Abstract: PROBLEM TO BE SOLVED: To provide a device in which a heavy metal is removed from a material to be treated such as sludge. SOLUTION: A powdery chelating agent sent from a hopper 1 of a chelate powder and water are agitated in a chelate tank 2. When dehydrated sludge sent from a sludge receiving hopper 5 is mixed for 30 minutes with a chelate aqueous solution sent from the chelate tank 2 in a mixing tank 4, a chelate compound incorporated with heavy metallic ions contained in sludge is produced. The mixture sent from the mixing tank 4 and oil are agitated in an agitation regulation tank 7 and thereafter the mixture in the agitation regulation tank 7 is led to an oil temperature decomposition type drier 8 and heated at about 110 deg.C in a decompression state not higher than the atmospheric pressure. Water contained in the mixture is evaporated and substituted for oil. A heavy metal contained in sludge and the chelate compound are eluted in oil.  Dehydrated sludge discharged from the oil temperature decompression type drier 8 is deoiled by a centrifugal separator 9 and becomes organic manure. The separated oil is incinerated by an incinerator 11 and recovered as ashes.

Abstract: PURPOSE:To change accurately the width of a slab during continuous casting by integrating the pulse signals transmitted from command pulse transmitters with counters, comparing the same with the target set pulse values which are beforehand set and controlling the command pulse transmitters. CONSTITUTION:Changing of the width of a slab during continuous casting by moving the short side pieces 2a of a casting mold via stepping cylinders 3a, 3a' is accomplished by applying the command signal from a control device 6 for commanding calculation, via counters 50, 50', to command pulse transmitters 4, 4,' and applying the transmission pulse signals from the transmitters 4, 4' to stepping cylinders 3a, 3a' in accordance with the command signal to move the piece 2a.

Title: Communication control system
Inventor: OGAWA TOSHIO
IPC: H04L29/08
Filed: 1982-10-20
Abstract: PURPOSE:To prevent the double processing owing to a fault of a transmission part of a slave station, by testing the function of a transmitter of acknowledge signal after reception of a command signal. CONSTITUTION:A command signal transmitted onto a transmission line L from a master M is stored temporarily in a buffer memory 13 via a receiving circuit 11. A logic control part 30 checks the stored contents of the buffer 13 to perform an error check or an address check. Then a confirmation signal of a bit pattern which is not recognized as a significant signal frame is transmitted onto the line L. This confirmation signal is detected by a carrier detecting circuit 12, and the result of this detection is sent to a logic control part 30. If the absence of carrier is decided, a fault is decided with a transmitting circuit 22 to avoid performing the processing of the received command signal. Then an acknowledge signal is transmitted after the command signal is processed.

IPC: G02B6/10
Filed: 1994-08-05
Abstract: PURPOSE:To obtain an optical fiber having an end reflection mirror improved in durability by subjecting the end at the core end of an optical fiber together with an adapter to end face polishing and forming a light reflection film at the polished end face. CONSTITUTION:After a projective film 2 the axial direction of the optical fiber core 1 is removed, the optical fiber core 1 is inserted into the adapter 3 of the bore slightly larger than the bore of the optical fiber core 1 and is joined to the adapter 3. The end face is thereafter polished together with the adapter 3 and the reflection mirror deposited with a reflection film 5 by evaporation is stuck by adhesion to the end face at the rear. As a result, the vapor deposition on the bulk material having the larger bore is made possible and since the coating at a high temp. is possible, the durability of the reflection film 5 is greatly improved at the time of forming the reflection film 5. The need for using an adhesive on an optical path is eliminated by using the adapter 3 and adhering the adapter 3 to the reflection film 5 and, therefore, the optical fiber is hardly affected by the deterioration of the adhesive with lapse of time.

Title: Shared buffer system
Inventor: KANAZAWA NOBUHARU
IPC: G06F13/38
Filed: 1990-07-16
Abstract: PURPOSE:To reduce the hardware quantity by carrying out the transfer of data after setting the contents of each pointer related to other processing when another transfer of data is carried out in a data transfer state. CONSTITUTION:The transfer data are recorded to a buffer 1 and the data store state of the buffer 1 is displayed on a queue buffer 2. When another data transfer is carried out in a data transfer state, the states of a queue input pointer 3, a queue output pointer 4, a transmission signal input pointer 5, and a transmission signal read pointer 6 are saved into each saving memory. Then the contents of pointers 3 - 6 are set for another data transfer, and this transfer of data is carried out. When this processing is over, the saved contents of each pointer are restored and the precedent processing is carried on successively. Therefore both command and answer transmission buffers are not needed when another command is received and an answer is transmitted in a state where the answer is waited to the command. Thus the number of buffers is decreased and a hardware scale is also reduced.
