摘要:
The present invention aims at providing a method and a device therefor which can effectively as well as accurately bury a cable under marine beds not only when a cable is newly laid and buried but also when a cable has to be reburied. The method and the device according to the present invention are characterized in that a burying device is guided to approach the cable by using a travelling member provided on said burying device, a travelling control mechanism thereof being controlled by a receiving output from a transmitter which is mounted on the cable in advance by a receiver provided on the burying device, that the cable is caught and held by a cable engaging member of said burying device while the burying device is detecting the buried cable track and travelling therealong, and that at the same time an excavation member of said burying device digs and forms a groove while the burying device guides and buries the cable within the excavated groove. The method according to the present invention is further characterized in that the burying device is provided with a travelling device which is controlled by the output from a receiver which receives the output from a transmitter on the cable, that said device body is provided at the middle portion thereof with a cable engaging member having a cable engaging mechanism as well as a buried cable route detection mechanism and an excavation member.

An instrument apparatus, includes a tachometer having a chaptering plate provided at a front surface thereof; a display unit arranged at the front surface of the chaptering plate; a printed circuit board arranged at a rear surface of the chaptering plate and driving the display unit. The display unit includes a projecting portion projecting toward the chaptering plate and a male terminal provided at a top end of the projecting portion. The chaptering plate includes an insertion hole formed into a similar shape as an outline of the projecting portion, in which the projecting portion is inserted. The printed circuit board is arranged at a position, in which an insert direction of inserting the projecting portion through the insertion hole and the printed circuit board intersect, and includes a female terminal to be fitted and electrically connected with the male terminal.

Index for use in measuring instruments includes a main body formed with a transparent synthetic resin and having an indicating portion for indicating measured values; a skirt portion formed on the base of the main body with the same transparent synthetic resin as that of the main body and having a hole through which the distal end of an index shaft of a movement element from the measuring instrument is inserted; a balancer disposed on a side opposite to that of the indicating portion and over the skirt portion with a synthetic resin blended with a high specific gravity material for adjusting the balance to the indicating portion; and a cap formed with a non-transparent synthetic resin for covering the base portion of the main body and balancer.
摘要:
A small, highly reliable and inexpensive switching equipment, in which digital signals to be switched, stored as the presence or absence of magnetic domains in a first magnetic sheet or applied as the presence or absence of light to a flat plane formed by bundles of optical fibers, are switched by switching condition determining signals stored as the presence or absence of magnetic domains in a second magnetic sheet.

A method for incinerating material is disclosed wherein a vertical thermal reactor of the fluidized bed type is employed, the reactor being generally a rectangular shape in a horizontal section and having opposed side walls. Fluidizing medium is subjected to different mass flow at the center portion and the side portions so that relatively strong side fluidized beds are formed adjacent the side walls and a relatively weak fluidized bed is formed at the center sandwiched by the side fluidized beds free of any obstructions therebetween. The center fluidized bed tends to descend relative to the side fluidized beds which are deflected at the upper portions thereof, respectively toward the center so that the fluidized medium circulates from the lower part of the center fluidized bed to the lower parts of the side fluidized beds and from the upper parts of the side fluidized beds towards the upper part of the center fluidized bed. The material to be thermally processed is charged to the upper part of the center fluidized bed and pre-shredding of the material is not required.
