Title: Clamp pulse generation circuit and multi-scan display device
Inventor: NOGUCHI HIROSHI
IPC: H04N5/18
Filed: 1995-05-23
Abstract: PURPOSE: To accurately reproduce a color by generating the clamp pulses corresponding to output forms or frequencies of various synchronizing signals to perform accurate clamping. CONSTITUTION: An output (b) of a synchronous processing circuit 5 is inputted to a duty factor control circuit 2 to fix the duty, and its output (c) is inputted to a duty factor variable control circuit 3 to control the duty. Next, an output (d) of the duty factor variable control circuit 3 is inputted to a monostable multivaibrator 4, and the waveform is shaped into a pulse width required for clamping to obtain a clamp pulse (e). Since a reference voltage can be changed by a reference voltage control circuit 12 to change the duty factor of the output (d) of the duty variable control circuit 3, the phase of the clamp pulse (e) can be adjusted. Thus, the clamp pulse capable of accurate clamping is obtained.

On the outside of the lower end or an intermediate part of the indent 3, an adding plate 4 which is formed into a shape having an arc cross section with the same radius of curvature as the arc of the body part 2, is arranged on the same surface as the body part 2 so that it may form a dummy body part of the container main body 1.  They are integrated by engaging and connecting them with each other, and a pocket 5 of which the upper end is opened, and where a printed matter A such as a statement of virtues, an explanation and others, is housed, is formed. In this case, the lower end of the indent 3 becomes the bottom of the pocket.

Abstract: PURPOSE:To remarkably reduce the generation of rust on a metal member by making the cleanness of nonmetallic inclusion of the metal member less than or equal to a specified value, in a package for accommodating a semiconductor element wherein the metal member is attached on the outer surface of an insulating vessel accommodating an element. CONSTITUTION:In a package accommodating an element, an insulating base body 1 and a lid body 2 are composed of electric insulating material like alumina ceramic, and an insulating vessel 3 is constituted of the base body 1 and the lid body 2. A recessed part for accommodating a semiconductor element 5 is formed at the central part of the upper surface of the base body 1. An outer lead terminal 7 soldered with the upper surface periphery of the base body 1 connects an element 5 in the inside and an external circuit. Said terminal 7 is composed of kovar (Fe-Ni-Co alloy) and the like. Nonmetallic inclusion mixing with the kovar is made less than or equal to 0.05% with respect to the nonmetallic inclusion cleanness defined by JISG-0555. Thereby oxide of oxygen scavenger is not exposed on the outer surface of the terminal 7, so that the outer surface of the terminal 7 is completely coated with a plating metal layer, and rust is not generated when salt water attaches on the terminal 7.

Title: Mechanical seal
Inventor: INOUE KOU
IPC: F16J15/34
Filed: 1978-10-09
Abstract: PURPOSE: To hermetically seal an internal fluid even if the pressure of the internal fluid is lower than that of an external fluid, by forming a following ring in a shape that a retainer loaded through a spring for providing with initial seal-up surface pressure and a revolution-stop mechanism can be moved in the axial direction.  
     CONSTITUTION: At the initial stage when the pressure P 1  of an internal fluid begins to become lower than the pressure P 2  of an external fluid, seal-up force instantaneously lowers owing to the push force of a spring 7, and leakage is not produced. When differential pressure ΔP between the pressure P 1  of the internal fluid and the pressure P 2  of the external fluid is further enlarged in the negative direction and seal-up force becomes to zero, a retainer 12 moved in the right direction in the figure because an end surface 12'C of the retainer 12 is subject to differential pressure. An end surface 12' b of the retainer 12 compresses the spring 7, contacts with the back of a following ring 4 and pushes the following ring 4 against a seat ring 3. Thus, the following ring 4 maintains a seal-up surface in conjunction with the seat ring 3.

Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To improve both the efficiency and accuracy of a color information addition job by showing the range of an optimum size on a display when the color information is added to the pasteboard image data. SOLUTION: A processor 3 stores a pasteboard in a storage 1 as the read pasteboard image data via a pasteboard input device 5. An area, where the color information on the pasteboard image data is added, is registered on a status table and a degree of complexity of the pasteboard is calculated. Thus, the area of the pasteboard to be shown on a display 2 is decided. The color information is added to the pasteboard image data via an instruction input device 4 based on the designation of a layout. Then the pasteboard image data including the color information is registered again on the status table. If a cumulative size of the area where the color information is added is smaller than a prescribed rate, a screen is scrolled to the area adjacent to the display area shown on the display 2 and shown there.

Abstract: PURPOSE:To inspect a pattern without malfunction even if patterns are image- picked up together with the pattern to be inspected by comparing and inspecting the interval between character strings. CONSTITUTION:It is assumed that the interval between the 1st and 2nd character strings 103 and 104 is SP1 the interval between the 2nd character string 104 and the edge 105 of an object 1 to be inspected is SP2, on the other hand the interval between character strings 103 and 104 is SP1 and the interval between character strings 104 and 106 is SP2. SP1<SP2 means that there are two character strings, and SP1=SP2 means that there are three character strings. Even if there are the pattern to be inspected 101 and the unnecessary pattern 102, the measurement of only the SP1 and SP2 can prevent the pattern 102 from triggering malfunction.

Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To reduce the height of residual camber after leveling in a roller leveler for straightening camber caused at top and rear ends of a metal plate after hot rolling. SOLUTION: A group of lower rollers 1, 3 are moved in the advancing direction of the metal plate 5 from the position of equal pitch to a groups of upper rollers 2, 4 and respective distances in the advancing direction of the metal plate between the upper and lower rollers 1, 3 and 2, 4 which are opposed to each other are made smaller than a half of the roller pitch. Thus, the leveling of the upward camber generated at the top end of the metal plate 5 is executed with the rollers 2, 3, 4 and the leveling of the downward camber generated at the rear end is executed with the rollers 1, 2, 3 by their inverse bending action, so leveling of the small amount of the residual camber is possible. In this way, the threading of plate in a heating or cooling device for heat treatment is facilitated and uniform heat treatment is enabled.

Abstract: PROBLEM TO BE SOLVED: To prevent particles remaining in a chamber from dropping onto a substrate by causing a depositing gas mixture to flow into the chamber under a reaction condition, in order to deposit a solid compound layer on the internal surface of the chamber, before a depositing process onto the substrate. SOLUTION: First of all, a plasma CVD chamber is cleaned by a gas containing fluorine. Hydrogen plasma is generated in a chamber 113 to remove fluorine residues. Plasma of a silicon compound precursor gas is then generated. Next, a solid silicon compound is deposited inside the chamber 113. The chamber 113 is purged with an inert gas before a substrate on which material is to be deposited in the end is inserted into the chamber 113. Consequently, it becomes possible to remove fluorine residues and particles effectively and makes effective adjustment of the CVD chamber 113 possible.
