Title: Manufacture of single crystal
Inventor: INOUE SHIYOUICHI
IPC: C30B15/00
Filed: 1980-08-21
Abstract: PURPOSE: To prevent the occurrence of crystal defects due to droplets in the manufacture of a high purity single crystal by the Czochralski method by removing droplets produced at the bottom of a single crystal before they are solidified.  
     CONSTITUTION: A quartz crucible 23 is mounted on a rotary shaft 24 in a reactor 21, and starting material 27 for a single crystal is put in the crucible 23. The material is melted with a heater 22, and a seed crystal 28 is dipped in the melt 27. While rotating the crucible 23 and the crystal 28, the melt 27 is cooled slowly, and the crystal 28 is pulled up little by little. A single crystal 34 is grown at the tip of the seed crystal 28 to manufacture a high purity single crystal. When the crystal 34 is pulled up by about 60W70% of the melt 27, it is separated from the melt 27, and droplets produced at the bottom of the crystal are removed with a removing tool 32 before they are solidified by cooling. Thus, a high quality single crystal free from crystal defects due to droplets can be manufactured.

Title: Same frequency channel 2-way radio transmission system
Inventor: SUZUKI HIROSHI
IPC: H04B1/54
Filed: 1987-05-11
Abstract: PURPOSE:To simplify the constitution of a radio equipment of an opposed radio station by applying control to compensate a delay distortion in a received wave at the reception and applying control at the transmission to be kept to a transfer function at the reception just before the transmission. CONSTITUTION:A radio wave received by an antenna 14 during a period of transmission from a station A to a station B is demodulated by a demodulator 16 via a transmission/reception switch circuit 32. Since waveform distortion is caused in the demodulation signal by the delay difference in plural radio wave transmission lines, the distortion is eliminated by a reception equalizer 33 to suppress the deterioration in the transmission characteristic. On the other hand, during a period of the transmission from the station B to the station A, the modulation wave is equalized in advance by a transmission equalizer 34 at the base band and the radio wave is radiated from the antenna 14 via the transmission/reception switch circuit 32. Thus, the equalizer is integrated to the one station B and the other station A is realized economically.

IPC: B22D11/045
Filed: 1980-08-25
Abstract: PURPOSE:To produce ingots of good quality requiring no straightening at high efficiency by forming a cope as a movable mold which is freely repulsively approachable to a drag. CONSTITUTION:Molten steel 3A from a tundish 1 is in the state of expanding slightly while forming a solidified layer 3B in a fixed shape mold 9, and therefore it contacts with the entire inside surfce of the mold and is cooled roughly uniformly by the water in a water cooling jacket 11.

CONSTITUTION:Boron is implanted in the upper face of a p type Si substrate 1 for forming a channel cut layer 2. Subsequently, a 11mum thick sputter SiO2 film 3a is formed thereon. The sputter SiO2 film 3a is then provided with an aperture 4, through which arsenic is implanted to form an n<+> type burried collector layer 5. After that, Si is caused to epitaxially grow selectively so as to have a thickness of about 12mum. The Si film is then polished to reduce the thickness to 10mum and to flaten the surface. In this manner, an active region isolated by the SiO2 film is obtained. Since the active region thus obtained has a thickness as large as 10mum, an element having a sufficiently high pressure resistance can be obtained.
