Title: Network termination
Inventor: IMAURA TOSHIHIRO
IPC: H04Q5/00
Filed: 1988-08-09
Abstract: PURPOSE:To connect a terminal equipment without provision of a function sending a PB signal automatically by discriminating the kind of equipment when a call request comes from the terminal equipment, sending the PB signal and designating the relevant terminal equipment. CONSTITUTION:In the case of making a call from a terminal equipment 3, a call command added with its own address is sent to a network termination(NWT) 14 from the equipment 3 via a signal transmission line 2. Upon the receipt of the command, the NWT 14 acquires an electric communication line 4 to dial a signal to an external communication network 5 and confirms the kind of the terminal equipment via a terminal equipment address management section 13 from the address of the terminal equipment. When an incoming terminal equipment identification device 6 receiving the signal sends a PB signal to the line 4, the NWT 1 sends the PB signal specified in advance depending on the kind of the terminal equipment requesting a call automatically. Thus, the device 6 connects the external terminal equipment 7 to the line 4 and the talking/communication with the equipment 7 is attained without transmission of the PB signal from the equipment 3.

Abstract: PROBLEM TO BE SOLVED: To prevent the temperature rise of a specified developing device in the midst of the standby state of an image forming device or at the time of selecting a monochrome copying mode by controlling the developing device to rotate when a developing means is in the standby state. SOLUTION: In the case of expecting that the temperature of the C developing device 403, for instance, gets the highest, the temperature rise of the specified developing device is restrained by rotating the device 403 when a machine stands by. When a copying start button is not depressed for five minutes, for instance, the device 403 is rotated by 90 deg. in this method. By repeating such operation that it is rotated by 90 deg. when five minutes elapse further until the copying start button is depressed, failure that only the specified developing device gets in a high-temperature state is eliminated.  In such a case, by rotating a photoreceptor drum 200 simultaneously, a part where the bristles of the developing device abut on the drum 200 is changed every time, so that failure that toner adhering to the drum 200 intrudes in the developing device for another color at the time of next rotation is eliminated.

Title: Reducing method of billet width in continuous casting
Inventor: FUJIKI KOUICHI
IPC: B22D11/04
Filed: 1982-11-13
Abstract: PURPOSE:To maintain the shell near the outlet of a casting mold at a specified thickness or below and to permit smooth change in the billet width in reducing the moving width on the short side of the casting mold under continuous casting by changing the taper angle of the short side and the condition of the binder used and adjusting the cooling speed for the casting mold. CONSTITUTION:The tapered angle of a short side is decreased or the inflow rate or the kind of powder is changed to change the cooling rate of the short side, thereby keeping the shell thickness in the extreme proximity to the outlet of a casting mold at about 1.5mm. or below. The resistance in the movement of the short side is low with such shell thickness even if the short side is quickly moved. The deformation of the shell is smooth and there is no failure of the shell hence no leakage of the molten metal.
