Patent JP-H02271541-A (JP)
Title: Charge transfer device
Inventor: KURODA TAKAO
IPC: H01L29/762
Filed: 1989-04-12
Abstract: PURPOSE:To obtain a high transfer efficiency by a method wherein a width of a transfer channel is narrowed to a prescribed width at a plurality of parts inside a prescribed length and an effective boundary part of transfer electrodes is formed on a part where the width of the transfer channel has been narrowed. CONSTITUTION:A width W of a transfer channel 1 is narrowed at a plurality of parts (1a to 1c); a width which is narrowed at one part is set to a prescribed width or lower; a prescribed width W' which is required as a whole is set. An effective boundary part of transfer electrodes 2a to 2c, 3a to 3d is formed on a part where the width of the transfer channel has been narrowed. When the width is narrowed at the plurality of parts in this manner, a required width can be narrowed as a whole; a potential barrier by a narrow channel effect is caused at the plurality of parts at the boundary of the transfer electrodes 2a to 2c, 3a to 3d; different voltages are applied to the transfer electrodes in the plurality of parts during a transfer operation. Thereby, since an influence of the narrow channel effect can be eliminated, a high transfer efficiency can be obtained.

IPC: G01C9/12
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a panel inclination detecting device which is capable of effectively detecting the swing of a panel when the panel is swung with a degree greater than a predetermined value during its travelling. SOLUTION: In such a case that a panel is swung by a degree greater than a predetermined value, a relative inclination of the panel 3 is detected, with respect to a pendulum member 15 always directed, perpendicular to the ground surface (floor surface), and accordingly, an absolute inclination can be surely measured. Since the control is made in such a way that the deflection of the panel 3 is restrained in response to a signal corresponding to the detected value, the panel 3 is prevented from running with deflection of a degree which is greater than a predetermined value, thereby it is possible to stably run a running device in the upper part of the panel 3.
