Title: Reflection type projecting device
Inventor: WATANABE KOHEI
IPC: G03B21/00
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To prevent a projected image from being adversely influenced by the soiling of a reflection mirror and to improve the quality of the projected image by providing a light scattering plate by which the depth of field is made shallow on an optical path between a projection lens and a DMD(digital micro- mirror device) element. SOLUTION: The light scattering plate 20 is arranged on the optical path between a condenser lens 4 and the DMD element 5 in this device. Thereby, parallel beams (incident light) from the lens 4 are scattered and radiated to the DMD element 5, so that the incident angle of the light to a screen 7 gets large and the depth of field is made shallow. Even when this device is used as the projector of a rear projection type display, the projected image is prevented from being influenced by the soiling or the distortion of the reflection mirror and video quality is improved.

Inventor: HASHIZUME RON
IPC: C11B3/06
Filed: 1989-02-15
Abstract: PURPOSE:To readily remove a large amount of free fatty acids mixed in fatty acid esters by adding a concentrated alkali solution to a fatty acid ester solution containing a solvent having a specific dielectric constant as a solvent, precipitating alkali soaps of the free fatty acids, filtering and fractionating the resultant fatty acid esters. CONSTITUTION:A solvent (e.g. hexane, acetone, ethanol, methanol or methanol/ water mixture solution) having 1.8-75 (preferably 1.8-55) dielectric constant as a solvent is added to raw material fats and oils containing free fatty acids and a concentrated aqueous solution of an alkali is then added and stirred to form and precipitate alkali soaps of the free fatty acids. The resultant soaps are subsequently cooled to 4-10 deg.C to sufficiently form precipitates. The alkali soaps are then separated by filtration to distill away the solvent from the obtained filtrate. Thereby, fatty acid esters in which the free fatty acids are removed are obtained.

IPC: G05F1/56
Filed: 1980-03-19
Abstract: PURPOSE:To erase a specific harmonic current running on an AC power supply side without use of a filter by connecting two single-phase bridge rectifiers in series and controlling their cintinuity angle in a special order and at a special phase angle. CONSTITUTION:Rectifiers 5, 6 are connected to an AC power supply 1 through a transformer 20 using an element such as GTO, etc. The DC sides of the rectifiers are connected in series to supply an electric power to a load 8. In addition, the continuity angle of one rectifier is controlled at a bypass operation mode for an interphase angle alpha2-alpha1, at rectifier operation mode for between alpha1-pi+alpha2, while the continuity angle of the other rectifier is controlled at a rectifier operation mode for between -alpha2-pi-alpha1 and at a bypass operation mode for pi-alpha1-pi-alpha2. At the same time, alpha1, alpha2 are selected in such manner that coskalpha1 + coskalpha2 = 0 may be satisfied against the degree K of a power supply harmonic current. Consequently, it is possible to completely erase a specific harmonic on the power supply side only by controlling a rectifier itself without use of a filter.
