Abstract: PURPOSE:To gradually change the inclination ange of a vane so as to highly efficiently produce an impeller at low cost by moving a side milling machine in a direction orthogonal to a rotary shaft to cut a vane and turning the side milling machine by a turning shaft orthogonal to the rotary shaft. CONSTITUTION:A turning shaft 5 capable of moving forward and backward is provided on the feed table 2 of a feed base 1 having a linearly moving mechanism and its one end is connected to a motor 7 through a reduction gear 6. To the other end of the turning shaft 5, is orthogonally attached a cutter base 8.

Title: Controller for electric automobile
Inventor: MARUMOTO KATSUJI
IPC: H02P7/06
Filed: 1982-02-12
Abstract: PURPOSE:To improve the accelerating performance at the accelerating time by applying correction of an armature current which decreases in response to the variation in the rotating speed of an engine at the current instruction value at the accelerating time. CONSTITUTION:An armature current instruction generator 10 outputs a current instruction Imc in response to an acceleration signal ACC, and a DELTANm detecting and instructing correction value calculator 12 outputs a correcting instruction value ImD=DELTANmXKN (DELTANm: variation in the motor speed, KN: correcting gain). An adder 122 adds the current instruction ImC and the value ImD and calculates the corrected instruction value ImO. A butting circuit 84 calculates the deviation between the value ImO and the signal Imff which is averaged value of armature currents imf, and applies a current flow rate alpham through a compensator 81 and a current flow rate control oscillator 82. In this manner, the accelerating performance can be improved at the accelerating time without defecting the stability of a current control system.

Title: Glass tube bulb
Inventor: INUKAI SHINJI
IPC: H01J61/36
Filed: 1989-01-31
Abstract: PURPOSE:To prevent deformation or movement of an introduced conductor during sealing by thinning the central part of a sealing area gradually from the thickest part to the thinnest parts on both ends under a predetermined condition. CONSTITUTION:A sealing 2 with which an introduced conductor 3 is sealed airtightly is thinned gradually from the thickest central part 8 to the thinnest parts 9 on both ends, for which a relational expression regarding the thickness of the thickest part 8 (a), the thickness of the thinnest part 9 (b), and a distance between the thickest part 8 and the thinnest part 9 d is defined as 0.035<=[(a-b)/2d]<=0.14. Since a molten glass thus receives the power directed to the thicker central part during a sealing process, a flow of the molten glass biased in both directions being suppressed, and also by the fact that it is getting thicker gradually from both sides to the center, the power is added to the molten glass in the central direction as a whole, and consequently it is possible to prevent leaning or movement of a piece of metal foil 4. In this way, deformation or movement of an introduced conductor can be prevented.
