Title: Voltage controlled oscillator
Inventor: MURAKAMI NORIO
IPC: H03B5/32
Filed: 1995-07-24
Abstract: PROBLEM TO BE SOLVED: To extend the variable range of the VCO(voltage controlled oscillator) oscillation frequency and to improve the stability of oscillation against the high frequency. SOLUTION: The capacitance value of a variable capacitor 38 is set by a capacitor control means, and a crystal vibrator 37 vibrates with the frequency accordant with the set capacitance value. The vibration of the vibrator 3 is amplified by an NMOS 31 and this amplification result is amplified by a PMOS 32. These amplification results are fed back to the input side by the capacitors 35 and 36, and the oscillating actions are carried on. Thus an output signal of the oscillation frequency accordant with the control voltage is outputted from an output node N12. The source 31S and the back gate 31B of the NMOS 31 are connected in common to each other and therefore the voltage gain coefficient of the source-follower of the NMOS 31 is equal to about 1. Then the capacitance value is reduced less when it is viewed from the gate 31G of the NMOS 31.  As a result, the variable range of the capacitor 38 can be extended.

Title: Josephson voltage standard device
Inventor: YAMASHITA TSUTOMU
IPC: H01L39/22
Filed: 1980-12-29
Abstract: PURPOSE:To generate a constant DC voltage which has a wide operating current range easily with high stability by a method wherein a direct current and a high frequency current are supplied directly to one Josephson-element in a super- conducting closed circuit. CONSTITUTION:One Josephson element J1 and N Josephson elements J2 are connected in parallel to compose a super-conducting closed circut. In this closed circuit, when a direct current I and a high frequency current i are supplied simultaneously to the parallel junction point of the element J1 and the elements NXJ2, a relation Y1+NXY2=O is realized, where Y1 and Y2 are the phase of the current through the element J1 and the elements NXJ2 respectively. And the phase roration of the current through the elements J2 is slower than that of the current through the element J1 by 1/N of that value. Then the DC constant voltage generated by the elements J2 has a wide current range corresponding to the integer N. Thus, by increasing the number N of the elements J2, the constant DC voltage which has a wide operating current range can be generated easily with high stability.

Abstract: PURPOSE:To miniaturize the circuit by decreasing the number of connecting lines and elements by providing plural coincidence circuits for detecting the coincidence of each bit output of parallel data which have been read out to a data bus by a control circuit and a 1-bit output of picture element data. CONSTITUTION:Picture element data of plural bits for showing a designated color or gradation is set to a register 10, and when a read-out request is issued once from a CPU 1, a plane component of an (m) picture element portion is read out to data buses 5, 6 by a time division, respectively from a graphic memory 2, and in (m) pieces of coincidence circuits 1700-1715, the coincidence with each plane component of picture element data which has been set to the register 10 is detected by a time division at every plane. In this state, if a component which does not coincide exists even one among all the plane components, in holding circuits 1900-1915 of the (m)-picture element portion, a result of discrepancy is held in the holding circuit corresponding to its picture element. In such a way, the number of connecting lines and the number of coincidence circuits are decreased, and the circuit can be miniaturized.

Title: Transformer
Inventor: URATA SHINYA
IPC: H01F27/34
Filed: 1999-07-01
Abstract: PROBLEM TO BE SOLVED: To enable a transformer to be lessened in loss, improved in efficiency, and reduced in cost, size, and weight by a method wherein the coil of a transformer is equipped with a primary and a secondary winding, the windings are concentrically wound on an iron core, a sheet-like electric wire is used as one of the windings, and a structure member which holds the interior of the transformer is formed of non- magnetic material. SOLUTION: A transformer is equipped with an iron core 1 and a primary and a secondary windings 21 and 22 where the windings 21 and 22 are concentrically wound on the core 1, and a sheet-like electric wire is used as either of the windings. A three-phase penta-pod iron core transformer is equipped with the iron core 1 formed of amorphous magnetic material, where a coil bobbin 23 is provided as a structural member to the inner circumference of the coil, and coil pressing metal pieces A31 and B32 are arranged as structural members on the outer periphery of the coil. The structural member located inside the coil are formed of non-magnetic material, and the structural members located outside the coil are formed of magnetic material. Therefore, an eddy current hardly flows, and the transformer can be lessened in eddy- current loss.  As a structural member inside a coil is formed of non-magnetic material, the structural member is hardly affected by a leakage magnetic flux, and an eddy current can be lessened even if a structural member is formed of magnetic material.

Title: Self-holding type switch matrix
Inventor: JINNO MASABUMI
IPC: H03K17/60
Filed: 1988-07-27
Abstract: PURPOSE:To realize the simultaneity of states of all switches by arraying the switch provided with a gate input terminal, a switch circuit and a control terminal like a two-dimensional matrix. CONSTITUTION:When a trigger signal is applied to a gate input terminal G, a base current flows and the first transistor Q1 becomes ON, and its collector current is fed back to a base of the first transistor Q1 by the second transistor Q2, therefore, even if the trigger signal annihilates, a state of ON is maintained. Also, when some voltage is applied in advance to a control terminal C which has been connected to an emitter of the first transistor Q1, even if the trigger signal is applied, said transistor does not become ON since a base current does not flow, and when a higher voltage is applied, said transistor becomes ON and the first and the second transistors which have been brought to self- holding can be reset to OFF. In such a way, each of the switches have been arrayed like a two-dimensional matrix can be held in a desired state, and the simultaneity of all the switches can be realized.
