Title: Spread draw line deciding method for press processing
Inventor: TSUTAMORI HIDEO
IPC: G06F19/00
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To decide a spread draw line faster at a press processing while maintaining a finishing accuracy of a pressed compound. SOLUTION: An outer shape of a material after completion of a processing is obtained by a forming simulation based on a temporarily decided spread draw line (S12). A given process is repeated until the difference between the outer shape of the raw material after completion of the press processing and an objected shape reaches within acceptable tolerance.(S18) Namely, an outer shape of the raw material after completion of a press processing is obtained based on an amended spread draw line, the objected shape is mapped so as to amend the spread draw line (S14, S16). A finishing accuracy of the press compact can thus be maintained. At this time, the amended spread draw line is decided as the spread draw line for the press processing (S19).  Since computing and the like of the forming simulation and a mapping of the objected shape are all carried out by a computer, the spread draw line of the press processing can be decided faster than before.

Title: Copper-clad insulating sheet
Inventor: HARUTA YOICHI
IPC: H05K1/03
Filed: 1993-09-06
Abstract: PURPOSE:To enables the manufacture of multilayer printed wiring board having blind holes of an infinitesimal diameter, excellent in mass-productivity, by semicuring or fully curing a first resin composition layer, except for areas where via holes are to be formed, by the irradiation of an active energy beam. CONSTITUTION:The resin side of a copper-clad insulating sheet is laminated on an insulating substrate 5 having a copper wiring pattern 4 on its surface. A second resin composition layer 2, high in heating fluidity, almost entirely flows away from the top of the copper wiring pattern 4 on the insulating substrate 5, and a first resin composition layer is left on the copper wiring pattern 4. Areas of the resin composition layer that has been exposed by forming microminiature holes in the surface copper foil and is to be subjected to alkali dissolution, are those which has not been cured by an active energy beam. Even if they are in the first resin composition layer, therefore, areas semicured or fully cured, by the irradiation of an active energy beam will not be dissolved in alkali. Thus the diameter of blind holes is determined by that of resin compositions that have not been subjected to the active energy beams irradiation.

IPC: B21D11/20
Filed: 1993-09-07
Abstract: PURPOSE:To execute the bending work of metal plate by linear heating without depending on a skilled worker. CONSTITUTION:After the geometrical information of an initial shape and objective shape is inputted (step 1), the mesh dividing of finite element method on the initial shape is executed (step 2), the divided shape is mapped on the objective shape (step 3).

By obtaining the quantitative relationship between heating condition and generated specific strain, the generated specific strain at given heating condition is obtained (step 6). As a heating device is stopped at the position specified by the heating method obtained in the step 5, 6 and heating is executed continuously for a certain time, the specific strain is imparted, bending the plate to the objective shape step 7, 8, 9).

Abstract: PURPOSE:To prevent the discharge voltage change caused by the ambient temperature change by detecting and feeding back the change of the current flowing in a cathode discharge tube, and feeding a constant current to the transformer secondary winding with the output in response to it. CONSTITUTION:The current I flowing in a cathode discharge tube L is detected by a current detecting circuit 3 connected in series to the discharge tube L, and this detection quantity (change quantity due to the external condition change such as temperature) is fed back to a voltage control circuit 1. The circuit 1 compares the feedback quantity with the reference voltage Vref, applies the result to a transformer T via a switching circuit 2, and generates voltage V so that the preset current I in the secondary winding of a transformer T is made constant. The intensity of multiple discharge tubes can be stabilized. The reference voltage Vref is made the same for each cathode discharge tube driving circuit. The feedback quantity can be changed when only the reference voltage Vref is changed, and the intensity for individual tubes can be concurrently changed by the same quantity or at the same rate.

Filed: 1987-09-30
Abstract: PURPOSE:To output reproducing signals from plural recording media as the continuous signals by delaying and outputting the reproducing signals from the plural recording media while taking the exchanging time of the recording media into consideration. CONSTITUTION:A reproducing device 4 reproduces reproducing subjects while automatically switching them successively in the order of first-N-th recording media, and outputs the reproducing signals PB to the N-th input terminal TI2N of a delay circuit 5 and a switching circuit 6.
