Title: Antiwear protective film for thermal head
Inventor: NAGAO KUNIHIRO
IPC: H01C7/00
Filed: 1985-10-16
Abstract: PURPOSE:To provide a thermal head enhanced in hardness and hardly generating a crack due to recrystallization and having excellent acid/alkali resistance, by providing the antiwear protective film for the thermal head based on Si, Al, O, N and M (wherein M is a rare earth element and especially at least one element selected from Y, La, Ce, Gd, Nd, Sm and Er). CONSTITUTION:An antiwear protective film for a thermal head is composed of an Si-Al-O-N-M type substance. Herein, M is at least one rare earth element pref. at least one element selected from Y, La, Ce, Gd, Dy, Yb, Nd, Sm and Er. More pref., said protective film is constituted of a substance represented by SiAlaObNcMd (wherein a=0.05-0.5, b=0.05-0.5, c=1.0-2.0 and d=0.01-0.2). If Al is too little, the fragility of the film increases and, if too much, heat conductivity increases and printing sharpness is reduced. O and N have the function of increasing the hardness of the film but, if they are too little, the film becomes flexible and, if too much, the film becomes porous and fragile. M enhances resistance against scratch and increases cracking resistance. Various characteristics are satisfied in a range imparted to a, b, c, d.

Title: Hetero-crystal structure
Inventor: SUZUKI TORU
IPC: H01L21/20
Filed: 1985-10-15
Abstract: PURPOSE:To enable a P-type ZnSe crystal to grow on a GaAs substrate by providing a AlAs crystal or Al0.5In0.5P crystal between the ZnSe crystal and the GaAs crystal so as to be in contact with the two, thereby preventing the diffusion of Ga. CONSTITUTION:On a GaAs substrate 1, AlAs2 or a Al0.5In0.5P crystal is laminated several hundreds A to several thousands A as a crystal for barrier. A ZnSe crystal 3 is grown thereon, and at this time As or P or N is introduced as a P-type dopant. Due to the structure obtained in this way, the ZnSe crystal 3 exhibits a low-resistance P-type conductivity. This is because entering from the GaAs crystal to the ZnSe crystal is prevented by the AlAs which is the crystal for barrier. Since the ZnSe is allowed to have complete lattice matching with the GaAs at a room temperature by introducing about 6% of S to change the ZnSe to ZnS0.06Se0.94, a hetero structure may be naturally considered in which the ZnSe is replaced by ZnSxSe1-x(x=0.06).

IPC: A61K35/14
Filed: 1982-12-25
Abstract: PURPOSE:To separate surely and quickly the serum in a blood from blood cells and fibrin by using an auxiliary means. CONSTITUTION:When an auxiliary means 1 is subjected to a preliminary centrifugal sepn. or is allowed to rest for 30-60min after a blood 10 is put therein, fibrin F and blood cells C begin to deposit and therefore the means 1 is turned upside down at the point of that time and is subjected to the normal centrifugal sepn. When the auxiliary means is turned upside down in such a way, the separating member 5 and the blood cells C deposited in the lower part are positioned conversely in the upper part and since centrifugal force is applied thereon, the member and cells move toward the lower part of the means 1. The serum S of small specific gravity which is separated from the cells C by receiving the effect of the centrifugal force and is going to move to the upper part of the tube 2 moves upward by passing freely through the aperture of the member 5 but the aperture of the member 5 prohibits the passage of the fibrin F and therefore the fibrin F is moved, in the state of having weight of the member 5 and the cells C, toward the lower part of the means 1 and the serum S is distinctly separated from the others.
