Title: An elastomer damper for an actuator cylinder
Inventor: NODA MITSUO
IPC: F15B15/14
Filed: 1998-11-19
Granted: 1999-11-21
Abstract: The elastomer dampers are disclosed at both ends of the actuator cylinder in order to stop the piston moving in the cylinder at its stroke ends. The elastomer damper includes a pair of the protruding portions which abut the piston at its stroke end. The protruding portion has a tapered shape in which the cross sectional area thereof gradually decreases from the base to the top. Therefore, when the piston abuts the protruding portions and compresses the protruding portions, the braking force exerting on the piston gradually increases without sudden change. Therefore, the piston decelerates smoothly at its stroke ends. Further, since the top surface of the protruding portion is formed as a flat plane and the top surface is connected to the tapered side surface of the protruding portion by a round surface, no stress concentration occurs at this portion. Therefore, cracks or breakage of the material to not occur in the top surface even after a long operating time of the actuating cylinder.

Title: Semiconductor apparatus, memory card, and data processing system
Inventor: TSUJIKAWA TETSUYA
IPC: G11C16/02
Filed: 1999-01-28
Granted: 2001-09-01
Abstract: Externally supplied program data is latched into data latch circuits (DLL and DLR). Every time when each of plural write-in operations is carried out, a decision is made to judge whether or not the latched write-in data corresponds to any threshold value of multi-levels. The write-in control information corresponding to the judgment result is latched into a sense latch circuit (SL). Based upon the latched write-in control information, the write-in operation for setting threshold voltages of multi-levels to a memory cell is carried out in a stepwise manner. Even when the write-in operation is ended, the externally supplied write-in data is left in the data latch circuit. Additionally, even when the write-in operation of the memory cell is retried due to the overwrite-in condition, the write-in data is no longer required to be received from the external device again.

Title: Digital to analog conversion method
Inventor: SHIE GUAN-HUNG
IPC: H03M1/66
Filed: 1999-02-08
Granted: 2001-01-21
Abstract: The present invention is a digital to analog conversion method used mainly for outputting all single bits in a digital code sequentially to the digital output port to generate an output signal. Firstly, the weighted code ratio represented by a single bit is multiplied by the unit time to obtain the output signal's output time. The same procedure should be repeated on the next bit until the last bit is processed. The output signal generated can be used directly as a corresponding analog signal. Then, the present invention can be applied for controlling the power elements linearly by direct driving of the power switch or for analog output alignment after integration and filtration.
