Abstract: PURPOSE:To easily adapt an omnidirectional mobile vehicle to a wide range of transport jobs by adding a turning mechanism at the lower part of the body of the mobile vehicle and attaching a guide path sensor to the turning mechanism to sense the signals received from a guide path. CONSTITUTION:The turning drive power of a turntable turning motor 2B and the turning direction of the motor 2B are transmitted to a 2nd gear 2D from a 1st gear 2C via a turning mechanism 2. Thus a turntable 2A is turned in accordance with its turning direction. At the same time, two pairs of guide path sensors 5 are set centering a guide path 7 (8) and before and after of the turntable 2A respectively. Then the sensors 5 of an omnidirectional mobile vehicle 1 are turned by the mechanism 2 and subject to the lateral guide path. At the same time, the wheels of the vehicle 1 are also turned.

Abstract: PURPOSE:To manufacture a film at high speed without deteriorating uniformity in thickness and transparency, by melting and extruding polycoupleamide resin containing a metallic compound and having special fusion specific resistance and methanol extractable content. CONSTITUTION:A metallic compound is ethylene ionomer resin and an alkaline metal, an alkaline earth metal, an aluminum group element, a halide of a transistion metal, an oxyacid compound of sulfur, an oxyacid compound of phosphorous, a hydroxide, organic carboxylic acid and organic sulfonate are available.

Filed: 1985-07-26
Abstract: PURPOSE:To increase the suction amt. of the fluid to be treated and to increase the treating capacity of an ejector device which sucks the fluid to be treated by the ejection of a driving liquid by forming a nozzle to a toric shape to eject the liquid into an annular shape. CONSTITUTION:The nozzle 22 is disposed in a large-diameter part 20 of a flow passage 10 and a pipe 24 connecting thereto is connected partly through the large-diameter part 20 to a driving liquid pump. Since the nozzle 22 is made into the toric shape, the driving liquid has approximately the annular shape in the flow passage 10. The driving liquid 200 instantaneously stagnates once in a reservoir part 22a from a pipe 24 and is then discharged by the pressurizing force from a ring slit part 22b into the passage 10 under the pressure uniform over nearly the entire circumference when the pump is driven. As a result, the fluid 100 to be treated is effectively sucked and the driving liquid ejected to the annular shape on the down stream of the nozzle 22, i.e., the cleaning liquid is efficiently mixed with the waste liquid which is the fluid to be treated.

Title: Charging circuit

Filed: 1995-06-30
Abstract: PURPOSE: To make it possible to increase the resistance value of a detecting resistor for detecting a secondary current, by providing a transformer with a tertiary coil, in which a current in proportion to a secondary current is flowed and connecting the detection resistor to the tertiary coil. CONSTITUTION: A diode 25 and a detection resistor 26 are connected to a tertiary coil 13T of a transformer 13 to form a closed circuit. Then a tertiary current in proportion to a secondary current at a secondary coil 13 is flowed at the detection resistor 26. Since the secondary current is detected at the detection resistor 26 that is connected to the tertiary coil 13T, the decrease in charging effect can be prevented even when the secondary current becomes small. Since the resistance value of the detection resistor 26 can be made large, a current at the detection resistor 26 is made small, and the loss in power caused by the detection resistor 26 can be made small.

Abstract: PURPOSE: To restrain a toner image from being reversely transferred in the case of laminating and transferring the toner image by electrifying the surface of an intermediate transferring medium to the same polarity as that of the toner image every time the toner image on a latent image carrying medium is transferred on the intermediate transferring medium. CONSTITUTION: A first electrifying means 2 uniformly electrifies the surface of the latent image carrying medium 1, and a pre-transfer electrifying means 5 electrifies the developed toner image and the surface of the medium 1 to the same polarity as the charge polarity of the toner image. By the pre-transfer electrification, the toner image is pressed by electric field strength, attracting force between the medium 1 and the toner image is increased, so that the flowing and the thickening of the toner image are prevented. Furthermore, a second electrifying means 8 evenly electrifies and processes the surface of the intermediate transferring medium 6 to the same polarity as that of the transferred toner image every time the toner image is transferred to the intermediate transferring medium 6 from the medium 1.  The dielectric thickness of the surface insulating layer of the medium 6 is <=5μm, so that surface potential is not fluctuated with respect to the electrifying process, repulsive force works between the toner image and the medium 6; therefore, the reverse transferring can be restrained.
