IPC: E21B10/32
Filed: 1991-11-22
Abstract: PURPOSE:To excavate a large size plate-form groove, by inserting an excavator into a small hole with a small inner diameter in the state that an expansion arm is retracted to the main body side and expanding the expansion arm to rotate a cutter. CONSTITUTION:After a pilot hole 42 has been bored by a drill to make a specified depth, the drill is pulled out and expansion type excavator 1 is suspended in the state that expansion arms 10, 10 are drawn in to position along the main body 2 and inserted in the pilot hole 42. Next, the main body 2 is fixed so as to be fitted in a freely rotatable rotary table and a plurality of ring-form stabilizers are provided on a protection wall so that the main body 2 can slide. Then the expansion arms 10, 10 are completely expanded through a hydraulic jack 6 for expansion, a slide ring 7, etc., while a rotary cutter 20 is driven to rotate and excavate the ground to form a groove 59 having almost the same width with the expansion arm. After the expansion arm has been extended completely, the ground is cut down vertically to form the groove 59 to the depth corresponding to the lowermost level of a storage cave.

Title: Image forming device
Inventor: MIZUMA TAKASHI
IPC: G03G15/08
Filed: 1987-12-29
Abstract: PURPOSE:To form an image of a specified area speedily and clearly by cutting off the voltage of a roller when toner is attracted to a latent image in the specified area and applying the voltage to the roller when toner is attracted to a latent image in an unspecified area. CONSTITUTION:An upper roller developing bias switch 9 turns off to stop the application of the developing bias to the upper roller 15 when the toner is attracted to the latent image formed on the drum surface of a photosensitive drum in the different-gradation area inputted from an operator panel 1 and turns on to apply the developing bias when the toner is attracted to the area other than said different-gradation area. When the voltage of the upper roller 15 drops to 0V, the attraction of the toner to the photosensitive drum is excel lent because of the potential difference between the upper roller 15 and photosen sitive drum and the image formed on transfer paper becomes sharper. Further, twice transfer is not required like superposition and the different-gradation is transferred at a time, so the transfer is speeded up. Consequently, the image of the specified area is formed speedily and sharply.

Filed: 1989-12-26
Abstract: PURPOSE:To reduce base resistance and leakage currents between an emitter and an epitaxial layer by bringing a base layer in high concentration near to an emitter and surrounding the periphery of the emitter by the base layer. CONSTITUTION:A P-type diffusion layer 112 as a high-concentration base layer is formed on the surface of all base region except a section just under a polycrystalline silicon layer 109a, and an emitter diffusion layer 113 is surrounded by the high-concentration base layer. A high-concentration base layer 404 is formed onto the surface of a base diffusion layer 403. Consequently, the threshold voltage of a parasitic MOS is increased, MOS operation is prevented, and leakage pass from the region of an epitaxial layer 402 to the region of an emitter 401 is inhibited. Accordingly, base resistance can be lowered and leakage currents between the emitter and a collector suppressed.

Title: Image forming device
Inventor: OHORI AKIRA
IPC: H04N1/40
Filed: 1992-11-20
Abstract: PURPOSE:To prevent copying and to use a print for other general use even when discrimination is in error by receiving read picture data so as to discriminate whether or not a color original picture is a specific original whose copy is inhibited and converting picture data of only a prescribed area when the original is discriminated to be a special original thereby preventing copying. CONSTITUTION:RGB picture data outputted by reading an original at an image scanner 101 are processed for various picture processing by a picture processing circuit 102 and a special original discrimination section 103 discriminates whether or not the original is a special original simultaneously. When the original is discriminated to be the special original, an area recognition section 104 recognizes a picture area to be a cause of the discrimination and outputs an area signal and the discrimination section 103 outputs a discrimination signal to an adder section 105. The adder section 105 adds a prescribed value to an output signal of the circuit 102 only in an area represented by the area signal when the discrimination signal indicates the special original and outputs the sum to a laser printer 106. Thus, only a copy inhibit part of the original is colored and other parts are copied as they are to prevent illegal copying and even when the discrimination is in error, the copy print is used for general use.

At the time of the losing, the lower two digits of the random number based on the counted value of the counter 40 are displayed as the display pattern. At the time of not the high probability, corresponding to a similar procedure, based on the pattern group for the standard probability, the winning and the losing are displayed by three-digit display.  In such a manner, the display is changed depending on whether it is the high probability or a low probability and the high probability is really felt.

Title: Method for bringing probe of probe microscope nearer to sample
Inventor: MORIMOTO TAKASHI
IPC: G01N37/00
Filed: 1993-12-28
Abstract: PURPOSE:To provide a method by which the probe of a probe microscope can be safely brought nearer to a sample in a short time without causing the probe to collide with the sample. CONSTITUTION:A sample 4 set on a sample stage 5 is observed under an optical microscope 10. A probe 1 is positioned within the visual field of the microscope 10. A Z-axis displacing mechanism 2 moves the probe 1 in the vertical direction and a lifting/ lowering mechanism 11 moves the microscope 10 in the vertical direction. The image of the sample 4 obtained through the microscope 10 is displayed on a display device 14 by means of a CCD camera 12 and picture processor 13. When the probe 1 is brought nearer to the sample 4, the microscope 10 is displaced to the position where the microscope 1 is focused on the probe 1 and another position where the microscope 10 is focused on the sample 4 and the distance between the two positions is found. Then the probe 1 is brought nearer to the sample 4 based on the distance and, thereafter, the probe 1 is slowly brought nearer to the sample 4 until the probe 1 reaches a point at a prescribed distance from the sample 4. Since the distance between the probe 1 and sample 4 can be made extremely short in the first approaching operation, the overall moving time of the probe 1 can be remarkably reduced.

Abstract: PURPOSE:To eliminate a complicated control for the diffusion and the concentration of dots, to prevent also the occurrence of the problem of an error accumulation, and to obtain a further smooth output result whose resolution is high. CONSTITUTION:A picture output device 1 outputs entire colors which can be expressed in a 2X2 mesh as a test pattern 2. The test pattern 2 is read by a picture inputting device 3, an RGB value is found and an averaged LUT 4 is prepared. Then, uniform picture data 5 in which (i)X(j) picture elements are all equal colors are prepared for the entire number of the colors to be expressed, each picture element is corrected by adding an average with weighting of the error of the picture element for which the peripheral processing is operated at every picture element and 5-ary encoded. Then, the next error is searched from the 5-ary encoded picture element by referring to the averaged LUT 4. This is operated to an (i)X(j) range, the mean value of the obtained 5-ary encoded data is found and registered in a three-dimensional color correction table 9. Thus, the correction values of the entire colors to be expressed are registered in the three-dimensional color correction table 9 by repeating this processing. The color correction is operated by using the three-dimensional color correction table 9, so that a binarization processing can be operated independently of the color correction processing, and the binarization processing by dot units can be attained.
