Title: Junction method of semiconductor substrate
Inventor: SAKANO SUSUMU
IPC: H01L21/31
Filed: 1987-02-23
Abstract: PURPOSE:To junction two or more sheets of silicon substrates, by superposing two or more silicon substrates with thin oxidizing films and heating them at a prescribed temperature. CONSTITUTION:A P type silicon substrate 1 and a N type silicon substrate 2 are superposed and held in a helium gas 5 which is an inactive gas and heated by a heater 6. Thereupon, O2 atoms in thin oxidizing films 3 and 4 are diffused into substrates 1 and 2, and the films 3 and 4 disappear.

Title: Detector for imbalance in current
Inventor: HAYASHI SHINICHIROU
IPC: H02H3/36
Filed: 1978-04-04
Abstract: PURPOSE: To accomplish immediate detection of imbalance in current of the feed circuit by checking current of the tertiary winding of the transformer with the primary and secondary windings opposite in polarity thereof connected to the end of a paralled feed circuit having a switching element in series.  
     CONSTITUTION: One end of the primary and secondary windings 9 and 10 connected opposite in polarity of a transformer with the tertiary winding (CT) 13 is connected to resistance 3 and 4 of a switching circuit having transistors (TR) 1 and 2 connected thereto in parallel. The iron core of CT 13, for instance, employing a ring core, is wound with the tertiary winding to form an output terminal 11 while primary and secondary windings 9 and 10 equal in the number of turn are inserted in the opposite direction through the hole of the core and connected to the power connection wire as shown in the drawing. With such an arrangement, when either of TR1 or TR2 fails, one of fuses 5 and 6 is shut off thereby developing the open state, which changes the ampere pattern of the primary and secondary windings 9 and 10. The output voltage thus yielded in the tertiary windings enables immediate detection of  imbalance in the current of the switching circuit.

Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To provide a pulse sound detecting method of which estimation of a background noise level is correctly carried out even in the case of sudden rise of the background noise. SOLUTION: A pulse component detection processing part 11 compares instant power input from a instant power computation processing part 3 with a threshold input from a threshold computation processing part 6 so as to detect the pulse components, outputs them to an output control processing part 13, and outputs the number of the detected pulse components to a control processing part 12. The control processing part 12 judges three cases, the case of no existence of pulse, the case of existence of pulse, and the case of sudden change of background noise, based on the number of pulse components input from the pulse component detection processing part 11, and hence controls a background noise level estimation processing part 5 and the output control processing part 13.  The output control processing part 13 does not output the instant power and the frequency information of the background noise to an output terminal 7, based on the judged results of the three conditions from the control processing part 12.
