Title: Formation method of interconnection
Inventor: HIROTA TAKATOSHI
IPC: H01L21/3213
Filed: 1995-05-17
Abstract: PURPOSE: To obtain a formation method in which the accuracy, the speed and the like of an etching operation are enhanced by a method wherein a metal film which is formed on a substrate is reactive-dry-etched by a mixed-gas plasma of Sil4 and NH3 by making use of an inorganic insulating film as a mask and an interconnection is formed. CONSTITUTION: A mask 16 which is composed of SiO2 (an inorganic insulating film) is formed on a TiN film 15 by an ECR-plasma CVD method. Then, a substrate 11 is placed inside a reactive ion etching apparatus so as to be heated. Sil4 and NH3 are introduced into the apparatus. When a high-frequency voltage is applied in this state, a mixed-gas plasma which is composed of Sil4 and NH3 is generated, and an etching operation is performed by the plasma. As a result of the etching operation, it is possible to obtain an interconnection in a pattern in which the sidewall of a copper film 14, a TiN film 13 and the TiN film 15 is covered with an SiNx film 17 and whose dimensional accuracy is high.

     CONSTITUTION: The required quantity of water is filled up in the sedimentation tank 2 provided  with many inclined plates 1 at multistage style for causing the sedimentation of the sludge; and  the sludge being charged into the sedimentation tank 2 is settled gravitationally. This settling  sludge falls down along the multistage inclined plates 1; when the amount of the sedimentary  sludge on the bottom of the tank 2 becomes the specified amount, the lowest plate 3 is inclinatorily moved so as to partition the bottom zone of the tank 2 into upper and lower rooms cooperating  with the adjoining plates 3; hereby, the partitioned room R 1  is formed between the plate 3 and the  tank bottom 2a. Hereupon, the room R 1  and the room R 2  above the plate 3 are communicated by  the open passage W arranged on one end of the tank 2. Next, the sludge is sucked and discharged  by operating the pump P or the valve V through the sludge pool 4 installed on another end of the  bottom of the tank 2. As a result, the sedimentary sludge existing in the room R 1  is discharged  together with the water of the room R 1  working as the sweeping current.

Title: Two-port saw resonator
Inventor: MORITA TAKAO
IPC: H03H9/145
Filed: 1987-05-15
Abstract: PURPOSE:To obtain a two-port SAW resonator which has small insertion loss and large Q in a high frequency range by specifying the distance between input/ output IDTs with a constant period and reflectors and the distance between input/output IDTs. CONSTITUTION:Input/output interdigital transducers (IDT) electrodes 2 and 3 which have the period L are provided on the surface of a piezoelectric substrate and reflectors 4 and 4' are arranged on both sides of them to constitute the two-port surface acoustic wave (SAW) resonator. Then the distance l1 between the input/output IDTs 2 and 3 are reflectors 4 and 4' is set to mL/2 (m=1, 2, 3...) and the distance l2 between the input/output IDTs 2 is so set that nL/2+L/4<l2<nL/2+3L/8 (n=0, 1, 2...). Therefore, the positions of electrode fingers of the input/output IDTs 2 and 3 are close to the part of loops of a standing wave, so resonance resistance decreases and the insertion loss is improved. Consequently, the insertion loss of the two-port SAW resonator which is stable in the high frequency range is reduced to increase the Q.

Title: Treating of organic waste water containing biologically hard-to-decompose material
Inventor: HORIUCHI ASAO
IPC: C02F1/52
Filed: 1978-09-28
Abstract: PURPOSE: To provide a high degree treatment for stabilized solidification of organic materials and coloring components in waste water, by adding ferric salts to organic waste water containing materials which are biologically hard to decompose and adjusting coagulated sludge under an acidic condition to the range of specific pHs by use of alkali.  
     CONSTITUTION: Biologically undecomposable organic waste water such as biological metabolic deteriorated materials from sewage or drainage is treated by first adding ferric salt such as ferric chloride and ferric sulfate in an amount of 10W1000ppm converted as iron atom. Then, the waste water is adjusted to pH 3W5.5 allowing organic materials and coloring components to be precipitated with flocks of ferric hydoxide. The formed flocks is treated by a coagulant of high molecular weight to produce coagulated solid and separated as sludge. The sludge is adjusted to a pH between 5.5W7 using alkali to permit the organic materials and coloring components to be made insoluble and fixed in high proportion. The process provides thus a simple and cost-effective means to treat organic waste water.

Title: Cylinder liner of engine
Inventor: ISOJIMA HIROAKI
IPC: F02F1/08
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To reduce the cost and improve the adhesion of an insert-casting part by cast molding recessed grooves of a prescribed pitch in multiple stages along the circumferential surface of a cylinder liner. SOLUTION: Recessed grooves 2 of a prescribed pitch P are molded by casting in multiple stages along the circumferential surface of a cylinder liner 1. Accordingly, in the formation of a mold pattern for the cylinder liner 1 by use of a synthetic resin, the mold pattern can be easily formed only by forming the recessed grooves of the prescribed pitch P in multiple stages along the circumferential surface of the mold pattern by a lathe or the like. The recessed grooves 2 can be also formed on the circumferential surface of the cylinder liner 1 at a low cost. Further, since the thickness of the insert casting part can be relatively reduced by the portion having the recessed grooves in insert- casting the cylinder liner 1 into a cylinder block from the viewpoint of the strength against the explosive force of an engine, the cost can be reduced also in this point.  Since the casting thickness of the cylinder block is closely fitted to the recessed grooves of the cylinder liner 1 to closely fit the both to each other, the cylinder liner 1 can be surely prevented from being freely moved in the axial direction.
