IPC: G06F3/03
Filed: 1984-11-30
Abstract: PURPOSE:To detect a coordinate with high accuracy independently of an external force exerted to an input panel by using a voltage proportional to the quantity of the external force applied to an input panel as a reference voltage of an A/D converter. CONSTITUTION:When an external force is applied to the input panel, resistance voltage converters 2a-2d output voltages fa-fd proportional to a weight through the resistance change of a strain sensor of weight detectors 12a-12d. When an output F of an adder 3 exceeds an output fmin of a reference voltage generator 5, the voltages fa-fd are converted into a digital quantity by A/D converters 6a-6d while using the voltage F as a reference. Suppose that the reference voltage changes proportional to the input voltage, that is, when the input voltage is 1V, the reference voltage is 5V and when the input voltage is 0.1V, the reference voltage is 0.5V, then the error of the outputted digital quantity is 5%, which is constant to any input voltage. The outputted digital quantity in this case is unchanged and although the input voltage. The outputted digital quantity in this case is unchanged and although the input voltage cannot be known from the output digital quantity, it is no problem because the weight can be a relative value. Further, an accuracy of + or -3% is obtained within the range of external force, 50g-1kg.

Title: Betting ticket reader having disused ticket processing function
Inventor: MIYAMOTO MASASHI
IPC: G06Q50/00
Filed: 1998-09-08
Abstract: PROBLEM TO BE SOLVED: To facilitate the follow-up surveys of disused betting tickets by performing the ticket disuse processing so that the bar codes of the disused tickets cannot be read after the hit or subtraction processing is performed. SOLUTION: An inserted betting ticket is carried to a bar code reading sensor 2 which reads the bar code of the ticket. If the betting ticket is already processed, its bar code is partly painted out and cannot be read. Thus, a betting ticket reader 1 decides a processed betting ticket and returns it to a ticket slit. If a processed betting ticket is not painted out, its bar code is decoded and the decoded contents are sent to a host system. The host system performs the hit or subtraction processing and sends the answer data to the reader 1. The reader 1 decodes the received answer data to return the betting ticket to the ticket slit if the continuation of its processing is impossible and to perform the ticket disuse processing via a disused ticket print head 3 if the continuation of its processing is possible.  Then the reader 1 stores the betting ticket in its internal stacker and stops the drive of a motor 4.

Title: Interrupt processing system for production system
Inventor: KAWABE MITSUNORI
IPC: G06F9/44
Filed: 1988-10-07
Abstract: PURPOSE:To enable another inference process to be started during one inference process and the current inference process to be corrected by adding an interrupt detection part to the inference engine of a production system, and generating a working memory element corresponding to an interrupt and firing an interrupt process rule. CONSTITUTION:The interrupt detection part is added behind the execution part of the inference engine, which detects an interrupt in the end of each cycle of collation, conflict elimination, and execution. In a next inference cycle, the working memory element corresponding to the interrupt is the latest element, so the interrupt process rule having this interrupt element as a condition part is selected by the conflict elimination and executed. The interrupt process rule is fired, and then the current inference is interrupted, so that the inference of an interrupt process is started. At this time, the working memory element that the restarted inference process refers to is altered in the interrupt process rule. Consequently, the inference process after the restart can be corrected.
