IPC: H04L27/38
Filed: 1994-11-08
Abstract: PURPOSE: To precisely detect the symbol discrimination point of a signal, which is modulated by a multi-subcarrier demodulation system, in a short time. CONSTITUTION: A temporary symbol discrimination point detecting means 18 detects a temporary symbol discrimination point g2 of a received signal which is modulated by the multi-subcarrier modulation system and a temporary symbol demodulating means outputs the signal value of the temporary symbol discrimination point of the demodulated signal (b) of each subcarrier obtained by demodulating the received signal as a temporary demodulation symbol d2 .  The phase difference Δθ between the phase of the temporary demodulation symbol at a predetermined prescribed position of the outputted received signal and the phase of a reference symbol at the prescribed position of a reference received signal is detected, the time error Δt from the reference symbol discrimination point g0 of the temporary discrimination point g2 is found from the detected phase error Δθ of each subcarrier and the frequency ω of the subcarrier, and the temporary symbol discrimination point is corrected on the basis of the time error.

Abstract: PURPOSE:To obtain a GaAlAs epitaxial wafer whose luminous wavelength is constant and luminous effect is high by a method wherein turbulance on a surface of a GaAs single, crystal substrate is eliminated, and a smooth and uniform epitaxial growth layer is obtained. CONSTITUTION:At epitaxial growth, at first solvent or solute 2 not containing Al is placed on a substrate 1 and the surface of the GaAs substrate 1 is subjected to melt-back keeping at constant temperature and for constant period. After that, a p-type solvent 3 is placed on the substrate 1 sliding a slider 10 and is cooled at prescribed cooling speed, then epitaxial growth is performed to a p-type GaAlAs layer 2a or the surface of the GaAs substrate 1.

Title: Method for driving moving partition
Inventor: NEGAMI KIYOSHI
IPC: E05F15/14
Filed: 1990-10-12
Abstract: PURPOSE:To smooth the turning action of a partition panel by changing the driving torque of front and rear motor-driven runners at the initial and final periods of the turn of the partition panel at a hanger-rail bent portion. CONSTITUTION:A partition panel P having motor-driven runners R1, R2 is hanged on a hanger rail HR provided with a branch line and a direction- changing rotary device RY. Limit switches LS1, LS2 are disposed at the entrance and exit of the rotary device RY respectively and also torque controllers 11, 12 for the runners R1, R2 are provided. When the panel makes a turn the position of the runner R2 or R1 is detected by the switch LS1 or LS2 according to the direction in which the panel travels. Then the controllers 11, 12 are actuated and driving torque of the rear runner is lowered to below that of the front runner at the first period of the turn, while driving torque of the front runner is lowered to below that of the rear runner at the final period. Harmful sliding of the panel can thus be prevented and also the panel can be easily stopped and smoothly make a turn.

Title: Graphite parts for pulling up single crystal
Inventor: KANO MASATO
IPC: H01L21/208
Filed: 1994-11-09
Abstract: PURPOSE: To prevent the failure of a graphite crucible by forming a projecting part in the bottom of the graphite crucible and/or in the central part of a graphite receiving base, forming a space around the projecting part and bringing the base of the graphite crucible and the front surface of the graphite receiving base into contact with each other by the projecting part. CONSTITUTION: The projecting part 13 is formed in the bottom of the graphite crucible 11 of the graphite parts 10 for pulling up the single crystal constituted by including the graphite crucible 11 and the graphite receiving base 14. The space part 15 is formed around the projecting part 13. Since the base of the graphite crucible 11 and the front surface 14b of the graphite receiving base are brought into contact with each other by the projecting part 13, the center of the base of the graphite crucible 11 is supportable by the projecting part 13. Since the application of expanding force on the bottom of the graphite crucible 11 is prevented, the generation of the failure, such as chipping or cracking, in the bottom of the graphite crucible 11 is prevented.  The melt temp. in the quartz crucible is maintained uniform by the heat insulating effect of the space part 15 around the projecting part 13 and, therefore, the rotating speed of the quartz crucible is lowered and the elution of oxygen atoms into the melt from the quartz crucible is suppressed. The concn. of the oxygen atoms contained in the single crystal to be pulled up is thus lowered.
