Title: Half-duplex communication system in direct memory access control circuit
Inventor: USUI FUMIO
IPC: G06F13/00
Filed: 1986-12-12
Abstract: PURPOSE:To reduce the load on a processor and to remove the restriction to the number of interruption levels by switching one channel in a direct memory access (DMA) control circuit on time-division basis and controlling data transfer of half-duplex communication. CONSTITUTION:An instruction decoding circuit 8 in the DMA control circuit 7 reads out and analyzes an instruction from an instruction table 9 in a memory 5, instructs a channel 10 based on a transmission data transfer request sent from a serial communication control circuit 6 and inputted through the channel 10 to send transmission data from the memory 5 to the circuit 6, and after completing the transfer of the prescribed volume of data, reads out an instruction from an instruction table 9, switches the circuit 6 to a receiving state, and stores the received data in the memory 5. Consequently, a processor 1 can be allowed to omit transmission/reception switching control for the circuit 6. Thereby, only one channel may be used, the load on the processor 1 can be reduced and the restriction to the number of interruption levels in the processor 1 can be eliminated.

Abstract: PURPOSE:To accurately perform the test for residual capacity of a lead battery by giving an alarm in accordance with the output stoppage of a discharge amount selection part and stopping the alarm in accordance with the output stoppage of a delayed output from the discharge amount selection part. CONSTITUTION:An alarm part 6 is actuated with an OFF condition of the output V3 of the discharge amount selection part 5, and after an alarm device 62 consisting of a buzzer, etc., is made to operate during the prescribed delay time (taz) decided by a delay circuit 61, the discharge is stopped by means of stopping the operation of a relay RY to open the contacts (ry). That is, when the output V3 is turned on, a capacitor C1 is charged to generate the output V4, thereby the output V6 is generated from a comparator 63, but when the V2 is made to be a low level, the alarm device 62 is made to start the operation. At the same time, V4 is lowered in accordance with a certain time constant, and when it goes down lower than a threshold value V5, the output V6 is made to be OFF by the comparator 63. The operation of the alarm device 62 is thereby stopped and also the output V7 added with the outputs V2 and V6 is made to be OFF.

Title: Semiconductor device
Inventor: ARAYA YUKIHIRO
IPC: H03K19/003
Filed: 1987-11-26
Abstract: PURPOSE:To prevent a current from flowing to a board of a device and to improve the output switching characteristic by using an npn transistor(TR) of opposite connection as an npn TR for controlling an output TR at a ground point. CONSTITUTION:With an output at H level, an externally mounted output TR Q4 is turned off, that is, externally mounted output TR controlling pnp TRs Q1, Q2 are respectively turned on and off and an externally mounted output TR control opposite connection TR Q3 is turned on. With an output at L level, the respective TRs are in the opposite switching state. Through the constitution above, since the TR Q3 is connected opposite, it is not required to give a large current to turn on and off the TR Q4 and unsharpened leading and trailing of the output waveform is decreased. Thus, the switching characteristic is improved. Even when the output terminal 2 goes to a negative potential when the output circuit is turned off, the current flowing to the semiconductor substrate is prevented.

Filed: 1998-10-20
Abstract: PROBLEM TO BE SOLVED: To prevent the temperature drift of a Mach-Zehnder type photosynthesis phase difference for transmitting a high-frequency signal by using an optical fiber. SOLUTION: An unbalance Mach-Zehnder type external optical modulator 3 subjects the optical carrier wave from a light source 1 to double sideband modulation suppressing the carrier wave by the high-frequency signal of a frequency f and outputs the same to an optical fiber transmission path 7. The output light from this optical modulator 3 is partly branched by an optical branching device 10 and is converted by a photodetector 11 to an electric signal. The high-frequency signal of the frequency f is extracted by a band-pass filter 12. A mixer 13 subjects this extracted high-frequency signal to coherent detection with the high-frequency signal of the frequency f from a signal source 14 which is delayed by a delay line 15. This detection output is smoothed by a low-pass filter 16 and a control signal is formed.  This control signal is biased by the DC voltage of a DC power source 7 and is superposed on the high-frequency signal from the signal source 14 by a bias T circuit 18.

Title: Servo control circuit for disk device
Inventor: TSUNEKAWA MASAO
IPC: G11B21/10
Filed: 1989-11-17
Abstract: PURPOSE:To prevent the output of erroneous position signal even if an amplitude value of a servo signal becomes abnormally large by allowing a charging current to detect the peak value of the servo signal to be the smaller current control value than the current limiting value in the seaking operation time. CONSTITUTION:In the seak operation time a seaking signal is given to peak detecting means (14-1)-(14-4) and a first current source 24 having a large current limiting value is connected to a transistor 22 by a current switching means 28. Consequently, while the servo signal exceeding the charging voltage of a capacitor 20 the transistor 22 is made to be conductive state and is charged to the voltage corresponding to the peak value of servo signal amplitude. On the other hand, in the on track operation the means 28 is connected to a second current source 26, even if abnormal large amplitude change to the servo signal occurs by a medium flaw and an extrinsic noise, the charging current of peak detecting is suppressed. In such a manner, the influence to the position signal is controlled to the minimum and the output of the erroneous position signal is prevented.
