Filed: 1989-03-27
Abstract: PURPOSE:To obtain a satisfactory distortion characteristic and a low energy consumption characteristic with simple circuit configuration by using an FET as a frequency converting element, inputting an RF signal to a source, inputting a local oscillation signal to a gate and outputting the signals from a drain. CONSTITUTION:The local oscillation signal to be generated by a local signal generator is inputted from a local oscillation input terminal 7 through an impedance matching circuit 10 to a second gate 2 of a dual gate FET 1. The RF signal is inputted from an RF input terminal through an antenna and a band pass filter to a source terminal 5. The RF signal is modulated by the frequency component of the local oscillation signal inputted to the second gate 2 according to the non-linearity characteristic of the FET and as the differential component of both frequencies, a IF signal is obtained from a drain terminal 4. The source terminal 5 is biased to a positive potential by a source bias resistor 32 in the manner of a direct current. However, the value of the source terminal is selected so as to obtain desired conversion gain, distortion and energy consumption characteristic together with the source bias.

Abstract: PURPOSE:To make it possible to perform the setting of a margin by the simple operation of switches, by mounting a margin data storing apparatus for storing the data showing a position, where a carriage is stopped, as margin data according to right and left margin setting modes. CONSTITUTION:When a right margin is set after paper 11 was mounted to the arbitrary position of a platen 12, a right margin setting mode switch 15 is turned ON. Next, a carriage rightward moving switch 18 is pushed to allow a carriage 13 to move to the right to stop the same at an objective position. When the carriage 13 exceeds the objective position, a carriage leftward moving switch 17 is pushed to return the carriage 13 to the left. The carriage 13 is stopped at the objective position on paper 11 by this operation and a margin setting switch 16 is pushed to perform the setting of the right margin. When a left margin is set, a left margin setting switch 14 is turned ON. The operation on and after is same to the setting operation of the right margin. The order of margins to be set is arbitrary.

Title: Semiconductor storage device
Inventor: TOYOMOTO HIDEHARU
IPC: G11C11/406
Filed: 1989-03-27
Abstract: PURPOSE:To enable high-speed operation by providing an wait signal generation circuit to send an wait signal which sets an external control circuit in a standby state for a fixed time at the time of refresh operation. CONSTITUTION:When a refresh request is generated during the normal operation, this cycle is finished by an arbitration circuit 10. When an access is given from a CPU, an wait signal generation circuit 16 outputs the wait signal through an wait signal output buffer 17 to the CPU since a refresh request signal to be sent from the circuit 10 is transmitted to the circuit 16 as well. Thus, the CPU is set in the standby state for the fixed time. The refresh interval of a DRAM is generally once 16mus. However, since the CPU executes an wait cycle only at the time of the refresh operation, an access time at the time of the normal operation can be shortened and the high-speed operation can be executed.

Abstract: PURPOSE:To make an output voltage constant stably within a wide range from a light load to a rated load by switching a switching element through separately excited oscillation. CONSTITUTION:The ON signal of a switching means 8 is controlled by an on-control means 18, controlled by the output frequency of the voltage control oscillator 17 of power-factor improvement circuits 10, 14-18. The OFF signal of the switching means 8 is controlled by the threshold value of an output obtained by the product of an output, generated by the differential amplification of a reference voltage and the output voltages of chopper circuits 8, 12, 13, 15, 19, by the input voltages of the chopper circuits, while the OFF signal is generated by an off-control means 15 when the value of a current, conducted through the switching means 3, has exceeded the threshold value and the switching means 8 is put OFF. The output frequency of a voltage control oscilla tor 17 is controlled by the output current of the chopper circuits since the con tact input of the current, conducted through the switching means 8, is a current proportional to the output current of the chopper circuits 8, 12, 13, 15, 19.
