Abstract: PURPOSE:To enable a highly sensitive detection, by a method wherein the sediment which was obtained by neutralizing a tin tetrachloride aquaous solution by ammonia in the coexistence of ammonium nitrate is calcinated at 400-700 deg.C and then, molded into the shape of sensor element which is sintered by heat at 500-700 deg.C and changes in the electric resistance of the element thus obtained are detected. CONSTITUTION:First, a tin tetrachloride aqueous solution is neutralized by ammonia in the coexistence of ammonium nitrate to obtain a while sediment mainly composed of beta stannic acid, when pH at the neutral point is preferably 6.8-7.0. Then, the white sediment is calcinated at 400-700 deg.C to obtain tin oxide, which is molded into the shape of an element in an appropriate size, preferably about 1mm-5mm square and then, sintered by heat at 500-700 deg.C to obtain a detection element. The detection element thus obtained changes in the electric resistance of the element corresponding to the concentration of gaseous hydride.

Filed: 1986-10-06
Abstract: PURPOSE:To detect the concn. of the predetermined liquid in a liquid mixture with good accuracy, by measuring the change in the electrostatic capacity between both electrode plates changed in the interval therebetween caused by the swelling of a swelling body. CONSTITUTION:When a sensor main body S is supported in a fuel tank T, a fuel mixture F passes not through each piercing hole 11a of an upper wall 11 to flow in an upper casing member 10 to be penetrated in a swelling member 60 from the outer peripheral end surface thereof but also through each piercing hole 71 of an upper side electrode plate 70 to be penetrated in the swelling member 60. The swelling member 60 has a property swollen by alcohol in the mixture F and is swollen against the elastic force of an elastic plate 40 to increase the interval between lower and upper side electrodes 50, 70 and the electrostatic capacity between both electrodes 50, 70 is reduced. A signal processing circuit E generates a pulse signal having the frequency based on the electrostatic capacity changed. Since this frequency uniquely corresponds to the concn. of alcohol in the fuel mixture F when said pulse signal is utilized, the supply of the fuel mixture F can be properly controlled.

IPC: E04C5/18
Filed: 1993-09-24
Abstract: PURPOSE:To simplify construction work by bending the toes of reinforcements in U-shape in such a fashion that they are placed one upon another and forming a disk-shaped space and forcing a cylindrical wedge into the disk-shaped space. CONSTITUTION:The toes of reinforcements 4 are bent in U-shape respectively so as to join and the reinforcements 4 processed in U-shape at their joint positions are placed one upon another, thereby forming a disk-shaped space. Then, a steel-made column is cut at an obtuse angle at the central part of the column in the longitudinal direction. Two cut and separated pieces of wedges 2 and 3 are forced into the reinforcements 4 in the disk-shaped space, thereby forming joints. It is, therefore, possible to absorb accuracy errors of reinforcement work by the force of the wedges and hence simplify accuracy control.

Title: Microwave discharge light source device
Inventor: NATORI SHIGERU
IPC: H01J65/04
Filed: 1984-11-12
Abstract: PURPOSE:To prevent the tube wall of a no-electrode lamp from thermal damage due to a generated hot spot by making a cooling wind to flow through between a no-electrode lamp and an internal body contained through a space. CONSTITUTION:The gas inside a no-electrode lamp 8 is discharge-excited by a microwave for being heated and radiated. Simultaneously, the wind sent from a cooling fan enters the first ventilation tube 16 through a guide for ventilation while said wind goes through the space 21 between the no-electrode lamp internal body 14 and the no-electrode lamp 8. At this time, the sent air takes heat generated from the no-electrode lamp 8 from lighting away from the whole peripheral surface of the tube wall of the no-electrode lamp 8 for cooling the no-electrode lamp 8. Then, the air having cooled the no-electrode is exhausted outside through a ventilation tube 17. Thereby, no hot spot comes to generate on the tube wall of the no-electrode lamp.

Filed: 1994-09-30
Abstract: PURPOSE: To prevent by a simple constitution the rupture of a hose and coming- off from a hose joint due to excessively increasing a pressure in the hose having elasticity. CONSTITUTION: In the case of such as blinding a jet hole 8 of a nozzle 1 with foreign matter 9, a pressure Pkg/cm<2> is applied to a rubber hose 2 by pressure water.

Title: Driving mechanism of printing head
Inventor: SUEYOSHI KENICHI
IPC: B41J2/28
Filed: 1985-10-23
Abstract: PURPOSE:To furnish a printing head driving mechanism with a reduced loss time and with an increased printing speed, by providing an electrostrictive element for increasing the amount of flexibility of a leaf spring which is the driving source of a printing head, and by electrifying the element only in printing to keep the leaf spring supporting the head away from a head-driving element so as to increase a force of restoration. CONSTITUTION:An electrostrictive element 5 which is expanded by electrification is attached between a leaf spring 6 supporting a printing head element 1 to be driven and a head-driving element 7. When the element 5 is electrified on the occasion of a printing operation of the head element 1 to be driven, the spring 6 located at a position B is moved instantaneously to a position B''. Therefore a curve (b) of the force of restoration of the spring 6 can be transferred to a curve b' and further to a curve b'' extending beyond a curve (a) of the force of attraction of a permanent magnet 3. Thereby a loss time from an electrification start point A to a printing operation start point B is reduced, a spring charge energy in printing is increased, and acceleration property is improved. The electrification of the element 5 is discontinued simultaneously when the electrification of a coil 2a is discontinued, and thereby an armature 1b is attracted onto the attracting surface 8 of an iron core.

Title: Manufacture of wooden heat treated material and use thereof
Inventor: TAKEUCHI HISAYA
IPC: C05G3/80
Filed: 1997-08-19
Abstract: PROBLEM TO BE SOLVED: To prevent decomposition and rotting properties owing to a microorganism and rotting bacterium while remarkable decrease of strength such as in charcoal is prevented by a method wherein wooden crushed material, waste, etc., are slightly heat treated at a specific low temperature. SOLUTION: Wooden waste such as chipper dust or the like which is generated in manufacture of chips by crushing wood is heat treated at a low temperature of 150 to 350 deg.C, and carbonization of a light degree by dehydration, and a crosslinking bond between cellulose molecular chains, between hemicellulose molecular chains, etc., are generated in the wood. Thereby, rapid decomposition by soil microorganism is enabled to be prevented. Further, by heat treatment at such the low temperature, decrease in strength of wood is by far small by being compared with charcoal, an occurrence like being crushed during operation is almost gone, and its shape can be kept for a long time.  Furthermore, even with an external heating type carbonization furnace or with a self-sustained combustion type carbonization furnace, an energy cost is low and a yield is raised because of heat treatment at a low temperature. Therefore, a manufacture cost becomes very low.
