IPC: G11B7/09
Filed: 1984-12-04
Abstract: PURPOSE:To stabilize the motion of an object lens holder in a track direction remarkably by providing the object lens holder with a magnetic body which holds the neutral position by a magnetic force. CONSTITUTION:A magnetic circuit 21 is fixed to a floor board 20, and the coil part of an object lens holder 12 is arranged in the gap part of the magnetic circuit 21, and the magnet 22 of the magnetic circuit 21 is magnetized in a thickness direction. A small iron piece 23 is placed in the center of a track coil 14 and in the object lens holder 12. when an electric current is flowed to the track coil 14, a driving force is generated in the track direction by a magnetic flux generated by the magnetic circuit 21, and the driving force is transmitted to the object lens holder 12, and it is rotated and moved back and moved back and forth with a shaft 17 as the center. A force which pulls back the object lens holder 12 to the center is generated by the attraction between the small iron piece 23 provided in the gap of the magnetic circuit 21 and the magnet 22, and this force acts as the neutral position holding force.

Title: Thin film magnetic head
Inventor: NANAUMI SACHIKO
IPC: G11B5/31
Filed: 1987-10-14
Abstract: PURPOSE:To extend a service life and to increase head output by setting a signal coil side ridge on the core connecting plane of a gap part which regulates track width so that a part conforming to the track center can be protruded higher than the part conforming to a track end part. CONSTITUTION:In a core connecting part A, a projecting part 7 is formed in such a way that the ridge of a signal coil 4 side is formed in a projecting shape so that the part conforming to the track center can be protruded higher than the part conforming to a track edge part on a plane side being abutted with a recording medium, and loss recessed parts 8, 8 are formed at both sides of the projecting part 7. Consequently, at the part where the corner of a pattern is rounded, gap depth Gd is positioned at the signal coil side nearer than a position of 0, and no change occurs in the track width to the 0 position of the gap depth Gd. In such a way, the service life of a magnetic head can be extended until it wears to the position of the gap depth Gd, thereby, it is possible to realize the long service life of the magnetic head. Also, the head output can be increased since initial gap depth can be reduced when the head with the same service life is used.

Title: Analyzer having automatically dispensing function
Inventor: TAKEDA MASAAKI
IPC: G01N35/10
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To prevent splashing of a delivered residual liquid while improving a treating speed in the replacing of a nozzle chip of the analyzer for having an automatically dispensing function. SOLUTION: A pressure sensor 70 is provided to measure a pressure in a nozzle base part 52 into which is press-fitted a nozzle chip 54. A control part 80 controls the operation of pulling the nozzle chip 54 out of the nozzle base part 52, based on a pressure value to be outputted from the pressure sensor 70. The control part 80 detects that the pressure value begins to lower and switches the pulling out operation from a high speed to a low speed, which can prevent a sharp drop in the pressure within the nozzle chip 54 to block the fouling of the nozzle base part 52 as caused by the splashing of a delivered residual liquid. When detecting that the pressure value reaches an atmospheric pressure, the control part 80 judges that there is no risk of splashing to accelerate the pulling out operation.  This allows a low speed operation only during a period when the risk of splashing remains possible and a high speed operation during the other periods thereby shortening the treating time.
