Title: Resolver system position detector
Inventor: TANAKA TADASHI
IPC: G01D5/245
Filed: 1985-02-14
Abstract: PURPOSE:To perform high-precision position detection by converting the detec tion signal of a resolver which has a number P of couples of magnetic poles into a two-phase signal which has 2<n>.P (n: positive integer) cycles per rotation of an thetam of rotation. CONSTITUTION:Pulse train signals E2a and E2b are outputted from a phase- locked loop circuit 20 corresponding to the position detection signal e0 of the resolver/whose number of magnetic pole couples is P and those signals are converted into two-phase sine-wave signals e21 and e22 of frequency 2<2n>.(f+ or -DELTAf) through the 2nd signal converting circuit 40. Pulse train signals E1a and E1b from an exciting circuit 10, on the other hand, are converted into two-phase wave signals e11 and e12 of frequency 2<n>.f through the 1st signal converting circuit 30. Then, an arithmetic circuit 50 outputs two-phase signals Ex1 and Ey with an electric phase angle 2<n>.P.thetam which vary in angle thetam of rotation on the basis of the two-phase sine-wave signals e21 and e22, and e11 and e12. The position detection is performed on the basis of those two-phase signals to improve the detection precision of the resolver 1 whose number of magnetic pole couples is P by 2<n> times.

Title: Induction motor type canned motor pump
Inventor: KONISHI YOSHIAKI
IPC: H02K17/02
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To form a stator can without using welding by integrally forming a stator iron core by being sealed in synthetic resin made by hardening reactive original liquid by an insulating stator mold part covering the side surface and both the end faces of the stator in core and the can. SOLUTION: A stator molding part 34 and a can 1 are integrally formed by polycyclopentadiene. The outer peripheral part of the can 1 is penetrated into teeth part that a stator iron core 31 has. Therefore, the can 1 does not separate from the stator mold part 34 or the stator iron core 31, although a stator 3 remarkably generates heat, while this induction motor type canned motor pump is used. Because polycyclopentadiene has strength and stretch which is close to metal and becomes further tough when heat is added, the thickness of the can 1 becomes sufficient in strength even at the tipmost of the teeth part of the stator iron core. Thus, the stator can be formed without welding and can be inexpensively manufactured.

Title: Tracer control device
Inventor: MATSUURA HITOSHI
IPC: B23Q33/00
Filed: 1992-02-13
Abstract: PURPOSE:To smoothly machine a corner area at a decreased speed without stopping the movement of a tool even if biting of a tracer head occurs. CONSTITUTION:A tracer speed command value VX is obtained by tracer- computing the displacement detected in a tracer head and input to a FIFO memory 1. The FIFO memory 1 normally stores tracer speed command values VX in the order of inputting by only a designated number of delay and outputs the first input data at a point of time when the storage capacity overflows. The memory has a cutter deceleration processing function of decelerating the movement of a cutter at a point of time when biting occurs at the tracer head. When biting occurs at the tracer head, the output position coordinates corresponding to the reduction ratio integrated value are determined from the plural position data stored in the FIFO memory 1 and output to each shaft motor 36 on cutter side. Sequentially, an increment from the preceding output position is calculated to determine a command value corresponding to a reduction ratio integrated value.
