Abstract: PROBLEM TO BE SOLVED: To provide a method for laying an underground pipeline which simplifies an operation for construction and is excellent in the properties of construction. SOLUTION: A method for laying an underground pipeline wherein a pipeline is laid afresh in the ground. In the ground between one manhole Q1 and the other manhole Q2 wherein a fresh pipeline is to be laid, a tunnel is formed beforehand by a method of non-cut-and-cover propulsion and a wire is pulled into the tunnel. A long reduced pipe 1 of which the shape is changed so that a sectional contour area is reduced in a state wherein a performance of recovering a shape of a cylindrical body at shape memory temperatures is given thereto is used as a material for forming the pipeline, and the long reduced pipe 1 is laid in the ground by connecting the fore end of this pipe to one end part of the wire 3 in one manhole Q1 and by pulling the other end part of the wire 3 from the other manhole Q2.  Then the long reduced pipe 1 is heated to the shape memory temperatures from inside and thereby an almost original shape of the cylindrical body is recovered. This cylindrical body is expanded thereafter by air pressure from inside in a state of the heat being left therein and then it is cooled with air and fixed.

Title: Paper feeding method for printer
Inventor: TAKEMURA HIROFUMI
IPC: H02P8/22
Filed: 1982-11-26
Abstract: PURPOSE:To feed paper of more than one kind of speed at a high efficiency with limited number of pulses by switching the excitation of a stepping motor according to the paper feeding speed. CONSTITUTION:When an ordinary density switch 6 and a medium density switch 7 are operated, a 2-phase excitation pulse train generator 3 is selected to cause a 2-phase excitation of a stepping motor 2 for feeding paper while it is switched over to 1-2 phase excitation by operation of a high density switch 8. For example, when the vertical density of a character is set at 12, 18 or 36 dots in the ordinary, medium or high density, it is necessary to input 3 and 2 pulses into the motor 2 in the ordinary or medium density as obtained by dividing the least common multiple 36 of 12 and 18 as number of dots by the number of dots. On the other hand, in the case of 1-2 phase excitation, as compared with the 2-phase excitation, the step angle of the motor 2 will be down to a half and it is necessary to input 3 pulses into the motor 2 in the same number of pulses as that in the ordinary density. This enables the feeding of the paper of more than one kind of speed at a high efficiency with limited number of pulses as compared with the use of a 2-phase excitation alone.

Title: Choke coil for magnetron
Inventor: YOKOSE YOSHIKAZU
IPC: H01J23/15
Filed: 1985-09-19
Abstract: PURPOSE:To enable high-frequency operation of a magnetron by winding two coils around a single core in such a manner that they have overlapping inductances for an in-phase current and contradicting inductances for a differential current. CONSTITUTION:Each of choke coils 7a and 7b consists of a winding 7 which is formed by bundling four enamel wires 7-1-7-4. The choke coils 7a and 7b are wound around a core 6 in such a manner that magnetic fluxes (phia) and (phib) produced by the coils 7a and 7b overlap each other for an in-phase electric current (Ic) (the noise current of a magnetron) and contradict each other for a differential current (Id). Due to the above structure, the skin effect of the choke coils 7a and 7b of the magnetron caused by a high frequency current is reduced and inhibition of the thermal radiation of the filament resulting from temperature increase is alleviated, thereby preventing any decrease in the life of the magnetron. Furthermore, it is possible to facilitate operation of the magnetron at high frequency in order to inhibit the noise current and prevent any reduction of the current of the filament.
