Title: Water level measuring device
Inventor: SUZUKI TSUNEO
IPC: G01F23/28
Filed: 1993-06-17
Abstract: PURPOSE:To provide a water level measuring device measuring the water level of a river or the like via image processing, not required to be installed in the stream of the river, simple to install and maintain, and not broken at the time of a heavy rain. CONSTITUTION:The same water surface is photographed from different directions by the first and second television cameras arranged on a straight line at the uniform distance from the water surface to be measured. A field angle difference is generated between the image pickup patterns of the first and second images by the water level of the water surface, thus the water level is calculated. Feature points (waves or a floating object) on the water surface are acquired by a correlator to extract the field angle difference between the first and second images.

Abstract: PURPOSE:To cause needles to easily get out from a print ribbon even if they penetrate through it by fixing a cover plate having through holes slightly larger than a needle to the front surface of a needle guide and by setting the return positions of needles at such positions as located slightly inward from the front surface of the cover plate. CONSTITUTION:Of needle guides 3-9 which hold plural needles 2 so as to cause them to freely slide therein, the guide 3 which is positioned to oppose a platen is fixed, at its front surface, with a cover plate 11 having through holes 10 for causing needles 2 to pass through. The needle 2 is driven by an electromagnet 15 and its return position is determined by a stopper 20, but it is arranged so that the end of the needle 2 comes between the front surface of the guide 3 and that of the cover plate 11 at its return position. By this arrangement, the needle 2 easily gets out from a print ribbon in the latter half of its return motion even if it penetrates through the ribbon at the time of printing and the needle 2 is prevented from being bent or broken. The needle 2 is also prevented from being caught by the guide 3.

Title: Fuel leakage preventer for automobile
Inventor: TSUBOI MASARU
IPC: F02M37/00
Filed: 1988-07-08
Abstract: PURPOSE:To prevent fuel from leaking to the outside of a fuel tank with certainty by forming each fuel sump chamber interconnected via a vapor outlet, in the upper part of a float chamber, while installing an emission passage in an upper part of the fuel sump chamber in a combined manner. CONSTITUTION:A first fuel sump chamber 26a is formed in the upper part of a float chamber 22 by an upper wall of a casing 21a and another casing 21b, interconnecting it to the float chamber 22 via a vapor outlet 25. This first fuel sump chamber 26a is interconnected to a second fuel sump chamber 26b via a clearance 28. An emission passage 29 is interconnected to an upper part of the second fuel sump chamber 26b. When a fuel level goes up so suddenly and thereby fuel flows out to the outside of the float chamber 22 by way of the vapor outlet 25, it is once stored in a fuel sump chamber 26, whereby this fuel will not flow into the emission passage 29 installed in the upper part. When the fuel level in a fuel tank 50 is lowered, the stored fuel goes back to the float chamber 22 from the vapor outlet 25.

Abstract: PURPOSE:To efficiently obtain dried grains reduced in the occurrence of the cracking and having a good taste by a method wherein, in a storage tank, is provided a far infrared radiation chamber which downwardly applies jets of far infrared radiation heat and hot air to the grains flowing downwardly along air drying parts and a feeding part. CONSTITUTION:In a longitudinally long and laterally wide tubular dryer body 1, a storage tank 2, the air drying parts 8 arranged laterally or longitudinally in a plurality of rows, a feeding part 3 and a removing tank are disposed from the upper to the lower part of the dryer body in communication with one another. In the storage tank is provided a far infrared radiation chamber 5 which downwardly applies the jets of far infrared radiation heat and hot air to the grains flowing downwardly along the air drying parts 8 and the feeding part 3. In this way the grains can be dried without any excessive effort in a short time while maintaining a balance between the rate of the dissipation of water from the grain surface and that of the dispersion of water from the interior to the surface of the grain and without causing the occurrence of the cracking or an uneven downward flow of the grain, whereby the dried grain having a good taste can be obtained.

Title: In-island money-changing machine
Inventor: TAGUCHI KAZUYA
IPC: G07D1/04
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To make a money-changing machine compact, arranged between amusement machines by driving a coin carrying means only when a request signal is outputted from a money-changing coin hopper and carrying coins of a specific money sort from the way of a coin recovery passage to the hopper. SOLUTION: When a coin detection means 31 arranged on the lower side of a coin hopper 27 can not detect 500-yen coins, a control device 30 closes a large diameter coin recovery port, starts a coin carrying device 18 and outputs a control signal for carrying 500-yen coins to the hopper 27. When a coin detection means 32 arranged on an upper stage of the hopper 27 detects a state full of 500-yen coins, the device 30 opens the large diameter coin recovery port, stops the drive of the device 18 and outputs a control signal for recovering 500-yen coins to a large diameter coin recovery safe. Since 500-yen coins charged into ball lending machines arranged on both the sides of the money-changing machine are recovered and used for 500-yen coins to be discharged as coins changed from paper money, the size of a safe for storing 500-yen coins can be compacted.

Title: Method for annealing steel strip coil in batch annealing furnace
Inventor: YASUFUKU MASAO
IPC: C21D9/663
Filed: 1992-06-30
Abstract: PURPOSE:To prevent the occurrence of quality defects, such as edge wave, by disposing an object with large heat capacity between a steel strip coil and the ceiling of an inner case. CONSTITUTION:A steel strip coil 2 placed into up-end state on a base plate 3 is covered with an inner case 5 and annealing is done in this state. At this time, an object 1 having high heat capacity as compared with the inner case 5 is disposed between the top of the steel strip coil 2 and the ceiling of the inner case 5. By this method, the occurrence of defects, such as edge wave, in the coil 2 can be prevented because the rapid cooling and rapid heating of the coil 2 can be prevented while the heat stored by the object 1 is released even when the inner case 5 is rapidly cooled or rapidly heated. It is preferable to use the object where, when Q represents the thermal capacity of the object with high thermal capacity and A represents the area of the top of the coil 2, Q is regulated to 1.72X10<-5>A to 5.16X10<-4>A(Kcal/ deg.C).

IPC: H01L21/205
Filed: 1985-08-06
Abstract: PURPOSE:To produce an amorphous semiconductor with a wide band gap and an excellent photoconductivity by making nitrogen co-existent with carbon. CONSTITUTION:Within an amorphous semiconductor composed of nitrogen co-existent with carbon, preferable composition is 100 silicon atoms containing 5-30 atoms of hydrogen and/or fluorine, 5-30 atoms of nitrogen and 1-20 atoms of carbon. Because it increases the density of defects and decreases the photoconductivity for silicon to contain carbon, the content of carbon in silicon is recommended not to exceed 20 atoms to 100 silicon atoms while in order to improve the P-type valence electron controllability, the content of carbon in silicon is recommended to exceed 1 carbon atom. Besides, nitrogen atoms coupling with silicon atoms at 3 coordination to soften a network structure is recommended to exceed 5 nitrogen atoms to 100 silicon atoms also not to exceed 30 nitrogen atoms since band gas exceeds 2.5eV decreasing the photoconductivity.
