IPC: C01D5/16
Filed: 1978-11-28
Abstract: PURPOSE: To obtain high purity sodium sulfate by mixing Cr-contg. salts into a V- contg. aq. sodium sulfate soln. recovered from an exhaust gas desulfurizer; acidifying the soln.; adding a reducing agent to it alkaline to remove chromium hydroxide- base precipitates formed; and concentrating the remaining soln.

After adding a reducing agent such as sodium sulfite or ferrous sulfate the soln. is adjusted to pH≥8 with caustic alkali to form a chromium hydoxide-base insol. substance, which is separation-removed. The remaining soln. is concentrated to obtain sodium sulfate crystals. Thus, high purity sodium sulfate is produced from the vanadium-contg. aq. sodium sulfate soln. recovered from an exhauat gas desulfurizer.

Title: Hybrid integrated circuit device
Inventor: FUJITA SHIGEO
IPC: H01L23/28
Filed: 1983-08-10
Abstract: PURPOSE:To obtain the titled device of excellent moisture resistance and high reliability by a method wherein a semiconductor element and metallic fine wires are covered with an Si series resin and further with an epoxy series resin. CONSTITUTION:The improvement of moisture resistance is contrived by protection of the semiconductor element 22 and the metallic fine wires 23 with the Si series resin layer 30 of a first layer. Further, the layer 30 is coated with the epoxy series resin layer 31 of a second layer. Therefore, the epoxy series resin layer 25 for sheathing adheres to the layer 31, and strains do not generate in the neighborhood of the boundary 26 between the layers 25 and 31, resulting in no change of the resistance value of a printed resistor 28 in the neighborhood of the boundary 26. This construction enables to prevent the cracks and exfoliations, etc. by the improvement of moisture resistance, thus improving the yield and reliability.

IPC: H04B1/7087
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To extend a frequency lock range of AFC processing up to a multiple of ±1/4 of a symbol rate. SOLUTION: A correction data generating section 125 generates correction data on the basis of a polarity of a frequency offset discriminated by a polarity discrimination section 124.

Title: Semiconductor memory driving circuit
Inventor: YAMAGUCHI KUNIHIKO
IPC: G11C11/34
Filed: 1982-08-27
Abstract: PURPOSE:To prevent the lowering of the degree of operation margin due to the variance of the potential of a driving line, by adding clamp circuits, whose one ends are connected to a constant voltage source commonly, to the driving line. CONSTITUTION:The high potential as well as the low potential of word lines W0-Wn have levels clamped. That is, the high potential has the level clamped with the potential of a terminal VH by diodes D10-D1n. The low potential has the level clamped with the potential of a terminal VL by transistors(TR)s Q10- Q1n. By this clamping circuit, the inter-circuit variance of the word line potential is independent of the potential variance in a word driving circuit. Consequently, the inter-circuit variance of the word line potential is reduced. When this clamp circuit is provided on a digit driving line, the same effect is attained. Thus, the lowering of the degree of operation margin due to the potential variance of the driving line is prevented.

IPC: H04L12/00
Filed: 1988-06-15
Abstract: PURPOSE:To avoid congestion of communication of a network at a fault by applying fault ranking in response to the distance from a fault area and deciding the direction of an adjacent area to be sent depending on fault rank information and the relative address of the adjacent area. CONSTITUTION:Each node has a fault rank information table 31 and output priority direction tables 21-24 by relative address code and fault rank information of a 1st priority direction is checked from the message inputted from an input port 10 by an output adjacent area decision processing section 20 and whether the direction of the adjacent area sending the 1st priority direction or the direction of the adjacent area of 2nd and priority directions is decided depending on the fault rank and the relative address. Thus, the fault area is largely detoured or the fault area is detoured after approaching the fault area depending on the relative address, then the communication of the areas adjacent to the fault area is not congested and the communication is spread wide around the fault area.

Abstract: PURPOSE:To improve the evenness in the ion implanting work extensively by providing a grand mask to regulate the passing position of ion beams and a static deflecting electrode to make the horizontal beam component and the vertical beam component into parallel beams respectively. CONSTITUTION:The ion beams whose passing position is regulated by the first grand mask 27 pass through a secondary electron suppressing electrode 28, and injected to the second static deflection system 31 which consists of a y direction deflecting plate 29 and an x direction plate 30. At the y direction deflecting plate 29, a voltage almost synchronous to a y direction scanning plate 22 and of a reverse bias is applied, and the incident ion beams 21 are repelled somewhat in the direction of the center between electrodes of the deflecting plate 29, and made into parallel beams to the y direction. The ion beams 21a are then injected to the deflecting plate 30 in the x direction. To the deflecting plate 30, a voltage synchronous to an x direction scanning plate 23 and of a reverse bias is applied, and made into parallel beams to the x direction in the same manner as the y direction deflecting plate 29. Consequently, an even implanting process of a semiconductive wafer can be carried out.

IPC: F01N3/22
Filed: 1991-06-20
Abstract: PURPOSE:To realize improvement of conversion efficiency of a catalyst and prevention of the thermal deterioration of the catalyst in a compatible manner in an internal combustion engine to supply the secondary air into the exhaust gas. CONSTITUTION:In the partially loaded region of the engine cooling period, a branch passage part 3 is blocked by means of a opening/closing valve 10, and an arrangement is made so that the exhaust gas may reach only from a branch passage part 4 and a fork passage part 6 to a front tube part 7 through a catalyst 9, and may pass through a catalyst 8. Thus, the heat radiating area of the passage parts where the total volume of the exhaust gas passes, is decreased, the heat radiating quantity of the exhaust gas is decreased, the entrance temperature at the catalysts 8, 9 is kept at high temperature even when the secondary air is introduced, and the conversion efficiency of the catalysts 8, 9 is greatly improved. In the higly loaded region after warming up the engine, the opening/closing valve 10 is opened, the exhaust gas flows through all branch passage parts 3, 4 and both fork passage parts 5, 6. This operation increases the heat radiating areas of the passage parts where the total quantity of the exhaust gas for each of the cylinders #1 through #4, and the heat radiating quantity of the exhaust gas is increased, preventing thermal deterioration of the catalysts 8, 9.

Abstract: PURPOSE:To improve the mechanical strength of a polycrystalline fiber by exerting a specific pressure on a crystal at the time of extruding and subjecting the crystal to a heat treatment after molding. CONSTITUTION:The warm extrusion of a polycrystalline fiber 6 is executed by selecting the diameter of a die 1 as desired and using the preform crystal conformed to the diameter of a container for extrusion.

Title: Memory writing circuit
Inventor: YAMAMOTO YUTAKA
IPC: G11C17/00
Filed: 1983-08-12
Abstract: PURPOSE:To increase the writing speed and at the same time to prevent the miswriting to a non-selected memory by providing an auxiliary writing transistor in parallel to a main writing transistor and using these two transistors at the beginning of writing. CONSTITUTION:A high voltage write signal is impressed to the gate of a main writing transistor TR1 while decoder input terminals 22 and 23 are set at high levels and a memory TR3, etc. are selected. Thus the writing is carried out to a memory 3 via the TR1. At the beginning of this writing, an auxiliary writing TR5 connected in parallel to the TR1 via an inverter 30 is also turned on since a source 12 and a drain 11 of TR2 and 3 are set at low potentials respectively. Therefore the writing is carried out at the beginning of writing by TR1 and 5. This increases the writing speed and also suppresses the saturated voltage of the TR3. Thus the miswriting is prevented to a non-selected memory TR4, etc.
