Title: Gas burner capable of preventing shortage of oxygen
Inventor: TAKIGAWA OSAMU
IPC: F23N5/24
Filed: 1980-06-06
Abstract: PURPOSE:To make it possible to detect an oxygen deficiency and to simplify the structure of the burner by a method whrerin an oxygen sensor is formed by an oxygen ion conductive solid electrolytic plate having oxidizing catalytic electrodes attached to both front and rear surfaces thereof. CONSTITUTION:The oxygen sensor 20 comprises the oxygen ion conductive solid electrolytic plate, for example, a zirconic disk 21 stabilized by the addition  of 8mol% of oxidized yttrium, the electrodes 2 and 3 made of porous platinum and attached to both upper and rear surfaces of the solid electrolytic plate in opposite relationship with each other and lead wires 4 and 5 connected to the electrodes. Further, protective layers 14 and 15 are formed on the surfaces of the electrodes 2 and 3, respectively, by spraying zirconic powder. The oxygen sensor 20 thus formed is used in a waste gas atmosphere at a position at which the flame of the burner first comes into contact with the sensor 20 when there is a shortage of oxygen at the time of ordinary combustion. Thus, when the flame of the burner contacts with the sensor 20 in an oxygen deficiency, the sensor 20 generates an output according to which a valve 7 in a gas passage 9 is closed through a signal processor 6, to thereby extinguish the fire of the burner.

Title: Small-diameter waveform forming roll, and single facer equipped with adjustable winding arm device
Inventor: MARSCHKE CARL R
IPC: B31F1/28
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a single facer, in which the influence of a labyrinth is removed and, at the same time, the deflection of waveform forming rolls can be prevented from developing with a simple constitution. SOLUTION: Waveform forming nips are formed by means of nips 16 between a small-diameter waveform forming roll 12 and a large-diameter waveform forming roll 11. In order to ensure a necessary waveform forming nip pressure and to prevent the small-diameter waveform forming roll 12 from deflecting to the direction normal to its axis line, a pressingly rotary roll device 36 is arranged so as to apply a downward sloping pressing force to the small-diameter waveform forming roll 12. The pressingly rotary roll device 36 consists of a pair of free rolls 38 and a pressing belt 42 spanned between a pair of the free rolls 38.

Abstract: PURPOSE:To obtain a PLL circuit hardly affected by the missing of a disturbance signal, by providing a circuit means for detecting the period when an incoming signal is absent over a prescribed time and a circuit means for suppressing the feedback of the phase difference to a voltage controlled oscillator in accordance with a detection signal from the circuit means. CONSTITUTION:Output signals 20, 21 of gates 13, 14 are supplied to a control input of a voltage controlled oscillator 15 as a deceleration signal and an acceleration signal, respectively. When a tachogenerator pulse 5 is generated normally, the deceleration signal 20 corresponding to the phase difference between the tachogenerator pulse 5 and a signal 6 is supplied to the voltage controlled oscillator 15, which is controlled so that the oscillating frequency is reduced. When the tachogenerator pulse 5 is missing, a counter 16 stops the count operation and no output signal 22 is generated. Thus, the deceleration signal 20 (of course, the acceleration signal 21) is suppressed with the gate 13 and not generated, and the voltage controlled oscillator 15 keeps the oscillating frequency just before.
