IPC: E21B4/14
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To obtain an efficient excavation method by forming discharging window holes in a casing in vertical and radial directions at suitable intervals, and discharging excavated muck together with air blown from a down-the-hole hammer drill. SOLUTION: A drill shaft is connected to an output shaft 4a of a motor, and a down-the-hole hammer drill 5 which reciprocates by compressed air is attached to the front end of the drill shaft. The compressed air is supplied through the interior of the drill shaft, and a casing 2 hung down from the rotary driving section 4 encloses the drill shaft. The casing 2 has discharging window holes 10 formed therein vertically and radially at suitable intervals. An excavator main body is moved on a guide 11, and carries out excavation by drilling rock mass by means of a head 5a. Excavated muck is blown up through the interior of the casing 2 together with air discharged from the head 5a, and a large portion of the air and the excavated muck is discharged from the window holes 10 in close proximity to the ground surface. Thus, efficient and stable excavation can be achieved.

Title: Camera for photograph and method of determining film speed
Inventor: DANIERU MAIKERU PAGANO
IPC: G03B7/24
Filed: 1992-04-02
Abstract: PURPOSE: To provide a photographic camera capable of detecting a film speed. CONSTITUTION: The camera 201 is used with a film cassette 1 equipped with a film speed indicator. The film speed indicator is made movable between a housing position and a using position. The detection is not received by the indicator at the housing position, but, the detection is received by the indicator at the using position. The film cassette with the indicator lying at the housing position is stored in a loading chamber 205 of the camera. When the film cassette is inserted into the loading chamber, the indicator is moved by a cam pin 209 from the housing position to the using position. Whether the indicator lies at the using position, or the housing position is detected by a detecting member 223, then, the speed of the film in the film cassette is decided.

Title: Sheet transfer mechanism
Inventor: OTSUKI SHINICHIRO
IPC: B65H5/06
Filed: 1985-04-18
Abstract: PURPOSE:To enable an user to easily correct the oblique movement of a sheet by making the width of a sheet transfer roller smaller than that of a separating roller to reduce a force rotating the obliquely supplied sheet in the oblique moving direction. CONSTITUTION:When a sheet 1 is obliquely supplied, it contacts the widthwise end p of a transfer roller 6. When the sheet 1 begins to be transferred by the roller 6, a force PP=(PB-PA)sintheta tending to rotate the sheet 1 reduces <O2O1p=theta, assuming that the center of the roller 6 is O2, since the distance lbetween the center O1 of a separating roller 4 and the widthwise end p of the roller 6 is short. Thus, sintheta is lessened and the force PR tending to rotate the sheet 1 becomes extremely small, so that it is offset against friction on each point of contact surfaces. Also since the distance l is short compared with prior one, the sheet 1 supplied under the oblique transfer condition can be corrected with few possibility of folding the sheet 1.

Title: Bone measurement method
Inventor: MORIMOTO KENJI
IPC: A61B6/03
Filed: 1996-04-03
Abstract: PROBLEM TO BE SOLVED: To evaluate the structure of bone strength more accurately and quickly, by measuring side length cut by an arbitrary large number of lines in binary digit image information made by extracting only a bone part of an interesting section to obtain a statistical index. SOLUTION: A section image of an interesting part of a subject bone photographed by μX-ray CT is inputted into an image processor to be converted to binary digits by the discrimination analysis method. Then the primary moment of a bone part section around the Y axis is calculated to obtain the center of gravity G. The binary digit image is rotated so that the inertial main axis passes the coordinates of the center of gravity to be parallel with the Y axis. A straight line L to cross the sponge bone part passing a reference point P arbitrarily decided is set and the product of the image including only the straight line L and the binary digit image is calculated. That is, k points of bone trabecula section sides tcl are extracted. The reference point P is moved a statically sufficient number of times, for instance 100 times, to reset the straight line L a statically sufficient number of m times. Bone marrow section side length obtained those times is measured to obtain the bone marrow section side length of the arrangement result of mcl[l][m][k].

Title: Toner for developing electrostatic charge image
Inventor: KUMAGAI YUUGO
IPC: G03G9/08
Filed: 1984-04-23
Abstract: PURPOSE:To obtain a toner which obviates offset in fixing with hot press rolls and obviates sticking of printed pattern to non-rigid PVC by incorporating a vinyl polymer in which the glass transition point of the polymer having >=50,000 mol.wt. is specific  deg.C and the ratio of the polymer is specific weight % into said toner. CONSTITUTION:The vinyl polymer has a hydroxyl group in such a way that the hydroxyl value attains 50-350, more preferably 80-250(KOHmg/g). Sticking to non-rigid PVC cannot be prevented if the hydroxyl value is <50 and the deteriorated electrifiability of the toner is resulted from increased hygroscopicity if said value exceeds 350. The glass transision temp. of the polymer having >=50,000mol.wt. among the vinyl polymers is 20-90 deg.C, more particularly preferably 30-80 deg.C. The blocking resistance of the toner is inferior if <20 deg.C and fixability is inferior if said point exceeds 90 deg.C. The ratio of the polymer with the vinyl polymer is 5-95wt%, more particularly 10-90wt%. The effect of improving offset is not expected at <5wt% and the fixability of the toner is inferior if the ratio exceeds 95wt%.

Then the frequency is best selected with respect to a reception signal independently of the difference from the characteristic of the tuning sections 23, 25.
