Title: Manufacture of mask blank for x-rays
Inventor: KAWADA MASARU
IPC: G03F1/22
Filed: 1989-06-29
Abstract: PURPOSE:To markedly increase safety when compared with a CVD method by a method wherein, using a sputtering method for formation of a nitride film on a wafer substrate, the heating temperature of a wafer substrate is set within the specific range of the melting point (centigrade) of the nitride, and a chemically stabilized state is obtained. CONSTITUTION:When the melting point of a nitride, from which a film is formed, is set at Tm and the temperature when the film is formed is set at T, a pole-like structure in the temperature region of 0.1<T/Tm<0.3 is considerably ravelled out, and a temperature at which tensile strength will be increased can be present. A nitride film can be formed by conducting a magnetron sputtering method wherein a mixed gas formed by mixing argon and nitride into sputtering gas is used. As the melting point of boron nitride is 3000 deg.C, substrate temperature should be in the range of 300 deg.C to 900 deg.C. As the melting point of silicon is 1414 deg.C even when a film is formed on a silicon wafer, the silicon wafer itself is never melted in the above-mentioned temperature range.

Title: Separation of fatty acid
Inventor: MAIKERU TERENSU KURIARII
IPC: C07C67/00
Filed: 1983-09-12
Abstract: Oleic acid is separated from a feed mixture comprising oleic acid and linoleic acid by contacting the mixture at separation conditions with a molecular sieve comprising silicalite, thereby selectively retaining the oleic acid, removing the linoleic acid and recovering the oleic acid from the molecular sieve by displacement with a displacement fluid. The feed mixture may also contain rosin acids, in which case a first molecular sieve comprising silicalite is used to separate the fatty acids from the rosin acids. It is preferred that the displacement fluid comprise a liquid having a high polarity index and that the molecular sieve comprise silicalite dispersed in a silica matrix. A particularly preferred and novel molecular sieve comprises silicalite in a silica matrix and derived from a precursor comprising silicalite powder dispersed in colloidal amorphous silica, said precursor having been gelled and then treated in a manner effecting substantially complete elimination of hydroxyl groups on the molecular sieve.

Abstract: PURPOSE:To quickly perform an air deflating operation by connecting a pump mechanism for discharging air to the outside to an air escape hole mounted on the wall portion of a cylinder. CONSTITUTION:In case of deflating air contained in oil fed into a cylinder 2, a clip 19 is detached to move a piston 8 to be pulled outward, and a gap 17 on the trailing end side is passed through a groove 21. At this time, the interior of a cylinder 6 gets to negative pressure, so that air bubbles in the cylinder 2 are discharged with oil through an air escape hole 5, the groove 21 and the gap 17 to the base of the cylinder 6. Subsequently, the piston 8 is pushed toward the base of the cylinder 6, so that air bubbles and oil in the cylinder 6 are discharged from a vent hole 9 through a discharge port 16 of a one-way valve 15 to the outside. Thus, air bubbles in the cylinder 2 are gradually discharged with oil to the outside by reciprocating the piston 8.

When the error exceeds the tolerance, the curve is divided into two, to be repeated until the error reaches the tolerance by treating the respective ones as a new input. The original curve is developed by connecting the endpoint of respective divided curves. Thus, the curve can be divided and developed at high speed.

Title: Synchronous and asynchronous decision method and device for viterbi decoding signal
Inventor: BAEK JONG SEOB
IPC: H03M13/41
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To decide a synchronous/asynchronous state of a decoding signal by tracking inversely the path where a convolutional coded receiving signal passed in its transmission mode. SOLUTION: Since the data undergo the convolutional coding via two shift regjsters, the inverse tracking registers 42 to 45 are needed for the inverse tracking of initial states 00 to 11 respectively. Each of registers 42 to 45 searches for a survival path corresponding to the initial state of every register for an inverse tracking memory 41 where the signals unaergone the Viterbi decoding via a Viterbi decoder, so that every corresponding data is inputted to each input terminal din. Then a comparator 46 compares the output value of registers 42 to 45 with each other in every cycle, and a synchronous state is decided if the initial states of registers 42 to 45 are coincident with each other after the lapse of a fixed cycle. If no coincidence is confirmed among those initial states, an asynchronous state is decided.

Title: Automatic gain control circuit
Inventor: TSUJI YASUHIKO
IPC: H03G3/10
Filed: 1984-08-13
Abstract: PURPOSE:To suppress fluctuation of an output dynamic range by providing a diode to a load of a differential amplifier to keep a current flowing to the diode to a constant value thereby making an output DC potential of the differential amplifier constant. CONSTITUTION:An automatic gain control circuit consists of two differential amplifiers 20, 22 and a current compensation circuit 24. A constant current is given to diodes 34, 36 as a load of the amplifier 20 from constant current source 38, 40 respectively. Although the operating current of the amplifier 20 is changed by a control voltage from a control input terminal 44, the change in the operating current is compensated by a current compensation circuit 24. As a result, the output DC potential of the amplifier 20 is kept constant. Since the output of the amplifier 20 is fed to the amplifier 22 having a constant amplification gain, the output DC potential is kept constant. Thus, the output DC potential is made constant and the fluctuation of the output dynamic range is suppressed.
