Title: Antistatic and antifogging strippable clear coating
Inventor: TOGO SHIZUO
IPC: C08K5/10
Filed: 1985-07-16
Abstract: PURPOSE:To provide the titled coating which forms an antistatic and anti- fogging coating film temporarily for surface protection of an object, by dissolving polyvinyl butyral resin, plasticizer and phosphoric ester type surfactant in an organic solvent. CONSTITUTION:The coating is prepared by dissolving in an organic solvent (a) 100pts.wt. resin consisting mainly of polyvinyl butyral resin, (b) 30-150pts.wt. plasticizer and (c) 1-5pts.wt. phosphoric ester type surfactant. When an average degree of polymerization of the polyvinyl butyral resin is below 250, it is difficult to obtain a coating film with sufficient strength and strip it as a continuous film, while when it exceeds 10,000, the viscosity of coating soln. becomes too high for coating operation. When the surfactant is added in less then 1pt.wt., sufficient anti-fogging and antistatic properties are unobtainable, while when it is added in more than 5pts.wt., the moisture and water resistance of coating film is lowered.

Title: Charging circuit of secondary battery for portable terminal device
Inventor: MURAKAMI YUJIRO
IPC: G06F1/26
Filed: 1996-06-18
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption by equipping a charging circuit with a constant current circuit which supplies the minimum charge current to compensate the action of CPU and a first current path which supplies a large current, with its conductivity controlled when a secondary battery is charged to specified voltage. SOLUTION: A changing 10 supplies a minimum constant current required to enable the action of CPU 20 immediately after start of charge. Next, at the point of time when the charging voltage goes up to the voltage by which the dive of the CPU 20 becomes possible, the CPU 20 controls the charge current 10 so as to increase the supply current to the secondary battery 1. Accordingly, it follows that a great charging current does not flow to the secondary battery 1 until the CPU 20 drives it, even if it is supplied with DC power 11. Hereby, in case that there is fault in the secondary battery 1, the charging circuit 10 can prevent the accident caused by overcurrents and drop the power consumption.

Title: Numerical controller
Inventor: NAMIKADO SHIGEKI
IPC: G05B19/4155
Filed: 1987-06-26
Abstract: PURPOSE:To realize the simple processing with a numerical controller without producing the miscutting, the resetting of patterns, etc., by separating a pattern into the closed areas when the intersecting pints are included in the pattern and checking the presence or absence of foul tags as well as the turning direction of the pattern for each closed area to decide a valid or invalid state. CONSTITUTION:The turning direction of the final input shape 8 is obtained and a tool path pattern 9 is produced against the shape 8 to check the presence or absence of intersecting points of the pattern 9. If intersecting points C1 and C2 are detected, the pattern 9 is separated into closed areas I, II and III. Then it is checked whether a foul tag is added to each pattern element of the area I. If no foul tag is included in the area I, the turning direction of the area I is decided. Thus the shape of a valid closed area is obtained since the turning direction of the pattern 9 is equal to that (clockwise CW) of the shape 8. The area II includes no foul tag and has its turning direction (counterclockwise CCW) opposite to that of the shape 8. Thus the area II is decided invalid and not delivered. While the area III is valid like the area I. As a result, both areas I and III are decided valid and delivered in this example.
