Particulate novolac resins and aqueous dispersions are produced by condensing phenol with aldehyde using acid catalysis. Following neutralization, particulate novolac resin is formed by adding protective colloid to the aqueous mixture. Resin particle isolation can be aided by dephenolation.

The process involves the use of an additive consisting of an alkali metal or alkaline-earth metal metaborate. Manufacture of creep-free prepegs by using solutions of phenolic resins and reinforcements: glass fibres, carbon fabric.

Polyester-polysiloxane block copolymers for dental uses are disclosed as low modulus thermoplastic elastomers. The copolymers comprise polycaprolactone residues and poly(dimethylsiloxane) alpha , omega -diol residues which are linked by ether bonds. The compounds exhibit the property of plasticity by heating and the property of original rubber elasticity by cooling again to room temperature.

PURPOSE:To reduce the movable parts while reducing the particle production by a method wherein a wafer can be carried from a standby chamber to a reaction chamber only by controlling the forward on backward motion of an arm to be held or released by electrical control. CONSTITUTION:An arm carrier 5 is provided in a standby chamber 4 connected to a reaction chamber 2 through the intermediary of a d...

PURPOSE:To prevent the deposition of silicon on an ohmic contact part, by bringing other silicon region into contact with an Al wiring, and making other silicon region absorb the excess silicon due to unevenness in the Al wiring. CONSTITUTION:A polysilicon layer 6 is formed on the whole surface of an insulation layer 2 before a hole for an ohmic contact 4 is not yet opened thereon. Next, a hole is...

PURPOSE:To improve high-frequency characteristics, by providing a buffer layer with a projection, forming a recess in an active layer located on this projection and providing a gate on the bottom face of this recess. CONSTITUTION:A projection 5 is provided on the surface of a GaAs substrate 2. Then an undoped GaAs buffer layer 3 and an Ai doped N-type GaAs active layer 4 are grown sequentially on ...

PURPOSE:To signalize a graphic easily without fail by inputting a signal concerning the density of the graphic at the coordinate position by an optical detecting means to a data processing device, and preparing an image data to signalize the graphic based upon these input signals. CONSTITUTION:A document 2 to display the graphic is provided on a tablet 1, the part to display the graphic is moved s...

PURPOSE:To dispense with an ultraviolet transmitting window material and to easily carry out an erase of the memory contents by a method wherein an ultraviolet generating layer is provided on a semiconductor chip and a synthetic resin package is formed so as to cover the chip and the generating layer. CONSTITUTION:An energy beam excitation ultraviolet generating layer 5, which generates ultraviole...
