Title: Liquid crystal display device driven by thin film transistor
Inventor: KABUTO NOBUAKI
IPC: G02F1/1368
Filed: 1987-06-22
Abstract: PURPOSE:To extend the life of a liquid crystal panel by forming drain bus driving means for impressing an image signal with positive polarity to a half of picture element electrodes and impressing an image signal with negative polarity to the residual half and serially floating an opposite common electrode. CONSTITUTION:The drain bus driving means 41, 42 for uniforming the number of picture elements with positive polarity in an image signal impressed to a picture element driving electrode S and the number of picture elements with negative polarity to almost the same number are used and the opposite common electrode 14 is serially floated. Since no external DC voltage is applied from the external to the electrode 14, DC potential is determined by an orientation film constituting a quid crystal cell 5 and the leakage of a liquid crystal material. Since the number of display signal impressing picture elements having positive polarity and the number of picture elements having negative polarity are almost equal at optional time, the potential of the electrode 14 goes to its average voltage and a liquid crystal cell 5 of each picture element is completely driven by AC. Since the potential of the opposite common electrode 14 can be set up to the optimum value without using a capacitor having a capacity value more than required capacity and executing adjustment the life of the liquid crystal panel can be improved.

IPC: G11B20/12
Filed: 1986-06-30
Abstract: PURPOSE:To reproduce normal data by surely detecting an SYNC outputted from a SYNC area and an address mark. CONSTITUTION:Data recorded in the SYNC area on a magnetic recording medium are detected based on read data RD and an operation permission signal for a PLL circuit is outputted in accordance with said detection. An address mark in an address mark area on the magnetic recording medium is detected by an address mark detecting circuit 31 based on the outputted data pulse. After a prescribed time from the detection of the address mark, an operation disable signal having a fixed pulse width corresponding to the output time of the read data corresponding to a gap area of the magnetic recording medium from a magnetic head is outputted. At the time of said output, the output of the operation permission signal for the PLL circuit is stopped to stop the outputs of a data pulse and a clock pulse from the PLL circuit. Since the SYNC and the address mark can be surely detected from the SYNC area, always normal data reproduction from the data area can be attained.

IPC: B22D41/54
Filed: 1993-06-24
Abstract: PURPOSE:To prevent or reduce the clogging of a molten metal pouring nozzle when the Al-deoxidized molten metal is poured by specifying the composition of the nozzle for pouring the molten metal and the apparent porosity. CONSTITUTION:When the molten metal of the total oxygen content T.O>=5ppm is poured, the internal-mounting type or integrated type nozzle for casting has the composition consisting of, by weight, 70-95% Cab, and the balance one or more kinds of Al2O3, SiO2, MgO, Cr2O3, ZrO2, and C, and the apparent porosity is <=50%. In addition, as required, the waterproof resin is coated on the nozzle surface. The heat shock resistance and the spalling resistance can be improved by using the nozzle having such composition.
