The zirconium plate 15 is processed a pretreatment of growing tendency into hydrogen solid solution or hydrogen compound before its installation. When evacuated such tube as processed in the above, if heated the tube, the zirconium plate 15 emits the hydrogen, providing a reduction ambience in the tube, and an oxidation convertible gas can be promptly evacuated by forced replacement. After a heating, residual hydrogen of the zirconium plate 15 is made emitting by the method of high frequency heating, and a conventional evacuation work is operated. In this way, because a gas discharge in the last half of process can be made at faster speed and decreased, a work of efficient evacuation can be performed.

Title: Signal disconnection detection system
Inventor: HAYASHI AKIHIKO
IPC: H04B10/07
Filed: 1994-01-27
Abstract: PURPOSE:To stably perform a signal disconnection detection by performing a phase modulation for the output of an equalization amplifier part by the modulation signal of a fixed frequency. CONSTITUTION:When an input signal exists in an equalization amplifier part 100, a phase modulation is performed for the output by the modulation signal of a fixed frequency f1. As a result, a signal for which a pulse width modulation is performed, for instance, can be obtained from a phase modulation part 140. By passing this modulated signal through a filter part 160, a signal of a fixed amplitude including frequency f1 component is outputted, the presence of the signal is decided in a signal disconnection detection part 180. When the output noise of the amplifier part 100 exists at the time of no input, a phase modulation signal can not be obtained even if a modulation is performed by the modulation signal of the f1 in a modulation part 140. Therefore, the f1 component is not included in the output of the filter part 160, the output amplitude is small and a signal disconnection can be stably detected in a detection part 180.

Filed: 1980-01-25
Abstract: PURPOSE:To vary the division ratio of a programmable divider, by connecting previously an up-down counter to the programmable divider and varying the contents of the up-down counter. CONSTITUTION:In case the signal of fi=kHz is applied to the input of the phase detector 1, the frequency fO of the VCO3 is changed into 5MHz. For this purpose, the division ratio is set as N=5,000 for the programmable divider 6. The thumb- wheel switch of the division ratio setter 5 is set at 5,000, and the switch 11 is connected to the LOW side. In such way, 5,000 is stored in the memory 6 and then applied to the programmable divider 4 to obtain a division ratio of 5,000. To obtain a frequency higher than the set 5MHz by 10kHz, the switch 9 is connected 10 times to the LOW side. As a result, a signal of 10 pulses is generated from the monostable multivibrator 7 and applied to the UP input terminal of the memory 6. Thus the memory 6 receives a 10-addition.

Abstract: PURPOSE:To independently register sounds at an information buzzer and to enhance the operating property of an apparatus by a method wherein, when any abnormality is caused at the apparatus, an operator is informed of the abnormality via the information buzzer on the basis of the registered sounds stored in a storage device. CONSTITUTION:When a switch part used to set surroundings is touched, a screen used to set the surroundings is displayed. An operating switch used to set a buzzer is touched; a screen used to set the buzzer is displayed. The message sound of the buzzer 42 is set by using the screen. Whenever operating switch parts corresponding to individual pieces of data on the screen are touched, the message sound is changed in the order of a continuous sound, an intermittent sound, a registered sound and a cutoff. As a result, it is possible to arbitrarily set the intermittent sound e.g. in the case of the abnormality, and the sound is stored in a RAM 34. When e.g. a test key at the lower left of the sensor is pressed, registered sounds are informed by using the two-cycle buzzer 42, and an operator can confirm them. When the independent registered sounds are used, the operator can distinguish them from those of a line apparatus of which he is in charge and can discriminate the sounds from those of other line apparatuses.
