IPC: B01J35/02
Filed: 2002-08-15
Abstract: <P>PROBLEM TO BE SOLVED: To provide a titanium oxide-apatite composite material which has adsorption force and photocatalytic oxidation power and can be semi-permanently used as a catalyst or an antimicrobial agent.  <P>SOLUTION: The titanium oxide-apatite composite material consists of titanium oxide and apatite composited by hydrothermal reaction. The production method for the titanium oxide-apatite composite material comprises subjecting apatite and a water-soluble titanium compound to hydrothermal reaction. The production method may further contain a step for producing apatite by the hydrothermal reaction of phosphoric acid and calcium carbonate. The titanium oxide-apatite composite material may be produced by the hydrothermal reaction of phosphoric acid, calcium carbonate, and a water-soluble titanium compound. Thus, for example, the titanium oxide-apatite composite material comprising fine titanium oxide particles deposited on and adhered to apatite paticles is obtained.  <P>COPYRIGHT: (C)2004,JPO

IPC: B41J2/045
Filed: 2002-08-28
Abstract: <P>PROBLEM TO BE SOLVED: To reduce power loss in a load drive circuit such as a drive circuit for piezoelectric elements in an ink jet head.  <P>SOLUTION: A load drive circuit comprises drive elements (M1 to M4) for driving capacitive loads (CL1, CL2), and a voltage control circuit (6). The voltage control circuit is for controlling the supply voltage waveforms of the drive elements when the capacitive loads are charged, and controlling the supply voltage waveforms of the driving elements when the capacitive loads are discharged. The voltage control circuit controls the waveforms so that they become gentler than the curve of a change in the terminal voltage of the capacitive loads when a rectangular voltage waveform is given to a series connection circuit of the capacitive loads and the drive elements. Thus, energy lost in resistance elements connected in series with the capacitive loads is reduced. As a result, reduction in power loss in the load drive circuit is attained.  <P>COPYRIGHT: (C)2004,JPO
