Title: Steering system used for two rear axles type vehicle
Inventor: IWASAKI SABUROU
IPC: B62D13/04
Filed: 1983-01-29
Abstract: PURPOSE:To reduce a turning radius along with the reduction of side slip by controlling a control valve in response to signals sent from a car speed sensor and a steering amount sensor. CONSTITUTION:A signal from a car speed sensor 41 is always inputted into a control unit 48 when a truck 50 runs. When forward car wheel axles 14, 15 are steered by the operation of a steering wheel 19 at low speed travelling, a steering sensor 42 detects the rotational speed, direction of rotation, and turning angle of a steering shaft 20, sending an output signal to its control unit 48. Said control unit 48 controls a solenoid valve 45 based on a previously stored turning pattern in response to said output signal, allowing an actuator 36 to be driven and the rear car wheel axles 29, 30 of a rear steering 26 to be steered.

Title: Horizontal scanning circuit and liquid crystal display device
Inventor: OTA SUNAO
IPC: G09G3/36
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To realize a clear picture having no ghost by providing a horizontal scanning circuit with delay circuits and a control circuit so that a suspension period is generated in between adjacent signal line selection switch driving pulses. SOLUTION: Signs I1 , I2 , INV1 , INV2 are respectively outputs of inverter circuits I1 , I2 , INV1 , INV2 and a video signal is the input video signal to an input terminal and the input video signal is the signal outputted via a buffer circuit while sampling the video signal by a sampling clock SCLK. Since output starting timings of signs INV1 , INV2 , that is, output starting timings of signal line selection switch driving pulses SX1 , SX2 are delayed, a suspension period is generated in between the output periods of INV1 , INV2 (SX1 , SX2 ). An unwanted signal is prevented from being impressed on a signal line by applying the suspension period to a time when the video signal is changing and then the picture having no ghost is obtained.

Filed: 1997-01-28
Abstract: PROBLEM TO BE SOLVED: To attain highly accurate measurement, long-term outdoor installation and read at a distant place from a measurement point by forming a gage so that a graduation line and an index line flatly intersects with each other in an installed state and measuring travel of the intersection of the graduation line and the index line due to displacement caused. SOLUTION: The displacement measuring gage comprises a flat plane A equipped with a graduation line 1 on a side of a plane (a) and a flat plane B equipped with a plurality of index lines 2 marked with an angle θ with respect to a shorter-side direction line having an equal length to that of the graduation line 1. The flat plane B is fixed to one of sides across a crack so that a displacement direction line S aligns with a displacement direction. Then the flat plane A is fixed to an object to be measured to overlap on the plane B to the other side across the crack so that the graduation line 1 is orthogonal to the displacement direction line 1 and intersects with at least one of the index lines 2.  When displacement occurs on the object, the planes A, B are displaced in the displacement direction in opposite directions respectively, resulting in movement of a reading intersection 4 which is the intersection of the graduation line 1 and the index line 2. Thus this moving amount is measured to obtain an actual displacement amount.

Filed: 1982-01-29
Abstract: PURPOSE:To prevent the air fuel ratio in a cylinder from scattering between cylinders at respective suction strokes by a method wherein the air is fully mixed with the fuel accoding to the swirl of the suction air in the cylinder and  at the same time the thoroughly atomized mixture with small inertia is re- circulated.

Because the atomized mixture is re- circulated under its state with small inertia through a suction recirculation passage, which opens toward downstream along the flow direction of the swirl S, at compression stroke, the fuel component is prevented from directly flowing back to the suction recirculation passage 11. In addition, because a shroud 15 is provided on the valve head 9a of a suction recirculation valve 9, the inertia of the swirl S is checked by the shroud 15.
