Title: Video signal detecting circuit
Inventor: ISHIGURO MEGUMI
IPC: H04N5/44
Filed: 1985-04-01
Abstract: PURPOSE:To improve the discrimination accuracy by using a vertical scanning period except a vertical blanking section as a count time width to count a horizontal synchronizing pulse and discriminating the presence of an input video signal based on the count value. CONSTITUTION:A channel selection microcomputer 5 receives an output of an AFT detection circuit 6 detecting a carrier level of the output of an IF circuit 3 to introduce a control voltage to lock a PLL of a tuner circuit 2 to a tuning point. A horizontal synchronizing pulse (H pulse) is obtained by applying amplitude discrimination to a video output of a detection circuit 4 by a synchronous separator circuit 7 and given to a clock input CK of a pulse counter 8. A vertical synchronizing signal V is led to a V pulse forming circuit 9, and a V pulse whose level is low at the V blanking section is given to an enable input of the counter 8 from a gate circuit 10. The counter 8 counts the H pulse at the high V pulse level section, the computer 5 discriminates whether or not the count is within the permissible width and completes the channel selection when the count is within the permissible range.

Title: Vibration damping device
Inventor: ARIKI SHIGERU
IPC: E04H9/02
Filed: 1998-03-04
Abstract: PROBLEM TO BE SOLVED: To cope with large displacement, to reduce a cost and to prevent damage of an installed member by interposing a coil spring between mutually opposing two spring seats arranged on an expandable column. SOLUTION: Mutually opposing two spring seats 2, 3 are arranged in the intermediate part of an expandable column 1 so that a coil spring 4 of an easily plastically deformable single material is expandably interposed between the spring seats 2, 3. The column 1 is composed of an outer tube 5 and an inner tube 6 slidingly inserted into the outer tube 5. When vibration by an earthquake is generated in a structure, the outer tube 5 and the inner tube 6 mutually expand or contact. Therefore, the coil spring 4 joined to the spring seats 2, 3 also expands or contracts. At this tine, damping force by a bysteretic characteristic of absorbing vibration by converting vibrational energy into heat energy, is generated by deforming the coil spring 4 by plasticity.

Abstract: PURPOSE:To obtain the semiconductor device having a high humidity resistance by a method wherein a polymer comprising a repeating structural unit expressed by the specified general formulas is spread and is printed to form a protective coating on a surface of the semiconductor element which is sealed by use of a resin composition or ceramic after that. CONSTITUTION:The solution of a polymer comprising a repeating structural unit expressed by the general formulas ( I )-(III) (wherein R<1> and R<2> express the same or the different hydrocarbon radicals of one valency) is spread on surfaces of a semiconductor element 2, a lead wire 1 and so on. Next, a printing treatment is performed by heating with 100 deg.C or over, more preferably with 150- 300 deg.C. By this treatment, the polymer increases the molecular weight and crosslinking occurs to form a protective coating layer. The coating layer should be formed preferably so as to have a thickness of 10mum or less, more particularly of 1mum or less for obtaining good effects. This is attained by adjusting the concentration of the solution properly under 5wt% usually. Subsequently, the object composed of the element 2 and the lead wire 1 comprising a protective coating layer 3 is sealed, e.g. with an epoxy resin composition 6, thereby offering the semiconductor device.
