Abstract: PURPOSE:To increase the processing capability by putting and mixing a solidifying agent into mud, pressurizing and dehydrating the solidified mud, putting a coagulant after dehydration, generating bubbles, recovering fine particles on the water surface, and dehydrating. CONSTITUTION:When mud H is put in a vibrating sieve 10, the flowing mud is fed into a mixing device 40, it is mixed with a solidifying agent fed from a solidifying agent adding device 50, then it is conveyed to a temporary deposition site 80 by a screw conveyor 30. The solidified mud is pressurized and dehydrated by a pressure dehydrator 60, and a dehydrated cake is solidified by a solidification processor 70 and conveyed to the deposition site 80. A coagulant is put into the dehydrated liquid in a coagulation/precipitation tank 110 from a coagulant adding device 120 to form organic matters into blocks, and they are floated on the water surface by an extremely fine bubble generator 130. The blocks are dehydrated by a pressure dehydrator 140 and the solidification processor 70, and fine particles are separated and recovered. The sediment in the precipitation tank 110 is conveyed to the mixing device 40 by a mud feed pump 150.

IPC: G21F9/02
Filed: 1998-09-16
Abstract: PROBLEM TO BE SOLVED: To continuously carry out a product and waste material from an isotope separating device without cancelling vacuum in a vacuum vessel. SOLUTION: A differential exhaust system 20 is communicated with the bottom of a vacuum vessel (a) through a gate valve 10. In the differential exhaust system 20, plural sub-vacuum chambers 21 vertically forming a line, are communicated with each other and evacuated so that the lower the position of the sub-vacuum chamber 21 is, the more the degree of vacuum approaches atmospheric pressure. The product and waste material are introduced by a ribbed shooter part 40 and a water cooling shooter 41 to fall down and goes into the differential exhaust system 20 through the gate valve 10. The product and waste material move downward step by step through the sub-vacuum chambers 21 in the differential exhaust system 20 and falls down into a recovering vessel 50 from the lower end of the differential exhaust system 20.  Even when the product and waste material move downward in the differential exhaust system 20, the degree of vacuum in each sub-vacuum chamber 21 is secured and the degree of vacuum in the vacuum vessel (a) is not lowered.

Abstract: PROBLEM TO BE SOLVED: To smoothly guide an image-formed recording medium in the discharge direction without being attracted to a discharge guide by providing the discharge guide for making wind flow in the carrying direction on this surface for guiding an image part in the carrying direction. SOLUTION: Air blown out of respective air blowing exhaust ports 40 flows in the arrow C direction on a surface 32 of a discharge guide plate 30. A recording paper carrying directional downstream side part 24b of a platen 24 is positioned in a slightly upper part of the respective air blowing exhaust ports 40. Thus, when blowing out wind from the air blowing exhaust ports 40 before a discharge part 22a of roll paper 22 reaches the air blowing exhaust ports 40, an air layer is formed between the discharge part 22a and the surface 32 of the discharge guide plate 30.  Thus, the discharge part 22a is guided in the arrow C direction without contacting with the surface 32, so that static electricity caused by friction of the discharge part 22a and the surface 32 of the discharge guide plate 30 is not generated, and the discharge part 22a is not electrostatically attracted to the surface 32 of the discharge guide plate 30.

Title: Oilless type variable displacement compressor
Inventor: MORI HIDETOMO
IPC: F04C28/02
Filed: 1999-09-16
Abstract: PROBLEM TO BE SOLVED: To provide a speed control at approximately a constant pressure irrespective of the amount gas in service by providing a blow-off valve having a plurality of ON-OFF control valves installed thereon in parallel with each other, reducing the amount of each blow air more than a specified amount of gas, and increasing the sum of the amounts of blow air from all ON-OFF control valves over a specified amount of gas. SOLUTION: A blow-off valve 8 is formed of a plurality of ON-OFF control valves arranged in parallel with each other blowing compressed air when the amount of air in service Qc is smaller than a specified amount of air qc0. The amount of blow air from solenoid valves (a) and (b) is set at approximately 1/3 of qc0, and that from a solenoid valve (c) is set at a value slightly larger than 1/3 of qc0. Thus, when the solenoid valves (a) to (c) are opened, the total of qc0 can be blown off and, even if Qc becomes zero, a compressor 2 can perform a constant pressure control continuously, and the amount of delivery air Qs from the compressor 2 becomes slightly larger than qc0. Thus, because the amount of air Qs delivered from the compressor 2 is larger than the specified amount of air qc0, the compressor 2 can always perform the constant pressure control.

Title: Display method for relationship between hyper-texts
Inventor: SUZUKI TOSHIMITSU
IPC: G06F3/048
Filed: 1988-10-18
Abstract: PURPOSE:To obviously display the relationship among the hyper-texts by displaying the links bearing arrows among those texts which are shown in a multi-window form. CONSTITUTION:When a window 100 is opened on the screen of a CRT display device 40, a CPU 20 detects a window display command and decides each link start point window display coordinates. Then the coordinates to be displayed for a link window is decided and a window 102 to be linked is displayed. Then an arrow is drawn between the link start and end point window display coordinates. The drawn coordinate data is registered into a main memory 22. Such a process is applied to the window where a text retrieved out of the items designated in each window displayed on a screen is displayed. Thus the links 200-206 are drawn. As a result, the relationship is obviously shown among hyper-texts.

Filed: 1986-11-06
Abstract: PURPOSE:To prevent a toner image from scattering and to fix an image where the edge of the solid part is sharp by providing a form destaticizing means which destaticizes a form guided to between rolls. CONSTITUTION:The form destaticizing means is provided which destaticizes the form guided to between the rolls.

Title: Multiplex transmitter
Inventor: OBA KIYOTSUGU
IPC: H04Q9/00
Filed: 1993-10-20
Abstract: PURPOSE:To reduce power consumption by transmitting data to a first multiplex unit only when any switch is turned on and stopping all the motors when any data are not received from a second multiplex unit longer than fixed time. CONSTITUTION:When all the switches A-C are turned off, a multiplex unit TX' on the transmission side judges whether the count value of a transmission counter is '0' or not. Namely, in this case, it is judged whether the first data transmission processing from the OFF of all the switches A-C is performed or not. When the count value of the transmission counter is '0' in this case, this judged result is YES. After '1' is set to the count value of the transmission counter, the switch state is encoded and data are transmitted. Thus, a multiplex unit RX' on the reception side stops all the motors MA-MC. Therefore, when all the switches A-C are turned off, data corresponding to this state are transmitted just once so as to stop all the motors MA-MC.
