Filed: 1990-04-07
Abstract: PURPOSE:To hold secrecy and to prevent forgery by providing a steres bar code, which is colorless and transparent in a visible light area, using an indium - stannum oxide or a stannum oxide on a substrate. CONSTITUTION:By attaching a thin film composed of the indium - stannum oxide or the stannum oxide onto a substrate 7 or coupling the powder of the indium - stannum oxide or of the stannum oxide onto the substrate 7 by coupling agent resin, a steres bar code 8 is provided to be completely colorless and transparent in the visible light area. When the substrate 7 of an ID card 6 to travel through a slit 3 and the steres bar code 8 are irradiated with infrared rays from a light emitting diode 1, the infrared rays irradiating the steres bar code 8 are reflected and the infrared rays irradiating the substrate 7 are transmitted and photodetected by a photodetector 2. Thus, the secrecy can be sufficiently held and the forgery can be prevented.

Title: Oscillator eqipped winth dielectric resonator whose frequeny is tuned electronically by varactor especially at about 22ghz
Inventor: ISAAKU METOUDEI
IPC: H03B5/18
Filed: 1988-04-14
Abstract: PURPOSE: To facilitate the adjustment of an oscillated frequency by arranging 1st and 2nd strip lines in a line, connecting an active element to its terminals, connecting a varactor diode to a 3rd strip line and connecting two dielectric resonators to the 1st strip line. CONSTITUTION: The gate and the drain of an active electronic element having a negative resistance such as a GaAs FET 17 are respectively connected to strip lines 10, 11. One terminal of a varactor diode 26 is connected to a terminal of a strip line 12, and the other terminal is grounded via a strip line 27 and a hole 25. A proper coupling is formed between the varactor 26 and the FET 17 in the dielectric resonator 40. Furthermore, the dielectric resonator 41 is useful to properly adjust an output frequency of an oscillator. By the use of the dielectric resonators 40, 41 the coupling function and a frequency adjustment function are separate to some extent, and the adjustment of the frequency can be executed flexibly and easily more than in the case using only one dielectric resonator.  The output frequency is increased/decreased without operating the resonator 40 by changing the height of the dielectric resonator 41.

Abstract: PURPOSE:To restrain indentation due to thermal contraction which is generated on the surface side of an automotive external rig in such a way that diameters of bosses which are protruded from the back side of an automotive external rig for fitting fixed parts are set up to be the determined value to the thickness of the external rig for automobile. CONSTITUTION:A fixed part 21 to be fitted to an automotive external rig 20 is assembled by a bracket 22, and a bolt 24 which is inserted from the rear side into a hole 23 at the center of the bracket 22. Bosses 28, 29 which are protruded from thr external rig 20 are inserted into holes 26, 27 on the flat part 25 on the peripheral side of the bracket 22, and head parts 30 which have larger diameter than the holes 26, 27. The diameter of the bosses 28, 29 are set to less than two thirds the thick plate of the external rig 20. Since said bosses 28, 29 are set smaller in their diameter, fitting strength of the fixed part 21 is reduced, but the reduction of the fitting strength can be prevented by setting increased number of the bosses 28, 29.

Filed: 1992-03-19
Abstract: PURPOSE:To stop smoothly even when a motor vehicle goes down a steep slope by providing a rotation sensor, an r.p.m. detecting circuit, a CPU, and a drive/ reverse switching circuit. CONSTITUTION:Number of revolution and rotational direction (advancing direction) are inputted from a rotation sensor 14 through an r.p.m. detecting circuit 15.

Filed: 1980-07-09
Abstract: PURPOSE:Fossil fuels, alcohols and water are used as raw materials and subjected to a catalytic reaction under heating to activate the mixed gas, thus producing a novel type of combustible gases as a low-cost energy. CONSTITUTION:Fossil fuels, alcohols, water and air are combined in various ways and these combinations are passed through filter 1 and reaction is caused while they pass through catalyst 2 to form a feul gas, which passes through nozzle 4 and goes to the combustion process. Before the combustion process, the heat for activation is transferred from the reaction case 3 to the catalyst 2 and the spaces in the  catalyst 2 are filled with hot particles. The hot particles are released depending on  the reduction heat and the space is continuously filled with the hot particles until  they are ionized. Thus, the relative speed of the hot particles and the whirl friction cause the high-speed ractions. USE:Hydrogen gas and alcohol are obtained from water and fuels.
