Title: Method of controlling charging of coal in coke-charging vehicle for coke oven
Inventor: YAMAMOTO TANEZOU
IPC: C10B37/00
Filed: 1985-07-17
Abstract: PURPOSE:To completely avoid troubles with coal clogging in the coal-charging path, by detecting a sign of coal clogging in the coal-charging path by means of a detector provided in a subsidiary hopper to automatically stop the coal delivery and start the delivery again. CONSTITUTION:A table feeder 11 of a delivery apparatus 10 is rotated to feed coal 15, contained in a hopper 4, through a delivery port 14, a subsidiary hopper 7 and a sleeve 9 into a carbonization chamber of a coke oven 2. If the coal 15 stays in the hopper 7 and results in the appearance of coal at level 15b, it is detected as a sign of clogging by a sensor 18 at the end of a detector 19 provided in the hopper 7. The detection signal is transmitted to a control apparatus 20. This lights a lamp 22 on a display board 21. If the detection is continued for a predetermined period of time, the signal is also transmitted to a driving motor 13 of the apparatus 10, thereby causing the motor 13 to be stopped. When the sensor 18 is apart from the level 15b of coal for a predetermined period of time, the detector switches off, and the motor 13 starts again, thus delivering the coal 15.

Title: Heat exchanger of silicon carbide
Inventor: NAGASHIMA HIDEO
IPC: F28F21/04
Filed: 1982-09-10
Abstract: PURPOSE:To increase acid resistance or intensity of a heat exchanger especially in high temperature, by using silicon carbide fiber, which coexists with metallic silicon. CONSTITUTION:Material containing 5-65wt% of fibroid silicon carbide and 6.5- 35wt% of metallic silicon is used as a silicon carbide material. Silicon carbide fibre has extremely high intensity by itself. Trial is made to blend it with silicon carbide powder and to utilize it as a material of high intensity, but pressure- tight material is hard to be obtainable. Coexistence of metallic silicon makes it possible to obtain the one of high intensity and of pressure-tight. An effect of metallic silicon is not recognized if it is 6.5wt%, but in case of more than 35wt%, the quantity of silicon carbide is relatively lowered, and it seems that problems will be caused in heat resistant and corrosion resistant properties of the material.

Title: Commutation ticket issuing device
Inventor: SAKURAI SUMIO
IPC: G07B1/00
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To prevent the communication ticket unclear in printed name from being issued erroneously by dividing the pixel data of a name column, judging a density and bias and performing correction processings such as a re-read processing, the input processing of the name by KATAKANA (square form of Japanese syllabary) and a centering processing, etc. SOLUTION: This commutation ticket issuing device 1 is provided with a CPU 20, a name read part 22, a memory 21 and a commutation ticket issuing part 24. The name column where the name is written on an application form is read and converted into black-and-white pixel data in the name read part 22 and whether or not the density of black dots in the pixel data of the name column is normal is judged in the CPU 20. Also, the bias of the name is judged. In the case of judging that the density of a name image is abnormal, the CPU 20 performs the re-read processing or the input processing of the name by the KATAKANA and performs the centering processing when the bias of the name is judged. Thus, the name on the commutation ticket is not too thick or too thin and is not biased, the printed name is clearly read to prevent the commutation thicket unclear in the printed name from being issued.
