Filed: 1998-01-09
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous ticket examining processing by identifying the ticket of an owner himself and the ticket of another person by providing a read means for reading owner specification information recorded on the respective plural tickets utilized while being combined. SOLUTION: A CPU 21 reads identification information such as passenger data and ID data recorded on the first inserted train ticket through a magnetic ticket processing mechanism 24 and stores these thicket data in a RAM 23 for collation and when the second train ticket is inserted, its data are similarly stored in the RAM 23. At such a time, the CPU 21 identifies whether both tickets are owned by the same passenger or not. For example, the ID data of the first ticket are collated and checked with the ID data of the second ticket, it is collated and confirmed both tickets are owned by the same ticket user and when the passenger data are discriminated effective, passage is permitted. Thus, even when the ticket of another person or any unwanted ticket is mixed, no trouble occurs and the ticket check can be normally utilized.  Therefore, smooth ticket check is promoted and automatic ticket processing efficiency is improved.

IPC: B41J2/05
Filed: 1987-01-23
Abstract: PURPOSE:To obtain an ink jet head capable of line recording, showing a small impact force exerted by an ink and having a long useful life, by setting the width of a slit-shaped nozzle hole to be smaller than the width of a heat generating element, and setting the spacing between the nozzle bole and the element to be smaller than the width of the element. CONSTITUTION:Heat generating elements 16 are provided in a substrate 11, and electrodes 12 are led out from the elements. A slit-shaped nozzle hole 14 is disposed on the upper side of the elements, and fixed to leave a predetermined spacing between it and the elements by spacers 17 serving also as ink chamber walls. The width of the nozzle hole and the spacing between a nozzle plate and the elements are set to be smaller than the length of the element. When a current pulse is applied to the element, small bubbles 21 are generated, and grow into a bubble 23. The bubble pushes an ink to the exterior of the nozzle, and the ink becomes bag-shaped. When the current pulse is cut off, the ink starts contracting to form an ink droplet 28. A meniscus 29 is formed at the slit part, and a recessed part of an ink layer is supplied with the ink due to the surface tension of the ink. Thus, jetting of the ink droplet is completed, and the jetting to follow can be performed.

Title: Error correcting method
Inventor: TOMIZAWA SHINICHIRO
IPC: H03M13/00
Filed: 1986-01-27
Abstract: PURPOSE:To correct not only a two-symbol error certainly but a three-symbol error by estimating error on a basis of syndromes with respect to an internal code and an external code and correcting error only when both codes are coincide with respect to estimated error and error cannot be corrected. CONSTITUTION:When 4 symbols are fetched, two syndromes of a code Q are completed and are transferred to an error position generating circuit 9 from a RAM 3; and if error exists, operation is performed to check whether it can be corrected or not. If there is not contradiction between internal and external codes with respect to error and error can be corrected, the position and the range of error are operated and held. If there is contradiction and error can be corrected, similar operation is performed. When correction is determined, error is sent to an error correcting circuit 8 and is corrected. If there is contradiction between internal and external codes with respect to error, correction is performed with one code and the validity is discriminated with the other. Thus, not only two-symbol error is corrected certainly but also the probability of erroneous correction for three-symbol error is suppressed.
