As a result, the transformation property of electrolytic solution increases ad then even a sectional part and a defective part can be repaired sufficiently. Moreover, addition of boric acid or borate and sugar-alcohol to an organic electrolytic solution allows the electrolytic solution to hold weak acidity and further, an oxide film to be maintained stably for a long time. As sugar alcohol, threitol, erythritol, arabitol, galactose, and allitol can be used.

Title: Magnetic disk device
Inventor: ISHIDA BUNJI
IPC: G11B21/21
Filed: 1989-11-02
Abstract: PURPOSE:To lower the impact force for which a magnetic head and a disk medium receive at the time of stop of start-up by providing a gas sensor and a gas cylinder so that the atmosphere of the inside of a head disk assembly can be held by air and gaseous fluorocarbon having prescribed partial pressure. CONSTITUTION:A head disk assembly HDA 1 has a magnetic head and a disk medium, and a gas generator 2 supplies gas from a gaseous fluorocarbon cylinder 3 containing gaseous fluorocarbon and an air cylinder containing compressed air 4, and controlled by a gas sensor 5. The inside of the HDA 1 is filled with gaseous fluorocarbon from the gaseous fluorocarbon cylinder 3 until it becomes prescribed partial pressure and a disk medium is rotated. When its speed of revolution becomes a stationary state, when the inside of the HDA 1 is set to a state that no gaseous fluorocarbon is present thereon, the floating quantity of the magnetic head falls and read/write can be executed. At the time of stop, it will suffice that the rotation of the disk medium is stopped by setting gaseous fluorocarbon to the prescribed partial pressure or below. In such a manner, impact force at the time when floating of the magnetic head is started and stopped is reduced.

IPC: A47B96/20
Filed: 1994-11-21
Abstract: PURPOSE: To obtain a decorative laminate which is good in yield and excellent in appearance of a surface and surface physical properties. CONSTITUTION: After gravure printing a grain patterned layer 2 on a colored polyvinyl chloride sheet 1, 1-2μm thickness radiation setting resin layer 4 is applied to a surface of the sheet 1. After making the resin layer 4 semihardened by irradiating the layer 4 with radiation (UV rays), the sheets 1-4 and a base material 5 having a curved surface are integrated, which is irradiated with radiation (electron rays). The radiation setting resin layer 4 is thoroughly hardened to make a decorative laminate. Since the radiation setting resin layer (a protective layer) 4 is unhardened in forming, link of molecular chains of the film surface is little. Even though the surface of the protective layer 4 is stretched, cracks are not generated. The surface follows deformation of the sheets 1-3 in forming.  Further, after thoroughly being hardened, the surface protective layer 4 which is excellent in scratch resistance can be formed.

Title: Pre-read control system
Inventor: MORIYOSHI SHUHEI
IPC: G06F3/06
Filed: 1988-11-14
Abstract: PURPOSE:To shorten the response time by deciding the interruption or the continuation of a pre-read process based on the identifying result of an access form when the switch of cylinders is required during a pre-read process. CONSTITUTION:An address information store means 121 stores the address information on the read commands received in sequence from a host. An access form identifying means 122 identifies whether the commands received from the host indicate the sequential accesses or random accesses. Then it is decided whether a seek instruction is produced or a pre-read process is interrupted when the switch of cylinders is required during the pre-read process. As a result, the response has no delay to a command even with a random access. While the data requested by the host is always limited to the data stored in a data buffer in the case of a sequential access. Then the response time is shortened to the commands together with improvement of the performance in a pre-read control system.

Abstract: PURPOSE:To measure the energy level of a semiconductor wafer in a non- contacting and nondestructive state at an ordinary temperature by measuring the lifetime variation of the minority carrier of the semiconductor wafer by forcibly changing the lifetime by changing the wavelength of bias light. CONSTITUTION:A wavelength setter 10 changes the wavelength of bias light from a bias light generator 9 so as to obtain the thermal equilibrium state corresponding to the wavelength. In addition, when an exciting light generator 4 starts/stops the emission of exciting light for irradiating a semiconductor wafer 2, the carrier concentration in the wafer 2 changes due to the generation/ reduction of excessive carriers and level variation occurs in the reflected wave of microwaves radiated 5 upon the wafer 2. The level variation is detected 7. The setter 10 forcibly changes the lifetime of the minority carrier of the wafer 2 by changing the wavelength of the bias light and a measurement circuit 11 measures the lifetime variation of the minority carrier in a thermal equilibrium state. The energy level of the wafer 2 is measured 11 basing on the wavelength of the bias light at the point at which the lifetime changes stepwise.

Title: Manufacture of touch panel
Inventor: MATSUDA MASAYUKI
IPC: G06F3/041
Filed: 1988-11-14
Abstract: PURPOSE:To obtain touch panels having regular intervals and high input accuracy, by using a flexible base material as at least either one of opposite insulating materials each having a film-shaped electrode formed on its surface, and laminating the flexible insulating material on the other while heating the former at temperatures lower than its softening point. CONSTITUTION:A flexible insulating base material 2, on which a film-shaped electrode is formed, is installed in a metal mold 1. Next, a fixed insulating base material 7 is installed in a metal mold 8 and the metal mold 1 is heated by means of a heater 4. A pipe 6 is then passed therethrough to absorb air from the surface of the metal mold 1 so that the base material 2 thermally expanded is stuck to the metal mold 1. Under these conditions, the metal molds 1, 8 are moved while in proximity to each other, so that the base materials 2, 7 are laminated on each other. The base 2 is therefore laminated thereon while being expanded, and does not contract when cooled down to room temperature, and thus touch panels having regular intervals and high input accuracy can be obtained.
