Abstract:
A visual presenter includes a base, an upright portion standing from the base and having a distal end, a support column including a horizontal portion formed by bending the distal end of the upright portion so that the horizontal portion protrudes forward away from the base, the horizontal portion having a distal end, an imaging camera head mounted on the distal end of the horizontal portion, and a pivot portion provided on the upright portion of the support column so that the horizontal portion is pivotable horizontally.
Abstract:
A visual presenter includes a base, a column support including an upright part and a horizontal part, and a camera head mounted on a distal end of the horizontal part. The horizontal part includes first and second horizontal parts. The first horizontal part is mounted on a first support shaft further mounted on the upright part, so as to be pivotable between a downwardly extending position and a horizontal position. The second horizontal part is mounted on a second support shaft further mounted on an end of the first horizontal part located opposite the first support shaft side, so as to be pivotable between a horizontal backward position and a horizontal forward position.
Abstract:
A visual presenter includes a camera support arm pivotally mounted on a base and having one end on which a camera is mounted, a pivot support including a bracket, a pivot having one end formed with a male thread, a disc spring fitted with the male thread and a nut brought into threading engagement with the male thread so that the spring is fastened to the bracket by the nut with a result that a brake force is effected and a free stop function is given to the pivot support, and a one-way clutch fitted with the pivot to allow the pivot support to be free against rotation causing the pivot support to stand up and to exert a clutching function against rotation causing the pivot support to lie. The camera support arm is pivotally mounted on the pivot support with the one-way clutch being interposed between them.
Abstract:
A code processing circuit includes a plurality of coders which encode different kinds of data, respectively, a first buffer which stores the codes outputted from the coders provided corresponding to the plurality of coders, a second buffer which stores the lengths of the codes outputted from the coders provided corresponding to the plurality of coders, a first adder which adds the code lengths stored in the second buffer provided corresponding to the plurality of coders, a second adder which adds all the code lengths added in the first adder, and an adjustment unit which adjusts an output code by the unit of 1 bit based on the codes stored in the first buffer, the code lengths stored in the second buffer and the code lengths added in the second adder.
Abstract:
An aromatic polyesterpolycarbonate containing a dihydroxy-diaryl compound residue, a terephthalic acid residue and/or isophthalic acid residue, and a carbonate bond in a molar ratio of 1:0.25-0.75:0.75-0.25 is prepared by first mixing and reacting an aqueous alkaline solution of a dihydroxy-diaryl compound, an organic solvent solution of terephthaloyl chloride and/or isophthaloyl chloride, and phosgene to obtain a polyesterpolycarbonate oligomer having --OCOCl groups, --COCl groups and --OH groups as end groups and then subjecting the oligomer to polycondensation with a caustic alkali in the substantial absence of the dihydroxy-diaryl compound.
Abstract:
The frame holding time can be materially extended without increasing the counter size by insertion of a delay circuit and an AND gate between the framing detector and hunting means. Hunting operation is performed under control of the logical AND of the detector output and its retarded counterpart. The frame holding time obtained in the present invention corresponds to the sum of the retardation time of the delay circuit and the frame holding time of the conventional device.
Abstract:
A head arm pivot shaft support mechanism 180 has a cord covering unit 200 including a first part 210, a second part 220, and a third part 230. The first part 210 and the second part 220 are located on a side of one head-side engagement leg 186 of bifurcated head-side engagement legs 186 and 187 and are arranged to be rotatable about a pivot shaft member 193. The first part 210 and the second part 220 respectively have an arc-shaped peripheral wall 212 and an arc-shaped peripheral wall 222 protruded toward the third part 230 to fill a space on a bifurcation base side between the bifurcated head-side engagement legs 186 and 187. The third part 230 is located on a side of the other head-side engagement leg 187 and is arranged to be rotatable about the pivot shaft member 193. The third part 230 has a first arc-shaped peripheral wall 233 and a second arc-shaped peripheral wall 234 protruded toward the first part 210 and the second part 220 to fill spaces between edges of the arc-shaped peripheral wall 212 of the first part 210 and edges of the arc-shaped peripheral wall 222 of the second part 220. A cord extended from an internal camera incorporated in a camera head 150 runs through a cut 215 formed in the arc-shaped peripheral wall 212 and a cut 225 formed in the arc-shaped peripheral wall 222 and is covered with these arc-shaped peripheral walls 212 and 222 with avoiding interference with the pivot shaft member 193.

Abstract:
To achieve both uniform illumination and a reduction in the LED light sources, after simplifying illumination control of the light sources. In an illumination unit 130, when arranging LED light sources in a linear arrangement on a light source base plate 160, installation thereof will be thinned out in the center, while providing the base plate left and right ends with LED light sources 160L1 and L2 and LED light sources 160R1 and R2. The light emitted by the LED light source 160L1 and the LED light source 160R1 will be reflected by a left inside wall face 131LS and a right inside wall face 131RS respectively, and directed onto the table upper face. The light emitted by the LED light source 160L2 and the LED light source 160R2 lying towards the center zone of the light source array where the light source placement has been thinned out will be reflected by a left outside wall face 171LS and a right outside wall face 171RS respectively, and directed onto the table upper face.
