Filed: 1985-08-09
Abstract: PURPOSE:To attain a proper binary-coding processing with a few memories and simple hardware by applying operation of frequencies at a prescribed level before and after detection as well as prescribed detected frequencies in forming a histogram. CONSTITUTION:When an optical system is subject to forward scanning and a coordinate on an original platen is detected, a CPU 211 calculates an area to sample a peak value for deciding a slice level for binary-coding from a coordinate data. In starting reversing, after a main scanning line synchronizing signal is counted by a prescribed distance, white/black peak values are detected to form a white peak histogram and a black peak histogram by using white/ black peak histogram areas prepared in a RAM 213. Then density value representing the maximum frequency of the black peak histogram and the white peak histogram are decided as the information part and the back ground part of an original and the median of them in decided as the slice level. A comparator 210 uses the said slice level to binary-code a picture signal from a latch 203 and to output the result.

Filed: 1986-07-25
Abstract: PURPOSE:To properly protect a traveling-wave tube, by changing a helix-current alarm detection point on the basis of time passing after anode voltage is impressed on the traveling-wave tube. CONSTITUTION:When anode voltage is impressed on a traveling-wave tube, an alarm detection value 11 of helix current larger than rush current is set up in a helix-current alarm control circuit 6. When the anode voltage of the traveling-wave tube 2 rises to a normal value to become in a normal state, the helix current actually flows in the helix part. In this cace, an anode-voltage control signal of a control circuit 4 is inputted to a timer circuit 5, and then after the timing value in the timer circuit 5, that is, after the time T equal to the rising time of anode voltage, the output of the timer is sent out to the helix-current alarm control circuit 6 so that a value on an alarm detection level is changed into an alarm detection value 12 which is lower than the alarm detection value 11. Such control of changing the alarm detection level enables the traveling-wave tube 2 to be properly protected.

CONSTITUTION: A medium flow 17 entering an inlet chamber 5 is distributed into two shunts 18 and 19 and the shunt 18 flows out into an outlet chamber 6 from a heat exchanging tube 2 and then, into a mixing tube 13 through a cylinder 12 via an opening 14. The shunt 18 is mixed in the mixing tube 13 with the shunt 19 yet to be cooled guided through a shunt pipe 11. The ratio in quantity between the shunts 18 and 19 and the temperature of the mixed medium flow 20 flowing out through an outlet joint 8 are adjusted by a control plate 16. The shunt 19 is discharged directly without contacting the outlet chamber 6 via the outlet joint 8. Therefore, when the medium exhibits a corrosive action within a specified range, it is only sufficient to build the shunt pipe 11, the cylinder 12 and the mixing tube 13 alone up of an anticorrosive material.

In this case, the air outlet frame 9 is formed by a resin composition containing crystalline polyolefin and an inorganic support material, thus preventing the crack of the air outlet frame 9 being caused by allowing chemicals being used for the heat exchanger 7 to drop with drain or by allowing a washing liquid containing, for example, a surface-active agent for washing the heat exchanger 7 to come into contact.  Also, crystallizability polypropylene and a glass fiber should be used as the crystalline polyolefin and the inorganic support material, respectively.
