Title: Vehicle headlight
Inventor: OSHIO HIROHIKO
IPC: F21S8/10
Filed: 1999-01-13
Abstract: PROBLEM TO BE SOLVED: To prevent a light distribution pattern from being shifted from a designated light distribution pattern by a deflection of a shade, in a structure in which a low beam and a high beam are switched by moving the shade. SOLUTION: A displacement regulating block 26 for regulating the displacement of a shade 22 from its position by abutting on the shade 22, when the shade 22 is at a position to constitute a low beam or a position to constitute a high beam is provided. This displacement regulation block 26 sandwiches a stay 22B of the shade 22 from right and left in its V-shaped grooves 26a, 26b, while abutting on the stay 22b, in order to regulate the displacement in its rotating direction and in its right and left directions. Thereby, the deflection of the shade 22 produced by vibration during the travelling of a vehicle is prevented in advance, by producing no backlash of the shade 22 at the low beam position and the high beam position.

Title: Magnetic recording body
Inventor: MIZUNO CHIAKI
IPC: C10M103/06
Filed: 1984-01-17
Abstract: PURPOSE:To obtain the titled recording body having a back layer having a durable traveling property without any increase in the coefficient of friction which is electrically conductive and almost transparent by incorporating at least one kind among polyolefin or polytetrafluoroethylene and polyamide powder and SnO2 powder into the back layer. CONSTITUTION:The powder of polyolefin such as polyethylene and polypropylene or polytetrafluoroethylene and polyamide has a lubricating effect, and prevents an increase in the coefficient of friction. When the magnetic recording layer is treated with heat and compression by a calender roll to mirror-grind the surface of the magnetic recording layer for high-density recording, the acute protrusions of the powder of the polyolefin such as polyethylene and polypropylene and polyamide, etc. contained in the back layer are easily crushed by the temp. and pressure. Since the back layer is elastic and soft, the influence of the back layer on the magnetic recording layer is prevented. The SnO2 powder is simultaneously incorporated to reduce the surface electric resistance of the back layer, and an antistatic effect can be provided.

Title: Automatic transmission
Inventor: MAKIYAMA AKIHIRO
IPC: F16H61/10
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To control speed change so as to maintain always excellent travel performance by changing a part of a low-medium load area of an engine load in the direction for expanding an output rotational speed area to perform a low speed stage of an automatic transmission among a prescribed speed changer pattern when a speed change condition of an auxiliary transmission is put on the low speed side. SOLUTION: When an auxiliary speed change stage is put in a low mode L, a shift pattern SP (a broken line) in a shift map is changed to the large side of output rotational speed V with a point of throttle T opening θTH and T opening θ1 in which an engine becomes maximum output as the origin to SP (a full line) at a high mode H time. Therefore, dependency of speed change on the output rotational speed V is increased, and influence of a change in T opening θTH is made hard to be received, and even if T opening θTH is frequently changed large to a sign B from a sign A, it is not easily shifted up, and a present speed change stage is held until the output rotational speed V increases to a certain degree, and suitable driving torque can be generated.
