Title: Pressure-sensitive adhesive composition
Inventor: MAEDA MASAYOSHI
IPC: C09J133/04
Filed: 1983-06-17
Abstract: PURPOSE:To provide a pressure-sensitive adhesive compsn. having good storage stability and exhibiting excellent adhesive properties, prepd. by adding a specified crosslinking agent to a specified functional acrylic copolymer. CONSTITUTION:The adhesive compsn. is prepd. by adding polyglycidyl m-xylylenediamine as crosslinking agent to a functional acrylic copolymer obtained by polymerizing a monomer mixt. consisting mainly of a 2-8C alkyl ester of acrylic acid (e.g. n-butyl acrylate) and contg. 0.1-10wt% vinyl compd. with an active hydrogen atom capable of reacting with the glycidly group, e.g. (meth)acrylic acid. Acrylic pressure-sensitive adhesive is superior to rubber-based pressure sensitive adhesive, but adhesive varnish made from conventional acrylic pressure sensitive adhesive compsn. has poor storageability. Addition of the crosslinking agent gives a pressure-sensitive adhesive compsn. having excellent storage stability and strong cohesive force and adhesiveness.

Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To provide the adjustment device for a temperature compensation crystal oscillator in which dispersion in each temperature characteristic of respective crystal vibrators and frequency deviation due to temperature in adjustment is absorbed. SOLUTION: In this method, a crystal oscillator provided with a trimmer 2, a crystal vibrator 3 whose temperature characteristic is printed by a bar code 6 and a storage device 4 is adjusted to have a specified frequency and the temperature at that time is measured by a non-contact thermometer 11 of a frequency adjustment device 10 and the measured temperature is written in the storage device 4. A bar code reader 21 reads the temperature characteristic of the crystal vibrator and selects optimum temperature compensation data from pluralities of temperature compensation data stored in advance in a temperature compensation data write device 20. Furthermore, a frequency deviation between a temperature at the adjustment and a standard temperature is calculated and the temperature compensation data including the frequency deviation are stored in the storage device 4.  The temperature characteristic of the crystal oscillator is compensated on the basis of the temperature compensation data corrected with the frequency deviation.

Abstract: PURPOSE:To avoid the clogging in a gas flow channel thereby enabling the fluctuation in gas concentration during the removal process to be detected stably without the with-time detrioration by a method wherein, within the title organic matter removing device provided with the means of ashing an organic matter, picking up and analyzing a produced gas by a particle removing means as well as detecting the terminal of the removing process, a temperature control system is arranged in the gas flow channel from a produced gas intake to a gas leading-in port of the particle removing means. CONSTITUTION:A filter 11 arrests the particles such as organic matters contained in an exhaust gas to prevent them from depositing on the inner surface of piping or the gas flow channel part of a sensor. However, the gas produced by ashing process in the atmosphere at 150 deg.C-300 deg.C is cooled down in the gas flow channel reaching the filter 11 so that the gas flow channel may be clogged by a part of produced gas set and deposited by thermal condensation. A temperature control system 21 can control the temperature in the gas flow channel to let the gas run into the filter 11 without thermal condensation.

Abstract: PURPOSE:To make sure joining and to reduce the time for joining by imposing an annular brazing filler metal to the flared step part of the 1st refrigerant pipe then fitting the end of the 2nd refrigerant pipe into said part and heating the flared part of the 1st refrigerant pipe. CONSTITUTION:The annular brazing filler metal 3 is imposed on the flared part 1 of the 1st refrigerant pipe 2 and the end of the 2nd refrigerant pipe 4 is fitted therein. The extreme end 1b in the flared part of the pipe 2 is heated simultaneously on both sides by a 2-nozzle burner, etc. The brazing filler metal 3 is melted to spread over the entire surface between both pipes 2 and 4 and begings to overflow from the spacing. The molten brazing filler metal cools to solidify and the pipes 2, 4 are joined when the heating of the burner is stopped at this time. The metal 3 is thereby uniformly melted to reach to the entire surface in the spacing between the pipes 2, 4 and therefore the joining by brazing is made sure and the joining time is reduced.
