Title: Production of magnetic head
Inventor: OTA HIROYUKI
IPC: G11B5/187
Filed: 1989-11-17
Abstract: PURPOSE:To form a track groove free of a dummy part by a single cut by reciprocating a grinding disk with the thickness of the grinding part made smaller than the specified width of the track groove in the direction orthogonal to a head core block and the grinding direction and simultaneously rotating the disk. CONSTITUTION:A track groove is formed on a head core block 62 by a working device 60. The block 62 is obliquely arranged on the upper surface of a table 61 to be moved in the grinding direction A at an angle corresponding to the azimuth angle and bonded. Meanwhile, a blade 64 as the grinding disk is rotated integrally with a spindle 63. The thickness E of the grinding part of the blade 64 is made smaller than the specified width F0 of the completed track groove, and the table 61 is reciprocated in the direction B orthogonal to the direction A with minute amplitude. Accordingly, the blade 64 is reciprocated by a minute dimension (a) in the left and right directions with respect to the block 62, hence the effective blade width F0 is obtained, and a track groove 25 having a specified width F0 is formed.

Inventor: IIIZUMI MASAHIKO
IPC: B24B33/06
Filed: 1994-12-02
Abstract: PURPOSE: To correctly discriminate a machined hole diameter by always maintaining the temperature of a workpiece provided with a machined hole and the temperature of a master ring provided with a reference hole for inserting a honing head, almost equal so as to reduce an error caused by the thermal expansion difference. CONSTITUTION: A honing head 1 is fitted into the machined hole H of a workpiece W, and a head body 3 is rotated and elevated so as to perform honing to the machined hole H by honing sticks 7. In this case, the temperature of a master ring 27 provided with a reference hole 27H into which a spindle 21 connected to the head body 3 is inserted, and the temperature of the workpiece W are always kept almost equal. The temperature of the master ring 27 at the time of detecting a reference clearance dimension between the honing head 1 and the reference hole 27H, and the temperature of the workpiece W at the time of detecting a clearance dimension between the honing head 1 and the machined hole H are also kept almost equal.  An error caused by the thermal expansion difference between the master ring 27 and the workpiece W is thereby reduced so as to be able to correctly discriminate the diameter of the machined hole H.

Filed: 1986-12-16
Abstract: PURPOSE:To detect the presence and place of the gap between a molding resin and a lead wire by a method wherein a semiconductive device is immersed in a fluorescent aqueous solution and subsequently drawn up to wash off the solution and the solution remaining in the gap is irradiated with ultraviolet rays to investigate the presence of the generation of fluorescence. CONSTITUTION:A semiconductive device 1 is packed by a molding resin 3 so as to expose a part of the lead wire 2 thereof. This device is immersed in a fluorescent aqueous solution for a predetermined time and subsequently drawn up and a liquid 6 composed only of the solvent remaining after removing a fluorescent indicator from the solution 5 is sprayed to the device 1 in a mist form to wash off the solution adhered to the surface of the device 1. Next, the liquid 6 is sprayed to the exposed part of the lead wire 2 so as to be adhered thereto. Whereupon, in the lead wire 2 having a gap 4 between the molding resin 3 and the lead wire 2, the solution 5 remaining in the gap 4 is mutually diffused along with the liquid 6 to exude in the direction of the lead wire 2. When the lead wire 2 is irradiated with ultraviolet rays 8, green fluorescence 9 is emitted from the solution 5. Therefore, by observing the fluorescence 9, the presence of the gap 4 and the lead wire 2 having said gap 4 can be identified.

Title: Remote measuring system for optical repeater
Inventor: WATANABE AKIRA
IPC: H04B10/035
Filed: 1991-11-18
Abstract: PURPOSE:To measure the degree of allowance and to make the high quality measurement and maintenance by performing a signal folding test in the transmission line according to the density of positive and negative CMI violation and the set value in the inversion period. CONSTITUTION:In the optical repeater, a detection circuit 14 detects the presence or absence of the CMI violation of the reception signal to be sent for a period monitoring circuit 15. The circuit 15 measures the inversion period of the positive and negative CMI violation, and when matched with the set period sending a folding control signal to a holding circuit 12. The circuit 12 receives the folding control signal and changes the output destination of the reception signal inputted from an optical reception circuit 11 to be made opposite to the transmission direction at its output to an optical reception circuit 13. Because the higher the density of CMI violation becomes the higher the low-frequency component becomes, it is hard to discriminate between '1' and '0' of the signal. Thus, the density of the CMI violation density is changed to measure the range of identification, measuring the degree of allowance of the reception.
