IPC: C02F3/06
Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To provide a biological filter facilities capable of sufficiently preventing the lowering of filtration performance without lowering biodegradability. SOLUTION: The filter bed 5 of the biological filtration system 10 for executing the removal of the suspended solids in water to be purified and the biodegradation of org. matter by passing the water through the filter bed 5 in a receiving tank 1 consists of an upper layer part 12 for mainly removing the suspended solids and a lower layer part 11 mainly contributing to the biodegradation treatment of the org. matter passing the upper layer part 12. The upper layer particles constituting the upper layer part 12 have the average grain size of 0.2 to 0.3 times the average grain size of the lower layer particles constituting the lower layer part 11 and have a true sp. gr. of <=1.4 times the true sp. gr. thereof.  If, in such a case, backwashing of the filter bed 5 using water and air is executed, the upper layer particles are selectively fluidized and the suspended solids are effectively discharged from the upper layer part 12. On the other hand, the movement of the lower layer particles is sufficiently prevented in the lower layer part 11 and the peeling of the biological membrane sticking to the lower layer particles is sufficiently prevented.

Title: Speaker
Inventor: YOSHIKAWA AKIRA
IPC: H04R7/20
Filed: 1984-06-29
Abstract: PURPOSE:To omit a packing for sealing and lower manufacturing cost by forming the outer periphery of the edge of a speaker unit thick with forming material, and bringing the part into close contact with a part of cabinet. CONSTITUTION:The edge 1 formed in a body by a foaming material is fixed to a frame through wedge paper 2. By forming the part 1b of the outer periphery of the edge 1 to be fixed to a frame 5 thick, the part 1b acts as a packing to seal between a cabinet 4 and the frame 5 and prevents leaking of air. Thus, a packing for sealing so far used becomes unnecessary. Number of parts is reduced and man-hour for assembling is also lessened.

Inventor: SUGIMOTO KAZUHIKO
IPC: H04L12/42
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for switch changes by means of a manual operation, and to improve operability, efficiency and reliability by dividing respective devices constituting a ring into a master device and slave devices and automatically switching an order wire communication line. SOLUTION: An APS processing part 21 receives APS signals from a right side and a left side, takes out only information to self-device ID and transmits information except for the information as it is. An APS monitor part 22 selects APS required for the switching of the order wire communication line(OWL) and outputs switch information. A switch control part 23 outputs a control instruction, based on switch information from the APS monitor 22 and an intra- device alarm processing part 27. Thus, OWL switch part left side and right side 24 and 25 are switched so that with the instruction, OWL is not connected in the device and outside the device. when OWL is required to be switched, the processing part 27 makes the switch control part 23 switch it by an intra- device alarm.

Abstract: PURPOSE:To eliminate the need for the formation of a special mask, and to reduce the area of a memory section by shortening the channel length of an enhancement type MOS transistor. CONSTITUTION:Q9 and Q10 in N channel enhancement type MOS transistors for memories particularly have short channel length. When each terminal 3, 4 of address lines respectively connected to drain electrodes for Q3, Q6 and Q9, Q7 is at a high level and the terminal 5 of an address line connected to drain electrodes for Q5 and Q10 is at a low level, Q3, Q9 and Q6, Q7 are brought to a conductive state, and Q5 is brought to a non-conductive state. Q10 generates a punch-through and is brought to the conductive state at that time because gate potential is at the low level but Q10 has short channel length. Accordingly, an output terminal 6 is brought to VDD potential and an output terminal 7 is brought to low level potential VSS, and the memory informations of Q5 are outputted.

Abstract: PURPOSE:To prevent an increase in control cycle by enabling current sampling only once in a motor control apparatus which converts the detected output of motor current into a digital amount by means of a predetermined decomposition value and switches the gain of a variable gain amplifier on the fore stage of an AD converter. CONSTITUTION:For conversion of the detected output of current of a motor 5 into a digital amount by means of a predetermined resolving power, the gain H1 of a variable gain amplifier 6 on the fore stage of an AD converter is switched according to command value i*. Current of the motor 5 can be sampled only once to stabilize the rotation of the motor 5 by a reduction in control cycle. When a command value is larger than a predetermined value or over a constant time thereafter, the gain of the variable gain amplifier 6 is kept small to prevent commanding to cause a large current to flow despite a real situation that a large current flows.

Filed: 1978-11-08
Abstract: PURPOSE: To fabricate a highly reliable IC at low cost by selectively providing anodic oxidation and epitaxial growth on a p-type single crystal Si subatrate and performing element-to-element separation.  
     CONSTITUTION: An element mounting region 4 is selectively designated through the etching for a p-type single crystal Si 1. An n + -layer 5 is formed on the exposed surface by diffusing Sb and the resulting surface is covered with an oxide film 6. The oxide film 6 after an acid-resistant insulation film 3 and the oxide film 2 have been removed is used to selectively anordize the substrate 1, and then a porous Si- layer is formed on the surface region encompassing the exposed region 4 and a porous Si oxide film 8 is formed by thermal oxidation. After removal of the oxide layer 6, an epitaxial film with desired resistivity and thickness is grown. After simultaneously forming a single crystal Si film 10 and a poly crystal Si film 9, only the film 9 is removed, and then an element D is formed on a single crystal Si film 10 by means of conventional planer method. Like these, with the porous Si oxide film 8 utilized as separation layer, highly reliable ICs can be manufactured at cheaper production cost without resort to diffusion treatment extending over a long period at high temperatures.
