Abstract: PURPOSE:To easily transfer conductive toner to recording paper, by directly transferring a toner picture formed on a picture forming body to a recording medium by softening and melting the toner by heat through the recording medium and permanently fixing the picture to the recording medium with fixing roller. CONSTITUTION:A toner picture is formed with conductive toner on a photosensitive belt 4 by a simultaneous method and the moved photosensitive belt 4, on which the toner picture is formed, is contacted with a recording medium 17 fed in the direction shown by the arrow 19 by means of carrying rollers 18. At the time when the belt 4 is contacted with the medium 17, the conductive toner receives heat from a heat roller 20 through the recording medium 17 and part of the toner is softened and melted. The melted toner is transferred to the recording medium 17 because the sticking force of the melted tonerr to the recording medium 17 becomes stronger than the electrostatic force which confines the conductive toner to the belt. The toner picture formed on the recording medium 17 is fixed and the medium 17 becomes a printed matter when the medium 17 is passed through fixing rollers 21. The printed matter thus produced is discharged in the direction shown by the arrow 22.

Abstract: PURPOSE:To prevent an ohmic electrode from being deteriorated when a large electric current flows by a method wherein a wiring metal layer is laminated in such a way that it nearly coincides with a front edge of the ohmic electrode. CONSTITUTION:A conductive layer region 1 is formed on a semiinsulating semiconductor substrate; an N<+> layer to be used as a substratum of ohmic electrodes 2 is formed. A heat treatment is executed in order to activate the N<+> layer; after that, an ohmic electrode metal layer composed of an AuGe alloy is applied. The N<+> layer and the ohmic electrodes 2 are connected by regions (resistance- interohmic connection regions) 4. Then Ti, Pt and Au are laminated and formed one after another as wiring metals. During this process, parts of wiring parts 3 opposite to conductive layer resistances are formed in such a way that front edge parts nearly coincide with front edge parts of metal parts of the ohmic electrodes 2. According to the electrode wiring parts, the ohmic electrodes 2 and the wiring parts 3 are in a nearly perfectly laminated state at the front edge parts opposite to the resistance layers; accordingly, a cross-sectional area in a current route is large; even when a large electric current flows, a deterioration is not caused.

Voltage detectors 40-60 are connected respectively between the inverter output lines 101-103 and the output 100 of the potential divider 2. Hereby, when the output voltage of the inverter part becomes larger than the output voltage of the potential divider, a control command is output to a controller to control upper and lower arms short circuit time, thus the GTO arm short circuit prevention time can always stably be secured.

Title: Pseudo noise code synchronizing circuit
Inventor: NAKAMURA MASARU
IPC: H04J13/18
Filed: 1990-06-15
Abstract: PURPOSE:To enable high-reliability synchronization without generating imbalancing correlation outputs by obtaining a required phase comparing characteristic close to phase difference '0' by correlating with a Manchester coding pseudo noise code. CONSTITUTION:Since a PN code is formed to be a Manchester code, one correlation device 24 can obtain a control signal required for a voltage control clock generator 1. Namely, a DS diffusion signal and the Manchester-coded PN code are multiplied by a multiplier 29, and integrated by an integrator 30 to calculate correlation and only by passing the result through a loop filter 10, a phase locked loop can be constituted in using the result as the control signal of the voltage control clock generator 1. In such a case, since the peak of correlation is generated at a position shifted from the phase difference '0' for almost 2DELTA/3, for the demodulation, it is enough only to obtain the correlation between the PN code, which is shifted only for 2DELTA/3 phase by a 2DELTA/3 delay circuit 31, and the DS concrete signal.
