IPC: B65D30/22
Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To enable storing substances to be mixed in a securely separated state and make the mixing easy to carry out when two substances are mixed. SOLUTION: In this bag for preservation 11 a first substance 35 and a second substance 36, which are to be mixed, are kept in a bag body 12 in a separated state and the two substances 35, 36 are mixed at the time of use. In this instance the part 12A to hold the first substance 35 and the part 12B to hold the second substance 36 are separated from each other by a biting means 13 of the watertight type in structure and a biting means 14 of the biting strength maintaining type. For example, the use of ammonium nitrate as the first substance 35 and water as the second substance 36 has a cooling effect when the two substances 35, 36 are mixed.

Title: Intake throttle valve opening detecting device for internal combustion engine
Inventor: SATO HISAAKI
IPC: G01B7/30
Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To detect the opening of an intake throttle valve for an internal combustion engine at high accuracy by coping with variations of sensors and a change with the lapse of time. SOLUTION: The correlation between the elapsed time from the time when an intake throttle value is full opened and to the time when it is totally closed by valve closing energizing force and the opening is previously stored as the reference characteristic. The opening is changed from the full opening to the total closing in learning, and the correlation (sensor characteristic) between a detected signal of an opening sensor and the elapsed time is monitored.  When the time from the full opening to the full closing in the reference characteristic is taken as tv0 , and time from the full opening to the total closing in the sensor characteristic is taken as ts0 , the time ts on the sensor characteristics is set to satisfy the expression: tv =ts .tv0 /ts0 and converted into tv on the reference characteristic, and the correlation between the detected signal and the opening is learnt by making the detected signal the time ts and the opening at the time tv corresponding to each other.

Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To ensure electrical reliability and reduce capacitance between wirings, by enabling to form a low permitivity film while preventing generation of peeling on the surface of a substrate film. SOLUTION: Before forming an organic system low permitivity film 5 whose relative permitivity is lower than an SiO2 film 3 on the surface of the SiO2 film 3 as a substrate film having an Si-O bonding, a modified film 4 is formed on the surface of the SiO2 film 3. Formation of the modified film 4 is performed, e.g. by irradiating the surface of the SiO2 film 3 with a light having a wavelength which can cut the Si-O bonding on the surface layer of the SiO2 film 3 or with ions. Before formation of the low permitivity film 5, an adhesive film composed of CF based polymer generated from plasma may be formed on the surface of the SiO2 film 3.

Title: Method for double molding and mold therefor
Inventor: KAMEI YASUHIKO
IPC: B29C39/28
Filed: 1989-01-13
Abstract: PURPOSE:To prevent burr from developing at double molding by a method wherein a projection, which determines a surface layer part is provided either on a secondary mold or on a core material part so as to seal the cavity of the surface layer hermetically by bringing the projection in near line contact with the rest in order to pour surface layer material in the cavity of the surface layer part of the secondary mold and cure the material. CONSTITUTION:A projection 32, which determines the limiting position of a surface layer part, is provided on a core material 26 so as to determine the cavity 38 of the surface layer part by bringing in near line contact with the top surface 36a of the cavity. That is, the cavity 38 of the surface layer part is sealed hermetically without being effected by the molded state of a core material part. In addition, the surface layer material poured in the cavity 38 of the surface layer part is cured without leaking from the cavity 38 so as to be molded integrally to the outer peripheral surface of the core material part 26. As a result, burr due to the leakage of the surface layer material at secondary molding can be prevented from developing, resulting in improving the exterior quality of a double molded item. Further, since the removal work of barr in finishing process can be omitted, the simplification of working processes of the double molded item is made possible.

Abstract: PURPOSE:To enhance the accuracy of a pattern by controlling voltage accelerating ion beams for removing residue in accordance with data on errors of the dimensions of a pattern due to back scattering in the exposure of a resist with electron beams. CONSTITUTION:A resist film 3 is exposed by irradiation with electron beams 4 through a prescribed pattern and developed to form a patter of the resist film 3. After the development, the residue 5 of the resist film 3 remains on a metal layer 2 in a thinly distributed state. In order to remove the residue 5, the entire surface of the metal layer 2 including the pattern of the resist film 3 is successively irradiated with ion beams 6. Voltage accelerating the ion beams 6 is controlled in accordance with the dimensions of the pattern of the resist film 3 designed in consideration of data on the relation between the designed dimensions of the pattern of a photomask and errors of the dimensions of the pattern by the effect of back scattering of electron beams. The residue 5 is removed and simultaneously the dimensions of the pattern of the resist film 3 are corrected.
