Abstract: PURPOSE:To enable an integrated circuit of this design to withstand a high voltage and be capable of a high speed operation by a method wherein a MES transistor, which has a large space between a gate electrode and a source (drain) region, is employed for a part where a high withstanding voltage is required and a MES transistor, which has a small space between a gate electrode and a source (drain) region, is utilized for a part where a high speed operation is needed. CONSTITUTION:The left section is a high speed MES transistor forming region S identical to a conventional high speed MES transistor and the right section is a high voltage MES transistor forming region V. An insulating film 4 is formed on the whole face of the high voltage MES transistor forming region which includes a gate electrode Gs through the conventional process. A space dV between a gate electrode and a source (drain) region of a high voltage MES transistor Iv is made to be larger than the ds of a high speed MES transistor Is. Therefore, the withstanding voltage between a gate and a drain of the high voltage MES transistor Iv is larger than that of a conventional one.

Filed: 1990-10-02
Abstract: PURPOSE:To simply recognize the useable state of a disk device after the active maintenance without an intervention of a main body device side by providing a first monitoring means for monitoring a useable state of the disk device and a second monitoring means for monitoring the disk device to be detached, etc. CONSTITUTION:A first monitoring means 6A monitors whether each disk device becomes a useable state or not, displays a disk device of a useable state on a first management register 4, and executes polling only to the disk device being not in a useable state. Subsequently, the disk device which becomes an object of detachment in the disk device to which a motor stop command is executed for the active maintenance is monitored by a second monitoring means 6B, and the disk device which becomes an object is displayed on a second management register 5. Next, by detecting a fact that the disk device is detached physically, the display of the register 5 and the display of the register 4 are changed to OFF and ON, respectively by a changing means 6C, and it becomes an object of polling. In such a way, a useable state of the disk device after the change at the time of active maintenance can be recognized simply without an intervention of a main body device.

Title: Treatment of alkali solution
Inventor: OTANI AKIRA
IPC: C02F1/461
Filed: 1987-10-20
Abstract: PURPOSE:To lower the pH of an alkali soln. and the concn. of ions in the soln. by electrochemically oxidizing hydroxyl ions with a first electrode and capturing cations with a second electrode. CONSTITUTION:Hydroxyl ions in an alkali soln. are electrochemically oxidized with a first electrode of Ni, Pt, etc., to generate gaseous oxygen. A p-type electrically conductive org. polymer having cation capturing ability as a second electrode in the soln. is electrochemically reduced to capture cations in the soln. with the second electrode. Since the amt. of hydroxyl ions in the soln. is reduced by generating gaseous oxygen, the pH of the soln. is lowered. The concn. of ions in the soln. is lowered because cations in the soln. are captured by polyanions doped into the org. polymer.

IPC: H01L21/3065
Filed: 1991-10-15
Abstract: PURPOSE:To equalize the plasma density distribution by a method wherein plasma in even density distribution in the title system is produced in the electric field generated by electrodes provided in the sidewall parts of the system as well as in the magnetic fields generated by the solenoid coils provided on the outer periphery of the electrodes. CONSTITUTION:Even magnetic fields are generated by solenoid coils 2 while the space between side electrodes 1 and 1 is impressed with high-frequency by the second high-frequency power supply 6 to produce plasma. Next, when a cathode electrode 4 loaded with a wafer 7 is impressed with high-frequency by the first high-frequency power supply 5, this high-frequency leads out activated ion seeds produced in the high density plasma in even density distribution by the electric field generated between sidewall electrodes 1 and 1 by solenoid coils 2 so as to be led-into a wafer 7. Through these procedures, the high density plasma in even density distribution can be produced to evenly produce the activated ion species thereby enabling both etching rate and etching shape to be equalized.

Filed: 1988-10-20
Abstract: PURPOSE:To eliminate the problem of vignetting of lens and the problem of generation of a line-bow and to provide the compact laser scanning optical system by providing the 1st lens which condenses the luminous flux transmitted through a condenser lens in a sub-scanning direction and makes this light incident to a reflecting surface and the 2nd lens which puts the light axis together to a reference plane and images the luminous flux reflected by the reflecting surface on a photosensitive face. CONSTITUTION:The luminous flux LB shot from a laser generator 1 is condensed in the main scanning direction and sub-scanning direction by the condenser lens 2 and is then further condensed only in the sub-scanning direction by a cylindrical lens 3. This luminous flux is imaged as a line image onto the reflecting surface 4a of a rotary polyhedral mirror 4. The incident luminous flux LB on the reflecting surface 4a diagonally from below is reflected diagonally upward symmetrically with a reference plane X and is refracted diagonally downward by a troidal lens 5, by which the luminous flux is condensed in the sub-scanning direction and an imaging point 7 is scanned in an arrow c direction on the surface of a photosensitive drum 6. Since there are no things to hinder the progression of the reflected light in this way, the problem of the so-called vignetting of light is eliminated. The locus of the imaging point is straight and the generation of the so-called line-bow is eliminated. The compact laser scanning optical system is thus obtd.

Title: Crt display/lcd display conversion circuit
Inventor: GOTO YUTAKA
IPC: G09G3/36
Filed: 1996-09-17
Abstract: PROBLEM TO BE SOLVED: To improve plotting performance by providing a plotting position detecting and holding circuit and reducing frequency of using display access. SOLUTION: A plotting position detecting and holding circuit 8 detects occurrence of writing (plotting) for data for CRT display and a plotting position by an address and a control signal outputted from a memory control circuit 6, and sets a plotting occurrence flag corresponding to a plotting position. When the plotting flag corresponding to its rewriting address is not set for rewriting request of data for LCD display from a LCD display control circuit 5, a rewriting request signal is mastered, and it is prevented that the rewriting request signal is not delivered to a memory control circuit 6. Also, when the plotting flag is set, the rewriting request signal is delivered to the memory control circuit 6 as it is, and when plotting is finished at the same time, plotting is cleared. Therefore, a rate of access for display is reduced, and a rate of access for plotting can be relatively increased.
