Title: Functional device
Inventor: YOSHIDA SHITOSHI
IPC: H03H9/02
Filed: 1995-01-13
Abstract: PURPOSE: To reduce the size of the functional device including a package-sealed type electronic component such as a crystal vibrator and maintain its performance by forming a circuit pattern on the external surface of the enclosure of the package-sealed type electronic component. CONSTITUTION: The circuit pattern 14a is formed on the external surface of the package (upper case 13) of the package type electronic component such as the crystal vibrator. Then electronic components 20 other than the package sealed type electronic component, such as an integrated circuit, a resistor, and a capacitor, are mounted on this circuit pattern 14a to form the function device such as the crystal vibrator 12. Thus, the package (upper case 13) of the package-sealed type electronic component serves as a PC substrate, so the PC substrate itself is unnecessary to not only reduce the size of the functional device on the whole, but also make principal elements such as a crystal piece 16 in the package-sealed type electronic component large in size, thereby maintaining and improving the quality and performance.

Title: Rolling method of strip
Inventor: HIRAI KOICHI
IPC: B21B1/22
Filed: 1985-01-17
Abstract: PURPOSE:To prevent an edge drop and to lengthen a roll life by rolling a strip at the position where upper and lower work rolls whose both ends are ground into tapers respectively are relatively moved in their axial directions and rolling the strip by changing reversely the roll positions before the roll-wears make the rolls unsuitable for rolling. CONSTITUTION:Both ends of each of upper and lower work rolls 1, 2 are tapered by grinding, and a strip 3 is rolled at the position where both rolls 1, 2 are relatively moved in their axial directions. Then the effect of two-step tapers is obtained, because the taper parts of rolls 1, 2 are shifted to the fight and left sides respectively and the relative positions with respect to the edges of a strip 3 are also shifted. Further, the positions of rolls 1, 2 which come into contact with the edge of strip 3 are changed by moving the rolls 1, 2 in the axial directions from the position A to the position B, and then the roll life is lengthened. Further, there causes no problems about the edge drop and profile of cross section of the strip 3 to be rolled before the roll rearrangement.
