Title: Consecutive transmission frame reception system in facsimile equipment
Inventor: SAKAYAMA TAKASHI
IPC: H04N1/32
Filed: 1990-06-08
Abstract: PURPOSE:To reduce the communication time by discriminating it to be the reception of expected all frames when a binary code command of a first frame in a consecutive transmission frame is normally received. CONSTITUTION:A control CPU 6 starts a frame reception section 2 to start frame reception. A carrier in a signal is detected by a carrier detection section 5 and a flag pattern detection section 4 detects a flag pattern F included in the reception frame, then the synchronization is taken with the flag pattern and every time a normal frame is received, it is stored in a reception frame buffer 3. When the detection section 5 of the reception section 2 detects carrier- off, that is, the data end of the consecutive transmission frame comprising an NSF signal and a DIS signal is informed to the CPU 6. The CPU 6 awaits the end of reception to check a buffer 3 and when the NSF command is not received and the frame is the first frame, the buffer 3 is cleared to start the reception section 2 again to retry the frame reception.

IPC: D06F33/02
Filed: 1990-06-08
Abstract: PURPOSE:To hasten the time of cloth quantity determination for laundry stuff in a washing tank by providing a cloth quantity detection step where, prior to water feed to the washing tank, a stirring blade is operated at a rotational speed lower than the normal rotational speed. CONSTITUTION:In a main control means 11, a signal of a rotational speed detector 6 is inputted via a rotational speed detection control unit 16 and also a signal of a water level detector 8 is inputted via a water level detection control unit 8. In this case, laundry stuff is thrown into a washing tank 2 and a stirring blade 3 is rotated at a low speed, so that the laundry stuff turns round together with the stirring blade 3. Therefore, a change in the rotational speed of the stirring blade 3 due to frictional resistance between the laundry stuff and the washing tank 2 is detected. From the extent of this change, the quantity of cloth is thus immediately determined. Consequently, the inconvenience that a person must stand at the side of a washing machine for one or two minutes after start of the operation can be eliminated.

Abstract: PURPOSE:To keep off any double-feed, feed paper slip and damage to a sheet of recording paper with less load by installing a reverse roller which presses and separates a second feed roller from the underside and handles the second sheet and after of the recording paper. CONSTITUTION:A kick-down lever 22 generates such force as winding the second sheet of recording paper 12 upside down on a reverse roller 16, producing a strong reverse feeding force there. Accordingly, even if energizing force of an energizing means 21 is set so weakly, any double feed is preventable. In addition, if the energizing force is set feebly, conveying load of the first sheet of the paper 12 is reduced, thereby making a feeding paper slip preventable too. Moreover, since a contact area between the kick-down lever 22 and the paper 12 is increased, pressure per unit area is decreased, through which any damage to the paper is made hard to be incurred.
