Abstract: PROBLEM TO BE SOLVED: To separately measure spectrums having near wavelengths. SOLUTION: An incident optical axis of the light into a diffraction lattice 34 is made different from a diffracted optical axis, and a resonator is formed both by the optical path from a first half mirror 33 for letting the light to be measured enter to the diffraction lattice 34 and by the optical path from the diffraction lattice 34 to a second half mirror 38, and the light transmitted through the second half mirror 38 is incident on a light receiver 40 through a condenser 39.

Title: Controller for fuel of engine
Inventor: TOMINAGA KAZUNORI
IPC: F02D41/12
Filed: 1983-08-20
Abstract: PURPOSE:To prevent the stall of an engine, which is likely to occur when the position of an automatic transmission is shifted, by providing a means for eliminating a fuel stoppage signal generated in the deceleration of the engine, when the automatic transmission is shifted from the neutral position to a drive position. CONSTITUTION:In the deceleration of an engine after its racing, an H-signal indicating a fuel cutoff region is supplied from a gate 7 to another gate 9. When a gearshift is changed from the neutral range to a drive range, an L-signal having replaced the H-signal is supplied as a shifted position signal to a timer 6 so that the timer sends out an H-signal for ceasing the stoppage of fuel, to the gate 9 for two seconds since the L-signal is supplied as the shifted position signal. For that reason, an L-signal for supplying fuel is sent from the gate 9 to another gate 10 for the two seconds so that the gate 10 sends an H-signal to a transistor 11. As a result, an injector 5 injects the fuel for the two seconds though the operation of the engine is in the fuel cutoff zone, thus preventing the engine from stalling.

Filed: 1996-06-13
Abstract: PROBLEM TO BE SOLVED: To extend the transmission distance in the case of 2-way video communication by eliminating adverse effect due to a beat stripe caused when a frequency of an FM carrier is selected lower. SOLUTION: A video signal picked up by a camera 43 of a slave set 40 is frequency-modulated by an FM carrier to obtain a video FM signal. In the case of applying frequency modulation to the video signal, the phase of an FM carrier is reset by an external synchronizing signal S to synchronize the video signal with the FM carrier. The video FM signal is sent to a master set 41 and the demodulated video image is displayed on a monitor 55. Since the video signal and the FM carrier has a correlation, even when the FM carrier is leaked and a beat stripe takes place on the screen of the monitor 55, a still state of the image is obtained.

The register group 1 registers values specifying respective segments obtained by dividing the main memory correspondingly to the plural communication control devices and the contents of the register group 1 are interrupted or read out by the outputs of the circuit 4. Buffers 5, 6 controls data at the time of writing/reading out data in/from the register group 1. Consequently the main memory can be segmented and DMA corresponding to respective communication lines can be attained.

Abstract: PURPOSE:To reduce damage for a tape and to enable satisfactory recording and reproducing by providing a recessed part, which rotary shaft and length in a peripheral direction are shorter than those of a rotary drum, near a window part on the outer peripheral and cylindrical face of the rotary drum. CONSTITUTION:A rotary drum 2 is freely rotatably supported through the shaft to a fixed drum 1, and at a window part 8 provided on the outer peripheral and cylindrical face of the drum 2, a head 3 is arranged while being protruded for a prescribed amount from the outer peripheral and cylindrical face of the drum 2. A recessed part 9 is provided near the window part 8 on the outer peripheral and cylindrical face of the drum 2 over a phase advanced from the same phase as the head 3 at a rotary phase.
