IPC: B01D29/62
Filed: 1990-01-29
Abstract: PURPOSE:To shorten the washing cycle by providing plural filter tubes provided with filter medium on its peripheral surface and carrying out filtration through the filter medium. CONSTITUTION:When backwashing process is to be carried out, a revolving cylinder 24 is driven to rotate a vertical moving rod 14 to intercept the inner part of the filter tube 10 from an auxiliary tank 3. Then, a vertical moving cylinder 27 is put in operation to raise the vertical moving rod 14 so that a lower bottom plate 13 is raised against the potential force of a coil 11 unit the length of the filter tube becomes half. The filtered matter on the surface of the filter medium 12 is compressed and broken, and the clean liquid in the inner part of the filter tube 10 is spouted from the surface of the filter medium 12 by the volume contraction of the inner part. The broken filtered matter is allowed to flow and exfoliated to the side of main tank by the washing liquid. After the backwashing treatment, an opening and closing valve 32 is opened to discharge the liquid to be treated mixed with the exfoliated filtered matter from a drain opening 5. By this method, the consumption of clean liquid is reduced.

Title: Magnetic bubble memory element
Inventor: SAITO KATSUTOSHI
IPC: G11C11/14
Filed: 1987-02-02
Abstract: PURPOSE:To obtain a practically sufficient transfer characteristic even with a magnetic bubble diameter decreased by forming a magnetic bubble detector pattern of a magnetic bubble detector through the provision of a inflection point. CONSTITUTION:In a detector pattern DP constituting a magnetic bubble detector, the magnetic bubble detection side pattern DPS is formed to have a curvature by inflection points DPS1, DPS2. Through the constitution above, since a minute projected pattern having the inflection points DPS1, DPS2 as apexes is formed through the forming of the pattern DPS with a curvature, a magnetic field is formed sequentially to the projecting pattern in the stage of a rotating magnetic field from nearly 0 deg. to nearly 85 deg.. The magnetic bubble B1 of the middle part of the pattern DP is transferred stepwise in the order of magnetic bubbles B11, B12 and B2 accordingly and the occurrence of mis-transfer is avoided. Moreover, the effective element length of the pattern DPS is prolonged and the resistance is increased by it, then a large detection output is obtained.

Title: Coordinate input device and coordinate input display device
Inventor: BABA TAKASHI
IPC: G06F3/037
Filed: 1996-02-07
Abstract: PROBLEM TO BE SOLVED: To display free contents without placing any load on a host computer by outputting the area number corresponding to a previously set area when the area is pointed. SOLUTION: A coordinate input value detection part 109 of a digitizer control part 107 inputs a voltage value according to a previously set sampling rate. Then the detection part 109 converts this voltage value into the coordinate value (coordinate data) corresponding to an LCD 102. When the coordinate data are inputted from the detection part 109 to a coordinate value area decision processing part 110, a decision process is performed by referring to an area data storage part 108. When the coordinate data correspond to a coordinate value input area, a decision processing part 110 outputs the coordinate data to the host computer 110 through a communication part 112. Consequently, the position of a function area can freely be set even when the display screen is switched on the coordinate input device which reduces the load of the CPU process on the host computer side.

Title: Air conditioner for vehicle
Inventor: HONDA YUJI
IPC: B60H1/00
Filed: 1992-02-06
Abstract: PURPOSE:To protect a user against unpleasant feeling for a sound effect due to an air increase or decrease caused by oscillation mode. CONSTITUTION:An automotive air conditioner 1 is equipped with a duct 2 forming an air passage for an air flow into a cabin, and a fan 4 for feeding the air into the cabin via the duct 2. A control device 26 executes oscillation mode by increasing or decreasing a flow of electric current to the fan 4. Also, the control device 26 narrows the range of oscillation in a service environment condition where a travel speed is low, while expanding the range as the travel speed increases. As a result, when the travel speed and travel sound are low, the oscillation range becomes narrow, and unpleasant feeling due to a noise can be restrained. Thus, unpleasant feeling due to an oscillation sound can be eliminated, even if the range is expanded at the time of a high travel speed and sound, and only comfortable oscillation feeling is given to a user.
