Abstract: A contactless power supply system includes a power transmission coil, a power receiving coil, and a center tap that is provided at the power transmission coil. Specifically, the power transmission coil has a first coil and a second coil. The first coil is configured with a first conducting wire that circularly extends from the center tap by winding in a first direction from a first internal circumference side to a first external circumference side. The second coil is configured with a second conducting wire that circularly extends from the center tap by winding in a second direction, which is opposite to the first direction, from a second internal circumference side to a second external circumference side. A first number of windings of the first coil is approximately the same as a second number of windings of the second coil.

Abstract: There is a micro-machining apparatus for removing the micro-machining dust generated at the time of machining while a workpiece M is machined within a liquid W using a probe tip. The apparatus includes a stage on which the workpiece is to be placed; a probe having the probe tip, a machining device having a moving means that moves the stage and the probe relative to each other to machine the workpiece by the probe tip, and a micro-machining dust removing device having a first electrode and a second electrode that are arranged in the liquid so as to sandwich the probe tip therebetween, and a voltage application means that applies a voltage to between both the electrodes to move the micro-machining dust in the liquid.

Abstract: Disclosed is a programmable logic circuit control apparatus capable of managing data with various bit widths and data lengths, generated by various processes to be executed by a programmable logic circuit, with a simple structure. A module address memory section (4) stores data indicating addresses of modules or conditions for branching processes and jump distances page by page. A write address and a read address of an internal data memory (2) are also stored in a page where the address of a module is stored. A circuit control section (5) reads data of each page from the module address memory section (4), and, according to the read data, reads a module, reconfigures a programmable logic circuit and reads data of a next page, or performs jump. When the programmable logic circuit is to be reconfigured, the circuit control section (5) performs an operation of supplying a write address and a read address to the internal data memory (2).

Abstract: A physical group address is allocated to a storage area of a flash memory (11) for each group as units smaller than a block as units of data erasing, and the group includes multiple pages and the page includes multiple columns. When writing data and a logical address of a writing destination are supplied, a CPU (121) writes the data in a column in the group indicated by a writing pointer to associate the supplied logical address with the column. A relationship between the physical group address of the group having this column and the logical group address is stored in a logical/physical conversion table of a RAM (123). Data stored in the block is erased when the number of blocks having no empty block reaches a predetermined number or less.

Abstract: Disclosed is a memory device which is not easily deteriorated and a memory managing method which does not easily deteriorate a memory device. A physical address is given to a memory area of a flash memory (11) page by page. When supplied with to-bewritten data and a logical address where the data is to be written, a CPU (121) writes this data in a page indicated by a write pointer. The correlation between the physical address and the logical address of the page is stored in a RAM (123) in the form of BPT (Block Pointer Table). At the time of reading, the CPU (121) that has been supplied with the logical address searches the BPT to specify a physical address associated with that logical address and reads data from that page which is given the specified physical address. Flash erasing of a block is executed when the number of empty blocks becomes equal to or smaller than a predetermined number.

Abstract: A zoom lens comprising a first lens group having a positive refracting power and its position fixed, a second lens group having a negative refracting power and displacable mainly for magnification, a third lens group having a positive refracting power and its position fixed, and a fourth lens group having a positive refracting power and displacable mainly for correction of the focal position for magnification and focusing.

Abstract: A zoom finder of a real image type has an objective lens having positive refracting power and an eyepiece having positive refracting power. The objective lens is constructed by first, second, third and fourth lens groups sequentially arranged from an object side. The first lens group has positive refracting power. The second lens group has negative refracting power. The third lens group has positive refracting power. The fourth lens group has positive refracting power. The zoom finder is constructed such that a real image is focused and formed by the objective lens between the fourth lens group and the eyepiece and is observed through the eyepiece. A magnification of the zoom finder is increased by moving the second lens group from the object side to an eyepiece side. A change in diopter caused by this increase in magnification is corrected by moving the fourth lens group. In accordance with the above structure, an entire length of the zoom finder is short and is not changed in a zooming operation.

Abstract: A bobbin transporting system includes a spinning bobbin transporting path and an empty bobbin transporting path both provided between a spinning frame and a winder, and a spinning bobbin reservoir path is formed intermittently of the spinning bobbin transporting path between the spinning frame and winder for temporarily reserving thereon all of spinning bobbins on a transport band which have been doffed by the spinning frame.

Abstract: False-twisting equipment including a first heater disposed on one side of an operation space, a second heater disposed on the other side of an operation space and a balloon control device and a false-twisting spindle disposed in the upper portion of the operation space wherein yarn is fed from the one side through the upper portion of the operation space and wound on the other side and the yarn passes through the upper portion of the operation space in a straight line so as to effectively propagete false-twists given to the yarn by the false-twisting spindle. The yarn, and the first heater are disposed as close to the floor as possible and the height of the top of the heater is lowered as much as possible, so that the yarn coming from the first heater to the false-twisting spindle is bent at a bending angle as large as possible.
