Title: Bar code reader
Inventor: NAKAMURA TATSUYA
IPC: G06K7/10
Filed: 1988-06-24
Abstract: PURPOSE:To eliminate an external light component and to improve an S/N by blinking a light emitting element and sampling the output signals of a light receiving element obtained in its ON and OFF states via 1st and 2nd sample and hold circuits respectively to calculate the difference between both sampled signals through a subtraction circuit. CONSTITUTION:The clock signal CK outputted from a pulse oscillation circuit 2 drives a light emitting driver 4 and blinks a light emitting element 10 synchronously with the signal CK for irradiation of a bar code medium. The reflected light received from the bar code medium is inputted to a light receiving element 12 and converted into the electric signal. Then the output signals of the element 12 obtained in its ON and OFF states are sampled by the 1st and 2nd sample and hold circuits 6 and 8 respectively. The difference between both sampled signals is calculated by a differential amplifier circuit 16 for elimination of the influence of the external light. Thus the S/N is improved.

Title: Automatic arranging and wiring systems
Inventor: SAKAGUCHI KAZUYUKI
IPC: H01L23/52
Filed: 1990-06-12
Abstract: PURPOSE:To semiautomatize the manual rewiring required at modification of cell arrangement by providing a function part, which abstracts the routes of wiring and the positions of cell arrangement, and wiring it based on this abstracted manual wiring information. CONSTITUTION:Rules and physical information and connecting information on circuits required for automatic wiring are input from the input part 1 into data base 6, and the arrangement of cells is performed, using an editor function part 2. At this time, the information on the positions of cell arrangement is abstracted, and it is secured in the manual wiring information part 10 in the data base 6. Next, the left wiring is automatically wired by an automatic wiring function part 4. When the wiring is completed, using a compacting function part 5, chip areas are reduced one by one. Hereupon, when the modification of cell arrangement becomes necessary, using the editor function part 2, all wirings are deleted, and then the arrangement of cells is modified semiautomatically. With this, the manual rewiring work can be relaxed, and the layout design period of an LSI/IO chip can be shortened.

Title: Appreciation device for hidden image
Inventor: HANABUSA KENJI
IPC: A63H33/22
Filed: 1990-06-13
Abstract: PURPOSE:To provide a means for correcting an image difficult to appreciate or read to an image easy to appreciate by providing a reflecting surface provided with fine recessed grooves parallel to a mirror surface optically called a reflecting type concave diffraction grating. CONSTITUTION:A reflecting mirror 2 is inclined at an angle of about 45 deg.C with respect to an image source P and the image reflected from the surface 2a of the reflecting mirror 2 is observed. Since the light incident to an eye E reaches the eye as straight advance light L and distorted light D, the left and right opposite images due to the straight advance light and a distorted image (or a diffracted image) are simultaneously looked with respect to the whole of the image. In such a system that a concave-convex reflecting mirror and a flat mirror are obliquely crossed each other at an obtuse angle, the light incident to the eye E from the image source D is reflected twice by the concave- convex reflecting mirror 2 and the flat mirror 3 to be formed into a positive image and, since the straight advance light L' from the image source is simultaneously observed, the sharpness of the image is high but the shaking of an eye axis is required in the recognition of the image.

Title: Sheet counting device
Inventor: ICHIKAWA KIYOSHI
IPC: G06M7/06
Filed: 1979-11-29
Abstract: PURPOSE: To transport the sheets in separation from each other, by forming the friction surface to transport the sheets and the smooth surface to transport no sheet each on the outer circumference surface of the lead-in roller.  
     CONSTITUTION: The sheets which are sent successively into the lead-in roller from the sheet holding part 2 are held between the friction surface 10b of the roller 10 and the holding guide 11 and then drawn in by the friction to be counted by the detecting means 29. In this case, the 2nd sheet 7 is sent into the roller 10 subsequently the 1st sheet, and the tip of the sheet 7 touches the smooth surface 10c of the roller 10. Accordingly, the sheet 7 is never drawn in and then drawn in when the roller 10 turns to secure a contact between the surface 10b and the tip of the 2nd sheet. Thus the sheet 7 is drawn in intermittently to be counted. When a fixed number of sheets is counted in such way, the rotation of the roller 10 is stopped immediately before the sheet 7 is drawn in. As a result, the next sheet 7 is never drawn into the roller 10, and accordingly no sheet 7 remains within the counting device.

Title: Power interruption alarm
Inventor: TANIGUCHI EI
IPC: H02H3/247
Filed: 1993-06-25
Abstract: PURPOSE:To provide a power interruption alarm in which the detection level and the detection time can be set arbitrarily through a simple circuitry requiring only one level detector. CONSTITUTION:A voltage comparator 3 compares a rectified voltage from a rectifier 1 with a detection voltage determined by means of a volume R1 at a detection voltage setter 2. The voltage comparator 3 delivers an output signal only when the rectified voltage is higher than the detection voltage. When the commercial power supply for the rectifier 1 is normal, a timer 5 is turned ON/OFF by a regular signal but when the commercial power supply voltage drops, a control signal is delivered from the timer 5 to an AND circuit 9 with a time lag determined by a volume R2 interlocked with the volume R1. A timer 7 having a detection time being set by a detection time setter 8 similarly delivers a control signal to the AND circuit 9 upon voltage drop thus actuating an alarm 6 in conjunction with the aforementioned control signal.

Abstract: PURPOSE:To supply only the necessary amt. of compressed air stably and economically in the air oxidation of slurry discharged from an absorption tower by detecting the amt. of supplied compressed air and the amt. of discharged air and controlling the amt. of compressed air to be supplied to an oxidation tower basing on the difference between both detected amt. of air. CONSTITUTION:Slurry discharged from an absorption tower consisting essentially of CaSO3 and gypsum is led to an oxidation tower 1. The amt. of compressed air 3 supplied to the oxidation tower 1 and the amt. of discharged air 4 to the outside of the system after oxidation of CaSO3 in the oxidation tower 1 are detected with detectors 5, 20 respectively, and the difference of the detected values is calculated by a subtractor 21, and the signal obtd. by the calculation is converted by an amplifier 22 to a setting signal 24 for the amt. of supplied compressed air and inputted to a flow controlling 6. If the amt. of SO2 to be desulphurized in the absorption tower increases, the amt. of CaSO3 to be oxidized in the oxidation tower 1 increases also gradually, and the amt. of air to be discharged decreases. Therefore, the value of flow amt. instructed by the flow amt. set signal 24 increases, and the amt. of supplied compressed air is increased by the flow amt. controller 6.
