Filed: 1988-12-21
Abstract: PURPOSE:To obtain an input coupler for a carbon dioxide gas laser light hollow waveguide in which power capacity can be largely increased by providing an iris type exciting waveguide between a focusing lens for receiving a laser and the hollow waveguide. CONSTITUTION:A laser output light 1 from a carbon dioxide gas laser is focused by a lens 2, and introduced into a hollow waveguide 3 through an iris type exciting waveguide 6. The inner diameter 2a of a circular opening 7 n the iris type exciting waveguide 6 is so selected as to satisfy the following relationship, where z is a distance from the incident end of the hollow waveguide 3, a formula a<2>=ao<2>{1+[lambdaz/pir<2>ao<2>]} where lambda is oscillation wavelength of the carbon dioxide gas laser light, and r is a value in a range of 0.4-0.6. When a distance between the openings 7 of an iris is d, the value of d is determined when the Fresnel number N of the opening 7=a<2>/(lambdad) is 5 or more. As a result, it operates to convert the gauss type beam distribution by efficiently removing only the reverse phase of the amplitude distribution of the incident beam to reduce the quantity of generated heat near the incident end, and since the heat generation is distribution, an increase in the power capacity can be expected.

The dial transmission section 4 sends a dial signal corresponding to the automatic key input to a telephone line 1 and outputs a high or low level mute signal to a base of a transistor(TR) 6 from a mute signal output terminal 5 when all the dial signals are finished for the transmission. Thus, the TR 6 is turned on or off and a signal corresponding to the on/off of the TR 6 is given from the emitter to the control section 3 as the dial transmission end detection input. The control section 3 receives the input to discriminate it as the end of the transmission of dial signal and enters the line connection standby state to the opposite telephone set.

Abstract: PROBLEM TO BE SOLVED: To form a memory device on a glass or plastic substrate at a low temperature and, at the same time, to enable the memory element to hold information for a long time. SOLUTION: The storage area 15 of a memory device is composed of many scattered fine particles (dots) 15a and, at the same time, the surface density of the particles 15a is made higher than that of structural holes (pinholes) produced in a tunnel insulating film 14a. Alternatively, the number of the particles 15a in the storage area 15 is adjusted to >=5 or the conductive area 13c of the memory element is formed of a polycrystalline silicon layer 13 having surface roughness of 0.1-100 nm and, at the same time, the number of the particles 15a in the storage area 15 is made larger than the number of crystal grains in the conductive area 13c.  When such a defect as the pinhole, etc., occurs in the tunnel insulating film 14a of the memory device and the charges stored in part of the particles leak out, the charges stored in the fine particles formed in the defectless area do not leak out. Therefore, the memory device can hold information for a long time.
