Title: Fence of elevated bridge
Inventor: SHISHIDO TOSHIO
IPC: H05K9/00
Filed: 1988-07-14
Abstract: PURPOSE:To securely and cheaply prevent interference of a radio wave by a method wherein the radio wave is positively reflected to a direction different from that of a receiving antenna. CONSTITUTION:When a panel 4 is built on a side beam 1a of an elevated bridge 1, the panel 4 is bent on a standing portion from the side beam 1a and a portion upper the bent portion 4a is tilted toward inside as a straight portion 4b which extends from the bent portion 4a. The panel 4 of this kind is stood along the side beam 1a at appropriate intervals, and a panel 5 made of metal is extended between the columns. A radio wave 3 transmitted from a TV station or a relay station proceeds in an approximately horizontal direction and is reflected by the panel 4a of a fence 4, so that the directivity range of reflected waves of the radio wave 3 is raised, with almost no reflected waves entering the antenna left. This can securely and cheaply prevent radio wave interference.

Title: Analog signal transmission equipment
Inventor: NAKABAYASHI TAKASHI
IPC: H04B10/2543
Filed: 1995-07-12
Abstract: PROBLEM TO BE SOLVED: To provide analog signal transmission equipment with which transmission quality is improved by shortening the oscillated wavelength of a DFB (distributed feedback tupe) laser rather than the zero distributed wavelength of an optical fiber for guiding emitted light. SOLUTION: An original analog signal is converted to a light intensity signal and outputted as an optical signal by a DFB laser 110 of a transmitter 100. In the case of this electric/optic conversion, distortion D1 is generated inside the DFB laser 110. The optical signal outputted from the transmitter 100 is inputted to an optical fiber 200 and propagated inside the optical fiber 200. In the case of this propagation, distortion D2 is generated inside the optical fiber 200. The optical signal outputted from the optical fiber 200 is inputted to a light receiving element 310 of a receiver 300 and converted to an electric signal. Since the phase difference between the distortion D1 and D2 gets more than 90 deg. at least, the distortion D1 and D2 are canceled each other.

Title: Tester for heat generating element of thermal head
Inventor: FURUKAWA NOBUO
IPC: B41J2/275
Filed: 1986-07-26
Abstract: PURPOSE:To attain prevention of burning of driving ICs and a shorter resting time, by supplying a fixed current to a heat generating element, and calculating the resistance of the element from the relationship between the fixed current and a voltage drop across the element. CONSTITUTION:A printing voltage P.V is set by a programmable power source 11 so that a current in a current-checking mode is I1, and a heat generating element R1 is first energized. During energization of the element R1, the voltage P.V is held by a sample holder 12, and the held value is subjected to A/D conversion by an A/D converter 13. A microcomputer 14 subtracts a voltage drop through a driver circuit from the result of conversion to calculate a voltage drop V1 across the element R1, then calculates the resistance of the element R1 from the relationship between the voltage drop V1 and the fixed current I1, and discriminate the calculated value. This operation is repeated for the heat generating elements R1-Rn. Since the fixed current is supplied to the heat generating elements, the voltage drop in the driver circuit 9 is constant irrespective of the resistance of the element being tested, and it is sufficient to measure once the constant voltage drop under the fixed current I1. Thus, a shorter testing time can be attained. In addition, since the fixed current is not changed even when the heat generating element is short-circuited, it is possible to attain prevention of burning of driving ICs.

Filed: 1989-07-07
Abstract: PURPOSE:To suppress the diffusion of a sealing material in the inner and outer directions of a container by forming cut-out parts for suppressing the diffusion of the sealing material at the connecting part between a case and a cap. CONSTITUTION:A ceramic cap 6a covers a semiconductor pellet 5a. A cut-out part 11 having the wedge-shaped cross section is provided along the outer surface of the side wall of the cap from a connecting surface 9a between a case 1a and the cap 6a at the bottom part of a side-wall 10a of the cap 6a.

Title: Variable valve timing device of internal-combustion engine
Inventor: UMEHANA TOYOICHI
IPC: F01L1/34
Filed: 1984-08-27
Abstract: PURPOSE:To to make it possible to use a miniature and lightweight motor, by driving a step motor to control the velve timing, when a cam shaft is given a reaction force from a valve spring along the positie rotating direction. CONSTITUTION:Whether the number of steps is increased in order to advance the valve timing, or the number of steps is decreased in order to delay the valve timing, is decided by the first discriminative means 5 based on output signals from an intake air quantity sensor 2 and an engine speed sensor 3. And then, whether it is the crank time for that a cam shaft is given a reaction force from a valve spring along the positive rotating direction, or not, is decided by the second discriminative means 7 based on a signal output from a crank angle sensor 6. Pulse is fed so that a step motor 4 is driven by the number of steps output from the first discriminative means, at the time the cam shaft is given a reaction force along the positive rotating direction. As the step motor 4 is driven when the load is small, a miniature/lightweight motor is enough to use, and the consumption of electric power can be decreased.

Title: Data transmitter
Inventor: EMU JIEI GANSU
IPC: H04N7/00
Filed: 1991-06-21
Abstract: PURPOSE: To eliminate interference between simultaneously transmitted signals to obtain a high-definition picture by changing the transmission power of a second signal in accordance with the state of a first signal. CONSTITUTION: A TV signal is radiated through a TV modulator 100 and a horizontal deflecting antenna 108. A data signal is temporarily stored in a buffer 101 simultaneously with transmission of the TV signal and is next read out in order and is transmitted through a data modulator 105 and a vertical deflecting antenna 109. At this time, a busy detection circuit 106 monitors the TV signal and increases the output power of a data converter in the period of its busy part and reduces the transmission power of the data signal in the period of its idle part. Consequently, the larger transmission power of the data signal doesn't break the TV signal practically because the TV signal allows a large extent of interference in its busy part.
