IPC: G03F7/20
Filed: 1996-07-23
Abstract: PROBLEM TO BE SOLVED: To provide an alignment method for alignment marks which can improve overlapping precision of a plurality of chip positions and throughput in a lithography process. SOLUTION: Only one couple of an X direction alignment mark 13 and a Y direction alignment mark 14 exists in chips 1, 2 which form an exposure field. The positions of the alignment marks 13, 14 are in the shortest distance from the exposure axis of an aligner, i.e., the central axis of an exposure filed.

Abstract: PURPOSE:To obtain a low cost thermal head having good workability, by arranging a common electrode in U-shape so as to contact with three sides of an insulating substrate, thereby forming the common electrode upto the planar section of the rear face of the insulating substrate through endface sections for forming three sides of the insulating substrate. CONSTITUTION:A common electrode 1c is arranged in U-shape so as to contact with three sides of an insulating substrate 1a thus forming the common electrode 1c upto the planar section of the rear face of the insulating substrate 1a through endface sections for forming three sides of the insulating substrate 1a. Consequently, the width of conductor of the common electrode 1c can be enlarged and the resistance of the common electrode section can be reduced sufficiently. Since the common electrode 1c can be connected to an external circuit by soldering lead wires 6 led from the opposite end sections of the U-shaped common electrode 1c disposed on a same plane formed with heating elements 1b to a printed board 4, complex comb-type common electrode lead wires and an electrode cover are not required, and since the soldering portions can be taken out from the opposite end sections, the assembling workability is improved. Furthermore, the size of a heating element substrate 1 can be reduced because the common electrode is soldered to the opposite end sections of the heating element substrate 1.

IPC: A47F3/00
Filed: 1991-04-04
Abstract: PURPOSE:To retain fresh flower for a long time and enjoy the appearance and fragrance, by providing a freely rotatable base seat in an appreciation case and also a vent hole freely opened or closed. CONSTITUTION:A base sheet 3 is provided in the base to support a case body 1 in order to place a plant. The base seat 3 is freely rotated by an electrical motor connected to an electric source through a switch 4.

If the cover 6 of vent hole 5 is opened when required, fragrant air filled in the inside is emitted from the air vent 5. And when the cover is closed, the fragrance is cut off. In this way, since the fragrance filled in the inside is emitted intensively, one can enjoy effectively and sufficiently the fragrance. And since the air around the leaves is moved, it helps normally grow the plants.

Abstract: PROBLEM TO BE SOLVED: To reduce the effect of circuit impedance by feeding currents with the polarity opposite to that of the currents fed to one end of the loads of tested LSIs from DC voltage/current generating circuits to the other end of the loads. SOLUTION: HF amplifiers 7a-7d in DC voltage/current generating circuits 6a-6d receive electric power from a power circuit 1v and feed a set voltage or a current to loads 5a-5d respectively. The voltages generated across both ends of the loads 5a-5d are fed back to the H, L side output monitor terminals of the DC voltage/current generating circuits 6a-6d respectively, and the DC voltage/current generating circuits 6a-6d control the outputs of the HF amplifiers 7a-7d to the voltage values required on the load side while monitoring these voltages. Output current monitor circuits 8a-8d monitor the output currents of the HF amplifiers 7a-7d, control LF amplifiers 9a-9d, and output the currents with the polarity opposite to that of the monitored output current values.  All output currents from the HF amplifiers 7a-7d flow into the LF amplifiers 9a-9d, and the effect of circuit impedance can be reduced.
