Title: Charge transfer device and manufacture thereof
Inventor: FUNAKOSHI HIROMASA
IPC: H04N5/369
Filed: 1990-05-16
Abstract: PURPOSE:To increase charge transfer efficiency by providing separating means between a plurality of charge transfer elements and providing an impurity introduction area, at least one side of which is anti-parallel, on a charge transfer electrode inside the charge transfer elements. CONSTITUTION:An N-type impurity which causes an electrical potential to decrease is injected to a hutching of HCCD 27. An effective impurity injection area 1 is formed into a substantially trapezoid, and the distance becomes larger from the HCCD 27 to a separation section 40. An N-type impurity is implanted to the shape of the impurity injection area 1. The electrical potential of that portion becomes high, and charges are attracted to it. Since the electrical potential does not become lower than a portion where the impurity is not implanted through a narrow channel effect appears also in the portion where the impurity is implanted, the wider the portion where the impurity is implanted, the lower the electrical potential becomes. As a result, an electrical potential gradient occur toward below a transfer electrode 29, and the charges can be moved easily in this direction.

IPC: H04M3/42
Filed: 1981-08-17
Abstract: PURPOSE:To obtain an economical outgoing sender by using a storage circuit for called-subscriber's number transmission and a reading circuit in common for sending a calling-subscriber's number. CONSTITUTION:When a sender is acquired by a marker firstly, the marker transfers a called-subscriber's number from a called-subscriber's number transfer circuit BNO to a storage circuit BNOM through a switching circuit CHGO, and a calling-subscriber equipment position signal from a calling-subscriber equipment position transfer circuit SUBO to a storage circuit SUBM. A reading circuit BS reads a called-subscriber number out of the BNOM and then sends it to  an opposite station through a transmitting circuit SND. Then, when the opposite  station makes a request to send the calling-subscriber's number, the sender  clears the BNOM and also starts the marker to transfer information on the  SUBM to the marker. The marker converts the calling-subscriber equipement  position from the sender into a calling-subscriber's number, which is transferred from a transmitting circuit ANO to the BNOM through the CHGO. The BS sends the calling-subscriber's number to the opposite station as well as called- subscriber's number transmission.

Title: Device and method for rubbing long and flexible sheet
Inventor: ITO HIDETOMO
IPC: G02F1/1337
Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To form an orientation film having no defective orientation by making it possible to adjust the inclination of a rubbing roller from its center line by one of carrier rollers for guiding and carrying a long and flexible sheet. SOLUTION: A tensile force measuring instrument is attached to a carrier roller 5b or a rubbing roller 6 to execute carrying or rubbing processing while adjusting the tensile force of a long and flexible sheet in its width direction. A rubbing angle can be adjusted by inclining the roller 6 from the carrying direction of the flexible sheet to its plane direction. After adjusting the rubbing angle, the roller 6 is rotated in the reverse direction at a fixed rotational speed while carrying the sheet by a carrier device at fixed tensile force and fixed speed, so that rubbing can be continuously executed. Since continuous rubbing makes it possible to carry the sheet in a floated state by an air foil effect, the sheet is not moved in the width direction and rubbing can be stably and continuously executed.
