摘要： PROBLEM TO BE SOLVED: To provide a system for calculating an index, by which a rule of transaction work is evaluated from the viewpoint of the degree of violation, by means of a computer. SOLUTION: For every event of transaction, a score is given to each of rules according to transaction contents. When attention is paid not only to transaction violation but also to a warning numeric value set for each rule, transaction exceeds the warning numeric value is reflected as warned transaction to an evaluation score. When weights are assigned to the actually violating transaction and the warned transaction, the violating transaction further affects the evaluation score. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an image pickup device in which an optical zoom means and an electronic zoom means are interlocked smoothly by changing an interlocking start position of the optical zoom means and the electronic zoom means depending on a mechanical play of the optical zoom calculated by a play calculation means. SOLUTION: A mechanical play of a gear 105 connecting a zoom lens 102 and a stepping motor 106 is stored in advance in a play memory 10A. A play calculation circuit 109 calculates a mechanical play at a wide angle position and a telescopic position based on the play signal a117 from the play memory 10A and an optical zoom control signal 112 from an optical zoom control circuit 107 to provide the output of a play signal b115. An electronic zoom control circuit 108 calculates an error between a physical lens position and a calculated lens position based on the play signal b115 to revise the interlocking start position between the optical zoom and the electronic zoom depending on the error. Thus, the optical zoom and the electronic zoom are smoothly interlocked.

摘要： PURPOSE:To largely reduce the retrieving time at the time of starting reproduction and switching the reproduction mode and to ensure acquisition of an optimum tracking condition with high precision. CONSTITUTION:Delay reference signal DREF issued from a digital delay means 11 gives a reference signal for tracking control. For example, at the time of starting reproduction, the delay amount of the digital delay means 11 is roughly changed over a wide range to detect the delay amount of the digital delay means 11 which maximizes the envelope level of the reproduced signals detected by a sampling circuit 14. Succeedingly, the delay amount of the digital delay means 11 is finely changed over a narrow range including this detected delay amount to obtain the delay amount of the digital delay means 11 giving the maximum envelope level within this range as the delay amount in an optimum tracking condition. Here, the rough retrieval is designed to start from the delay time close to that when the maximum reproduction output level is obtainable so that fine retrieval is immediately started.

摘要： PURPOSE:To high speed parallel computation even at the time of using a finite element method by dividing the whole analytical area into the optimum number of partial areas corresponding to the number of CPUs and almost uniforming the numbers of nodes in respective areas. CONSTITUTION:A shape input device 1a inputs the shape of an area to be analyzed and divides the area into fine meshes and a renumbering device 2a inputs the shape data of the divided meshes from the device 1a and divides the data into partial areas necessary for parallel computation. A parallel computing device 3a inputs the divided data from the device 2a and executes paralle computation. A corner point whose connection to other nodes is small is found out from nodes constituting the meshes, all the nodes around the corner point are divided into groups and the number of groups is allowed to match/with the number of CPUs. One CPU is allocated to each group and respective CPUs are operated in parallel. Consequently parallel computation in respective partial areas can be almost uniformly executed even in the case of using the finite element method.

摘要： PURPOSE:To realize a stable and speedy transient performance with few overshooting in the transient state of a phase control system only by equivalently increasing the sample rate of a capstan phase system by a signal. CONSTITUTION:A speed control output of a speed control block 6 and a speed control output delayed in the amount of one cycle of CFG by a delay circuit 12 are integrated, and to this integrated output, a tracking control output of a tracking control block 9 is added. On this addition of the integrated output and tracking control output, the integrated output is initialized to a prescribed value by an integrated value control block 11 based on a tracking control timing signal which is outputted from the tracking control block 9 for every time the tracking control is performed.
