Title: Measuring method for moving speed and distance
Inventor: MITOME HIDETO
IPC: G01S5/18
Filed: 1980-09-10
Abstract: PURPOSE:To simplify measuring of a speed and a distance, by a method wherein a reference signal, received at a reference point by a moving object, is produced into a serial signal by means of a gate circuit, a delay element, and a feedback circuit, and a signal, received at a current spot by the moving object, is compared with a phase. CONSTITUTION:Sampling of a reference signal is conducted through the reception of a signal, such as ultrasonic waves, from the bottom of the sea in a capsule above the water. The signal is inputted to a gate circuit G and is controlled by a clock circuit to produce a signal a having a width DELTAt. The signal is inputted to a delay element d to provide a delay by the DELTAt again to produce a serial signal b. After said sampling is completed, the capsule starts to fall, a phase difference between a signal c, sent from the bottom of the sea and received at a current spot, and the signal b is found by means of a phase difference comparison circuit to find the speed of the capsule, and a phase difference is integrated to find a moving distance. This eliminates the need for an equipment, transmitting a reference signal from a mother ship, and as a result, permits the constitution of a simple device.

Title: Guidance device for running vehicle
Inventor: HOZUMI HISASHI
IPC: G05D1/02
Filed: 1980-09-10
Abstract: PURPOSE:To improve the safety of running by detecting the direction of the deviation of a running vehicle from a guidance body and by correcting the running direction. CONSTITUTION:During a normal run, a running vehicle moves forth so that a guidance line 1 is positioned near the centers of detection coils 6 and 6a. Namely, the difference signal of detection signals of both the detection coils is inputted to one terminal of a differential amplfier 15, and a signal from a potentiometer 17 detecting the rotation point of a steering motor 7 is inputted to the other terminal to drive the motor 7, so a steering wheel is set in a predetermined adequate direction to guide the running vehicle. When the running vehicle deviates from the guidance line 1, signal levels of the detection coils 6 and 6a lower. Those levels are detected by comparators 18 and 18a to detect the deviation direction according to which level lowers first, and then the running vehicle is returned to the original direction through a motor controlling circuit 16.

Abstract: PURPOSE: To realize light modulation by radiating light of which wavelength is shorter than the absorbing end to a crystal such as of semiconductor and insulator under the condition of constant applied voltage so as to change the absorbing end.  
     CONSTITUTION: An Fe doped π type GaAs 0.8 P 0.2  layer 1 is vapor-grown on an n-type GaP substrate 2, and transparent electrodes 3 of In 2 O 3  are formed on both sides thereof by sputtering. In such constitution, the side of the substrate 2 is regarded as side A, and the opposite side as side B. A bias voltage V which is positive on side A is applied, and light I from a monochromatic meter is caused to enter from side A. When its transmitted light I' is measured, as the bias voltage increases, its abosrbing end will move to longer wavelength side almost proportionally. Suppose the bias voltage is set to 18 volts, when a light II of which wavelength is shorter than the avsorbing end is applied, the absorbing end will further move to the longer wavelength side. That is, by changing the intensity of the radiation light, the light may be modulated

Abstract: PURPOSE:To obtain sufficient electron beam current intensity between electron guns and restrain divergence of an electron beam at the outermost end of each electron gun by making the form of the grid of one electron gun regarding the direction of the major axis nonsymmetrical, the electron guns being located at both ends. CONSTITUTION:The outside and inside portions of each filament 2a, 2b with respect to a center position line A extending in the direction of the major axis of an electron beam opening 21a are G11, G12, respectively, and each filament 2a, 2b is formed in a non-symmetrical way. In this case, G11<G12, and each filament 2a, 2b is so formed that each length G11,G12 and the length of each filament in the direction of its major axis are in such a relation to each other as to cause a grid to generate a flat area within the area of the length G11 outside the center position line A and generate a divergence area within the area of the length G12 inside the center position line A. An electron beam emitted from each filament 3a, 3b therefore diverges on the inside portion of each filament 2a, 2b but scarcely diverges on the outside portion.
