Title: Punch press
Inventor: KATO FUMIO
IPC: B21D28/36
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To prevent entanglement of scraps between a die and a die holder at a die exchanging time by equipping a die holder with an air spraying means for removing scraps clogged between the die and the die holder. SOLUTION: Plural air spray nozzles 51 are installed on a top inner face of a die holder 41, and air is sprayed towards an inclined upward direction (arrow C direction) having an appropriate angle against a center direction of a die D. A circular resin hose 55 is installed as a circular supply path to an upper peripheral part of the die holder 41, and air is supplied to the circular supply path from an air supplying source. When a work is punched by a punch mold and the die D, scraps are retained at a groove portion M and are blown off by the air from the air spray nozzles 51. When the die D is exchanged, a bottom turret 15 is rotated so as to calculate the position of the die D, and the die holder 41 is rotated by a worm wheel 49 so as to position the die D and the die holder 41 at an original position. Thereby, air supply paths 57A and 57B are linked.

Abstract: PROBLEM TO BE SOLVED: To prevent a tube element from disengaging from a tank temporarily by simply engaging the tube element with a notch formed in a partition even at a step where assemblying of the core of a heat exchanger device is already completed, but brazing is not yet started. SOLUTION: A groove 7 is formed along a joining portion of a pair of molded plates 4, 4 at an extremity of a connecting opening of a tube element 2. A protrusion 16 which is inserted in the groove 7 under pressure is formed on a tube-element abutting portion 17a of a notch 17 of a partition 11 which constitutes a part of a tank. The sides of the notch 17 are shaped so as to expand gradually from an opening end side to a tube element abutting side corresponding to an expanding direction of the connecting opening 5 of the tube element 2.  Due to such a construction, when the tube element 2 is fitted into the notch 11 of the partition 11, the protrusion 17 of the notch 11 is forcibly inserted in the groove 7 of the connecting opening portion of the tube element 2 and expands the groove 7 so that the connecting opening portion 5 of the tube element 2 is expanded and forcibly brought into contact with the sides of the notch 17.

Abstract: PROBLEM TO BE SOLVED: To provide a method for producing hydroxymethylcyclopropane useful as an intermediate for a bactericide, a fungicide, a herbicide and an insecticide by catalytically hydrogenating a formylcyclopropane.  
     SOLUTION: Formylcyclopropane is hydrogenated by using zinc chromite, copper chromite and/or a copper/zinc catalyst at 20-250°C under 10-350 bar pressure to produce the objective hydroxymethylcyclopropane. Especially, the optimum temperature of the catalyst at the hydrogenation is respectively 180-220°C in the case of the zinc chromite, 30-50°C in the case of the copper chromite and 80-150°C in the case of the copper/zinc. The objective hydroxymethylcyclopropane is obtained from a easily available starting material in a high yield and selectivity. An after treatment of the hydrogenated mixture is reduced because no alcohol is formed.
