Title: Production of polyethylene terephthalate composite film
Inventor: OKUYAMA KATSUMI
IPC: B32B27/08
Filed: 1990-02-01
Abstract: PURPOSE:To enhance bond strength between a modified ethylene-vinyl acetate copolymer (EVA) film and a polyethylene terephthalate (PET) film and heat- bonding properties of a composite film for other materials, by using the modified EVA film as a heat-bonding layer, treating a surface of the modified EVA film to be brought into contact with the PET film by corona discharge, and pressing the two films against each other at a temperature not lower than the melting temperature of the modified EVA. CONSTITUTION:In laminating a PET film with an ethylene resin film used to serve as a heat-bonding layer, a surface of a modified EVA film to be brought into contact with the PET film is treated by corona discharge, and the two films are pressed against each other at a temperature not lower than the melting point of the modified EVA. The PET film is molded from a PET having a basic skeleton composed of ester linkages formed by a condensation reaction between terephthalic acid and ethylene glycol. The modified EVA film is molded from a modified EVA obtained by modifying an EVA having a vinyl acetate content of 4-30wt.% by, for example, grafting to the EVA an unsaturated carboxylic acid or anhydride thereof, such as maleic anhydride.

Title: Variable static flow type fuel injection device
Inventor: ASANO HITOSHI
IPC: F02M51/06
Filed: 1990-01-31
Abstract: PURPOSE:To enlarge practical injectable flow from the minimum flow to the maximum flow by increasing/decreasing the passage sectional area of a fuel measuring part on the basis of the position switching of a stopper so as to obtain both small and large flow characteristics with one fuel injection device. CONSTITUTION:When the stopper face of a stopper 58 is opposed to the stopper facing part 60 of a valve member 22 to give a small flow stroke to a valve member 22, a valve side measuring part 44 corresponds to a body side first measuring part 54 in the movement of the valve member 22 in the opening direction so as to form a fuel measuring part of small passage sectional area by both parts. A small flow characteristic sufficiently low in the lowest practical value of injection flow can be thereby obtained. On the other hand, when the stopper face is moved into a receding position from the stopper facing part 60 by a stopper moving means 70, the valve member 22 is provided with a large flow stroke, so that the valve side measuring part 44 corresponds to a body side second measuring part 56 in the movement of the valve member 22 in the opening direction.

Abstract: PURPOSE:To prepare the titled compound useful as a feed additive, etc., easily, in high yield, economically in an industrial scale, by reacting glycine with acetaldehyde in the presence of a catalytic amount (less than equivalent to glycine) of a copper compound. CONSTITUTION:The objective compound can be prepared by reacting glycine  with acetaldehyde and an alkaline substance (e.g. NaOH) in the presence of less  than equivalent amount (based on glycine) of a copper compound (e.g Cu2O) in  a proper solvent at room temperature -100 deg.C, and precipitating and removing  the copper compound used as a catalyst from the reaction system after the reaction by passing hydrogen sulfide gas into the reaction liquid thereby converting  the copper compound to copper sulfide. EFFECT:Since the amount of the copper compound is catalytic, the removal of copper can be carried out easily compared with the conventional process. The yield of the threo-compound is essentially the same as the case using equivalent amount of the copper compound.

Title: Kana to kanji conversion correcting system
Inventor: KAMEDA MASAYUKI
IPC: G06F17/22
Filed: 1990-01-31
Abstract: PURPOSE:To reduce the burden of a user by executing the selection from a small number of candidates instead of such a troublesome work as adjustment of delimiter length in the case of correcting a conversion error caused by an error of a delimiter at the time of KANA (Japanese syllabary) to KANJI (Chinese character) conversion. CONSTITUTION:In the case a user corrects an error of a converted KANA/ KANJI mixed character-string at the time of KANA to KANJI conversion, as for candidates whose delimiting method to a KANA character-string of an object is the same, only one candidate is shown as its representative instead of the display of a list of all the candidates of the KANA/KANJI mixed character-strings of different delimiters. For instance, in the case as a result of KANA character conversion of (-)ku - ru - ma - de - wa - ko - o - ha - ko - bu(-), it is desired to correct to (-)kuru - made - wa ¦ko - o¦ hakobu(-) (child is carried until coming) instead of (-)kuruma - de ¦hako-o¦ hakobu(-) (¦box¦ is carried by car), each candidate group is contracted to one candidate, respectively as shown in a candidate list of two figures. In such a way, the burden for selection by a user reduced.

Title: Frequency offset compensator
Inventor: OKUBO YOSHIYUKI
IPC: H03D3/06
Filed: 1996-01-17
Abstract: PROBLEM TO BE SOLVED: To provide an offset compensator with which power required for operating a phase compensation value can be reduced without lowering accuracy for the compensation of phase error. SOLUTION: This device is provided with a phase compensating means 9 for compensating the phase error caused by the frequency offset of detected received data while using the phase error compensation value, discriminating means 10 for performing quadrant discrimination to the output of the phase compensating means 9, and phase error estimating means 4 for estimating the phase error from the value of correlation between detected received data and quadrant discriminated data and outputting the phase error compensation value to the phase compensating means 9.  In this case, the phase error estimating means 4 respectively accumulates a correlative value S'.D calculated for each symbol between complex conjugate data S' of detected received data S and an output D of the discriminating means 10 and the complex multiplied result |S|<2> between the received data S and their complex conjugate data S' for N symbols and operates a phase error compensation value ψ' for every N symbols while using these accumulated values. Since the phase error compensation value ψ' is calculated not for each symbol but once N symbols, power consumption is reduced.

Title: Manufacture of urethane foam having no surface skin
Inventor: MURAKAMI SHINICHI
IPC: B29C39/26
Filed: 1979-02-28
Abstract: PURPOSE: To prevent formation of a hard and smooth surface skin on the surface of urethane foam, by using a hydrophilic or water-holding mold-releasing agent and a hydrophilic or water-holding urethane foam compound containing a large amount of superfluous water.  
     CONSTITUTION: After forming a film of hydrophilic or water-holding mold-releasing agent 6 on mold surface 4, urethane prepolymer having hydrophilic or water-holding bond and a hydrophilic or water-holding urethane foam compound containing a large amount of superfluous water are subjected to foam molding. Since the surface of urethane foam is held in contact with mold-releasing agent 6, a large amount of condensed water leaching out from urethane foam is absorbed promptly into mold- releasing agent 6, and at the same time, gases such as carbon dioxide gas and steam are also drawn into the agent 6, so that condensed water and bubbles are produced at a high concentration near the surface of urethane foam. Therefore, the surface of urethane foam thus produced is not flat but it remains in a rather rough state, so that surface skin is not formed.
