Patent JP-H04105180-A (JP)
Title: Differential amplifier
Inventor: MIYANO NAOYA
IPC: H03F3/45
Filed: 1990-08-24
Abstract: PURPOSE:To obtain a differential amplifier with variable mutual conductance by inputting voltage to a differential amplifying transistor and making the mutual conductance changed from the time of inputting. CONSTITUTION:When power source voltage is given to a power source terminal VDD, when ground voltage is given to a ground terminal VSS and when voltage to be differential-amplified is given between input terminals V1 and V2, the input voltage is differential-amplified so that the one of output terminals V10 and V20 may be low in the case the other is high. Mutual conductance gm of an differential amplifier is increased as time elapses after the voltage to be differential-amplifier is given to the input terminal V1 or V2. That is, the gm can be changed during a period when the differential amplifier differential amplifies. Thus, the differential amplifier that the gm changes during an amplifying action can be obtained.

Title: Ultraviolet-intercepting agent
Inventor: TAKAGI OSAMU
IPC: A61K8/00
Filed: 1996-08-07
Abstract: PROBLEM TO BE SOLVED: To obtain an inorganic ultraviolet-intercepting agent highly able to intercept ultraviolet rays and excellent in transparency by using titanium phosphate microparticles having a specified means particle diameter. SOLUTION: This agent comprises a titanium phosphate having a means particle diameter of 0.1μm or below, desirably a compound having a Ti/P atomic ratio of 0.5-1.5. Especially, titanium phosphate having a Ti/P atomic ratio of 0.8-1.0 possesses an excellent ability to intercept ultraviolet rays and excellent transparency and therefore is a desirable compound. When the titanium phosphate has a Ti/P atomic ratio smaller than 0.5 or larger than 1.5, there is the possibility of lowering the ability to intercept ultraviolet rays. Desirable examples of the titanium phosphates include Ti(OH)PO4 , TiPO4 and Ti(HPO4 )2 .  This agent is excellent in both the ability to intercept ultraviolet rays and transparency, so that it is used as, for example, a modifier for ultraviolet- intercepting coatings used for, e.g., windowpanes of a high-rise building or an automobile or also as a cosmetic additive because of its safety and good spread on the skin.
