Title: Active hybrid circuit
Inventor: KIMURA NOBUYOSHI
IPC: H03H11/02
Filed: 1984-10-05
Abstract: PURPOSE:To attain a hybrid circuit which is capable of mixture and separation even to the transmission reception signals containing DC components, by using an active hybrid circuit containing a differential amplifier. CONSTITUTION:A reception signal UR is connected to an output terminal 2 of a differential amplifier 10. While a feedback resistance 12 is connected between a reverse input terminal and an output terminal. Then a resistance 11 and an input/output double terminal network 13 are connected between the reverse/non-reverse terminal of the amplifier 10 and a terminal 1 which supplies a transmission signal VS. Furthermore a transmission line 9 is connected between the non-reverse input terminal of the amplifier 10 and an earth. Thus the transmission signal supplied to the terminal 1 is delivered only to the line 9 according to the in-phase signal eliminating ratio of the amplifier 10. While the reception signal is amplified with no inversion by the amplifier 10 and delivered to the terminal 2.

Title: Liquid crystal display element and its production
Inventor: KAWABATA KUNIHARU
IPC: G02F1/1333
Filed: 1995-08-16
Abstract: PROBLEM TO BE SOLVED: To prevent the deviation and movement of substrates at the time of baking and to improve a yield by forming a sealing material so as to include a first thermosetting resin which cures at a prescribed temp. and a second thermosetting resin which cures at a lower temp. SOLUTION: The material of the sealing material 2 to be applied on either substrate 1 of a pair of the substrates 1 is formed of a mixture composed of the first thermosetting resin which cures at the prescribed temp. T and the second thermosetting resin which cures at the temp. T1 (T1<T) lower than the curing temp. of this first thermosetting resin. The second thermosetting resin is once softened to a paste form and is then cured by changing to a solid shape when the temp. of the sealing material 2 attains T1 at the time of baking. The first thermosetting resin does not attain this curing temp. T at this time and, therefore, maintains the solid state and consequently, the deformation of the sealing material 2 is suppressed by the first thermosetting resin in the solid state even if the second thermosetting resin temporarily is softened to the pasty form.  The deviation and movement of both substrates 1 superposed on each other are thus prevented.

Title: Tape end detector
Inventor: FUJITA NAOYA
IPC: G11B15/093
Filed: 1981-12-28
Abstract: PURPOSE:To detect the end of a magnetic tape securely in a short time by  detecting and comparing the revolving speeds of a take-up and a feed reel. CONSTITUTION:The revolving speeds of the take-up and feed reels 10 and 11 are detected by the 1st and the 2nd detecting circuits 12 and 13 and then transduced into DC voltages by the 1st and the 2nd F/V circuits 14 and 15, respectively. In the former half of the magnetic tape, the revolving speed of the take-up reel 10 is greater and in the latter half, the revolving speed is less, so a comparing circuit 16 outputs signals differing in polarity in the former and latter halves, respectively, e.g. a signal with a level ''1'' in the latter half. Thus, the comparing circuit discriminates between the former half and latter half of the magnetic tape. For this purpose, the output terminal of the comparing circuit 16 and that of a counting circuit 9 are connected to an AND circuit 17. Consequently, only when a leader tape part at the end of the magnetic tape is detected, the AND circuit 17 outputs a tape end detection signal to detect the end of the magnetic tape.

Abstract: PURPOSE:To reduce a load given to a hinge part when a shutter is folded and further, to easily position two shutters via the hinge part by folding the shutter double on the hinge part so as to be like a plate, and forming the hinge part so that its outside is thin and wide. CONSTITUTION:The shutter 01 is folded on the hinge part 04 so as to be like the plate. The shutter 01 is formed by connecting two vertically/integrally formed shutters 01a and 01b, via the hinge part 04 widely formed by a horn-like groove, inside, and folded by executing alignment so as to engage alignment parts 06b and 06a provided next to the hinge part 04. When the shutter 01 is folded like this, the hinge part 04 is bent so as to obtain comparatively large curvature, and the load given to the hinge part 4 is reduced. On the other hand, since the alignment parts 06a and 06b exist, two shutters 01a and 01b are not deviated. These shutters are used in such a manner that a shielding film passes between these two shutters.
