IPC: G06Q10/10
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To select and print only information of high necessity automatically by decreasing the number of characters being printed in a row containing a table data of low frequency of occurrence when a line of cell data does not fall within a line of a print sheet. SOLUTION: When a cell data does not fall within a line of a print sheet, the row having lowest occurrence frequency of the number of characters in the cell data is retrieved for each row. When a plurality of such rows are found, the row having smallest difference in the number of characters is retrieved from the head table data (herein after referred to a data) and the second data in each row on a candidate group (herein after referred to a table) of the number of characters being printed of each sorted row. For the row thus retrieved, occurrence frequency of the number of characters in the head data on the table is added to occurrence frequency of the number of characters in the second data. Head data is then deleted and second and subsequent data are stored in the table.  Subsequently, the number of characters in all rows of data are added for the head data in each row on the table and a decision is made repeatedly whether it falls within one line or not (41-48).

Title: Dynamic damper
Inventor: MISHIMA MASAAKI
IPC: F16F15/126
Filed: 1989-05-17
Abstract: PURPOSE:To enable easily obtaining compact and light-weight design by applying the constitution wherein an elastic member for supporting a mass member is so made as to work for a supporting purpose mainly in a bending direction against the radial vibration of a rotary shaft. CONSTITUTION:When a harmful vibration is excited with the rotation of a drive shaft, the mass member 12 of a dynamic damper 1 having a natural frequency matched to the frequency of the harmful vibration resonates. The aforesaid natural frequency is basically determined with the mass of the mass member 12 and the spring constant of an elastic member 11. Then, the joint part of the leg part 111 and the main body part 112 of the elastic member 11 act as a support pint in the damper 1, thereby giving bending support like a kind of the cantilever wherein a load is acting on the contact part 121 of the mass member 12. As a result, the smaller is generally the spring constant when a distance from the load to the joint part is longer or the thickness of the main body part is smaller. As aforesaid, the damper 1 absorbs the vibration energy of the drive shaft due to the resonance of the mass member 12, thereby restraining the harmful vibration excited on the drive shaft.

In this case of an FM system, an input is fixed at a high level and the output of a gate circuit 23 is always fixed at a high level, as well. The output of a DFF 26 is delayed 1/64 f by a delay circuit constituted of a DFF and an inverter 28. This modulated output and the EMOR of 16 f are formed at a gate circuit 29 and thus, the AC bias signal inverted and/or synchronized by the modulated signal is gained.

Abstract: PURPOSE:To enable a height of a lead to be measured accurately by providing an allowable range of a height data of a lead protruding from a chip, eliminating a data outside the allowable range, and then obtaining a height of a lead from the data within the allowable range. CONSTITUTION:Laser beam is subjected to spot irradiation in a direction crossing a lead L and then a height data of a plurality of spot points is obtained and is stored 11. A data of an edge portion at both edges of the lead L and a data outside an allowable range (between upper and lower thresholds) out of this height data are cut. This cut is performed by an effective data extraction means 13. All data, where the number of data which are continuous within the allowable range is smaller than a specified number (minimum effective number), are cut. An average value X of remaining data is calculated 14 and a difference between each data which remained as the effective data and the value X is obtained. The average value X of the data where this difference is within a specified allowable range is obtained again. Then, a lead floating criterion means 15 judges whether the lead is floating or not and then allows a chip P to be mounted to a substrate 5 if the lead is floating.
