Title: Fluidized bed heating burner and fluidized bed combustion apparatus
Inventor: SHIZUKUISHI SHIN
IPC: F23C5/08
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To prevent particles from entrering even when a burner is disposed within a fluidized bed and on a side surface and hence directly effectively execute heating by protruding an injection cylinder from a combustion chamber including a flame stabilizer therein, and constructing a cross section of the injection cylinder to be smaller than that of a combustion chamber. SOLUTION: An injection cylinder 5 is protruded on one side of a combustion chamber 1 through a tapered part 6, and a cross section (a) of the injection cylinder 5 is adapted to be smaller than that A of the combustion chamber 1 (A>(a)). When the injection cylinder 5 is positioned in a fluidized bed with a horizontal attitude or its opening end is positioned on a side surface of the fluidized bed, a length L of the injection cylinder 5 from an opening end is assumed to be L>d/tan α when a cross section height is assumed to be (d), and an angle of repose between particles used for the fluidized bed and a member of the injection cylinder 5. Hereby, even in a combustion interrupted state, the particles are prevented from entering the combustion chamber 1. Thus, the fluidized bed is effectually heated.

Title: Method of producing silicon epitaxial wafer and silicon epitaxial wafer
Inventor: EBARA KOJI
IPC: H01L21/205
Filed: 1999-11-10
Abstract: PROBLEM TO BE SOLVED: To provide a method of producing a silicon epitaxial wafer, which is capable of efficiently producing the epitaxial wafer in which plural epitaxial layers are stacked through buried ion implanted layers and by which the silicon epitaxial wafer small in diffusion of the formed ion implanted layers in the lateral direction can be obtained. SOLUTION: After ion implantation, the heat treatment for recovering crystal is carried out under a hydrogen atmosphere, thereby a phenomenon that the surfaces of the ion implanted layers 71, 72 are made rough is remarkably suppressed even when oxidation treatment prior to the ion implantation is not carried out. Accordingly, in a method of producing the epitaxial wafer having burying ion implanted layers 71', 72', the oxidation treatment prior to the ion implantation can be neglected and further it becomes possible to carry out the ion implantation using only a photoresist film as the mask 64.  As positive oxide film forming treatment including the oxidation prior to the ion implantation to the epitaxial layer 3 is neglected, the number of thermal hysteresis loaded on the buried ion implanted layers 71', 72' is lowered, thereby, the diffusion in the lateral direction is effectively suppressed. As the process of forming/removing the oxide film is not needed, the number of the processes for producing the epitaxial wafer can markedly reduced.

Title: Ink jet recording method
Inventor: FUJII MASAHIKO
IPC: B41J2/205
Filed: 1990-11-24
Abstract: PURPOSE:To obtain a stable image without causing the consumption of electricity to increase and without being affected by exterior environment by applying to a heater a pulse smaller in energy than a printing pulse before applying the printing pulse. CONSTITUTION:An ink jet recording is effected by applying a printing pulse to a heater provided on a base plate and flying ink drops onto a recording medium by the pressure of the vapor bubbles formed under heat produced by the heater. Before applying the printing pulse, a pulse 21 smaller in energy than the printing pulse 20 is applied to the heater. The temp. of ink near the heater is raised by the heater energized by the pulse 20 to permit the volume of the bubbles being formed to increase. In this way the volume of the ink drops to be injected can be increased. The pulse 21 to be applied before the printing pulse may be applied only when ambient temp. is low.

IPC: E04D5/14
Filed: 1990-11-22
Abstract: PURPOSE:To improve the performance as connecting member by interposing a vulcanizable rubber in the superposition part of a thermoplastic elastomer sheet and a vulcanized rubber sheet and joining both the sheets by pressurizing through heating. CONSTITUTION:An auxiliary connecting sheet 1 is constituted by superposing a thermoplastic elastomer sheet 2 and a vulcanized rubber sheet 3 and joining the sheets 2 and 3 by pressurized vulcanization through heating, having an unvulcanized rubber sheet interposed.

