Title: On-line shape measuring method
Inventor: MATSUBARA TSUTOMU
IPC: G01B21/20
Filed: 1988-08-15
Abstract: PURPOSE:To improve the accuracy of shape measurement and to improve the operation efficiency by rolling and moving a moving roll group while pressing it against a steel plate and thus put the roll group close to a roll group at a fixed position, and measuring the angles of rotation of respective rolls in the roll group at the fixed position. CONSTITUTION:The steel plate is released from tension into a notension state and stopped on a surface plate installed on a line. Two roll groups, i.e. the moving roll group 1 and fixed-position roll group 2 of rolls which are equal in diameter in the width direction of the steel plate are arranged on the steel plate 3 in parallel at a constant distance L on the in and out sides on the surface plate and brought into contact with each other. The moving roll group 1 is rolled and moved toward the fixed-position roll group 2 and made to contact it. At this time, no slip is made between the moving rolls 1 and steel plate 3. The rolls in the fixed-position roll group 2 are provided with a rotation indicator and the angle of rotation of each fixed-position roll is measured from the line length difference in a measuring direction to calculate the steepness of local elongation from a specific formula by using the angles of rotation.

Filed: 1983-10-28
Abstract: PURPOSE:To attain speed-up and power saving of preheating as well as lengthen the life of thermal head by utilizing the heat of resistors for driving a stepping motor to raise the internal temperature for preheating of a thermal head. CONSTITUTION:When the temperature of open air is low, the output of a temperature detector 7 is compared with reference voltage source 8 by a comparator 9.

A stepping motor 1 is driven and at the same time the thermal head is quickly heated by the heat of the resistor 4. When the head reaches a printable temperature, the output of the comparator 9 is changed to switch the circuit 5, and drive current is supplied to the motor 1 through the resistor pair 3 of A earthed in a place where ventilation of air is good. In this case, the heat produced in the resistor pair 3 is released to outside and the effect of heat on the thermal head can be avoided.

Filed: 1989-08-05
Abstract: PURPOSE:To detect the package state of the electronic component with high accuracy by comparing the areas and shapes of 1st and 2nd pieces of image information with each other and inspecting the position shift of the electronic component. CONSTITUTION:A red mark is formed in an area of a printed board 1 where the electronic component is mounted with red paint. This board 1 is irradiated with light and an inspection window which has an area similar to that of the area where the red mark is formed is set by a computer 7; and reflected light reflected by the read mark is picked up in the inspection window by a television camera 5 with a filter 23 transmitting light with red wavelength and its image information is stored in the computer 7. Then electrodes are soldered and mounted and the mounting area is put in the inspection window; when the electronic component is mounted in an expected mounting area, a black image is obtained. If the electronic component shifts in position from the expected area, a white image having a specific area is formed in the inspection window. Thus, the computer 7 calculates the number of picture elements constituting the area of the white image to decide the position shift of the electronic component.
