Title: Driving method for liquid crystal matrix panel
Inventor: FURUBAYASHI YOSHINORI
IPC: G09G3/36
Filed: 1990-07-20
Abstract: PURPOSE:To drive a liquid crystal matrix panel at high speed and with high operating margin by including a pulse voltage with reverse polarity and less than a threshold voltage before or behind the pulse voltage when the pulse voltage higher than the threshold voltage of liquid crystal is included in a pulse voltage group which sets the liquid crystal at a prescribed state. CONSTITUTION:The pulse voltage group which sets the liquid crystal at the prescribed state is applied before a selection period in spite of display data. When the pulse voltage with a peak value higher than that of the threshold voltage of the liquid crystal is included in the pulse voltage group, the voltage with the reverse polarity to that of the pulse voltage and the peak value less than that of the threshold voltage of the liquid crystal can be included before or behind the pulse voltage. Thereby, since only two states of voltage impressed to a scanning electrode are set the same time, the constitution of a driver is simplified, and the liquid crystal matrix panel with high operating margin is driven at high speed even with the driver for liquid crystal responsible to an effective value.

Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To stably obtain an AIN sintered compact having high thermal conductivity by incorporating a surfactant into a green compact and adjusting the content of C in a degreased compact with the C derived from an org. component at the time of calcining the green contact contg. AlN and the org. component. SOLUTION: The AlN sintered compact is obtd. by degreasing and calcining the green compact consisting of an inorg. component consisting essentially of AlN power and the org. component consisting essentially of an org. binder. At this time, the surfactant is incorporated into the green compact as the org. component and the content of the C to be present in the degreased compact is adjusted by the carbon derived from the org. component described above without separately adding the carbon. The surfactant is used in combination as the org. component constituting the green compact, by which the dispersibility of the org. component in the green compact is improved and the carbon derived from the org. component existing in the degreased compact is highly dispersed. The AlN sintered compact having the high thermal conductivity is thus stably obtd.

Abstract: PURPOSE:To quickly prevent a filler from fuming or exploding, by providing an auxiliary winding covered with a material which is melted by heat generated during short circuit of a load, the auxiliary winding being mechanically contacted with a heavy load winding so that the heavy load winding is short circuited when the auxiliary winding is short circuited. CONSTITUTION:A light-load secondary winding 10 is constituted by a wire covered and insulated with a material thermally melted, while an auxiliary winding 11 is constituted by an open wire or wire covered and insulated with a material thermally melted. The winding 11 is adapted to be mechanically contacted with a winding 10. If any defect is caused in a load 21 and the load is short circuited, the winding 10 generates heat and layer-short circuited. The short circuited section of the winding generates more heat, by which the winding 10 is also contacted electrically with the winding 11. The heavy-load secondary winding 9 thereby provides a closed circuit. As a result, large current flows through a primary winding 8 to actuate an overcurrent protection device 14. In this manner, a filler can be prevented from fuming or exploding.

Title: Method for charging sealed type lead-acid battery
Inventor: SHIOMI MASAAKI
IPC: H01M10/44
Filed: 1994-07-26
Abstract: PURPOSE:To enhance the cyclic lifetime characteristics of a battery to a great extent by sensing the battery temp. prior to the start of charging, and starting the charging with a current according to the sensed temp. so that the current is greater with higher temperature. CONSTITUTION:The relationship between the temp. T deg.C and the current I (in CA's) in the initial period of charging (first stage) is calculated for the purpose of attainment of a long lifetime, and therefrom Formula I is obtained. A temp. sensor is previously put in a battery, and the temp. of the battery is sensed. The first stage charge current is determined through calculation by substituting into formula I the internal temp. of the battery measured prior to the start of charging. The second stage charging is made by setting the current to 3.15 A, and charging is conducted until the total charge amount becomes 105% of the rated capacity. The operation is stopped when the specified value is exceeded by the temp. difference between any plural pieces of the group of batteries, and the charge is resumed when the temp. difference becomes below the specified value. Thus the battery lifetime characteristics are enhance by heightening in this manner the current in the initial period of charging with increasing battery temp. and also setting a limit on the temperature.
