A pattern of grooves or holes is formed in metallic electrodes disposed in upper and lower sides with respect to a vibration member in a capacitance type dynamic quantity sensor. As a result, even when an electrode made of a single electrically conductive material such as Al is used, it is possible to avoid the generation of hillocks on the surface of the electrode, and film-peeling risk of the electrode can be reduced. In addition, the manufacturing cost can also be reduced.

When applying a coating film by a spin coating method on a disc-shaped recording medium, the film thickness difference between the inner rim and the outer rim of the disc has to be suppressed. To this end, a coating liquid is supplied to a center portion of the disc-shaped recording medium and a rotary disc, as a center shaft of a rotary disc is inserted into a recess formed in a turntable on which the disc-shaped recording medium is set and the disc-shaped recording medium and a rotary disc are run in rotation. The coating liquid is spread under the centrifugal force caused by rotation for forming a coating film on the disc-shaped recording medium.

The present disclosure provides a transfer plate. The transfer plate includes a base film, and a dot array arranged on the base film and consisting of a plurality of dots. The base film includes an active region corresponding to a display region and a non-active region surrounding the active region. The dot array at the active region is of a first dot angle, and the dot array at the non-active region is of a second dot angle less than the first dot angle.

An object of the present invention is to provide a production apparatus for electro-deposited metal foil or the like that can reduce thickness fluctuation of electro-deposited metal foil. To achieve the object, a production apparatus for electro-deposited metal foil or the like in which a cathode and an insoluble anode apart from each other, supplying an electrolytic solution through a gap between the cathode and the anode, making the cathode move along to the insoluble anode, electrodepositing a metal component on an electro-deposition surface of the moving cathode is applied. Wherein the insoluble anode is a thin plate insoluble metal electrode provided with a conductive electrode material coating layer on a surface of a substrate made of a corrosion-resistant material, and detachably mounted to an electrode base by using predetermined fixing means, and the conductive electrode material coating layer of the thin plate insoluble metal electrode is provided with a conductive electrode material stripped belt in a direction perpendicular to a moving direction of the cathode, and the fixing means is provided in the conductive electrode material stripped belt.

The invention discloses a rolling control method capable of lowering the influence of watermarks of walking beams of a heating furnace on the thickness of finished products. The method is characterized by including the following steps that 1, the number of the walking beams in the heating furnace and the size of the heating furnace are detected; 2, the number of watermark points and the position of each watermark point are calculated according to the number of the walking beams and the size of the heating furnace; 3, the watermark influence coefficient of each watermark point for rolling force is calculated; and 4, actual rolling force of the watermark points is calculated according to the watermark influence coefficients. By the adoption of the technical scheme, the influence of the watermarks of the walking beams of the heating furnace on the thickness of finished moderately-thick plates can be lowered, and especially, the thickness fluctuation caused by the watermarks can still be effectively relieved under the condition of short time in the heating furnace; and the hourly output of thick plates and the thickness and accuracy of the finished products can be guaranteed, and quality losses are reduced.

The invention discloses a cold continuous mill thickness extension feed-forward control method. The cold continuous mill thickness extension feed-forward control method comprises the steps that a first thickness gauge, a second thickness gauge and a fifth thickness gauge are installed in front of an inlet of a first rack, an inlet of a second rack and an inlet of a fifth rack correspondingly, the first thickness gauge, the second thickness gauge and the fifth thickness gauge are used for measuring the thickness deviations of incoming materials at the inlet of the first rack, the inlet of the second rack and the inlet of the fifth rack correspondingly, and the thickness deviations are used for feed-forward control of the first rack, the second rack and the fifth rack correspondingly; the thickness deviation of an inlet of a third rack is estimated according to the thickness deviation actually measured by the second thickness gauge, and the estimated thickness deviation of the inlet of the third rack is transmitted to the third rack so that thickness feed-forward control can be conducted; and the thickness deviation of an inlet of a fourth rack is estimated according to the estimated thickness deviation of the inlet of the third rack, and the estimated thickness deviation of the inlet of the fourth rack is transmitted to the fourth rack so that thickness feed-forward control can be conducted. By means of the cold continuous mill thickness extension feed-forward control method, the strip steel thickness control precision is improved.
