Title: Information processor
Inventor: SANBE HIDEO
IPC: G06F3/06
Filed: 1989-11-24
Abstract: PURPOSE:To always confirm the current remaining size of a disk by displaying the information on the present remaining capacity of the disk loaded in a disk driver in a state where an information processor is started. CONSTITUTION:When an information processor is started, an information processor main body 1 reads the remaining size of a disk loaded in a disk driver 3. Then the main body 1 compares the read remaining size with the threshold value set previously and decides either one of three prescribed levels with which the remaining size of the disk is identical. Then a remaining size display device 4 displays the disk remaining size in three levels, i.e., 'satisfactory', 'rather unsatisfactory' and 'unsatisfactory' via the blue, yellow and red LEDs respectively. Thus the present remaining size information on the disk loaded in a disk driver 3 is always displayed with the information processor started. Then an operator can always confirm the current remaining size of the disk with no labor nor time required for input of commands. As a result, the operability of the information processor is improved.

Title: Dielectric film and device thereof
Inventor: YOSHIDA KAZUO
IPC: H01L21/822
Filed: 1992-11-13
Abstract: PURPOSE:To provide a dielectric film which has a great dielectric quantity per unit area and whose insulation resistance is not deteriorated by heat treatments by adding other specific dielectric additives to an amorphous Ta2O5 dielectric film of high dielectric constant. CONSTITUTION:To form a dielectric film using resistance heating vapor deposition method and from amorphous Ta2O5 with a great dielectric constant, the amorphous composition is converted into a polycrystal structure by subsequent heat treatments carried out at temperatures of 660 deg.C and higher and then its electric resistance value is reduced and consequently the functions of the dielectric film are deteriorated, so at least one kind or more of dielectric material such as SiO2, Al2O3, Si3N4 and AlN is added to the Ta2O5 in a ratio of 2 to 50mol%. Addition of those materials prevents polycrystallization of the amorphous Ta2O5 during the heat treatments, so the Ta2O5 dielectric film with a great dielectric constant and a device using it can be manufactured without causing an increase in leak current due to lowering of the resistance value resulting from polycrystallization.

Title: Magnetic disk drive
Inventor: KASAGI YASUHIDE
IPC: G11B5/09
Filed: 1990-11-13
Abstract: PURPOSE:To obtain a magnetic disk drive with high reliability by writing into a write/read circuit in a gap domain with a write current which attenuates from the value at the write time to the minimum value necessary to record data. CONSTITUTION:When a write request signal 8 from a host computer is 'L', a diode 31 is turned ON and the potential at a point A becomes 0. Consequently, a transistor TR 30 is turned ON, and a resistor 28 for setting a write current value and a resistor 29 for setting the minimum current value are connected in parallel between a terminal 32 and a positive direct current source terminal VCC, whereby a write current control signal 17 represents saturation current. When the write request signal 8 from the host computer is terminated and becomes 'H', the diode 31 is turned OFF, with the potential at, the point A raised because of the discharging characteristic of a capacitor 26 and a resistor 27. Accordingly, the write current control signal 17 is decreased, the TR 30 is turned OFF, and only the resistor 29 is connected between the terminal 32 and the source terminal VCC. Therefore, the current control signal 17 becomes minimum. Thus, the write current is turned to 0.

IPC: E21D11/14
Filed: 1998-10-26
Abstract: PROBLEM TO BE SOLVED: To retain the strength of a lining structure regardless of the inside water pressure acting in a shield tunnel by providing a water retaining layer made of a porous material at the outer surface of segments and forming water holes connecting the water retaining layer and the inside face of the segment through the through holes. SOLUTION: A water retaining layer 20b made of a porous material is provided at the external surface of ordinary segment bodies 20a and water holes 20c are formed to connect the water retaining layer 20b and the inside face of segments facing the inside space of a tunnel through the water through holes. In this way, spring water out of the natural ground 11 of the tunnel and pressurized water in the shield tunnel can mutually flow through the holes while appropriately stagnating in the porous material in the water retaining layer 20b. The pressure difference brought between the underground water pressure and the inside water pressure of the shield tunnel is canceled out to reduce a stress acting on the tunnel structure such as the segments or the like. Further, both economical efficiency and workability can be remarkably improved by this relatively simple structure.
