Title: Torsional damper
Inventor: KURATA TOMOYUKI
IPC: F16F15/16
Filed: 1990-08-03
Abstract: PURPOSE:To prevent lowering of a damping force without dispersion of a product by forming the length of a part in parallel with a rotary shaft in a gap in the direction orthogonal with the rotary shaft longer than a half of the overall length and forming it between a hub and a damper mass. CONSTITUTION:When a rotary shaft rotates, a hub 2 rotates together and a part between the hub 2 and a damper mass 4 relatively motions by torsional oscillation, and shearing deformation is given to a viscous fluid L by this motion and a damping force is generated. As this damping force is in inverse proportion to the measurement of a gap 5, if the damper mass 4 moves in the axial line direction of the rotary shaft 1 and extends the breadth of the gap 5, the damping force is radically reduced. However, as the major part of the gap 5 is in parallel with the axial line direction of the rotary shaft 1, the measurement of this gap 5 in parallel is not changed. Additionally, as a part of the gap 5 formed between an elastic body 3 is small, dispersion of a product at the time of manufacture is lessened and adverse effect during rotation is also lessened.

IPC: G06F11/30
Filed: 1998-07-22
Abstract: PROBLEM TO BE SOLVED: To reduce hardware scale, to relax hardware control timing conditions related to timer control, to reduce the processing of a firmware and to improve accuracy. SOLUTION: When timer overflow does not occur, a one-timer count slot 14 reads a timer overflow schedule timer value from a memory (read slot R) and compares the read timer overflow schedule timer value with a current timer value (check slot CK) and only when the timer overflow occurs, a stop value is written in the same address as the timer overflow schedule timer value used for comparison (write slot W). Thus, the write slot W is not required for the one-timer count slot 15 when the timer overflow does not occur.

IPC: G06F17/22
Filed: 1993-08-20
Abstract: PURPOSE:To input KANJI by means of an associated input system to which an operator gets used by retrieving address information based on associated input information inputted from a keyboard. CONSTITUTION:The name of a place is stored in a first memory 3 by KANJI, and an association table restricted by an association system is stored in a second memory 4. A user program receives associated input information following a cantic association system inputted from the keyboard 1, supplies the associated input information for the retrieval processing of the association table and writes KANJI JEF codes corresponding to two KATAKANA (the square form of KANA (Japanese syllabary)) codes as association input on a retrieval key field. When the operator sequentially inputs KANJI after the input of one KANJI character and he inputs the name of the place (the name of a prefecture), the user program transfers the data to an address data base retrieval system and receives the result. Thus, address information can be retrieved without depending on the unexperienced KANA character KANJI conversion system of a word processor.
