Title: Buffer controller
Inventor: YAMAZAKI ATSUSHI
IPC: G06F9/38
Filed: 1989-05-24
Abstract: PURPOSE:To increase the capacity of data with the small number of hardwares by storing operand data overflowing an operand buffer circuit out of prefetched operand data in an instruction buffer circuit at the time of processing a variable length data processing instruction. CONSTITUTION:An instruction buffer control circuit 13 sends an invalidation instruction signal to an operand buffer storage invalidating circuit 18 through a line 120. The circuit 18 invalidates an operand buffer storage instruction signal based upon the instruction signal so that main storage reading data are not written in the operand buffer circuit 10. Thereby, operand data overflowing the circuit 10 are successively stored in the position of the instruction buffer circuit 11 specified by an instruction buffer writing address applied through a line 111. Thus, operand data to be prefetched can be increased without increasing the number of hardwares at the time of processing the variable length data processing instruction.

Title: Electric rotating machine
Inventor: KASAI TOMIO
IPC: H02K5/173
Filed: 1990-05-23
Abstract: PURPOSE:To protect a bearing against damage by making one or more pressure equalizing holes at the outside of a bearing boxmounted on the wall section of a bracket thereby reducing the air flow through the bearing in an electric rotating machine having a fan directly coupled to the end face of the bracket. CONSTITUTION:A pressure equalizing hole 21 or 22, communicated with the interior of an electric rotating machine 1, is made at a position close to a bearing box 8a mounted on the wall section 8b of a bracket 8. The pressure equaling hole 22 is applied on an enclosed fan type electric rotating machine. Even if air containing much moisture is fed upon operation of the fan, it is discharged through the pressure equaling holes 21, 22 having lower conduction resistance than a shaft-through section M and scarcely passes through a bearing 7, and thereby deterioration or removal of grease in the bearing 7 can be prevented. Furthermore, since the air is communicated through the pressure equalizing holes 21, 22 with the outside, over saturated air is discharged to the outside hardly forming dew when an electric rotating machine stops operation and is cooled in high temperature air.

Title: Scanning image processing method
Inventor: TRETTER DANIEL R
IPC: H04N1/409
Filed: 1997-05-07
Abstract: PROBLEM TO BE SOLVED: To maintain the continuous gradation and the resolution for a text image by using a correction median filter to process an image pixel of a scanned image thereby minimizing a moire pattern in the scanned intermediate image. SOLUTION: When it is discriminated that one pixel of an image scanned by a document 140 belongs to a continuous gradation image to be scanned, a moire reduction module 133 does not process the pixel and then the pixel value is not revised. Thus, details in the continuous gradation image of the scanned image from the document 140 are kept. Furthermore, when it is discriminated that the pixel does not belong the continuous gradation image, the moire reduction module 133 uses the correction median filter to process the pixel thereby minimizing the moire pattern in the intermediate image of the scanned image. The filter window of the correction median filter is designed so as to pass the pixels belonging to the text image of the scanned image of the document 140 without any correction.

Title: Rotary head
Inventor: INOUE KIYOSHI
IPC: F16C39/06
Filed: 1984-06-26
Abstract: PURPOSE:To stably and smoothly rotate a rotor by setting circuit constants so that a resonance occurs in a resonance circuit of the coil of a pole when the rotor is displaced by an external force. CONSTITUTION:If a rotor 1 is displaced from a central axis by an external force, the inductance of an exciting coil of a pole of the side that a pole gap expands such as, for example, of a coil 41 decreases, and circuit constants are accordingly set to cause a resonance in an exciter. If the resonance occurs, an exciting current increases, and the magnetic attraction force increases for the rotor 1. Therefore, the rotor 1 is returned to the center of the axis. In other words, a rotary motor performs its magnetic bearing action by itself to stably and smoothly rotates while always maintaining the rotation at the center of axis.

Filed: 1993-06-02
Abstract: PURPOSE:To prevent the flowing out of paste and to prevent the bad contact of wire and imperfect connection owing to exfoliation at the time of resin sealing, by providing a surrounding frame between a semiconductor element of a semiconductor device and a die pad and a wiring pattern. CONSTITUTION:Paste 5 composed of an adhesive agent, etc., of viscous fluid is applied on a die part 3 provided on a substrate 1. Immediately after this, a semiconductor element 4 is mounted and the paste 5 is hardened to fix the semiconductor element 4. A surrounding frame 7 made out of epoxy material is placed between the die pad 3 and the wiring pattern 2. Since the surrounding frame 7 prevents the flowing out of the paste 5 made out of an adhesive agent, etc., and applied on the die pad 3, a short circuit does not occur even if the paste 5 contains a conductive substance, for example. Accordingly, bad contact between the die pad 3 and the wiring pattern 2 does not occur. Besides, it becomes possible to prevent the paste 5 made out of an adhesive agent, etc., from flowing out and spreading. Consequently, incorrect connection and bad contact can be prevented.
