Filed: 1983-03-22
Abstract: PURPOSE:To accelerate the switching speed by reversely operating the conductions of a main static induction (SI) thyristor and an auxiliary SI thyristor, and extinguishing the main SI thyristor by the discharging current of a capacitor flowed when the auxiliary thyristor is conducted. CONSTITUTION:When a turn ON switch 8 is closed, the gate of the SI thyristor 1 is forwardly biased, and the gate of an SI thyristor 19 is reversely biased. In the meantime, a capacitor 12' is charged by an auxiliary power source 18. When the switch 8 is opened and a turn OFF switch 9 is closed, the thyristor 19 is turned ON, the charge of the capacitor 12' is discharged, the stored carrier of the thyristor 1 is swept out to recover the junction between the cathode and the gate. When the resistance value of the resistor 14 is selected to sufficiently smaller value than the resistance value of the resistor 14, the voltage of the power source 11 is effectively supplied as reverse bias to the gate of the thyristor 1.

IPC: B29C61/00
Filed: 1979-04-16
Abstract: PURPOSE: To produce a napped sheet suitable used as a wall and ceiling covering material, in which the condition of naps varies with the shape and distribution of crimps on the sheet, by pressing against a rotary heating body a film of a thermoplastic resin and a substrate material consisting of an unwoven cloth which has been crimped to form regularly spaced recesses therein, and tearing off the substrate material with the film fused thereon from the rotary body.  
     CONSTITUTION: A film 2 of a thermoplastic resin and a substrate material 3 are pressed against a heating roll 1 as the film 2 and substrate material 3 are moved in layer. The film 2 is molten to be sticked to the surfaces of the roll 1 and substrate material 3. Since the substrate material 3 has been crimped to form regularly spaced recesses 12 therein with the remaining part in a flat state, the flat portion of the substrate material 3 is fused to the film 2 but the recesses 12 are not. When the substrate material 3 is then torn off from the roll 1, the film 2 gats stringy between the roll 1 and substrate material 3. Thus, the resin fused to the substrate material 3 turns to be string-like naps 13 which are substantially uprightly extended. The air from an air ejection unit 4 runs through the substrate material 3 to allow the naps 13 to be cooled as they are. The napped sheet 11 are annealed by a heating roll 5, tensed by a tension roll 6 and taken up around a take-up roll 9.

Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To make a crosstalk distribution min., for satisfying a multi-media traffic request and to increase system capacitance by dividing a long packet in terms of a burst in data into shorter units, that is, packet slots. SOLUTION: The number of fixed bits are selected, in order to utilize the characteristic of a packet slot distributing pattern, and a packet frame 41 is constituted. The frame 41 is smaller than the normal packet length. Data is group-converted into smaller sets, that is, to the packet slots 42. Since channel band width is considerably larger than the velocity of an information originating source, the respective packet slots are compressed to a shorter time as expressed by communication medium velocity 43. In this case, between any kind of two packet slots originating from a single originating source whatsoever, time at which data is not transmitted from the originating source exists. Thus, the packet slot is transmitted in time, which is decided by the packet slot distributing pattern.

Title: Moving layer incinerator control
Inventor: TOSHIBE HIROSHI
IPC: F23G5/30
Filed: 1978-04-24
Abstract: PURPOSE: To control the incinerator temperature on the base of the amount of heat and water contained in the exhausted substance which includes nitrogen oxides such as EP ashes and the time constant of the moving layer incinerator, thereby burning up the substance to be disposed in a natural condition without producing any nitrogen oxides.  
     CONSTITUTION: The amount of heat and water contained in EP ashes is measured respectively by meters 17 and 18. On the other hand, the temperature in the layer and an air tower of an incinerator 1 is also measured respectively by meters 12 and 13. The results of both the measurements are sent to a regulating box 14, which compares the results successively with the time constant of the incinerator temperature. If the temperature in the layer is maintained, for example, about 570W650°C and the temperature in the air tower is about 670W740°C, the nitrogen compound included in the EP ashes dissolves without forming nitrogen oxides. Accordingly, if the incinerator temperature is maintained around these values at the respective parts by controlling the fuel supply, the cooling water atomization and the combustion air amount on the base of the signal from the regulating box 14, the EP ashes can be burnt up in a natural condition.
