Title: Speed change gear power transmission system with planetary gears
Inventor: MORISAWA KUNIO
IPC: F16H3/44
Filed: 1984-11-29
Abstract: PURPOSE:To make it possible to lessen length in an axial direction by making the gear case member bear a thrust force appearing on a sun gear without any help of a flanged member, and reducing the thickness of the flanged member. CONSTITUTION:A flanged member 260 gives an axial motion transversely by a thrust force appearing on a primary sun gear 212. That flanged member 260 is spline connected to a drum 258 for permitting their axial motion and the thrust force is not transmitted to the clutch system 250. Consequently, it is enough if the thickness of the flanged part 260 is decided after consideration of only normal torque transmission and it is possible to reduce plate thickness and shorten the axial length.

Title: Vehicular brake
Inventor: YASUDA TAKESHI
IPC: B60T7/12
Filed: 1996-09-25
Abstract: PROBLEM TO BE SOLVED: To prevent the accident of automatic starting of a vehicle during its stop caused by leaving no manual brake or slackening of the brake by controlling locking/unlocking of the door of the vehicle based on a radio signal from a transmitter and determining no occupants in the vehicle when the locking of the door is detected. SOLUTION: The antenna 2 of a keyless entry ECU 3 receives a radio wave signal transmitted from an ignition key 1. The keyless entry ECU 3 equipped with a receiver combines a control signal for opening/closing the lock of a vehicular door with the radio wave signal received by the antenna 2 and outputs the signal and performs opening/closing of the door while making a solenoid 31 conductive or non-conductive. Normally, a door locking opening/closing control signal is outputted from the keyless entry ECU 3 to the solenoid 31 and a signal indicating the opening/closing of the door lock is transmitted to a parking brake ECU 12. A short sensor 9 detects the weight of a driver by a limit switch provided in the seat of a driver's seat and outputs the result of detecting the existence.

Title: Travelling stabilizer for vehicle
Inventor: ARAI KENTARO
IPC: F16H48/36
Filed: 1997-09-18
Abstract: PROBLEM TO BE SOLVED: To correct the inclination of a vehicle without operating a brake, by comprising a means for controlling a differential rotation generating device which independently operates the left and right brakes of the vehicle in a power- off state, and generates the differential rotation on the left and right driven wheels by the output torque of an electric motor in a power-on state. SOLUTION: First of all, whether a slip angle θ of a vehicle is more than a specifid value θs or not is judged (S1). In a case of θ<θs, whether an accelerator switch is switched on by the pedalling of an accelerator pedal, or not is judged (S2). When the accelerator pedal is off, the left and right brakes are independently operated, so that the yawing moment for reducing the slip angle θis generated (S3). Further in a case of θ<θs, and in the power-on state, a differential rotation generating device is operated to generate the yawing moment for reducing the slip angle θ. Whereby the inclination of the vehicle can be corrected by the differential rotation generating device in the power-on state, and the durability of the brake can be improved.

Filed: 1994-10-19
Abstract: PURPOSE: To reduce the power consumption, to raise the luminance, and to reduce the dead space by arranging a single-tube fluorescent lamp around a light guide means and leading out the lamp electrode of one end and that of the other in the same direction. CONSTITUTION: A U-Shaped Single-tube lamp is used as a fluorescent lamp 1 and is arranged around three sides of a plane quadrangular light guide body 2. Lamp electrodes 1a and 1b in one end and the other of this fluorescent lamp 1 are led out in the same direction. Consequently, the quantity of light of the luminous flux made incident on the light guide body 2 is increased by the increase of length of the lamp in comparison with a straight double-tube lamp or an L-shaped tube lamp in the edge light system, and the luminance of light emission is raised. Since lamp electrodes 1a and 1b are led out in the same direction, the dead space is reduced. Preferably, first and third sides of the U-shaped fluorescent lamp 1 arranged around three sides of the light guide body 2 are made free, and the lamp 1 is fixed by the second side.  Thus, a trouble like a break of the fluorescent lamp 1 is prevented even if this device is used in a place of much oscillation like a vehicle.
