Title: Switching regulator circuit
Inventor: NAGAO YASUYOSHI
IPC: H02M3/156
Filed: 1981-08-20
Abstract: PURPOSE:To decrease a ripple voltage component of a DC output voltage and radiation noise, by additionally providing an inverter, a switching transistor (TR) and a reactor for a known circuit. CONSTITUTION:A TR8 and a reactor 9 are added to a load current supply path and a diode 3 is inserted between a connecting point of the TR8 and the reactor 9 and ground. With a TR1 turned on, the current in a reactor 2 starts increasing. During this increase, the TR8 is turned off and an output voltage +V0 is decreasing, but the speed of decrease of the +V0 is slow due to the current flowing to the reactor 9. Thus, with the TR8 turned on, a positive voltage induced in the reactor 2 is given to a load via the TR8 and the reactor 9 as a DC output current. In this case, the current flowing to the reactors 2 and 9 starts decreasing. During this decrease, the output voltage +V0 is increasing.

Title: Plasma etching method
Inventor: TATSUMI TETSUYA
IPC: H01L21/3065
Filed: 1995-05-29
Abstract: PURPOSE: To prevent the difference in conversion of dimension and occurrence of loading effect, in the plasma etching using a resist mask in the shape of a reversed taper. CONSTITUTION: The upper shoulder part of the resist mask 5 with a fine width which is shaped like a reverse taper by resist in the line of negative chemical amplification, etc., is sputtered, and a sputtering product is stuck again to the sidewall on inclination side so as to form a sidewall stacked film 6 by carbon polymer. By this treatment, the sidewall on inclination side of the resist mask 5 is shaped into roughly vertical form. Then, plasma etching is applied to the layer to be etched. Hereby, at the time of plasma etching of the layer to be etched, since there is no section which becomes a shade against the incidence of ions, the sidewall deposited film by reaction products never adheres thick to the side face of the resist mask. Accordingly, a pattern faithfull to the shape of the faired resist mask can be formed.

Title: Encoding/quantizing method for audio signal
Inventor: ARAKI SADAFUMI
IPC: G10L19/00
Filed: 1999-05-12
Abstract: PROBLEM TO BE SOLVED: To suppress deterioration in sound quality by repeating processing for satisfying the restriction on the number of usable bits at every block and processing for satisfying the restriction on allowable error level. SOLUTION: When the number of necessary bits becomes not more than the number of usable bits, all information bits amp[sfb] showing whether the value of a normalized coefficient sf[sfb] at every divided band changes or not in divided band sfb are initialized to '0'. The quantized error level in the divided areas sfb when an audio signal is quantized by a common normalized coefficient Csf and a normalized coefficient sf[sfb] at that time is obtained. When the divided area sfb where quantized error level becomes not less than the allowable level exists, the normalized coefficient sf[sfb] in the divided area sfb is increased by '1' and the information bit amp[sfb] is set to be '1'. Then, electronic error level is obtained again and processing is repeated until quantized error becomes less than the allowable error level on all the divided areas sfb.

Abstract: PURPOSE:To prevent adsorbing capability of activated carbon from being lowered, by controlling ozone injection ratio on the basis of a detected value of the total amount of organic matters having a molecular weight of not less than 1,000 contained in water to be treated. CONSTITUTION:Water 1 to be treated which has been subjected to a biochemical treatment and separation by flocculation is fed into a receiving tank 2, and is supplied into a reaction tank 5 for ozone oxidation by a water pump 3 through a detector 4. The detector 4 detects the total amount of organic matters having a high molecular weight of not less than 1,000 contained in water to be treated with ozone. After an ozone injection ratio is determined by a calculator 6 on the basis of the value detected by the detector 4, ozone is fed from an ozonizer 7 into the reaction tank 5 through a diffuser pipe 8, and is brought into reaction with water to be treated through gas-liquid contact. The water thus oxidized by ozone is fed into a dissolved ozone decomposing tank 10, where unreacted ozone contained in the water is brought into self-decomposition.
