Title: Pick feed device for machine tool
Inventor: SATO YASUHIKO
IPC: B23Q5/32
Filed: 1988-03-30
Abstract: PURPOSE:To perform a desired pick feed motion only through control of an exciting current and to enable execution of a grinding work under an optimum pick feed, by providing an exciting control means which is adapted to control the exciting current of a magnetic bearing so that the rotor shaft is forward and backward moved in the direction of the rotor shaft in the magnetic bearing. CONSTITUTION:In coarse grinding feed, a pick feed amount responding to the coarse grinding is set. Along with the starting of a pick feed, a lamp signal is fed from a control part 15 to a computing circuit 17 through a D/A converter 19. The exciting currents of electromagnets 6a and 6b on both sides in a thrust magnetic bearing 6 are controlled so that after a rotor shaft 2 is moved backward to a target position through amplifiers 18a and 18b by a control circuit 18, it is returned to its original reference position. Similarly, in a fine grinding feed work, a given pick feed action is also performed.

Filed: 1991-03-18
Abstract: PURPOSE:To make it possible to perform highly accurate exposure by correcting the intensity of synchrotron radiation which is applied to a mask for X-ray lighography based on the distribution of the film thickness of the mask for X-ray lithography. CONSTITUTION:Synchrotron radiation 11 which is emitted from a light emitting source 10 is expanded into a size large enough for its application to an exposure region with a fixed convex mirror and is applied to an X-ray transmitting film 16 of an X-ray mask 14. The X-ray mask 14 is arranged so that the changing direction of the distribution of the thickness of the X-ray transmitting film 16 agrees with the changing direction of the intensity distribution of the synchrotron radiation 11. A shutter 13 wherein an opening part 19 is formed is moved in the above described changing direction with respect to the exposure region. The moving speed is changed in response to the changes in the intensity of the synchrotron radiation 11 and the thickness of the X-ray transmitting film 16. In this way, the illuminating time for the exposure region with the syncrotron radiation 11 is changed.

Title: Method for absorbing waving of steel strip in hot rolling
Inventor: TABEI KUNIO
IPC: B21C47/32
Filed: 1984-04-17
Abstract: PURPOSE:To improve winding of the front end of a steel strip on a coiler by pulling the front end of the steel strip on a pass table at a high speed to eliminate the waving thereof and exerting back tension thereto if the waving cannot be thoroughly absorbed. CONSTITUTION:A waving detector 12 calculates tracking length and calculates at the same time the waving quantity at the front end of the steel strip 1 when the mill bite signal M2 from a bite detector 11 and the revolving number signal M1 from an encoder 10 are inputted thereto and further when the detection signal K1 for the front end of the steel strip from a detector 5 is inputted thereto. If the waving quantity is larger than a reference value, a command signal R2 for absorbing the waving is outputted from the detector 12 and is inputted to a speed controller 16 for a rear table which increases the conveying speed of a rear pass table 8, thereby absorbing the waving. The front end of the strip 1 is further detected by a detector 6 just prior to winding on a coiler 4 and the signal thereof is inputted to a waving detector 15 which calculates the waving quantity and compares the same with a reference value. The back tension is exerted to the front end of the strip 1 to absorb the waving by decreasing sharply the speed of the table 8 when said value is larger than the reference value.

Title: Single layer self-color developing pressure-sensitive recording paper
Inventor: TOYAMA KOUJI
IPC: B41M5/128
Filed: 1978-06-26
Abstract: PURPOSE: To ensure an extremely high printing color developing capacity preventing the breakage of the capsule due to external pressure by adding polyolefin- affiliated powder to a coating liquid.  
     CONSTITUTION: Polyolefin-affiliated powder mainly composed of polyethylene perferably ranges from 10 to 30 micron in the average grain size. The powder additives yield a capsule protective effect particularly at 100 to 200% in the amount with respect to microcapsule, while producing a single layer type self-color developing pressure-sensitive recording paper with an ample printing concentration. The total amount of the polyolefin powder and the starch grain to be added exceeds 150 part by weight with respect to the total microcapsule of 100 part by weight. In short, the application of the polyolefin-affiliated podwer can elevate the printing color-developing capacity to an extremely high level performing a protective function against the external pressure sufficiently.

Title: Feed and return apparatus for feed bar in press
Inventor: ARAI TOSHIHIKO
IPC: B21D43/05
Filed: 1989-03-28
Abstract: PURPOSE:To reduce an approach operation speed and to prevent a work from missing clamping by providing a lever rocking in the feed and return direction of a feedbar round the center part of rocking by a drive force transmitted from a crankshaft and deviating this central part of rocking to the return side. CONSTITUTION:When the center part 19 of rocking of a lever 16 is deviated to the return side, the locus of the end part of a side connecting a lever 16 with a feedbar 4 is made so asymmetric that the return side rises remarkably. The return operation of the feedbar 4 ends early and the feed operation begins lately, consequently, these operating times are lengthened. When a setting angle and position of an eccentric member to the crankshaft 1 are shifted to such a side that the time for beginning the feed and return of the feedbar 4 is delayed, the timing of operation for the feed and return lag. When the return operation is delayed until the conventional time, the feed operation is begun further lately and since the approach operation of the feed bar 4 is desired to be finished before the feed operation begins, the approach operation can be prolonged and further decelerated.

Title: Dish washer/drier
Inventor: SUZUKI HAJIME
IPC: A47L15/46
Filed: 1991-04-10
Abstract: PURPOSE:To prevent the reduction of the washing performance by using the larger permeability between the permeability before the action of a water feeding means and the permeability after the completion of the action as a reference. CONSTITUTION:Permeability is detected by a permeability detecting means 33 before the washing water is fed into a cavity 1 by a water feeding means. The permeability at this time is normally the largest. Permeability is again detected after the water feed. The permeability at this time is normally smaller than the permeability before the water feed for the washing water, and the permeability is made further smaller as the concentration of the filthiness of the washing water near a permeability detection section is made larger due to the residual juice in dishes stored in the cavity 1. A controller compares the permeability before the water feed and the permeability after the water feed and uses the larger one as a reference. The controller controls the washing, rinsing and drying sequences thereafter.
