Title: Power amplifier circuit
Inventor: FURUYA OSAHISA
IPC: H01P5/02
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To provide a technology by which a power amplifier circuit with a high efficiency is designed without notifying a matching circuit, the design is facilitated and the development cost is reduced. SOLUTION: A 1st series resonance circuit 18 is connected between the output electrode of an amplifier element 12 and the input terminal of an output side matching circuit 15, a 2nd series resonance circuit 19 is connected between ground and the input terminal of the output side matching circuit 15, and the resonance frequencies of the 1st and 2nd series resonance circuits 18, 19 are in matching with a 2nd harmonic wave of a high frequency signal appearing at the output electrode of the amplifier element 12. The impedance (short-circuit) of the output electrode of the amplifier element 12 with respect to the 2nd harmonic wave is obtained by only the resonance action of the 2nd series resonance circuit 19. Since the effect of the impedance of the output side matching circuit 15 is not entirely received, the design is simplified and the development cost is reduced.

Title: Method for forming embossed sheet
Inventor: KONO KATSUTOSHI
IPC: B29C48/305
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To score accurately efficiently embossment of an embossed sheet by heating a sheet surface to a secondary shaping side when shaping by rolling is carried out with an embossed roll after melt extrusion of thermoplastic resin from a T-die. SOLUTION: An embossed roll is arranged to an under roll 4 or an intermediate roll 5 and an upper roll. That is, primary shaping is carried out with the under roll 4 or the intermediate roll and secondary shaping is carried out with the upper roll. However, since enough contact time with the roll can be taken, the embossed roll is preferably arranged at the intermediate roll and the upper roll. When a sheet is secondarily shaped, a far-infrared radiation heater 9 is installed as a heating means for a sheet surface. At that time, in order to heat effectively the sheet surface to be secondarily shaped, a recessed surface is so arranged to be constituted along the intermediate roll 5, and it is preferably arranged to be further near to the intermediate roller 5.

Abstract: PURPOSE:To improve the reliability of the document processor by forming the peripheral distribution of a graphic expressing a sentence tree structure from the upper layer to the lower layer of the graphic and successively referring the distribution to detect the position of an image area corresponding to the graphic. CONSTITUTION:An instructing means 14 outputs the position control signal and a dividing element sort of a mark M. an information forming means 16 forms structure information based upon dividing instruction information to control the display of a display means 12 and displays the initial graphic on a display screen 12. The means 14 is operated in order to regenerate the relative positional relation between the dividing elements of a document 32 on the initial graphic. Since a space 34 is a dividing element extended in the horizontal direction to divide the initial graphic, the mark M on the means 12 is moved to one side of the initial graphic by operating the means 14. At the time of inputting the dividing instruction information, the means 16 obtains the sort, position and extending direction of the dividing element. Consequently, a block position can be rapidly and highly accurately detected by the simple processing.
