Title: Drive circuit for thermal head
Inventor: KOMATA TAKASHI
IPC: B41J2/355
Filed: 1987-12-16
Abstract: PURPOSE:To enable stable and high-quality printing at high speed even when high application power is set for a thermal head by providing a means to control an energization period per a single line of thermal head and a means to generate a period for energization suspension during the heating of a single line, in a thermal head drive circuit. CONSTITUTION:An energization pulse generation circuit 4 controls the energization to a thermal head 7 only for a time preset per gradation for expression of density gradation. A suspension time generating circuit 5 controls the suspension of energization to the thermal head 7 only for a time preset per gradation. The above-mentioned two circuits are used alternately or continuously and the energization and its suspension are repeated during the heating period of a single dot on the thermal head. The thermal head 7 is cooled to prevent overheating by providing a plurality of times for energization suspension during a heating period. Consequently, high-speed printing is performed by increasing an application power to the thermal head. Especially, high-quality and sharp- image print can be obtained in a short time by using sublimating dye for a thermal transfer full-color printer.

Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy of control of the thickness of a plating layer, at the time of continuous aluminum plating, by performing plating operation on the basis of a prediction equation for the thickness of a plating layer to be formed, obtained by analyzing the effect of operation factors on the rate of alloy layer forming reaction from the correlation between the elapsed time, from the point of time when a steel sheet as a base material is introduced into a plating bath to the completion of solidification of the resultant plating layer on the pulled-up steel sheet, and the formed-layer thickness of an alloy layer. SOLUTION: Plating is performed by introducing a steel sheet as a base material into a molten Al-Si bath containing 3-13wt.% Si and held at a temp. in the range between the melting point and (the melting point +70 deg.C). After the formation of a plating layer, forced cooling is applied by means of a cooling device disposed above the bath. At this time, the thickness of an Fe-Si-Al alloy layer formed in the interface between the steel sheet as a base material and the plating layer is computed by prediction equation A1 or A2, and, based on the amount of displacement between the resultant predicted layer thickness τC and the desired layer thickness, the output ratio of cooling velocity above the plating bath, the travel speed of the steel sheet, or the temp. of the plating bath is regulated, by which the thickness of the alloy layer formed can be controlled to the desired thickness.

When the compressing part 24 having the elliptical shape is compressed to the cross section of the hexagonal shape, the inner- and outer-layer strands of the existing line A are crushed. Therefore, the corroded and oxidized films on the surfaces of the inner- and outer-layer stands can be removed. Thus, the current from the inner- layer strand can be made to flow into the branched clamp 10. Therefore, the abnormal heating of the connecting port can be prevented.

Title: Coaster of cup or the like
Inventor: SAKURAI SABURO
IPC: A47G23/03
Filed: 1994-11-29
Abstract: PURPOSE: To fit an inside surface to the peripheral surface of a cup and to prevent the hand from being wet with water by molding a cylindrical body part to a corrugated shape, thereby making the part freely expandable and contractable in a diametral direction. CONSTITUTION: Many projecting line parts b1 , b2 along the longitudinal direction of the cylindrical body part 1 are formed on the inside surface side and outside surface side of the cylindrical body part 1. The height(h) and pitch(p) of the corrugations of the corrugated sheet of the cylindrical body part 1 are determined according to the expansion width in the diametral direction of the cylindrical body part 1. The coaster X is expanded in the outside diameter before mounting. As a result, the cylindrical body part 1 is formed to the state adequately fittable to the peripheral surface of the cup. The cylindrical body part of one side is applicable to cups, etc., of various sizes and shapes. The cylindrical body part does not easily dislodge from the cups, etc. The water condensed on the surfaces of the cups, etc., is easily absorbed.  Since the cylindrical body part 1 is formed of the corrugated sheet, the cylindrical body part has adequate strength in spite of paper and, therefore, even if the water is absorbed in the cylindrical body part mounted at the cup A, the cylindrical body part is hardly collapsible in the shape and the adequate use for a relatively long time is possible.
