Title: Heat pipe type heat exchanger
Inventor: ITOU KANICHI
IPC: F28G3/00
Filed: 1977-10-28
Abstract: PURPOSE: To remove the fouling of the outer surfaces of heat pipes, by a washing effect based on the tumbling action of solid particles by filling and holding solid particles to the heat exchanging chambers of a heat pipe type heat exchanger while horizontally turning the heat exchanging chambers.  
     CONSTITUTION: A heat exchanging chamber 4 at the high temp side and a heat exchanging chamber 4' at the low temp side are shaped by means of a circular truncated cone-like outer casing 3 and a partition wall 2, and heat pipes 1 are fixed in a form that the pipes penetrate both heat exchanging chambers. Rotary joints that fluid can enter and leave to each heat exchanging chamber are mounted while a tire 11 is installed to the outer case and a roller 12 is disposed, and a main body is turned by means of a driving gear 13 centering around a horizontal shaft. An appropriate quantity of sand with a suitable particle size are held in the heat exchanging chamber 4. If a porous plate 17 and a net are disposed to an outlet portion communicating with a cylinder 5 at the outside of the lower current side of the heat exchanging chamber 4 in order to prevent the dispersion and outflow of sand, fouling can be removed more effectively.

Title: Concrete mixer
Inventor: UKITA KAZUAKI
IPC: B28C5/14
Filed: 1989-05-23
Abstract: PURPOSE:To obtain uniformly kneaded ready-mixed concrete in short kneading time by a method wherein a plurality of nozzles are provided at proper intervals on respective feed water pipes, each of which is provided parallel to rotating shaft at the position outside the rotating shaft, so as to direct each nozzle to the region between the rotating shafts. CONSTITUTION:The starting of the jetting of water from nozzles 12 is performed simultaneously with the starting of the rotation of rotating shafts 6a and 6b. Next, the predetermined amount of cement and sand is charged from a hopper 4 into a kneading chamber 2. At this stage, though the fear of the interior of the kneading chamber 2 being filled with finely divided powder of cement and the like exists, said fear is supprssed by the sprays jetted from the nozzles 12. Further, the water containing in material increases with the elapsed kneading time and when the amount of the water becomes the proper one, gravel is charged and the remaining water is sprayed from the nozzles under the condition that the rotating speed of kneading arms is lowered so as to suppress the flying of paste-like material. After the predetermined kneading time, ready-mixed concrete, which is properly kneaded and homogeneous, is obtained.

Title: Manufacture of nonvolatile semiconductor device
Inventor: ITO RYOICHI

Abstract: PURPOSE:To make the uniformity of a natural oxide film favorable, and to improve the uniformity of a thin oxide film so that it may prevent the variation of initial threshold voltages on the elimination side being the electric characteristics of the MNOS transistor of an EAROM by introducing a process of cleaning the surface of an exposed substrate in cleaning solution based on hydrogen peroxide. CONSTITUTION:The process of exposing the surface of a substrate 11 by chemically etching and removing a first oxide film 13 provided at the surface of a semiconductor substrate 11 of one conductivity type, the process of cleaning the surface of the exposed substrate 11 in cleaning solution based on hydrogen peroxide, and the process of providing a second oxide film 15 at the surface of the cleaned substrate 11 are provided. For example, the surface of the Si substrate 11 is exposed by etching the oxide film 13 with buffered hydrofluoric acid, and the surface of the Si substrate 11 is cleaned at a temperature of 60-80 deg.C for 15 minutes in the cleaning solution of H2O2:NH4OH:H2 O=1:1:8. Next, the second thin oxide film 15 is oxidized at 600-700 deg.C for 2 hours in oxygen gas atmosphere and is made into the thickness of 5nm or below, and thereon a nitride film 16 about 20nm thick and the second polycrystalline silicon 17 doped with phosphorus are formed.

Title: Hermetic package
Inventor: DERKITS JR GUSTAV EDWARD
IPC: H05K5/06
Filed: 1998-05-13
Abstract: PROBLEM TO BE SOLVED: To reduce or remove gaseous hydrogen from the interior of a package, by a method wherein a package structure is constituted into such a form that a second layer prevents a surface oxide layer from being formed and the hydrogen, which is moved from the periphery of the package to a first layer, is fixed as a hydride. SOLUTION: Hydrogen to come out from the atmosphere in a package is absorbed in the surface of a second layer 32 and is turned into a hydrogen solvent compound, whereby the compound penetrates into the interior of the layer 32. The hydrogen solvent compound is moved into the interior of a first layer 33 by an endothermic reaction which generates 1.1 eV per atom. The compound is precipitated (fixed) as a titanium halide by another endothermic reaction which generates 0.2 eV per atom. This endothermic reaction functions so as to fix the hydrogen in the layer 33 made of titanium and prevents the hydrogen from returning to the layer 32.  When the layer 32 made of a noble metal is used, the reactivity of the hydrogen and the formation of the oxidized surface of the layer 33 made of the metal are prevented by the layer 32, whereby the surface of a package structure is maintained in an open state to make easy to accept the hydrogen.

Abstract: PURPOSE:To permit automatic correction of the rolling pose of the paddy working machine on turning, by providing a center ground sensor which can move vertically and roll on the front at the middle point between the left and right grounding sensor 18a, 18b. CONSTITUTION:The water paddy working machine is provided with a couple of ground sensors 18a and 18b on both left and right sides so that they can freely ascend and descent independently from each other. A relative difference in ascending and descending is sent to the rolling control valve 17 by the grounding pressures to control rolling. Additionally, a center ground sensor 7 which is vertically movable around the rear support point P2 and rollable is set on the front of between the ground sensors 18a and 18b to send changes of grounding pressure to the rolling control valve 17. A contact pin 34 is projected in front of the sensors so that the rising motion over the setting value for the center ground sensor 7 is controlled by contact at only one point. Thus, the rolling becomes controllable on turning, even when the body is inclined.

Abstract: PURPOSE:To heighten safety and to reduce the wastage of electric power, by a method wherein, when dusts are not detected at a dust-sensing part during a specified time preset by a time device, a motor is stopped by a controlling device. CONSTITUTION:In a suction cleaner, a timer circuit part 31 is contained in a phase-controlling circuit part 30. When dusts are intermittently passed at a dust-sensing part, the speed of a motor 2 is controlled so as to be increased against a preset speed.

Title: Elastic support base supporting first member to second member
Inventor: RICHIYAADO DEITSUKU OBADARU
IPC: B62D33/06
Filed: 1983-07-18
Abstract: A resilient mount is disclosed for supporting a cab structure on the chassis of a vehicle. The mount includes a cup-shaped housing which is attached to the chassis such that it can hold a quantity of fluid. A stem which is attached at one end to the cab structure projects through the top of the housing and engages with a fitting which is completely retained in the housing. A pair of flexible members are tightly fitted into the housing above and below the fitting and cooperate to form a fluid cavity therebetween. The top flexible member has an opening therein through which the stem passes while the bottom flexible member contains at least one fluid passage which permits fluid flow therethrough as the size of the passage varies due to the flexing of the bottom flexible member. The mount also includes a valve for regulating fluid flow between the cavity and the fluid passage as the stem moves in and out or laterally relative to the housing. This mount provides both hydraulic and resilient damping of the cab structure relative to the chassis.
