Title: Hysteresis brake
Inventor: KOBAYASHI YOSHIYUKI
IPC: H02K49/04
Filed: 2003-03-10
Abstract: <P>PROBLEM TO BE SOLVED: To accomplish the manufacture of a hysteresis brake at low cost and reduction of its shaft length.  <P>SOLUTION: A hysteresis material 28 to be fixed on a shaft member 27 is formed in a disk shape. First and second yokes 23 and 24 are disposed on both sides of the hysteresis material 28 in the axial direction. A plurality of pole teeth 23a and 24a extending in the radial direction are formed on the faces of the first and second yokes 23 and 24 facing the hysteresis member 28 in the circumferential direction. The pole teeth 23a and 24a of both the yokes 23 and 24 are offset in the circumferential direction. Coil windings 29 which produce magnetic fields are disposed on the circumferential side of both the pole teeth 23a and 24a. While the hysteresis material 28 is in disk shape, the pole tooth formation faces of the yokes 23 and 24 facing thereto are flat. Therefore, the hysteresis material 28 and the yokes 23 and 24 can be formed with ease. Further, since the coil windings 29 are disposed on the circumferential side of the pole teeth 23a and 24a, the shaft length is shortened.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To achieve a good, stable piezoelectric characteristic and to provide many nozzles in high density by making each piezoelectric element be in a shape whereby the piezoelectric elements can be arranged in high density.  <P>SOLUTION: Each of piezoelectric activating sections 42 is made to be in a shape whereby they can be arranged in high density and in a matrix fashion. That is, the many nozzles 10 can be arranged in high density. As the piezoelectric activating section 42 is so constituted that an aspect ratio of a driving section which is in roughly the same shape of a pressurizing chamber is approximately one and a connection section 42D with an electric pad section is constricted, it allows the driving section to be readily deformed by a piezoelectric function. As a result, it is possible to obtain a high driving efficiency per unit area and the good, stable piezoelectric characteristic. The shape of each of the piezoelectric activating sections 42 permits the piezoelectric activating sections 42 to be arranged in high density and in the matrix fashion and to have the good, stable piezoelectric characteristic. Therefore, it is possible to provide an inkjet recording head and an inkjet recorder capable of performing forming of a good, stable image at a high speed.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
