Title: Prevention of color migration in electrostatic coating
Inventor: MYATA TOMOHIKO
IPC: B05D1/04
Filed: 1980-08-14
Abstract: PURPOSE: To prevent the color migration phenomenon to the preceding object to be coated by a method in which when an atomizing head is positioned between objects to be coated, an electric potential applied between the atomizing head and the object to be coated is temporarily reduced and also the rotation number of the head is raised.  
     CONSTITUTION: Objects 1 and 2 to be coated, e.g., car body, are held at positions separated by a definite distance (a) and moved at a a fixed speed in the direction of arrows. An atomizing head 3 jetting the fine particles of a paint while being turned with high speeds is positioned variably according to the height of the objects 1 and 2 to be coated. In case where the object 1 is coated with blue paint and the object 2 is coated with red paint, for example, at a stage that the coating of the object 1 is ended, a high electric potential difference which has been applied till then is reduced temporarily (for several seconds). Also, in case cleaning is made at the next stage and the next object 2 is coated, the potential difference is again reduced. When the potential difference is reduced, the number of rotation of the atomizing head is raised.

A retainer ring 16 is fitted into the operating side roll journals of upper and lower rolls 2, 5. If a jack 17, installed in the lower part of the retainer ring 16, is elevated, the drum of the upper roll 2 and the driving side upper roll chock 4 are lifted up while the spacer 14 plays as the fulcrum. Under this condition, a truck 10 is moved so as to withdraw the lower roll 5 to the operating side. When a new roll is to be inserted, the retainer ring 16 and the spacer 14 are pulled away. By the present mechanism, the rupture of the steel strip 3 is prevented, and the steel strip 13 can be laid in the mill as it is, so that the yield of production and working efficiency are improved.

Title: Method and apparatus for increasing contrast
Inventor: EEBERUHARUTO HENITSUHI
IPC: G03F3/08
Filed: 1983-06-24
Abstract: A method and apparatus for intensifying contrast during the recording of masters in electronic image processing wherein a master is scanned opto-electronically and an image signal is produced as well as two unsharp masking signals by scanning a first unsharp masking area and an enlarged second unsharp masking area around the current image point. Differential signals are generated from the image signal and each of the two unsharp masking signals and the two differential signals thus formed are mixed together in a selected ratio. The mixed signal is divided into positive and negative correction components which can be differently amplified and after comparison to threshold signals are combined to form a correction signal which has an effective width which depends on the mixing ratio. The mixing ratio may for example, be dependent on the gradient and/or the contrast of a master contour. The correction signal thus formed is then superimposed on the image signal so as to provide contrasted intensification and the contrast enhancement can be matched to the properties of the master by controlling the effective width of the correction signal.

Title: Automatic stabilization for emitted light power of semiconductor laser
Inventor: YAMABAYASHI YOSHIAKI
IPC: H01S5/0683
Filed: 1987-05-12
Abstract: PURPOSE:To automatically stabilize the emitted light power of a semiconductor laser by a method wherein photo output is monitored, the threshold value of the photo output is detected according to the magnitude of the amount of variation of the photo output to the amount of variation of a bias current and the bias current is controlled in such a way that the current is always held in the vicinity of the threshold value or right under the threshold value. CONSTITUTION:Reference photo output (Pr) and the range (DELTA) of an allowble error are given in advance and when photo output is larger than the reference photo output, a frag (Frg) is displayed as 1 and when the photo output is smaller than the reference photo output, the frag is put as -1. Then, a bias current is reduced by FrgXDELTAIb. Whether the amount DELTAP of differential variation of light at this time is suddenly changed more than a reference value (DELTAPr) is judged. If the amount does not exceed the reference value, the bias current is not changed exceeding its threshold value. Therefore, the bias current is changed until exceeding the threshold value. When the bias current is wanted to set right under the threshold value, the value of the frag is checked up at a point, when the bias current exceeds the threshold value, and in case bias is decreased, an exist from the loop takes place unconditionally. However, in case the bias is increased, this is decreased by DELTAIb to return right under the threshold value.

The medium 4 is lit up with these 1st elimination control means and the exposure feed end signal, and the 2nd discharge control means turns off the medium 4 with the return to the position of the exposure feed start. In such way, a signal source exclusive for the luminous body 4 can be excluded to simplify the constitution of a switch on and off circuit.
