In the maintenance of a ring-type local area network, the physical number, physical addresses and connection sequence of nodes in the network can be readily made known without need of any management by system control personnel. To this end, a frame which can be discriminated only by the immediately succeeding station is used, and own addresses are successively set in an information field of the frame to convey the status of physical connection to the succeeding stations.

Dental materials using calcium phosphate glass-ceramics and having the color tone with high approximation to that of natural teeth. In those dental materials, calcium phosphate composite, nickel oxide and one or more other type of compounds selected from oxides of iron, manganese, cerium, titanium and tungsten, are contained as coloring component. Also, if necessary, Al.sub.2 O.sub.3 and/or SiO.sub.2 is contained as a color assisting agent in that composite. The calcium phosphate glass-ceramic according to this invention consists of the same components as that of natural teeth. Besides, it is possible to adjust the color tone delicately to match with the color tone of each individual`s teeth. Moreover, the coloring components are incorporated in crystals of calcium phosphate. Consequently, they cause no elution during use and are therefore ideal as dental material.

The disclosure is related to a method for removing crude oil sludge, which is convenient for removing sludge while the crude oil is transported. The method for removing crude oil sludge from crude oil includes the steps of:(a) classifying grains of sludge into coarse grains and small grains;(b) settling the sludge in the crude oil discharged from the classification step to separate the coarse grains from the crude oil;(c) sending the crude oil which is the supernatant constituent in the settling step to a filter in order to separate the remaining sludge in the crude oil; and(d) introducing a part of the above crude oil to a reverse washing liquid inlet of the filter, in order to wash reversely the filter medium of the above filter.

A solid state image pick-up device includes a number of picture elements arranged in a matrix form each picture element being constituted by a MOS transistor and a photodiode, gates of the MOS transistors arranged in a vertical direction are connected to respective horizontal scanning lines which are connected to outputs of a horizontal shift register. Drains of the MOS transistors arranged in a horizontal direction are connected to respective vertical scanning lines both ends of which are connected to first and second signal read-out lines via first and second vertical selection switches, respectively. The first and second vertical shift registers produce first and second vertical scanning pulses which are shifted by given time period corresponding to a desired shutter open time. Each picture element is scanned twice by means of the first and second vertical scanning pulses. By adjusting said time period, the shutter open time can be set at with within a wide range.

In a structure for removably mounting a support rod for an openable closure member such as engine hood, trunk lid or the like of a motor vehicle, a retainer member of a plastic material is mounted on at least one end of the support rod, and an anchor member of a plastic material which is adapted for engagement with the retainer member, is mounted in a mounting aperture formed either in the vehicle's body or the openable closure member. By virtue of the engagement between the retainer member and the anchor member, the support rod is removably retained with respect to either the vehicle's body or the openable closure member, thereby supporting the openable closure member at its open position.

An optical amplifier particularly for use in a high data-rate fibre-optics communication link utilizing a body of a dielectric substance transparent to signal light of a given band of wavelengths and transparent also to pumping light of a different band of wavelengths, a smooth continuous surface along the length of the body having as amplifying component a layer of laser material adhered contiguous to the surface. Both signal light and pumping light are introduced into an end face of the body, which may be a passive dielectric fibre core such as glass, or a passive dielectric slab with parallel side walls, utilising mode order converting holograms. By the phenomenon of penetration by light of both frequencies within a thin layer of the adhered material as the light beams undergo multiple total internal reflections at the interface between the body and the laser material, atoms of active material, e.g. Nd.sup..sup.+ 3 or organic dye molecules in the laser medium are optically pumped to a higher energy level, and fluoresce and are stimulated by the evanescent-wave component of the signal light to coherently emit light in a band of wavelengths correlated with the signal band of wavelengths. The amplified signal light is delivered from the other end face, and is launched through further hologram devices in a transmission mode into a succeeding fibre or slab of the link.

A proof information processing apparatus adds a plurality of types of annotative information to a proof image by use of a plurality of input modes for inputting respective different types of annotative information. A proof information processing method is carried out by using the proof information processing apparatus. A recording medium stores a program for performing the functions of the proof information processing apparatus. An electronic proofreading system includes the proof information processing apparatus and a remote server. At least one of input modes including a text input mode, a stylus input mode, a color information input mode, and a speech input mode is selected depending on characteristics of an image in a region of interest which is indicated.
