Title: Method for controlling heating furnace for pipe making
Inventor: YAMAMOTO KENICHI
IPC: C21D11/00
Filed: 1987-02-13
Abstract: PURPOSE:To improve the thermal efficiency of a heating furnace for pipe making by controlling the dampers of recuperators in such a manner that the exhaust gas remaining after the amt. required for the respective recuperators is removed from the exhaust as generated in the heating zone of the heating furnace is maximized in the central part of the preheating zone for a steel strip for pipes. CONSTITUTION:The steel strip 8 as a material for pipe making is moved back and forth in the preheating zone (b) using the high-temp. exhaust gas from the heating zone (a) and is thereby preheated. The steel strip is then passed through the 1st zone Z1-3rd zone Z3 having many burners 9 so that both edges of the steel strip are heated. After the steel strip is formed to the steel pipe by a pipe is annealed in the 4th zone Z4 to relieve the stresses in the joint part; thereafter, the pipe is taken out. The temps. and flow rates of the exhaust gases in the recuperators 11-14 of the respective heating zones are measured by corresponding thermometers 2 and flow meters 3. The exhaust gas remaining after the main. amt. of the gas required for the respective recuperators 11-14 is removed is controlled by comparing the opening degrees of the dampers 61-64 of the respective recuperators with a zone reference value 7 by a control valve 4 to average the temp. in the preheating zone, by which the erosion of the furnace body by the abnormal elevation of the temp. is prevented and the thermal efficiency of the furnace is improved.

Title: Adaptive equalizing system for gmsk synchronizing detection
Inventor: SANPEI MASAICHI
IPC: H04L27/00
Filed: 1987-02-17
Abstract: PURPOSE:To reduce the effect of jitter of a recovered timing signal by utilizing the in-phase and orthogonal signal of an error when a signal crosses a zero point. CONSTITUTION:An error signal converting section 4 uses timing information of a timing recovery section to decide a sample point of an in-phase or orthogonal signal, and decides whether or not an orthogonal signal in case of the in- phase signal sampling and an in-phase signal in case of the orthogonal signal sampling crosses a zero point from the sampling point to preceding and succeeding T(sec) (T is one bit length) depending on a tap data from a transversal filter section and converts an error signal based on the information. That is, since the orthogonal signal when it crosses the zero point at the in-phase signal sampling or the in-phase signal when the orthogonal signal crosses the zero point at the orthogonal signal sampling, has less nonlinear distortion caused in the process of modulation, the estimated error of the in-phase and orthogonal signal is utilized in the case of zero crossing only so as to separate the distortion due to band limit before FM modulation at transmission from the distortion due to a reception filter.

Title: Air flow meter
Inventor: BAN TAKAHISA
IPC: G01F1/68
Filed: 1991-02-27
Abstract: PURPOSE:To prevent an error in a measured flow rate due to disturbance and drift of a flow-in air stream. CONSTITUTION:An upstream flow path constriction B and a downstream flow path constriction C larger in a flow path area than the upstream flow path constriction B are formed between a housing 1 and a center member 4. A bypass path 7 is formed inside the center member 4, while the bypass path 7 is connected to an outlet 17 which opens at the downstream flow path constriction C. Further resistors 12, 13 as hot wire type flow meters are provided in the bypass path 7. Difference in pressures according to a flow rate in a main path 2 occurs in the upstream flow path constriction C, and an air stream is led into the bypass path 7 according to the difference in pressures. Since the air stream at the downstream flow path constriction C is corrected in disturbance and drift by the upstream flow path constriction B, there is no drift in the difference in pressures occurring on the downstream flow path constriction C. Therefore an air amount which correctly corresponds to an entire air flow rate can be led into the bypass path, so that an error in measured flow rates by the resistors 12, 13 can be prevented.

Filed: 1983-03-01
Abstract: PURPOSE:To enhance accuracy, probability, and reliability, by using tracks formed on the main body of an encoder, four slits formed on detecting grids, and photodiodes having four light receiving surfaces. CONSTITUTION:A light beam 13 is uniformly projected on the entire surfaces of slit groups 8, 9, 10, and 11, and bright and dark slit images are formed in the close vicinity of each slit group. Tracks 3 and 4 of a main body 1 of an encoder are made to run on the slit-image forming surfaces. The slit groups 8, 9, 10, and 11 and the first and second tracks 3 and 4 are not physically contacted. Photoelectric conversion of the four luminous fluxes, which have passed the tracks 3 and 4, is performed by photodiodes 14, which are divided into four parts and have four light receiving surfaces D1, D2, D3, and D4 so as to face the four slit groups 8, 9, 10, and 11, respectively. By the differential amplifications of the light receiving surfaces D1 and D2 and the light receiving surfaces D3 and D4 corresponding to each track, e1 and e2 are obtained. When the rotation of a material to be measured is synchronized with the rotation of the main body 1 of the encoder, the movement of the tracks 3 and 4 can be detected by the outputs e1 and e2.
