Title: Semiconductor diode circuit
Inventor: NISHIMORI HISAO
IPC: H01L29/732
Filed: 1998-12-11
Abstract: PROBLEM TO BE SOLVED: To suppress a current flowing in a substrate through a parasitic transistor, without increasing the transistor size by providing an element for increasing the voltage drop between the base and collector of a PNP transistor, thereby lowering the potential at a contact between the base line and the collector line. SOLUTION: In this semiconductor diode circuit, an element comprising a resistor R for increasing a voltage drop is connected between the base and collector of a PNP transistor Q1 constituting a semiconductor diode, and an element for increasing the voltage drop between the base and collector of the PNP transistor Q1 uses a diode, an external resistor or an NPN transistor. Thus the potential at the contact between the base line and the collector line can be lowered due to the voltage drop, and the leakage current to the substrate can be suppressed, without increasing the transistor size.

Inventor: TAKAHASHI TATSUTO
IPC: C04B28/02
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To provide a stone material used for sinking and disposing the stone material in water, capable of exhibiting excellent functions in the fields of the imbedding and growth of aquatic plants, the breeding of fishes and shellfishes, and the purification of water and not causing troubles such as the pH elevation of sea water, etc., and the generation of white precipitates, when the stone material is sunk and disposed in the water for uses such as alga banks, fish banks, river beds or water purification. SOLUTION: This stone material contains a material containing non-carbonated Ca (excluding slag) or its mixture with slag as a main raw material, and is prepared by coagulating and caking the powder and/or granules of the main material with a binder comprising CaCO3 produced by the carbonation reaction of the non-carbonated Ca mainly contained therein. Since most of the non-carbonated Ca contained in the main raw material of the stone material is changed into CaCO3, the elevation of pH in sea water, etc., due to the non-carbonated Ca can be prevented. Since the whole body of the stone material is porous, the surface of the stone material facilitates the adhesion of sea algae.  Further, since ingredients which are effective for the promotion in the growth of aquatic plants and are contained in the stone material are easily eluted in water, the growth of the aquatic plants can be promoted.
