Title: Ink jet head for printer
Inventor: TAKADA NOBORU
IPC: B41J2/16
Filed: 1987-12-24
Abstract: PURPOSE:To prevent the positional deviation or deformation of ink flow paths in a plating treatment or a bonding treatment, by a method wherein inlet and outlet areas corresponding to both ends of respective ink flow paths formed on a flow path plate by etching serve as a half-etched part to be imparted with bonding properties to adjacent support walls. CONSTITUTION:A patterning is applied on a stainless steel plate so that an area of support walls 2' between ink flow paths are coated and ink flow paths 2, a common ink chamber 1, etc. are exposed. At this time, attention is paid so that an inlet area of the ink flow paths 2 branched from the common ink chamber 1 and an area of nozzles 3 corresponding to the outlets of the flow paths 2 are exposed with a small width. Then, a corrosion liquid is sprayed from above it and left to stand for a fixed time, whereby the common ink chamber 1 and intermediate areas of the ink flow paths 2 are corroded with a corrosion liquid at a high speed. On the other hand, the corrosion liquid gradually infiltrates from the exposed part into the nozzle area and the inlet area to form a so-called 'half-etching' part H. Because the ink flow paths 2 are respectively connected with the adjacent support walls 2' by the half-etching part H, a stable positional retentivity is obtained.

Abstract: PROBLEM TO BE SOLVED: To eliminate the need for various filters, to eliminate the labor required for their replacement and to improve the reliability for products by removing various kinds of harmful materials included in raw water by an electrochemical oxidation reduction method and a distillation method.  
     SOLUTION: When the raw water, such as city water, is supplied through a pipe member 24 via an anode inflow port 14 into an oxidation reduction means 10, metals and org. materials included in the raw water are moved heavy to a cathode 13 by the electrochemical oxidation reduction in this means. The heavy metals and org. materials are oxidized to free radical OH at the anode 11 and are reduced to free radical H at the cathode 13. The purified water is made to remain at the anode 11 in such a manner. This purified water is supplied through a pipe member 21 to a storage means 30 and is then supplied to a distillation means 50 where the water is converted to steam by a heater 51. The pure steam from which the org. materials are removed is deprived of the heat by the cooling water flowing in a condensing means 60, by which the steam is condensed and is converted to clean water.

Filed: 1996-11-21
Abstract: PROBLEM TO BE SOLVED: To make the response of a pile and foundation system close to a static state, by sequentially dropping hammers divided into a plurality of parts to a pile head at a constant time interval. SOLUTION: A wire rope 8 is suspended from a hook 3, and insertion holes 7 of divided hammers M1 -MN are passed through a guide shaft 2 to be held by the wire rope 8. he hammers M1 -Mn are held by a fastening tool of the wire rope 8 via a constant distance (d). Then, the hook 3 is released to free the fastening, so that the hammers M1 -Mn are dropped sequentially to collide against a pile head, whereby a load is enervated. The load is measured by a load-measuring instrument 5. A time waveform of the load is obtained. Also a displacement of the pile head is obtained by a displacement gauge 6. The constant distance (d) regulates a fixed time interval of the drop, and therefore a frequency of the load can be controlled as a whole by changing the constant distance (d).  A static supporting force of a pile can be analyzed by analyzing the time waveform of the load and solving an equation of motion. In this manner, a nearly static response of a pile and foundation system can be obtained.
