IPC: C08F20/10
Filed: 2000-06-26
Abstract: PROBLEM TO BE SOLVED: To provide a method of producing polymerizable (meth)acrylate in which the bubbles formed by stirring are inhibited from staying on the liquid surface of the monomer. SOLUTION: The rotary shaft 3 that is vertically set in the center of the agitation tank, the first stirrer 4 that is arranged on the lowermost side of the rotary shaft 3 and has 2-6 blades (for example, 3 swept-back blades), the second stirrer 5 that is arranged over the first stirrer and has 2-8 blades (for example, 2 paddle blades), the third stirrer 6 that is arranged over the second stirrer and has 2-8 blades (for example, 2 inclined paddle blades) are integrated and they are lined with glass on their surfaces. The glass-lined stirring unit is inserted into the integrated type reactor and an alcohol and (meth)acrylic acid are subjected to the dehydrative esterification in the reactor. The bubbles staying on the liquid surface are broken since the liquid surface of the reaction mixture is renewed, as the reaction mixture is circulated by the stirrers.

Title: Method of manufacturing optical fiber
Inventor: KUCK VALERIE JEANNE
IPC: G02B6/44
Filed: 2000-06-29
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of an optical fiber, by which a desired delamination resistance can be obtained. SOLUTION: The delamination resistance of a coated optical fiber is desirably measured at two different temperatures. In particular, one is an ambient temperature in which the fiber is advantageously used, e.g. room temperature, and the other is a temperature that gives damage to the fiber used outdoors (block B). The delamination resistance in the ambient temperature is compared with the value of a preset target delamination resistance (block C). The delamination resistance in a high temperature is compared with the value that easily gives damage at a preset low target value. A coasted optical fiber having a delamination resistance outside the range of preset target values is rejected as a product but is used for application requiring a different delamination resistance (block D).

Title: Monitor camera system
Inventor: TANAKA HIDEKAZU
IPC: H04N19/503
Filed: 2000-07-13
Abstract: PROBLEM TO BE SOLVED: To provide a camera monitor system capable of performing camera monitor for a long time in a simple configuration. SOLUTION: A picture photographed by an image pickup device 101 is converted into a digital signal by a digital signal processor 102, and MPEG compressed by a picture compression processor 104, and added with data by a data adding device 105, and stored in a storage device 106. An image pickup information storing device 103 obtains photographing status data such as the diaphragm and zoom of the image pickup device, and transmits the data to the data adding device. When it is detected that the diaphragm value is more than a specific value from the data, it is recognized that a dark place is photographed, and the compression rate of the picture compression processor is increased.  Also, when the color difference data quantity of the video signal from the image pickup device is less than a specific value, the digital signal processor transmits the color difference data value as 0 to the picture compression processor so that the compression only of luminance data can be performed. Also, the compression rate is changed according to the changing situations of the image pickup information. Thus, it is possible to realize integral efficiency by performing the efficient use of the storage device or the control of a transfer interval to the outside part.
