Title: Semiconductor storage device
Inventor: YUTSUGI TATSUYUKI
IPC: H01L29/792
Filed: 1991-09-02
Abstract: PURPOSE:To eliminate a need for a dummy cell and to perform a high-speed readout operation by a method wherein a capacitor which uses a ferroelectric film as a capacitor insulating film is installed. CONSTITUTION:One memory cell is constituted of one capacitor and two MOS transistors 4, 5; a ferroelectric film is used as a capacitor insulating film 8. In addition, a bit line 1, an inverted bit line and a word line 3 are provided. Different potentials are applied on capacitor electrodes 6, 7 through the MOS transistor 4, 5; '0' is distinguished from '1' by the direction of a polarization generated by the capacitor insulating film 8. Then, a residual electric charge generated when '1' and '0' are written is utilized for a readout operation. When the potential difference between the bit line 1 and the inverted bit line 2 is sensed, it is possible to directly perform the readout operation without the intermediary of a dummy cell. Thereby, the readout operation can be performed at high speed.

Title: Shift lever mechanism of mobile agricultural machine
Inventor: NISHIGORI NOBORU
IPC: F16H59/06
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To simplify a machine structure and prevent a machine body from starting reverse suddenly at a maximum speed, by placing a resistor which provides resistance for a shift lever just before reverse maximum speed position when the shift lever is operated in the reverse direction. SOLUTION: A shift lever 8 rocks longitudinally, laterally along a guide slit 14 placed in a shift lever guide 11. A resin plate (resistor) 15 which provides resistance to the shift lever 8 just before reverse maximum speed position is placed on the guide slit 14 such that the resin plate faces it from the left side. When the shift lever 8 is operated in the reverse direction, the shift lever 8 touches the plate 15 to receive resistance, and therefore does not reach the maximum speed position at a stroke. The plate 15 is removably fixed on a shift lever guide 11 with bolts 16, 16. If oblong hole is formed in the plate 15 or the lever guide 11 to adjust an overhang amount of the plate 15, resistance applied to the shift lever 8 can be weakened gradually in the rear side and dispersion in parts can be responded.

Title: Steering force control device of power steering gear
Inventor: KOMAMURA SEIJI
IPC: B62D5/06
Filed: 1985-10-04
Abstract: PURPOSE:To prevent damage to a steering system and the like by warningly enabling an operator to be sensible of such a condition, when it occurs, as operational resistance beyond a normal sphere of functioning works and steering input exceeds a definite value and further the quantity of twist of a torsion bar is remarkably increased. CONSTITUTION:Under a condition where a turning wheel is not steerable due to its contact with an obstacle, when an operator turns a handle strongly and continues a handle turning motion beyond limits of normal steering motion, quantity of twist of a torsion bar 9 connecting an input shaft 3 and a screw shaft 6 grows larger. Then, a notch groove 31 of a cylindrical elastic body 30 and a projection 32 of the input shaft 3 are brought into a condition of being engaged with each other. In this condition, however, the torsional reaction force of the torsion bar 9 added with torsional reaction force of the cylindrical elastic body 30 is fed back to the handle side through the input shaft 3. Accord ingly, a feeling different from one in a normal condition is given to the driver, who senses it and stops operation of steerage.
