Filed: 1989-02-17
Abstract: PURPOSE:To prevent the increase of the number of ICs of a decoder circuit and to reduce the capacity of a ROM for the reduction of a switch information processing time by connecting the input signal of the decoder circuit which selects a common signal of a switch to an address signal received from a CPU, and selecting one of common signal lines with a program input instruction. CONSTITUTION:The input signal of a decoder circuit 14 which selects a common signal of a switch 11 is connected to an address signal received from a CPU 1, and the switch information is fetched into an I/O port with only a program input instruction. Thus, it is possible to prevent the increase of the number of outputs of an I/O port 12 as well as the number of ICs of the circuit 14 that are conventionally caused by the increase of the number of switches of such a kind of circuit. Furthermore, the capacity of a ROM can be reduced and the switch information processing time is shortened.

Filed: 1994-02-10
Abstract: PURPOSE:To obtain a stable characteristic with a simple structure without generating a noise in a low attenuation amount by connecting the waveguide on the input side to the waveguide on the output side shifting their core axes in the connection part of the waveguide. CONSTITUTION:A waveguide is an optical fiber 1, the core axes 3 of a waveguide on the input side and a waveguide on the output side are connected in the misaligned state 4 in a connecting part and they have also a waveguide longer than 10cm toward the optical output side from the connecting part. As to a manufacturing method for obtaining these conditions, the optical fibers 1 are fixed and connected while the core axes are misaligned after the fiber 1 are cut off. As the connecting means, connection by electric discharge machining is easy and the thermal expansion coefficient of the stuck part is made equal to that of the optical fiber. In order to obtain an optical attenuator having a target attenuation ratio, the amount of shift of the core axes 3 of two optical fibers 1 is adjusted and the fibers are connected by such amount of shift that the optical output becomes a prescribed value while a light beam is inputted from a light incident side and the beam from the output side is monitored by an optical power meter. Consequently, a stable characteristic is obtained even in the low attenuation amount.

Filed: 1985-02-27
Abstract: PURPOSE:To quicken the speed of dispersion and propagation of lead fluid and detect leak quickly by providing a double wall heat transfer tube with lattice type detecting grooves on the boundary between double walls. CONSTITUTION:The lattice type detecting grooves 20 are provided on the inner surface of outer tube 11 of double wall heat transfer tube 12.

Title: Differentiation circuit and clock generating circuit using it
Inventor: TANAKA KAZUO
IPC: H03M5/06
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To generate a high purity clock signal by eliminating undesired frequency components from a clock signal. SOLUTION: A delay circuit 12 delays an inverse S2b of a non return to zero NRZ data signal S1 by a 1/2 of a data latch period To of the NRZ data signal, the delayed signal S2b is added to a noninverting NRZ data signal S2a at a node Na to generate a differentiation signal S3a. The differentiation signal is full-wave-rectified by a nonlinear circuit 21, from which a rectified signal S7a is produced, The rectified signal S9a is given to a resonator 31 whose resonance frequency is fCLK with respect to the period T0 , from which a clock signal S9a with the frequency fCLK is generated. In this case, resonance with a frequency in the vicinity of the frequency fCLK is caused in the delay circuit 12 due to impedance mismatching and dispersion in delay times.  The resonance component is mixed in the differentiation signal S3a and passes through the nonlinear circuit 21 and the resonator 31, but the resonance component is eliminated by providing a low pass filter LPF 14 to a pre-stage of the nonlinear circuit 21.

Abstract: PROBLEM TO BE SOLVED: To reduce the amount of a reducing agent flowing out from an exhaust gas purifying catalyst as NOX is excellently purified. SOLUTION: An exhaust gas purifying catalyst 19 is arranged in an engine exhaust passage. Secondary fuel is injected from a fuel injection valve 11, a reducing agent is fed to the exhaust gas purifying catalyst 19 to reduce NOX.
