Title: Multicolor image forming device
Inventor: SUZUKI KAZUO
IPC: B41J2/525
Filed: 1997-07-03
Abstract: PROBLEM TO BE SOLVED: To provide a compact and inexpensive multicolor image forming device having no trouble that a previously developed and formed image is made irregular at second and succeeding developing time and the thinning of density or positive fogging is not caused at second and succeeding developed images without depending on the kind of a photoreceptor and the ability of a re-electrifier. SOLUTION: The photoreceptor is electrified to +400 V so as to perform 1st exposure and the surface potential of an exposure part is attenuated to +50 V so as to form a 1st electrostatic latent image. Then, 300 V developing bias voltage is impressed to perform reversal development for the exposure part. By impressing 500 V higher than 400 V being the target potential of a 2nd developing position, re-electrification is performed. At such a time, a 1st developing part is electrified to 400 V. Furthermore, exposure larger by the amount of exposure to attenuate a 1st developing non-image part by 100 V is performed to a part where 1st image information is off. Next, 300 V developing bias is impressed to perform the reversal development.

CONSTITUTION:One thread sandwiching piece 10 is arranged in each interval between respective projecting pieces 82 and the lower edge of this sandwiching piece is caused to be the circular arc shape of a thread holder 9. Then, an upper surface contacts with a slanting surface 92 and the thread edge is sandwiched by the slanting surface 92 and the lower edge of the thread sandwiching piece. When only a needle stick in the constant position, in which the sewing or embroidery is executed, is lifted, a projection 13 to release the thread sandwiching by the thread sandwiching piece is provided only in the constant position and held to a receiving stand 5 by vises. This projection 13 turns a needle stick fitting plate 2. Then, when the desired needle stick is caused to be in the constant position, the tip of the projection 13 presses the back of the plate spring made thread sandwiching piece 10 so that the sandwiching can be released for the thread edge to be passed through the needle in this constant position. When a needle plate fitting plate is turned and gets out of the constant position, pressure is released by the projection 13 for the thread sandwiching piece and the thread edge is sandwiched by the elasticity.

Abstract: PROBLEM TO BE SOLVED: To provide a teletext receiver and a method with which teletext data can be reproduced and viewed together with video signals without damaging the intrinsic convenience of character broadcasting capable of turning on/off the display of superimposed characters. SOLUTION: The video signals of television broadcasting, on which teletext data provided by a tuner 3 are superimposed, are sent to a changeover switch 4 and a scanning line exchange part 15. A control decoding part 8 performs decoding processing concerning the teletext data from an error correcting part 7, sends these data to a display control part 10 and sends data to be recorded to a reconstitution part 14. The reconstitution part 14 transforms the data from the control decoding part 8 to a format to be superimposed on a scanning line again and sends these transformed data to the scanning line exchange part 15.  Corresponding to a synchronizing signal from a synchronizing separating part 5, the scanning line exchange part 15 receives the data from the reconstitution part 14 and exchanges data on the scanning line of video signals from the tuner 3 with the data from the reconstitution part 14 so that a signal for recording for a video tape recorder 2 is generated and outputted. Therefore, the teletext data can be reproduced and viewed together with the video signals.

Abstract: PROBLEM TO BE SOLVED: To efficiently produce a high grade single crystal by performing uniform sublimation of a raw material throughout the whole of a raw material part, efficiently generating the sublimated gas and reducing the fluctuation with time in generation of the sublimated gas. SOLUTION: In this production, when charging powdery SiC used as the constituent material of a raw material part 2 into a crucible 1, powdery SiC to be placed in the surface section of the raw material part 2, being in contact with a space part 3, and a section in the vicinity of this surface section, is selected so that it consists essentially of large particles having 500 to 1,000 μm particle size and contains no small particles having <=250 μm particle size. Since such large particles of powdery SiC are hardly sintered, the sublimation of powdery SiC at the bottom of the raw material part 2 is not inhibited and spaces through which the sublimated gas can be passed, are formed among these particles. Thus, uniform and efficient sublimation of the raw material powdery sic can be attained throughout the whole raw material part 2.
