Abstract: PROBLEM TO BE SOLVED: To attain increase in a variable power rate with a little lenses by providing 1st and 2nd lens groups having a positive refraction factor in order from the side of an object and a 3rd lens group having a negative refraction factor, and satisfying a specified condition. SOLUTION: A lens system is composed of 1st and 2nd lens groups G1 and G2 having the positive refraction power in order from the object side to an image side and a 3rd lens group G3 having the negative refraction power. In the case of changing a focal distance from a wide angle end state to a telescopic end state, all the lens groups G1-G3 are moved to the object side so that the interval of 1st and 2nd lens groups G1 and G2 can be increased and the interval of 2nd and 3rd lens groups G2 and G3 can be decreased. The 1st lens group G1 is composed of a cemented doublet L1 having a negative lens and a double convex lens, the 2nd lens group is composed of a double concave lens L21, negative lens L22 and double convex lens L23 and the 3rd lens group G3 is composed of a positive lens L31 and a negative lens L32. An aperture stop S is provided on the image side of the convex lens L23.  Then the condition of 0.25<D/f2<0.50 is satisfied. In this inequality, D and f2 express the thickness and focal distance of the 2nd lens group G2 along with an optical axis direction.

Title: Manufacture of semiconductor
Inventor: SUGINO SHIGEYUKI
IPC: H01L21/302
Filed: 1986-05-20
Abstract: PURPOSE:To improve a boundary state from a thin film formed in later steps by substituting etching gas for gas containing hydrogen after etching step with gas, and then forming a thin film, such as an insulating film, a semiconductor film or a metal film. CONSTITUTION:After a wafer is placed on a tray 3, inner air is evacuated, and chlorine gas (Cl2) from a gas box 7 is fed into a chamber. Then, an ultraviolet ray is generated from a light source 5, and emitted by a reflecting mirror 6 to the surface of the wafer 2. The chlorine gas partly becomes radical by the energy of the ultraviolet ray to etch a single crystal silicon on the wafer 2 to dry clean it. Then, the chlorine gas is exhausted, and hydrogen gas is fed into the chamber 1, and substituted for a hydrogen gas atmosphere in the chamber. Thus, the end group of the Si substrate becomes H atoms. Then, after H2 gas is exhausted, the O2 gas is fed from the box 7 into the chamber 1. The wafer 2 is then heated by a heater 4 to form an oxide film on the wafer 2.

Title: Active matrix type display panel
Inventor: YAMASHITA SEISUKE
IPC: G02F1/136
Filed: 1987-05-13
Abstract: PURPOSE:To obviate generation of a disconnection defect in display driving elements by interposing insulating layers between all of the metals of connecting layers and the metal oxide films of picture element electrodes or driving electrodes. CONSTITUTION:A single metal, such as aluminum, having a high tendency to ionization is used for the connecting layer 41. The insulating layer 60 is interposed between the connecting layer 41 and one electrode 10 to cover the circumferential edge part 51a of the connecting layer 41 in a region 51 where the connecting layer 41 and the one electrode 10 overlap on each other. Erosion of the metal oxide films used for the picture element electrodes, etc., at the time of etching is, therefore, obviated even if the aluminum or the like having the large tendency to ionization is used independently as the metal for the connecting layer. The generation probability of the disconnection defect in the display driving element is thereby greatly decreased.

Filed: 1988-05-16
Abstract: PURPOSE:To accurately measure beta rays by providing a gamma-ray transmissive beta-ray shield body at the intermediate position between two beta-ray plastic scintillators and inputting the beta rays to a subtracter after removing noises. CONSTITUTION:The beta rays in radiatray which is made incident into a housing 9 are transmitted through a beta-ray plastic scintillator 10 and then shielded by the beta-ray shield body 12, and only gamma rays remaining at a plastic scintillator 11 for background measurement on the opposite surface side are made incident, thereby emitting fluorescent light to the gamma rays as a background which reach the plastic scintillator 11 for background measurement.

Title: Wave and wind energy take-out plant
Inventor: TSUCHIYA MAKOTO
IPC: F03B13/22
Filed: 1981-07-27
Abstract: PURPOSE:To efficiently take out energy by use of interaction of wave and wind by inducing up and down wave motion inside a tower shell which is immersed under water surface and by applying air pressure which is generated by use of the wave motion thereto for amplification of the up and down motion and taking wind pressure inside from the upper part of the tower shell. CONSTITUTION:The uppermost wind inlet opening 14 of a shell tower A-1 is changeable in direction so as to be opposed to wind direction. If a wind pressure stands over a certain value, a check valve 22 is opened to let air into a supply pipe 26. When the water level W rises under the influence of undulation, a screw propeller 32 is rotated to drive a screw pump 41. A descending current is resultingly brought about inside the shell tower A-1 and blast of air is forcibly released from a pilot nozzle 45 so that a valve lid 21 is turned in the closing direction and an inner pressure is simultaneously increased to open a check valve 24, thereby allowing air current to flow into a blast pipe 27. On the other hand, when the water level W descends, said propeller 32 and pump 41 are reversed, on account of which air is blasted from the nozzle 44 to open the valve lid 21. Wind pressure is thereby developed to depress the water level W.
