Title: Line-of-sight detecting device
Inventor: KODAMA SHINICHI
IPC: A61B3/113
Filed: 1993-04-27
Abstract: PURPOSE:To eliminate an erroneous line of sight signal and to realize operation according to the more accurate line of sight signal by judging the blink of a photographer which is a noise signal at high speed by simple constitution in the case of performing the operation of a camera by using the line of-sight signal. CONSTITUTION:When a light projection part 1 projects light toward the eyeball 90 of the photographer, a light receiving part 2 detects reflected light from the eyeball 90 of the photographer, and a control part 3 controls the projection of light by the light projection part 1 and the detection timing of the light receiving part 2. A light quantity decision part 4 detects the blink of the photographer by deciding light quantity in the same area as the light receiving part 2, and a line of sight detection part 5 detects the line of sight based on a signal from the light receiving part 2. Furthermore, the detection part 5 detects the line of sight based on a value from the decision part 4. In the case the decision part 4 detects the blink of the photographer, the detected result on the line of sight by the detection part 5 is invalidated.

IPC: B41J29/26
Filed: 1991-05-08
Abstract: PURPOSE:To print a horizontally ruled line on the center of a printing line of an arbitrary height. CONSTITUTION:In a line memory 1, a height (p) of a printing line and a predetermined character code are prestored. An address generator 2 outputs a base address (x) of a ruled line pattern matrix stored in a pattern memory 9. A character code discriminating circuit 6 for discriminating a character code from the line memory 1 outputs (q). A divider 4, a divider 5, and an adder 7 respectively output p/2, q/2, and p/2+q/2. A subtracter 11 outputs {p-(p/2+q/2)} obtained by subtracting the output of the adder 7 from the output of a register 3. A selector 13 outputting either the output of the subtracter 11 or the output of a counter 12 on the basis of the output of the character code discriminating circuit 6 outputs the output of the subtracter 11 when a character code is a ruled line pattern matrix. A dot transmittion circuit 10 reads dot string data of the ruled line pattern matrix from a pattern memory 9 on the basis of the outputs of the address generator 2 and the selector 13 and issues it to a printer part 14. As a result, a horizontally ruled line part of the ruled line pattern matrix is printed on the center of a predetermined line.

IPC: A01N25/20
Filed: 1982-06-14
Abstract: PURPOSE:To suppress the extraction of components from a base in a small- amount and extract only active constituents quantitatively and rapidly with ease, by carrying out the recovery of the active constituents from a mosquito-repellent incense with a mixed solvent containing formic acid by the shaking method. CONSTITUTION:A mosquito-repellent incense is finely pulverized to 100 mesh or less paticle size, and then extracted with a mixed solvent containing formic acid to recover quantitatively active constituents, e.g. allethrin, natural pyrethrin or terallethrin. A solvent used together with the formic acid is preferably immiscible with the formic acid, and has a smaller specific gravity than the formic acid, and toluene is suitable. For example, the formic acid and toluene is used in 1:5 volume ratio. The method provides an extremely shorter extraction time and smaller amount of tarry or high-viscosity components extracted from the base in the incense by easier operation and a higher extraction ratio than those in the conventional Soxhlet extraction method.
