摘要： PROBLEM TO BE SOLVED: To provide a mold which modifies an arbitrary part of the surface of molding at the time of molding a thermoplastic resin, and also to provide an injection molding apparatus and a sealing mechanism. SOLUTION: This mold for injection molding has a fixed mold and a movable mold forming a cavity together with the fixed mold, where the mold has a built-in gate-forming member which communicates with a gate, introducing a thermoplastic resin into the cavity, with the cavity and interrupts the gate, and the gate-forming member has a gate seal positioning member integrally driven with the gate-forming member. The gate-forming member is independently driven with respect to the movable mold, and the relative distance of the gate-forming member from the fixed mold is kept constant regardless of opening amount of the cavity by virtue of the gate seal positioning member.

摘要： PROBLEM TO BE SOLVED: To provide an information recording member and a recording/ reproducing device stably recording and reproducing in a short time in the information recording member making both or a land part and a groove part formed on a substrate surface a recording track recording information. SOLUTION: A substrate is used wherein the land part 2 and the groove part 1 appear alternately along the recording track, and the switching points A of the land part 2 and the groove part 1 exist by the number shown by a following relation per one round of the recording track. The relation is made 2m-1 (m: 1, 2, 3...). Thus, since the land part 2 and the groove part 1 are formed alternately on one round of the recording track, continuous recording and reproducing to both of the land part and the groove part become possible without track jumping between the land part and the groove part, and a recording time and an access time are reduced.
摘要翻译：要解决的问题：为了在信息记录部件中在短时间内稳定地记录和再现信息记录部件和记录/再现装置，使得形成在基板表面上的两个或一个焊盘部分和凹槽部分成为记录磁道记录信息。解决方案：使用基板，其中岸台部分2和槽部分1沿着记录轨道交替显示，并且岸台部分2和凹槽部分1的切换点A以每一轮的以下关系所示的数字存在的录音轨道。关系为2m-1（m：1,2,3 ...）。因此，由于陆部2和槽部1交替地形成在记录轨道的一圈上，因此在陆部和槽部之间没有轨道跳跃的情况下，能够对陆部和槽部两者进行连续的记录和再现，并且记录时间和访问时间减少。

摘要： PROBLEM TO BE SOLVED: To provide a method for molding a polymer having a minute uneven pattern of a high aspect ratio in high shape accuracy and a polymer molding molded by the method.
SOLUTION: In the polymer molding method, a supercritical fluid in which a monomer is dissolved is introduced to be in contact with a polymerization initiator set on a substrate to polymerize the monomer. For example, by arranging the substrate in a mold in which the fine uneven pattern is formed at a position opposite to the substrate, the supercritical fluid containing the monomer intrudes into the pattern so that the monomer is polymerized/molded according to the pattern.

摘要： PROBLEM TO BE SOLVED: To provide a method for modifying the surface of a polymer such as thermoplastic resin, using supercritical fluid, especially carbon dioxide in a supercritical state as a solvent and for making the polymer surface highly functional in a short time. SOLUTION: In the method for modifying the surface of a polymer, a dissolved substance is made to permeate into the surface of the swollen polymer by previously applying the dissolved substance to the polymer surface, when the supercritical fluid comes into contact with the polymer. Thus it is possible to realize the permeation of the dissolved substance into the polymer in a short time and in a highly concentrated state. COPYRIGHT: (C)2006,JPO&NCIPI
