IPC: H01L31/042
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To miniaturize and lighten a solar battery by eliminating the combined use of a capacitor and a rectifier in the case of application to various equipments, by incorporating capacitive function in the solar battery. SOLUTION: A solar battery is composed wherein an n type semiconductor layer and a p type semiconductor layer are fundamantarily laminated, and furthermore, a transparent electrode layer is laminated on the n type semiconductor side while a metallic electrode layer is laminated on the p type semiconductor side for composing a compound laminated body. Then, the light emitted from the transparent electrode side is converted into a current by the n type and p type semiconductor layers to activate the metallic electrode layer and the transparent electrode layer as a positive polarity and a negative polarity, respectively.  In such a constitution, a compound oxide layer in amorphous structure represented by a composition formula: (Ti1-x Fex ) (where x:0.02-0.35, y: 1.5-2.0 in atomic ratio) is laminated in 1-5 μm of mean layer thickness between the transparent electrode layer and the n type semiconductor layer.

IPC: H04N5/91
Filed: 1984-02-17
Abstract: PURPOSE:To enable retrieval by an efficient picture by calculating continuously a differential picture at every one field and a statistical amount of an original picture with respect to a picture sequence continuously recorded, and extracting a relative change. CONSTITUTION:A continuous picture sequence 1 is sequentially stored in plural units of picture memory 21-24. A logical processing circuit 5 carries out judgement under the following conditions; where mp>M2, and M2>m2 and mb>M1, a scene change, etc., are assumed to be generated at a time tp, and a selection circuit 6 selectively outputs the picture memory 22 or the picture memory 23. An output picture of the selection circuit 6 is reduced to the specific size by a reduction circuit 7, impressed to an index picture recording control circuit 8, and recorded as an index picture on a recording medium such as a VTR where a continuous picturs are recorded. At the same time, the control circuit 8 has a function for deciding uniquely the relation between an index picture and a continuous one as an original picture. Thus the retrieval by using an index picture as a content one can be possible in order to search an arbitrary picture from a large amount of continuous pictures recorded on a VTR, etc.

Title: Optical voltage adder
Inventor: MITSUI TSUTOMU
IPC: G02F1/03
Filed: 1985-02-14
Abstract: PURPOSE:To detect easily a residual voltage on a polyphase AC distribution line with a simple constitution by adding optically plural voltages by one optical voltage adder to obtain intensity modulation of light dependent upon the sum of individual voltages. CONSTITUTION:The light incident on a polarizer 1 is polarized linearly and is subjected to phase modulation proportional to the sum of modulating voltage VA, VB, and VC from three-phase AC distribution lines lA, lB, and lC by the Pockels effect when passing Pockels elements 2A, 2B, and 2C and becomes an elliptically polarized light. This elliptically polarized light passes a 1/4 wave plate 3 and an analyzer 4 to become a linearly polarized light again. Since the elliptically polarized light is changed in accordance with the sum of modulating voltage VA, VB, and VC, it is converted to the change of the intensity of light through the analyzer 4. The output light from the analyzer 4 passes an optical fiber 7 and is converted to an electric signal proportional to the intensity of the output light by a photo diode 10 of a transducer 8 and is outputted as the sum of modulating voltage VA, VB, and VC, it is converted to the change of the intensity of light through the analyzer 4. The output light from the analyzer 4 passes an optical fiber 7 and is converged to an electric signal proportional to the intensity of the output light by a photo diode 10 of a transducer 8 and is outputted as the sum of modulating voltage VA, VB, and VC, namely, the residual voltage. Thus, the residual voltage is detected easily by the simple constitution.

Title: Controlling method of reactive power
Inventor: KAWAGUCHI JIYUNICHI
IPC: G05F1/70
Filed: 1982-02-24
Abstract: PURPOSE:To enable control of reactive power for a highly accurate system with the minimum necessary equipment, by controlling the large-capacity capacitor group and the small-capacity capacitor group with different reactive power controllers, respectively. CONSTITUTION:A reactive power controller 7 works when the delayed reactive power increases after the application is through for all switches 8, 9 and 10 of a capacity having small unit capacity. Then a capacitor 17 of large unit capacity is connected to a bus 4 with application of a capacity switch 11. In this case, if the capacity of the capacitor 17 is larger than the increment of the delayed reactive power of a system, the system has the advanced reactive power. Thus a reactive power controller 6 works. As a result, one of capacitors 14, 15 and 16 of small unit capacity which is equivalent to the advanced reactive power is cut off from the bus 4 when one of the switches 8, 9 and 10 is cut off.

Title: Tension testing device for brittle material
Inventor: INUKAI TAKAO
IPC: G01N3/08
Filed: 1986-02-14
Abstract: PURPOSE:To obtain a high-accuracy tension testing device for brittle materials by moving a loading shaft so that the bending load on a bending detection load cell is zero. CONSTITUTION:When a tensile load is increased by springs 13 and 13, the bending load is placed on the bending detection load cell 7. At this time, a signal proportional to bending moment is outputted from the load cell 7 and inputted to a servo controller 9 through an amplifier 8, so that the signal is inputted as a control signal to servo motors 12a and 12b which drive a movable base 11 on a cross head 10. The controller 9 controls the servo motors 12a and 12b individually so that the signal of the load cell is zero. Thus, the bending moment of the load cell 7 is eliminated by a servo mechanism to eliminate substantially the bending moment generated in a test-piece 1. Thus, the high- accuracy tension testing device for brittle materials such as ceramic is obtained.

Title: Differential amplifier
Inventor: KOMODA TAKUYA
IPC: H03F3/45
Filed: 1981-02-28
Abstract: PURPOSE: To increase a dynamic range without decreasing the gain of a differential amplifier, by making the saturation currents of both transistors (TR) of the amplifier different.  
     CONSTITUTION: The emitters of TRs Q1 and Q2 are connected in common and grounded through a constant current power source IO. The collectors of the TRs Q1 and Q2 are both connected to a power source Vcc through a load resistance Rc, and power sources E1 and E2 are connected to their bases. When the saturation current of the TRQ2 is set (n) times that of the TRQ1, the voltage gain of a differential amplifier has little variation, i.e. is nearly equal to that when n=1 unless (n) is extremely large, thereby increasing the dynamic range of a collector current Ic2 nearly (n) times. To the TRQ1, the TRQ1 having emitter area equal to that of the TRQ1 is connected in parallel, and an FET may be used as said TR.
