Title: Static protective relaying device
Inventor: ANDOU FUMIO
IPC: H02H3/02
Filed: 1978-05-16
Abstract: PURPOSE: To prevent the false operation of a relaying device due to the opening of a contact circuit of a switch for a setting circuit for selecting the reference quantity of electricity in the case when altering setting, by connecting a movable contact of the switch and an arbitrary point of a potential dividing circuit.  
     CONSTITUTION: When the quantity of electricity input is compared with the reference quantity of electricity by means of an operational amplifier 0A and trip output is obtained, an arbitrary electric potential point c, which is not less than zero, of a potential dividing circuit for setting the reference quantity of electricity and a movable contact of a switch SW are connected by means of an external circuit l. Thus, since reference currents equal to currents in the case when the movable contact d and the fixed contact c are connected pass through the external circuit l and automatically flow under a condition that the movable contact d of the switch SW is not connected to all fixed contacts a, b, c when altering setting, the action condition of a relay during a period of the opening of the switch SW is used as the maximum setting value, and false operation during the period can perfectly be prevented.

Title: Burst gate pulse generating circuit
Inventor: KOYANO ATSUSHI
IPC: H03K3/033
Filed: 1986-03-14
Abstract: PURPOSE:To simplify a circuit constitution and to stabilize a pulse duration by adjusting a pulse duration by a time constant circuit connected to the one side transistor of a comparator. CONSTITUTION:When the level of an input pulse d is L level, the potential of a nodal point N6 is higher by V1 than the potential of a nodal point N7 and the level of a burst gate pulse (e) outputted from the collector of a transistor 13 goes to the L level. Then, when the level of an input pulse (d) goes to H level, the entire potential of the respective nodal points N4-N7 is lowered by a potential difference V2. Accordingly, the level of the burst gate pulse (e) is still the L level. When the level of the input pulse (d) goes to the L level again, the potential of the nodal point N6 rises at the time constant of tau=C3R3 by a time constant circuit consisting of a capacitor 15 and a resistance 16 and a period in which the potential of the nodal point N6 is lower than the potential of the nodal point N7 is produced, in this period, the level of the burst gate pulse (e) goes to H and the burst gate pulse (e) is generated and the burst signal of a waveform B is extrated.

Filed: 1983-03-31
Abstract: PURPOSE:To obtain a high-precision and high-resolution detector by extracting an electric signal corresponding to an engine speed from an ignition coil and increasing it to an integral multiple by a phase locked loop circuit combined with a frequency dividing circuit. CONSTITUTION:The primary-side signal of the ignition coil 1 is passed through a waveform shaping circuit 3 to remove its noise component firstly, and then the resulting signal is sent to a phase comparator 4. Two rectangular-wave pulse signals, i.e. the output of the waveform shaping circuit 3 and the output of a 1/10 frequency dividing circuit are inputted to output a current corresponding to the phase shift between both signals to an integration circuit 5. A voltage- controlled oscillation circuit 6 generates a pulse according to the output current and its frequency is divided by ten through a frequency dividing circuit 7 and fed back to the phase comparator 4. This feedback loop synthesizes a frequency which is 10 times as high as the output pulse frequency of the waveform shaping circuit 3 and the frequency is led out to the output terminal of the voltage- oscillation circuit.

Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To execute sputtering for preventing the light absorption of a thin film caused by the intrusion of atoms from a tray to be supplied with a film raw material. SOLUTION: A film raw material composed of granular MgF2 having 0.1 to 10.0mm grain size is put in a tray consisting essentially of SiO2 or Al2 O3 , ac voltage is applied to a sputtering electrode mounted with this tray to generate plasma, and the film raw material is sputtered to form an optical thin film on a substrate arranged oppositely to the film raw material.

Title: Motor and output apparatus providing the same motor
Inventor: KUSUMI SABURO
IPC: H02K41/03
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To obtain a motor which can generate a higher level output of the positioning accuracy by fixing a rod, supporting the stator to freely slide in the axial direction of the rod and applying a current to the coil of each phase wound to the stator to generate a propelling force with a rotary magnetic field generated. SOLUTION: A rotary magnetic field is generated by supplying a command current to the coil of each phase of a stator 11 from a control system. With generation of a rotary magnetic field, an N-pole magnetized band 3 and S-pole magnetized band 4 of a magnetic screw 1 of the male side are attracted and a rotating torque works on the rod 2. However, since the rod 2 is fixed and restricted in its rotation, its rotating torque is transferred as a propelling force in the axial direction for the N-pole magnetized band 3 and S-pole magnetized band 4 of the magnetic screw 1 of the male side spirally magnetized. Therefore, with a clockwise and counterclockwise torque generated on the stator 11 by a current command value, the magnetic screw 1 in the male side linearly moves in the axial direction. Therefore, an output having higher positioning accuracy can be generated.

Filed: 1997-02-04
Abstract: PROBLEM TO BE SOLVED: To extend charge and discharge cycles, reduce the internal resistance of a secondary battery, and enhance the quick charge performance of the battery by using composite particles in which carbon particulates of a specific median diameter are stuck onto the surface of an electrode active material, so as to form conduction paths. SOLUTION: Carbon particulates 1 whose median diameter is 600 nanometer or less, preferably 300 nanometer or less, are adsorbed on the surfaces of electrode active material particles 2, or particles 3 which is produced by the change of the electrode active material so as to form a conductive mesh 4. Since the mesh 4 is formed of the particulates, the same can be freely deformed as keeping a mutual contact on the electrode active material surface with the expansion and contraction of the electrode active material. A charge current flows from a collector 5 through the mesh 4, and it can be inferred that the surfaces of the inert particles are electrolyzed, so that the active material is regenerated. Preferably, the carbon particles 1 have such minute structures such that still further finer particles are linked chain-like.
