Title: Method for automatically controlling depth of soil movement and grading
Inventor: KURISUTOFUAA OO MIDORUTON
IPC: E02F9/20
Filed: 1989-06-09
Abstract: PURPOSE: To control depth of a blade by constituting a grader to compensate for the variation in the height of a standard surface, as it moves along the standard surface by reflecting a ranging pulse transmitted from an acoustic transceiver on the standard surface. CONSTITUTION: An acoustic chirp is transmitted from a transducer of a follower 10, when a control box 80 is powered up. Thereafter, the total required time for the acoustic chirp to return to the follower 10 after reaching a standard surface 170 and reflected on it is detected. Additionally, a microprocessor controls the height of a blade by using a time value and locks the blade to a desired position. The follower 10 continues to transmit acoustic chirp and detects a change of the standard surface 170 when a grader 30 is driven. Furthermore, when the standard surface 170 is raised, a follower circuit detects this, transmits a signal to a hydraulic valve system 70, raises a blade 40 and a frame 20 and keeps a prescribed distance between the follower 10 and the standard surface 170.

IPC: G09G3/36
Filed: 1997-05-22
Abstract: PROBLEM TO BE SOLVED: To obtain uniform light emission quantity for each pixel and each panel and to improve picture definition. SOLUTION: A controller 2 stores a binary picture signal in one frame unit. The controller 2 divides one frame into plural sub-frames showing a picture to be displayed in two-level picture data based on values of each digit of a picture signal of stored one frame. This two-level picture data for each sub- frame is written in a capacitor Cp from a drain driver 4 for each line. When the picture data is '1', a transistor for driving 12 is turned on. A common driver 5 applies voltage of the prescribed level for each sub-frame, and controls voltage applied between electrodes of an organic EL element 11. Thereby, the organic EL element 11 emits light with different brightness for each sub-frame. Pictures of each sub-frame are synthesized visibly, and gradation in one frame is expressed.

Title: Color thermosensitive recording
Inventor: NISHIMURA TOMOYOSHI
IPC: B41J2/325
Filed: 1995-06-15
Abstract: PURPOSE: To prevent density variation from occurring by moving a color thermosensitive recording material in relation to a thermal head, in such a state that the former is pressed by the latter, then causing the thermal head to help the color thermosensitive recording material move, under the pressed state, to the recording start position of an printing area, and preheating the thermal head by a bias thermal energy during the assisted movement under pressure. CONSTITUTION: When recording data in yellow, for example, the number of motor drive pulses is counted from the time of detecting a position for the tip of a color thermosensitive recording material 1 by a sensor located upstream in close proximity to a thermal head for Y 18. If the counted number reaches a specified value and immediately after the thermal head for Y 18 is set to a position for the beginning of an assisted movement under pressure, the thermal head 18 is pressed against the color thermosensitive recording material 1 through a pressing mechanism. A microcomputer 32 for printing control for Y preheats the thermal head 18 referring to a ROM 42 for preheating, upto a position for starting the recording in a printing area. After that, the microcomputer records a thermal image referring to a ROM 41 energization control 41.  For the remainder of the operation, each line is thermally recorded sequentially while a platen drum 10 is intermittently rotated by a specified amount to feed the color thermosensitive recording material 1 for one line.

Filed: 1990-06-07
Abstract: PURPOSE:To prevent a fall of snow by mounting a face member having a number of projections for positively catching the snow landed on the surface and preventing its fall onto the surface of a steel tower member. CONSTITUTION:On one side surface of a face mounting body 10 such as metal band, rubber or plastics, projections 11 of a length, thickness and form easy to catch snow are formed.

Title: Resin enclosed semiconductor device
Inventor: TOYODA MINORU
IPC: H01L23/28
Filed: 1981-09-21
Abstract: PURPOSE:To manufacture a high quality resin enclosed semiconductor device with excellent moisture resistance subjected to no shortcircuit trouble by a method wherein the periphery of fine metal wire and the surface of electrode of semiconductor chips are covered with the resin different from the conventional enclosing resin. CONSTITUTION:The permeating route of water content from the surface of enclosing resin 7 may be assumed to be two kinds, i.e. the first route directly reaching the oxide insulating film 2 from the surface of enclosing resin 7 as shown by the arrow mark A while the second route reaches the surface of the polyamide base resin 8 covering the periphery of the fine metal wire 6 from the surface of enclosing resin 7 and then reaching said oxide insulating film 2 of the semiconductor chip along the interface of said enclosing resin 7 and said polyamide base resin 8 as shown by the arrow mark B. However, the permeated water content can not reach the electrode 3 since the surface of electrode 3 and the periphery of fine metal wire 6 are covered with said polyamide base resin 8. Therefore the breakdown around the electrode due to water content and the shortcircuit trouble of fine metal wire in case of resin enclosing may be entirely prevented.
