Title: Orthogonal modulator
Inventor: YAMAMOTO HIROYUKI
IPC: H04L27/20
Filed: 1991-10-01
Abstract: PURPOSE:To provide a small-sized orthogonal modulator by simplifying an addition circuit for the transmission of a non-modulation carrier wave signal by providing two selection circuits for alternatively selecting two variable DC voltage generation circuit, a DC voltage signal and a base band signal. CONSTITUTION:When a non-modulation carrier wave is outputted, the output signal of a balanced mixer 7 is outputted as it is via an adder 11 and a non- modulation carrier wave of a constant amplitude is obtained since the output voltage of a balanced mixer 8 also becomes 0 when both of switches 5, 6 are switched to a DC voltage side b, the output of a variable DC voltage generator 1 is defined as the constant amplitude and the output voltage of the other variable DC voltage generator 3 is set to 0. When a modulation wave is outputted, the modulation wave can be outputted in the same way as in conventional orthogonal modulator by setting the both of the switches 5, 6 to a base band signal side a.

Title: Carrier
Inventor: MATSUMURA YASUO
IPC: G03G9/107
Filed: 1987-11-09
Abstract: PURPOSE:To obtain a dispersion type carrier which has less dependency of electrostatic chargeability on environment by incorporating magnetic power which is subjected to a surface treatment by a positive chargeable inorg. material into the magnetic powder dispersion type carrier essentially consisting of a resin and the magnetic powder. CONSTITUTION:The charge control of the carrier for a developer of a magnetic powder dispersion type is executed by using the magnetic powder which is subjected to the surface treatment by the positive chargeable inorg. material. Since the charge control is executed by using the magnetic powder which is the main component of the dispersion type carrier, the control is easier than with the conventional carrier which controls the charge characteristic from the binder resin side by adding additives, etc., to the carrier. In addition, the environmental characteristic of the chargeability is low and the carrier is usable as a long-life carrier. The inorg. materials to impart the positive chargeability to the carrier by the surface treatment are exemplified by magnesium oxide, aluminum oxide, titanium oxide, zirconium oxide, calcium carbide, zirconium hydroxide, calcium tungstate, cobalt carbonate, zirconium hydroxide, magnesium carbide, magnesium hydroxide, etc.

Title: Arrester
Inventor: YAMASHITA MIZUHO
IPC: H02H9/06
Filed: 1991-10-29
Abstract: PURPOSE:To realize the visual detection of ground fault by providing a current transformer for transforming an arrester current, i.e., primary current, into a high secondary current for fusing a part of secondary circuit, and a linear resistor connected in parallel with the current transformer. CONSTITUTION:Upon grounding of an arrester 1, a ground current having power supply frequency flows, as an arrester current, to the ground side of the arrester 1. The arrester current is in the order of 1A which is too low to operate a non-linear resistor 4 and a high current is induced in the secondary circuit by the flux produced at a primary coil section 5. Since the ground current has considerably longer duration than that of lightning current or switching surge, fusible part 8 of the secondary circuit is fused with the energy produced during the duration of the ground current. When a lightning current flows through the arrester 1, a voltage is produced from the primary coil section 5. The voltage is limited by the non-linear resistor 4 connected in parallel with the current transformer 3 thus reducing the flux to be produced in a highly magnetic body 7.
