Title: Far infrared heater
IPC: H05B3/10
Filed: 1992-03-31
Abstract: PURPOSE:To provide a far infrared heater having a deodorizing function in addition to a heating function by connecting the deodorizing capsule powder containing specific powder on the surface of a heating section to form a deodorizing layer. CONSTITUTION:The powder of tungsten is joined into a cylindrical shape by the plasma sintering method to form a heating element 1. A radiator 3 made of insulating silicon oxide and radiating far infrared rays to its surface is formed to constitute a heating section 4. A deodorizing layer 5 made of the deodorizing capsule powder by the plasma sintering method is formed on the surface of the radiator 3. Particles of a noble metal or a rare earth oxide having the grain size of several mum or below are joined on the surfaces of mother particles of zeolite, alumina, or silica to form the capsule powder. When the heating element 1 is excited and heated, the deodorizing layer 5 is heated, the adsorbed malodorous constituent is oxidation-decomposed and regenerated, and the deodorizing function is exerted.

Title: Current supply type thermal transfer printing head
Inventor: SONEHARA HIDEAKI
IPC: B41J2/32
Filed: 1988-03-30
Abstract: PURPOSE:To reduce the adverse effect of the surface roughness and undulation of a heat-resistant insulating substrate or the roughness of paper on image quality, by forming a heat-resistant resin layer between the heat-resistant insulating substrate and a recording electrode. CONSTITUTION:A heat-resistant resin such as a liquid polyimide resin is applied to a heat-resistant insulating substrate 1 and heat-treated to form a heat- resistant resin layer 2. Thereafter, recording electrodes 3 are formed. Since the heat-resistant resin layer 2 reduces the surface roughness of the heat- resistant insulating substrate and is extremely soft as compared with a conventional glaze layer 4, the recording electrodes 3 are made easy to adapt to the unevenness of paper or the warpage possessed by the heat-resistant insulating substrate itself to improve the close adhesiveness of the electrodes to a film or a paper and the adverse effect of these elements on image quality is reduced.

Abstract: PURPOSE:To obtain a system converter appropriate for making into IC and allowed to be reduced at its size and cost in respect to a device for converting a TV system signal such as an HDTV signal, etc., having many scanning lines into a TV system signal such as an NTSC signal having small scanning lines. CONSTITUTION:The scanning lines of an input signal are thinned by a scanning line conversion part 3a provided with a small capacity speed conversion memory 4a to convert the input signal into a squeeze mode signal. In the case of converting the squeeze mode signal into a wide mode, the scanning lines of the signal converted into a squeeze mode is furthermore thinned by a scanning line conversion part 3b to convert the signal into a wide mode signal. Thereby an MN converter can be constituted of only one IC without requiring the addition of a large capacity speed converting memory 4b in respect to a purpose only for the squeeze mode and the MN converter for a purpose requiring the wide mode also can be constituted only by externally connecting the memory 4b. Consequently this system converter is appropriate for IC formation and its size and cost can be reduced.

Title: Phase shift-adaptive damping method in active damping system
Inventor: MICHLER JAMES R
IPC: F16F15/02
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To secure stable operation of an active type damping device with an effective phase shift-adaptive control. SOLUTION: An active damping system 10 uses the phasor technique suited to an excessive phase shift of constituting elements of the system and uses an optimum control technique for determining a preliminary value of a model of a controller. The preliminary coefficients are scale-processed so as to indicate the difference of a unit, and the scale-processed coefficients are used for determining a phase angle and the relative size of the phasor. Relating to the respective components of control force to a tuned mass 24, respective phasors are suited to already known phase shift in the system and displaced so as to hold the same relative size of the phasor relating to the respective components.  A phase shift coefficient value is scale-processed so as to return the coefficient to an original unit, the coefficients are used in the controller, command signals are generated and external force 28 for adjustment is added to the tuned mass 24.
