Title: Reading and discriminating method for bar code
Inventor: UEYAMA MASATO
IPC: G06K7/10
Filed: 1986-10-31
Abstract: PURPOSE:To improve read and decision accuracy in the presence of a bar code by judging that an input image is not a bar code when the length of a window reduced so that only the input image is put therein is smaller than set minimum length in the extension direction of a single bar code. CONSTITUTION:A comparator 9 compares the window width (length in the extension direction of the single bar code) as the window length of a new window with the set minimum width to judge whether or not the new window width is larger than the set minimum width, thereby outputting data on it. The output data of the comparator 9 is inputted to a central arithmetic processor (CPU)10. The CPU10 judges that there is no bar code when the new window width is smaller than the set minimum width and outputs a signal indicating that the number of bar codes is 0. Further, when the new window width is larger than the set minimum width, it is judged that there is a bar code and a signal expressing its contents is outputted.

Abstract: PROBLEM TO BE SOLVED: To reduce a leakage current flowing through a ground caused by switching a switching element in high frequency by installing a bypass filter consisting of a capacitor connected between an AC line and the ground and a capacitor connected between a DC line and the ground. SOLUTION: A capacitor 10 is added between an LC filter circuit on the AC side and a frame 8 and a capacitor 11 between the negative pole side of a filter circuit and the frame 8. The output voltage of an inverter contains high frequency, but the high-frequency component of the output voltage is removed by the LC filter circuit on the AC side, and output voltage between AC lines is formed in a sine wave in low frequency. Voltage containing the high-frequency component can be generated between an AC line and a ground and between the ground and a DC line, but the multiple wave component of the frequency of a triangular wave is absorbed by the reactors 6a-6c of the LC filter circuit on the AC side and the filter circuit 10 and the capacitor 11, and only the low frequency of a fundamental-wave component is left.

Filed: 1998-09-11
Abstract: PROBLEM TO BE SOLVED: To provide an ultrasonic wave distance measurement device in a transmission and reception separation type reflection system that is reliable, can extend a measurement distance, and can improve measurement accuracy with a simple circuit configuration. SOLUTION: A CPU body 162 in an ultrasonic transmitter starts clocking with a frequency-dividing pulse from a frequency-dividing circuit 166 as soon as an ultrasonic sensor for transmission starts oscillating. Ultrasonic waves being discharged from the ultrasonic sensor are reflected from a distance measurement target object and are detected by an ultrasonic sensor 13 for reception. A range-finding sensitivity correction circuit 114 corrects the sensitivity of a signal from the ultrasonic sensor 13 based on sensitivity correction data. A detection circuit 130 is composed by A/DC and performs the envelope curve detection of a signal whose sensitivity is corrected. The CPU body 162 processes a detection signal and detects the detection of an accurate reflection wave, and stops the above clocking.  The CPU body 162 further calculates the distance between the measurement target object and the ultrasonic sensor based on the measured time.

Abstract: PURPOSE:To sufficiently observe even a large-bore single crystal by forming a concave surface on the tip of a quartz rod in the titled device provided with the quartz rod for observing the growth condition of the inside single crystal from the outside. CONSTITUTION:The growth condition of a single crystal in the device is observed by the quartz rod 4 from the outside in the device 6 for growing the single crystal of a easy-to-decompose compd. semiconductor consisting of an element having a high vapor pressure. In this case, one tip part (side surface part) 7 of a rod 4 is made concave to the outside, and the radius of curvature is made smaller than the distance between the tip part 7 and a body 8 to be observed. Since the tip part 7 is made concave in this way, the same action as a lens is provided, and the visual field is widened with the same diameter. When the angle between the normal 3 at the worked tip part and a light beam 2 passing through the quartz rod is assumed to be theta1 and the angle between the normal 3 and a light beam 1 passing through a gas to be theta2, the equation can be obtained by the Snell laws of refraction (n1 and n2 are the refractive indexes of the respective mediums). Since n1>n2 in this case, theta1<theta2, and the visual field is widened.

IPC: B01J31/00
Filed: 1987-10-16
Abstract: The present invention provides a method for varying the melting points and molecular weights of polyolefins by changing the structure of the catalyst used in the polymerization. The catalysts that are useful in the present invention are chiral, stereorigid metallocene catalyst of the formula R''(C5R'm)2MeQ. The catalysts include a bridge structure between the (C5R'm) groups and may contain substituents on the groups. It has been discovered that the melting points and molecular weights of the polymers produced by such catalysts are influenced by the bridge and substituents added to the (C5R'm) groups. Thus, the present invention provides a method for varying the melting points of the polymer product and a method of varying the molecular weights of the product by changing the components and structure of the metallocene catalysts. The present invention also provides a process for polymerizing olefins in which the melting points and/or molecular weights of the product may be controlled. Also included in the invention is the discovery that the melting points of the products are controlled by the number of inversions in the xylene insoluble fraction of the polymer.
