Abstract: A method of dissolving a rubber continuously to form a raw material for the production of rubber-modified polymer, by dissolving a rubber in a monomer liquid dissolving the rubber and capable of reacting with the rubber in the presence or absence of a solvent. Pieces of rubber are fed continuously to a dissolution tank to allow the dissolved rubber and the undissolved rubber to coexist in the dissolution tank, wherein the concentration of the dissolved rubber is the concentration at which the feeding to the reactor is made, and the quantity of the undissolved rubber present in the dissolution tank is at most the quantity that prevents pieces of the undissolved rubber from sticking to one another to form larger rubber masses. The time required for dissolution can be shortened, and the size of a dissolution tank can be made smaller, compared with the conventional methods.

Filed: 1998-05-21
Granted: 2000-01-21
Abstract: The invention relates to a kind of serial data receiving and transmitting between communication circuits of functional modules formed in integrated circuit. The serial data communication circuit comprises an encoder used to generate a pulse signal representing the data with specific pulse duration period; a decoder used to restore the received pulse signal of encoder to the data; the data wire, used to connect one output of the encoder with a data input of the decoder; and a controller, used to add a specific data value to the data value to be transmitted and to substrate a specific data value from the received data value. Especially, the duration period of pulse signal is composed of the first pulse duration with a specific time period and the second pulse duration with the sum of unit time periods. Besides, the specific data associated with the first pulse duration represents the beginning of that pulse signal. And, the time period of the first pulse duration is longer than the unit time period of the second pulse duration. Because the serial data transmitted by the data wire has unified pulse format, it can effectively avoid EMI during data transmission and the electromagnetic radiation can be greatly reduced and eliminating the noise problem. Furthermore, according to this invention, when the receiver simultaneously receives one pulse data signal and its complementary pulse data signal and when the two recovered data are the same, it will send back an acknowledged signal to the transmitter so as to provide simple data verification and debugging method for data transmission. So, during the serial communication, it can avoid the error data transmission caused by external noise.

Further, since ceramic material 13 is heated while it is placed on holder 14, it is possible to prevent ceramic material 13 from fracturing. Furthermore, since the pressure to be applied at the time of pressure-welding is not more than 1kg/mm<SP>2</SP>, it is possible to prevent ceramic material 13 from fracturing. Accordingly, it is possible to manufacture high quality combination material of metal foil and ceramic 19 and metal foil laminated ceramic substrate 20 with a high productivity.

Granted: 2001-05-01
Abstract: This invention provides a kind of radio control device. The device has D/R function of simple operation change rate without damaging the operating characteristic of the operation-rod. The radio control device of this invention is set in the way that the rate, which determines the relationship between the operating quantity of the operation-rod and the action quantity of servomotor, can be changed at the changing point, which is arbitrarily set, within the range of operating quantity for the operation-rod. The rate 1 is equal to 100% and the rate 2 is equal to 60%. The setting point 1 is set at the position with 65% degree of the maximum quantity in the operating direction (or the lower direction). The setting point 2 is set at the position with 85% degree of the maximum quantity in the left direction (or the upper direction) of the operating quantity. The operating quantity of the operation-rod has smaller range at the rate 2, in which the effect of rudder wing is blunter, and becomes the rate 1 when surpassing the setting point, in which the effect of rudder wing becomes better. The device of this invention can generate larger servo operating quantity by using less operation of operation-rod.
