Title: Semiconductor base material and method of manufacturing the same
Inventor: OKAGAWA HIROAKI
IPC: H01L21/205
Filed: 1999-11-26
Abstract: PROBLEM TO BE SOLVED: To avoid various problems caused by ELO growth using ordinary mask layers and, in addition, to simplify the manufacturing process of a semiconductor base material. SOLUTION: In this method of manufacturing a semiconductor base material, a substrate 1 having a growing surface made on an uneven surface and masks 3 formed on the recessed surface 12 of the growing surface as shown in Fig. (a) is used. When vapor growth is made by using the substrate 1, crystal growth occurs only from the tops of the projecting sections 11 of the growing surface due to the masks 3. At starting the crystal growth, therefore, crystal units 20 only occur as shown in Fig. (b), when the crystal growth is continued, films grown in the lateral direction from the tops of the projecting section 11 are joined together, and finally, cover the uneven surface of the substrate 1 by leaving cavity sections 13 as they are, in the recessed sections 12 as shown in Fig. (c).  In this case, low dislocation areas are formed in the laterally grown sections, namely, above the recessed sections 12, and the quality of the formed film is improved.

Title: Automatic channel selection afc circuit
Inventor: TAKAYAMA NORITSUGU
IPC: H04N5/44
Filed: 1991-12-19
Abstract: PURPOSE:To individually set up an AFC characteristic capable of sufficiently securing frequency deviation compensating capacity for normal operation and an AFC characteristic for automatic channel selection by reducing the load impedance of an AFC circuit at the time of automatic channel selection and switching the AFC characteristic for the normal operation and the AFC characteristic for the automatic channel selection. CONSTITUTION:At the normal operation, an AFC characteristic changing switch 1 is OFF and a tuner AFC changing switch 12 is connected to the AFC circuit side. Its AFC characteristic increases the resistance values of resistors 7, 8 and sufficiently increases AFC gain. At the time of automatic channel selection, the switch 1 is ON and the switch 12 is connected to the fixed voltage side. Thus the AFC characteristic for automatic channel selection can be obtained by adding resistors 2, 3 as load resistors.

Title: Phase variable frequency dividing circuit
Inventor: TAKIGUCHI YOSHIRO
IPC: H03K23/64
Filed: 1991-12-19
Abstract: PURPOSE:To set a variable step width of the phase of an output signal with a small-scale and simple circuit by providing a counter, a comparing means, and an output control means. CONSTITUTION:A counter 11 divides the frequency of an input signal, and an output control means 15 outputs this frequency division output at the output timing obtained by a comparing means 13, therefore, the frequency of the output signal is equal to the frequency of the frequency division output. The output timing is variably set in accordance with the result of comparison between the counted value outputted from the counter 11 and a value given as the select signal by the comparing means 13. Consequently, the shift register which delays the signal preliminarily obtained by frequency division in many stages and the selector which selects the output of this shift register in a conventional circuit are not used to directly generate the output signal, which has the phase varied in accordance with the select signal, while keeping the frequency division ratio constant.
