Title: Preventing system for erroneous read
Inventor: HOSHINO EIICHI
IPC: G06K7/10
Filed: 1981-06-23
Abstract: PURPOSE:To reject the read when a label code for another goods is stuck, by detecting a bar-code signal inputted within a certain time and demodulating this signal and holding it after discriminating left and right parts and comparing all characters in left and right blocks with each other. CONSTITUTION:The read signal of a bar-code is transmitted to a counting circuit 1, and ''1'' and ''0'' are outputted for black bars and white bars respectively. A start signal is generated by a start signal detecting circuit 2 and is controlled in a controlling part 6, and the character demodulation is performed in a character demodulating circuit 3 in accordance with lengths of ''1'' and ''0'', and a center code is detected by an end signal detecting circuit 4. These outputs are processed in a left and right discriminating circuit 7 and are stored in a holding circuit 8. If a label for another goods is stuck and bar-code data of two labels are demodulated and held in the circuit 8, characters in left and right blocks are compared with each other in first and second comparing circuits 9 and 10. If a information is not coincident as the result, the read is rejected as an erroneous read.

IPC: B29D30/44
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To manufacture without using solvent by at least partly treating a surface of specific unvulcanized rubber mixture by plasma and/or flame, thereby increasing assembling adhesive properties of the mixture. SOLUTION: A surface of at least one unvulcanized rubber mixture is at least partly treated by plasma and/or flame. For example, an electrode head having two electrodes 1 is approached to the mixture 3, and gas particles 2 discharged while the electrodes 1 are ignited is operated on the surface 4.

Title: Acoustic type edge sensor
Inventor: ISHII YASUSHI
IPC: G01V1/00
Filed: 1985-05-10
Abstract: PURPOSE:To provide an endurance against contamination, by utilizing a sharp change in acoustic impedance as caused at one end of a sound tube as the edge of an object to be measured under the tube end with the traversal movement thereof when the end of the sound tube is placed facing the object. CONSTITUTION:The frequency of an oscillator 6 is fixed at omega=omega2n+1 (wherein omega is angular frequency and n=0, 1, 2...) and the object 3 being measured moved to the right. First, the sound pressure in the sound tube 1 is large in the amplitude with the sound tube 1 resonating having one end thereof open but it reduces sharply with the tube 1 shifting to the state of both ends closed as the edge 3 thereof 3 is passing under a flange 2. In other words, the relation between the coordinate value x of the edge 4 and the output E is as shown the solid line in the drawing B and hence, the position of the edge 4 can be detected by the size of the output E. Then, the frequency of the oscillator 6 is fixed at omega=omega2n. If so, since this is resonance frequency with both ends the tube closed, the sound pressure in the tube will increase as te end of the tube is closed with the passage of the edge 4 through the flange 2. As a result, the characteristic becomes as shown by the dotted line in the drawing B and also in this case, the position of the edge 4 can be detected from the size of the output E.
