IPC: G11C27/02
Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To amplify a voltage without making a stationary current flow by setting or releasing both terminals of two capacitors connected to the source and drain electrodes of a MOS transistor respectively to a prescribed potential difference and changing the potential difference between the gate and source of the MOS transistor from the outside. SOLUTION: A switch 105 is turned OFF, the switch 107 is turned ON and the voltage VG is applied to the gate electrode of an N type MOS transistor 103, that is the input node 108 of this circuit. Then, when the switch 107 is turned ON while keeping the switch 105 OFF, the potential of a node 104 becomes VC-TTH+ΔVG and changes for ΔVG from a precharge stage similarly to the potential change of the gate electrode of the N type MOS transistor 103. At the time, a charge amount transferred from an output capacitor 102 to a storage capacitor 101 becomes ΔQ=CT.ΔVG. Then, the terminal voltage of the output capacitor, that is the potential of an output node 106, changes for ΔVO=-CT.ΔVG/CO and thus, the amplification of an amplification factor -CT/CO is performed.

IPC: G03F7/038
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To form a resist pattern having desired apertures so that a resist does not remain in grooves and pores surrounded by light shielding materials which hardly transmit the exposure light by making a part to form the resist apertures into an exposure light shielding part using a negative resist. SOLUTION: Such a Si substrate 10 is formed by a regular method, that is covered by an oxide film 11 on the surface and is provided with pores each having 0.25 μm width and 1.25 μm depth. Si is opaque to the light of 365 nm. A negative resist 12 is applied onto the Si substrate 10, which is then irradiated with the exposure light 14 through a lens using a mask 13 which makes the part to be implanted into the light shielding part and subsequently developed to form a resist aperture part 15. Since the pores are so small as to have 0.25 μm width and 1.25 μm depth, i.e., 5 aspect ratio, the resist does not remain in the pores so that the resist aperture can easily be formed. The implantation is then performed. By this method, the impurities can be diffused into the desired pore parts.

IPC: C10B45/02
Filed: 1983-08-31
Abstract: PURPOSE:To obtain coke for metallurgy with improved productivity, which has excellent strength, by briquetting blended coal to give a specified cake density and dry-distilling the briquette. CONSTITUTION:In dry-distilling blended coal having appropriate average rank of coalification and appropriate max. fluidity, said blended coal is briquetted to give a cake density of 0.90-1.05. By compacting the blended coal, an increase in the quantity of the coal to be fed into a coke oven by 20-40% can be achieved, as compared with conventional methods. Thus, even when the dry distillation time is prolonged thereby, productivity can be improved. Particularly, with regard to productivity, an operation of a higher oven wall temp. becomes possible by compacting. For example, when the bulk density is 0.75T/m<3> and the oven wall temp. is 950 deg.C in a convention method, DI15<30> is 91.1, while when the bulk density is 1.00T/m<3> in the present invention, DI15<30> can be increased to 93.6 at the same oven wall temp. of 950 deg.C.
