Title: Apparatus for sterilizing and clarifying bath water
Inventor: SANADA SO
IPC: A47K3/00
Filed: 1989-04-28
Abstract: PURPOSE:To carry out a sterilization and clarification of bath water by installing a filtering circulation path connected with a suction side of a main circulation path through a filter and by installing an ozone inlet port at the suction side of the main circulation path. CONSTITUTION:Ozone introduced into a suction path 21 side is agitated, atomized and made to increase its contact area with water by an impeller 11 in a centrifugal pump, because the centrifugal pump is applied as a circulation pump 10. A branching port 31 of a filtering circulation path 30 is installed at an outside wall of the casing of centrifugal pump nearby a discharge opening of a spiral chamber. Most of ozone bubbles, which are subjecting to an outward force in the centrifugal pump due to a centrifugal force, is, therefore, transported to the filtering circulation path 30 through the branching port 31. Ozone is brought into contact with the circulating water for a sufficient time during the passage through the filtering circulation path 30, so that a sterilization efficiency is improved and an adverse influence on human body is also prevented thereby.

IPC: B66B13/14
Filed: 1988-05-10
Abstract: PURPOSE:To perfectly prevent generation of troubles due to overload by repeating opening/closing motion of a door so as to reduce the load on the motor, when the overload condition is generated on the motor for driving the door and a detecting device for overload is actuated. CONSTITUTION:For example when a small stone is in a seal groove and a door is obstructed to close, because of excessive lock current on the motor due to actuation of a contactor for closing door 10a, torque switches Ts1, Ts2 are on, a closing side inversion relay 101R is on and self-held, an opening/closing command relay 100 is off, and opening motion of the door is carried out. And at full opening and an opening end switch OLS off and the relay 101R off, an elevator operating timer T is off, the opening/closing command relay 100 is on again. The above-stated motion is repeated untill the stone is removed. After six times repeating of this motion, an alarm device X is actuated by output from a counter C and it is informed to a control room. Besides, at opening door motion same action is done. Hereby, generation of troubles due to overload can be prevented.

Title: Instrument for measuring ultraviolet rays for curing coating resin of device for curing resin for coating optical fiber
Inventor: MAEDA KEIGO
IPC: G01J1/42
Filed: 1985-05-24
Abstract: PURPOSE:To make possible the direct measurement of the quantity, illuminance, etc. of UV rays by providing an optical transmission body having a light incident end and light exit end and a UV ray measuring system. CONSTITUTION:The optical transmission body 11 is inserted into a transparent pipe and the quantity, illuminance, etc. of the UV rays in the pipe are measured.

The sensor 17 detecting the UV rays inputs the measurement signal corresponding to the quantity of the detected light to a measuring calculator 18. The calculator 18 which receives said signal determines the quantity, illuminance, etc. of the detected UV rays in the pipe by an electrical or electronic arithmetic processing. The measuring accuracy is thus improved.

Title: Signal processing for eddy current flaw detection
Inventor: OOKI TOSHINORI
IPC: G01B7/00
Filed: 1986-05-14
Abstract: PURPOSE:To achieve a higher reliability of flaw detection by distinguishing a defect from noises, by removing signals from all of a plurality of probes as extraneous noise when exceeding a set level during the same period to detect signals from the respective probes. CONSTITUTION:A plurality of probes n01, n02... and n04 are arranged on an eddy current flaw detecting machine along the axis of a material P to be inspected. The material P being inspected is advanced in the direction (a) of the arrow and the probes n01, n02... and n04 are turned in the direction (b) to detect flaws. For example, shaded spiral belts indicate flaw detection zones of the probe n01 and the intensity of a signal is detected along an angular position of the flaw detection zone. At this point, extraneous noises are removed from data as they heighten a peak value in all of the probes n01-n04 during the same period. However, since a plurality of defects will not exist regularly on the same circumference, signals from the respective probes n01, n02... and n04 are divided into very small time units to distinguish a defect from extraneous noises according to the pattern of changes in the signal. This enables highly accurate detection of any fine defect.

Title: Variable power exposing device for image forming device
Inventor: YASUDA YUJI
IPC: G03G15/041
Filed: 1989-04-28
Abstract: PURPOSE:To prevent an image forming device such as copying machine, etc., from being made large in size by cooperating a 1st reflection mirror with a lens positioned behind the reflection mirror in the case of variable power copying. CONSTITUTION:The position of the lens 4D is changed by interlocking with the movement of the 1st reflection mirror 4C. Then, by interlocking with the movement of the 1st reflection mirror 4C, the position of a 2nd reflection mirror 4B is changed in a direction perpendicular to the surface of the reflection mirror 4C and the horizontal status of a unit for supporting the 1st reflection mirror 4C is adjusted. By moving the 1st reflection mirror 4C in a specified direction in accordance with variable power rate in the case of variable power copying, the lens 4D moves by interlocking with the 1st reflection mirror 4C in the same direction as the mirror 4C at the rate in accordance with the moving quantity of the mirror 4C. Thus, the copying machine incorporating the exposing device is prevented from being made large in size.

Title: Modified method for producing flush-bonded fabric sheet
Inventor: FUJIWARA TAKESHI
IPC: D04H1/724
Filed: 1995-05-10
Abstract: PURPOSE: To provide a method for producing a flush-bonded fabric having variously specified width while keeping the number of flush bonding spindles and spaces between spindles. CONSTITUTION: In the production of flush-bonded fabric, the width of each web of a single spindle is changed by rotating a rotary dispersion board in an identical manner for all spindles. Further, the relative position between a net-shaped filament ejected from a spindle nozzle and the rotary dispersion board, that is the position of a single spindle web on the collection net, is changed by moving the rotary dispersion board in the lateral direction of a sheet to change the lateral distance between the single spindle webs so that each single spindle web overlaps to another by the length of an Lb part at each end of the single spindle web. Thus, a web having an arbitrary width is produced while the homogeneity of the whole sheet is kept.
