Title: Identification of temperature rise pattern in heating furnace
Inventor: ARAI KAZUO
IPC: G01K3/02
Filed: 1990-04-09
Abstract: PURPOSE:To obtain a highly accurate temp. rise pattern by respectively fixing the emissivity inevitable to thermometry using a radiation thermometer and the overall heat absorptivity inevitable to the estimate calculation of a temp. rise in the heating of an atmosphere on-line. CONSTITUTION:The temp. T0 of a material on the inlet side of a preheating zone 1 and the temps. TF1-TF3 in a furnace of respective preheating, heating and soaking zones 1,2,3 are measured and the brightness temps. T1-T3 of the material are detected on the outlet sides of the respective zones by radiation thermometers. Further, the overall heat absorptivity in each of the zones is represented by phiCG=phi0+at<n> (wherein phi0 is an initial value, (t) is a stay time, (n) is degree and (a) is a differential coefficient). Further, the emissivity epsilon of the material is set to the function of phiCG and the mean surface temps. -T11-T13 of the material on the outlet sides of the respective zones are calculated using T and epsilon and the mean temps. -T21-T$23 of the material at the positions of respective radiation thermometers are calculated from Temps. T0, TF and the initial value phiCG. Then, the coefficient (a), the degree (n) and the initial value phi allowing the temps. -T11... to coincide with the temps. -T21... with necessary accuracy are found out. When (a), (n) and phi0 are determined, the temps. -T11... or -T21... at that time are determined as the mean temps of the material on the outlet sides of the respective zones and the temp. rise calculation result calculated at the same time is used to identify a total temp. rise pattern.

Title: Charging method of resin in press molding
Inventor: INOUE TORU
IPC: B29C43/02
Filed: 1988-04-14
Abstract: PURPOSE:To improve molding by extruding a resin from a nozzle under a molten state and respectively extruding the resin to a bead shape in a plurality of rows along the direction of transfer of the nozzle when the resin is charged to a bottom force. CONSTITUTION:A plurality of extruding ports are respectively opened downward at regular intervals along the cross direction in the extruding sections of a resin in a nozzle 3, and an extruded resin W is formed to a bead shape and extruded. Consequently, when the resin is extruded extending over approximately the whole surface of a mold surface, and a mold 4 is closed instantaneously and the resin is molded. Since each extruded resin W is formed to the bead shape respectively at that time, the resin W is applied in thickness thicker than coating extending over the whole surface. Since the resin is extruded in an approximately circular section, a contact area with a molding die is reduced, thus lengthening the heat holding time of the resin W. Since the temperature difference of the resin W due to the difference of the charging time is decreased, the lowering of the fluidity of the resin is inhibited, thus preventing trouble such as the generation of broken section in a molded form.

Title: Signal processing unit
Inventor: YONEYAMA MASAYUKI
IPC: H04B1/62
Filed: 1984-05-08
Abstract: PURPOSE:To use an emphasis amount more than conventional amounts by passing a signal once through a transmission circuit in a positive time series and outputting the signal through the same transmission circuit in the opposite time series next to bring the phase characteristic of the transmission circuit to zero phase. CONSTITUTION:The period of an input signal to be processed in this unit covers an (nH+alpha+beta) period from a time alpha to a time beta before nH period and the input signal passes twice through the 1st, 2nd and 3rd transmission circuits 6, 7, 8. The time series is the positive time series when the 1st input signal passes and a negative time series at the 2nd passing. When the signal of the same time series as the time series of the input signal is desired to be obtained, a time series inverting circuit has only to be connected to the output terminal of the system in the figure. It is difficult to realize a complete zero phase depending on the difference of the characteristic between transmission circuit 61 and 62 through the constitution in the figure, but the signal passes twice through the same circuit, the phase characteristic of the transmission circuit is cancelled and the zero phase is realized accurately.

Filed: 1982-06-02
Abstract: PURPOSE:To prevent application of excessive differential pressure to a diaphragm, by contacting the movable part of the diaphragm to a stopper member when the excessive differential pressure is applied, plugging an air hole, and stopping the movement of sealed liquid. CONSTITUTION:When excessive pressure is applied from the side of P1, a semiconductor diaphragm 5 is largely deflected to the lower side. An inner thick part 11 interferes with a ring shaped sealing member 17 and the deflection is suppressed. Then, sealed liquid 4 directly under the semiconductor diaphragm 5 cannot be moved through an air hole 13. The pressure at this part is increased, and the pressure difference between the upper and lower parts of the semiconductor diaphragm 5 becomes zero. Thus the breakdown of the semiconductor 5 can be prevented. Meanwhile, when excessive pressure is applied from the side P2, the semiconductor diaphragm is largely deflected to the upper side. The inner thick part 11 of the semiconductor diaphragm interferes with a ring shaped sealing member 20, and the movement of sealed liquid 3 on the semiconductor diaphragm 5 is stopped. Thus, its breakdown can be prevented.
