Abstract: A transmitting terminal can transmit a content held by itself to a specific receiving terminal having no email software as if using a mailer. The transmitting terminal (10) and the receiving terminal (20) are connected to a delivery server (30) via a network (4). The delivery server (30) comprises: a database (36) for registering the device ID that specifies the receiving terminal (20); a content storage (39) for temporarily storing a content transmitted from the transmitting terminal (10); and table (33, 37) for managing contents separately on a per device ID basis of the receiving terminal. The delivery server (30), when receiving a request from the receiving terminal (20), refers to the tables (33, 27) and transmits to the receiving terminal (20) a content, the transmission destination of which corresponds to the device ID of the receiving terminal (20).

Abstract: A closed type connecting block including a shutter which close and open an opening formed on a housing and which is biased toward a position to close the opening. The shutter and the housing are formed with notches which sealingly receive a core inserted into the connecting block therebetween. The connecting block also includes a pivotable jack mounted therein to enable users to easily insert and remove a plug connected to the cord from communication equipment.

Abstract: A connecting block for electrically connecting a plug of a telephone set to a telephone line includes a base plate having a terminal for connection to the telephone line, a jack unit including a jack having an opening for inserting the plug thereinto, the jack unit having parallel side walls across the jack opening, a pair of parallel retaining members extending upwardly from side edges of the base plate for removably retaining the jack unit therebetween, and a cover for enclosing the retaining members, the jack unit and the terminal, the cover having a window to which the jack opening may be exposed. The arrangement of the jack unit and the retaining members is such that the jack opening may selectively extend parallel to the base plate or perpendicular thereto.

Abstract: Fluorine or fluorine compounds dissolved at low concentrations in water are efficiently separated by use of hydrated rare earth oxides or insoluble hydrated rare earth salts, particularly hydrous rare earth fluorides or hydrous rare earth phosphates, as the adsorbent. By bringing fluorine dissolved water of pH 2-7 into contact with said adsorbent, fluorine is adsorbed on the adsorbent, and the adsorbed fluorine can be desorbed by contact with an alkali solution of pH 10 to 14 to regenrate said adsorbent. Also, by addition of a precipitating agent for fluorine to the desorbed solution, fluorine compounds can be separated by precipitation and the filtrate can be reused as the regenerating solution for the adsorbent.

Abstract: Borate ions dissolved at low concentration in water are separated efficiently with the use of a hydroxide or hydrous oxide of a rare earth element as the adsorbent. By contacting a borate ion-containing water with the absorbent, borate ions are separated by adsorption, and the adsorbent having adsorbed borate ions is desorbed and the regenerated for reuse with a desorbing solution adjusted to pH about 2 to about 4 or pH about 12 to about 14.

Abstract: In a process for the separation of elements by chromatography in which a front zone and a rear zone are present in front of and in rear of an adsorption band of elements, a high column efficiency can be attained by developing the adsorption band of elements without causing the entry of a main eluent having a relatively high concentration into the front zone. According to the present invention, elements can be separated into individual species not only in a high state of purity but also in a high state of concentration, so that the productivity of elements may be extremely increased as compared with that of conventional methods. In addition, according to the present invention, the amount of eluent employed is remarkably small as compared with that in conventional methods. Therefore, the present invention is very advantageous for the separation of elements from an industrial standpoint.

Abstract: Aquatic animals can be kept in a living condition over a long period of time, without feeding them, by placing the aquatic animals, at a large density of more than 200 kg/m.sup.3 in environmental water; maintaining the temperature of the environmental water in a lowest possible range in which it is possible for the aquatic animals to exist; controlling the concentrations of ammonia compounds, water-soluble organic compounds and carbonic acid radical in the environmental water so that their levels do not exceed 20 ppm, 150 ppm and 1,000 ppm, respectively; and regulating the concentration of molecular oxygen dissolved in the environmental water so that it is 3 ppm or more.

Abstract: An acrylonitrile polymer film is produced by the steps of:Extruding an acrylonitrile polymer solution in a tubular shape into a coagulation liquid bath while a coagulation liquid is introduced into and withdrawn from the inside of the extruded tubular-shaped film;Removing the solvent remaining in the coagulated tubular film, and;Biaxially stretching the tubular film containing 5 to 23% by weight of water based on the dry weight, at a temperature of 100.degree.-170.degree. C. at least twice its original length both in the longitudinal and transverse directions by a tubular stretching procedure.

Abstract: A net-shaped outer blade for reciprocating type electric shaver having an improved new pattern of hair inlet holes is provided. In a metal lamina as the outer blade body, a number of hair inlet holes including slit-shaped and round-shaped types is formed between adjacent ones of a plurality of ribs which are spaced at a proper interval with continuously varying spacing. The length dimension of the hair inlet holes is varied thus depending on the varying spacing between the ribs, and their lengthwise direction is made the same with each other. The area of the respective holes is advantageously made substantially equal to one another.
