Title: Parallel plane slot antenna
Inventor: ANDO MAKOTO
IPC: H01Q21/24
Filed: 1991-07-12
Abstract: PURPOSE:To provide the parallel plane slot antenna which can obtain high gain with simple structure and further operates based on advancing waves. CONSTITUTION:This is a slot array antenna constituted on a parallel plane waveguide 3. A rectangular waveguide 6 for feeding is fitted under the center of the parallel plane waveguide 3. A radiating element to the outside and a feeding element to the parallel plane waveguide are composed of two pairs 5 and 7 of two slots, and the length and the space are optimized so as to suppress the reflection of the elements. A dielectric 8 is charged in the waveguide 6 for feeding as well so that only the fundamental mode can be propagated into the parallel plane waveguide 3. The slot pair 5 for radiation is vertically arranged close to the propagating direction so as to suppress a high-order mode generated in the parallel plane waveguide 3 by the radiation to the outside. By propagating radio waves in the right, left, upper and lower directions of the parallel plane waveguide 3, two polarized waves can be propagated.

Abstract: PURPOSE:To confirm the received data on a printer device side by printing and outputting external data as a character with a hexadecimal number by an operation of the printer device side as necessary in addition to a function for executing the printing in accordance with the received data. CONSTITUTION:In the case of a second operation mode, in a switch 1, '1' and '2' are brought into contact with each other, and an operation mode F/F a is '1'. When received data is written, a synchronizm control F/F 8 becomes '1', and becomes a write inhibiting state. A data selecting F/F 7 is '0', a nega tive logical output L is connected to a first data selecting circuit 4, and the circuit 4 selects the high-order 4 bits of a received data storage register 3, and outputs them to a data converting circuit 5. The circuit 5 generates the corresponding character code, when the data of 4 bits becomes hexadecimal, and outputs it to a second data selecting circuit 6. The circuit 6 outputs it as reception data 2. In the case of reading out the data 2, the F/F 7 is inverted by a signal and becomes '1', and outputs a negative logical output '0'. On the other hand, a mode signal is '1' and does not pass through an OR gate 9, and the synchronism control F/F 8 is not reset. In this state, the F/F 7 becomes '1', and the circuit 4 selects the low-order 4 bits of the register 3.

Filed: 1990-06-29
Abstract: PURPOSE:To prevent the generation of bending due to the plastic deformation free from the deterioration of the elastic limit in the vicinity of a welded part by welding a metal strand including the welded part and the contiguous metal strand at plural positions through laser spot welding, at least on a soft flexible pipe between the soft and hard flexible pipes. CONSTITUTION:A soft flexible pipe 1 is connected with a hard flexible pipe 2 and each joint part edge surface of both flexible pipes 1 and 2 is formed into a plane form, and a fused part 3 is formed on the outer periphery of the joint part through laser welding, and the soft and hard flexible pipes 1 and 2 are formed integrally. Laser spot welding is carried out at four points on the periphery from the outer periphery two times under shifting position, on the strand of the soft flexible pipe 1 positioned at the thermal influence part 4 of the slashed line part where the mechanical strength and elastic limit are deteriorated by the heat in the laser welding. Thus, a spot welding part 5 is formed, and a hard part 6 is formed through the rigid conversion of the thermal influence part 4. Accordingly, since the thermal influence part 4 due to the laser welding for the flexible pipe is formed into the hard part 6 through spot welding, the generation of the bending in the vicinity of the welded part through plastic deformation is prevented even in the bending with high strength.

Filed: 1989-07-04
Abstract: PURPOSE:To obtain a light-resistant transfer sheet whose transfer layer generates no fading or discoloration after transfer by mixing a hexagonal system ZnO fine powder into the inside surface of the transfer layer in contact with a base material. CONSTITUTION:A transfer sheet is a light-resistance transfer sheet wherein a transfer layer is formed to the single surface of a base material and a hexagonal system ZnO fine powder is mixed into the inside surface of the transfer layer in contact with the base material. As the base material, a polyester film, a polypropylene film, other various plastic films a metal foil, paper or cellophane can be used. The hexagonal system ZnO fine powder is a fine powder having a particle size of 400Angstrom  or less. When the particle size exceeds 400Angstrom , turbidity is generated and transparency is lost. As the hexagonal system ZnO fine powder, one having purity of 96% or more is used. When purity is not 96% or more, turbidity is occasionally generated. The hexagonal system ZnO fine powder is mixed into the resin of a release layer in a wt. ratio of 1 : 1 -0.1. When the amount of the hexagonal system ZnO fine powder is more than that of the resin, turbidity is generated and transparency is lost and, when the amount of said fine powder is less than 1/10 the resin, no sufficient light fastness is obtained.

Filed: 1982-10-01
Abstract: PURPOSE:To extend the dynamic range by using a quadratic function obtained by tow integrators so as to form an A/D converter having a root characteristic. CONSTITUTION:When a switch 2 is connected to the position (a) and a switch 6 is turned off, an analog signal applied to a terminal 1 is integrated for an optional time between time t1 and t2 by the 1st integrator 3. When the switch 2 is connected to the position (b) at the time t2 and the switch 6 is turned on, an output of a reference constant voltage generator 7 is integrated by the 2nd integrator 5 and applied to the 1st integrator 3 via the switch 2. Then, the output of the 1st integrator 3 approaches 0V in the form of a quadratic function from a voltage value at the time t2, and the time from the time t2 to the time t3 is proportional to the root of an analog input signal voltage, where t3 is the time reaching 0V. Thus, the number of clock pulses from the time t2 to t3 (digital signal) expresses a root of the analog input signal voltage.
