Title: Printer
Inventor: HASHIMOTO YASUYUKI
IPC: B41K1/02
Filed: 1988-10-28
Abstract: PURPOSE:To provide a single-stroke operation type printer by a construction wherein when a main body of a stamp is moved forward, a printing part first makes contact with an ink.pad, then an ink.pad case and the main body moved together forward against an appropriate resisting force, and when a cap is opened, only the main body is moved forward, without making contact with the ink.pad, to a position where stamping can be performed. CONSTITUTION:When the rear end 3b of a main body 3 of a stamp is pushed against a compression spring 2 to move the main body 3 forward, a printing part 3a is brought into contact with an ink.pad 4d. Next, an ink.pad case 4 is slidden forward to a predetermined position, against a frictional resistance between the case 4 and a reduced diameter part 1c. When the ink.pad case 4 is moved forward through release of the contact thereof with the reduced diameter part 1c, the case 4 is instantaneously opened by a compression spring 7b, resulting in an uncapped condition. Subsequent to the uncapping (or cap- opening) operation, the printing part 3a of the main body 3 is protruded from a forward opening 1a, and the main body 3 is further moved forward, whereby the printing part 3a is brought to the tip of an outer cylinder 1, resulting in a condition in which printing can be performed.

Title: Formation of interlayer connecting body of interlayer insulating film
Inventor: NAKANO HIDEKAZU
IPC: H01L21/3205
Filed: 1987-10-26
Abstract: PURPOSE:To flatten a polycrystalline silicon film by a method wherein a buried polycrystalline silicon film inside a through hole made in an insulating film on a substrate where a semiconductor device has been formed is removed, the polycrystalline silicon film is oxidized and this silicon oxide film is etched back. CONSTITUTION:In order to lower a resistance value of a polycrystalline silicon film 4, an impurity is diffused after which, a polycrystalline silicon film 5 in a part buried in a through hole 3 is removed and the polycrystalline silicon film 4 is oxidized up to a boundary of an SiO2 film 2. During this process, even when a boundary between the buried polycrystalline silicon film 5 and the SiO2 film 2 is situated at a part lower than the upper end of an opening, there is no big difference in an etching rate between a silicon oxide film 6 and the SiO2 film 2 as an interlayer insulating film; on the other hand, an etching operation of the polycrystalline silicon film does not progress. By this setup, even when the buried polycrystalline silicon film 5 is etched up to its interface, an opening part of the through hole 3 does not subside as compared with its neighborhood and film can be flattened.

Abstract: PURPOSE:To select only a stable video image without defocusing as an output video signal by selecting any of plural picture data supplied within a unit field period. CONSTITUTION:An object image is formed to a CMD (charge modulation device) 3 as an image pickup element via an image pickup lens 1 and an aperture 2, an image pickup processing circuit 4 applies prescribed image pickup processing to an output electric signal from the CMD 3 to provide an output of a video signal. The video signal is converted into digital video data by an A/D converter 5 and stored in a memory 6 as, e.g. 1 field data. The video data from the A/D converter 5 are fed to an exposure control section 12 and an AF (automatic focus) control section 13, which moves the image pickup lens 1 to a focal position based on AF information obtained from the video data. Thus, a fogged picture cannot be outputted by selecting AF information by which an maximum contrast is obtained among plural sets of AF information (contrast component) obtained from the video data.
