Abstract: PURPOSE:To obtain molybdenum trioxide (MoO3) active substance capable of giving lithium cells great in both charge and discharge capacities with improved charge characteristics by converting a Mo-based raw material into a peroxide followed by deoxygenation treatment to make said peroxide porous. CONSTITUTION:Firstly, a Mo-based raw material (e.g., (NH4)2MoO4) is made to react with a peroxide (pref. H2O2) to from a peroxide MoO3(OH)2.H2O. This peroxide is heated to <=200 deg.C (e.g., 170 deg.C) to cause deoxygenation and partial dehydration to produce a porous MoO3 active substance. This substance is then applied on a net substrate made of Ni to make the objective anode plate for Li cell. In case said peroxide is heated to >=200 deg.C (e.g., 400 deg.C), further dehydration is caused, producing a porous MoO3 active substance with little OH group left. The charge characteristics of a cell using this substance is such that in the ending time of the charge, voltage becomes constant, therefore, this cell is useful as a secondary battery.

Abstract: PURPOSE:To exactly execute a search stop by providing a first logic circuit to AND between the zero point detection signal of a signoidal characteristic voltage, which is obtained from an FM frequency detection signal, and the level detection signal of an intermediate frequency circuit and executing the search stop according to a signal from this first logic circuit. CONSTITUTION:Since a signoidal characteristic voltage Vs is outputted from an FM frequency detection circuit 5 and inputted to comparators 7 and 8, an output voltage Va is made 'L' in the non-inversion comparator 7 when the voltage Vs lower than a reference voltage V1 is inputted. Then, in the inversion comparator 8, when the voltage Vs higher than a reference voltage V2 in inputted, an output voltage Vb is made 'L'. In an intermediate frequency circuit 4, when an intermediate frequency signal effectively exists, the level of a voltage Vc in a terminal 4a is lowered to 'L'. Thus, a pulse Vd showing a central frequency can be extremely exactly taken out by suitably setting the reference voltages V1 and V2 of the comparators 7 and 8 and the search stop can be exactly executed.

IPC: B63B35/00
Filed: 1989-03-28
Abstract: PURPOSE:To enable dredging of quantities of soils by a method wherein the ship hull of a bottom openable barge forms a buoyant body and a bottom opening and closing part forms shells for excavating soil, the whole is sunk down on a sea bottom, sea bottom soil is excavated by means of an excavating shell, and dredged soil is placed between the shells for floating. CONSTITUTION:In a dredging work, water in hollow parts 1a-3a of a buoyant body is drained, and the buoyant body is tagged in a state in which a ship hull floats on a water surface 12. At a dredging site, two shells 3 and 3 are unfolded as water is injected in the hollow parts 1a-3a to reduce buoyancy, and the ship hull is gradually sunk. After the ship hull is seated on soft soil 13 on a seat bottom in a state that the shells 3 and 3 are unfolded, by closing the shells 3 and 3, sea bottom soil is excavated, and excavated soil is contained in a containing part 5. By increasing buoyancy in a way that water in the hollow parts 1a-3a is drained, the ship hull is floated from the water surface 12 in a state to load soil in the ship hull. After the ship hull is tagged to a dumping place, e.g. a reclaiming ground, the shells 3 and 3 are unfolded to dump soil.

Title: Precision positioning device
Inventor: MUNEKATA MUTSUO
IPC: G12B5/00
Filed: 1995-03-30
Abstract: PURPOSE: To reduce the noise generated by the operation by forming the right and left and the upper and lower mass asynmetrically in the section which is crossed at right angles with the axial direction of the inertia. CONSTITUTION: A precision positioning device 1 is provided with a box 2. An inertia body 4 is provided on a piezo-electric actuator element 3 by a fixing member 5. Further, a sliding member 7 which supports a moving body 6 is provided. In this case, when vibration due to the operation of the piezo-electric actuator element 3 occurs, the inertia body 4 is resonant with the vibration and produces vibrating sounds. In the inertia 4, the mass or the shape or its component material is formed asynmetry in all directions in the section crossed at right angles with the axial direction. Thus, the natural frequency is not matched completely as against being formed synmetrically and the noise is reduced because the frequency is changed to the soundwave with plural resonance frequencies having the amplitude lower than that when the frequencies are matched.

IPC: H01M4/62
Filed: 1982-04-30
Abstract: PURPOSE:To enhance the performance of an organic electrolyte battery by improving the conductivity and the liquid-holding ability of a positive electrode by combining a positive active material made of a metal oxide or the like with a carbon black which is used as a conductive agent and has a hollow shell-like granular structure. CONSTITUTION:After manganese dioxide is mixed with a conductive agent consisting of a carbon black such as Koetchen black which has a hollow shell-like granular structure consisting of a thin film of concentrated graphite crystals, fine-hole peaks at the radiuses 8Angstrom  and 20Angstrom  and a porosity of 69.3%, a conductive agent is added to the mixture, and thus prepared mixture is pressed and molded so as to make a positive electrode 3. Then an organic electrolyte battery is constituted by combining the positive electrode 3 with a separator 5 and a negative electrode 4. As a result, since the distances between the particles are short due to the hollow shell like structure, the conductivity of the positive electrode 3 can be enhanced due to tunnel effect. Besides, due to the high porosity of the particles, the liquid-holding ability of the positive electrode 3 can be increased. Consequently, the high-rate electric-discharge characteristic and the low-temperature electric-discharge characteristic of the battery can be improved.

Abstract: PURPOSE:To reduce number of band limit means in use. CONSTITUTION:A beam index system color cathode ray tube is used for the display device, which has a run-in section arranged in the horizontal scanning direction of an electron beam and a video image section for displaying a video image, applies point sequential control to a primary color signal based on an index signal obtained by the run-in section to display a color video image. A composite video signal SV is fed to a Y/C separation circuit 32, in which the signal is separated into a luminance signal Y and a chrominance signal C. The luminance signal Y after the separation is band-limited by a low pass filter 80 so as to be immune to the index signal SI and plural primary color signals are converted based on the band-limited luminance signal Y' and the chrominance signal C and the plural converted primary chrominance signals R', G', B' are subject to point sequential processing and the resulting signals are fed to the color cathode ray tube. Even when the three primary color signals are used, since one band limit means is enough for the purpose, the cost is reduced.

Abstract: PROBLEM TO BE SOLVED: To provide a monostable mutlivibrtor circuit which can obtain the output of fixed pulse width despite a small input pulse interval by preparing a discharge circuit which consists of a bias circuit having its output impedance lower than that of a differential circuit consisting of a capacitor and a resistance and can quickly discharge a capacitor. SOLUTION: When the voltage of input 1 is set at an L level, voltage 2 is set at a VH level and voltage 3 is also set at a VH level. Then the input of an inverter U2 exceeds its inherent threshold level. The voltage 3 drops less than it threshold by a time constant C1.R1 according to the charging of a capacitor C1, and output voltage 4 is kept at an L level while the voltage 3 is kept higher than its threshold. When the output is reset at an H level with the input set at an H level respectively, the capacitor C1 discharges and is reset in its initial state. Then the current is supplied from a fast discharge circuit connected to the capacitor C1, and the capacitor C1 is quickly and completely discharged. Accordingly, the discharge waveform of the capacitor C1 becomes a thin pulse of negative polarity.
