Title: Production of antifogging transparent article
Inventor: MATSUZAKI YASUO
IPC: C08J7/06
Filed: 1985-09-04
Abstract: PURPOSE:To obtain a transparent article having good transparency and other properties and an excellent antifogging effect, by saponifying the surface of a transparent article with a strongly alkaline solution of sodium silicate and coating this surface with a surfactant. CONSTITUTION:A molding, sheet, film or the like of a transparent plastic such as cellulose acetate, propionate or butyrate is saponified by immersion in a strongly alkaline solution of sodium silicate. By this treatment, the interfacial tension to water is decreased through the formation of hydrophilic functional groups on the surface, so that coagulation of water drops on it can be prevented and at the same time the retention of a surfactant applied later can be improved. An immersion temperature in a range of 30-75 deg.C is the most suitable to perform effective treatment within a short time and not to damage the base material. An immersion time of 30-120min is desirable. The surface of the transparent plastic article saponified in this way is coated with a surfactant.

Title: Method for detecting at output stage of inverter
Inventor: HATTORI MOTONOBU
IPC: H02M7/48
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To detect the current of an inverter, while suppressing the cost increase in a circuit system and, at the same time, maintaining the system in a small size by calculating the phase current values of other two phases, based on the processed results of a sample hold circuit, A/D conversion circuit, etc., which process the phase current value of one phase at prescribed timing. SOLUTION: Resistors 7C and 7V are respectively connected to U- and V- phases and detect the quantities of currents flowing to transistors 5U and 5V or feedback diodes 6U and 6V. The detected analog quantities of the currents are sent to a sample hold circuit 10b and further to a register circuit 10d, through an A/D converter 10c and stored in a memory 10e. Of the U-, V-, and W-phase currents, the U- and V-phase currents are alternately detected, and when the U-phase current is detected, the V-phase current is subjected to approximate calculation. When on the contrary the V-phase current is detected, the U-phase current is subjected to approximate calculation. A three-phase bridge circuit 2 finds the phase current of W-phase from a relation between the current values of the three phases such that the sum of the current values becomes zero.

Title: Method for converting protocol for expressing polygon
Inventor: SUTEIIBUN JIEI HARINGUTON
IPC: G06T11/40
Filed: 1991-08-05
Abstract: PURPOSE: To efficiently convert the expression of a polygon from an odd- numbered turns of winding agreement to a non-zero turns of winding agreement without requiring the complicated evaluation of polygon sides in a graphic device. CONSTITUTION: The polygon is entered in a frame buffer by using a feature state. Then, a special scanning line is decided and a sign is given. The special scanning line is the one where the boundaries of the scanning lines and the polygons of a max. point and a min. point are bought into contact with a self contact area. The respective scanning lines are checked and the odd-numbered or even-numbered (down or up) sign is given to the entry term of the polygon on the scanning line. After that, the polygon is plotted again. At this time, the feature (temporary) state which is entered by a first pass is replaced with a down state or an up state. The entered state is a present direction value except the entry term on the special scanning line. At the time of the special scanning line, the entered state is given by an entry term with the sign inside the frame buffer.  The value becomes the present direction value as against the succeeding entry term.
