Title: Drilling device
Inventor: ONO ICHIJI
IPC: E21B4/06
Filed: 1995-07-20
Abstract: PROBLEM TO BE SOLVED: To improve workability by providing a skid base with a suspension leader operated by a winch and pin-supporting the leg of the leader to be freely inclined. SOLUTION: A down-the-hole hammer 8 is rotated by an auger 7 and the auger 7 is lowered by a winch 6 to drill with the dead weight of the hammer 8. When the auger 7 is removed from a guide rod 3 for a leader 2, a drilling center can be offset. When right and left supporting rods 4 are expanded at the same length by a hydraulic cylinder 5, the front and rear inclination of the leader 2 is adjusted and, when the right and left expansion of the rod 4 is differentiated, the right and left vertical adjustment of the leader can be made. In case of two or three point drive of a pile, a skid base 1 is towed by a winch or, etc., and freely moved. In this way, a drilling device can be moved even in a narrow site with a small turn, the leader can be vertically set up at a scaffold, if inclined, and the down-the-hole hammer can be used there.

Title: Method and device for converting picture density
Inventor: SEKINE HIROSHI
IPC: H04N1/387
Filed: 1993-08-06
Abstract: PURPOSE:To prevent the generation of a pseudo contour at a gradation part and to eliminate the blurring at an edge part. CONSTITUTION:When a multilevel digital picture is inputted from a picture memory 1, a calculation part 2 obtains the pixel position after the density conversion. Based on the pixel position, a blocking part 3 reads out the picture elements to interpolate the picture elements after density conversion from a picture memory and selects the picture element required to calculate the converted picture element by the primary interpolation method. A calculation part 4 obtains the maximum and minimum values of the blocking picture element and an edge detection part 5 detects the edged part based on the dimension of the difference. Based on the primary interpolation method 6, the interpolated picture element value is calculated. Based on the adjacent interpolation method 7, the interpolated picture element value is calculated. A pattern matching part 10 collate the block pattern binarized by a binarization part 9 with the picture element position after the density conversion. When the coincident pattern is found from the result, a selector 12 is operated by the edge detection from the edge detection part so as to switch it to the 1st or 2nd interpolation method 6 or 7. Thus, the interpolated picture element is calculated.

Title: Video camera
Inventor: NINOMIYA KUNIO
IPC: H04N5/335
Filed: 1988-08-31
Abstract: PURPOSE:To prevent sag, etc., from being generated by a noise with the operation of an electronic shutter by using the rectangular wave of timing to be almost same as that of a transmission pulse, which vertically transmits the accumulating charge of a solid image-pick up element, as a clamp pulse. CONSTITUTION:In a pulse mix circuit 8, a vertical transmission pulse Pi is inputted to a diode 11, detected and goes to be a CP2 pulse. A clamp pulse CP1 is inputted to a diode 12 and the pulses CP2 and CP1 are mixed. Such a mixed pulse is sent to a clamp circuit 5 as the new clamp pulse and clamp processing (picture processing) is executed. In such a case, since a noise part in the vertical transmission period of a solid image-pick up element output is strongly clamped by the wide width pulse of the pulse CP2, clamp operation is early stabled and a video signal, during a V-blanking period, goes to be stable. Then, the sag is prevented from being generated.

Filed: 1990-08-15
Abstract: PURPOSE:To fix the painting quality independently of a teacher by converting the average of position data of point data in a work coordinate system to the average in a data coordinate system and storing it in a locus data storage device. CONSTITUTION:An arbitrary coordinate system data generating device 5 generates coordinate system data of a work based on plural data which are taught with a robot 6 by the teacher and are not on the same plane of the work. A first arbitrary coordinate transformer 7 converts data of the data coordinate system for painting, which is stored in a locus data storage device 4, into data of the work coordinate system based on data of the device 5. A space coordinate average arithmetic device 8 calculates the average of transformed position data. A second arbitrary coordinate transformer 9 converts the average of the work coordinate system into the average of the data coordinate system and stores it in a locus data storage device 1. Thus, positional deviation due to shake or teacher's hands is corrected.

IPC: G03G5/14
Filed: 1985-09-27
Abstract: PURPOSE:To have a surface layer which is transparent, has excellent lubricity and release characteristic of the surface and extremely good cleanability by incorporating a specific polymer obtd. by copolymerizing a specific modified silicone and compd. having a polymerizable functional group. CONSTITUTION:This image holding member contains the silicone comb type graft polymer obtd. by copolymerizing the modified silicone which is the resultant product of condensation reaction of the silicone selected from formulas (I), (II) and the silicone expressed by formula (III) and the compd. having the polymerizable functional group. The amt. of the silicon comb type graft polymer to be added is adequately 0.01-10% based on the solid component weight of the surface layer. The substantial effect of reforming the surface is not obtainable if the amt. of said polymer to be added is <0.01%. On the other hand, the graft polymer exists not only on the surface of the coated film but also in the bulk thereof and therefore, whitening arises from the cause of compatibility with a resin and photoconductive resin which are the essential component of the surface layer and the accumulation of the residual charge arises when electrophotographic processes are repeatedly executed if the amt. exceeds 10%.

Title: Piston device for internal combustion engine
Inventor: SEKIYA YOSHIKI
IPC: F02F3/00
Filed: 1994-09-12
Abstract: PURPOSE: To reduce oil consumption in a piston device for internal combustion engine. CONSTITUTION: An oil ring groove 10 is formed as a stepped groove having a small width groove 10b provided in a ring form on the lateral middle part of the inner bottom part. The groove width of the small width groove 10b is set slightly larger than the diameter of a coil expander 3b, so that an oil ring 3 is never collided with the small width groove 10b by the behavior change of a piston 9. On the piston 9 circumferential wall part corresponding to the thrust-anti-thrust direction of the piston 9 in the small width groove 10b of the inner bottom part of the oil ring groove 10, a slit having the same width as the small width groove 10b and extending through the piston 9 circumferential wall is formed.  Since the capacity of the oil ring groove back clearance part can be suppressed to the minimum by forming the oil ring groove 10 into such a stepped groove, the oil stayed in the oil ring groove back clearance part is reduced, and the flowing quantity of the oil can be reduced to significantly reduce the oil consumption.

Title: Method for measuring internal strain of alumina ceramics material
Inventor: WADA TOSHIAKI
IPC: G01N21/21
Filed: 1989-08-23
Abstract: PURPOSE:To directly measure the internal strain of an alumina ceramics sample without contact by measuring the phase difference DELTA of the above-mentioned sample by a polarization analysis method and contrasting the measured value with the reference value of the phase difference DELTA which is set by the previously determined correlation between the internal strain and phase difference DELTA of the sample. CONSTITUTION:The phase difference DELTA of the alumina ceramics sample which is precisely polished to <=50Angstrom  surface roughness is first estimated by the polarization analysis method. This measured value is then contrasted with the reference value of the phase difference DELTA set by the previously determined correlation between the internal stress and phase difference DELTA of the sample, by which the internal strain of the work is relatively decided. A method for immersing the sample in HNO3 and treating the sample while oscillating the sample to prevent the generation of unequal etching is preferable as the method of precisely polishing the surface of this material to <=50Angstrom  surface roughness. The rate of etching is controllable by the concn. of the NHO3 and the etching time.
