Title: Semiconductor memory
Inventor: KANEKAWA RYOJI
IPC: G11C11/414
Filed: 1986-10-22
Abstract: PURPOSE:To shorten an access cycle by executing the charge extraction from a released word line based on a constant reference voltage, and shortening the time necessary to make the charges of the preceding selected word line come exactly in a non-selected state. CONSTITUTION:The differential circuit 7 of a drive circuit 6 detects the potential of a word line W. The reference voltage is higher than the potential of a word line in a non-selected status, and lower than the middle level between the word line potentials in a selected-and-driven status and a non-selected-non-driven status. A current flowing into the differential circuit 7 is taken out by a current mirror 8, and supplied to a charge extraction circuit 10 as a drive voltage through an emitter-follower 9. The circuit 10 is turned on and driven while the potential of a word line W is higher than the reference voltage, during which time, a current  Ist is drawn from the word line W through a word fly-back line IST. As a result, the charge extraction from the preceding word line W1 selected can be continued even after the time when the line potential of the line W1 comes lower than that of the word line W2 of current selection.

Filed: 1990-09-18
Abstract: PURPOSE:To maintain a polarizing plate and a liquid crystal panel at temperature less than useful temperature extending over the entire length in a running direction by reducing the cross-section of the passage of a cold blast along the running direction. CONSTITUTION:Air ducts 30, 31 through which the cold blast 40 passes are provided between the liquid crystal panel 20 and the polarizing plates 10, 11, and the cross- sections of the passage of the air ducts 30, 31 are formed so as to be reduced directing from an input side to an output side. In other words, the cold blast 40 sent to the air ducts 30, 31 runs at flow velocity V1 proportional to a wind-volume/passage cross- section at the input side by forming the air ducts 30, 31 whose passage cross-sections are reduced directing from the input side to the output side of the cold blast 40 between the polarizing plates 10, 11 and the liquid crystal panel 20, and the passage cross-section of the air ducts 30, 31 are reduced at the output side, therefore, the cold blast runs at high flow velocity V2. Therefore, the temperature of the cold blast 40 is increased in the neighborhood of the output side by receiving heat, however, the reduction of thermal conductivity can be canceled. Thereby, the polarizing plates 10, 11 are the liquid crystal panel 20 can be maintained at temperature less than the useful temperature without generating temperature nonuniformity.

IPC: C25D5/50
Filed: 1988-10-05
Abstract: PURPOSE:To prevent diffusion of tin and copper and to improve resistance to thermal peeling properties by plating lead on copper and copper alloy and thereafter plating tin thereon and furthermore heat-treating the plated layer to alloy one part or all parts thereof.
