Patent JP-H08226645-A (JP)
Title: Combustion device
Inventor: YASUDA AKIHIKO
IPC: F23N5/20
Filed: 1995-02-20
Abstract: PURPOSE: To secure the safety of usage and enhance the advantage of usage as well by setting a continuous combustible time period of a burner to a short time proportionally as the accumulated time of unburnt gas concentration detection time accompanied by the continuous combustion of the burner becomes longer and setting similarly as well as the concentration of the unburnt gas becomes higher. CONSTITUTION: A continuous combustion time of a burner 2 is integrated with a combustion time integrating means 102 and an accumulated time of detection working time of an unburnt gas concentration detection means 10 is measured with an accumulated time measurement means 101. Furthermore, a combustion time setting means 104 is adapted to set a setting time separately for each of the setting ranees in terms of a detected value of the unburnt gas concentration detection means 10, thereby shortening the setting time as the accumulated time is more increased and shortening the setting time as the concentration of the unburnt combustion gas is increased based on detection information of the unburnt gas concentration detection means 10.  When an integrated time by the combustion time integrating means 102 exceeds the setting time equivalent to the detected value of the unburnt gas concentration detection means 10 at that time, the combustion of the burner comes to a halt.

Abstract: PURPOSE:To remove an electrical leakage wave by constituting a filter so that electric signals applied to two reed screen electrodes are made a negative-phase-sequence to each other, and also surface elastic waves made by the respective reed scrren electrodes are made same as above.

Filed: 1990-02-13
Abstract: PURPOSE:To dice a semiconductor substrate without corroding an exposed wiring on the substrate, by providing a rotary edge, an acid water solution nozzle and a basic water solution nozzle. CONSTITUTION:Acid cooled water wherein CO2 of 50ppm or less is dissolved and basic cooled water wherein NH3 of 50ppm or less is dissolved are jetted under a high pressure from a nozzle 3a and a nozzle 3b respectively to a part of contact of a substrate 1 with a diamond cutter 2.
