IPC: H04N5/66
Filed: 1993-08-06
Abstract: PURPOSE:To realize alignment of visual line and to improve the picture quality of a display screen in the display image pickup device used for a video telephone system or a video conference system. CONSTITUTION:An optical deflection element 3 whose transparent state or reflecting state is selected with respect to an incident light is arranged in front of a display device 1 and an image pickup device 2 in a way that the display device 1 is observed in the transparent state and the image pickup device 2 picks up the image of the user M in the reflecting state. Either of the two states of the optical deflection element 3 is switched in time division at a shorter interval than one frame period by a controller 5 and the image pickup device 2 is controlled in the reflecting state to pick up an image of the user M. Thus, it is possible to pick up the image of the user M from the direction of observing the display and a picture in which visual lines of the users are aligned is displayed and picked up. Furthermore, since the display is observed in the transparent state, no picture quality deterioration of the display screen is caused and the method adopts the display device of any kind.

Filed: 1987-08-07
Abstract: PURPOSE:To prevent the change of the surface layer of the ground into damp ground when the level of groundwater rises by forming a soil cement water- permeable wall at the upper part. CONSTITUTION:The portion to be the upper part of an underground wall 1 is excavated while injecting cement milk containing a blowing agent and the portion to be the lower part is excavated while injecting only cement milk. Since excess water permeates the upper soil cement water-permeable part of the underground wall 1 when the level of groundwater rises, the change of the surface layer and adjacent area into damp ground and the spouting of groundwater from the ground's surface, as in the conventional cases, can be prevented.

Title: Cushion controlling unit of hydraulic actuator
Inventor: HARA SADAAKI
IPC: F15B11/00
Filed: 1984-09-20
Abstract: PURPOSE:To reduce the manufacturing cost and enable the cushion effect of being set arbitrarily by controlling a controlling spool on the bases of a signal related to a displacement of the controlling spool and another signal related to a pressure at the return side of a hydraulic actuator. CONSTITUTION:A signal (y) related to a displacement of a controlling spool of a cushion valve D and a signal P2 related to pressure at the return side of a hydraulic actuator S are sent to a speed sensing circuit VD. The speed- related signal generated from the speed sensing circuit VD is integrated by an integrating circuit 39 to determine a cushion stroke position. Said signal is then sent to a target opening memory circuit MC and a target opening displacement memory circuit HC to determine a target displacement of the controlling spool. The target displacement is compared with an actual displacement. On the basis of the comparison result, the controlling spool is controlled. The need for a small diameter chamber and a cushion ring will therefore be eliminated, on account of which manufacturing cost can be reduced and the cushion effect can be arbitrarily set.

Title: Radio control device
Inventor: NARIYA GIICHI
IPC: A63H29/22
Filed: 1998-07-13
Abstract: PROBLEM TO BE SOLVED: To provide a radio control device equipped with a D/R function that can switch a rate by a simple operation not damaging the operability of a stick. SOLUTION: An adjustment value (rate) that determines the relation between a manipulated variable of a stick and an amount of motion of a servomotor may be switched at the point of switching optionally set optimally within the range of manipulated variables of the stick. A rate 1 is 100% and a rate 2 is 60%. A point 1 is set at a position of about 65% of the maximum value for the right direction (or downward direction) of the manipulated variable of the stick. A point 2 is set at a position of about 85% of the maximum value for the left direction (upward direction) of the manipulated variable of the stick. If the manipulated variable of the stick is relatively small, the effectiveness of steering is low at the point 2. However, when the point 2 is exceeded, the effectiveness of steering is improved to the rate 1.  The servo can be operated greatly by a small amount of operation of the stick.

Abstract: PURPOSE:To make measurement more accurate free from errors due to own gravity of an object to be measured, by a method wherein the object being measured hangs horizontally and with the movement there4of locked at two fulcrum points, a horizontal load is applied at the center of the fulcrum points to measure deflection. CONSTITUTION:An object 10 to be measured hangs horizontally by four string members 16 suspended from a ceiling 18. Fulcrums 12 are provided at two points separated by l to keep the object 10 being measured from moving backward. Then, a load W is applied in the direction of the arrow at the midpoint between the fulcrums 12 to measure deflection delta of the object with respect to the resulting changes. Rigidity EI is calculated from the deflection delta by EI=l<3>W/48delta. This enables accurate measurement free from deflection due to the own gravity of the object 10 being measured.
