PURPOSE:To quicken hooking of the leading part of a thread and thereby lessening amount of the thread to be wasted by allowing a waste thread treatment device to receive the thread end while it is wound round a bobbin in several turns and by cutting the thread between the bobbin and treatment device after overlapping wound threads on the surface of bobbin. CONSTITUTION:Thread 1 under guidance of a...

To obtain a UF foam which is low in formaldehyde, yet is dimensionally stable, up to 96% urea is dissolved in an approximately 10 to 30% aqueous extract of an alkyl, aryl or alkaryl sulphonic acid, said solution being mixed with a conventional hardener/foaming agent solution containing the sodium salt of an alkyl, aryl or alkaryl sulphonic acid in an aqueous diluent usually employed for foaming, i...

In a foam extrusion appts. of the type in which the extrudate is extruded into a sloping vacuum chamber, the end of the chamber is closed by concentric bulkheads movable to and from the closure position. The outer bulkhead carries a shaping mechanism while the inner bulkhead carries the die. The die is connected via a bellows-like device to a tube, itself connected to an extruder and also movabl...

PURPOSE:To exactly recognize a CPU subsystem, by providing a system information storage part for storing each self-subsystem discriminating information of the CPU sybsystem, and sending out as a response the contents of said storage part from the CPU connected by a connecting device. CONSTITUTION:A response system of each host system 1, 2 is constituted by providing plural CPU systems N1, 01, N2 a...

PURPOSE:To ensure a release via the initial program for the resetting device of the multi-computer device for vehicles which incorporates several units of the electronic computers, by resetting the computers when the input of the faulty computer changes from the L level to the H level. CONSTITUTION:If the electronic computer 20 has some faulty working, the rise time duration becomes longer than th...

PURPOSE:To obtain a metallic pipe with a non-oxidized internal surface by pressurizing a mandrel into a billet disposed in a container from one end thereof toward a die to extrude a metallic pipe, and pressurizing the billet to close its end while the mandrel is removed from the forming hole in the end period of the extrusion. CONSTITUTION:A mandrel 7 is press fitted into a billet 5 disposed in a ...

A method for retreading vehicle tires. A carcass is provided with a prevulcanized tread and an unvulcanized tie-gum layer between the carcass and tread. A microwave applicator is located above the tread for emitting microwaves to the tire for creating heat energy in the tire. A reflector for microwaves comprising an electrically conductive material is attached in connection to or in the tie-gum la...

An apparatus and method for cold retreading of the running surface of a vehicle tire. A rubber and cloth mold is produced utilizing a new tire male mold covered with perforated polyethylene film, uncured rubber and highly stretchable cloth enclosed in an envelope and cured by application of pressure and heat. The somewhat flexible female mold thus produced is then utilized in recapping tires by po...

PURPOSE:To attempt to reduce the size of an ink jet printer by such an arrangement wherein the number of transistor to be installed in a drive circuit is reduced by using only one transistor for charging piezoelectric elements. CONSTITUTION:Print head units A, B are connected in parallel to a charge and discharge unit 1 having a transistor Tr1 for charging which is a common switching element. The ...

PURPOSE:To obtain an ink jet head requiring no axle-matching between an ink discharge port and an air discharge port provided in front of the ink discharge port by a method in which the ink discharge port is made up of a group of fine openings. CONSTITUTION:An air nozzle plate 2 provided with an air-discharge port 1 is set in parallel with an ink nozzle plate 3. Air is sent in from peripheral port...
