Filed: 1988-08-31
Abstract: PURPOSE:To aim at ensuring machining a workpiece with a high degree of machining accuracy and at lowering the cost by providing a forming surface corresponding to a dynamic pressure generating groove, in a machining ceramic material which does not react with a ceramic material to be machined under a processing condition and has a melting point higher than that of the ceramic material to be machined by 200 deg.C, and then by performing a hot-press. CONSTITUTION:With the use of a ceramic material which has a melting point higher than that of a ceramic material to be machined made of materials such as Al2O2 or a material containing as a main component the latter, and which does not react with the ceramic material to be machined under a processing condition of the ceramic material to be machined, the ceramic material to be machined is formed into a dynam ic pressure bearing plate 10. Further, a forming surface corresponding to a dynamic pressure generating groove 13 is provided in the machining ceramic material, and thereafter the ceramic material to be machined is subjected to a hot press.

Title: Thermal recording head
Inventor: ZEN MUNETOSHI
IPC: B41J2/345
Filed: 1986-09-19
Abstract: PURPOSE:To enable a printer to be easily attached and to attain miniaturization thereof and high density attachment by a method wherein a heating function part and a drive circuit system are connected by forming a wiring pattern with laser cutting after printing of all the surface of metals. CONSTITUTION:A heating function part 2 is arranged on the edge face of a substrate 3, and a drive circuit system 4 containing a driving 1C 5 is arranged on the flat face of another substrate. The functional part 2 and the drive circuit system 4 are connected by forming a wiring pattern by cutting with a laser after effecting printing or plating of gold all over the surface. Since a drive circuit wiring 11 and a common wiring 10 can have enough wiring width as compared with that for the heating part, and also, they have an enough wiring interval, cutting with the laser do no cause trouble. Since a direct motion area is comparatively small in such a side face-type thermal recording head, a cassette for transfer film can be made also smaller and is easily mounted on a printer or the like. It can be miniaturized and the high density attachment can be achieved.

Title: Determining method for composition of oxide single crystal
Inventor: MIYAZAWA YASUTO
IPC: G01N21/31
Filed: 1994-09-14
Abstract: PURPOSE: To enable quantitatively determining the composition of single crystals easily in a short time without fabricating a test piece by quantitatively determining the composition of Tbx M1-x AlO3 single crystals from the wavelength of an optical absorption edge obtained from an absorption spectrum of the single crystals which is measured by use of an ultraviolet light source and a spectroscope. CONSTITUTION: When a transmission spectrum is measured as to Tbx M10x AlO3 single crystals (M: the elements in Group IIIA of the periodic table such as Gd, (x): a composition value, 0.5<=(x)<=1.0) grown with various compositions, the wavelength of an optical absorption edge shows a linear relationship with the composition of the crystals, i.e., (x) value when 0.5<=(x)<=1.0. The (x) value is calculated by least square approximation using an equation: (x)=-(Eopt -250.0)/9.6 [Eopt : the wavelength (nm) of the optical absorption edge]. Quantitative determination of the crystal composition can thus be made experimentally from the wavelength of the optical absorption edge by the use of the equation, and the optical characteristics of the oxide single crystals can be evaluated.
