IPC: B65H31/00
Filed: 1987-11-05
Abstract: PURPOSE:To confirm the number of actually needed printing papers and the number of improper printing papers in a printing process, by providing a main counter for counting the actually needed printing and a sub-counter for counting the improper printing paper and changing over counting operation between the sub-counter and the main counter in connection with a temporary paper receiving device. CONSTITUTION:An operating handle 3 is kept horizontal before printing paper is printed in a proper state to hold a front contact plate 11 to a vertical state and a support plate is retracted to release operation and printing is started. In this state, a connection arm 13 is in a horizontal direction and a limit switch 5 is not pressed and only a sub-counter C2 performs counting. The handle 3 is pushed down at the point of time when a printing state becomes stable and the proper printing paper is delivered to horizontally open the front contact plate 11 and the support plate 2 is allowed to protrude above a delivery paper pile (a) to temporarily receive the proper printing paper. At this time, the connection point of connection arms 12, 13 moves upwardly to operate the limit switch 5 and the counting by the sub-counter is changed over to the counting of the number of the proper printing papers by a main counter C1.

Abstract: PURPOSE:To make a correct demodulation possible even though a phase deviation occurs in PLL circuit clock pulses by latching pulse train signals with a second clock pulse which consists of an integer multiple frequency and then relatching with a first clock pulse. CONSTITUTION:A PLL circuit generates first PLL clocks (f) which are phase synchronized to peak pulses from a peak detecting circuit and second PLL clocks (e) which have a frequency that is twice the frequency of the clocks (f) and transmits them to a demodulating circuit. At the demodulating circuit, ampsenses A and B are latched by the clocks (e) at a JK-FF 202 and the latched output signals (g) are relatched by the clocks (f) at later stages D-FF 214 and 203. Thus, a correct latch is accomplished by small period clocks (e) even though a small amount of phase deviation occurs in the clocks (f).

Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To prevent an optical characteristic from deteriorating by providing a titanium oxide film on the surface of the part of members that constitute a lighting system. SOLUTION: For a lighting system 2, projection optical system 4, inspecting equipment 9, alignment system 6, etc., optical members (optical elements) such as lenses, mirrors, prisms, analytical optical elements (binary optics elements, BO system elements) are used. A thin titanium oxide (TiO2 ) film is provided on the surface of the part of such optical members and on the part of the surface of a holding member that holds the optical members and on the part of the surface that constitutes a tube. Thus, even when the manufacture of a semiconductor device is performed for long periods, the surface of each member prevented effectively from being contaminated, due to the adhesion of particles and the materials in the air that cause contamination. Titanium oxide absorbs ultraviolet rays, especially far-ultraviolet rays and gives effects as an optical semiconductor. Typical effects given as the optical semiconductor are an antistatic effect due to conduction and a decomposing action as the optical medium.
