Title: Electromagnetic induction apparatus
Inventor: MIZUNO HIROKAZU
IPC: H01F27/36
Filed: 1978-02-20
Abstract: PURPOSE: To prevent local heating with reduction in the stray loss with a magnetic passage formed on the wall surface of the vessel as opposed to the iron core through the coil by sticking magnetic metal thereto.  
     CONSTITUTION: A coil 1 wound around an iron core is housed in a vessel made of a magnetic metal. A magnetic path material 7 made of a magnetic metal is stuck to form a magnetic passage on the wall with accumulated magnetic flux of the vessel as opposed to the core through the coil. With such an arrangement, the increase in the magnetic passage by the magnetic path material 7 can reduce the flux density B6 while the amount ϕ5 of the magnetic flux passing the opposed section 3a remains large as before. The resultant reduction in the stray loss prevents the local heating of the vessel.

Title: Pressure transferring method for pulverulent toner image
Inventor: OZAKI NOBUHIRO
IPC: G03G15/20
Filed: 1980-02-18
Abstract: PURPOSE: To obtain a pressure trasnfer system which transfers pictures excellently with superior transfer efficiency, by performing pressure transfer while providing an image carrier with lubricity to an image transfer material to some extent by using a lubricant.  
     CONSTITUTION: Through pressure roller 10 of collection box 22, a prescribed amount of lubricant 20, such as phthalic acid, is applied on the surface of photoreceptor drum 6 of the image carrier and during pressure transfer, the extent of sliding of at least ≥2mm is generated for each recording paper, etc., of 300m in length as an image transfer material. This sliding prevents the occurrence of the filming phenomenon of photoreceptor 6 and also reduces the force of friction between the surface of drum 6 and pulverulent image toner to expand the transfer range, so that the occurrence of detection in transfer will securely be prevented. Thus, the pressure transfer system can be realized which can transfer excellent pictures efficiently with small pressure. Axes of drum 6 and roller 10 are crossed at an angle of 0.5W2.0° to generate sliding to required extent.

Title: Ofdm receiver
Inventor: SEKI TAKASHI
IPC: H04L27/26
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration in a bit error rate by reducing a common phase error(CPE) and inter carrier interference(ICI) due to a phase noise. SOLUTION: After a received orthogonal frequency division multiplex(OFDM) signal is converted into an IF band by a tuner 101 and a local oscillator 102, the signal is converted into a digital signal by an A/D converter 103 and is, converted into a complex base band signal by an IQ demodulator 104. Then a phase noise suppression circuit 105 detects phase fluctuations of an input signal to correct them thereby suppressing a phase noise in the local oscillator 102. An FFT circuit 106 obtains received data of each sub carrier from the output through an FFT processing for a valid symbol period in one symbol period. Since a phase noise of the local oscillator 102 is reduced by the phase noise suppression circuit 105 before the FFT processing, both CPE and ICI are reduced in the output of the FFT circuit 106.  An output of the FT circuit 106 is given to a demodulation circuit 107, where a QAM signal sent through each sub carrier is demodulated.
