from the flat electrode assembly 11 towards the battery outer can 12 side. The height of the projections is smaller than the thickness of the insulating sheet 32. This prevents short-circuiting between the positive electrode collector member or the negative electrode collector member, and the battery outer can. Thus, a prismatic battery suitable for EVs and HEVs with excellent safety can be obtained.
