Title: Disk cartridge
Inventor: KANAZAWA YASUNORI
IPC: G11B23/033
Filed: 1984-05-26
Abstract: PURPOSE:To suppress the formation of cutting scraps of a cartridge case due to a shutter slide by providing projection parts for reinforcement in parallel to the side edge part of a shutter provided slidably to the cartridge case. CONSTITUTION:The U-shaped shutter 12 is provided slidably to right and left outside the cartridge case 10 and opens and closes a spindle hole 10c and a head insertion hole 10d simultaneously. Projections 12c and 12d for reinforcement provided projecting along both side edge parts 12b of the shutter 12 slide on flat parts 10g and 10b of the case. The shutter 12 is therefore reinforced to have superior strength and durability, and the side edge part 12b never interferes with the case 10 directly and produces no cutting scrap, so there is no deterioration in the performance of the disk due to the sticking of cutting scraps and the gap is sealed with the projections 12c and 12d, preventing foreign matter from entering it.

Title: Bloch line memory device and information erasing method
Inventor: MARUYAMA YOJI
IPC: G11C11/14
Filed: 1989-04-27
Abstract: PURPOSE:To shorten the time required for erasing information by moving a Block line to a groove pattern or a non-magnetic area such as an in-plane magnetizing layer or an instable area in a state that a stripe magnetic domain is coupled to such an area. CONSTITUTION:A stripe magnetic domain 1 is closed near a groove pattern 6 for erasing, which is formed by digging a groove in a ferromagnetic substance film 16. Afterwards, when a ferromagnetic field is impressed between one part of the closed stripe domain 1 and one part of the groove pattern 6 for erasing in a direction equal to the magnetizing direction of the stripe magnetic domain 1, the stripe magnetic domain 1 is enlarged towards the groove pattern 6 for erasing and coupled with the groove pattern soon. In such a way, one part of Bloch magnetic domain walls is set in a state to be coupled with the area, where a Block line is made instable at least, or with the nonmagnetic area and the Bloch line is moved to this area. Thus, since it is not necessary to successively execute it concerning all the Bloch lines that the Bloch line is transferred, cut off afterwards and erased like conventional operation, the time required for erasing the information can be widely shortened.

Title: Apparatus for measuring free chlorine in sample water
Inventor: NISHIKATA SATOSHI
IPC: G01N31/00
Filed: 1989-04-26
Abstract: PURPOSE:To measure free chlorine by transferring free chlorine in sample water to a gaseous phase while preventing the condensation of moisture on the inner wall of a measuring apparatus by mounting a gaseous phase extraction means, a carrier gas humidity conditioning means and a semiconductor type detection means. CONSTITUTION:Free chlorine in sample water is transferred to carrier gas by a gaseous phase extraction means 15 and the humidity of the carrier gas containing chlorine subjected to gaseous phase extraction is conditioned by a humidity conditioning means 16. A semiconductor type detection means 17 detects the amount of free chlorine transmitted to the carrier gas. Both of free chlorine and bound chlorine are transferred to the carrier gas by the gaseous phase extraction means 15 but the semiconductor type detection means 17 responds only to free chlorine and only hypochlorous acid in the sample water can be separated and measured without receiving the effect of bound chlorine in the sample water. Further, since the steam pressure in the carrier gas is held to saturated steam pressure or less by the humidity conditioning means 16, no moisture is condensed on the inner wall of a measuring apparatus and the re-dissolution and re-emission of free chlorine are eliminated and free chlorine in the sample water can be measured with high accuracy.
