IPC: H01L21/20
Filed: 1992-03-26
Abstract: PURPOSE:To provide a method for forming a semiconductor device where transposition density is reduced, and mechanical strength of an acting layer is strengthened. CONSTITUTION:For a growing substrate 1 is used a silicon substrate which is of 2cm<2> and has thickness of 100mum, and is off from the direction of (100) toward the direction of (011). In0.5Ga0.5As1mum of a medium layer 2 is made grow on the surface of the growing substrate 1. The In0.5Ga0.5As has lower rigidity than GaAs of an acting layer 3. On the surface, GaAs 2mum of the acting layer 3 is made grow. Next, sixty four etching windows of each 5mum<2> on the side of the growing substrate are formed with a gap of 200mum each, by using photo-resist. Then etching is applied to the growing substrate 1 with the use of mixed solution of hydrofluoric acid and nitric acid, and openings 51 are formed. The area of each etching window is narrower than that of an element forming region 4 of the acting layer 3, or the same as the region. The semiconductor substrate formed in this way is heat treated at temperatures ranging from 600 deg.C to 900 deg.C, for 15 minutes, at the atmosphere of AsH3.

Abstract: PURPOSE:To always accurately measure the present position of a vehicle by obtaining the movement quantity of sampling timing corresponding to that during a wave disappearance by using distances between a wave disappearing position or a signal restoring position and loran stations. CONSTITUTION:A calculated position from a calculated position selecting circuit 22 is normally delivered to a between-two-point distance calculating circuit 30 and, only when a tracking is enabled again, to another between-two-point distance calculating circuit 32. Using an absolute position that has been obtained just before a wave disappearance and the positions of loran stations that have been stored in a station position storage circuit 34 in advance, the circuit 30 obtains distances between the absolute position and the loran stations. Using a relative position obtained just before a wave restoration and the stored (34) positions of the loran stations, the circuit 32 obtains distances between the relative position and the loran stations. A sampling timing movement quantity calculating circuit 36 obtains differences between the circuits 30 and 32 for the respective loran stations and, on the basis of the differences, obtains the movement quantities of the sampling pulses of the tracking points of the loran stations from the wave disappearance to the wave restoration. The sampling pulses move to a normal tracking point based on a calculated movement quantity when a wave is restored.

Title: Communication equipment and communication method
Inventor: MATSUMOTO WATARU
IPC: H04J11/00
Filed: 1999-04-12
Abstract: PROBLEM TO BE SOLVED: To provide communication equipment which can efficiently transmit data while compatibility with other countries is kept by dividing a system for transmitting incoming/outgoing data by frequency division and a system for transmitting incoming/outgoing data by time division by means of a prescribed frequency as a threshold and transmitting data. SOLUTION: Interference noise by a TCM-ISDN communication system usually occurs much at 1.1 MHz and below. Consequently, in a frequency band which easily receives interference noise by a TCM-ISDN communication system, data is transmitted by a TDD system and data is transmitted by an FDD system in a frequency band above it. A system for transmitting incoming/outgoing data by frequency division and a system for transmitting incoming/outgoing data by time division are divided by 1.1 MHz as the threshold and data is transmitted. Thus, interference noise by the TCM-ISDN communication system is avoided and data can efficiently be transmitted.
