Next, the excess part of the insulated layer is removed and while remaining insulated layers 151 and 152 on the upper face of the spacer 14, the shapes of upper faces 151a and 152a are curved. Afterwards, an upper magnetic core layer 16' and a protection layer 17 are attached and formed at the exposed part of the spacer 14 and the entire upper faces 151a and 152a. Then, the both sides of the layers 16' and 17 are removed to form a lower magnetic core 16, glass 18 is welded and set on the core 16, and a protection board 19 is joined. Thus, the generation of the pseudo signals is suppressed and the recording efficiency can be prevented from being lowered.

IPC: C12Q1/56
Filed: 1992-06-19
Abstract: PURPOSE: To realize bioassay of type 1-3 gold type Willebrand factor (VWF) by adding refined bothrocetin as well as refined ristocetin. CONSTITUTION: A refine bothrocetin is an essential element of bioassay for VWF disease and naturally extracted from the venom of rattlesnake in Brazil and refined or obtained through DNA rearrangement. The refine bothrocetin is supplied and brought into contact with the serum or plasma of a patient. VWF in the serum or plasma reacts on the bothrocetin to cause platelet aggregation. The extent of platelet aggregation indicates the presence of VWF in the serum or plasma quantitatively thus providing an index of VWF disease. The extent of platelet aggregation can be determined visually using an appropriate optical machine.  The bioassay specific to type 2 of VWF includes a process for bringing a part of the serum or plasma into contact with bothrocetin and then bringing another part thereof into contact with refined ristocetin before comparing the extent of platelet aggregation between them.
