Title: Signal output variable amplifier
Inventor: NOMITSU EIKOU
IPC: H03G3/12
Filed: 1980-07-12
Abstract: PURPOSE:To adjust the amplification factor of an amplifier and the input signal inputted to the amplifier at the same time, by interlocking an input signal adjusting variable resistor and a negative feedback adjusting variable resistor 2. CONSTITUTION:When an input signal is small, an input signal adjusting variable resistor 1 is increased (r2 greater, r1 smaller) to increase the rate of the input signal inputed to an amplifier A, and an amount of the negative feedback is reduced with a negative feedback adjusting variable resistor 2 (R2 greater, R1 smaller) to increase the amplification factor of the amplifier. On the other hand, when an input signal is greater, the rate of an input signal is decreased to reduce the amplification factor. Thus, one knob and one amplifier can handle any signal from a very small to very large input signal.

Title: Battery charging system
Inventor: OCHIAI YUKINOBU
IPC: H02J7/00
Filed: 1997-04-14
Abstract: PROBLEM TO BE SOLVED: To accurately control the charging of a battery which is used as the power source of an electric automobile when a power failure occurs while the battery is charged and when the power supply is restored. SOLUTION: A charge control computer 30 which uses an auxiliary battery 24 as a power source stores the already spent charging time of a battery 12 until a power failure occurs in a RAM 38 when the computer 30 detects the interruption of external AC power supply 36 from the level fluctuation of a power failure on/off signal Si while the battery 12 is charged. Then the computer 30 immediately changes its own operation mode to a low-power operation mode from a normal-power operation mode. When the computer 30 detects the restoration of the power supply 36 thereafter, the computer 30 restarts the charging of the battery 12 by setting new target charging time from the previous target charging time and the stored already spent charging time. Therefore, the use of the auxiliary battery 24 during the power failure can be minimized.  In addition, the battery 12 can be charged accurately and fully after the power supply is restored.

Title: Liquid-crystal display device
Inventor: HARAJIRI TOSHIHIKO
IPC: H01L27/12
Filed: 1986-04-25
Abstract: PURPOSE:To reduce the fraction defective of a liquid-crystal display device without worsening the display quality, by forming a transparent conductive film made of the same material as that used for a picture element electrode at the place where the picture element electrode is put on a metallic electrode so that the former cannot be contacted with the latter. CONSTITUTION:After transparent conductive films 12 and 13 are deposited on a base plate 11, a pattern is formed by photoetching. Then another pattern is formed after an amorphous material 14 which is composed mainly of silicon is deposited and one 15 of matrix electrodes is deposited. After the deposition, the electrode 15 is selectively formed by photoetching so that, at least, a part of the electrode 15 can be contacted with the auxiliary electrode 13 and a liquid crystal layer 16 is put between an upper transparent base plate 18 with a selectively formed transparent conductive film 17 and the base plate 11. Therefore, the electric current flows smoothly due to the auxiliary electrode 13 even when the metallic electrode 15 which is a line or row electrode is partially disconnected. Moreover, the necessity of widening the line width of the electrode 15 is eliminated even if large-picture display is made, since the metallic electrode 15 and auxiliary electrode 13 are connected in parallel and the electric resistance can be reduced. Thus a liquid-crystal display device which is high in numerical aperture and excellent in picture quality can be realized.

Title: Target for rotary anode x-ray tube
Inventor: KOTABE MUNETOMO
IPC: H01J35/10
Filed: 1981-06-24
Abstract: PURPOSE:To enhance the work efficiency of an X-ray tube, which is prepared from a rotary anode having a graphite base, by providing a metallic covering layer used for the X-ray radiation on both surfaces of a circular graphite base body. CONSTITUTION:Both surfaces of a circular graphite base body 11 are provided with a metallic covering layer 12 which is used for the X-ray radiation, made of tungsten or a rhenium-tungsten alloy, and the sectional form of which is a truncated conic section having a diagonal line slanting from the rotational axis at over 90 deg. and a diagonal line slanting from the rotational axis at under 90 deg.. An upper slant surface 16 and a lower slant surface 17 of the layer 12 are apart from the direction perpendicular to the rotational axis in reverse directions by an equal angle. The upper inner diameter (phiA) of the layer 12 and the lower inner diameter (phiB) of the layer 12, which are both perpendicular to the rotational axis, are made different. Since the heat radiating ability of the graphite exposed part is higher than that of the rhenium-tungsten covering layer 12, the lower part of the target can radiate much more heat than the upper part of the target in this case (when phiA<phiB).
