Title: Character identification system
Inventor: YAMADA YOSHIMI
IPC: G06K9/68
Filed: 1988-04-07
Abstract: PURPOSE:To easily make the character identifying calculation of the title system by providing a feature quantity calculating means, then using feature quantities led from the segments forming the contour of the character, performing comparison and selection processes to recognize a character. CONSTITUTION:Data 1a which are produced by binarizing a character to be identified are inputted to a pattern register 1. The bending points 2a and feature points 3a of the segments forming the contour of the character pattern 1b outputted from th register 1 are respectively extracted at a contour extracting section 2 and feature points extracting section 3. The extracted feature points 3a are inputted to a feature quantity calculating section 4 where the feature quantity 1a of the pattern 1b is calculated from the relative position of each segment connecting each two of the above-mentioned bending points by a prescribed calculation formula. The feature quantity 4a is compared with prefixed reference feature quantities at an identifying section 5 and the reference feature quantity having the smallest difference is selected. The character being made to correspond to the selected reference feature quantity is recognized as the character of the character pattern. Thus character pattern recognition can be performed by a simple method.

Title: Residual pressure mechanism for master cylinder
Inventor: SOMEYA NOBUTAKA
IPC: B60T11/16
Filed: 1978-07-10
Abstract: PURPOSE: To provide predetermined residual pressure in a residual pressure mechanism for a master cylinder in the braking operation after filling brake liquid and permit a brake system to evacuate in vacuum by providing an air bleed valve closing by the liquid pressure difference at a piston returned upon release of a brake.  
     CONSTITUTION: Since an air bleed valve is opened to communicate a communicating hole 6 with a liquid pressure supply hole 15, air in a brake system connected to a wheel cylinder can be effectively evacuated without large resistance if evacuating the air in vacuum from a reservoir tank side. When a brake pedal is returned to return brake liquid, a ball 25 deflects the center lip 22 to thereby move toward the top side of a valve chamber 18 to cause it to be elastically urged by the upper lip 21 to thereby close an upper hole 19. Thus, residual pressure responsive to the set pressure of a spring 13 is imparted to the brake system of wheel cylinder side.

Title: Quartz oscillating circuit
Inventor: HIRABAYASHI HIROYUKI
IPC: G04G3/04
Filed: 1981-06-02
Abstract: PURPOSE:To make temperature compensation for the circuit with a temperature compensating capacitor having the positive or negative temperature characteristics, by setting a top temperature of a quartz oscillator having the secondary temperature coefficient between the vicinity of an operating temperature range and outside of the operating range. CONSTITUTION:A quartz oscillator Q has a secondary temperature coefficient and is cut out so that the frequency is maximum near the upper limit T1 of the operating temperature range T0-T1. Since the oscillator Q has a positive temperature coefficient within the operating temperature range, the temperature compensation like a curve l2 can be made by using a temperature compensating capacitor having a positive temperature coefficient for either one or both of load capacitors C1 and C2. If the top temperature of the oscillator Q is set near the lower limit temperature T0, the temperature characteristics in the operating temperature range of the oscillator Q are negative. Thus, the temperature compensation like a curve l4 can be made by using a temperature compensating capacitor having a negative temperature coefficient.

Title: Polish method
Inventor: UENO YOSHIYUKI
IPC: B24B37/005
Filed: 1985-04-22
Abstract: PURPOSE:To make it possible to continuously carry out a highly efficient machining process and a finishing process with a high degree of efficiency, by forming several inclined grooves in the outer surface of a polisher opposing a workpiece such that the depth of each groove gradually varies in the direction of relative movement of the workpiece and the polisher. CONSTITUTION:Flat sections 103, inclined grooves 102 and slits 101 positioned between the former two are alternately and radially formed in the outer surface of a polisher 1. Further, when the polisher 1 is moved relative to a workpiece 2 in the direction (a), a negative pressure is effected between the polisher and the workpiece 2 due to the effect of a liquid polishing material 3 so that no substantial gap is obtained between the workpiece 2 and the polisher 1, thereby it is possible to carry out the polisher process with a relatively high matching pressure. Then, the polisher is moved in the direction (b) so that a positive pressure is effected due to the effect of the inclined grooves 102 and the polishing material 3, and therefore, the workpiece 2 is floated up from the polisher 1, thereby it is possible to carry out a light machining process. Thus, both rough polishing process and finishing process may be effectively made by one and the same machine.
