Title: High frequency signal receiver
Inventor: MASUDA SHIGETO
IPC: H04N5/44
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To suppress mutual modulation interferences without decreasing an NF(noise factor) in a receiver suitably used for television broadcasting which converts a high frequency signal to an intermediate frequency signal of a desired frequency. SOLUTION: The device 21 is provided with trap filters Faa to FMc which have center frequencies fa to fc respectively that correspond to an interference signal, such as an FM band, a VHF low channel band and a VHF high channel band. The device 21 selectively connects these filters to a high frequency signal stage with a switchign circuit 23 in response to a band switch of a phase-locked loop(PLL) circuit 28 and also connects an LPF 24 that can change a cutoff frequency to the high frequency signal stage by using a turning voltage VT from the circuit 28 to a local oscillator circuit 29. Thus, it is possible to suppress the entry of components of bands higher or lower than the band of a tuning channel into a mixer 27 and to prevent distortions due to mutual modulation interferences from occurring.

IPC: B23K35/30
Filed: 1979-04-09
Abstract: PURPOSE: To prevent the occurrence of cracking in weld metal by welding the underlayer of welding in such a manner that the carbon content in the weld metal becomes less than the specific amount and welding an upper layer thereon in build- up welding of iron, steel or cast iron of the specific carbon contents.  
     CONSTITUTION: A groove 2 is formed in the damaged portion produced in the base metal 1 of iron, steel or cast iron of 1.3wt% or more and 2.4wt% or less in carbon content. Thence, the base metal is build-up-welded with the underlayer 3 of build- up welding by using an automatic welding machine and mild steel or low-alloy steel welding material in such a manner that the carbon content in its weld metal becomes 0.7wt% or less. Thence, the upper layer 4 of build-up welding composed of the specific composition is build-up welded on the underlayer 3 of build-up welding. These obviate the occurrence of cracking in the weld metal even if the build-up welding is done automatically on the rolling roller or adamite roll roller of high carbon contents.

Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To integrate hole device into a LSI by displaying picture element data without a sense of incongruity consisting of the number of picture elements less than those of a LCD panel without using frame memory. SOLUTION: A control circuit 6 sends to a multiplexer 2 a selection signal SEL for selecting picture signal from an A/D converter 1 or a black data outputted from a control circuit 6. The selection signal SEL is determined according to a specification of a picture data inputted to a liquid crystal display device. For example, LCD 3 does not need to display block data when displaying a picture data to XGA specifications. When a picture data to VGA specifications is displayed, LCD is composed of an effective data consisting of 640×480 picture elements and empty spaces of up and bottom and right and left of the effective data, and picture elements are left over, and the black data are displayed by the remaining picture elements for a display without a sense of incongruity. A large scale of frame memory is not required for integrating into LSI.

IPC: E01C13/00
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To make it difficult to generate an irregular bound of a ball by installing a cloth between a pavement structure layer and a ground layer. SOLUTION: A base 3 is laminated on a ground (subgrade) 1, and a binder course and a surface course 4 are laminated thereon. A cloth 2 is installed between the ground 1 and the base 3. The cloth 2 is installed to prevent the mixture of fine earth granules, and the coefficient of permeability in the perpendicular direction to the surface of the cloth measured in accordance with JIS-A-1218 is preferably >=1×10<3> cm/sec. Even when the binder course and the surface course 4 are cracked and rain penetrates into the base 3 and the subgrade, weakened subgrade earth is mixed with crushed stone and crusher run of the base 3 to prevent the acceleration of differential settlement. Also, by suppressing the differential settlement, the court surface of a tennis court can be maintained in an approximately smooth condition.  Thus, the surface of the tennis court difficult to make an irregular bound can be maintained for a long time.

Title: Device for increasing pitching moment of aircraft
Inventor: ABE SHIGEKI
IPC: B64C9/02
Filed: 1994-03-15
Abstract: PURPOSE:To keep the position of an airframe by providing at the nose of the aircraft a movable control board which is longitudinally movable and which when in a forwardly projected position generates pitching moments in a direction for lifting the nose. CONSTITUTION:During normal flight, an aircraft flies with a movable control board 2 put in a nose part 1 by an actuator 4. During a takeoff and landing at which pitching moments are generated in a direction for lowering the nose, the movable control board 2 is moved onto a rail 3 by the actuator 4 and projected diagonally upwards. At this projected position the movable control board 2 generates vortices 5 even with a small elevation angle of the takeoff or landing, thereby generating pitching moments in a direction for lifting the nose, Therefore, the pitching moments which are generated in a nose-lowering direction as when landing gear and flaps are lowered can be canceled out.
