Abstract: PROBLEM TO BE SOLVED: To improve the durability of an attracting roller and a carrying belt and to realize normal operation by electrostatically attracting toner stuck to a conductive member to a transfer material carrier and removing the attracted toner by a cleaning device. SOLUTION: A transfer sheet 105f is electrically initialized by an inside discharging device 105d and an outside discharging device 105e. At such a time, the attracting roller 105g and an attracting and electrifying brush 105c abut on the transfer sheet 105f, and an attracting current (charge) is injected from the brush 105c. Since the roller 105g is electrically grounded, a current (charge) in a reverse direction (reverse polarity) to the current (charge) injected by the brush 105c is induced. As a result, soiling such as toner stuck to the roller 105g is attracted to the transfer sheet 105f. Such problems as the durability of a scraper is insufficent, the image is adversely influenced by vibration caused by the abutting of the scraper, and the normal operation of a transfer drum 105a is disturbed are solved.

Title: Information recording and reproducing device
Inventor: TAKESHITA KANAE
IPC: G11B20/14
Filed: 1989-12-20
Abstract: PURPOSE:To correctly regenerate a synchronizing pattern and to stably reproducing a data by providing a means for detecting a regenerative signal of the synchronizing pattern deviated from a prescribed allowable phase range and deciding whether the recording state of the synchronizing pattern is good or not from a comparison result between a counted result of this detecting signal and an allowable value. CONSTITUTION:When a pulse signal of the synchronizing pattern is deviated from the prescribed phase range, the signal is outputted to a counter 19 by a delay element 15, an inverter 16, a flip-flop (FF) circuit 17 and an Ff circuit 18. On the other hand, a signal for showing an area of the synchronizing pattern is outputted to the counter 19 by a synchronizing pattern area detecting circuit 12 based on an SM signal S2 outputted from a sector mark detecting circuit 11. Then, a counted value of the counter 19 is outputted to a comparator 20. The counted value of the counter 19 is compared by the comparator 20 with a preset allowable value, and if it is within the allowable value, the recording state of the synchronizing pattern is regarded as good, and a signal for showing this effect is outputted to a control part. By this method, the synchronizing pattern can stably and correctly be detected, and the data can always accurately be reproduced.

Title: Wireless remote control of electric appliance
Inventor: MURAMATSU TAKESHI
IPC: H04Q9/00
Filed: 1990-11-27
Abstract: PURPOSE:To reduce electric power consumption by varying the on-off time of the power source to be supplied to a signal receiving section according to the contents of received monitor information and increasing the ratio of the off time when a communication frequency is low. CONSTITUTION:The power source 17 of the signal receiving section 8 of the remote control 1 is turned on and off by a power source controller 9. The power source is impressed at the period of the on time T3and the off time T1 during the function stop of the one hot water feeding machine body of the monitor information. The signal receiving section 8 decides the presence or absence of the signal reception within the time T3. The control section 9 changes the off time T1 to T2 (<T1) when the monitor information of the hot water feeding function changes to operation upon receipt of a packet A. The T2 changes to the T1 upon receipt of a packet B. The packet after changing the monitor information changes the preamble part slightly longer than the power source off time in the signal transmitting and receiving section 6 of the hot water feeder body 5. The hot water feeding stop time of the signal reception time is shortened only under the operation or when there is an instruction for a specific function by this constitution and, therefore, the electric power consumption of the signal receiving section is reduced without allowing the delay in communication by intermittent signal reception to pose any probe in operation.

Title: Asynchronous signal transmission/reception circuit
Inventor: KABAYA EIICHI
IPC: H04L29/08
Filed: 1989-12-18
Abstract: PURPOSE:To prevent a data transmission/reception error cause by the contention of both latch timings at a transmission side and a reception side by masking the latch timing at the transmission side in the vicinity of the latch timing of the reception side. CONSTITUTION:A reception side pulse generating section 2 generates a latch pulse 2 and sends it to a control section 4, generates a masking pulse designating the inhibiting period of a preset length over before and after the appearance period of the latch pulse 2 and sends it to a comparison section 3. The comparison section 3 sends a latch pulse 3 masking the latch pulse 1 at the transmission side designated by the masking pulse to the control section 4. The control section 4 latches an input data synchronously with the frame pulse 1 given from the transmission side by using the latch pulse 3 and reads the data to obtain an output data by latching the read data by using the latch pulse 2. Thus, the malfunction due to the contention of the latch pulse is prevented.
