Title: Production of porous ceramics
Inventor: IZUMI MASAAKI
IPC: C04B38/00
Filed: 1993-02-16
Abstract: PURPOSE:To easily and efficiently produce a porous ceramic material having high porosity and relatively high strength and containing mutually interconnected pores having large diameter. CONSTITUTION:A ceramic slurry containing ceramic powder, a binder and a dispersion medium is frothed to introduce bubbles into the slurry and the foamed material is formed and baked. When a ceramic slurry incorporated exclusively with a binder and a dispersion medium, etc., commonly used in forming is forcedly stirred without using a porosifying agent to introduce a number of bubbles into the slurry, the introduced bubbles, i.e., the cavities have diameters of several hundred mum to several mm and, accordingly, remain even by the progress of sintering at a high temperature to easily obtain a porous ceramic material having high porosity and large pore diameter. Since a high- temperature baking can be carried out in the process of this invention, the sintering locally proceeds to obtain a porous ceramic material having relatively high strength for high porosity.

Title: Switch circuit using semiconductor
Inventor: KATAYAMA KAZUNARI
IPC: H03K17/60
Filed: 1980-03-03
Abstract: PURPOSE:To make it possible to control the A type load by small-sized transistor, as well, by connecting in parallel an output circuit of an output transistor, a small resistor and an A type load  (load which has connected an incandescent lamp and a capacitor with load in parallel), and connecting said small resistance and the constant-voltage device in parallel. CONSTITUTION:When the A type load 7 is being operated perfectly, the voltage drop of the resistance 8 is set a little lower than the voltage of the constant-voltage device 1, therefore the  transistor 3 holds such a stable state as perfect on. As for a convertional switch circuit, at the  starting time when the switch is turned on, in case of an incandescent lamp, a current of about  >=10 times as large as that which is in the course of perfect operation flows and a large-sized  transistor which is can withstand a current exceeding said one is required. In this case, when the  voltage drop of the resistane 8 by the current in perfection operation is made almost equal to the  voltage of the constant-voltage device 1, a starting current of about >=10 times as large as that at  the time of switching on can be suppressed to the perfect operation current value, and also the current at the time of perfect operation is not influenced at all, therefore the output transistor 3 for  controlling an incandescent lamp can be changed to size of 1/10 of a conventional one, and the A  type load can be controlled by a small-sized transistor, as well, accordingly.
