Title: Production of silicon dioxide coating film
Inventor: SAKAI YASUTO
IPC: C03C17/25
Filed: 1992-09-28
Abstract: PURPOSE:To obtain a dense silicon dioxide coating film free from fine bubbles by dissolving metallic aluminum in the aq. hydrosilicofluoric acid soln. practically saturated with silicon dioxide to make the soln. supersaturated with silicon dioxide and dipping a substrate in the soln. free from metallic aluminum. CONSTITUTION:Metallic aluminum is dissolved in the hydrosilicofluoric acid practically saturated with silicon dioxide, and the soln. supersaturated with silicon dioxide is brought into contact with a substrate to deposit a silicon dioxide coating film on the substrate surface. In this case, metallic aluminum is previously dipped and dissolved in the aq. hydrosilicofluoric acid soln. practically supersaturated with silicon dioxide to make the soln. supersaturated with silicon dioxide, the metallic aluminum is then removed from the processing soln., and the substrate is dipped. By this method, the bubbles of gaseous hydrogen generated at the time of dissolving metallic aluminum are not generated when the coating film is produced, and hence a dense silicon dioxide coating film not contg. bubbles is produced.

Abstract: PURPOSE: To reduce the costs of equipment by reducing the number of parts and simplifying the constitution. CONSTITUTION: In an optical disk 1, a detection part for indicating whether the optical disk is a magneto-optical disk or a compact disk is provided and a CPU 13 detects it. The CPU 13 controls a laser driver 11 through a laser control circuit 9 so that laser power matches up to the kind of a detected optical disk and at the same time performs the changeover control of the amplification factor of a current/voltage conversion circuit 3 for performing the current/ voltage conversion of a reproduction signal from a photodetector and amplifying it so that the amplification factor matches up to the kind of a detected optical disk.  Thereby, the difference of the amplitude of the reproduction signal, which is generated due to the difference in reflectivity, can be corrected to be able to completely eliminate a gain control circuit provided at the subsequent stage of the current/voltage conversion circuit 3.

Title: Drive device of piezoelectric actuator
Inventor: UCHIYAMA HIROMITSU
IPC: H02N2/00
Filed: 1989-10-03
Abstract: PURPOSE:To prevent unneeded power consumption and heat build-up by executing discharge only during the discharging period which is determined being based on a charge voltage value and an applied voltage value and then performing feed-back control of the generated displacement to a target displacement when discharging of the piezoelectric actuator charging electric charge is needed. CONSTITUTION:A polarity switching/charging.discharging part 90 controls a drive voltage Vp of a piezoelectric actuator 9a. For example, in the case of a command value Vi>=0, a H signal is constantly output to a transistor Trc and switching from the charging state of the piezoelectric actuator 9a to the discharge state is performed by switching the output to the transistor Tra from 'H' to 'L' signal and the output to the transistor Tre from 'L' to 'H' signal. Also, the discharge period can be determined uniformly by the output period of the L signal or H signal to be output to the transistors Tra and Tre. Thus, the generation displacement of the piezoelectric actuator 9a is fed back for control to follow the target displacement.

Title: Dram refleshing method
Inventor: RII JII FURIIDOMAN
IPC: G11C11/406
Filed: 1992-09-03
Abstract: PURPOSE: To give the method for reducing the dropping of a current to a computer which accompanies the refreshing of numerous DRAMs. CONSTITUTION: A computer generally includes various forms of DRAMs (dynamic random access memory), namely DRAM 1 and DRAM 4, and DRAMs need periodical refreshing so as not to lose their data. However, as a large current is dropped to the computer if simultaneous refreshings are made, refresh signals 10 to 13 are distributed to distribute refreshing timewise. Consequently, refreshings are executed not simultaneously, and the dropped current is prevented from superposing to make a single large surge current.

Title: Baking method for resist
Inventor: NAKAMURA SHINICHI
IPC: G03F7/40
Filed: 1986-10-29
Abstract: PURPOSE:To enable the heating to a desired temperature for a short time for only a part too close to a boundary surface between a resist and a substrate, by effectively radiating laser rays on this boundary surface. CONSTITUTION:Laser beams emitted from a laser beam source 1 are made to pass through a lens system 2 and reflected on a vibrating mirror 3 and radiated on a surface of a substrate 5 coated with a resist 4. Then, the laser beams are focused by a lens system 2 so that a focusing point comes too close to a boundary surface between the resist 4 and the substrate 5. while the beams are vibrated with a full swing angle in the X direction of the substrate by the vibrating mirror 3, the surface of the substrate 5 is uniformly scanned with laser beams by moving a XY table 6, on which the substrate 5 is mounted, in the Y direction synchronously with the vibration in the X direction, so that the surface of the substrate is uniformly heated. Hence, the part of the boundary surface between the resist and the substrate can be heated limitedly to a desired temperature for a short time.
