Patent JP-H039879-A (JP)
Title: Thermal recording paper
Inventor: NOGUCHI KENJI
IPC: B41M5/41
Filed: 1989-06-06
Abstract: PURPOSE:To eliminate the curl at the times of high and low humidities and to obtain recording of high sensitivity by using base paper prepared from dry pulp under such a condition that the heating degree of the pulp is set to a specific range by a papermaking process as a support. CONSTITUTION:When heating degree as Canadian Standard Freeness advances to 250cc (CSF) or less, the entanglement of fibers is enhanced and contact points increase even when dry pulp is used and, therefore, the extensibility of paper increases and heat insulating effect becomes poor because of the reduction of voids in a paper layer. Therefore, the heating degree is set to 250cc (CSF). Contrarily, since voids increase excessively in an unbeaten state, a coating solution passes through the paper layer when a thermal layer is applied to be bonded to and accumulated on a backing roll and paper becomes easy to cut. Therefore, dry pulp is beaten to 550cc (CSF) or less. When thermal paper is prepared by applying a thermal coating solution to the base paper using this dry pulp directly or through an intermediate layer, the curl of thermal paper is almost eliminated because the extensibility of the base paper is low even when humidity changes.

Title: Manufacture of semiconductor device
Inventor: MAEDA TETSUYA
IPC: H01L27/092
Filed: 1990-05-31
Abstract: PURPOSE:To compose a photolithography step only before one type of ion implanting and to simplify steps by conducting one type of ion implanting, then executing an oxidizing step, and then conducting second type of ion implanting. CONSTITUTION:When a desired region of a substrate is covered with photoresist, one type of ions, P ions are implanted by implanting, the photoresist is then removed, and oxidized, the ion implanted part is oxidized several times as compared with the oxide film of the part not oxidized by ion implanting. Accordingly, the P ion implanted part becomes an N-type semiconductor in which P ions are controlling. Since the thickness of the oxide film is about 200Angstrom  in the part in which the P ions are not implanted, they sufficiently penetrate the oxide film by scores (keV) of implanting energy. Therefore, the substrate silicon becomes P-type semiconductor by BF2 ions.
