Filed: 1980-05-15
Abstract: PURPOSE:To detect the presence or absence of any original on contact glass while an original pressure plate is held closed by forming transparent electrodes on the contact glass, providing plural pieces of electrodes to the undersurface of the original pressure plate and conducting these. CONSTITUTION:A thin-film-like transparent electrode 2 is formed on the surface of contact glass 1. Plural pieces of electrodes 5 are provided to the undersurface of an original pressure plate 3 in such a manner as to contact originals 4 of various sizes when said originals 4 are placed on the prescribed position on the glass 1, so that when there are no originals 4, the electrodes 5 contact the electrodes 2 and conduct to form a closed circuit. If all the electrodes 5 conduct when the plate 3 is held closed upon ending of copying, it is indicative of the absence of the original on the glass 1. When the conduction of, for example, the two electrodes 5 on the undersurface of the plate 3 is blocked, and the other two electrodes 5 not in contact with the original 4 contact the electrode 2, the conduction state can be controlled as compared with full conduction and therefore the remaining of the original is easily detected.

Title: Manufacture of semiconductor device
Inventor: YOSHIOKA KENTAROU
IPC: H01L21/3205
Filed: 1981-05-01
Abstract: PURPOSE:To improve productive yield and reliability of a semiconductor device of Al multilayer wiring structure, by etching a lower Al wiring masked by an alumina film, over-hanging, and burying and insulation film with a use of it. CONSTITUTION:An Al layer is formed on an insulation layer 12 of a semiconductor substrate 11. Its surface is oxidized to make an alumina film 14. A lower wiring 16 is formed by etching with a mask of resist pattern 15. The alumina film 14 is overhung thereupon. Next, insulation films 17e, 17f on a resist 15 become uncontinuous to the other parts 17 because of the overhung alumina film 14, and are easily lifted off, when an insulation film 17 is formed on its surface. An insulation film 18 and an upper wiring 19 are formed afterwards. This eliminates disconnection or shortcircuit in multilayer wiring, because the surfaces of lower wiring layers 16, 17 are flat.

IPC: H03M1/12
Filed: 1991-03-07
Abstract: PURPOSE:To reduce power consumption required for voice encoding processing by interrupting the voice encoding processing or decreasing the number of waves for operating clock in a silent state. CONSTITUTION:A mode switch 10 supplies an operating mode instruction to a voice encoder 5 when a flag representing the presence of voice (sound) is set by a voice presence/absence detecting flag(VAD flag) from a voice detector 6, and supplies an idle instruction to the voice encoder 5 when the silent state is set. In such a way, voice encoded data is outputted to intermittent transmission equipment 7 with the VAD flag at a frame of sound, and only the VAD flag is outputted to the intermittent transmission equipment 7 at a frame of silence. Also, a clock frequency switching circuit is provided, and a fast clock is outputted as the operating clock by the VAD flag from the voice detector 6 in a sound state, and the operating clock is outputted by switching to a slow clock in the silent state. Thereby, it is possible to reduce wasteful power consumption required for the voice encoding processing in the silent state where no voice is present.

Filed: 1986-03-24
Abstract: PURPOSE:To reduce scars on a silicon wafer by casting a lapping surface table of spherical graphite cast iron while cooling only a surface to be used for the lapping process, thereby improving capability of maintaining the flatness and durability of the lapping surface table itself. CONSTITUTION:Into a sand mold 6 with a chiller 5 inserted on a lapping surface 1 side and with an insulation member 7 on the other attachment surface 3 side, molten cast iron 8 having weight ratios (%) of C: 3-3.8, Si: 2-2.9, Mn: 0.3-0.9, P: 0.05 or less and residue: Fe is poured. With this method, spherical graphite cast iron which is to become a lapping surface table solidifies from the lapping surface 1 side toward the attachment surface 3 side. As a result, part which solidifies last and is liable to produce shrinkage cavity or gas hole or to include foreign matter is driven to the neighborhood of the attachment surface 3. Thus, capability of the lapping surface table itself maintaining flatness and durability is improved and occurrence of scars on lapped objects such as silicon wafer is extremely reduced.

Title: Chatter prevention device for boring tool
Inventor: TSUZUKI SADAAKI
IPC: B23B47/00
Filed: 1986-03-24
Abstract: PURPOSE:To enable the prevention of a boring tool chatter by providing a lever having a weight pressing the external surface of a quill cylinder on gravity in such a way that the lever is floatable about an axial line orthogonal with the axis of the rotation of the quill. CONSTITUTION:A coupling member 40 comes down actuated with a cylinder device and one end at the side of the doubler 35 of a lever 34 is caused to move upward about a support axis 33. In this state, a workpiece 'W' moves upward and a quill 13 advances together with a spindle head 10, with a cutting tool 14 turned upward. Thereafter, the quill 13 passes through a boring hole Wa and the forward end of the quill 13 is supported by a supporter 21. Then, the workpiece 'W' is lowered and the coupling member 40 is moved upward, thereby causing the fall of the doubler 35 to such a level as getting in contact with the quill 13 for processing the boring hole Wa. The doubler 35 is in slidable contact with the quill 13 and exposed to a downward force due to a weight 36, thereby preventing the chatter of a boring tool 12. Even if the quill 13 is exposed to a force exceeding the load of the weight 36, this weight 36 works in such a direction as cancelling a repeat displacement and the chatter of the boring tool 12 stops immediately.

Abstract: PURPOSE:To prevent the choking of a fuel injection valve and the deterioration of the flow characteristic, by employing an air chamber around the tip section of a fuel injection valve at the stopping side while injecting the clean air at the upstream of a throttle valve from the air chamber during the partial cylinder operation and preventing the E.G.R. from contacting to the tip of the valve. CONSTITUTION:A fresh air stopper valve 5 will close during the partial cylinder operation to stop the fresh air to the stopping side cylinders D, E, F while simultaneously an E.G.R. valve 12 will open to return the exhaust gas to the stopping side cylinders D, E, F. While simultaneously the fuel supply from the stopping side fuel injection valves (d), (e), (f) is stopped and the clean air at the upstream of a throttle valve 2 is led through a lead-in tube 28 into the air chamber 17 formed around the tip section 16 of the valve 16. Said air is injected through a fuel lead hole 29 in the direction of a suction tube 31 while covering the tip section 16 of said valves (d), (e), (f). Consequently the exhaust gas returning through the cylinders D, E, F will never intrude to contact with the tip section 16 of said valves (d), (e), (e) thereby the tip section 16 is maintained clean continuously.
