摘要： PURPOSE:To prevent received data sounds from being outputted in the case of starting transmission by changing tone transmission timing on the transmission side corresponding to a tone detecting time length on the reception side. CONSTITUTION:A tone frequency to be used by a transmitter is fA, the tone detecting time of a receiver is T1. On the side of the transmitter, control is executed so as to send the transmitting tone before T1 hours (T2) after the end of transmitting data. When the tone frequency to be used by the receiver is changed from fA to fB, the tone detecting time T1 of the receiver is changed and therefore, corresponding to this change, control is executed so that the transmitter side can send the transmitting tone before changed T1 hours (T2) after the end of transmitting data transmission. As the result, the received data tones are not outputted as sounds when starting the output of sounds from the receiver.

摘要： PURPOSE:To mold a stable disacetylene monomolecular adsorption built-up film by forming a silane monomolecular adsorption film on any substrate and allowing an aliphatic monomolecular film to be coupled to the monomolecular adsorption film using an oxidation coupling reaction method. CONSTITUTION:A silane surfactant with an acetylene bond in a molecule is allowed to undergo reaction, using a chemical adsorption method, on an Si substrate 1 with SiO2 formed on the surface to form a monomolecular adsorption film 2. Next, a long-chain aliphatic acid with an acetylene bond in the molecule is allowed to undergo reaction on the monomolecular adsorption film 2 using an oxidation coupling method to form a built-up film 5 as the second layer. Thus, for instance, a diacetylene bond 6 is formed on the surface of the adsorption film 2. Again the silane surfactant is allowed to undergo on the surface of the built-up film 5 to form a built-up film 8 as the third layer with the help of a chemical adsorption method. After this, if an energy ray 11 such as far ultraviolet ray is cast to the whole surface of the built-up film, the diacetylene bonds 6 are polymerized with the adjacent other and subsequently, a highly stable diacetylene monomolecular adsorption built-up film is formed.

摘要： PURPOSE:To produce highly efficiently an ultrahigh-MW linear polydiacetylene having a succession of conjugated systems, by polymerizing a monomolecular film of a diacetylene derivative cast on the surface of water by irradiation with light under a specified surface pressure. CONSTITUTION:A diacetylene substance dissolved in an organic solvent is cast on the surface of water and the organic solvent is evaporated from the solution. The molecules of said diacetylene substance left on the surface of water are gathered with a barrier on the surface of water in the direction of the surface of water and polymerized by irradiating with light under a specified surface pressure. The above process makes it possible to make a liner ultrahigh-MW polydiacetylene having a succession of conjugated systems because the compression of the diacetylene molecules arranged in a state of separate molecules by a constant pressure can eliminate gaps formed from the molecular shrinkage during photopolymerization and thereby keeps conditions necessary for the photopolymerization reaction of the diacetylene monomer. By applying a DC bias to the reaction system in the direction of the surface in performing the photopolymerization, the orientability of monomer molecules can be improved and a polydiacetylene of a longer conjugation system can be made.

摘要： PURPOSE:To conserve manufacturing time, to lower material cost and labor to a large extent, by a method wherein the surfaces of the water having the first and second monomolecular films are formed in a separated state within a water tank and a rotary body is interposed between both surfaces of the water to successively build up the monomolecular films on a plurality of the substrates mounted on said rotary body. CONSTITUTION:A plurality of substrates 11 such as semiconductive wafers are mounted on the rotary surface of a rotary body 3. The surface of the water in a water tank 1 is divided into two surface-of water parts 14, 15 by a support rod 5 and monomolecular films of long chain fatty acids respectively different in a chemical formula are formed. In the first and second surface-of-water parts 14, 15, the rotary body 3 is rotated from the air to the water or from the water to the air in a predetermined direction to transfer the monomolecular films to the substrates 11. By this method, by changing the rotary direction of the rotary body 3, the number of rotations thereof or the kinds of the materials to be used for the monomolecular films, the kinds of the built-up films or the built-up number thereof can be easily controlled and the monomolecular built-up films are formed on a large number of the substrates within a short time.

摘要： PURPOSE:To improve an error rate, transmission efficiency and a transmission rate by encoding a digital receiving signal in order of sampling, comparing the past value and the latest value of encoded data and detecting whether a self-correlation of a receiving signal exists or not. CONSTITUTION:Registers 5-7 hold successively 8-bit data (Dn-1), (Dn-2), and (Dn-3), respectively in order of arrival from a CPU 3. In such a state, when a CPU 3 outputs the latest data (Dn), the holding contents of each register 5-7 are transferred successively to the next stage, and also, the output data (Dn-3) of the register 7 is compared with the data Dn by a comparing means 9 through an inverting means 8. When a coincidence is obtained by the means 9, a counting value of a counting means 10 is increased by one, and when a coincidence is not obtained, the value is decreased by one. When this counting value is >=3, it is decided that a sampling signal in that case is a preambld signal. In such a way, the preamble signal can be detected surely in an early stage, and a receiver of good transmission efficiency and a high transmission rate is obtained.

摘要： PURPOSE:To produce the title monomolecular built-up film by irradiating a first monomolecular film of a silane surfactant formed on the surface of a substrate with a high-energy beam in a specified gas atmosphere, and thereby forming the chemically combined second monomolecular film. CONSTITUTION:The oxygen and silane surfactant on the surface of a hydrophilic substrate 1 are chemisorbed in a nonaqueous org. solvent to form the first monomolecular film 3 of the silane surfactant on the surface of the substrate 1. The film 3 is irradiated with a high-energy bean in a specified gaseous atmosphere, or the silane surfactant is chemisorbed after plasma treatment. As a result, the second monomolecular film chemically combined with the film 3 is formed on the film 3, and a monomolecular built-up film 7 is obtained. A chemical substance shown by CH2=CH-(CH2)n-Sicl3 [(n) is an integer] is appropriately used as the silane surfactant.

摘要： PURPOSE:To improve the reliability of the vapor deposition type magnetic recording medium and to realize high-density recording by forming plural layers of monomolecular films consisting of silane surfactants on the surface of a magnetic recording layer formed by vapor deposition on a medium substrate as protective films. CONSTITUTION:The magnetic recording layer 2 is formed by a sputtering method, etc., on the disk substrate 1 for magnetic recording. Plural layers of the monomolecular films are formed as protective films 8 by a method of alter nately executing, plural times, a stage of forming one layer of a monomolecule- adsorbed film by chemical adsorption of the silane surfactant to a monomolecu lar state and a stage of denaturing the sensitive group of the activating agent by executing irradiation of energy rays such as electron rays on X-rays or plasma treatment in an atmosphere contg. O2 or N2. The high-density thin org. film is thereby formed on the surface of the medium with a uniform thick ness without having the pinholes and further, lubricity is provided to the medium surface by incorporating F into the surface, by which the slipperiness of the head is improved.
