Title: Front and rear wheel steering device for vehicle
Inventor: KOMAMURA SEIJI
IPC: B62D5/26
Filed: 1985-09-27
Abstract: PURPOSE:To enable the neutral position of rear wheels to be maintained during high speed running, by a method wherein working oil is fed to a rear wheel cylinder, capable of steering rear wheels, in linkage with rotation of a handle rotary shaft, during high speed running, the rear wheels can be steered through the working of a centering mechanism, and during low speed running, the rear wheels can be steered following steering of front wheels. CONSTITUTION:When a handle H is operated so that front wheels Tf are turned in either a right or a left direction, rear wheels Tr can be also automatically steered following said steering. During linear running, the front wheels Tf are not steered and the rear wheels Tr are not steered, but when reliable stop of steering is executed, the feed of working oil to a rear wheel cylinder C is stopped. Especially during high speed running, with a rear wheel centering mechanism 2 actuated, a neutral position is maintained through utilization of a spring force. Thus, when turn or oblique running during low speed running of a working vehicle is executed, the rear wheels can be steered following steering of the front wheel Tf. When a vehicle is switched to high speed running, steering of the rear wheels is stopped, and the neutral position of the rear wheels can be easily maintained.

Title: Chrominance signal processing system
Inventor: OTSUBO TADASHI
IPC: H04N9/79
Filed: 1989-08-22
Abstract: PURPOSE:To prevent the loss of hue information by substituting the DC signal of a prescribed level for the input chrominance signal of a carrier wave band in a specified period. CONSTITUTION:The specified period is determined, and by substituting the DC level signal for the input signal in this period by a superposition component removal circuit 30, an achromatic color level is prescribed for the B-Y signal and the R-Y signal of a base band demodulated by demodulators 5, 6. Then, the amplitude relation of each part of the B-Y signal and the R-Y signal to this achromatic color level is never changed according to the size of the superposition component or signal processing, and in addition, these achromatic color levels are clamped by clamp circuits 17, 18 so as to be a prescribed reference level. Accordingly, the B-Y signal and the R-Y signal outputted from the clamp circuits 17, 18 are not impaired at the relation of the level of each part to the achromatic color level. Thus, in a carrier chromatic signal obtained at an output terminal 28, the hue information is maintained correctly, and the color reducibility of a monitor picture is improved.

Title: Hybrid automobile
Inventor: SEO NOBUHIDE
IPC: B60L50/16
Filed: 1998-07-29
Abstract: PROBLEM TO BE SOLVED: To enhance the safety of travelling by preventing the generation of a sudden stall in the passing-travelling state. SOLUTION: In a hybrid automobile provided with both an engine 1 and a motor 4 fed from a battery 5 as driving sources, a drive-stopping threshold value in an accelerated area is set lower than that in a non-accelerated area. By this configuration, when a vehicle travels in the accelerated area, driving of the motor 4 is continued until the remained storage capacity of the battery 5 becomes considerably little, and the accelerated travelling can be continued for a longer time. Thus, a sudden stop of the motor 4, for example, in passing other vehicle causing the vehicle sudden stall is prevented, enhancing the safely of vehicle travelling.
