Filed: 1984-11-09
Abstract: PURPOSE:To make a flicker inconspicuous by setting the period of the same pixel driven by the same polarity over 1/30 seconds as well as in case of 240 pieces of panel lines at the time of alternative drive of liquid crystal even in case that high resolution is planned, for example, considering the numbers of LCD panel lines as 480pcs. CONSTITUTION:One gate line 43 for applying a common timing signal to each TFT2, 2... gate corresponding to all the segment electrodes 1, 1... belonging to the adjacent to two line unit is lined. Out of the two line unit, the image signals of the odd field to drain line 31 corresponding to the odd line, of even field to drain line 32 corresponding to even line are applied respectively. The applied image signal is turned reversely in its polarity 1 field just like that fact that the odd field is of positive polarity and the even field is of negative polarity. When a timing signal is applied to the gate line 43 (one horizontal scanning period), etc. unit display element (composing one pixel) of two line portions is simultaneously driven. The period of the same element driven by the same polarity becomes 1/30 seconds, e.g., one frame period.

IPC: F15B11/048
Filed: 1996-09-09
Abstract: PROBLEM TO BE SOLVED: To provide a hydraulic cylinder snap device of type not provided in a hydraulic cylinder. SOLUTION: A pilot operated control valve is provided, which has a prescribed snap position formed so that a flow discharged from an operating chamber of a hydraulic cylinder 16 must be made to pass through a plurality of slow speed limiting orifices in a valve spool 22.

Abstract: PURPOSE:To unflod a tent and fold it to make it small by one man's handling, by attaching a plurality of circular struts made of narrow spring members to a tent cloth as a unit. CONSTITUTION:Circular struts 3... made of narrow spring members are attached to a tent cloth 2 as a unit.

Title: Scanning tunneling microscope
Inventor: KAINO MASATOMO
IPC: H01J37/28
Filed: 1994-10-03
Abstract: PURPOSE: To obtain a scanning tunneling microscope in which the influence of a noise is reduced by a method wherein a probe is connected to the intermedi ate layer of a bipolar transistor and one of other layers is used as the output end of an amplified tunnel current. CONSTITUTION: A bipolar transistor 3 constitutes a grounded-emitter transistor amplifier circuit. When a voltage is applied across a sample 1 and a probe 2 by a bias power supply 6, a tunnel current Jt flows to the direction of the probe 2 across the sample 1 and the probe 2. In the transistor 3, the current Jt becomes a base current, and a current which has multiplied the current Jt by hfe is output to an emitter. The tunnel current which has been multiplied by hfe is converted into a voltage by a preamplifier 5, and, after that, the same processing operation as a scanning tunneling microscope in conventional cases is performed. Since the probe 2 and the transistor 3 are installed so as to be adjacent, the length of a route into which a noise creeps with reference to the tunnel current picked up by the probe 2 becomes short, and the creeping degree of the noise is reduced.
