Abstract: PURPOSE:To perform final stage charging control by connecting the output terminal of a rectifying circuit to a battery and providing the output from a differential voltage detecting means to means for extracting a micro voltage fluctuation thereby controlling charging operation of the battery upon extraction of a micro voltage fluctuation. CONSTITUTION:Output V1 from a switching circuit 13, connected with a rectifying circuit 12, is provided to an input terminal (a) of a differential amplifying circuit 17. Consequently, a voltage predetermined times as large as a micro voltage fluctuation appears on the output Vc of the differential amplifying circuit 17 and it is fed to the input terminal (d) of a bandpass filter 18. An output corresponding to the micro voltage fluctuation of the terminal voltage V3 of a battery 15 appears on the output terminal (e) of the bandpass filter 18. A pulse signal corresponding to the micro voltage fluctuation of the battery 15 appears on the output of a voltage comparator 21 and the pulse signal is fed to the input terminal (h) of a counter circuit 22. The counter circuit 22 counts the pulse signal and resets a flipflop 23 when the count reaches (n).

Title: Dc type plasma display panel
Inventor: FUJII HIDEAKI
IPC: H01J17/49
Filed: 1992-05-11
Abstract: PURPOSE:To enhance luminous efficiency a DC type plasma display panel.

Title: Speaker diaphragm
Inventor: YAMAMOTO TOSHIAKI
IPC: H04R7/08
Filed: 1979-11-06
Abstract: PURPOSE:To prevent divisional vibration, by making thick the center of the diaphragm substance, where the band-form material where a wave-form sheet is caused to adhere to a plane sheet is wound, or using a wave-form sheet of fine waves to constitute the speaker diaphragm. CONSTITUTION:Band-form material 4 is wound spirally around the circumference into a disc form in the upper part of bobbine 3 having voice coil 2. In band-form material 4, triangular wave-form sheet 5 is caused to adhere onto the surface of plane sheet 6, and edge lines are made orthogonal to the longitudinal direction of sheet 6.

Title: Lead frame for semiconductor device
Inventor: OKUAKI YUTAKA
IPC: H01L23/50
Filed: 1985-07-02
Abstract: PURPOSE:To improve the drawing strength and moisture resistance of leads by forming a plurality of cutouts at the peripheral edges of an island, opposing the ends of the leads to the cutouts, and forming connecting portions at the ends of the leads. CONSTITUTION:When supporting members 22, islands 23 and leads 24 are formed by thin iron plates, the upper and lower sides of the islands 23 are separated from the ends 24a of the leads at an insulating distance, cutouts 23a are formed at the right and left sides of the islands 23, and the cutouts 23a are separated from the ends 24a of the leads at an interval. Then, when the ends 24a of the leads are bent to form connecting portions 24b, the ends 24a of the leads move outward rightward and leftward directions to form insulating distances L1 to the cutouts 23a. Thus, since the cutouts 23 are formed at the peripheral edges and the ends 24a of the leads are opposed near the cutouts 23a when the island 23 is increased, the length of the ends 24a of the leads can be increased to readily form the connecting portions 24b, thereby improving the drawing strength and the moisture resistance of the leads 24.

Abstract: PURPOSE:To maintain the reliability extending over a long period of time, to reduce the power consumption, and to detect an accident in a long distance by receiving and analyzing the corresponding intensity modulation optical signal by an optical confluence device provided on an optical fiber being parallel to a transmission line. CONSTITUTION:When such an accident as an abnormal current flows to a transmission line is generated, by an abnormal current detector, from one of electro-optical transducers 16A, 16B existing in the corresponding position, an optical signal of a natural frequency corresponding to its position is led into an optical fiber through one of optical multiplexer 14A, 14B. This optical signal is converted to an electric signal by an opto-electric transducer 18, its frequency is analyzed 20 and an accident position is detected. In this case, a confluence ratio of the optical signal is set in advance so that all optical signal outputs be come equal by a detecting terminal, therefore, all positions can be detected with the same sensitivity, and a detection distance can be taken long. Also, since the optical signal is brought to multiplex, the reliability can be maintained extending over a long period, and since the transducers 16A, 16B are driven only when an accident is generated, the power consumption is reduced, and the device can be used economically.

Abstract: PURPOSE: To provide the picture input device which enables an operator to easily recognize the document setting position even in the case that the optical axis position is deviated from a normal image pickup position by switching to the close-up position, replacement of a camera part, or the like. CONSTITUTION: A picture input device 1 is so constituted that a first camera part 2 can be replaced. Leg parts 7 and 8 are provided with light emitting elements 34 and 37 which emit the red light and light emitting elements 35 and 36 which emit the green light so that optical axis positions 15 and 16 of the first camera part 2 can be recognized more distinctly. Since green light emitting elements 35 and 36 are lit by power-on in the case of the first camera part 2, the optical axis position 15 of the first camera part 2 is recognized. For example, when the center part of a document 6 is aligned to this position, the document 6 is projected on the whole of the screen of a monitor 18. At the time of zooming up a required part, this part is brought to the optical axis position 15.  When a second camera part is used, red light emitting elements 34 and 37 are lit, and the optical axis position 16 of the second camera part is recognized.
