Abstract: PURPOSE:To heat a rolled steel with high heat efficiency by a small amount of fuel, in a furnace for continuously heating the rolled steel, by estimating the temperature-rising pattern of the steel to be heated, determining a charge amount of fuel in response to the pattern, and heating each combustion zone. CONSTITUTION:When a steel piece 10 is heatd at a rolling temperature in a continuous annealing furnace comprising a preheating zone 16, a heating zone 20 and a soaking zone 24, the thermal hysteresis of the steel piece 10 to be heated is calculated from the load and size of the steel piece 10, a consumed-fuel amount, a furnace temperature, etc. An estimated combustion-zone load in each of the preheating zone 16, the heating zone 20 and the soaking zone 24 is detected by the rolling pitch of the steel piece 10A to be discharged. A temperature-rising pattern in each combustion zone as a functional value on heat-transmission and heat-balance is forecast from the estimated combustion load, the thermal hysteresis, the discharge temperature of the steel piece and an allowable skid mark value. A fuel-charge amount in response to the temperature-rising pattern is determined to operate the furnace. The temperature-rising pattern in succession is estimated, and a set temperature and a fuel-charge amount in response to the pattern are determined, to continue the operation.

Filed: 1985-01-26
Abstract: PURPOSE:To make larger the quantity of elastic deformation of the elastic member of a cooling device, and at the same time, to facilitate the removal of a semiconductor substrate from the elastic member by a method wherein the elastic member is combined in plural layers in a state that the interior thereof is interconnected with the exterior through numerous high-heat conducting members in the cooling device to prevent the temperature rise of the semiconductor wafer in the ion-implantation process and so forth. CONSTITUTION:A semiconductor substrate 4 is junctioned to a platen 1 to be cooled through an elastic member 11 and a cooling is performed. The elastic member 11 is combined in plural layers in a state that the interior thereof is interconnected with the exterior through numerous high-heat conducting members. Moreover, the elastic member 11 is constituted by a method, wherein a high-heat conducting member, such as a 0.03-nm thick metal foil of copper, aluminum, stainless steel or so forth, is cut in a width of 3mm, the metal foils 11a... cut are woven alternatively in the warp and woof directions in large numbers and the woven ones are superposed several sheets in number. By this way, an adhesive force and an electrostatic force do not act between the semiconductor substrate 4 and the elastic member 11 and the elastic member 11 can be prevented from being damaged. Moreover, even though the quantity of elastic deformation of the elastic member 11 is large and the diameter of the semiconductor substrate 4 is a large one, the semiconductor substrate 4 can be brought into contact with the elastic member 11 sufficiently wide and the cooling effect is good. Moreover, it is also eliminated that the semiconductor substrate 4 is vacuum- attracted to the elastic member 11 and the takeout of the semiconductor substrate 4 from the elastic member 11 is also easy.

Title: Grain size measuring device
Inventor: IWAMOTO KATSUJI
IPC: G01N15/14
Filed: 1979-02-09
Abstract: PURPOSE:To obtain a high-accuracy measuring device with omission of calibration by measuring the grain size by means of the interference fringes of the laser beam. CONSTITUTION:Laser beam 2 sent from laser beam source 1 is divided into the equivalent intensity via half-mirror 3. And one of the divided beams is led directly to beam splitters 5 and 6; while the other is led to splitters 5 and 6 via mirror 4 respectively. Then each laser beam is splitted into two beams. These splitted beams are then focused through lenses 7 and 8, thus obtaining the interference fringes at the measuring region. And when the particle passes through this measuring region, the output waveform is delivered via photoelectric multiplier tubes 9 and 10. And the grain size is decided through signal processor 11. If the resolution is defined as ''resolution=AC amplitude voltage/pedestal (P) voltage'', resolution 0.5 indicates that the grain size is identical to the interference fringes distance. Such measuring region is provided at two areas with the different interference fringes distances secured to each other. Thus the range of a certain grain size can be measured.

Filed: 1984-01-30
Abstract: PURPOSE:To prevent breaks of parts such as disconnection of wires, burning of a motor, or the like and detect disconnection of wires by providing a lock detecting mechanism to prevent lock of a driving system. CONSTITUTION:Though a driving pulley 46 is rotated counterclockwise and a stopper 12 and a stop pin 36 are brought into contact with each other in case of setting of magnifications, a high tension is applied to the tense side of a wire 45 because a motor 58 is not stopped, and therefore, a worm 53 and a worm wheel 51 are locked. Then, when the tension of the wire is applied to a pulley 22, a lever 23 is rotated counterclockwise to turn off a detecting switch 26, and a force exceeding a certain value is not applied to the wire 45 to prevent lock. If the wire 45 is disconnected, the lever 23 is rotated clockwise to turn off the detecting switch 26. Since the motor 58 is stopped by the detecting switch 26 in this manner, lock of the driving system is prevented, and disconnection of the wire and burning of the motor are prevented, and disconnection of the wire is detected.

Abstract: PURPOSE:To attain high density recording to a magnetic tape or to cause the diameter of a revolving head cylinder to be small by drawing a circular arc >=360 deg. in the route of the magnetic tape from a sending reel to a winding reel. CONSTITUTION:The route, in which a magnetic tape 5 goes from a sending reel 6 to a winding reel 7, draws the circle of 360 deg. near a head port.
