Title: Blocking prevention device of waste separator
Inventor: NOKITA EIJI
IPC: B65G53/66
Filed: 1991-11-13
Abstract: PURPOSE:To prevent the lower part of a separator due to dust by widening a discharge pipe communicating with a separator and a compactor part and thereby making the volume larger enough to retain and store the quantity of dust transported by a single return trip of the compactor part, in comparison with the compacted dust volume. CONSTITUTION:An accumulation part 12 is formed so that it has a larger accommodation capacity that the volume of dust transported by a single return trip of a compactor part 21. In addition, the accumulation part 12 is provided between a separator 1 and the compactor part 21, so that the separated dust can be discharged to the compactor part 21 with a sufficient extra accommodation capacity, if the volume of transported dust increases. If a low level gauge L1 is turned ON, the compactor part 21 continuously shuttles back and forth to compact dust and transport the compacted dust to a container part 22. In this case, however, the accumulation part 12 still retains an extra accommodation capacity, so that a high-level gauge LH does not become activated during the advance action of the compactor part 21. Thus the transport of dust is not longer suspended and subsequently, the lower part of the separator 1 does not become blocked.

Title: Freon recovery apparatus
Inventor: TOMARU KEIICHI
IPC: F25B45/00
Filed: 1988-11-26
Abstract: PURPOSE:To enable the recovered 'Freon(R)' to be reused and to prevent a recovery container from becoming high pressure by furnishing a first valve that opens and closes a path leading form a recovery section to a cooling section in a primary circuit, a second valve on a path that connects the inlet of the cooling section and a first inlet of a recovery container, and a third value on a path that connects the outlet of the cooling section and a second inlet of the recovery container. CONSTITUTION:In recovering 'Freon(R)', a first valve EV1 is opened first, and second and third valves EV2 and EV3 are closed. Thereby, a secondary circuit is put into operation under such a state that a recovered section 11 and a cooling section 14 are connected, and the Freon is cooled and liquefied by the cooling section. When the pressure in the cooling section drops due to the liquefaction of the Freon, the Freon in the recovered section is evaporated and sucked into the cooling section where the Freon is again cooled, condensed, liquefied and stored in the cooling section. After the liquefied 'Freon(R)' is accumulated in the cooling section, the first valve is closed, and the second and third valves are opened. Thereby, the recovered section is isolated, and the pressure in the cooling section and a recovery container 15 is equalized. At this state, the 'Freon(R)' accumulated in the cooling section flows down by gravity into the recovery container 15 located under the cooling section.

IPC: H04N1/23
Filed: 1986-12-15
Abstract: PURPOSE:To eliminate noises and prevent moire fringe, ununiformity in hue or the like from being generated, by varying the recording timing by a predetermined amount for each of primary colors, and ensuring that the sum total of variations of a predetermined number of successive recording picture elements for arbitrary recording picture elements is less than a predetermined value, at the time of density gradation recording. CONSTITUTION:A data latch part 11a in a gradation data converting part 11 reads gradation data on each picture element in response to a line start signal (generated with a predetermined timing), and latches the gradation data. The line start signal is sent also to a variable delaying part 13c, whereby it is converted into a recording timing strobe signal for driving a head for each recording picture element, according to an arbitrary timing generated by a random number generating part 13a. A pulse generator 12a in an imagerecording part 12 generates pulses with a duration optimum for driving heat generating elements 12c on the basis of output from a driving pulse duration memory (ROM) 11b and an arbitrary recording timing outputted from the delaying part 13c. Noises in images to be recorded are eliminated by an effect similar to the effect of screen angle setting, and moire fringe, ununiformity in hue or the like can be securely prevented from being generated.
