Title: Manufacture of semiconductor device
Inventor: YORIKANE MASAHARU
IPC: H01L29/73
Filed: 1989-11-21
Abstract: PURPOSE:To reduce element area, and realize high speed operation and high density integration, by simultaneously determining the relative positions of trenches having different depths in the same photoresist process, and forming these trenches in the same etching process. CONSTITUTION:Photoresist 114 is arranged as the mask material of trench etching, heat treatment is performed at about 150 deg.C; photoresist process using thin photoresist material is again performed, thereby forming photoresist 114A in the region where shallow trenches are to be formed in the later process. When etching is performed by using reactive ion etching method, the photoresist also is etched. As a result, shallow trenches are formed in the regions where the photoresist 114A is left, and deep trenches are formed in the regions where the photoresist 114A is not present. ln this manner, the relative positions of trenches having different depths can be precisely defined by the same photoresist process, so that the semiconductor element area is microminiaturized. Thereby high density integration of a semiconductor device and high speed operation in virtue of parasitic capacitance reduction can be realized.

Title: Table construction of image drawing device
Inventor: ANDO HIROAKI
IPC: B43L13/00
Filed: 1988-12-01
Abstract: PURPOSE:To enable yawing of a table to be controlled and to enable the table to be applied to a continuously transferring device also by a method wherein a work table connected by a connection means having rigidity in one direction to a master table and besides, having elasticity in a direction at a right angle to the direction, is provided. CONSTITUTION:Driving force to be applied to a master table 110 is transmitted to a work table 150, and the work table 150 in slid. Thrust direction force received with the master table 110 is transmitted as it is to the work table 150. However, since elasticity is provided in a direction at a right angle to the sliding direction, even in the case where yawing of the master table 110 is caused by radial direction component force, a plate spring absorbs this yawing, and only the thrust direction force is transmitted to the work table 150. Therefore, the yawing of the work table 150 can be effectively restrained even though an electrical correction means or the like are not used, and an influence based on a transfer error of the table in the case where precise image drawing is performed can be removed by a simple construction.

IPC: A61K31/352
Filed: 1994-12-08
Abstract: PURPOSE: To obtain a medicine composed of a benzopyran derivative, and capable of selectively inhibiting cyclooxygenase-2 (COX-2) and suppressing the induction of COX-2 expression. CONSTITUTION: This medicine is obtained by compounding 3-formylamino-7- methylsulfonylamino-6-phenoxy-4H-1-benzopyran-4-one. Cyclooxygenase (COX) is a rate-determining enzyme for prostaglandin production and consisting of physiologically different two isozymes of COX-1 and COX-2. The COX-1 is a constituting enzyme existing in most tissues and the COX-2 is an inducible enzyme expressed in cells at an inflammatory site in an induced manner by various kinds of stimulation. The benzopyran derivative suppresses PGE2 production selectively at the inflammatory site scarcely affecting COX-1 which has an important role in homeostasis of a body. The benzopyran derivative is useful as a medicine having high tolerance e.g. at digestive canal or kidney. The medicine is orally or parenterally administered at a daily dose of 0.05-1000mg/kg for an adult in one or several divided doses.

Title: Television receiver
Inventor: HOSODA KIYOSHI
IPC: H04N5/63
Filed: 1992-11-16
Abstract: PURPOSE:To reduce power consumption and to prevent a fault by applying power to the signal processing system of a specific broadcasting signal only when the specific broadcasting signal is judged to be selected. CONSTITUTION:A control microcomputer 4 judges whether or not the BS broadcasting being received is the one based on the MUSE system. When the result of discrimination is the BS broadcasting which is not based on the MUSE system, a MUSE decoder power source control signal (power source control signal) stopping the power supply to a MUSE decoder 9 is formed in the control microcomputer 4. The power source control signal is supplied to a MUSE decoder power source circuit 20 and the power to the MUSE decoder 9 is cut. On the other hand, when the discrimination result is the BS broadcasting based on the MUSE system, no power source control signal is formed. Thus, the power supply to the MUSE decoder 9 is continued. In short, the power is supplied to the MUSE decoder 9 only when receiving the MUSE broadcasting.
