Filed: 1982-02-12
Abstract: PURPOSE:To improve the feeling of usage, by increasing a rising temperature only with the switch operation at an arbitrary time. CONSTITUTION:A transistor (TR) 33 is set on when an AC power supply 1 is not in zero cross state, and a TR32 is set with pulses at the zero cross of the AC power supply by the operation of the TR33. Thus, a current flows to the primary winding of a pulse transformer 30 instantly only at the zero cross of the AC power supply to induce the said current to flow to the secondary winding of the pulse transformer 30. A gate current is impressed between (G) and T1 terminal of a triac 58 only at the zero cross of the AC power supply via a diode 59, and the triac 58 is conducted with the 100% of conduction angle. Since a TR47 is set off in this case, a base current is impressed to the base of a TR20 via resistors 45, 46, the TR20 is set on and a variable resistor 19 is kept in electrical short-circuit.

Title: Rutile-type colored fine-grain titanium dioxide composition and its production
Inventor: IWANE NOBUO
IPC: C01G23/047
Filed: 1989-01-30
Abstract: PURPOSE:To obtain the composition colored rose-brown, shielding selectively UV and capable of being easily dispersed in an aq. dispersion medium by coating the grain of titanium dioxide with specified amts. of Al, silica, iron oxide or iron hydroxide by coprecipitation. CONSTITUTION:The surfaces of the titanium dioxide grains having <=0.1mu maximum grain diameter are coated by coprecipitation with 1-10wt.% (based on TiO2) of each of the aluminum, silica, and iron oxide or hydroxide expressed in terms of Al2O3, SiO2 and Fe2O3 to obtain the desired fine-grain titanium dioxide composition. The maximum grain diameter is controlled to <=0.1mu, because the hiding property due to the reflection of the visible light beam is caused or the transparency is lost when the grain diameter becomes more than the half-wave length of the visible light beam. Although transparency is theoretically kept at <=0.19mu, the transparent feeling is somewhat lost by the access effect or the aggregation of the grains.
