Title: Spindle motor
Inventor: TANAKA KATSUHIKO
IPC: G11B19/20
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To reduce electric power consumption at the time of high-speed rotation, by fixing a stator whose cylindrical surface of a cylindrical rotor magnet is fixed on a supporting member, and fixing a magnetic fixed yoke which faces the magnetic body of a rotating member at an interval in the axial direction. SOLUTION: This spindle motor is constituted so that a rotating member is supported against a supporting member, by inserting a shaft 6 which is fixed on a hub 1 and whose center line is directed vertically in an insertion hole formed at a sleeve 7 fitted at a base 5. This motor is constituted by making the inner periphery of the cylindrical surface of a cylindrical rotor magnet 10 fixed on the hub 1 through a back yoke 12 face a stator 11 of the motor fixed on the base 5 at an interval in a radial direction. A bearing which supports the rotating member is constituted of a thrust dynamic-pressure grooved fluid bearing 2A formed out of a thrust plate 3 and a radial dynamic-pressure grooved fluid bearing 2B formed out of the sleeve 7. It is thus possible to reduce electric power consumption at the time of high-speed rotation.

Title: Recording data judging device
Inventor: TANAKA KOJI
IPC: G11B20/18
Filed: 1988-06-29
Abstract: PURPOSE:To attain high speed processing and to facilitate block control with simple constitution by comparing a reproduced code word with a correct code word before recording and verifying the recording data based on the relation between an error code word number and an error correction capability. CONSTITUTION:When a code word is reproduced from a recording medium 18, the comparison between the reproduced code word and the code word before recording is applied by a comparison section 14 in parallel. From the relation between number of coded words erroneously recoded which is obtained from the result of comparison and the error correction capability, the accuracy of the recorded data is judged. Since the reproduction phase G and the comparison phase H are executed in parallel in this way, the entire processing time is reduced remarkably. Since an EDAC (error detection and correction) section of complicated constitution is not required, the entire circuit scale is reduced and the block control is simplified. Thus, the processing speed is quickened and the circuit constitution is simplified and the block control is facilitated.

Filed: 1980-11-19
Abstract: PURPOSE: To prevent aging deterioration of heat conducting performance, by forming a closing section by allowing a heating pipe closing section to protrude into a heat pipe chamber.  
     CONSTITUTION: When an open end of a heat pipe 32 is pressed against a die 31 which is provided with a concave surface 29 and the center 30 of the concave surface 29 is closed, and then, the open end is softened and closed by frictional heat caused by making the die 31 and the pipe 32 slide symmetrically, a closed end 22 is protruded into a chamber of heat pipe 1.

Title: Hydraulic pressure controller for antiskid device
Inventor: ARIKAWA TETSUO
IPC: B60T8/1761
Filed: 1984-07-31
Abstract: PURPOSE:To dispense with an accumulator, by pushing a fluid lying between a piston and a master cylinder back to the master cylinder side with the piston to operate with discharge pressure at a time when the pump discharge pressure goes beyond the first specified one, while letting the discharge pressure escape to a reservoir with the second specified pressure. CONSTITUTION:In time of antiskid controlling, a discharge fluid out of a pump is fed to each of first and second ports 21 and 22 by way of pipe lines 4h and 4i. This discharge fluid acts on a stepped piston 31, and when symmetrical pressure differentials acting on the said stepped piston 31 goes beyond the specified one, this stepped piston 31 moves to the right. Therefore, a tip end part 39a of a valve body 39 is made contact with a pressure accumulating piston 40 whereby a through hole 49 is closed. In addition, when pump discharge pressure goes up, the stepped piston 31 and the pressure accumulating piston 40 both further move to the right and thereby a braking pressure fluid inside an accumulator chamber 42 passes through a pipe line 4a and then pushed back to the master cylinder side. When the stepped piston is further moved to the right, both these ports 21 and 22 are interconnected with each other so that the discharge fluid escapes to a reservoir, thus travel of the piston 31 is limited to some extent.

Filed: 1995-05-24
Abstract: PURPOSE: To improve the workability by stretching the wire as a leading line between tops of a plurality of anchors installed in an existing wall, and holding an external wall member through a locking piece fixed to the wire. CONSTITUTION: Anchors 3 are installed in an existing wall 5 in the longitudinal or transverse direction with the prescribed intervals, and the wire 4 is stretched between tops of the anchors 3.

Abstract: PURPOSE:To enhance response by sampling the combustion pressure, sensed by a combustion pressure sensor, in accordance with signal from an equal-volume sensor, calculating the mean effective pressure as shown in attached illustration, and by controlling the ignition timing so that this mean effective pressure is maximized. CONSTITUTION:The combustion pressure is sensed by using a combustion pressure sensor furnished at each cylinder. An equal-volume sensor is equipped, which emits a signal each time the cylinder volume changes by a certain specified amount in synchronization with rotation of the crank shaft. The combustion pressure sensed by said combustion pressure sensor is sampled in accordance with signals from the equal-volume sensor, to calculate the illustrated mean effective pressure of the combustion pressure. At Step 21, the mean effective pressure Pi' in the foregoing cycle is compared with the one Pi at this time, and the ignition timing is controlled in the direction that the mean effective pressure will rise. Thereby the respense is enhanced.
