Abstract: PURPOSE:To improve a lightning-proof property and strength of an electric cable, and prevent the fusion breaking by a thunderbolt, by stranding plural lightning-proof strands consisting of a steel core material and a covering material made of aluminum or an aluminum alloy around a main cable as an electric wire or an earth wire and eccentrically placing the core material inside the covering material for at least one strand among them. CONSTITUTION:An electric cable is composed of an overhead earth-wire 1 containing an optical fiber of the outside diameter 5mm and one strand 2 and five strands 2a stranded around the overhead earth-wire 1. The strands 2, 2a are made nearly to be a sector in the cross sections and stranded together to form the outside diameter of 10.5mm and cover around a pipe 5. The strands 2, 2a are composed of respective steel core materials 6, 6a and covering materials 7, 7a made of aluminum or an aluminum alloy which are formed by covering the core materials 6, 6a around. A portion which is the large circular side of the strand 2 in the covering material 7 is of 2.5mm in the thickness and of 5.5mm in the maximum width and made thicker than that of the other strands 2a, accordingly its outer edge is protruded like a fin, and the core material 6 is placed in a deflected position from the center of the strand 2 to the small circular side. With this constitution, the protrusion of the covering material 7 functions as a fusion loss allowance against a thunderbolt.

Title: Electron-beam exposure
Inventor: UEMA TAKEARI
IPC: H01L21/302
Filed: 1978-12-12
Abstract: PURPOSE: To prevent a film from expansion and shrinkage after development and to obtain a fine pattern, by varying the amount of dose of an electron beam or the width of the pattern described by the beam depending on the thickness of a resist film caused by the concave and convex portions of a substrate.  
     CONSTITUTION: In obtaining a pattern with a uniform width by eliminating swelling and thinning of the pattern caused by the concave and convex portions of the foundation, at first, a negative resist film is applied on the foundation. Then, the amount of does or the width of the mask pattern are varied depending on the film thickness. If the amount of dose is decreased, the absorption energy is decreased, the developing surface retreats, and the swelling of the pattern can be prevented. That is to say, at the portion with a thickness of 2μm, the amount of does is decreased by ΔD; and at the portion which is in the vicinity of a step portion 7 and whose thickness is thin, the amount of does is increased by ΔD'. Or, the pattern width which is described by an electron beam may be decreased at the swelling portion and increased at the thinning portion.

IPC: H01L21/20
Filed: 1990-06-15
Abstract: PURPOSE:To readily obtain a superfine structure by approaching an object at a lower temperature than that of a substrate to the surface of the substrate at a high temperature, jumping up atoms or molecules forming the substrate according to thermal fluctuation and gradually adsorbing the atoms or molecules on the object at the lower temperature.

Title: Noise elimination circuit
Inventor: KAKIMOTO TAKASHI
IPC: H04N5/93
Filed: 1986-07-02
Abstract: PURPOSE:To eliminate residual noise and distortion of waveform by providing the 1st H.P.F whose cut-off frequency is variable and the 2nd H.P.F whose cut-off frequency is fixed so as to mix each output signal in opposite phase close to that of an original input signal. CONSTITUTION:An output of a H.P.F 18 is multiplied by a factor of B by an amplifier circuit 19 and the noise is also amplified by B. An output signal of a limiter circuit 13 and an output signal of the amplifier circuit 19 are inputted to a mixer 14 in opposite phase respectively and subtracted with each other. As a result, a signal (f) is obtained, a large signal level of the input video signal is eliminated completely and a small signal level such as noise is attenuated by a multiple of (1-B). Further, the noise extracting band of the output signal from the mixer 14 is limited toward higher frequencies by an L.P.F 15. In giving the signal to a mixer 16, where it is mixed with the original input video signal in opposite phase, a video signal (g) is obtained. Thus, the signal distortion having a comparatively large signal change is eliminated and a large noise rejection effect is obtained.

Abstract: PURPOSE:To prevent the forgetting of cutting off of the main electric power source switch by changing, retaining and controlling a main electric power source circuit of a device main body to be in an 'on' condition by a paper feeding base first position conversion detecting signal, and to be in an 'off' condition by a paper feeding base second position conversion detecting signal, of a paper feeding base position detecting means. CONSTITUTION:A micro switch 100, which is provided in the front part of a printer front cover 2 as the position detecting means for a paper feeding base 5, at the time when a printer is not in use, detects that the paper feeding base 5 is folded and contained in the front part of the front cover 2 and is in a second position, and retains the main electric power source circuit of the printer to be in an 'off' condition. Further when the paper feeding base 5 is folded out as the paper feeding base from the front part of the front cover 2 for the use of the printer, that is converted to the first position, the conversion to the first position of the paper feeding base 5 is detected and the main electric power source circuit of the printer is switched to an 'on' condition. Thus the electric waste and the effect on the service life of the device is prevented from the forgetting of cutting off the electric power source after the use of the device.
