Inventor: TANAKA KENICHI
IPC: C21D7/00
Filed: 1984-04-14
Abstract: PURPOSE:To obtain a steel pipe having extremely high collapsing strength in a method for heating the hardened and tempered steel pipe to a prescribed temp. and working the pipe by using 4 pieces a set of specific rolls in place of a strainer in specific working of said pipe. CONSTITUTION:A hardened and tempered steel pipe 1 is applied with compressive load P at 4 points on the outside circumference thereof by means of 4 pieces a set of parallel rolls 21, 22, 31, 32 in the >=3 positions apart from each other in the axial direction of the pipe under the temp. conditions of >=300 deg.C and below the tempering temp. The pipe 1 is thus acted with bending force and is subjected to the working to generate required deformation in the specific diametral direction of the pipe and to rotate at least half the pipe around the axis of the pipe while maintaining the deformation. The roll load is thereafter gradually removed under rotation of the pipe by maintaining the specified change rate of the above-described deformation with respect to said rotation and setting the rotating amt. of the pipe in the process of removing the load at >=1 rotations. Such operation is subjected to the overall length of the pipe. The yield strength, out of roundness and the residual stress distribution in the inside surface of the pipe are thus respectively improved and the collapsing strength is improved.

Title: Device and method for automatically calibrating branch flow rate in hvac distribution system
Inventor: AHMED OSMAN
IPC: F24F11/00
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To automatically start the operation of a flow rate distribution system for heating, ventilation and air conditioning(HVAC) calibrating a fluid flow rate at the branch of a system based on the fluid flow rate of each measured by the output of a source constitution output part and the input of a local control constituting part. SOLUTION: A process for calibrating the individual branch flow rate of the system is automated. This system uses the flow rate sensor 20 of a fan exit as an independent source measuring a flow rate at each terminal unit 1 to 4. Then a damper is closed at each branch of the system to measure a flow rate value at the output of a driving-motor and the input of the damper. After then the damper is opened by 50% to measure a flow rate value at the output of the driving-motor and the input of the damper again. Next, a flow rate coefficient correlating the difference of a flow rate measured by the output of the driving-motor with the difference of a flow rate measured by the input of the damper is obtained. The passing flow rate of each damper at each branch is calibrated like this manner.

Title: Electrophotographic method
Inventor: OOKUBO MASAHARU
IPC: G03G15/00
Filed: 1983-04-28
Abstract: PURPOSE:To prevent generation of a picture failure by stopping the respective operations in order of a transfer electrifier, a photosensitive electrifier, and a pre-exposing means, after a transfer is ended. CONSTITUTION:At a time T6 later than a time point T5 of the end of a transfer, an operation of a transfer 6 electrifier 12 is ended. Subsequently, at the time point when the surface part of a photosensitive body on which the electrifier 12 has operated at the time T6 has reached a photosensitive electrostatically charged part C, or at a time T7 being a later time point than said time point, an operation of an electrifier 4 stops. Accordingly, the photosensitive body part which has been subjected to an operation of the transfer electrifier 12 is all exposed by a light source 3 thereafter, also operated by the electrifier 4, and the surface potential of the photosensitive body becomes uniform. Also, at the time point when the surface part of the photosensitive body on which the electrifier 4 has operated at the time T7 has reached a pre- exposing part P, or at a time T8 being a later time point than said time point, the light source 3 is turned off. As a result, the surface part of the photosensitive body which has been subjected to an operation of the electrifier 4 is all exposed by the light source 3, and an electrostatically charged charge is annihilated or attenuated. Accordingly, the potential of the photosensitive body is attenuated to a uniform low potetial or zero potential, can be left as it is in a state that no electrostatic charged memory nor optical memory is generated, and a picture formation of the next time can be executed satisfactorily.
