Filed: 1989-08-23
Abstract: PURPOSE:To accurately read out and write information by contacting the brush of a cleaning part with the recording face of an optical disk and brushing the recording face in accordance with the rotation of a disk to remove dust. CONSTITUTION:Apertures are opened on the upper and lower faces of a card- like case 12 and the case 12 is loaded to an optical disk device so as to be ejected. At the time of using an optical disk cartridge 10, the case 12 is inserted into the optical disk device, a shutter 22 is driven so as to expose the apertures of the bottom part and the cover part of the case 12 and the hole of the optical disk 24 is connected to a turn table. At the time of starting the rotation of the turn table, the recording face of the optical disk is rotated in the contacted state with the brush 36 of the cleaning part 28 and an air flow occurs.

IPC: G06F11/22
Filed: 1986-09-16
Abstract: PURPOSE:To display a substrate which has a fault part by transmitting a signal from a master substrate to a check substrate when abnormality occurs in the transmission of signals. CONSTITUTION:When a fault occurs in a *X part in a slave substrate 5, a parity check circuit 51 detects the abnormality in the signal transmission, which is received, and transmits an ERR signal to a signal line 1c. A CPU substrate 2 receives the ERR signal and diagnostic control circuit 26 makes a CPU function circuit 23 start so as to begin to transmit the signal from the CPU substrate 2 to the check substrate 3. In this case the check substrate 3 transmits an ACK signal concerning normal completion to a signal line 1b. When the CPU function circuit 23 receives the ACK signal, it informs that the signal transmission is normally completed to the diagnostic control circuit 26. The diagnostic control circuit 26 decides that the fault occurs in the slave substrate 5 and indicates the number of the substrate on an indicator 4.

Title: Low-noise amplifier, mixer and frequency synthesizer circuitfor radio frequency system
Inventor: BEZATSUDO RAZABUI
IPC: H03K3/354
Filed: 1996-08-20
Abstract: PROBLEM TO BE SOLVED: To integrate a low noise amplifier, mixer and frequency synthesizer circuit with which a phase noise or a bond higher-harmonic wave is low. SOLUTION: A bias current is supplied from a power source 23 to an LNA 12. A frequency synthesizer 20 is directly connected to the LNA 12 and in order to supply a bias current required for an oscillator existent inside the frequency synthesizer 20, the non-used bias current in the LNA 12 is utilized.

The LNA 12 is connected through an inductor to the frequency synthesizer 20. That inductor suppresses the band higher-harmonic wave by generating resonance at nodes, which are connected to mixers 16 and 19, between the LNA 12 and the frequency synthesizer 20.

Title: Communication fault processing system
Inventor: MATSUSHITA SHINJI
IPC: H04L69/40
Filed: 1990-08-20
Abstract: PURPOSE:To minimize the interference to the communication between a master device and each normal slave device by successively performing polling from the master device to each slave device and, when the number of continuously occurring times of such a state that the same slave device does not answer within prescribed time reach a prefixed value, discriminating the slave device as abnormal. CONSTITUTION:A polling means 100 successively executes poling to each slave device 2 without making the polling continuously to the same device 2 irrespective of the response from each device 2 to a master device 1 within prescribed time. Each counting means 200 counts the number of continuously occurring times of such a state that each device 2 does not answer against the polling from the master device 1 within prescribed time. When the count value of one means 200 reaches a prefixed value, an abnormality discriminating means 300 discriminates that an abnormal state occurs in the slave device 2 corresponding to the means 200. Therefore, even when such a state that one slave device does not return an answer telegraphic message occurs, a delay in polling period to the normal slave devices can be pervented, since the polling can be retried while the normal polling period is maintained.
