IPC: C21B15/02
Filed: 1991-04-15
Abstract: PURPOSE:To effect stable thermit smelting reaction and to product high-quality metal or alloy at high yield. CONSTITUTION:Metal or alloy is produced by introducing a mixture source material essentially comprising a metal oxide powder and an aluminum powder in a reaction furnace and effecting thermit reaction. In this process, the mixture source material in an amt. corresponding to one batch is divided into several parts. The divided source material is controlled in a manner that the calorific value of each part differs each other and then introduced in the reaction furnace to deposit in a laminar state successively in the order of small calorific value to effect the thermit reaction.

Title: Fan shroud
Inventor: SUSA SUMIO
IPC: F04D29/54
Filed: 1979-08-24
Abstract: PURPOSE: To simplify manufacturing of a fan shrond used for blowing air to the radiator of an automobile or the like to a large extent, by separating the shroud into two sections, and manufacturing one of the two shroud sections by way of one- piece molding integrally with a flange portion, arm portions and clamping stays.  
     CONSTITUTION: In accordance with the present invention, a shroud is constructed separately in the first shroud section 8 and the second shroud section 20. Therefore, a resin mold or a die-casting mold necessary for integrally molding of a flange portion 4, arms 7 and clamping stays 9, constituting a part of the shroud, can be formed in an extremely simple structure, so that manufacturing of the shroud can be simplified extremely. Further, by designing the connecting portions 8b, 20a of the first and the second shroud portions 8, 20 in freely replaceable manner, it is enabled to use the second shroud portion 20 for multiple purposes only by changing the first shroud section 8 obtained by way of molding integrally with clamping stays 9. Thereby, manufacturing costs of the shroud can be lowered considerably.

IPC: F23N5/12
Filed: 1990-04-24
Abstract: PURPOSE:To enable a combustion range at a high air ratio side to be expanded, and both a low Nox and a high TDR to be accommodated by a method wherein a detection circuit with a flame rod being a plus side and a burner main body being a minus side is constructed, a DC electrical field with a wall of a DC electric field being a plus side and the burner main body being a minus side is added to grasp a combustion state. CONSTITUTION:During a combustion, a flame rod 8 is disposed in respect to a flame 7, a detecting circuit 9 with a flame rod 8 being a plus side and a burner main body 12 being a minus side is constructed so as to detect an ion electrical current present between the flame rod 8 and the main burner 5. A threshold value of the ion electrical current is set in respect to an amount of combustion and if the detected ion electrical current is a threshold value or more, it is judged as a normal combustion to continue the combustion and in turn, if the value is a threshold value or lower, it is judged as an abnormal combustion to stop the combustion. A DC electrical field is added, such that a DC electrical field wall 10 is set to a plus side and the burner main body 12 in set to a minus side. Positive ions in the flame 7 are retracted toward the minus side and even if an amount of combustion or an air ratio is increased, the flame 7 is adhered to the main burner 12 and then a blown-off state is hardly produced.

Title: Digital/analog converting circuit
Inventor: MIYAKE MASAYASU
IPC: H03H17/02
Filed: 1987-05-01
Abstract: PURPOSE:To enhance the effect similar to that with a sampling frequency increased without increasing the circuit scale remarkably by inserting an interpolation circuit comprising a few components between a digital signal processing section and a DA converter. CONSTITUTION:A digital input signal A is retarded by one sampling time only by a delay circuit T11 in an interpolating circuit 4 and goes to an output signal B, and the signals A, B are subtracted by a subtractor 12 and the result goes to a signal C. The signal C is divided into 1/2 by a 1/2 circuit 13, and goes to an output signal D. The processing above shows the case of the number of interpolation points to be '2'. Then the signal D and the original signal B are added by an adder 14 to obtain an output E. The output E is the result of linear interpolation between the sampled signals A and B. Then, the signals E, B are fed to a switch 15, from which the signal B is outputted with a clock G at logical '1' and the signal E is fed when the clock G is logical '0' and the resulting signal goes to F. The signal is converted into an analog by a DA converter 16, filtered by an LPF 17 to obtain an output signal I. The sampling frequency is twice that of a conventional frequency in the signals, and no steep attenuation characteristic is required for the filter LPF.

Filed: 1982-06-24
Abstract: PURPOSE:To avoid erroneous control of a host processor due to fault data, by providing a detecting circuit, etc. to deliver a fault signal when the common mode voltage higher than the reference level is applied. CONSTITUTION:A fault signal is delivered when the common mode voltage higher than the reference level is applied and held at an output register together with the input data given from an A/D converting circuit. Then the information of the output register is read into a host processor. For instance, a prescribed channel input of a multiplexer 1 is designated via a multiplexer driver 6 and by means of signals ADR and MPX.EN which are given from a host processor 5. Then detecting circuits 7 and 8 compare the common mode voltages contained in plus and minus side inputs Va and Vb of an amplifier 2 with reference voltages E1 and E2. When the excessive common mode voltage higher than the reference level is detected, a fault signal is sent to an output register 4 and then read into the processor 5 together with the input data given from an A/D converting circuit 3.

Title: Semiconductor device
Inventor: TAKAHASHI HIROSHIGE
IPC: H01L21/316
Filed: 1982-06-22
Abstract: PURPOSE:To reduce influence of polarization due to phosphorus and obtain a device with less fluctuation of threshold value by stacking an oxide film including phosphorus on an oxide film not including impurity. CONSTITUTION:A non-volatile memory device is formed by the conventional method, and an oxide film 10 including phosphorus in the thickness of about 2,000Angstrom  is stacked on an oxide film 9 not including impurity in the thickness of about 6,000Angstrom . Therefore, in the case of a non-volatile memory device in the double electrode structure, the film 9 exists even when the phosphorus within the film 10 is poralized, electric field intensity is weakened due to film thickness and thereby influence of electric field due to poralization is reduced. Accordingly, fluctuation of threshold voltage of the element itself can be reduced almost to zero, thereby stabilizing the function and improviding performance of semiconductor device.

In the case of a change by 2, an optimum dot preceding by two steps is decided by the decision of conditions. At the same time, an optimum dot preceding by one step is decided clearly regardless of the decision of conditions.
