Title: Gradation compensating device
Inventor: WATANABE HIDEAKI
IPC: H04N1/40
Filed: 1982-03-26
Abstract: PURPOSE:To reduce the variance of density due to the difference of heat dissipating  characteristics, by changing in stepwise the relation between the density level of an input picture signal and the electric energy which is applied to a resistance element of a  heat generating resistor train at the block at the center part and the blocks at both  ends of the resistor train respectively. CONSTITUTION:For a heat-sensitive recording head 1, the heat printing heat generating  resistors 1a are arranged in a parallel and linear form and then divided into 5 blocks  of (m) dots each to form a matrix of (m) rows and 5 columns. One side of (m) units of  resistors 1a is connected to 5 common electrodes 1b1-1b5 respectively; while the other  side of the resistors 1a receives application of the picture information via a switching  circuit 2 and shift registers 3a-3d. Then a picture signal containing a half tone is supplied to a comparator group 5 through an input terminal 4. The group 5 discriminates  the picture signal into the threshold value of plural stages in response to the amplitude  of the picture signal and gives them to an encoder 6. Then a coded picture signal is  stored in a data RAM 8. The gradation designating data delivered from a gradation designating ROM 7 are compared by a comparator 9 simultaneously with the reading  of the RAM 8 and then applied to the registers 3a-3d. As a result, the variance of  density due to the difference of heat dissipating characteristics can be reduced.

Abstract: PURPOSE:To stabilize operations and reduce the cost with a simple constitution, by providing an analogue phase comparator as the phase comparator and by providing a pulse circuit in the feedback circuit, in PLL voltage control crystal oscillator VCXO. CONSTITUTION:A reference input frequency is input to terminal 10, and the output of analogue phase comparator 12 is caused to pass through LPF 14, and VCXO 16 is controlled by the DC voltage of the output, and the oscillation output is output from terminal 18. The output of VCXO 16 is divided by fixed frequency divider 19 of frequency division ratio N, and a square wave of prescribed pulse width vs period t/T of 1/2 of less is generated by pulse circuit 21 and is input to comparator 12. The square wave of circuit 21 includes higher harmonic; and if the upper limit frequency of higher harmonic is defined as t/T=1/2N, the higher harmonic group of a level of 64% or more of the fundamental wave is obtained up to a frequency N-number times as high as the fundamental frequency. Consequently, a PLL-VCXO variable multiplier which is synchronized with the reference input frequency N/M (a positive integer, N>M) times as high as the oscillation frequency of VCXO correctly can be obtained with a simple circuit.

Abstract: PURPOSE:To efficiently remove volatile substances contained in a polymer by heating a specific amt. of the polymer into a warm water tank and then feeding a specific amt. of an inert gas into the warm water via a sparger to keep the polymer in a fluid state. CONSTITUTION:A polymer (e.g. a styrene/acrylonitrile copolymer) contg. volatile substances such as a monomer(s) (e.g. styrene), a solvent (e.g. hexane) and a catalyst is fed into a warm water tank provided that the polymer to warm water wt. ratio is in the range of 1:1 to 1:10. An inert gas (e.g. air) passed through a sparger is then fed into the warm water, provided that the wt. ratio of the inert gas to the polymer is 0.5 to 20. Thus, the polymer is kept in a fluid state. According to the foregoing procedure, the volatile substances in the polymer can be removed in a short period of time.

Title: Graphite-made nozzle for continuous casting
Inventor: MINOURA SEIJI
IPC: B22D41/54
Filed: 1988-03-01
Abstract: PURPOSE:To improve the service life and durability of a nozzle and also to stabilize a continuous casting product having high quality by coating pyrolytic carbon film on surface of graphite base material. CONSTITUTION:As the general graphite material has many fault parts in constructive structure, oxidizing reaction and melting into molten metal from there are promoted and this becomes a reason, why the service life of the nozzle for continuous casting is shortened. By coating the pyrolytic carbon film on this graphic base material, as the pyrolytic carbon film has very close construction having entirely no porocity and also highly developed crystal structure form having a little fault, the development of the problems is restrained. Further, as substantially it is carbonic quality, it has also self-lubricating property, and it is possible to execute smooth metal casting. Therefore, compared with the conventional nozzle, it has more improved service life and excellent durability and at the same time, the continuous casting product having high quality can be stably produced.
