Title: Supporting structure of optical rotary joint
Inventor: TAKIZAWA KATSUTOSHI
IPC: G02B6/40
Filed: 1994-06-01
Abstract: PURPOSE:To prevent misalignment of the optical axis of an optical rotary joint. CONSTITUTION:While the fixing end 50a of the optical rotary joint 50 is loosely fitted to a fixing member nonrotatably and by having a play in a radial direction, the rotatable turning end 50b of the optical rotary joint 50 is engaged with a supporting frame 42 rotatably integrally therewith and by having a play in a radial direction.

Title: Charge transfer device having branch transfer channel
Inventor: SUZUKI NOBUO
IPC: H01L29/762
Filed: 1977-10-07
Abstract: PURPOSE:To manufacture the charge transfer devoce making unnecssary for CP selection, by driving all the transfer electrodes with the same CP, through the provision of the control electrode at the inlet of branch path. CONSTITUTION:The control electrode 19 is kept at the DC voltage Vc1 which is intermediate value of CP amplitude, and the voltage Vc2 of the control voltage 20 is kept the same as that of the substrate. With three phase CP, the charge under the transfer electrodes is moved from the input section 11 to the output section. But, the potential well of intermediate value is always caused under the electrode 19 and no well is present under the electrode 20, the charge under the transfer electrode 12c is fed under the electrode 16a and delay by 3 cells can be made. By taking Vc1 the same as the substrate and Vc2 as the intermediate voltage of CP, the transfer path under the electrode 19 is turned off, and the charge under the electrode 12c is fed under the electrode 13a via the semi-closed channel under the electrode 20 and 5 cell delay is made via the branch path B. Thus, the channel selection is made possible only with the voltage set of the electrodes 19 and 20 and all the transfer electrodes are fed by CP at all times, then the dark current signal component stored in the output section 18 is not fluctuated.
