Title: Deflection electromagnet
Inventor: MORII YASUJI
IPC: H01J37/147
Filed: 1991-03-13
Abstract: PURPOSE:To prevent gaps from being produced between thin iron sheets and reduce edge focus by disposing the thin iron sheets of the magnetic pole end surface portion of a deflection electromagnet so that the magnetic pole end surface of the deflection electromagnet is perpendicular to a beam locus. CONSTITUTION:After laminating thin iron sheets, tightly in parallel a cut is formed so that the magnetic pole end portion of the beam passage opening of a magnetic pole 13 is perpendicular to a beam locus. The cut may be formed either by being cut off by machining process after laminating similar sheets or by laminating the thin iron sheets after machining the sheets. With this constitution, since the thin iron sheets of short magnetic pole end surface can be also connected to a return yoke side 14, structural strength is attained. Because the thin iron sheets are tightly laminated, volumetric filling ratio of the magnetic body increases to eliminate adverse effect of eddy current and magnetic field characteristic is improved. Because the magnetic pole end surface is perpendicular to the beam, edge focusing is reduced and the need for compensating quadrupole component is eliminated.

Abstract: PURPOSE:To prevent a rotary sleeve from coming into contact with the internal peripheral surface of a center housing, by both allowing air to flow into an air bearing chamber and providing a balance groove in a prescribed position on the internal peripheral surface of the center housing. CONSTITUTION:If a rotary compressor is operated, a working chamber 43 in the delivery side becomes a high pressure pressing a rotary sleeve 30 to the delivery side. Then this pressing force, being changed by the position of a vane 16, causes the center of the rotary sleeve 30 to draw an oval pattern, and its peripheral surface tends to come into contact with the internal peripheral surface of a center housing 22 in a contact area in the delivery side. An air bearing chamber 40 is provided on the internal peripheral surface of the center housing 22, further balance grooves 9 are provided in left and right positions at an equal angle from a position P2 (or it may be possible in the position P2) symmetrical to a position P1 in which a maximum pressure is received. In this way, an air flow increased by air sucked from the balance groove 9 and a flow inlet 71 causes an air pressure to increase, and air bearing load power in the contact area of the air bearing chamber 40 is increased.

Title: Method of welding by welding robot
Inventor: TANAHASHI SAKAE
IPC: B23K9/095
Filed: 1984-03-13
Abstract: PURPOSE:To improve quality of multi-layer welding by storing follow up locus of the first layer welding in a memory and using this for control of a torch at the time of multi-layer welding. CONSTITUTION:In welding of the first layer, a torch 3 welds a weld line at rotation speed of a positioner 6 while weaving. During this welding, follow up locus of the torch 3 is stored successively in the memory in a robot control device 2. In welding of the second layer, the torch 3 is controlled by the position obtained by adding amount of shift l1, l2 to the memory of follow up locus of the torch 3 stored in the control device 2. As weld line follow up control is made by an arc sensor in welding of the first layer, follow up control becomes unnecessary in welding of the second layer. By this way in multi-layer welding, welding of good quality can be made without causing positional deviation between the torch and weld line.
