Title: Data transmission system
Inventor: MAEDA TETSUO
IPC: H04L1/00
Filed: 1987-01-28
Abstract: PURPOSE:To improve the reliability of a transmission data by utilizing a vacant bit or a vacant frame effectively, by generating an error detection code from the transmission data, inserting the said error detection code in the vacant bit or the vacant frame, and sending it with the transmission data. CONSTITUTION:A multiplexing part 11 generates a fast multiplexed data by multiplexing an inputted slow data, and outputs it to an error detection code generating part 12 and a frame generating part 13. The error detection code generating part 12 calculates the error detection code ERR from an inputted fast multiplexed data, and sends it to the frame generating part 13. The frame generating part 13 generates a transmission fast multiplexed data by inserting the error detection code ERR into the vacant frame, and sends it to the H channel of a fast digital line 3. Thus, by inserting and transmitting the error detection code ERR in the vacant frame, it is possible to detect the error of the transmission data at a reception side without lowering multiplexing efficiency, thereby, to improve the reliability of the transmission data.

Abstract: PURPOSE:To shorten the priming time of a circulation pump in a circulation circuit and to reduce noise generated by air locks in the circulation pump when water in a bath tub is circulated, and to prevent a phenomenon that a switch valve cannot be opened because of freezing of water drops even when outdoor temperature goes down below the freezing point. CONSTITUTION:A circulation pump 38 to circulate bath tub water 37 for an additional heating, a switch valve 42 to open and close a circulation circuit 36, and a controller 49 to control the opening and the closing of the switch valve 42 are provided. The controller 49 controls the switch valve 42 to be closed, when temperature keeping is on stand-by, the bath tub water 37 exists in the bath tub, and freezing preventing operation is on stand-by, and to be opened, when the bath tub water is in circulation, and therefore it does not exist in the bath tub, and freezing preventing operation is on stand-by. By this priming time at a start of circulation of the bath tub water 37 can be shortened and air locks can be prevented, so that motion noise can be reduced. Also the switch valve 42 can be free from freezing.

Abstract: PURPOSE: To minimize the retardation time of an address line, and to accelerate the arithmetical speed of the static type RAM by making the thickness of a gate film of an MOSFET for selecting cells in a memory matrix thicker than that of a gate film of an FET for a peripheral circuit.  
     CONSTITUTION: A flip-flop circuit is formed by an inverter consisting of an FET T 1  and a resistor L 1  and an inverter composed of a T 2  and an L 2 , and used as a memory cell. The FETs T 3 , T 4  for selecting each cell Mij arranged in matrix- shaped forms are connected to a line decoder 11 through the address lines consiting of the poly Si wiring of a gate electrode, but the acceleration of arithmetical speed is limited by the distribution CR time constant of the address lines. Consequently, a process such as a gate oxidizing process is formed in two stages or a process such as a gate electrode forming process is made another process, and the thickness of the gate films of the T 3  and the T 4  is shaped in thickness (to value such as approximately double) thicker than that of the gate films of other FETs. Accordingly, the access time of the static RAM can be increased to the high speed of approximately 50nsec.

Abstract: PROBLEM TO BE SOLVED: To provide an image forming device capable of always and stably maintaining the formation of an image of high quality, regardless of the kind of paper or the carrying speed of a paper sheet. SOLUTION: A driven rotary roller 29 and an attracting/charging roller 31 holds the fed paper P together with a carrying belt 25, an attracting bias voltage corresponding to a set mode is applied to the paper P from the attracting/charging roller 31 and the paper P is carried. A toner image is formed (development) on an electrostatic latent image on the periphery of a photoreceptor drum 21 by the developing roller 24-2 of a developing unit 24. A transfer brush 26 applies a transfer current outputted from transfer bias supply 26-1 to the paper P with the carrying belt 25. When the paper P is an OHP sheet, the carrying speed is one-half that of a plain paper and the transfer current is applied for a time twice as long as that of the plain paper. A transfer potential does not become too high because a potential by charge is one-half that of the plain paper.  Therefore, the toner image on the drum 21 is transferred in a stable state with the transfer current and a fixing time is made longer, so that the image with high transparency can be obtained.
