Title: Level gauge
Inventor: YASUDA HAJIME
IPC: G01F23/26
Filed: 1980-06-09
Abstract: PURPOSE:To measure a liquid level accurately by converting the electrostatic capacity that changes with the liquid level in a liquid tank into a frequency signal and measuring this frequency signal. CONSTITUTION:Electrodes A, B, C installed in a liquid tank are connected with vibrators Fa, Fb. The output frequency fa, fb are inputted to counters 4a, 4b to which clock pulse from a clock pulse generator 5 is inputted by lines a, b consisting of a shielding wire L1 through a selector circuit 1 and connecting circuit 3, and the frequency is measured. The electrodes C, D are always in contact with the liquid, and the electrostatic capacity between electrodes A, C changes with the change of liquid level. Therefore, fb is constant and fa changes with the liquid level. Accordingly, the liquid level can be obtained irrespective of kind of liquid by operating the frequency of the vibrators Fa, Fb when there is no liquid stored in the storage circuit 7 and the frequency measured by counters 4a, 4b in a comparing and operating circuit 6.

Abstract: PURPOSE:To improve a function with the simple constitution of a circuit by providing a shift register for storing command data in a range-finding device, performing range-finding corresponding to a command code at a specified bit position of the shift register and performing range-finding arithmetic operation by a microcomputer. CONSTITUTION:A serial I/O port 28 converts the parallel command data from the microcomputer 14 into serial data, which is stored at the specified bit of the shift register. Then, the range-finding is performed in accordance with the content of the stored command code and the range-finding arithmetic operation is performed by the microcomputer 14 based on the range-finding data so as to calculate a range-finding signal corresponding to a distance to an object. Thus, the range-finding device is controlled just by changing the command from the microcomputer, thereby improving the function with the simple constitution of the circuit.

Title: Motional perception controller
Inventor: NAKAMURA SHINJI
IPC: G06T19/00
Filed: 1996-04-02
Abstract: PROBLEM TO BE SOLVED: To increase a speed feeling and to prevent simulator sickness. SOLUTION: A driver sees videos which are different in the left and right to be presented on a rear projection screen 3 wearing polarizing spectacles which are different in the left and right. Consequently, the driver can see a three-dimensional video. Picture patterns for control are added to the videos in addition to the flowing visual fields acompanying the driving. That is, picture patterns minutely moving in the reversal direction with respect to the movement of the flowing visual fields or picture patterns minutely moving in the same direction in synchronization with the movement are added to the videos. Then, the speed feeling is increased by adding the picture patterns of the reversal direction and the simulation shickness is prevented by adding the picture patterns of the same direction.  Moreover, the same effects can be obtained by adding stationary picture patterns before or rear of the flowing visual fields.

Title: Joining method for metal
Inventor: KAWAGUCHI SEIICHI
IPC: B23K20/00
Filed: 1987-04-01
Abstract: PURPOSE:To eliminate the need for the necessary energy in melting and the heat treatment after welding by joining the joining face of a metal by pressurizing it in a liquid Na of limited temp. CONSTITUTION:The joining is effected by abutting joining faces so that the gap G on the beveling face of a steel stock 1 may become zero, inputting in the bath 3 in which the liquid Na of about 200-700 deg.C is contained and exerting the pressurizing force 4 of about 3-10kg/cm<2>. At this time, a good joining is obtainable by adequately changing the temp., heating time and pressure of the liquid Na according to the plate thickness, material, shape, etc. The liquid Na can activate the metal surface, clean the joining surface, diminish the distance among metal elements and make the joining easy, but the diffusion is delayed less than 200 deg.C to reduce the joining. Since the material is transformed at more than 700 deg.C 200-700 deg.C are appropriate. The pressurizing force is to be 3-10kg/cm<2> as the adequate range.
