Title: Manufacturing method of minute electrode
Inventor: KIMOTO YASUO
IPC: B23H1/04
Filed: 1979-02-10
Abstract: PURPOSE:To efficiently and precisely manufacture a minute electrode in a short time, by alternately using two kinds, high and low consumption, of micro-spark erosion for reducing the size of the electrode. CONSTITUTION:A hole H1 is formed on a work S1 through low-tension and low- consumption micro-spark erosion with an electrode P. The machining electrode is then reversed to reduce the diameter of electrode P through high-tension and low-consumption micro-spark erosion by using the hole H1. The machining electrode is again reversed, that is, regaining the initial polarity, a hole H2 is formed on another work S2 through low-tension and low-consumption micro-spark erosion with the reduced electrode P1. Then the polarity is reversed again and the reduced electrode P1 is further reduced through high-tension and low-consumption micro- spark erosion. Likewise the two kinds of micro-spark erosion are repeated alternately to reduce the diameter of electrode step by step.

Title: Orthogonal transform coding method for picture data
Inventor: TANAKA YASUYUKI
IPC: H04N19/60
Filed: 1986-01-27
Abstract: PURPOSE:To improve the compression effect of picture data without adversely affecting the quality of a reproduction picture by recognizing an area where the absolute value of conversion data is below the prescribed value and zone- sampling only conversion data outside the said area. CONSTITUTION:The picture data (x) subjected to reprocessing is passed through an orthogonal transformation circuit 11, and subjected to two-dimensional orthogonal transformation. A conversion data (y) obtained in such a way is arrayed in all directions in sequential order, and encoded by an encoder 12. It extracts the conversion data (y) along an arc R, which uses the conversion data y(1, 1) as a center, at every block, and compares the absolute value of said data with a prescribed value (a). If even one value exceeds the prescribed value (a) in the area with a substantially small diameter given to the arc R, the comparison is stopped. Then the arc R is increased to do the same operation. Thus only the conversion data outside the area is zone-sampled to encode.

Abstract: PROBLEM TO BE SOLVED: To ensure stabilized driving of a magnetostrictive element by providing a circuit for interrupting a high voltage being induced instantaneously through switching operation of a power switch, and a circuit for eliminating a residual voltage at a storage circuit part upon power interruption. SOLUTION: When a power supply voltage is applied to a silicon rectifier Q1, a resistor R1 and a capacitor C2 interrupt a high voltage being induced instantaneously upon switching and the positive half period voltage rectified through a diode D1 is stored in a capacitor C1. The - side voltage divided through a transformer T1 is rectified through a diode 3 and a trigger signal is applied to the silicon control rectifier Q1. Consequently, the rectifier Q1 is turned on and a magnetostrictive element T2 is driven by the voltage of the capacitor C2. When a power switch SW is turned off, the rectifier Q1 is turned off to interrupt the voltage being applied to the magnetostrictive element T2 and the residual voltage of the capacitor C1 is eliminated through a resistor r5.

Filed: 1998-01-12
Abstract: PROBLEM TO BE SOLVED: To inhibit generation of residue, and thereby to prevent product contamination and enable stable operation for an extended period by making a pigment concentration in a thermoplastic resin of a surface layer lower than that of a thermoplastic resin of an inner layer. SOLUTION: A pigment concentration in a thermoplastic resin for surface layer is made lower than that of a thermoplastic resin for inner layer for co- extruding. By making the pigment concentration in a layer contacting with a die (the surface layer) lower than that of a layer not contacting to the die (the inner layer), generation of residue can be inhibited considerably compared with co-extruding of a resin having a uniform pigment concentration throughout. At this time, the pigment concentration in the thermoplastic resin for surface layer is preferably 7 pts.wt. or lower, specially 5 pts.wt. or lower with respect to 100 pts.wt. thermoplastic resin. When it is over the above range, the residue is liable to generate.  On the other hand, an upper limit of the pigment concentration in the the thermoplastic resin for inner layer is normally 40 pts.wt., preferably 30 pts.wt., and more preferably 20 pts.wt. with respect to 100 pts.wt. thermoplastic resin.

Abstract: PURPOSE:To realize a multi-access system having the efficiency approximately equal to a token pass system by adding plural control parameters to the CSMA/ CD system to control the access quantity based on the information obtained newly from a channel. CONSTITUTION:A control part 12 has a normal operation of a normal CSMA/CD system when a gate 13 is opened and then has an operation same as the CSMA/ CD system obtained in a transmission mode of channel when the gate 13 is closed. A counter 14 uses M as a divisor and counts up every fixed period of time in case no received signal is delivered from a transmitting/receiving part 11 and no collision signal is delivered. While the counter 14 performs a count-up operation after the received signals end if these signals exist. An arithmetic circuit 15 reads out a parameter corresponding to the value of the counter among M units of parameters stored in a memory circuit 16 and then sends it to the gate 13. Thus the gate 13 is opened. Then the circuit 15 calculates a specific equation in accordance with the output of the part 11 and then replaces the parameter.
