Title: Developing device
Inventor: KASAI TOSHIHIRO
IPC: G03G15/08
Filed: 1986-10-28
Abstract: PURPOSE:To prevent the generation of fogging or uneven density and to improve picture quality by rotating a feed roller consisting of a fibrous brush in the vicinity of a developing roller. CONSTITUTION:When the feed roller 72 in a toner box 67 serving as a housing for storing nonmagnetic one-component toner 66 is rotated in an arrow Z direction at about twice the rotational speed of the developing roller, toner 66 in the vicinity of the roll 68 is stirred and triboelectrified to positive polarity by a triboelectrification sequence with the fibrous brush 72a. On the other hand, the feed roller 72 removes old toner 66 applied to the surface of the roller 68 and carries new toner 66 triboelectrified to positive polarity at a coating blade 70 side. Since the negative polarity component of the new nonmagnetic one-component toner 66 is reduced even immediately after feeding the toner 66 into the toner box 67, fogging on a printed image can be reduced and a distinct and excellent image can be obtained.

Title: Tortion crystal vibrator
Inventor: KAWASHIMA HIROFUMI
IPC: H03H9/19
Filed: 1992-09-25
Abstract: PURPOSE:To provide a compact low frequency crystal vibrator which excels in the frequency temperature characteristic by using a U-shaped vibrating arm connected to a support part through one of both ends of the arm. CONSTITUTION:One of both ends of each of U-shaped vibration arms 2 and 3 is connected to a support part 4. Meanwhile the free ends of both arms 2 and 3 are set adjacent to each other. In such a constitution, the length of each vibrating arm is substantially increased. Thus a vibrator of the low frequency is obtained. Furthermore the size of each arm can be reduced in its lengthwise direction owing to its U-shaped structure. Thus a microminiature tortion crystal vibrator is obtained by a chemical etching process with the excellent impact resistance. When this vibrator is made of a plate obtained by turning the Z-plate crystal by 25 deg.-30 deg. around an axis X and then by 5 deg.-20 deg. around an axis Z', the absolute value of a secondary temperature coefficient beta is reduced down to about 1/2 compared with a bending mode crystal vibrator.
