Title: Printer
Inventor: HAGA YOICHI
IPC: B41K3/10
Filed: 1984-10-01
Abstract: PURPOSE:To enable to print at a multiplicity of digit places without need for closely aligning types even where a printing area is narrow, by moving types toward and away from a printing area while reciprocating them in the width direction of the printing area of a body to be printed. CONSTITUTION:A printer for printing an index of the kind of product on a CRT or the like is provided with a plurality of, for example, two type wheels 7, 8, type-selecting mechanisms 9, 10 and a type wheel driving mechanism 5, the type wheels 7, 8 being provided with a plurality of types 50 at outer peripheral surfaces thereof and being spaced from each other. The mechanisms 9, 10 rotate the type wheels 7, 8 indenpendently to select types 50. The mechanisms 5 reciprocates the type wheels 7, 8 in the width direction of the printing area 4 on the body to be printed, and move the type wheels toward and away from the printing area 4, thereby printing at a multiplicity of digit places. Accordingly, printing at multiple digit places can be conducted without need for closely aligning the types even where the printing area of the body to be printed is narrow, and since the type wheels are moved in the width direction of the printing area, spacing in printing can be arbitrarily set.

Title: Address translation circuit, memory controller, information processor, and recorder
Inventor: IZEKI TOSHIYUKI
IPC: G11C8/00
Filed: 1989-08-09
Abstract: PURPOSE:To control the DRAM of different capacity and to reduce the number of multiplexers of an address bus by alternately multiplexing two adjacent bits of an address to be translated as one pair, and outputting it. CONSTITUTION:At an information processor or a recorder, a memory controller 4 alternately outputs a conversion address, which alternately multiplexed two adjacent bits of consecutive addresses as one pair by an address translation circuit 56, as a row address and a column address, and accesses the DRAM 6. That is, the multiplexer of the address translation circuit 56 multiplexes adjacent addresses, and, for example, selects the address of an odd number bit when outputting the row address, and selects the address of an even number bit when outputting the column address. Thus, when connecting the DRAM 6 of various capacity, the number of multiplexers of the address bus is made smaller, the scale of the memory controller is made smaller, and because of this, the delay time can be reduced.

Title: Stealth antenna system
Inventor: ORIME SHINKEI
IPC: H01Q15/22
Filed: 1984-10-03
Abstract: PURPOSE:To minimize the radar cross section by arranging a metallic plate having a polarized wave selectivity or a frequency selectivity to a front face of a slot antenna or a parabolic antenna opposite to an aperture obliquely. CONSTITUTION:Since the metallic plate 10 with slots fitted with a tilt of theta1 to a mechanical antenna 2 is so designed that only a polarized wave and a frequency of a radio wave irradiated from the antenna 2 are transmitted, the radio wave transmits through the metallic plate 10 and propagates in a direction of a straight line RQ. Then a stealth antenna 12 receives a radio wave having the same polarized wave as that of a radio wave from the antenna 2 and propagating toward the straight line QR among radio waves reflected on a radar site of an enemy and the radar site of the enemy is tracked through signal processing. Further, a radio wave irradiated from the radar site of the enemy 6 goes straight toward the QR and reaches the metallic plate 10, but since the metallic plate 10 acts like a conventional metallic plate for a frequency other than that of the own radar, the radio wave is reflected on the surface.
