Title: Manufacture and device of thermoelectric semiconductor sintered element
Inventor: TAUCHI HITOSHI
IPC: H01L35/34
Filed: 1998-05-20
Abstract: PROBLEM TO BE SOLVED: To minimize a temperature difference between the temperature of thermoelectric semiconductor layer substances and the atmospheric temperature and to prevent the generation of a crack at the time of the formation of the crystal substances by a method wherein the crystal substances are pushed out while being heated to form the crystal substances as continua and these crystal substances are slowly cooled. SOLUTION: A die 14 is filled with thermoelectric semiconductor crystal powder 12 and when the powder 12 is heated up by a plate heater 15 up to 400 deg.C, a pressing force is applied to the powder 12 by a descending punch 16. In this way, thermoelectric semiconductor crystal substances 17, which are used as an N-type thermoelectric semiconductor material, are fed out through an exit 14a formed in the die 14 as continua and the temperature of heaters 21 to 25 is reduced in order so that the substances 17 to pass through a slow cooling unit 20 are cooled at a rate of 0.5 deg.C per one minute. Thereby, the generation of a crack at the time of the formation of the substances is eliminated and the bending strength of the substances can be raised.

Title: Rolling method with plug mill
Inventor: SATO KATSUJI
IPC: B21B17/08
Filed: 1994-06-21
Abstract: PURPOSE:To enable both removal of inside surface flaw and correction of spiral- shaped thickness deviation by using a plug which is used for a 2nd pass, is different in the length of the parallel part from a plug which is used for a 1st pass at the time of elongating/rolling in a plug mill in a method for making tubes with Mnnesmann plug mill. CONSTITUTION:At the time of elongating/rolling a tube stock 1, which is rolled with an elongater after piercing with a piercer, with the plug mill, the inside surface flaw 3 is removed by executing elongating/rolling using the plug 2 having shorter parallel part at a 1st pass.
