Title: Facsimile communication method
Inventor: SAKAGUCHI IKUNORI
IPC: H04L13/08
Filed: 1985-03-08
Abstract: PURPOSE:To perform communication between memories with no mistake by informing the vacant capacity of a receiver to a transmitter by the receiver itself prior to reception of picture data and transferring the picture data to the memory of the receiver by the transmitter only when the picture data can be stored in said vacant memory capacity. CONSTITUTION:When a call is set up, well-known handshake is carried out between a transmitter and a receiver. Based on this handshake, it is decided by a non-standard device signal NSF sent from the receiver whether or not the receiver has picture data equal to that of the transmitter. At the same time, the number of pages of the memory is decided by a CPU 1 set at the transmitter side. In other words, the receiver puts the capacity of its memory 4 into the signal NSF in the form of the information on the page number (P2). Then the receiver adds the page number (P2) of the memory 4 into the signal NSF to be sent to the transmitter through the handshake carried out after a call is set up.

IPC: C02F1/24
Filed: 1980-04-10
Abstract: PURPOSE: To continuously take out a highly concentrated sludge under a stable condition, by detecting the downside surface of a floating sludge zone with a boundary gauge, changing the head of a sparated water so as to fluctuate the whole of the floating sludge zone, and controlling the amount of the floating sludge to be scraped out.  
     CONSTITUTION: When a sludge is compressed, floating and concentrated, a floating sludge zone 2 is generated at the upper part in a floatation concentration tank 1. If the downside surface 2a of the zone 2 is detected by a lower boundary gauge 3, a controller 12 lifts a separated water-introducing pipe 8 upwards to raise the head of the separated water and to lift the whole of the floating sludge zone 2. Consequently, the amount of the floating sludge to be scraped out by a scraper 14 is increased. If the downside surface 2a of the zone 2 is detected by an upper boundary gauge 4, the controller 12 lowers the separated water-introducing pipe 8 to descend the head of the separated water and to lower the whole of the floating sludge zone 2. Consequently, the amount of the floating sludge to be scraped out is decreased.

Abstract: PURPOSE:To provide a press treating device for empty cans which has a simplified construction and is improved in a screening function by providing a mechanism for selecting a material to be pressed on a chute side and turning the screening mechanism with a pressing lever which is provided to a pressing plate. CONSTITUTION:An empty can in a press section 17 is pressed by a pressing plate 13, and a treated material K' falls onto a chute 19. If the material K' is a nonmagnetic material, the material glides on the chute 19 and is released into one container. If the material K' is a magnetic material, the material is stopped temporarily on the chute 19 by the attraction effect of a permanent magnet 29. When the next pressing operation is started, the chute 10 is turned counterclockwise by the advancement of the plate 13. A holding plate 28 parts from the chute 19 upon attaining a horizontal position and a regulating pin 31 contacts with a stopper 32, thus resetting the plate to the home position. The chute 19 turns further to incline to the receiving plate 11 side, thereby discharging the material K' into the other container.

Abstract: PURPOSE:To suppress the overheating of the magnetic material such as a transformer tank and the like even when a harmonic current generated in a converter flows into the transformer by a method wherein the communication of each converter is conducted with a specific phase difference. CONSTITUTION:An input winding is divided into two groups of winding (H1 and H2 windings), they are connected to a power source after they have been papallel-connected, and the L1 and L2 windings, which have strong magnetic coupling force against the H1 winding, and L3 and L4 winding, which have magnetic coupling force against the H2 winding, are arranged. Then, after converters C1 to C4 have been connected to the above-mentioned four windings, they are operated with the carrier phases as follows: C1 with carrier phase 0 deg., C2 with theta, C3 with 90 deg. and C4 with 90 deg.+theta deg.. The operation is limited within the range of 0 deg.<=theta deg.<=45 deg.. Accordingly, in the operation in carrier phase, a harmonic current of almost the same phase is made to flow on the L1 and L2, and a harmonic current of almost the same phase is made to flow on the L3 and L4, but an antiphase current is made to flow on the H1 and H2. As a result, the harmonic magnetic flux penetrating the transformer tank is lessened, and as a result, the overheating of the tank can be removed..
