Title: Filter bag and filtration device using the bag
Inventor: SENDA TERUO
IPC: A01J11/06
Filed: 1994-12-26
Abstract: PURPOSE: To provide a filters bag capable of removing solid impurities from an untreated liquid at high removal rate and a filtration device using the filter bag. CONSTITUTION: A filter bag 7 consists of filter cloth formed in a bag shape, with an extremely fine fiber of 0.1 to 20μm thickness obtained by napping a woven or a knitted base material, bristling up on the surface of the base material. In addition, this filter bag 7 is attached, in a freely detachable manner, to one end of a pipe coupling for the inflow of an untreated liquid disposed on an untreated liquid inflow port side, using a fixing band 8. The untreated liquid flowing into the interior of a cylinder 1 from the pipe coupling 2 is caused to pass to an opposite face side to the napped fiber face 7a side with the filter bag 7. A filtrate thus obtained is extracted from a pipe coupling 9 for the outflow of a filtrate.

IPC: G02B15/16
Filed: 1993-12-28
Abstract: PURPOSE:To reduce burden on an objective lens group and to easily perform aberration correction even when miniaturization and a high variable power ratio are attained by relating a condenser lens group without contributing to the temporary imageforming of the objective lens system in a conventional system to the temporary image-forming. CONSTITUTION:An inverted image constituted of a positive objective lens group 11 and a positive condenser lens group 12 is image-formed on a primary coupling surface 13, and the inverted image is erected on an erect optical system 14 consisting of a polyprism and a mirror, etc., and it can be observed via a positive eyepiece group 15. The condenser lens group 12 is separated from the primary coupling surface 13 by distance (s). By employing such constitution, the condenser lens group 12 bears the power of the objective lens group 11. Therefore, it is possible to bear a power load by both condenser lens group 12 and the objective lens group 11, which facilitates the aberration correction.

Abstract: PURPOSE:To maintain a condition in which flashing light emission is possible constantly by providing a first and second voltage detection circuit to monitor a charge voltage of a main capacitor, stopping charging when a first voltage is reached, and restarting charging when it is decreased to a second voltage. CONSTITUTION:At the time of charging, a controller 20 puts on a switch 70, it makes a charge up display, it monitors a voltage detection circuit 80, and when a charge voltage of a main capacitor 60 reaches a first voltage V of a specified value, it gives instruction to stop charging to a step up inverter 40 to put the switch 70 off. After stopping charging, the controller 20 puts on the switch 70 every specified time to monitor a voltage of the capacitor 60, and when it is decreased to a second voltage V, it gives instruction to restart charging to the inverter 40. A device can thus be maintained in a condition in which flash light emission is possible constantly, and a leak current is restricted to reduce consumption of a battery.

Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To provide an energy spreading device with improved security by using a spreading code and converting signals to energy averaged signals. SOLUTION: A spreading modulation part 4 spreads and modulates the signals b(t) to energy averaged modulation signals s(t) by using the spreading code c(t). That is, first and (m)-th spreading code generation parts 1a and 1m repeatedly generate the M (maximum cycle) sequence code of 1023 clock cycles the like by the spreading code, an order 10 for instance. By switching a switching part 2 by a switching cycle generated by a cycle generation part 3, the 1023 clock cycles or the like for instance, the different spreading code c(t) is obtained for each switching cycle. The spreading modulation part 4 modulates the signals b(t) by the spreading code c (t) and obtains the modulation signals s (t.) In such a manner, since the plural spreading codes are switched and used, the spreading code is hardly decoded and the high level of the security is kept.

IPC: G02F1/1335
Filed: 1989-12-28
Abstract: PURPOSE:To prevent the generation of the connection defect arising at the time of heating and press welding of transparent conductive films and external terminals by forming color filters on the transparent conductive films patterned on a substrate, then forming the transparent conductive films again on the color filters and conducting the upper and low transparent conductive films holding the color filters in-between. CONSTITUTION:The color filters 3 consisting of a polyester melamine and dyes are formed by an electrodeposition method on ITO electrodes 2. The film of transparent electrodes 4 is then formed by an ion plating method. Numerous fine holes are bored in the color filters 3 in the case of the electrodeposited color filters and if the molecules having the high energy of the transparent electrodes by the ion plating method collide against these color filters, some of the molecules penetrate down to the transparent electrodes of the lower layer of the color filters 3 in the numerous hole parts and the upper and lower transparent electrodes are electrically conducted. Thus, the utilization of the ITO 2 under the color filters 3 as terminal electrodes for connection is possible and, therefore, the defects by the thermal stresses applied at the time of press welding for sealing and the connection to external electrodes are prevented.

Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To reduce a cutting resistance by having a groove of a specific width fanned in the cutting blade tip end direction of a breaker projection as well as providing a breaker projection near the cutting blade tip end. SOLUTION: In the case of a cutting insert I, a groove 9 is formed in the cutting blade tip end 8 direction of a breaker projection 8, as well as providing the breaker projection 8 near the cutting blade tip end 5. As the result, cut chips enter from the front opening 9c of the groove 9 into the groove 9, and slide up on the groove wall surface 9a on the progressing direction side or hook on the ridge side 9b at the groove upper end so as to make a curl in a spiral shape. In this case, since the cut chips hit the groove wall surface 9a or groove ridge side 9b slantly, a cutting resistance is small. Meanwhile, as the width W of the groove 9, such a size from 0.3mm to 0.8mm is desirable.
