Title: Electronic musical instrument
Inventor: MATSUSHIMA TADASHI
IPC: G10H5/00
Filed: 1987-08-13
Abstract: PURPOSE: To prevent the reduction of sound quality by calculating and synthesizing musical sound waveforms and mutually adding synthesized musical sound waveforms, and at the time of detecting an overflow based upon the added result, switching the added value to a previously set maximum value and outputting the maximum value. CONSTITUTION: Musical sound waveforms are calculated and synthesized, the synthesized musical sound waveforms are mutually added by an adder 11, and at the time of detecting an overflow based upon the added result, the added value is switched to the previously set maximum value and the maximum value is outputted. Namely, the upper limit or lower limit of the waveform level of the added waveform is cut off by a limiter circuit 20 to flatten the waveform. Since a sharp part is generated on the cut part, a slight noise component is generated. However the noise component is remarkably smaller than distortion generated due to the overflow and an original sound is not lost, a margine can be left in sound generation. Consequently, a quality musical sound waveform reduced at its distortion can be outputted.

Title: Manufacture of printed-wiring board material
Inventor: HORIBATA SOICHI
IPC: H05K3/02
Filed: 1985-09-12
Abstract: PURPOSE:To prevent voids and craters from developing, enhance edgewise insulation resistance and at the same time peel strength of metal foil by a method wherein base material is impregnated with resin in an atmosphere, the absolute humidity of which is below a specified value. CONSTITUTION:Base material is impregnated with resin in the atmosphere, the absolute humidity of which is 0.015kg/m<3>. As a result, the edgewise insulation resistance of the resultant base material is high and neither void in its interior nor crater in its surface exists. In addition, the curing characteristics such as the gel time, the maximum exothermic temperature and the like of the resin during the manufacture of a board material are also improved. Especially as for a board material, to the surface of which metal foil is laminated by molding, no shrinkage mark develops in the metal foil and accordingly the peel strength of the metal foil is enhanced. Furthermore, the base material is preferably impregnated with the resin in such a manner that the resin content of the resultant printed-wiring board material lies within the range of 30-80wt%. If the resin content is less than 30wt%, blister tends to develop in the base material during the curing of the resin. If the resin content is more than 80wt%, the base material warps in a large scale when it is etched.
