A document presentation device comprising an imaging unit that takes images of documents and a display unit that displays the images of documents taken by the imaging unit.

Document presentation device including a movable part

A presentation system comprises a display for setting a virtual screen, a pointing mark for operating a point on the display, a photographing device for photographing the pointing mark and the display, a displaying device for displaying a predetermined image or the photographed image photographed by the photographing device, and a control device. The control device calculates coordinates of the pointing mark on coordinates of the virtual screen and has a pointing function for synthesizing a predetermined point image at coordinates of the image on the displaying device, which correspond to the coordinates of the pointing mark.

Presentation system, material presenting device, and photographing device for presentation

A presentation system comprises: a screen device; a projecting device for projecting an image onto the screen device; an indication mark for setting two reference points, which is two orthogonal points on a rectangular virtual screen, near a presenter and for the presenter operating a point on the virtual screen; a photographing device for photographing the virtual screen and the indication mark; and an arithmetic operation device for generating coordinates of the virtual screen from the two reference points photographed by the photographing device, and for calculating coordinates of the indication mark on the generated virtual screen. The projecting device projects a point image onto the coordinates of the indication mark on the image.

Presentation system

A presentation system for a presenter to safely point out parts of an image projected from a projector onto a screen with laser light projected from a laser pointer held by the presenter is disclosed. The presentation system includes one or more infrared light receiving units on the laser pointer that selectively receive infrared signals from sending units that are mounted on the projector or on walls in order to control emission of laser light from the laser pointer. Arrangements of the sending and receiving units are designed to allow emission of the laser light from the pointer only when the laser pointer is pointed toward the projection screen. A control unit in the laser pointer may determine if the laser pointer is pointed correctly or a gravity operated shutter may further assist in preventing unsafe projection of laser light from the laser pointer.

A glycol-based coolant composition which provides an excellent metal corrosion inhibition despite its low phosphorus content is disclosed. The glycol-based coolant composition contains: (A) 0.1-5.0% by weight of at least one ingredient selected from group A&prime; consisting of C6-C12 aliphatic dibasic acids and their alkali metal salts; (B) 0.1-10% by weight of at least one ingredient selected from group B&prime; consisting of alkyl benzoic acids and their alkali metal salts; (C) 0.001-0.1% by weight of at least one ingredient selected from group C&prime; consisting of strontium compounds and their alkali metal salts; and (D) 0.1-0.3% by weight of at least one ingredient selected from group D&prime; consisting of phosphoric acids and their alkali metal salts.

Low P type coolant composition

A negative film carrier for driving a negative film in a longitudinal direction of the negative film to convey the film to a printing position, is provided with a bar code reading mechanism. In the mechanism a light emitting element on one for illuminating the bar code is disposed to face one side surface of the film, and a light receiving element is disposed to face the other side surface thereof. These elements are mutually separated when the film is inserted between them in the widthwise direction of the film at the printing position. At the time of film transporting condition these elements are linked together to unitedly move and follow the edge of the film so as to accurately coincide with the bar code.

Film carrier

Two optically active amino acid-mandelic acid complexes are obtained by interacting in a solvent under pH conditions of 1.0-4.0 an amino acid expressed by a general formula ##STR1## (in which R represents a methyl group, an ethyl group or a methylthioethyl group) and mandelic acid, one of the acids being an optically active substance and the other being a racemic modification, and optically resolving the resulting complexes into two diastereoisomers by using solubility difference therebetween. The optically active complexes are each decomposed by means of an acid, a strongly acidic ion-exchange resin, or a weakly basis ion-exchange resin to obtain optically active amino acids or optically active mandelic acid.

Process for preparing optically active amino acid or mandelic acid

Two optically active amino acid-mandelic acid complexes are obtained by reacting in a solvent under pH conditions of 1.0-4.0, an amino acid expressed by a general formula ##STR1## (in which R represents a methyl group, an ethyl group or a methylthioethyl group) and mandelic acid, one of the acids being an optically active substance and the other being a racemic modification, and optically resolving the resulting complexes into two diastereomers by using a solubility difference therebetween. The optically active complexes are each decomposed by means of an acid, a strongly acidic ion-exchange resin, or a weakly basic ion-exchange resin to obtain optically active amino acids or optically active mandelic acid.
