Title: Magnetic core for power source line filter
Inventor: OKAMURA MASAMI
IPC: H01F41/02
Filed: 1986-06-04
Abstract: PURPOSE:To remove a noise voltage other than a prescribed power source voltage when the power source voltage is inputted from a power source line to an apparatus, by using a magnetic core for a power source line filter of which the direct-current rectangular ratio obtained when a magnetic field of prescribed magnitude is impressed on the magnetic core is in a certain range. CONSTITUTION:A magnetic core for a line filter, made of an amorphous alloy, is so prepared that the direct-current rectangular ratio Br/B10 thereof is invariably in the relationship of 25%<=Br/B10<=50% when a magnetic field of 10 Oe, for instance, is impressed on the core. Br denotes a saturation flux density, and B10 a flux density obtained when the magnitude of the magnetic field is 10 Oe. The pulse attenuation power of an iron core is the largest in the above range, and it decreases when Br/B10 becomes too high or too low. By selecting Br/B10 in the abovementionde range, accordingly, a noise voltage other than a prescribed power source voltage can be removed when the power source voltage is inputted from a power source line to an apparatus.

Abstract: PURPOSE:To reduce noise by providing a clamp circuit and an offset adjustment circuit and providing an error for each line from a clamp reference value obtained from a horizontal synchronous signal period of a MUSE signal to the offset adjustment circuit. CONSTITUTION:A video signal comprising a luminance signal and a chrominance signal is reproduced from a MUSE signal by a video signal processing circuit 3. An offset adjustment circuit 7 provides offset data to the video signal outputted from the circuit 3 for the adjustment of luminance and hue of the video signal. On the other hand, a clamp data generating circuit 4 detects the clamp reference level of the MUSE signal to generate clamp level data and a clamp circuit 5 clamps the MUSE signal based oh the level. Then clamp error data for each line detected by the circuit 4 are given to the circuit 7. Thus, there is no time difference between the error data from the circuit 4 and the video signal reproduced from the MUSE signal and correction on a specific line is attained.

Filed: 1994-06-10
Abstract: PURPOSE:To obtain a toner fixable at a low temp., free from the problem of offsetting property and excellent in fixing strength to transfer paper by incorporating hexamethylenetetramine and specified novolak type phenolic resin. CONSTITUTION:At least hexamethylenetetramine and novolak type phenolic resin having 50-100 deg.C softening point are incorporated into an electrophotographic toner. The phenolic resin is represented by the formula. In the case of <50 deg.C softening point, the softening point of the resulting toner itself lowers, the blocking resistance is deteriorated and a problem to preservability is caused. In the case of >100 deg.C, the melting start temp. of the toner rises and low-temp. fixability is not ensured. The phenolic resin itself can be used as a bonding resin in the case of noncontact heat fixation. In the case of hot roll fixation, the phenolic resin is incorporated by 5-100 pts.wt. per 100 pts.wt. bonding resin.
