Title: Continuous extrusion apparatus for foamed body
Inventor: ARAGAI TAKESHI
IPC: B29C48/53
Filed: 1979-01-25
Abstract: PURPOSE:To form high-magnified and uniform foamed body by arranging so that gas does not flow in a direction of either metal mold or raw material feed port under a device to intermittently close foaming agent injection port with one point of the screw shaft. CONSTITUTION:Raw materials such as polyethylene, etc. are fed into supply region 9 through raw material feeding port 5, and are fed into the kneading region 12 after heating and melting, while gradual compression is caused to take place from the feed region to the first compression region 10 and the first measurement region 11. In the kneading region, screw shaft 21 is eccentrically disposed. Consequently, as the screw is rotated, the foaming agent injection port 6 is closed by the accentric shaft part 21, interrupting the feed of foaming agent. In this way, foaming agent is intermittently fed and blended. In addition, its injection pressure is interrupted by screw shaft 21 and screw flight 3, thus preventing the outflow of foaming agent from the metal mold or the flowback to the raw material feeding port 5.

Title: Input and output controller
Inventor: ITO KEIICHI
IPC: G06F11/07
Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To shorten the investigating time of a communicating state between a peripheral equipment and a host system, and to facilitate a countermeasure to plural host systems. SOLUTION: A CPU 50 allows an FPGA(Field Programmable Gate Array) 58 to generate a prescribed trace logic circuit, and allows a channel control part 60 to start communication with a host system. The channel control part outputs a channel sequence number 78 through a buffer 62B to the FPGA 58. The FPGA 58 stores a channel interface signal 76 and a channel sequence number 78 in a prescribed timing. When an error is generated in communication, the CPU 50 detects the cause of the error based on the channel interface signal 76 and the channel sequence number 78. When it fails, the detection of the cause of the error is repeatedly operated by allowing the FPGA 58 to generate another trace logic circuit.

The screw thread of the nut 2 is pressure-bonded to the screw thread of the bolt 1 by caulking the caulking part 4 of the nut 2 screwed to the bolt 1. As a result, a clearance between the screw threads of the nut 2 and the bolt 1 is eliminated in the normal screwing state, and a possibility in which the nut 2 is loosened is eliminated.

Title: Sound field analyzing method
Inventor: SERIKAWA MITSUHIKO
IPC: G01H17/00
Filed: 1983-01-20
Abstract: PURPOSE:To reduce sharply the volume of data and a calculation time by dividing a space to be analyzed into two, and making element division uniform in an area including a sound source and gradually rough in an area distant from the sound source. CONSTITUTION:The closed space inside an imaginary outside boundary 2 provided encircling a structure 1 which includes the sound source in an infinite space is the space to be analyzed. An imaginary inside boundary 3 divides the space to be analyzed into the area 4 including the sound source and the area 5 distant from the sound source. A discrete equation is solved for sound pressure P in the area 4 as it is, so element size in element division is limited to the extent that at least variation in one wavelength is followed up. Further, the sound pressure P is expressed in the area 5 as the product of a function showing a spherical wave and a function P for correcting deviation and a discrete equation is solved for the correcting function P.

IPC: C23C18/28
Filed: 1994-01-28
Abstract: PURPOSE:To improve adhesion strength of a Cu-plating layer to the surface of a polyimide resin film by including a step of treating the film with an alkali metal oxide soln. after the film surface is etched in the process of Cu plating on the surface of the film. CONSTITUTION:After the surface of a polyimide resin film is cleaned, the surface is etched, to which a catalyst for electroless plating is added and activated. A plating layer of Ni, Co or alloy of them is formed by electroless plating on the surface activated with the catalyst. The electroless plating layer is activated by heating in an inert gas atmosphere and subjected to electroplating with Cu. In this process, after pretreatment of the polyimide resin film by etching, such a step is added that the film is treated with an alkali liquid containing 0.1-5 mol/l density of alkali metal hydroxide such as NaOH or KOH at 10-50 deg.C. Thus, adhesion property of the Cu electroplating film to the polyimide resin film is significantly improved.
