Filed: 1988-10-31
Abstract: PURPOSE:To prevent a magnetic tape and a magnetic head from wearing by eliminating excessive residual tape tension when a fast forwarding mode of the tape under the state of winding around a head cylinder is shifted to a stopping mode. CONSTITUTION:When the fast forwarding mode of FF and REW is shifted to the stopping mode, reel bases 1 and 2 are once stopped first, and then an operation similar to a recording or reproducing mode is performed. That is, the tape is fed by a capstan 4, and the tape is traveled at low speed by the reel base 2 on the take-up side, and also the head cylinder 3 is rotated. Moreover, a tension servo mechanism 10 is operated to adjust the tape tension, and after this operation in a short time the reel bases 1 and 2, etc., are stopped to make the stopping mode. Thus, by operating the tension servo mechanism 10 for a short time after completing the FF or REW mode, excessive tape tension does not remain.

Title: Compound semiconductor integrated circuit
Inventor: SHIGETA JUNJI
IPC: H01L27/095
Filed: 1986-11-21
Abstract: PURPOSE:To improve the performance of a compound semiconductor integrated circuit by forming FETs requiring large gate breakdown strength in a large number of FETs used for the integrated circuit in LDD structure and shaping FETs needing small parasitic resistance in conventional structure. CONSTITUTION:A DCFL (Direct Coupled FET Logic) circuit consisting of a D type (Depletion type) FET and an E type (Enhancement type) FET is often employed in a compound semiconductor, particularly, a GaAs integrated circuit. Since the DFET requires gate breakdown strength of approximately 7V or more and the resistivity of a conductive layer is reduced to approximately 1KOMEGA/square, LDD structure is proper to DFET because parasitic resistance is not so much increased remarkably even when a high-concentration impurity layer and a gate electrode are isolated. Since the gate breakdown strength of the EFET may be minimized to approximately 5V and the resistivity of the conductive layer is augmented to approximately 4KOMEGA/square or more, on the other hand, conventional structure is more proper to the EFET because parasitic resistance is increased by isolating the high-concentration impurity layer and the gate electrode. Accordingly, the DCFL circuit having high performance can be constituted by properly using both structure.

Abstract: PURPOSE:To output the retrieved contents with contents to be comprehended easily for users while saving labor and time by translating a structured query language (SQL) into Japanese and adding the source SQL to the result. CONSTITUTION:The SQL sentence is executed by a central processing unit (CPU) 21 and the retrieved result matched with the retrieval conditions of the SQL sentence is provided from a relational data base (RDB) inside a storage device 24.

Further it is tested whether the keywords are still remained in the SQL under processing or not, and it is repeated until all the keywords in that SQL sentence are completely detected. Since this SQL arranges the limited keywords in the decided order differentially from any natural language, the SQL can be easily replaced with Japanese. Then, the translated Japanese is outputted to an output device 23 as a title together with the retrieval result.
