Filed: 1987-01-16
Abstract: PURPOSE:To attain vector quantization by a few reference vectors by folding an input vector at a plane perpendicular to each reference vector to approach an input vector to a center vector and extracting a bit of information on which side of symmetrical planes the input vector exists in the case of the folding as a vector index. CONSTITUTION:In the case of the inner product of (X0, R0)<0, where X0 is the vector of mean value to be separated and R0 is a 1st reference vector R0, the reference vector R0 is outputted from a gate circuit 15, the output of an accumulator 13 and the inner product are multiplied by a multiplier 16 and the result is subtracted from the vector X0 retarded by a delay circuit 17 by a coefficient 2. That is, the conversion output X1 of a conversion stage block 10 is expressed as X1=X0-2I0.(X0, R0)R0. The vector X1 is converted similarly as X2, X3,..., XN succeedingly and index information I1, I2,..., IN-1 are outputted form each conversion stage. Thus, the number of reference vectors is minimized as soon as possible and the vector coding system close to an ideal characteristic is formed.

Title: Recording method
Inventor: ISHIODORI MAKOTO
IPC: G11B27/036
Filed: 1988-01-14
Abstract: PURPOSE:To prevent recording signals at the front and the rear positions of a track to be inserted from being erased by disabling erasure currents in the periods of first and last fields to be inserted, and performing over-recording by increasing a recording current at the time of recording. CONSTITUTION:The erasure current C is disabled in the periods FS and FE of the first and the last one fields in the period where a correction insert instruction signal S1 is set at a high level.

Title: Ink jet recorder
Inventor: TAN ATSUTO MINGU
IPC: B41J2/175
Filed: 1994-01-25
Abstract: PURPOSE:To reliably remove foreign particles and ink adhering to a wiper by a method wherein an ink cartridge integrally molded with a wiper wiping member is provided as a replacement part in an ink jet recorder. CONSTITUTION:Repeated wiping results in adhesion of a part of ink wiped by a wiper 8 to the wiper 8 itself. If the ink dries and thickens with the elapse of time, there is much possibility that the wiping performance of the wiper 8 itself may be deteriorated, and the thickened ink may adhere to an ink delivery surface 1a to cause an ink delivery port to be clogged. For wiping ink adhering to the wiper 8, a wiper wiping rib 12 is integrally molded with an ink cartridge as a replacement part out of the same material. In this structure, foreign particles and ink adhering to the wiper 8 can be reliably removed without increasing the number of component parts and integrating processes.

Title: Quick brake spreading chain/belt between road surface and wheel
Inventor: ISHII SUKE
IPC: B60T1/14
Filed: 1979-01-23
Abstract: PURPOSE: To accurately and suddenly stop a car by making a chain belt lie idle and traveling a wheel on this chain belt.  
     CONSTITUTION: When a car suddenly stops during traveling, the pinion of the roll 1 revolves backward with the rack 11 by running over the brake actuation rod 6 of a car operator room. This revolution permits the chain belt 8 wound by the rack 11 to fall on a road surface and to lie idle. It permits also the wheel 12 to run over this chain belt 8. This running over permits the chain belt 8 to be exceedingly firmly pulled backward and to be tightly contacted on the road surface. As a result, the car suddenly stops.

Filed: 1987-01-14
Abstract: PURPOSE:To reduce overshoot in control, by providing a path which communicates a piston upper part room with a main value opening, and closing a main valve before pressure on a secondary side rises excessively, in a pilot type reducing valve. CONSTITUTION:A piston ring 25 is fitted in a groove after forming the groove on the peripheral wall of a piston 20, and it is housed slidably freely in a cylinder 22. The upper end of a piston bar 23 is connected to the lower plane of a movable wall 27 with a hemispherical plane 70, and the lower end is abutted with the main valve 18 in the value opening 14. The path 72 is provided from the upper plane to the lower plane of the movable wall 27 centering the axis of the piston bar 23, and a side opening 74 is opened at the side plane of the piston bar 23, then, it is communicated wit the path 72. When a flow rate passing the main valve opening 14 increases and the pressure on the secondary side starts to rise, the pressure is decreased because flow velocity is increased, and a fluid body on the upper part of the piston is sucked to the main valve opening via the path 72, thereby, the pressure is decreased further. In such a way, the main valve is operated so as to be closed before the main valve is opened excessively and the pressure is increased excessively.
