Filed: 1982-05-13
Abstract: PURPOSE:To exhaust air generated in a pump and pipings automatically and effectively by furnishing an automatic exhaust device, which accommodates a float valve to open and shut the exhaust hole while is moved approx. prombly by the instreaming air from an air chamber. CONSTITUTION:Bubbles generated in a hot-water circulating pump as illustrated and associated pipings flow in a case 13 together with hot water 15 from an air chamber 11 through a male threaded part 13a. In the case of less amount of air production, the level 15a of hot water 15 in the case 13 rises, and the valve element 16 floats up in the case 13 to block the exhaust hole 14a automatically. In the case of much production bubbles, the level 15a of hot water 15 in the case sinks, so that the valve element 16 sinks in the case 13 to open the exhaust hole 14a automatically for exhaustion of the air. Thus the air generated in a pump and associated pipings can be exhausted automatically and effectively, which assures prevention of noise generation, air locking, etc.

Filed: 1997-04-01
Abstract: PROBLEM TO BE SOLVED: To maintain a pneumatic heat insulation effect that can be achieved by a recess in non-use even if a material such as cover is loaded on a top part by enabling protrusion-and-recess processing on both outside faces as a soft foam body capable of molding a heat insulation material and providing protrusion-and-recess processing on both outsides of a main body. SOLUTION: A heating element 2 being a heat source is embedded and fixed in a soft foam body 9 and comprises a main body 10. Over a top face, a well- designed cover 11 is covered. The soft foam body 9 is provided with a recess 12 on a floor face. By setting an area of independent recess 12 each other to 30% or more of each protrusion-and-recess faces, even if a material such as over 11 is loaded on a top part, a space generated between floor faces obtained by the recess 12 is ensured. Since there is a protrusion and a recess on the top face of the floor surface, a contact area with the floor surface and the cover 11 can be reduced by a part of the recess 12 with respect to a full-face flat. Thereby, heat conduction is decreased, and a heat insulation effect can be increased.

Title: Semiconductor device having decreased time dependency dielectric breakdown
Inventor: BURUUSU JIEFURII FUITSUSHIYUBA
IPC: H01L21/336
Filed: 1991-04-15
Abstract: PURPOSE: To prevent time-dependent dielectric breakdown by forming an inversion layer on an electrode and an adjoining surface region doped with an impurity which, when a bias voltage of a specified level or above is applied to the electrode, reduces voltage drop across both the ends of an insulator layer. CONSTITUTION: The applied voltage between a gate 15 and the inversion layer in a channel area 16 is expressed as Equation I, where Va is applied voltage, Vs is the voltage drop across both ends of an underlayer depletion layer, Vox is the voltage drop across both ends of an oxide film 18, Vp is the voltage drop in the depletion layer of the gate electrode 15, and Vms is the work function between the substances of the gate electrode 15 and the underlayer 10. Vox is calculated as in Equation II. It turns out from the equation that the voltage drop across both ends of the insulator 18 is in linear relation with the applied voltage and the voltage drop at the gate electrode. Therefore, letting Va be constant, Vox is reduced as Vp is increased. The depletion layer voltage drop Vs and Vp depend on the applied voltage Va and the level of doping in the underlayer and the gate electrode 15.  When Vp in the gate insulator lightly doped is increased, therefore, Vox is reduced, and it is possible to prolong time-dependent time of failure.

Filed: 1997-04-01
Abstract: PROBLEM TO BE SOLVED: To provide an image forming method for preventing falsification, with excellent workability by coloring the surroundings of a printing part with a coloring component included in toner. SOLUTION: In the case of forming an image on a printed material, the surroundings of the printing part are colored by the coloring component included in the toner. By this constitution, the surroundings of the printing part of the printed material are colored so that even if toner grains are physically removed to attempt the falsification of the numbers of securities, etc., in the case the fixation of toner powder is insufficient, evidence of printing is left because a surrounding part is colored, to prevent such an illegal falsification. As the printed material, an arbitrary one can be used. In other words, a special limit is not set but preferably a sheet of paper is used. Further, as the surroundings, normally most of the surroundings of the printing part are mentioned but it is good that the surroundings of at least a part of the printing part are obtained.  Further, as the image forming method, it is preferable that an electrophotographic method can be used.

Title: Blank charger
Inventor: ISHIKAWA HIDEHO
IPC: B65H19/10
Filed: 1981-05-30
Abstract: PURPOSE:To charge a fresh blank securely by a method wherein just before a projection on a plate provided on a blank clamping table reaches a carrying projection on a tractor the blank is brought backward by a stopper, slipped out of projections on the plate and caught by the carrying projections on the tractor. CONSTITUTION:When a blank clamping table 11 is revolved in an A-direction, carrying holes for the blank 5 slip out from projections 12 fixed to a block 14. The blank 5 does not go backward because the blank 5 is supported by projections 13. When the blank clamping table 11 continues to revolve, a stopper 17 collides with part of a plate 15, stops revolution, the projections 13 begins to slip out from the carrying holes of the blank 5 and finally projections 13' only catch the carrying holes. The carrying holes of the blank 5 come into projections 18' of the tractor facing the projections 13' and each hole is set sequentially into each projection 18. This sequence of operations is completed in a short time, therefore, the air pressure given to the blank 5 on the blank clamping table 11 during revolution is too large to bring the blank 5 backward.

Abstract: PROBLEM TO BE SOLVED: To stably ensure a mixing agitating efficiency by disposing a plurality of liquid supply tubes in parallel or lattice state in a secondary combustion chamber, and diffusing combustion air to unburnt gas rising from a combustion air diffusing hole at a downstream of the supply tube. SOLUTION: A plurality of fluid supply tubes 2 are horizontally disposed at an interval in parallel across a secondary combustion chamber 1 to form parallel gas channels 3. Gas generated in a fluidized bed (primary combustion chamber) is exhausted from a top of a furnace via the channels 3 of the tubes 2. Unburnt gas of the rising gas is burnt while bearing mixed with combustion air diffused down from combustion air holes 4 of a liquid supply tube 2, combustion gas is uniformly distributed via the channels 3 of the tubes 2 disposed in parallel, and exhausted from the top without drift. Thus, mixing agitating efficiency of the unburnt gas can be stably held, and hence combustibility is improved.
