Title: Manufacture of electrical laminate
Inventor: SATO KOJI
IPC: H05K1/03
Filed: 1988-04-15
Abstract: PURPOSE:To prevent generation of a crack at the time of boring processing of a through hole, by a method wherein at the time of heating, pressurization and molding of a plurality of metallic sheets provided with through holes and piled up through prepreg, a matter whose tan delta of viscoelastic spectrum at the glass transition point of a cured matter is at least a specific value is used as resin infiltrated into the prepreg. CONSTITUTION:A plurality of metallic sheets 2 into which through holes 1 are provided are piled up through prepreg 3, the same is heated, pressurized and molded and resin infiltrated into the prepreg 3 is cured. The metallic sheets 2 each are stuck through lamination, the resin infiltrated into the prepreg 3 is flowed into the through holes 1 of the metallic sheets 2 for filling and cured. At the time of performance of boring processing of a through hole 5 at a part of the resin 4 within the through hole 1, a matter whose tan delta of viscoelastic spectrum at the glass transition point of a cured matter is at least 0.1 is used as the resin infiltrated into the prepreg.

Title: Full disc type brake friction plate
Inventor: SAKAGAMI MASATAKE
IPC: F16D65/12
Filed: 1992-04-14
Abstract: PURPOSE:To solve the problem with a full disc type brake friction plate that its friction surface is so close that powder formed by abrasion is likely to remain inside a frictional area, causing torque vibration and accelerating abrasion. CONSTITUTION:A groove 2 is provided in the friction surface 1 of a friction plate in such a manner as to cross the surface. The groove 2 has its end portions open to the inner and outer peripheral surfaces of the friction plate. Powder formed by abrasion tends to move circumferentially on the friction surface and is therefore trapped in the groove 2 during a move and is moved within the groove by centrifugal forces and microvibration during braking and then released to the outside. Therefore, the possibility of stick-slip that could cause torque vibration is reduced and the possibility of the powder attacking the friction surface and thus accelerating abrasion is eliminated.
