Title: Digital demodulator
Inventor: IKEDA YASUNARI
IPC: H04L27/38
Filed: 1993-07-26
Abstract: PURPOSE:To provide the digital modulator and demodulator for orthogonal frequency modulation in which an accurate phase of a DFT time window signal is obtained. CONSTITUTION:A discrete Fourier transformation circuit 121 applies discrete Fourier transformation to a received orthogonal frequency multiplex signal to demodulate the signal. A discrete Fourier transformation circuit 171 is used to exclusively generate a time window signal and has the similar function to that of the discrete Fourier transformation circuit 121. A time window signal generating circuit 174 generates a time window signal DFT 1 to the discrete Fourier transformation circuit 121 and a time window signal DFT2 to the discrete Fourier transformation circuit 171 based on the transformation result of the discrete Fourier transformation circuit 171. The time window signal generating circuit 174 always obtains the optimum phase of the time window signal by changing the phase of the time window signal DFT1 to match the phase to that of the time window signal DFT2 when the phase of the time window signal DFT1 is deviated from the proper phase to keep the phase of the signal without giving an undesired phase change to the time window signal DFT1.

Title: Electronic typewriter system
Inventor: HARA TOSHIMASA
IPC: B41J5/30
Filed: 1987-07-22
Abstract: PURPOSE:To enable the efficient use of a typewriter, by a method wherein, in the system rise, an electronic typewriter is used in a normal manner, an input manner is selected between an input per character and a batch input per line by a CC/LL switch, and the input information is identified by a CRT. CONSTITUTION:When a text key 8 is pressed in the system rise, the signal transmits through an interface circuit 2. Thus, a CPU reads the program in a memory 4 and changes over a typewriter mode to a screen editor mode. Moreover, the sentence is displayed and edited to a CRT 6 by a CRTC 5. If the text key 8 is not pressed, the system operates with the typewriter mode because the signal for changing over the mode is not issued. In this case, a character input manner can be selected between an input per character and a batch input per line by a CC/LL SW 7. When the CC/LL SW 7 is turned either on the CC side or on the LL side, the CPU 3 judges whether a flag rises at a point 4a of the memory 4 by the signal transmitting through the interface circuit 2. Thereafter, the CPU 3 conducts either the input per character or the batch input per line while the CRTC 5 displays one line to the CRT 6.

Filed: 1995-07-20
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method which can easily increase storage capacitance without increasing the number of processes and step-difference, regarding a semiconductor device having various kinds of electrodes like a DRAM. SOLUTION: An electrode layer 26a is formed (A). In this dry etching process (B), the superfluous electrode layer 26a is eliminated by etching, and the working surface 26b of the exposed electrode 26 is roughened. Before the electrode layer 26a, a stopper layer 22 is formed, and the roughening of a surface is performed by etching, while the etching condition is so adjusted that a protective layer to be formed on the working surface 26b of the electrode 26 can be easily eliminated (for example, oxygen flow rate is increased, or applied high frequency power is decreased), and successively by a specified amount of over etching under the same condition. This electrode working method can be applied to the manufacturing of a semiconductor device having a stack type or a fin type or a cylindrical type storage capacitor, e.g. what is called a DRAM, and capacitor formation is ended.

Title: Exposure control device for color copying machine
Inventor: TANAKA TORU
IPC: G03G15/043
Filed: 1984-09-04
Abstract: PURPOSE:To reduce a color difference generated in continuous copying operation and to improve detecting accuracy by correcting a power supply voltage to be supplied to an exposure lamp in the succeeding process by a surface potential detecting value of a setting part of a developing machine, and when the deviation between a reference value and the surface potential of the succeeding process exceeds an allowable value, compensating the power supply voltage moreover. CONSTITUTION:A surface potential detecting signal at a position of the developing machine 9a is compared with a reference signal obtained from a correcting reference voltage generating circuit 21 by a comparator 22 through a detecting circuit 20. If a difference is generated between both the values, the detected signal is corrected, and when the signal is included in a control objective level, development is executed. The voltage value of an exposing power supply 26 is previously corrected so that the difference between the detecting signal of the surface potential of the position of the developing machine 9b in the succeeding developing process which is formed by a density pattern 31 and a reference signal becomes almost the same as the difference between the detecting signal of the preceding developing process and the reference signal by multiplying the latter difference by a positive correction factor. If the difference between the detecting signal of light potential at the position of the developing machine 9b and the reference signal exceeds the control objective level, the difference is multiplied by the 2nd correction factor to correct the power supply voltage and to control the voltage value of the exposing power supply 26.

Abstract: PURPOSE:To effectively grow a film by introducing raw material gas to the plasma of plasma forming gas, different from the raw material gas for growing the film, under a state where the plasma is sustained thereby decomposing the raw material gas and forming active species. CONSTITUTION:A substrate 16, on which a film is to be grown, is disposed in a film growing chamber 5 at a position facing with a plasma forming chamber 1 in the film growing chamber 5 under a state where the interior of the chamber 5 is evacuated and stabilized. Then, Ar gas is introduced into the forming chamber 1 through a plasma forming gas introducing pipe 3 under control of a mass flow controller MFC. Then Ar plasma is formed by introducing microwave and applying magnetic field through current supply to a coil. In this case, cleaning of the substrate 16 proceeds and if even a very small amount of Si is deposited during film growth in the forming chamber 1, etching effect thereby takes place. Thereafter, raw material gas of Si, e.g. Si2H6 or SiH3, is introduced through a gas introducing pipe 8 and an opening 8a thereof. Then control by the MFC is carried out to obtain a film having desired thickness.

Abstract: PURPOSE:To increase the heat capacity of a ring-carrier for the heat received from molten metal via fins for enhancing the welding strength between the ring-carrier and a piston body, by casting the ring-carrier equipped with fins on its surface inside the piston body so as to be fixed. CONSTITUTION:On the top 2 of a piston body 1 a cavity 3 is formed, and further in a top-land part 4 a ring-carrier 5 equipped with a ring groove 6 is provided.

Title: System and method for computation
Inventor: TIMOTHY A ELLIOT
IPC: G06F7/483
Filed: 1997-07-10
Abstract: PROBLEM TO BE SOLVED: To make it possible to calculate sticky bits and calculate a function of a guard bit speedily by using a mask and an intermediate result instead of a normalized intermediate result, and calculating the function of the guard bit and calculating the sticky bit simultaneously with normalization. SOLUTION: A system 100 has the intermediate result 112 of floating-point calculation and a mask 114 as inputs. The intermediate result is matched with the mask 114 by using a matcher 113. The matcher 113 matches the starting bit of the mask 114 with an (n+1)th bit of the intermediate result 112. Thus, the system 100 uses the intermediate result 112 and the mask 114 used for the normalization. Consequently, operation performed by the system 100 can be carried out almost at the same time with the normalization. Therefore, delay due to calculation after the normalization of the sticky bit and the function of the guard bit can be reduced.
