IPC: F23G5/00
Filed: 1987-02-06
Abstract: PURPOSE:To obtain a desired combustion performance, and to enable ashes to be taken out of a furnace in a dry state, by positioning the after-flow part of a combustion stoker in a fluidized-bed furnace, and by forming feed paths of matters to be incinerated by determining the distance between water pipes on the after-flow side of a combustion stoker nearly equal to or below the distance between air diffuser pipes in the fluidized-bed furnace. CONSTITUTION:The after-flow part of a combustion stoker 3 is extended and is positioned in the furnace 7 of a fluidized-bed furnace 5, and the distance 'D1' between water pipes 4 which are provided along the inside wall of a combustion stoker 3 on the after-flow side is determined nearly equal to or below the distance 'D2' between the air diffuser pipes 6 in the fluidized-bed furnace 5. Among the pre-burned matters to be incinerated, being fed into the after-flow part of a combustion stoker 3 and being pre-burned there, the ones which are smaller than the distance 'D2' of air diffuser pipes 6 in the fluidized-bed furnace 5 pass through the feed paths 8 of the matters to be incinerated and are stoked into the fluidized-bed furnace 5. The unburned matters to be incinerated fed into the fluidized-bed furnace 5 are after-burned and are burned completely there. Ashes are dried and are discharged to the outside of a furnace from a discharge port 12 by a discharger 11. The matters to be incinerated which can not pass through the feed paths 8 of the matters to be incinerated are burned further in the combustion stoker 3.

Title: Ink discharge recording device
Inventor: YAMASHITA AKIHIRO
IPC: B41J2/05
Filed: 1995-02-14
Abstract: PURPOSE: To obtain an energization type ink jet printer with a head which is small in size and has a long service life. CONSTITUTION: In a discharge section 1, electrodes for supplying electric current to a conductive ink is made to be common among adjacent nozzles. An electric signal to be supplied to the electrodes from driving circuits D1-D6 of a supply section 2 is made to be alternating current. The phase of the electric signal is made to be the same among the electrodes of the adjacent discharge nozzles such that the electric current does not flow to the conductive ink of the nozzle which does not supply the current. Further, in a control section 3, the frequency of the current signal to be supplied to the electrodes from the driving circuits D1-D6 of the supply section 2 is temporarily doubled in such a manner that direct current, which causes deterioration of the electrodes when the driving times of the nozzles are different, does not flow.

Title: Vessel for liquefied gas
Inventor: MAEDA YASUHIRO
IPC: F17C9/02
Filed: 1980-02-29
Abstract: PURPOSE:To permit inert gas to be generated by a desired amount by penetrating the rod-shaped endothermic body equipped with fins into a vessel, allowing the contact with liquefied gas, and allowing the heat of the outside air to be absorbed. CONSTITUTION:When an endothermic body 6 is pushed gradually into a vessel body 2, the rod part 6a contacts with liquefied gas 7. The endothermic body 6 described above is made of the material having a high heat conductivity, and the thermal exchange between the outside air can be performed effectively by means of fins 6b, so the liquefied gas 7 is vaporized by the outside air heat source which is absorbed by the endothermic body 6 and forms inert gas. The inside of the vessel body 2 is filled with the gas described above, and the internal pressure increases, and the gas is supplied to the user side from a gas induction pipe 5. As the liquefied gas reduces with evaporation, if the endothermic body 6 is inserted into the vessel body 2 at proper times, liquefied gas 7 can be vaporized continuously by the desired amount.

Title: Treatment of gel and treating device
Inventor: KOIKE TAKASHI
IPC: C01B33/158
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To obtain a dry gel having a large pore diameter, small bulk density and a desired compsn. without causing shrinkage due to surface tension and without influences of other gels by housing each wet gel prepared by a solgel method in a respective pressure-resistant container, heating plural pressure- resistant containers at one time to make the inside of the pressure-resistant container in a supercritical state to treat the gel. SOLUTION: A wet gel 2 is individually housed in a pressure-resistant container 1, and plural pressure-resistant containers 1 which house the gel 2 are housed in a heating device 6 and heated at one time so that the inside of the pressure-resistant container 1 is rendered to a supercritical state of the solvent 3 which fills the pores of the wet gel 2. Then a valve 5 of the pressure-resistant container 1 is opened to discharge the vapor of the solvent 3. By discharging the vapor, the pressure of the system decreases and the supercritical fluid is discharged as a gas. In this process, since no air-liquid interface is present, no surface tension generates in the pores of the gel, no stress is added to the pore, and the gel does not contract. Therefore, a dry get without cracks can be obtd.

Title: Aluminum materials to be joined by resistance welding
Inventor: TANIGAWA HISAO
IPC: B23K103/10
Filed: 1993-02-15
Abstract: PURPOSE:To improve continuous spottability of resistance welding by forming an oxide film having the specified thickness on the surface at the side to face an electrode of aluminum materials. CONSTITUTION:The aluminum materials are joined together by resistance welding. The oxide film having the thickness of about 300-1000Angstrom  is formed on the surface at the side to face the electrode of these aluminum materials. The oxide film is made to a boehmite film. This boehmite treatment is desirable to be carried out by using superpure water. Consequently, when the oxide film above about 300Angstrom  is formed, even if resistance welding by using the aluminum materials is performed, covering of the electrode surface by intermetallic compounds such as Al-Cu is decreased, the continuous spottability is improved and lowering of welding performance is prevented as the electrode itself is not defective.

Title: Semiconductor integrated circuit device
Inventor: ARAYA YUKIHIRO
IPC: H03F3/34
Filed: 1992-01-14
Abstract: PURPOSE:To eliminate the offset voltage generated at an output terminal by correcting the offset voltage of a prescribed operational amplifier constituting a signal amplifying circuit to compensate the offset voltage of the signal amplifying circuit. CONSTITUTION:When a gain changeover switch 14 is turned off, that is, a gain switching buffer amplifier 20 is turned off, the signal inputted to an input terminal 1 passes a preamplifier (buffer amplifier) 3 and is amplified by a main amplifier (output amplifier) 8 having the gain set by gain setting resistances 5, 6, and 7 and is outputted to an output terminal 9. At this time, the offset voltage is logically zero in operational amplifiers 3 and 8, but the offset voltage is generated though being a small value in an actual semiconductor integrated circuit. It is probable that the offset voltage having a large value is generated as the output by connecting operational amplifiers in series. However, such correction is performed that the offset voltage is not generated at the output terminal because a preamplifier offset correcting resistance 4 and a main amplifier offset correcting resistance 10 are provided.
