Patent JP-S6292216-A (JP)
Title: Production of magnetic head
Inventor: SHIMIZU NOBUO
IPC: G11B5/31
Filed: 1985-10-18
Abstract: PURPOSE:To facilitate the working of the minute pattern of the titled head by forming a recessed part having about the same shape and thickness as the lower magnetic layer at a position on the lower protective layer, forming the lower magnetic layer at the center of the recessed part and laminating an insulating layer and a conductor coil layer on the lower magnetic layer and the lower protective layer. CONSTITUTION:A pattern 3 for lift-off is formed on the substrate 1 of the magnetic head through the lower protective layer 2 as a mask. The recessed part having specified depth is formed on the protective layer 3 with reactive sputter etching by using the pattern 3 as the mask and using gaseous freon. Then a cobalt-zirconium-niobium alloy layer 4 is formed in specified thickness by sputtering, the alloy layer 4 is released by releasing the pattern 3 and the lower magnetic layer 5 is formed. Then a gap film layer 6 is formed and then the lower insulating layer 7 and the conductor coil layer 8 are formed on the lower magnetic layer 5. The upper insulating layer 9 and the upper magnetic layer 10 are further laminated thereon and the working of the magnetic pattern is facilitated.

Title: Head position controller
Inventor: NUKADA HIDEKI
IPC: G11B5/584
Filed: 1983-12-12
Abstract: PURPOSE:To absorb the meandering movement of a magnetic tape and to obtain a recording track having virtually no meandering deformation, by providing a means which holds the relative position between a head and a magnetic tape. CONSTITUTION:When a recording action is started, an operational amplifier 18 delivers a signal corresponding to the output signal variation of a photodetecting element 13, i.e., a signal corresponding to the position shift amount of a magnetic tape 3 from its prescribed position on a head 2 by the drive of a record mode tracking circuit 15. A servo circuit 19 and an amplifier 20 delivers a voice coil current to a voice coil 12 in order to delete the signal corresponding to the position shift amount of the tape 3. The coil 12 works in response to the voice coil current to shift a head holding part 11 in the width direction of the tape 3 and then to shift the head 2 in said width direction via a parallel plate spring 8. As a result, the relative positional relation is fixed between the head 2 and the tape 3 regardless of the meandering run of the tape 3. Thus the recording track of the tape 3 has virtually no meandering deformation.

Title: Water passing method in column row type underground continuous wall
Inventor: SAKAMOTO KEIICHI
IPC: E02D5/20
Filed: 1998-08-19
Abstract: PROBLEM TO BE SOLVED: To provide a water passing method which is extremely excellent in site efficiency by reducing the projection of a drain to an outer side of a cut-off wall as much as possible in a soil cement column row type underground continuous wall. SOLUTION: Soil cement columns 12 with a wide flange beam 11 are continuously installed underground to construct a cut-off wall 10. A drain 15 is arranged so as not to be excessively projected to a ground 13 on the outer side from the cut-off wall 10. An impervious steel plate 17 is installed in a closely fitting manner to the surface of an inner flange 16 of two the wide flange beams 11 to form a side wall on the side opposite to the ground of the drain 15. In the drain 15, a catchment side or a recharge side is opposite to a ground 13, and an underground water is shielded by the impervious steel plate 17 for the inner side.  Since most of the drains 15 are arranged within the wall thickness of the cut-off wall 10, and installed to the depth of an underground water- passing layer 19, the projection of the drain 15 to the outer ground 13 can be reduced, and the site efficiency is extremely excellent.

Title: Density adjusting method for electronic blackboard
Inventor: TAKAHASHI SHUJI
IPC: H04N1/04
Filed: 1986-09-30
Abstract: PURPOSE:To increase the density of a character or a graph written on a sheet without increasing the background density by providing a movable density adjusting device made of a raw material such as glass having a different refractive index from that of air. CONSTITUTION:The density adjusting device 7 is made of a raw material such as glass having a different refractive index from that of air and moved optionally by insertion.

Since described characters or lines in the focal state, however, thin or blur, if they are illegible, the density adjusting device 7 is inserted between the lens 4 and the sheet 1 to apply defocusing and to change the picture read width from the width LB to the LA thereby forming the relation of L2/LA>l2/l1. Thus, characters printed thin and blur are printed out as thick and easy to see characters.

Title: Trouble detection circuit and trouble diagnosis system
Inventor: IWASAKI KAZUHIKO
IPC: G01R31/28
Filed: 1984-11-07
Abstract: PURPOSE:To enhance the trouble detection probability of a logical circuit, by using inverse doubling MISR (Multiple Input Signature Register). CONSTITUTION:An inverse doubling MISR system consists of two MISRs 40, 41 (MISRG, MISRH) and the shift directions of MISRs are different. By the inverse doubling MISR system, it is shown that all of a single error and double errors can be detected. When the single error was generated (1), YG(x)=0 modG(x) and YH(x)=0, modH(x) are formed by the same reason as MISR and the detection of an error is performed [wherein e1(x) is an error pattern matrix]. When double errors were generated (2), YG(x) and YH(x) respectively contain two terms or zero term. Furthermore, because two elements ak1, ak2 do not simultaneously satisfy (condition 1) and (condition 2), at least one of syndromes YG(x), YH(x) comes to a non-zero polynomial expression and all double errors are detected. Double errors generated in detection patterns a0(x), a1(x),...am-1(x) from a circuit to be inspected can be detected at an 100%-level.
