Title: Manufacture of semiconductor device and semiconductor device
Inventor: NAKAJIMA KENJI
IPC: H01J1/304
Filed: 1999-10-15
Abstract: PROBLEM TO BE SOLVED: To provide a cone whose aspect ratio is large and whose tip is thin, and to provide the manufacture method of the cone. SOLUTION: Impurity, for example, oxygen, is introduced to a silicon substrate or a silicon layer and it is heat treated. Thus, an impurity deposition region is formed and high selective ratio anisotropic etching is executed with the deposition region as a micromask. Thus, a substantially sharp and thin needle-like cone where the micromask is set to be a top, an aspect ratio is about 10 and a diameter near a tip is about 10 nm-30 nm is obtained. When a drive electrode, such as an insulating layer and a gate electrode, is formed around the cone, the cone can be used as a field electron discharge element, a high-frequency switch element and the probe of a scanning-type microscope.

Title: Voice concealing communication system
Inventor: AZUMA MITSUHIRO
IPC: H04L9/06
Filed: 1985-12-26
Abstract: PURPOSE:To remove the generation of an error due to cipher pull-out even if instantaneous quality deterioration such as hit is generated in a transmission line by transmitting cipher synchronizing information prior to the start of communication to synchronize a voice concealing communication system, and then self-traveling a block cipher unit on the receiving side on the basis of self- synchronization during the transmission and operation of voice cipher data. CONSTITUTION:Prior to the transmission of cipher data, data of n bits in an output n-bit shift register 6 are sent to an input n-bit shift register in each bit and stored in an input n-bit shift register 9 on the receiving side 2', and during the transmission and operation of the voice cipher data, the block cipher unit 10 on the receiving side 2' is self-traveled on the basis of the self- synchronization. Since the cipher synchronizing information is transmitted prior to the start of the voice concealing communication and the block cipher unit 10 in a deciphering device 2' is self-traveled on the basis of the self- synchronization after starting the voice concealing transmission, the generation of an instantaneous trouble in a transmission line 3 does not exert influence upon the cipher synchronizing information and the influence is not spreaded.