Title: Pn code acquisition circuit
Inventor: KATAOKA NOBUHISA
IPC: H04J13/00
Filed: 1987-12-18
Abstract: PURPOSE:To acquire the PN code at a high speed even when the accuracy of an AFC circuit is not enough by constituting an adder means by plural adders with different addition number. CONSTITUTION:An adder 14 with different addition stage number from that of an adder 11 constitutes an addition means together with the adder 11. Since the number of addition stages of both the adders 11, 14 constituting the adder means differs from each other, even if a frequency deviation component is included in the reception code inputted to a shift register 8, the result of correlation with less effect of the frequency deviation is outputted. Thus, the PN code is acquired at a higher speed than that of a conventional circuit using only the output of the adder 11 by using the output of the adder 14.

Title: Controller of series multiplex inverter
Inventor: SAKAMOTO KIYOSHI
IPC: H02M7/48
Filed: 1995-12-11
Abstract: PROBLEM TO BE SOLVED: To eliminate the output voltage distortion of an inverter and suppress a current fluctuation by a method wherein, when the amplitude of the carrier wave signal of one of modulation systems is close to a maximum amplitude value, it is switched to the carrier wave signal of the other modulation system so as to have its amplitude close to a maximum amplitude value. SOLUTION: A selection circuit 5 selects an amplitude signal and a period signal which are outputted by a unipolar PWM setting circuit 4b and outputs an amplitude signal 501 and a period signal 502. A triangular wave generator 6 generates a triangular wave Ec0 in accordance with the values of the amplitude signal 501 and the period signal 502. In the case of a unipolar modulation, the triangular wave signal Ec0 whose amplitude is varied between -E/2 and E/2. A bias adder 9 adds two types of biases, i.e., +E/2 and -E/2, to the triangular wave signal Ec0 is outputted and outputs two carrier waves Ec1 and Ec2 whose frequencies and phases are identical to each other. With this constitution, the distortion is eliminated from the output voltage of a series multiplex inverter and the fluctuation of its output current can be suppressed.

Title: Forming method of silicon nitride thin film by chemical vapor growth method
Inventor: KAJI SHIGEHIKO
IPC: H01L21/318
Filed: 1988-12-22
Abstract: PURPOSE:To increase maintenance efficiency and the security of an apparatus, and improve the controllability of film thickness by introducing inert gas together with material gas into a thin film forming chamber of a thin film forming apparatus. CONSTITUTION:At the time of forming a thin film, inert gas is introduced together with material gas of silicon source and material gas of nitrogen source into a thin film forming chamber of a thin film forming apparatus. As the flow rate of the material gas decreases, the ratio of unstable pressure period t2 to deposition period t1 increases, so that film thickness control becomes difficult. However, by simultaneously introducing the inert gas and increasing the total flow rate of supply gas, the ratio to evacuation amount increases, pressure change decreases, and t2 is shortened. Further the partial pressure of the material gas in the thin film forming chamber decreases, so that the deposition speed is lowered and t1 becomes large. As a result, the ratio t2/t1, that is a ratio of the unstable pressure period to the deposition period, decreases and the controllability of film thickness is improved.

Title: Image forming device
Inventor: TAKECHI RYUTA
IPC: G03G21/00
Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To enable coating within a range where image quality is high by comparing read toner image data with original image data, discriminating the presence of the abnormality of a formed toner image, and controlling the coating quantity of a low frictional agent. SOLUTION: After fixed initializing processing is executed (S1), image output processing (S2), image reading processing (S3), comparing/recognizing processing (S4), low frictional agent coating quantity control processing (S5) and engine state processing (S6) are executed in order, to check whether an error occurs or not (S7). When the error does not occur in the step S7, returning to the step S1 is attained to execute main processing. When a normal error in an image forming device such as paper jamming, etc., occurs, fixed error processing for eliminating the error is executed and operation is stopped (S8). Thus, the image forming device uses a controller to execute the main processing and adjust the coating quantity of the low frictional agent.
