Title: Method for detecting and adjusting pressing pressure of conducting roll
Inventor: NISHIMURA KAZUNARI
IPC: G01L5/00
Filed: 1983-04-01
Abstract: PURPOSE:To stabilize the pressing force of a conducting roll and to improve plating quality by grounding the circuit between the brush of a conducting roll in rolling contact with a continuously fed strip in a plating device and the negative electrode of a plating power source and detecting the grounding current thereof. CONSTITUTION:Plating current is conducted between anodes 5, 5 opposed to a continuously fed strip 1 and a conducting roll 2 for cathode in rolling contact with the strip 1 from an electric power source 8 via a plating soln., so that the strip is plated. A brush 6 for conducting the roll 2 to the negative electrode of the power source 8 and said negative electrode are grounded through an ammeter 7. Since the strip 1 is grounded in the adequate place of the conveyance system for the same for the sake of safety, the plating current flows through the strip 1, the contact point thereof and the ammeter 7 to the negative electrode of the power source 8 separately from the above- mentioned circuit. Such grounding current can be thus detected with the ammeter 7 and the indirect detection of the pressing force of the roll 2 on the strip 1 is made possible in accordance with the detected value. The pressing force of the roll 2 is thereupon so adjusted as to maintain the specified value to be detected with the ammeter 7.

Title: Molecular method for producing hybrid seed
Inventor: FABIJANSKI STEVEN F
IPC: C12N15/09
Filed: 1996-02-08
Abstract: A process is described for producing fertile hybrid seed or hybrid seed comprising fertile and sterile seed using male-sterile plants created by employing molecular techniques to manipulate anti-sense gene and other genes that are capable of controlling the production of fertile pollen in plants. Transformation techniques are used to introduce constructs containing anti-sense DNA and other genes into plants. Said plants are functionally male-sterile and are useful for the production of hybrid seed by the crossing of said male-sterile plants with pollen from male-fertile plants. Hybrid seed production is simplified and improved by this invention and can be extended to plant crop species for which commercially acceptable hybrid seed production methods are not currently available.
