Title: Disk control system
Inventor: KINO TORU
IPC: G06F12/00
Filed: 1990-06-07
Abstract: PURPOSE:To enable a user to control a large capacity file covering plural disk volumes with high efficiency by performing a file access after regarding a control file as a real file and retransferring automatically these files due to the overvolume. CONSTITUTION:A user regards a control file A' stored in a control file 12Aa as a real file A and has an access to a disk. The file A' stores the No (n) of a disk volume stored in the file A and therefore an OS 11a included in a CPU 11 has an access to a real file included in a volume (n) to return the writing result of the real data and the read data to the user as the results. Meanwhile the user can use an access interface to a normal file with no consciousness of the presence of a control file. Thus the user can control a large capacity file covering plural disk volumes with high efficiency.

Abstract: PURPOSE:To prevent the damage to the silicon surface and the exfoliation of a gate electrode due to ion implantation by a method wherein the part in which ions will be implanted is oxidized or a silicon oxide film or other insulating film is deposited on the ion-implanting part before ions are implanted. CONSTITUTION:A silicon oxide film 15 is formed by oxidizing the silicon surface of the region 16, which becomes a source and drain, before impurities are ion- implanted for the purpose of forming a source electrode and a drain electrode on both sides of a gate electrode 15 using the gate electrode 13 as a mask. The upper part of polycrystalline silicon 13 is oxidized by the above-mentioned oxidizing process, and a silicon oxide film 14 is formed. As a result, the damage generating on the silicon surface is prevented by the silicon oxide film 15 when an ion-implanting operation, in which the source and drain region 16 is formed is conducted. At the same time, the impurities ion-implanted are prevented by the silicon oxide film 14 from reaching a channel region 17 passing through the polycrystalline silicon.

Abstract: PURPOSE:To prevent elements in an inverter from being damaged due to a large current by opening the contact of a relay circuit when the output value of a current detector exceeds a predetermined value. CONSTITUTION:The output signal of potentiometer 21 is input as a slip frequency omegas to an adder 70 to be added to the output omegar of an F/V converter 69, and the adder outputs a synchronous rotation frequency omega1. The frequency omega1 is converted to quantized sinusoidal waves of four types having a frequency corresponding to the value of the frequency omega1, and output as a synchronous rotation frequency omega1. The waves omega1 are converted to quantized 3-phase primary current commands of four types having a frequency corresponding to the value of the frequency omega1, and further converted to an analog 3-phase primary current command. When an accelerator pedal is released, an analog switch 71 is closed to supply the output omegar of the converter 69 as a subtracting element to an adder/subtractor 72 to regeneratively operate it. On the other hand, when the output voltage of a CT 76 in a shortcircuit protecting unit 73 becomes a set value or higher, the contact of the relay circuit 74 is opened.

Title: Dropout compensation system
Inventor: USUI SHIYUUJI
IPC: H04N9/88
Filed: 1978-12-06
Abstract: PURPOSE: To compensate a dropout with high precision by applying a picture signal of the strongest correlation to a dropout position in reproduction, by storing picture signals and a dropout signal in a picture memory for one frame and dropout memory.  
     CONSTITUTION: Reproduced RF signal 1 is inputted to dropout detector 2 and demodulator 3. When signal 1 is below a level set value, detector 2 outputs dropout signal 4. Demodulator 3 demodulates signal 1 into picture signal 5. Since this signal 5 has variation in time axis, its time axis is stabilized by time-axis corrector 6 and the signal is sequentially stored in one-frame memory 7. On the other hand, signal 4 is so corrected by time-axis corrector 8 that its time axis will be in phase with signal 5, and it is sequentially stored in one-frame memory 9. Therefore, memory 9 is stored with dropout information of signal 5 stored in memory 7 at the same addresses.

Filed: 1986-06-26
Abstract: PURPOSE:To stably inject an ink droplet, by mounting a bypass on the outer wall of an ink pressurizing chamber and arranging a second piezoelectric vibrator driven in synchronous relation to a piezoelectric vibrator with phase shift to the outer wall of the bypass apart form said piezoelectric vibrator. CONSTITUTION:When a piezoelectric vibrator 8 returns to an initial state, the volume of an ink pressurizing chamber 3 increases to generate negative pressure and this negative pressure passes through an orifice 4 and ink is sucked from a tank part 5. At the same time, said negative pressure is also transmitted to a nozzle part 2 and a meniscus is retracted to be ready to draw in air. In order to prevent this phenomenon, a bypass 6 having a connection part 7 is provided on the side of the pressurizing chamber 3 from the nozzle part 2 and, when the cross-sectional area of the connection part 7 is too large, positive pressure for injecting an ink droplet escapes to the bypass and, contrarily, when too small, no bypass effect is expected. Then, a second piezoelectric vibrator 9 is added apart from the piezoelectric vibrator 8 to be adhered to the outer wall of the bypass 6 and driven in synchronous relation to the piezoelectric vibrator 8 and a phase is shifted so that the piezoelectric vibrator 9 begins to slacken immediately before the piezoelectric vibrator 8 returns to an initial state from a bent state.
