Title: Thin film magnetic disk
Inventor: YONEKAWA TAKAO
IPC: G11B5/738
Filed: 1985-10-23
Abstract: PURPOSE:To obtain sufficient strength of the titled disk for the sliding and contact with a magnetic head by forming a protective film consisting essentially of Si and C on the surface of the thin film magnetic disk. CONSTITUTION:A substrate layer 2 of an Ni-P alloy and a magnetic medium 3 are formed on a substrate 1 obtained by grinding an Al-Mg alloy substrate, and the material is preheated at 200 deg.C in vacuum. After the material is kept under such conditions for several hours, a sintered SiC target is RF-sputtered in an Ar atmosphere to form an SiC film 4 on the magnetic medium 3. Consequently, when the magnetic head and the magnetic disk rotating at high speed are accidentally brought into contact with each other, or the head slides on the disk by a CSS, the strength sufficient to resist the contact is provided, and the deformation and chipping of the protective film itself resulting in head crash can be prevented.

Inventor: TANAKA ATSUSHI
IPC: G06F3/03
Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To provide a coordinate input device and method which can suppress the fetching of errors. SOLUTION: A vibrator drive circuit 2 drives a vibrator 4 by the instruction of an arithmetic control circuit 1, and the vibrator 4 produces the vibrations of two different frequency (f0, f1). These vibration are inputted via a contact secured between a vibration pen 3 and a vibration transmission plate 8 and reach the vibration sensors 6a to 6d via the plate 8. Thus the vibrations are detected by the sensors 6a to 6d. A signal waveform detection circuit 9 notifies the circuit 1 of the arrival timing of vibrations of both frequency f0 and f1, and the circuit 1 calculates the transmission distance from the transmission time of every vibration. When the coincidence is confirmed between these two detected distances, no fetching of a wavelength error is decided.  These operations are carried out for each of sensors 6a to 6d for calculation of the distance between the input position of vibration and every sensor. Then the coordinate value are calculated from these calculated distances, respectively.

Abstract: PROBLEM TO BE SOLVED: To enable effective manufacture, developement of natural woodgrain patterns, and reduce uneven color tone or the like as compared with the case of applying paint to a sliced veneer by laminating a colored semitransparent film to the sliced veneer through dry operation. SOLUTION: Semitransparent film 13, which is composed of colored synthetic resin and has no pacifying properties, is laminated, using an adhesive 12, to a sliced veneer 2, which is formed by cutting natural wood into thin sheets. The sliced veneer 2, on which the semitransparent film 13 is laminated, is adhered to a base 1 surface such as plywood or the like through an adhesive 3 for manufacturing woody building material. Woody color such as brown or the like is preferable for the semitransparent film 13. By laminating the colored semitransparent film 13 on the sliced veneer 2, appearance color is developed by the color of the semitransparent film 13, which imparts color to the pattern of the sliced veneer 2. Thereby, color change problem caused by absorbing of the coloring paint into the sliced veneer 2 and the base 1 is resolved, and unevenness of the color is reduced.

Abstract: PURPOSE:To realize an electrode with excellent heat-withstanding, low-resistance features by a method wherein a metal to easily react with Si is deposited on an Si layer and then is coated by a heat-withstanding metal before silification. CONSTITUTION:Pt is the first metal 28 to be deposited on the entire surface of a substrate 21. Mo is the second metal 29 to be further deposited on the first metal 28. Heat treatment results in the formation of a metal silicide electrode 30 on an N<+> diffused layer 27 and gate electrode 24. That is, the first metal 28, second metal 29 on the N<+> layer 27 are converted into metal silicides. Similarly, the first metal 28, second metal 29 on the gate electrode 24 are converted into metal silicides. On the other hand, the first metal 28, second metal 29 on a relatively thick SiO2 layer 22 and side wall 25 are converted not into silicides but into a mixture layer 31 including Pt and Mo. Only the mixture layer 31 is removed in the next process, whereafter metal silicides can be formed by self- alignment on the exposed Si.
