Title: Rolling method by work roll shift rolling mill
Inventor: OCHIAI TSUNEO
IPC: B21B1/24
Filed: 1987-01-24
Abstract: PURPOSE:To disperse roll wear and thermal crowns and to improve a sheet crown and edge drop by applying a sheet crown method or edge drop method to the front stage of a rolling mill train and a cycle shift method to the rear stage. CONSTITUTION:The sheet crown method or edge drop method is applied to the front stage, for example, F1-F3 where the roll wear is small, of the rolling mill train having >=2 units of work roll shift devices. Rolling is executed by controlling the roll shift positions regardless of the width of the materials by every one or plural pieces of the materials in the rear stage, for example, F4-F7, where the roll wear is large. The roll wear and thermal crowns are thereby dispersed and the sheet crown or edge drop is improved.

Inventor: OKADA ATSUSHI
IPC: F28F1/32
Filed: 1994-01-13
Abstract: PURPOSE:To obtain uniform heat-exchanging capability over the entire face of an heat exchanger by a method wherein the arrangement pitch of multiple tubes-penetrating through multiple plate fins arrayed in parallel and extending along a direction orthogonal to the fins, is set narrower in a region where an air flow rate is large and wider in a region where an air flow rate is small. CONSTITUTION:A plate fin and tube type heat exchanger 3 in a wall type air conditioner comprises multiple plate fins 32, which are spaced at very short intervals in a horizontal direction, mutually arrayed in parallel and extend in a substantially perpendicular direction, and multiple tubes 31, which penetrate through the fins 32 and extend in a horizontal direction along a direction orthogonal to the fins 32. In this case, the arrangement pitch of the tubes 31 is set narrower PA in a region where an air flow rate is large, that is, at a central part 3A, and wider PB in regions where an air flow rate is small, that is, at upper and lower end parts 3B according to an air flow rate distribution on the front face of the heat exchanger. By this arrangement, a heat transfer rate is made substantially equal in the vertical direction of the heat exchanger 3, and the heat transfer rate of the heat exchanger 3 as a whole is increased.

IPC: H04N5/18
Filed: 1991-02-06
Abstract: PURPOSE:To generate a dither signal immune to dither accurately without effect of a wire by varying a clamp level so as to implement dither. CONSTITUTION:A variable clamp level generating circuit 13 varies a clamp level applied to a clamp capacitor C, in response to error information and vibrates the clamp level for a prescribed period longer than a clock period of an A/D converter 11 for each prescribed period. A video signal inputted to a terminal 10 is clamped to a clamp level from the variable clamp level generating circuit 13 by the capacitor CC and the result is inputted to the A/D converter 11, in which the signal is converted into a digital data, The clamp level generated by the variable clamp level generating circuit 13 is vibrated for a prescribed period and since the amplitude is equivalent to, e.g. a pulse train of 1/2 LSB, dither operation is given to the input signal. Thus, circuit integration is attained and an accurate dither signal immune to noise is generated.

Abstract: PROBLEM TO BE SOLVED: To provide a film scanner for shifting pixels without constituting a drive mechanism of any special members. SOLUTION: This film scanner is provided with a guide moving device 5 for moving a negative film 6 in the direction vertical to an optical axis connecting a light source 1 with a photometry device 3.
