Title: Recorder
Inventor: OCHI HIROSHI
IPC: G03G15/09
Filed: 1977-09-22
Abstract: PURPOSE:To make possible recording of high densities at a high speed as the resistance of toner layer becomes low at the charging and the resistance becomes high after the charging by applying picture signal voltages at the boundary part of the compressing region and releasing region of the toner layer. CONSTITUTION:A recording head 20 which plays the action of a compressing plate constitutes a multi-stylus head 22 on the surface of an insulation type support plate 21 and in a recordig region 9 the spacing is limited by the head 20 and sleeve 6. In a compressing region 31, the toner layer 4' is compressed and therefore the resistance value is small. In a release region 32, the compression is released and the end 33 of the multi-stylus head 22 positions at the boundary part of both regions 31, 32. When picture signal voltages 7 are applied while subsequently switching the electrodes 22, the toner 4 of the position 34 opposing as the charges of the polarity opposite from that of the applied voltages are injected from the face of the sleeve  6. Thereby, recording of high speed and yet high densities may be obtained.

Title: Winding tension controller for tire component member
Inventor: HIRAI TAKAYUKI
IPC: B29C53/80
Filed: 1988-05-10
Abstract: PURPOSE:To provide preferable controlling accuracy, responding accuracy of winding tension, frictional durability and to improve control by pulling a tension roller by a timer composing member to accelerate it to the moving speed of the member, regenerating a current generated in a DC motor at a power source side, and applying a brake force to the motor to generate a tension of the value equal to an applied tension value in the same member. CONSTITUTION:Regenerative control means 28 transmits a tension signal to a DC motor 29 to control the rotary speed of a DC motor 29. A tension roller 9 is so rotatably driven that its peripheral speed becomes a speed slower by a predetermined speed than the molding drum moving speed of a tire component member 4. Since no slip occurs between the member 4 and the roller 4, the roller 9 is pulled by the member 4, and its peripheral speed is so accelerated to become equal to the moving speed of the member 4. As a result, the motor 29 is forcibly accelerated to be rotated to generate a current corresponding to the acceleration. A tension of the value equal to the applied tension therein is operated at the member 4 by a resistance generated when the motor 29 is accelerated.

Abstract: PURPOSE:To reduce the deformation of a character by moving each vector for forming a character to the outside or the inside of the character in accor dance with an offset value given from the outside and changing the line width of the character to be printed. CONSTITUTION:A given offset value is divided by 2 and the offset value W(W=N/2) is calculated. First, each vector forming a character is moved by W in parallel to the direction where its line width is widened. Thus, P1 P2 is moved to P1s P1e, P2 P3 to P2s Pe, P3 P1 to P3s P3e, P4 P5 to P4s P4e, P5 P6 to P5s P5c, P6 P4 to P6s P6e, respectively. The crossing point of the straight lines of the vectors P1s P1e and P2s P2e is made to P2 and this coordinate is calculated. Six vectors of P1' P2' to P5' P6' whose crossing points are connected in sequence become vectors for forming characters whose line width is widened by 2W.
