Abstract: PROBLEM TO BE SOLVED: To improve the utilization efficiency of entire facsimile equipment by providing a control means for reading received data stored in a memory and recording them through a recording mechanism based on an instruction from a control panel part during the transmission of transmission data stored in the memory. SOLUTION: A control part 3 constructs a communication line by controlling the network control function of MODEM part 5 based on the instruction inputted from a control panel part 2. In the case of transmission while reading an original through a reading mechanism 6, the received data stored in a memory 9 or data read by a reading part 1 and stored in the memory 9 are read by a recording part 4 and recorded by a recording mechanism 8. Besides, while the reading part 1 reads the data stored in a memory 7 and transmission is executed, the data read by the mechanism 6 are sent to the mechanism 8 and copy is performed while simultaneously executing reading and recording. Otherwise, the received data stored in the memory 9 are read out, the mechanism 9 is operated and only the recording is executed.  Thus, the reading/recording operation, which is not related with line control, can be executed in parallel with transmission.

Filed: 1989-05-30
Abstract: PURPOSE:To eliminate the uneven quality of finish of cooking by providing a control means which determines the execution time for the second process based on the execution time for the first process and the high frequency wave output condition during the first process. CONSTITUTION:If the temperature of the magnetron 4 as detected by a temperature sensor 12 is lower than the predetermined temperature at the time when the magnetron 4 is started for the first process to cook the foodstuff 10 with high frequency waves, the magnetron 4 is operated at its high output level, and, if the temperature is higher, it is operated at the medium output level. Further, even if the operation started with the high output lever, the control circuit 11 switches the inverter circuit 7 to change the output level from high to medium when the temperature becomes higher than the predetermined level in the middle of the first process. When the output level of the gas sensor 9 drops from its maximum value Vmax by an amount alpha.Vmax, i.e., the presence of gas is detected, the first process is terminated and the second process is started wherein the heating is performed under the medium output level. Becomes the control circuit 11 determines the execution time for the second process based on the execution time for the first process and the high frequency wave output condition during the first process, the total amount of heat applied to the foodstuff 10 becomes constant.

Title: Controller for connection to auxiliary storage device
Inventor: YORIMITSU KEIICHI
IPC: G06F13/362
Filed: 1988-06-06
Abstract: PURPOSE:To cause plural controllers to evenly use auxiliary storage devices by deciding the controller to be connected to the auxiliary storage devices based on the device number read by a reading section and previously decided connecting logic when plural connection requests are made at the same time. CONSTITUTION:Upon receiving a coincidence signal from a comparator 26, a lock control section 19 does not allow a controller to make access to a magnetic disk device by sending a lock failure signal to the controller. Upon receiving a discordance signal, on the other hand, the section 19 allows the controller to make access to the magnetic disk device designated by the controller by issuing a lock approve signal. Since the same controller cannot access continuously to the same magnetic disk device in such way, one controller cannot use one magnetic disk device exclusively. Thus even use of magnetic disk devices by each controller can be realized.
