Inventor: SUZUKI TAKAYUKI
IPC: C04B38/06
Filed: 1987-07-22
Abstract: PURPOSE:To obtain a porous carbon material having excellent flexural strength, open cell ratio, etc., by mixing a liquid thermosetting polymer with a porosity- increasing material and hardened particle of an acrylic polymer or a carbonized particle produced by carbonizing said polymer particle, reacting the components under heating and carbonizing the product in a nonoxidizing atmosphere. CONSTITUTION:A liquid acrylic polymer is dripped into a hardener solution (e.g. ethylene glycol solution of p-toluenesulfonic acid) to obtain spherical hardened particles, which are, as necessary, further heated to obtain carbonized particles. The hardened particles or the carbonized particles are mixed together with a porosity-increasing material (e.g. polyethylene glycol or starch) to a liquid thermosetting polymer (e.g. phenolic polymer or furan polymer) and thermally reacted with each other to obtain a porous carbon precursor. The carbon precursor is carbonized in a non-oxidizing atmosphere to obtain a porous carbon material suitable as an electrode material, filter, etc.

Abstract: PURPOSE:To suppress the excessive increase in temperature of a metal ring in the longitudinal direction, to obtain stable sealing conditions and to form a high quality semiconductor device without poor airtightness, by contacting the side surface of a DIP type semiconductor device in the longitudinal direction with a stage. CONSTITUTION:A stage, on which a semiconductor device is mounted, is contacted with the side surface on the long side of the semiconductor device. By using this structure, sealing is performed. Namely, in the stage 3, two slits 7 are provided, so that a width of the semiconductor device to be mounted of, e.g., 300mil, 400mil or 600mil, is provided as an interval. Then, part of heat in the longitudinal direction of a metal ring 4 at the time of seam welding is dissipated through a ceramic substrate 1, outer terminals 2 and the stage 3. The excessive increase in temperature of the metal ring can be prevented. Meanwhile, since both end parts of the semiconductor device in the longitudinal direction is not contacted with the stage, the heat radiation is less. Therefore, the metal ring in the width direction of the semiconductor device is readily heated. In this structure, the dispersion in temperature of the metal ring is suppressed to a small degree, and the stable sealing conditions can be obtained.

Abstract: PURPOSE:To set the opening degree to a necessary value with high precision by converting the pulse electric current supplied into a solenoid to the smoothed voltage value and further digitizing the voltage value through the A/D conversion and adjusting the pulse width so that the pulse electric current is maintained to a prescribed value.
