Title: Method and apparatus for adjustment of seam length in cylindrical overlock sewing machine
Inventor: MARUYAMA TAKASHI
IPC: D05B27/22
Filed: 1987-11-10
Abstract: PURPOSE: To easily adjust the stitch length in a high efficiency, low cost and steplessly by providing a single eccentric component inside a cylinder at all the time, turning and adjusting that component from the outside of the cylinder. CONSTITUTION: Around the outer periphery of a feed adjust eccentric wheel 7, a notched part 37 is provided for inserting a push-button shaft top end 34a in order to adjust the stitch length. When a push-button 34 is lightly pressed, the push-button shaft top end 34a is abutted to the outer periphery of the feed adjust eccentric wheel 7 and when a pulley is turned while lightly pressing the push-button 34, the push-button shaft top end 34a is inserted between notched parts 37 and 37a of the feed adjust eccentric wheel 7 and a feed adjust plate 4. By strongly pushing in the push-button 34 once more, a feed adjust gear 1 and the feed adjust plate 4 are disengaged and the pulley is turned. Around the outer periphery of the pulley, a ruler is engraved and one stitch length is shown.  When the push-button 34 is detached after the desired stitch length is set to the matching mark of a belt cover, the stitch length can be adjusted as desired.

IPC: H01J29/76
Filed: 1986-12-01
Abstract: PURPOSE:To prevent the occurrence of overheating, by installing plural guide grooves in an inner surface of a trumpetlike deflecting yoke along the tube shaft of a CRT, and housing a saddlelike horizontal deflecting coil and a toroidal vertical deflecting coil in these grooves. CONSTITUTION:A deflecting yoke 1 has plural guide grooves 5 extending in the axial direction of a CRT, in the inner surface at regular intervals, and each interspace among them comes to a protuberance or a crest 6, so that a vertical deflecting coil 2 and a horizontal deflecting coil 4 are housed in these grooves 5. If the number of storage pieces of these vertical and horizontal deflecting coils 2 and 4 is allotted to these grooves 5 according to the design of each deflecting coil, a precision electromagnetic deflection is manufacturable in good repeatability. These vertical and horizontal deflecting coils 2 and 4 are not projected out of an inner surface of the deflecting yoke, and a magnetic field to be produced in these vertical and horizontal deflecting coils 2 and 4 when assembled can be directly entered in the protuberance 6. With this constitution, an eddy current is sharply reduced and, what is more, a dielectric loss and a copper loss both are reduced, thus a fear of overheating is eliminated.

Title: Magnetic fluid bearing
Inventor: HAYAKAWA MASAMICHI
IPC: G11B19/20
Filed: 1993-10-19
Abstract: PURPOSE:To obtain a stable dynamic pressure by forming a radial plain bearing of a non-magnetic material, and providing a larger annular magnet at its bore than a bore of the bearing. CONSTITUTION:A central stationary shaft 14 of this magnetic fluid bearing is formed of a magnetic material, radial plain bearings 15, 15 are formed of a non-magnetic material, and an annular magnet 40 is provided between the bearings 15 and 15. In this case, if the bearings 15, 15 are formed, for example, of a magnetic material, most of magnetic fluxes are concentrated at the bearing gap to form a cluster to cause adverse influence such as an increase in a starting torque. However, since the bearings 15, 15 are formed of the non-magnetic material, magnetic fluid is held not only by an inner periphery of the magnet 40 and the bearing gap but also in a bearing fluid retracted part thereby to obtain a stable dynamic pressure.

Title: Electronic clinical thermometer
Inventor: IKEDA MAKOTO
IPC: G01K7/42
Filed: 1990-10-24
Abstract: PURPOSE:To maintain the predicting accuracy against the change of the using conditions of a clinical thermometer by investigating the change with time of a predicted balanced temperature in a predetermined time with using the time when the changing rate with time of a measured temperature reaches a predetermined value as a reference. CONSTITUTION:An instrumentation circuit 11 obtains data from a temperature sensor part 51 in accordance with the control of a control part 8 for every minute time interval. A predicting part 3 reads the data in real time via a data load part 6, and an operation part 9 converts the data to a temperature. The temperature is stored in a memory 7. At the same time, the temperature is predicted and stored in the memory 7. Thereafter, when a judging part 10 detects that the changing rate with time of the detected temperature satisfies the sufficient conditions for prediction, the operation part 9 calculates the stability of the predicted temperature in a time prior to the detecting time of the judging part 10. The judging part 10 compares the stability with a predetermined reference value. As a result, if the predicted balanced temperature is stable, detection of the temperature is stopped. If the temperature is instable, the temperature is continuously detected.

IPC: G05B11/36
Filed: 1992-10-23
Abstract: PURPOSE:To attain the fixed position stop control with high accuracy by detecting easily the degree of magnetization of a spindle. CONSTITUTION:A magnetism generator 4 is attached to a spindle 3 of a motor 2 which is driven via an inverter 1.
