Title: Multi-gradation recording method
Inventor: KOBAYASHI TAKESHI
IPC: H04N1/40
Filed: 1989-06-30
Abstract: PURPOSE:To satisfy the visual sense characteristic with less gradation number and resolution than those of a conventional method by adopting a multi-value error spread method to express a picture with the combination of the gradation number and the resolution required to satisfy the visual sense characteristic efficiently and coding the picture data and outputting the result. CONSTITUTION:A data weighted by an error spread table 107 and accumulated is stored in a line buffer memory 108 and accumulated error difference xn and fmn from the line buffer 108 are added by an adder 102. Let the accumulated error be xn and the addition of accumulated error xn to the density data fmn, gmn=xn+fmn is inputted to a multi-value table 103. Then the content of the address pointed out by the data gmn is outputted as a multi-value data Dmn. The result of the data Dmn is multiplied by K at a coefficient device 105, an error en is calculated as en=K.Dmn-gmn at a difference computing element 106 and sent to the error spread table 107. The error spread table 107 uses a spread matrix to give a prescribed weight to the error en and stores the result to the line buffer memory 108.

Title: Scanning tunnel microscope
Inventor: MIKAJIRI AKIO
IPC: G01N37/00
Filed: 1986-07-18
Abstract: PURPOSE:To upgrade the resolution in a horizontal direction, by providing a lens to focus a tunnel electron current. CONSTITUTION:A specimen 8 is scanned in X-direction for a tip 1 and also, in Y-direction by periodical extension and contraction of supporting bars 6a and 6b. As the surface of a specimen is rugged, distance between the tip 1 and the specimen 8 is varied and the tunnel current generated between the tip 1 and the specimen 8 is also varied, but a bar shaped member 2 is extended or contracted by the change of the signal from a control circuit 16 to the bar shaped member 2 so as to compensate the veriation of the distance. In this case, the output signal from the control circuit 16 is sent to a recorder 18 and the signal representing a distribution of ruggedness on surface of the specimen is recorded on the recorder 18. In this time, the tunnel electron current is finely concentrated as it flows in a magnetic field lens L, and a detected signal of the tunnel current which is to be sent to the control circuit 16 carrys information in a narrow range in a horizontal direction. Thus, resolution in the horizontal direction can be upgraded.

Title: Sheet thickness sensing method of image recording device and its means
Inventor: SHU EIFUKU
IPC: B41J25/308
Filed: 1997-06-26
Abstract: PROBLEM TO BE SOLVED: To precisely and automatically sense change of thickness of a sheet by sensing change of reflected light quantity by a reflecting surface to vary in accordance with thickness of the sheet by a reflection type optical sensor. SOLUTION: Reflected light quantity which an optical sensor 140 receives from a reflecting surface 138 is decided by an interval of the reflecting surface 138 and the optical sensor 140 and an inclination of the reflecting surface 138. When a sheet S is inserted between a feed roller 114 and a friction roller 128, one end side of a friction roller guide 130 to which the friction roller 128 is connected is pushed upward by the sheet S, while the reflecting surface 138 on the other end side connected to a spring 132 is pushed downward. As moving quantity at this time is corresponding to thickness of the sheet S, an interval between the reflecting surface 138 and the optical sensor 140 changes in accordance with thickness of the sheet S. Consequently, reflected light quantity which the optical sensor 140 receives also changes proportionally in accordance with thickness of the sheet S.  In such a principle, it is possible to precisely sense change of thickness of the sheet S.

Abstract: PURPOSE:To set initial coordinate values of navigation of an inertia detecting means of a moving body by a method wherein motion of shaking, rotation or the like is given to a moving body from a moving parent body, the motion is detected by the inertia detecting means of the moving body and the moving parent body and a detected value of the moving body is corrected with the detected value of the moving parent body used as a reference. CONSTITUTION:Acceleration is given to an inertial navigation system (MINS) 18 of a missile by shaking or rotating a missile launcher 10 intentionally, and this acceleration is detected by an accelerometer which the MINS 18 has. An inertial navigation system (SINS) 12 is installed in the vicinity of the center of shaking or rotation of the launcher and it can measure the acceleration of the launcher precisely. Based on a detected value of the SINS 12, accordingly, an acceleration vector at the time of roll to be detected at the position of the MINS 18 can be obtained by computation precisely from the relative positional relationship between the SINS 12 and the MINS 18. Three orthogonal coordinate axes of acceleration vectors of the SINS 12 and the MINS 18 thus obtained are compared and a difference value of each coordinate axis is set correctively in the MINS 18 as a corrective value for the MINS 18 and stored therein as an initial coordinate value. Using as references the coordinate values thus obtained, the missile 16 can fly to a target point correctly from a warship 10.

Title: Burnishing device
Inventor: SASAMORI TAKEFUSA
IPC: B24B39/02
Filed: 1982-10-01
Abstract: PURPOSE:To burnish a fixed workpiece by inserting an axially movable rotary tapered rod between several tapered rollers supported by a guide, in a burnishing device for a bored hole surface. CONSTITUTION:With a rod 3 having a tapered end retracted through a piston 8 by feeding a pressure oil through a retracting oil-pressure port 14, several tapered rollers 2 in a group are inserted into the hole of a workpiece 1, in a condition of reduced diameter. Then, with a spindle 18 rotated and with a pressure oil fed through an advancing oil-pressure port 13 and, as the rod 3 is rotated while being advanced, the tapered-roller 2 group is rotated while expanding its diameter, with the outer surface pressed against the machining surface, thereby improving the roughness of the surface. When the burnishing operation is completed, the rod 3 is retracted, allowing the tapered-roller 2 group to be retracted with its diameter reduced. This ability to burnish a workpiece in a fixed condition enables the device to be incorporated in a transfer machine while providing a uniform surface roughness.
