Title: Bonding method for pellet
Inventor: YAMAMOTO EIJI
IPC: H01L21/58
Filed: 1980-11-21
Abstract: PURPOSE:To prevent the generation of voids on the interface of a pellet with a glass layer by using a glass layer having a projection in the central part thereof for bonding the pellet. CONSTITUTION:The low-melting glass layer 2 having a projection 2a in the direction of thickness is formed in the central part on a ceramic base 1 where the pellet is to be bonded. After the glass layer 2 is softened, pellet bonding is conducted by pressing the pellet 3 on the glass layer 2. According to this method, the glass layer 2 contacts with the central part of the pellet 3 first at the projection part 2a and later expands in wet to the periphery of the pellet sequentially. At this time, air on the lower surface of the pellet is extruded to the outer-peripheral part of the pellet 3 and finally driven out from the side edge thereof. Thus, no voids remain between the lower surface of the pellet 3 and the glass layer 2 and a structure with pellet having high bonding strength of the pellet and excellent heat-radiation characteristic is obtained.

Title: Measurement of quantity of heparin
Inventor: SHIMIZU YOSHIHIRO
IPC: G01N33/66
Filed: 1998-06-11
Abstract: PROBLEM TO BE SOLVED: To determine heparin in suspension by binding a colouring matter to heparin of a polymer body on the surface or inside of which heparin is bonded, dipping the same into the suspension, and measuring the absorbance of the suspension in which the colouring matter is eluted. SOLUTION: A tube bonded with heparin is manufactured, and a colouring matter is bonded to heparin bonded to a polymer body by, for example, dipping the polymer body on the surface or inside of which heparin is bonded, into the liquid in which the colouring matter is dissolved, by ionic bond. Then the polymer body is dipped in the suspension such as a solution of salt or the like to be bonded to the heparin and to be freely eluted. The absorbance of the suspension in which the colouring matter is eluted is measured, and the amount of heparin in the suspension is determined on the basis of the measured absorbance. As the measured absorbance of the suspension is corresponded to the amount of heparin bonded to the polymer body corresponding to the amount of freely eluted colouring matter, the amount of heparin bonded to the polymer body can be measured by measuring the absorbance of the suspension. That is, the amount of heparin can be indirectly measured by utilizing the colouring matter.

Title: Low-noise preamplifier for magnetic resistance data transducer
Inventor: PATTI GUISEPPE
IPC: G01R33/09
Filed: 1998-06-11
Abstract: PROBLEM TO BE SOLVED: To supply a small amount of current from a high load resistance to obtain a large gain at a first stage thereby reducing a noise by supplying a constant amount of current from a pair of current sources to a first stage of a preamplifier to obtain a current sufficient for reducing a bias current applied via an MR readout head so as to disappear. SOLUTION: A preamplifier 50 supplies from first and second current sources 80 and 82 a constant amount of current which is sufficient for reducing a bias current to be applied via an MR readout head 60 (RH) so as to disappear. As a result, a relatively small amount of current is supplied from a load resistance 56 thereby allowing a resistance value RL of the load resistance 56 to increase. Accordingly, it is possible to obtain a relatively large gain at a first amplifying stage 52 composed of the load resistance 56, an NPN bipolar transistor 58 and the MR readout head 60. Thus, noise contribution of the load resistance 56 is reduced and noise contribution of a second amplifying stage 54 can also be significantly reduced.
