Title: Switchover type gasification of coal by using shaft furnace
Inventor: NISHIO HIROAKI
IPC: C10J3/02
Filed: 1980-10-08
Abstract: PURPOSE: To contemplate the re-use of a shaft furnace and to obtain water gas of good quality with high efficiency, by a method wherein raw lump coal and steam are suppied as a descending stream from the upper part of the furnace during an endothermic period, and powdered coal for fuel, oxygen and steam are supplied from the lower part of the furnace during an exothermic period.  
     CONSTITUTION: During an endothermic period, araw lump coal and steam heated to 800°C are supplied from the upper part of a furnace. This steam is introduced into a boiler to exchange heat for the sensible heat of produced gas heated to 1,000°C and recovered from a furnace belly shown in the lower half of the Figure. The resulting steam heated to 200°C is passed througth a supper heater to exchange heat for the sensible heat of produced gas heated to 1,200°C and recovered from the lower part of the furnace during a gasification period, whereby part of steam passed through the superheater and heated to 800°C is supplied. During an exothermic  period, lump coal is supplied from the upper part of the furnace. Powdered coal,  oxygen and part of said steam passed through the superheater and heated to  800°C, are supplied from the lower part of the furnace to burn coal, whereby temperature in the lower part of the furnace is brought to 1,800W2,500°C. This temperature is necessary for the enadothermic period of a next cycle.

Title: Pattern-forming method
Inventor: MOCHIJI KOUZOU
IPC: H01L21/027
Filed: 1978-11-15
Abstract: PURPOSE: To prevent the swelling during wet development, to increase the selectivity in dry etching, and to form a fine pattern correctly, by the heat treatment of  resist coating after exposure.  
     CONSTITUTION: A substrate is applied with a resist coating thereon, it is then irradiated with light at the desired portion of the coated substrate in order to increase the solubility of the exposed portion. The substrate is successively subjected to after-baking, then to plasma etching in order to remove the unhardened portion of the irradiated portion, hereby forming a pattern. This method makes it possible to use not only a positive-type resist but also a negative type resist, thus making it possible to use etching as the developing means. Even when the wet development is conducted, harmful swelling is prevented effectively. Consequently a submicro- pattern about 0.5μ in size is formed at an excellent reproducibility.

Title: Nox decreasing combustion method
Inventor: SEKIGUCHI YOSHITOSHI
IPC: F23C99/00
Filed: 1984-07-05
Abstract: PURPOSE:To permit to reduce furnace errosion strenously by a method wherein slurry, consisting of powder fuel and water, is supplied into the primary combustion chamber to generate water gas chemical reaction by the powder fuel and water, therefore, an unburnt portion is burnt completely at the low temperature in the secondary combustion chamber. CONSTITUTION:The fine coal of slurry condition is reduced and burnt at the air ratio of 1.0 or under by the primary air 6 in the primary combustion chamber 2. As the slurry consists of the fine coal (b) and water (c), the water gas chemical reaction is advanced at the relative low temperature of 900 deg.C or more as shown by following formula; C+H2O CO+H2, thus, NOx in the primary combustion chamber 2 is reduced efficiently at low temperature by the reducing gas created from above-mentioned reaction. The reducing gas created in the primary combustion chamber 2 (CO gas and H2 gas) and the unburnt portion of the fine coal are burnt completely at low temperature in the second combustion chamber 3, and the generation of Nox in the secondary combustion chamber 3 may be restrained.

Title: Beam splitter
Inventor: KAWAMATA TAKESHI
IPC: G02B5/08
Filed: 1993-05-19
Abstract: PURPOSE:To enhance the adhesion property of films and to prevent the deterioration of the surface accuracy of a substrate regardless of whether the substrate is glass or resin by constituting dielectric thin-film layers as layers contg. either of MoO3 or WO3 formed by a PVD method. CONSTITUTION:This beam splitter has >=1 layers of the dielectric thin-film layers formed on the substrate. One layer of the dielectric thin-film layers is constituted as the layer contg. either of the MoO3 or WO3 formed by the PVD method. The MoO3 and WO3 are the materials which can be easily evaporated by low energy and the suppression of the radiation heat from the evaporating source to a lower level is possible and, therefore, the damaging of the material by the heat does not arise. These materials are more resistant to flawing than CeO2 and ZnS and have relatively high moisture resistance. Further, there is no absorption of visible light if the films are formed in a completely oxidized state. Then, the beam splitter is formable by using the MoO3 and the WO3 as high-refractive index materials.

Filed: 1994-06-22
Abstract: PURPOSE: To stabilize frequencies, facilitate integration, and improve reliability by comparing a comparison signal of high-frequency which is set at a switching control signal generating circuit with a reference signal, and generating a switching control signal. CONSTITUTION: A sawtooth wave, generated in a switching control signal generating circuit 100, is compared with a reference signal, and a stabilized switching control signal is generated. Thus, a frequency of a switching driving signal is stabilized, and the configuration of the system will be simple and easy to integrate. Also, since the condition of zero-voltage switching is optimized at the designing stage by the setting of the reference signals, the switching control will be possible in the optimized condition such that the voltage of the both ends of switching elements 24, 28 is zero. Further, the reliability of the system can be improved by detecting the condition of overheat or condition of overcurrent of the elements 24, 28, and by resetting a drive signal generating part of the circuit 100, in response to the detected results.

Abstract: PURPOSE:To form chemical Ni plating layers which have small internal stresses and are thick efficiently by forming a chemical Ni plating layer to a prescribed thickness then forming a dissimilar metallic layer than forming a chemical Ni plating layer again to a prescribed thickness. CONSTITUTION:The 1st chemical Ni plating layer 21 of about 10-12mu thickness is formed in accordance with a conventional method on the surface of a member to be brazed corresponding to a junction lead wire or the like in a hermetic terminal. A metallic layer of the quality differing from that of the layer 21, for example, a copper plating layer 22, is formed to about 1-2mu by a known method on the layer 21. Again, the 2nd chemical Ni plating layer 23 of about 10-12mu is formed on the layer 22. Then, the chemical Ni plating layers of about 20mu thickness are formed in approximate proportion to the plating time. Since the internal stresses of the layers 21, 23 are small, stripping of the layers 21, 23 does not occur despite caulking.

Title: Dampening water adjustment
Inventor: TAKASE MASUMI
IPC: B41F7/32
Filed: 1987-06-05
Abstract: PURPOSE:To enable adjustment of additive to dampening water to be performed simply and precisely with almost no effect of temperature change by automatically measuring the quantities of water and the additive to dampening water by a weight method, based on a preset desired value, introducing them into an adjustment tank and mixing them. CONSTITUTION:A quantitative indication is made by a weight method through the entry means of quantitative values of additive to dampening water and water, e. g. a keyboard. On the basis of this entry, a solenoid valve for the additive which operates interlocked with a control part opens and consequently, the additive is trans ferred to an adjustment tank from an additive tank by means of a pump. Then its quantity is measured by a device with the ability to measure by a weight method, and the solenoid valve closes to complete the quantitative determination. After this, a solenoid valve for water which operates interlocked with the control part opens in the same way as for the additive, to supply water to the adjustment tank from a water tank. In this adjustment, the quantities of water and additive are measured by a weight method and these are stirred, mixed to obtain dampening water. The dampening water is normally sent to a circulation tank to compensate for a loss. The obtained dampening water contains the precise and stable concentration of the additive.
