IPC: G03F1/68
Filed: 1996-04-24
Abstract: PROBLEM TO BE SOLVED: To control the accuracy of the pattern dimension in the longitudinal and lateral directions of a fine pattern to within the allowance and to suppress the increase in the pattern number to irreducible minimum by discriminating a part where the distance between adjacent patterns formed almost in the resolution limit region is smaller than a specified dimension, discriminating an edge part, and correcting the pattern to be wider than the one to be exposed. SOLUTION: The mask patterns to be exposed are inspected to judge whether the interval W between adjacent mask patterns is smaller than the resolution limit owing to the wavelength of light or not (a). If the interval W is smaller than the resolution limit, a new pattern having larger width than the original pattern is made to form (b). The mask pattern is inspected to judge whether the width of the mask pattern is smaller than the resolution limit owing to the wavelength of light or not. If the width is smaller than the resolution limit, the edge part of the pattern is separated from the original pattern and a new pattern having larger width than the original pattern is made to produce (c).

Title: Forming process of deposited film
Inventor: NISHIMURA YUKIO
IPC: H01L31/04
Filed: 1984-05-22
Abstract: PURPOSE:To form a deposited film containing silicone atom at high filming speed while sustaining high quality at low energy level by means of utilizing heat energy at low level as exciting energy. CONSTITUTION:A cyclic halogenated silicate represented by a structual formula: SinX2n [where X and (n) respectively represent halogen atom and integer of 3- 6] and gaseous atmosphere of hydrogen are formed in a vessel containing a substrate, while those compounds are supplied with heat energy to form a deposited film containing silicon on said substrate. The cyclic halogenated cilicate shown by the formula is the halogen derivative of the hydrogenated silicate (cyclic silane compound) SinH2n, a highly stable compound to be produced easily. The (n) value is limited to the integer of 3-6, since the larger the (n) value, the easier the decomposition but the harder the evaporation and the synthesis while deteriorating the efficiency of decomposition.

Title: Purifying method of hydrochloric acid
Inventor: HAYASHI KENICHI
IPC: B01D19/00
Filed: 1981-07-03
Abstract: PURPOSE:To remove SO2 in an aqueous solution of HCl almost completely by easy operations, by bringing the aqueous solution of HCl containing SO2 into contact with an inert gas. CONSTITUTION:Hydrochloric acid containing dissolved SO2 is brought into contact with an inert gas, e.g. air, to accompany the inert gas with SO2, which is removed from the hydrochloric acid. The concentration of the hydrochloric acid need not be particularly limited, but when the high concentration is too high the  HCl gas is released by the gas-liquid contact operation and the HCl gas is contained in the inert gas. The too low concentration increases the total amount  of the liquids, and both cases are not desirable. The operation temperature  need not be particularly limited, but the too high temperature increases the  vapor pressure of the HCl, which is accompanied by the inert gas.

Filed: 1986-05-06
Abstract: PURPOSE:To precisely execute motion correction by using one remaining motion vector signal even if at least the two of the motion vector signals transmitted from the transmitting side three times repeatedly are in the condition of not being able to correct errors. CONSTITUTION:When it is judged that a motion vector signal remains within the range of being able to correct errors at least once, while the motion vector signals are transmitted three times in a control circuit 28, a switch 22 is inputted in a forecasting circuit 26 as soon as the output of a detection circuit 27 is selected and outputted from an output terminal 25 as the motion vector signal of the present field. When it is judged that all the motion vector signals transmitted three times repeatedly are not able to correct errors, the switch 22 is switched so that the motion vector signal forecasted from the past motion vector signal which is the output of the forecasting circuit 26 may be used as the alternative of the motion vector signal of the present field. Thus the motion corre-ction is executed precisely.

IPC: H04S5/00
Filed: 1993-04-06
Abstract: PURPOSE:To obtain a clear difference of positional feeling of the acoustic images between the cases where the position of an acoustic image is set at the front and the back of a listener respectively. CONSTITUTION:The acoustic image position of a sound is decided with operations of a direction dial 9a and a distance slider 9b of an acoustic image position controller 9. Thus a control parameter generator 10 outputs the signals Tl and Tr which control the delay time, the signals Cl and Cr which control the amplitude, and an F/B signal which switches the position of an acoustic image between the front and back sides respectively based on an angle signal and a distance signal D. Based on these various control signals, a prescribed time delay difference and amplitude difference are applied to an audio signal ASL. Then the phase of both channels is inverted by an inverter 7 in response to the signal F/B in order to secure the acoustic image position of the back side.

Title: Performance measuring apparatus for converter
Inventor: ISHIUCHI SUSUMU
IPC: G04D7/00
Filed: 1987-04-27
Abstract: PURPOSE:To enable measurement without causing measuring errors whether ICs for a timepiece is mounted or not, by using a circuit made up of an analog switch, a diode and a relay switch in place of a specialized IC. CONSTITUTION:Analog switches 1a-1d control current flowing through a bipolar converter. In a timepiece with timepiece ICs mounted, relay switches 3a and 3b are separated for measurement, leaving only parasite diodes for timepiece ICs connected. In a timepiece with no timepiece ICs mounted, the switches 3a and 3b are connected to measure and diodes 2a-2d are used instead of parasite diodes for timepiece ICs. With such an arrangement, a condition where the parasite diodes for timepiece ICs are connected can be simulated by controlling the switches 3a and 3b. This enables measurement free from measuring errors with the connection of none of the timepiece ICs.
