Title: Apparatus for filthy water disposal
Inventor: MURAYAMA JIYOUJI
IPC: C02F3/06
Filed: 1982-08-05
Abstract: PURPOSE:To perform the stable denitrification of filthy water, by forming a horizontal section containing the layer of obstacles constituting a liquid-descending part and an empty liquid-ascending part in the titled apparatus, and injecting air into the liquid-ascending part to form the circulating current of the liquid. CONSTITUTION:Raw filthy water flows through a pipe 7 for the inflow of filthy water into an aeration tank 1 having a proper horizontal section. Air is sprayed through a porous injection part 2a provided at a proper position below aliquid- ascending part 1a to raise the filthy water by the action of air lift and to dissolve air in the filthy water. The air having risen and reached the liquid surface 1b flows together with sludge corresponding to filthy water flowing in through the pipe 7 for the inflow of filthy water and returned sludge from an outflow pipe 8 to a precipitation tank 4. Most of the filthy water having risen through the liquid-ascending part 1a falls downwards through a stationary bed 3 and follows a jigzag course since its passageway is curved by fillers. Hence, the agitatively mixing is well performed to execute the aeration with the dissolved oxygen.

Title: Drive circuit of photocoupler
Inventor: MORI FUMIHIKO
IPC: H01L31/12
Filed: 1987-05-29
Abstract: PURPOSE:To improve frequency characteristic and to remove the distortion of a signal by connecting the anode of a light emitting diode to the common connection point of a plurality of resistors connected in series between a reference power supply and a ground and a cathode to the output of a logic circuit. CONSTITUTION:Resistors R1 and R2 are connected in series, for example, between a reference power supply and a ground, and the common connection point of the resistors R1, R2 is connected to the anode of a light emitting diode LED. Since the anode potential of the diode LED drops by connecting the resistor R2, the falling of a voltage at both terminals is accelerated when the diode LED is turned OFF. Thus, it can prevent the H level period of an output signal from shortening due to the delay of the rising of the output of a photocoupler PC. Further, since the input current of the photocoupler PC is reduced, the delay at the time of rising the signal is reduced, and the delay at the time of falling the signal is increased. Thus, the H level period of the output signal can be extended. Accordingly, the duty ratio of the input to the output can be maintained the same.

Abstract: PURPOSE:To prevent environmental contamination and enable dredging at low cost, by rotating a cylindrical rotary body having a plurality of permeation holes over its circumferential surface, about its vertical axis, the rotary body partitioning a hedro (sludge) layer into internal and external parts, and, during this rotation, sucking in and discharging the hedro mass while maintaining a pressure difference between the interior and the exterior. CONSTITUTION:Initially, a rotary body 2 suitably formed, over its entire circumferential surface, with slit-like permeation holes 3 is mounted to an auxiliary rotary body 5 to thereby assemble a dredging apparatus which is so constructed as to rotate about its vertical axis within a first framewark 10, by means of a chain 12, in response to the starting of a submerged motor 13, via a sprocket 14. Next, this apparatus is set at a predetermined position, and the submerged motor 13, submerged pump 20, etc., are operated to suck in a hedro and water from a suction port 23 which in turn are delivered under pressure to the outside through a discharge port 24 and a pipe line 54. And a specified pressure difference is produced between the interior and the exterior of the rotary body 2 or cylindrical framework to cause the hedro to flow into the interior through the permeation hole 3 and a lower end of the rotary body.

Title: Supply stand for wire
Inventor: SAITO SATOSHI
IPC: B21C47/16
Filed: 1986-06-13
Abstract: PURPOSE:To install a supply stand of a wire to a usual floor surface so that height of a swift is scarcely varied in its horizontal or vertical attitude, by constituting the supply stand so that a tilting body is driven forward and backward along a horizontal rail and a rear-up rail. CONSTITUTION:At the time of tilting a swift 29 to a horizontal attitude, a driving chain wheel 9b is rotated in the direction as indicated with an arrow A by starting a motor 14, and a front wheel shaft 21 which has been fixed to a tilting frame body 18 is moved backward through a chain 27b. By this movement, a front wheel 22b moves backward straightly by using a vertical member 3b as a rail, but since a rear wheel 25b of the tilting frame body 18 moves upward along a rear-up rail 15b, the tilting frame body 18 becomes a rear-up inclination, and in the end, it is tilted until an attitude of the swift 29 becomes horizontal. In this regard, in the case of returning the switch 29 which has held the horizontal attitude, to the vertical attitude, it can be executed by reversing the motor 14 and moving forward the front wheel shaft 21 through the chain 27b.

IPC: H01L21/3063
Filed: 1986-06-16
Abstract: PURPOSE:To eliminate the step of connecting leads with a semiconductor substrate by supplying charge to the substrate to be etched with charged particles added to an etchant. CONSTITUTION:An electrode 10 is set to a positive potential by applying a DC voltage thereto, and charged particles 12 added into an etchant 1 is positively charged by the electrode 10. A filter 9 has a function for stopping the particles 12, and the particles 12 exist only in a range between the filter 9 and the inner wall of an etching tank 7.

Filed: 1978-11-09
Abstract: PURPOSE:To obtain the light scanner which is capable of subsequently moving light spot on the one-dimensional or two-dimensional planes and arbitrarily controlling the light scanning speed by using an acousto-optic element and an optical guide. CONSTITUTION:When pulse voltages are applied from a pulse power source 8 to an ultrasonic transducer 2, a pulse-1-form refractive-index-fluctuating portion 5 is produced near the medium surface of a substrate 1 and this propagates at the propagation speed of sound in the medium along an optical guide 3. On the other hand, the light 6 led into the optical guide 3 by a prism 4 advances in the optical guide 3 and when it arrives at the pulse-form refractive-index-fluctuating portion 5, it is refracted and part of light 7 is radiated to outside the waveguide 3. Thereupon, the pulse separation of the pulse power source 8 is so determined as to become equal to the time required for the refractive-index-fluctuating portion 5 to fluctate in the moving range A of right spot and the pulse separation of the light 6 is suitably determined under such conditions, whereby the moving speed of the light spot, i.e., the scanning speed of light, may be selected freely.
