Title: Regulating circuit of inductive load current
Inventor: PIETORO MENICHI
IPC: H02P7/00
Filed: 1990-03-28
Abstract: PURPOSE: To reduce the power consumption with a simple constitution and to surely detect an induced current by giving a driving potential to a terminal on the gate side of a first transistor TR through an electronic switch in the case that the electronic switch is in the close state. CONSTITUTION: When an induced current is generated in a load, this current is transmitted to the non-inverted input terminal of a comparator 3 corresponding to a detection circuit. The comparator 3 detects the rise of the potential of the non-inverted input terminal of the comparator 3 to send a comparison signal to an electronic switch 4 so that the switch 4 is set to the close state. Therefore, the electronic switch 4 is set to the close state, and the driving potential is given to the gate side of a first TR T2 from a driving stage 5a through the electronic switch 4, and the first TR T2 is made conductive to make the induced current generated in the load escape to, for example, the ground. Consequently, the induced current is made escape, and the induced current can be controlled.  Thus, the power consumption is reduced with the simple constitution, and the induced current is surely detected.

Title: Treatment of silicon nitride-based ceramic material
Inventor: TAKAYANAGI YUTAKA
IPC: C04B35/584
Filed: 1996-04-01
Abstract: PROBLEM TO BE SOLVED: To provide a method for treating an Si3 N4 -based ceramic material which is difficult to be crush processed, by heating the Si3 N4 -based ceramic material coexisting with a specific material at a prescribed temperature for converting the ceramic material into a glass material so as to be able to treat as a waste material. SOLUTION: This method for treating a silicon nitride-based ceramic material is to heat the Si3 N4 -based ceramic material coexisting with preferably a material for supplying V selected from a V compound, a mixture of V compound and a diluent, a mixed material containing V and a boiler ash containing V (e.g.; V2 O5 with Na2 SO4 as a diluent) at a temperature of >=900 deg.C, preferably >=1,200 deg.C. Although, the Si3 N4 -based ceramic material is a material high in high temperature strength and corrosion resistance, the material is strongly corroded by V. For example, by making a contact of Si3 N4 with V at a high temperature, Si3 N4 decomposes to yield N2 , and then residual Si becomes SiO2 to form a glass. Therefore, this method is effective for a waste material treatment of Si3 N4 -based ceramic waste material.
