Title: Method for driving liquid crystal display device
Inventor: KAWACHI YUJI
IPC: G02F1/133
Filed: 1992-08-19
Abstract: PURPOSE:To prevent a liquid crystal from deteriorating and a display from becoming defective by holding the 2nd layer metal of an additional capacitance or semiconductor thin film at the same potential as a substrate electrode potential on a liquid crystal layer. CONSTITUTION:A thin film transistor(TR) constituting an active matrix liquid crystal display device has the additional capacitance composed of an insulating film 12 between a 1st layer semiconductor thin film 11 and 2nd layer metal or the semiconductor thin film 11 on a liquid crystal lower substrate. In the 1st layer semiconductor thin film 11 of the additional capacitance, impurity atoms are present even in the lower part of a 2nd layer semiconductor or the metallic thin film 13. Then, the device is driven by holding the 2nd layer electrode 13 of the additional capacity at the same potential as the potential of the upper substrate electrode of the liquid crystal layer. Consequently, even if a short circuit is generated between the 2nd layer electrode and 1st layer electrode of the additional capacitance, the potential of a pixel electrode has no DC potential difference from the liquid crystal layer upper substrate electrode. Therefore, the partial deterioration of liquid crystal and a defective mode such as a stain on a display can be prevented.

Filed: 1997-08-01
Abstract: PROBLEM TO BE SOLVED: To smoothly carry out connection/disconnection between a socket main body and a plug main body by forming a folded part in the connection part between a sleeve and the base end of a claw member in a fluid coupling in which the claw member is engaged in a recess part of the plug main body when the plug main body is inserted into the socket main body. SOLUTION: When an insertion cylinder part 12 of a plug main body P is inserted into a connection cylinder part 4 of a socket main body S, a circular arc upper part 12a in the insertion cylinder part 12 collides against a claw part 8 of a claw member (n) at first, and when the insertion cylinder part 12 is pushed into the connection cylinder part 4 further, a sleeve 5 is moved against a compression spring 6 by means of the pushing force, while the claw part 8 is retracted from a guide hole 10 at the same time. If the insertion cylinder part 12 is pushed into the connection cylinder part 4 to the further extent, the claw part 8 is dropped in a recess part 13.  In this process, as a U-shaped folded part 7 is arranged in the connection part between the claw member (n) and the sleeve 5, the folded part 7 can be bent easily when the sleeve 5 is slid, so that the sleeve 5 can be slid smoothly.

Abstract: PROBLEM TO BE SOLVED: To permit a manager separated from a server to reset the server where a fault occurs by means of receiving warning by receiving plural communication protocols transmitted from a terminal separated from a server controller through the use of a communication unit and responding to one character which identifies one communication protocol by means of a processor connected to the communication unit. SOLUTION: A controller memory 32 is realized in PCB of the server controller in the same way as detection logic so as to include plural buffers. Display data transmitted to the controller memory 32 is stored in a local frame buffer and it is stored at every frame. A local processor 34 in the server controller 26 recognizes the communication protocol transmitted through the use of a state machine being exclusive for the respective protocols. The state machine judges whether the communication protocol is the one based on a text, a PPP protocol or a standby PPP protocol.

Title: Number-of-rotation detector
Inventor: UEDA TOSHITSUGU
IPC: G01B7/00
Filed: 1986-09-19
Abstract: PURPOSE:To reduce manufacturing cost by reducing the chip size of a magnetic bubble element, by calculating the number of rotations of a rotary shaft from the transmission number of times required in the movement of the magnetic bubble on a transmission loop to the position of a magnetic bubble detector by a magnetic bubble transmission means. CONSTITUTION:When the initial position of a magnetic bubble is set to P0, the magnetic bubble is successively transmitted to P1, P2 corresponding to the rotation of a rotary shaft. Now, when a magnetic bubble transmission means 4 is driven to continue transmission until the magnetic bubble is detected by a magnetic bubble detector, the original position of the magnetic bubble, that is, the number of rotations of the rotary shaft 1 up to that time can be calculated from the transmission quantity at that time. For example, when it is supposed that the magnetic bubble is present at the P1-position by one rotation of the rotary shaft 1, the magnetic bubble reaches a P4-position by the transmission of three times by the magnetic bubble transmission means 4 to be detected by the detector D2. Therefore, from the relation between the transmission quantity '3' at that time and the arrangement position P4 of the detector D2, the original position P1 of the magnetic bubble is calculated and the number of rotations '1' of the rotary shaft 1 are obtained.
