Title: Communication equipment
Inventor: ISHII HIDEJI
IPC: H04N1/32
Filed: 1989-10-11
Abstract: PURPOSE:To reduce the communication time by checking the error state of a first prescribed frame of picture information in place of a TCF signal, and implementing communication of picture information and line check simultaneously. CONSTITUTION:When an error (even one bit) takes place in a received frame in the transmission reception mode by the ECM, the transmission and reception is implemented to send the frame again.

An error bit of a reception frame is detected at a receiver side to execute both the error check processing and the line check processing for picture information. Thus, the redundancy time of the TCF signal in the communication time is used and the line check is also implemented while sending the picture information for the redundant time, then the communication time is reduced.

Title: Optical storage device
Inventor: TANAHASHI YUTAKA
IPC: G11B20/18
Filed: 1987-10-20
Abstract: PURPOSE:To secure a level margin with respect to the deterioration of a signal amplitude and noise erroneous detection and to improve a reproduced erroneous margin by using two large and small thresholds with respect to a level detection threshold which is used at the time of normal reproduction, and checking the regenerated analogue signal level at the time of verification reproduction. CONSTITUTION:A level comparator 5 level-compares the analogue signal (a) with a second threshold VH which is larger then first threshold voltages VL and VL, and it goes to a logic that a first level signal (e) being a compared result shows '1' when the regenerated analogue signal (a) is more than VL, and a second level signal (d) shows '1' when the regenerated analogue signal (a) is more than VH. The first level signal (e) and the second level signal (d) are supplied to a non-coincident detection circuit 6 and a D-shaped flip flop circuit 7. When there is non-coincident detection at the time of verification, storage information is processed as an error.

Abstract: PURPOSE:To prevent speed change shocks and improve riding comfort by increasing the transmission ratio of an automatic transmission gear when target driving force goes beyond the prescribed proportion of a maximum driving force which the automatic transmission gear can output with a working transmission ratio at actual vehicle speed. CONSTITUTION:An output adjusting means M7 for the throttle valve M6 of an internal combustion engine M2 is controlled by a means M10 for constant speed control of a vehicle M1.

Abstract: PROBLEM TO BE SOLVED: To shorten a time to such extent that a starting pump and an already operating pump are operated synchronously by reducing an increasing rate of a frequency of an inverter in the starting pump when rotating speed of a new starting pump attains rotating speed which is set according to rotating speed of the already operated pump, when a pump is additionally started. SOLUTION: When a pump device for water supply and sewerage systems provided with a plurality of pumps 1 is operated, a pump discharge rate is measured at all times by a flow rate transmitter 8, and total flow rates are calculated from its measured result by a controller 12. Start and stop periods of the pump are judged on the basis of the total flow rate of the pump. In the case where a new pump is started in addition to an already operated pump, in a region where rotating speed N2 of the starting pump is smaller than rotating speed αN1 set according to rotating speed N1 of the already operated pump, a frequency of an inverter 14 is increased with a comparatively large increase pace, and rotating speed N2 of the starting pump is increased.  In the case where the rotating speed N2 of the starting pump exceeds the rotating speed αN1, the increase pace of the frequency of the inverter 14 in the starting pump is reduced.
