Title: Impurity concentration measuring device
Inventor: YOSHIDA HARUHIKO
IPC: H01L21/66
Filed: 1990-03-26
Abstract: PURPOSE:To enable the impurity concentration to be non-destructively measured rapidly and easily by a method wherein the intensity and the attenuation hours of the fluorescence emitted from a direct transition type compound semiconductor are measured when said semiconductor is irradiated with pulse laser beams. CONSTITUTION:The fluorescence emitted from a specimen 2 by laser beam irradiation is focussed by lenses 5 to enter a photo-detector 7 through a filter 6. Since the pulse laser beams are cut off by the filter 6, the fluorescence only is detected by the photo-detector 7. Within a data processor 8, the intensity of fluorescence IPL and the attenuation hours tauPL can be measured by the detecting output from the photo-detector 7. Furthermore, the ratio of tauPL/IPL is measured according to the measured data while the multiple carrier concentration p can be measured in terms of the relation between said multiple carrier concentration p and said ratio tauPL/IPL. That is, the impurity concentration of the specimen 2 can be measured.

IPC: B29C33/44
Filed: 1992-02-28
Abstract: PURPOSE:To enhance productivity by shortening the taking-out time of an injection molded product and preventing not only the deformation of the molded product at the time of taking-out but also the breakage of the ejection pin of a mold ejecting the molded product. CONSTITUTION:In a method for taking out an injection molded product, the chuck surfaces of a taking-out unit are arranged in parallel to the surfaces (a), (b) to be chucked of a molded product 1 and the taking-out unit is advanced to the gap between molds 2, 2a in the direction parallel to the surfaces to be chucked and allowed to protrude so as to eject the molded product from the molds before the taking-out unit advances to the gap between the molds or at the almost same time when said unit advances to said gap. Thereafter, the chuck surfaces of the taking-out unit grasp the molded product to pull out the same from the molds and, thereafter, the taking-out unit is retracted from the gap between the molds.

Title: Equal velocity universal joint
Inventor: IWASAKI KEIJI
IPC: F16D3/20
Filed: 1986-04-02
Abstract: PURPOSE:To reduce the frictional force for causing a vibration, in a triport type equal velocity universal joint, by inserting a second shaft having three foot shafts mounting a spherical roller into the inner face of an outer ring, then contacting the roller guide face of a track groove made in the outer ring and a roller at two points. CONSTITUTION:Three track grooves 12 are made axially in the inner circumferential face of an outer ring 10 with an interval of 120 deg.. Each track groove 12 is provided at the opposite sides with a roller guide face 13 having two radii of curvature. A triport member 15 to be inserted into the outer ring 10 has three foot shafts 20 and a spherical roller 21 is fixed rotatably. Said spherical roller 21 does not contact against the central portion and the opposite ends of the roller guide face 13 but contacts conventionally against the opposite ends of the spherical roller 21, thereby it is not removed from the roller guide face 13 by its contact stress to cause an edge load nor to increase the frictional resisting force.

IPC: B29C39/40
Filed: 1979-06-15
Abstract: PURPOSE:To prevent the surface of a building panel from being marked due to the steps of a lower mold caterpillar, by winding a soft belt around the lower mold caterpillar which is for producing the foamed layer of the building panel and by winding a steel belt around the soft belt. CONSTITUTION:An upper and a lower mold caterpillars 3, 4 are provided in face of each other. A soft belt 5 and a steel belt 6 are wound between the lateral frame lugs 8 of the lower mold caterpillar 4. A mold separating belt 11 is wound around the upper mold caterpillar 3.

The panel is prevented by the steel belt 6 from being marked due to the steps of the lower mold caterpillar 4. Since the soft belt 5 is provided, the thickness of the steel belt 6 can be reduced and the diameter of drums 7 can be therefore decreased.

Title: Image forming device
Inventor: NAKATOMI KICHIJI
IPC: G03G15/01
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To easily house a unit in a fixed position without any error by constituting an image forming device so that each image forming unit permits the housing operation of an adjacently housed unit, when it is a predetermined one, and inhibits the housing operation, when the adjacently housed unit is not the predetermined one. SOLUTION: Except when the respective image forming units 11B, 11C, 11M and 11Y are correctly housed in the fixed positions of a frame 31 corresponding to the units 11B, 11C, 11M and 11Y by engaging projections B11... provided in the units 11B, 11C, 11M and 11Y, any of them can not be housed in the frame 31. For instance, when an operator tries to erroneously house the unit 11Y in a position except a correct position, the unit 11Y can not be housed because the engaging projection Y12 interferes with the engaging projection C22 of the adjacent unit 11C. In other words, it is constituted so that the units 11Y, 11M, 11C and 11Bk permit the housing operation, when the adjacently housed unit is the predetermined one and inhibit the housing operation, when the adjacently housed unit is not the predetermined one.

Title: Field-weakening controller
Inventor: SUGIMOTO SHUNICHIRO
IPC: H02P7/298
Filed: 1985-04-12
Abstract: PURPOSE:To prevent a hunting in a field-weakening control by detecting a current after the prescribed delay time from the closing or opening operation of a field-weakening contact. CONSTITUTION:An operational amplifier OP2 outputs a signal H when an armature current is at the first set value I1 or lower and a signal L when at the second set value I2 or higher. A bypass circuit 14 turns On a transistor TR2 when an accelerator is fully opened to excite the exciting coil 13 of a full-open contactor. An operational amplifier OP1 outputs a signal H when the circuit 14 operates and the output of the amplifier OP2 is H to excite the exciting coil 12 of a field-weakening contactor 12. At this time, a monostable multivibrator IC2 locks the amplifier OP2 for the prescribed time at high level. In other words, the contactor 12 is held in closed state. Thus, it can prevent a hunting from occurring.

Title: Method of sidewise shift of paper sheet
Inventor: TAGUSARI KOUJI
IPC: B65H9/16
Filed: 1981-05-22
Abstract: PURPOSE:To allow a sheet to make sidewise shift without touching a positioning plate, by changing the relative speed between a pair of rollers for carrying the sheet held therebetween. CONSTITUTION:A left side drive roller 1 and a right side drive roller 2 are driven at the same speed in the first stage so that a sheet 5 is carried without slanting. In the second stage, since the right side drive roller 3 is driven at a speed higher than that of the left side drive roller 1, the sheet slants counterclockwise. In the third stage, the sheet 5 is carried while it is held in the slanted attitude, since the left and right side drive rollers 1, 3 are driven at the same speed. In the fourth stage, the left side drive roller 1 is faster than that of the right side drive roller 3 so that the sheet may turn clockwise. With the result,  the sheet 5 has been shifted to the right. In the next stage, the left and right drive rollers are driven at the same speed for carrying the sheet.

Filed: 1991-04-10
Abstract: PURPOSE:To prevent the wrong detection of defect in a semiconductor wafer or a printed board from occurring due to a pattern formation state difference between two patterns to compare in a comparison check method where a semiconductor wafer or a printed board is visually inspected. CONSTITUTION:Two patterns imaged through light field illumination are compared with each other and binarized and a logical product of a light field binary image signal b detected making a defect part 'H' level and a dark field painting image signal d which makes only a prescribed region 'H' level out of a dark field image signal c imaged through dark field illumination is obtained. An exclusive logical sum of the logical product signal e and the light field binary image signal b is obtained, whereby defects detected in a part other than a region where a pattern formation state difference occurs are judged true defects.
