Title: Focus detecting device
Inventor: AKASHI AKIRA
IPC: G03B13/36
Filed: 1989-11-10
Abstract: PURPOSE:To perform smooth focus adjusting operation by initializing a selected area and performing new selecting operation when the focal length of a photographic lens varies exceeding a specific quantity. CONSTITUTION:An MSK is a visual field mask, an FLDL is a field lens, and a DP is a stop. Then AFLs are secondary image forming lenses consisting of four couples of eight lenses and arranged behind the stop DP corresponding to respective openings of the stop DP and SNSs are sensors consisting of four couples of eight sensor arrays and arranged corresponding to the secondary image forming lenses AFLs so as to photodetect their images. The focus detecting device inhibits new selecting operation from being performed when a subject area (sensor) in the center of a picture plane is selected and a detecting means 102 inputs the focal length (f) of the photographic lens 101 to discriminate whether the difference from last focal length information exceeds the specific quantity, and release the inhibiting operation of an inhibiting means 104 when the specific quantity is exceeded to perform new selecting operation. Consequently, the smooth focus adjusting operation is performed.

Title: Method and device for measuring shape dimension of workpiece
Inventor: YOSHIDA JUN
IPC: G01B21/00
Filed: 1997-10-23
Abstract: PROBLEM TO BE SOLVED: To measure shape dimension of a workpiece highly accurately by employing a measuring probe for a measuring head which presents its pressing stroke different in the measuring direction installed on a main spindle. SOLUTION: Pressing strokes corresponding to normal lines of a measuring probe 11 for a measuring head 10 which is installed on a main spindle 9, are obtained in the form of a pressing stroke data table through a calibration means such as a calibration sphere of a known radius R. Then, the measuring probe 11 is moved from a measuring start point along the normal lines so that it approaches plural measuring target points P of a workpiece W to detect a three-dimensional coordinate value at each target point, and further, the pressing strokes PL in the normal line direction at the time of measuring are calculated from the plural pressing strokes PLn which are selected from the pressing stroke data table, and by compensating the detected three-dimensional coordinate values at the measuring target points P with those pressing strokes PL,  highly accurate measurement of the shape dimension of the workpiece W is achieved.

Title: Bearing
Inventor: SAKAGUCHI NORIHISA
IPC: F16C23/04
Filed: 1991-11-07
Abstract: PURPOSE:To support a rotating shaft so as to rotate smoothly by excellently coping with center deviation even if this deviation is generated between the rotating shaft and amounting hole where a bearing is installed through the rotating shaft. CONSTITUTION:A radial sliding bearing 1 as a bearing is constituted of a floating bearing 4 provided with a shaft part 4b of outer diameter phi1 which directly journals a rotating bearing 2 so as to rotate freely, and a fixed bearing 3 where the shaft part 4b of the floating bearing 4 is fitted loosely, and which has a mounting hole 8 whose inner diameter phi2 is formed larger that the outer diameter phi1, and is installed at the installation hole 20 of a supporting plate 21. Therefore, a clearance (d1+d2) exists between the mounting hole 8 of the fixed bearing 3 and the shaft part 4b of the floating bearing 4, so the clearance compensates center deviation even if this deviation is generated between the rotating shaft 2 and the mounting hole 20. It is thus possible to journal the rotating shaft 2 to the floating bearing 4 so as to rotate smoothly.

Title: Production of highly reactive coke
Inventor: YAMAGUCHI KAZUYOSHI
IPC: C10B57/06
Filed: 1992-10-29
Abstract: PURPOSE:To produce a highly reactive coke which is strong enough to maintain air flowability in a blast furnace, has no problem relating to the life and operation stability of the furnace, and exhibits a very small dispersion of JIS reactivity. CONSTITUTION:The amt. of an iron compd. added to coal is determined depending on the value of JIS reactivity of coke which is obtd. without adding the compd., the type of the compd., and the increase in JIS reactivity per unit amt. of Fe in the compd. added. The compd. in such an amt. is added to coal, which is converted into coke under the same conditions as when the compd. is not added. Adding the compd. improves the gasification rate and reactivity of the resulting coke without accelerating damage to or deposition on wall bricks of a blast furnace and without decreasing coke strengths. Thus, coke is produced which exhibits a very small dispersion of JIS reactivity while having no problem relating to the life, air flowability, and stable operation of the furnace.

Abstract: PURPOSE:To make it possible to collect dust at high efficiency and put a filter in an electrically charged space to make a device smaller by disposing a wave- shaped dust collecting filter in zigzag manner between positive and negative electrodes, both of them having protrusions thereon, which are alternately parallelly arranged. CONSTITUTION:When a fan 15 is driven by a motor 16, an air stream 7 is formed, so that the indoor air is sucked through suction ports 11a into a box 1 to be passed through positive electrode plates 12b and protrusions 12c of a positive electrode 12, a dust collecting filter 14 and negative electrode plates 13b of a negative electrode 13 and is delivered into the room from outlet ports 11b, while DC high voltage is applied between the positive electrode 12 and negative electrode 13, so that corona discharge takes place from the protrusions 12c of the plate 12b, whereby particles of dust passing therethrough are electrically charged. Since, at the same time, an electric field is set up between both the electrode plates, the particles of dust are collected on the filter 14 at high collection efficiency. In this manner, the filter 14 is housed utilizing a space between both electrode plates 12b,13b, making thereby the device smaller.

Abstract: PROBLEM TO BE SOLVED: To perform collation print the number of copies not less than a total number of discharge bins. SOLUTION: When a first copy is printed (S41, S42), print image data are stored (S43). After the first copy is completely printed (S44: YES), it is checked whether a specified number of copies is completely printed or not (S46). If the specified number of copies is not completely printed, one or more copies are printed one by one with changing a paper-discharging place until the number of copies is completely printed (S47-S50). Accordingly, the respective usable discharge bins are repeatedly and circularly used until the number of copies reaches to the specified number of copies. A discharge bin having no reservation of other users or a discharge bin wherein printed papers are not discharged to a paper discharging upper limit value is detected as the usable discharge bin so as to be circularly used.
