Title: Reflex objective lens
Inventor: KOUCHIWA TAIRA
IPC: G02B13/24
Filed: 1980-09-09
Abstract: PURPOSE:To obtain 100% aperture efficiency while holding a high contrast with a wide angle of view by correcting aberrations by arranging three positive, negative and positive lenses from a common object and image space side and a concave reflecting mirror having a reflecting surface facing the common object and image space side, and by making the lens system meet specific requirements. CONSTITUTION:The 1st positive lens L1, 2nd negative lens L2, 3rd positive lens L3, and a concave reflecting mirror M having a concave reflecting surface facing the side of common object and image space 1 are arranged successively from the side of space 1, and while the surface of the 2nd negative lens at the space 1 side is convex to the space 1 side, the lens system meets requirements shown by conditional inequalities (a)-(e). Consequently, various aberrations are corrected excellently, a high contrast is held over the entire plane of an an-use angle of view, and aperture efficiency is increased up to 100% even at the circumferential part of an image-formation screen.

Title: Metallic thin film forming method
Inventor: AWAYA NOBUYOSHI
IPC: H01L23/52
Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To enable a metallic thin film made of copper alloy to be formed at low cost by removing a thin film made of copper. SOLUTION: A metallic thin film is removed by chemico-mechanical polishing process so as to leave metallic parts 102a only in the recess of inversed patterns 105. Next, a copper thin film 107 is formed on the metallic parts 102a by depositing copper using sputtering process, etc. Next, the whole body is heated at 400 deg.C for exceeding 30 min to make the metallic parts 102a and the copper thin film 107 react with each other for interdiffusion. Resultantly, copper alloy wirings 108 are to be formed of metallic thin film made of copper alloy. Next, the copper thin film 107 is removed by chemico-mechanical polishing process so as to form the copper alloy wirings 108 on an interlayer insulating film 104 through the intermediary of a harrier layer 106.  Through these procedures, the wiring layers made of copper alloy can be formed without heating over the allowable temperature (450 deg.C) in the large scale integrated circuit(LSI) wiring forming step and applying the high pressure of 100 MP.

Title: Plate discharging box for stencil printer
Inventor: KOBAYASHI KAZUYOSHI
IPC: B41L13/14
Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To reduce the contact resistance against the wall surface when a mass of used master is pushed out by tapering the section for storing the used master while compressing to be enlarged gradually in the discharging direction. SOLUTION: When the storing section 35 of a plate discharging box 21 is filled with a used master 8d, an operator draws out a plate discharge box 21 from a machine frame and pushes out a mass of used master 8d in the axial direction from the storing section 35 using a push-out member 40. Since the compressed mass of used master 8d in the storing section 35 is tapered along the wall surface thereof, a gap appears due to the difference of diameter between the wall surface of the storing section 35 and the used master 8d when the push-out member 40 is moved slightly. Consequently, the force of the used master 8d is weakened in the direction for pushing the wall surface of the storing section 35. Since the contact resistance incident to subsequent push-out is decreased significantly the mass of the used master 8d can be pushed out with a light operating force.

Abstract: PURPOSE:To report simply and easily that the quantity of a residual developer recovered into a storage part reaches a prescribed value, by reporting that the stored value of the replenished frequencies of developer reaches a prescribed value. CONSTITUTION:When a density detecting sensor 46 detects a toner density lower than a prescribed value, the sensor 46 outputs a high-level signal to a control circuit 20, and the circuit 20 drives a replenishing device 45 to replenish the toner. If the density is not raised to a set value or higher for a certain time, the circuit 20 judges that the toner does not exist in a hopper 44, and the circuit 20 drives a warning display lamp 21. Each time the toner is charged into the hopper 44, the circuit 20 adds ''1'' to the contents of a memory device 22. The circuit 20 discriminates whether these contents reach a prescribed value (m) or not; and when they reach the value (m), the circuit 20 lights a maintenance and inspection display lamp 24. By this lamp 24, the maintenance and inspection (replacement) time of a filter bag 13 is detected.
