Title: Permanent magnet member and manufacturing method thereof
Inventor: YAMASHITA KEITARO
IPC: H01F41/02
Filed: 1993-06-08
Abstract: PURPOSE:To manufacture the title permanent magnet member having excellent magnetic characteristics and the freedom in the selection of magnetizing pattern at low cost by a method wherein the shafts in smaller diameter than that of middle part are formed on both ends of the cylindrical body as a ferrite base sintered magnet material while plural magnetic poles extending in the axial direction are provided on the outer peripheral surface of the middle part. CONSTITUTION:When a sintered body 23 is held on a wear plate so as to restrain the movement thereof in the axial direction for low speed turning an adjusting wheel 22, the sintered body 23 is turned at the same peripheral speed as that of the adjusting wheel 22. Next, when grinding stones 21 are high speed turned to horizontally shift (cutting movement) the axis of the adjusting wheel 22, both ends of the sintered body 23 are ground by the grinding stones 21 to form the shanks 23a, 23b. Through these procedures, the title permanent magnetic member can be formed into a substantially solid cross cylindrical body thereby enabling the magnetic characteristics thereof to be improved by the volume effect. Furthermore, due to the individual machining of the shaft and the elimination of complicated bonding operation, the permanent magnet member can be manufactured at low cost.

Abstract: PURPOSE:To enable writing of a mark for registering at relative position that conforms to the pattern without lowering the processing capacity of a photo- composing machine and enable accurate registering by forming a registering mark on a print for automatic registering in a printing machine. CONSTITUTION:To print a pattern, an original plate 3 of the pattern is set to a printing frame 2, and a print plate P is set to the table of machine stand. Then, a punch card indicating the position of printing is inserted. The printing frmae 2 of a head moves according to the position indicated by the card, and the patternes are printed successively. When the printing frame 2 moves for printing next pattern, if a registering mark forming device 4 passes near the position where the registering mark is to be written, the registering mark is written during the movement at the position indicated by the punch card. That is, when the registering mark forming device 4 comes on the writing position, an electromagentic solenoid 7 operates and lowers a marking-off pin 6 and brings its tip into contact with the print plate P. A chevron-shaped registering mark (m) is formed by movement of a head 1.

Abstract: PURPOSE:To let reflected wave intensities be proportional to the shape of objects by making at least one beam out of ultrasonic transmission and reception waves to a narrow beam width. CONSTITUTION:The ultrasonic beam 6 of a wide width from a transmitter 4 refrects on an object 20 and is received as reflected beams of a narrow width in the respective elements 51, 52 ... of a receiver 5.

Title: Visual inspection method and device
Inventor: MATSUZUKA NOBUKADO
IPC: A61B5/16
Filed: 1995-05-12
Abstract: PURPOSE: To accurately measure the break of light (boundary value) by keeping the light emitting status of a light source dimmed or shaded at a constant period, and gradually shortening dimming or shading time during the period with a lapse of time from the start of inspection. CONSTITUTION: A power supply is turned on and the switch 9 of an operation section 5 is operated. As a result, a dimming time control section 4 operates to cause a light source 2 to emit an inspection beam of discontinuous light having a constant period and a change only in dimming time. Also, the inspection beam is controlled so as to gradually become shorter with a lapse of time from an inspection start, and finally become continuous without any dimming time. A testee keeps his/her eye in contact with the opening 6 of a cylindrical case 1, and visually observes a light source 2. At the start of the inspection, the inspection beam looks discontinuous light, but is finally recognized as continuous light.  In this case, when the switch 9 is operated, a dimming time value at the time of switch operation is shown on a dimming time display section 3, thereby a self-diagnosis such as an extent of fatigue to be made for a visual system is made possible.
