Title: Memory interface and image data compressing device
Inventor: MIYAZAWA TOMOJI
IPC: H04N19/88
Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To flexibly cope with an SDRAM of a different specification used for image data compression processing. SOLUTION: Image data fed to a signal processing section 200 in the inside of an ASIC 201 is written in an external main memory 160 consisting of, e.g. an SDRAM to the ASIC 201 via an SDRAM I/F 164. The signal processing section 200 accesses the memory 160 and applies compression coding to the image data by using the memory 160. A CPU 127 supplies a parameter relating to timing of the SDRAM 160 to the SDRAM I/F 164 via a CPU I/F 126 based on the received setting information. The SDRAM I/F 164 controls access to the memory 160 in an access timing on the basis of the supplied parameter. Since the timing parameter of the memory 160 is supplied from the outside of the ASIC 201, the ASIC 201 can flexibly cope with the memory 160 of a different kind.

Abstract: A method for the control of the proportion of two gases which are delivered to a mixed gas line for use for example in a respiratory breathing apparatus in which the gases are delivered to a mixed gas line from a pressure control vessel, comprises continuously monitoring the pressure in the control vessel and when the pressure therein is at an initial predetermined pressure admitting a first gas into the pressure control vessel until the pressure therein increases to a predetermined higher pressure and then stopping the admission of the first gas and initiating the admitting of a second gas into the pressure control vessel, continuing to admit the second gas until a predetermined additional higher pressure is achieved in the pressure control vessel, discontinuing the admission of the second gas when the predetermined additional higher pressure is reached and initiating the withdrawal of the mixed gas through the mixed gas line, continuing to withdraw the mixed gas through the mixed gas line until an initial pressure is again reached in the pressure control vessel at which time the complete process is repeated again. The apparatus includes a first control valve in a first gas supply line to the pressure vessel and a second control valve in a second gas supply line to the pressure control vessel. A third control valve is arranged in a mixed gas delivery line which connects the pressure vessel. All of the three valves are connected by a control device which is responsive to the pressure in the pressure vessel and the individual control valves are set for opening and closing at different control pressures so that the inflow of the first and second gases and the delivery of the mixed gases will be continuously controlled thereby.

An electrolyte is supplied to the passage between the drum 1 and the anodes 3 and 4, and a specified voltage is maintained by a rectifier 5. As the drum 1 rotates, copper is electrodeposited from the electrolyte, and the crude foil in specified thickness is released by an appropriate releasing means and wound up. The set positions of the discrete foil thickness uniformizing split anodes 4 are separately controlled. Consequently, the electrolytic current density is adjusted, and the thickness of the electrolytic copper foil produced is uniformized.
