Title: Image display method electro-optic device
Inventor: YAMAZAKI SHUNPEI
IPC: G02F1/133
Filed: 1991-06-07
Abstract: PURPOSE:To obtain a precise gradational display with a suppressed influence of variance among elements by controlling the width of pulses when the pulses are applied to a liquid crystal material at such a period that the liquid crystal material does not respond. CONSTITUTION:When twisted nematic liquid crystal is used, for example, when the period of pulses is set to 1msec in a figure (a), a gradational display which is the brightest with A and gets darker in the order of B, C, and D is displayed. The concrete principle is not known in detail yet. When, however, the pulses are applied to the liquid crystal material at the period in which the liquid crystal material does not respond, the width of the pulses is controlled to obtain intermediate density under digital control. The period of the pulses for obtaining the intermediate density like this is <=10msec in case of the twisted nematic liquid crystal. This control can be performed by connecting the output terminal of a deformed buffer type circuit in which an N type and a P type thin film transistor act complementarily to a liquid crystal pixel electrode.

Title: Discharging method for large lump in reducing rotary kiln
Inventor: YATSUNAMI KAZUHARU
IPC: C21B13/08
Filed: 1978-12-29
Abstract: PURPOSE:To make it possible to draw off large lumps in a rotary kiln while operating the rotary kiln without use of manpower or mechanical power, by controlling suitably the quantity of reducing agent and the rotating speed. CONSTITUTION:To a rotary kiln 1 which normally rotates at a rotating speed 0.6- 1.0rpm is fed green pellets 1b having been dried, preheated, and hardened in a preheater 2. Simultaneously, a reducing agent such as coal is charged from a feeder set to the lower part of an after-burner 3 at a rate about 0.45Cfix/Fe. The green pellets are reduced with reducing agent while being rolled in a mixed state to form CO, H2, which are burned with supplied air 4 and are directed to a discharging outlet 1a. When large lumps are formed in the kiln 1 during the operation, the reducing agent is remarkably increased temporarily to 0.60-1.00Cfix/Fe, and the rotating speed of the kiln 1 is notably decreased to 0.1-0.4rpm. As a result, large lumps in the kiln 1 are moved in the direction of the outlet 1a and are drawn off easily and suitably to the outside.
