Title: Cam groove structure for driving lens of optical device
Inventor: KABE EIICHI
IPC: G02B7/04
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To prevent a backlash in a photographic area between cam grooves formed on the inner surface of a lens barrel and cam pins linked with a lens by making the depth and width of each cam groove in a non-photographic area greater than the depth and width of each cam groove in the photographic area, in a lens-driving cam groove structure in which the cam pins are guided by the cam grooves and moved. SOLUTION: Cam grooves 1b, 2b corresponding to the non-photographic areas of cam grooves 1, 2 are greater in depth and width than cam grooves 1a, 2a corresponding to the photographic areas of the cam grooves 1, 2, and the projected lengths of input pins guided into the cam grooves 1, 2 are adjusted relative to the cam grooves 1a, 2a corresponding to the photographic areas. Thus, a backlash between the cam grooves 1a, 2a corresponding to the photographic areas and the input pins can be minimized.

Title: Magnetic head positioning device
Inventor: SEO YOUSUKE
IPC: G11B21/10
Filed: 1983-05-18
Abstract: PURPOSE:To position a data head with a high accuracy by placing the data head and a servo-head so that the servo-head exists in a specified area against other data zone, when the data head coincides with a data. CONSTITUTION:A data head 12 and a servo-head 13 are loaded on a slider 11, and a data recording zone 14 and an erasing zone 15 are shown on the disk surface. Also, when the data head coincides with on the data recording zone, the servo-head is placed so as to be laid across the erasing zone and the data zone. Therefore, at the time of a track following operation, an output of the servo-head is servo-operated so as to hold a constant voltage. In this case, when correcting an output variation of a film thickness variation, a radial position, etc., an output of an automatic gain adjusting circuit of a signal of the data head 12 can be utilized since the servo-head 13 exists in the vicinity of the data head 12. In this way, a servo-signal having a linear relation against a position shift is obtained without requiring a special servo-pattern, therefore, the head is positioned with a high accuracy.

Title: Paper sheet conveying device
Inventor: SHIMOOOSAKO MASATAKA
IPC: B65H7/08
Filed: 1994-04-25
Abstract: PURPOSE:To prevent skewing between a sheet of paper and a register roller couple by bringing the leading edge of each sheet into contact with a stopper, and feeding the sheet to the register roller couple while a deflection is generated in the sheet. CONSTITUTION:A copying machine is equipped in its body with a sheet conveying path 13, through which sheets of paper P are conveyed, and a stopper 15 capable of elevating and sinking for supplying the sheets P to a register roller couple 14 and stopping there. When a sheet P is conveyed into the path 13, the leading edge comes in contact the stopper 15 and a deflection is generated. The stopper 15 and the path 13 move toward the register roller couple 14 while maintaining the deflected condition of the sheet P. When the stopper 15 is displaced to the retreat position, the sheet P is set off from the stopper 15 and conveyed toward the register roller couple 14. This prevents a skew from recurring during the period from the sheet P being set off from the stopper 15 to reaching the register roller couple 14.

Thus, the anchor effect between organic substances 2 increases, and the adhesive strength with the organic substance 2 is improved; and the durability of an ultrasonic wave probe is improved, and the bending resistance of a piezoelectric vibrator is improved, so that the deformation into a complicated shape such as a concave surface can be performed. At the same time, the diameter of the rod 1 is varied along the longitudinal axis, so that the resonance in the rod 1 in radial vibration mode being unnecessary vibration mode is suppressed.  Further, only the vibration mode of the longitudinal axis of the rod 1 is generated and the vibration is excited as a piezoelectric vibrator only in the thickness direction.
