CONSTITUTION:Terminals of all (N) scan bus lines (SB) on a substrate are connected commonly with a high resistant material (HRP) of linear pattern and an electric voltage so high as (N-1) times of an impressed voltage V0 to 1 TFT is impressed at a same time from a power source PW to both ends of HRP. In this stage, the impression of the DC-voltage (N-1)V0 is done arrang ing a bus line connected with a gate electrode of TFT to a positive electrode side and a bus line connected with a drain electrode to a negative electrode side. Thus, the voltage V0 is impressed at the same time, to the gate electrode and the drain electrode of TFT, and sufficient amt. of electron necessary for shifting a threshold voltage to a positive direction is injected into a gate insula tion film. Thus, a TFT substrate of a gate-connected opposed matrix type is completed by removing HRP thereafter.

On both ends of the frames 2, 2, propeller type vanes 3, 3 are mounted vertically in parallel with the rotational axis 4. In this windmill, the vanes 1, 1 receive resistance at first and start at low rotational speed. Along with the start of rotation, a peripheral speed ratio increases on account of a difference between rotation radii of the vanes 3, 3 and it becomes suitable for the high efficiency conditions of Darius type vanes. Accordingly, this windmill implements both low peripheral speed operation of the Saponius type and high speed peripheral operation of the Darius type. Also with a relatively flat structure for horizontal rotation, it can be mounted on a roof easily.

IPC: G06F3/02
Filed: 1978-10-30
Abstract: PURPOSE: To ensure an accurate reception of the data information at the reception side for the device which transmits and receives the key input in the wireless method, by inserting the redundant code of two bits between the bits of the key input information.  
     CONSTITUTION: The redundant code of two bits of 10 or 01 is inserted into the bits of the input information of keyboard KU at transmission part 1. At the same time, start signal SS of a longer period than one-bit period of the input information plus end signal ES are added before and after the key input data in order to modulate carrier fC such as the infrared rays and the like from light emission part LS. Carrier fC is modulated by the signals f 1  and f 2  corresponding to 1 and 0 of the key input information and then transmitted. The infrared rays emitted from the transmission part are received at reception part 2 and by sensor LR, and the information given from keyboard KU is displayed on the TV picture receiver. Thus an accurate data reception is possible through detection of the redundant code between the data bits even though some timing shift may exist between the one-bit transmission time of the transmission side and the data detection of the reception side.

Filed: 1990-05-25
Abstract: PURPOSE:To reduce a data transmission time by decoding received picture information by one line repetitively for the count when a same line is consecutive in the received picture information to form a reception picture. CONSTITUTION:At first, the operator uses a host equipment HST to generate a transmission original and informs the fact of transmission to a facsimile adaptor FAX. The FAX calls a noticed destination to prepare the picture infor mation transmission and makes a request of the transfer of picture information by one page to the equipment HST. The equipment HST makes raster conver sion to a transmission original comprising generated character strings to gener ate a picture data and codes and compresses the picture data in the unit of lines and transfers the result to the FAX in the unit of lines. In this case, the equipment HST monitors the consecutive same line and when the same line is consecutive, only a line synchronizing signal representing a delimiter of one line of picture information is transferred to the FAX. Upon the receipt of the picture information comprising only the line synchronizing signal from the equipment HST, the FAX sends the picture information of the line entered just before comprising not only the line synchronizing signal to a destination facsimile equipment as the picture information of the line.
