Title: Liquid immersion exposure apparatus and method that exposes a substrate via an optical system and a liquid
IPC: H01L21/68
Filed: 2012-08-29
Abstract: A part of a plate (50) of a predetermined shape detachably mounted on a moving body (WST) is detected by an alignment system (ALG) while the position of the moving body is measured by a measurement unit (18 or the like) that sets a movement coordinate system of the movement body, and based on the detection results and the measurement results of the measurement unit corresponding to the detection results, position information of an outer periphery edge of the plate (50) is obtained. Therefore, even if there are no alignment marks (fiducial marks) on the moving body (WST) for position measurement, the position of the plate, or in other words, the position of the moving body can be controlled on the movement coordinate system set by the measurement unit, based on the position information of the outer periphery edge of the plate.

Title: Power converter
Inventor: TANAKA MAKOTO
IPC: H02M7/493
Filed: 1994-05-13
Abstract: PURPOSE:To prevent the steep voltage variation of the commercial-power-supply side of a power converter and the voltage increase of the fuel-cell side which are accompanied by the stopping of the power converter, by reducing the output of the power converter gradually during a certain time period in the case of its stopping, and by releasing its switch after the confirming of its zero output. CONSTITUTION:When a stop-signal transmitter 71 transmits a stop signal, the output signal of a power-reduction-slope setting device 81 is transmitted to a signal switching device 82, and the signal switching device 82 is transmitted from the side of the slope setting device 81. As a result, a power-feed comparator 74 so reduces the reference voltage of an electric-energy setting device 72 linearly during a preset term that the feeding power of a power converter 3 is made zero according to the signal transmitted from the slope setting device 81, and thereby, the feeding power of the power converter 3 is reduced. On the other hand, a zero-power sensor 83 supervises the feeding of the electric energy of the power converter 3 which is indicated by a power sensor 68 while receiving the signal outputted from the stop-signal transmitter 71, and it transmits a signal to a switch releasing commander 75 when sensing the feeding power reduced to zero. Thereby, the commander 75 releases a switch 32 based on the signal transmitted from the sensor 83.

IPC: H01G9/02
Filed: 1995-03-30
Abstract: PURPOSE: To increase coupling strength of a fiber under conditions that a space between fibers is kept by a method wherein a refining solution of paper power increasing agent is impregnated and applied to an electrolytic paper after it was made. CONSTITUTION: With the use of Manila hemp pulp, a circle-net double paper is struck and made. Thereafter, it is soaked in a diluted solution of dialdehyde starch refined with ion exchange resin by a direct roll cotar, and the dialdehyde starch is adjusted for dehydration to a paper by a press roll to be 0.05 to 5wt.%, thereafter it is dried with hot wind. An electrolytic paper of a thickness 20 to 70μm, density 0.20 to 0.70g/cm<3> and pulling strength 1.1kg/15mm or more can be obtained. Thus, it is possible to increase coupling strength of a fiber under conditions that the electrolytic paper keeps a fiber space and considerably increase the pulling strength.

Title: Ignition angle controlling apparatus for contactless igniting apparatus for internal-combustion engine
Inventor: SAGA TOSHIHIRO
IPC: F02P5/155
Filed: 1982-06-11
Abstract: PURPOSE:To obtain characteristics for delaying the ignition timing at the time when the engine speed is high, by determining the ignition timing from the logical product of the output signal of an ignition timing advancing means for advancing the ignition timing when the engine speed is low and that of an ignition timing delaying means for delaying the ignition timing when the engine speed is high. CONSTITUTION:An ignition timing advancing means 300 produces an output signal (g) having characteristics for advancing the ignition timing with increase of the engine speed by use of the constant-current charging and discharging function of a capacitor 11 for calculating the advance angle of the ignition timing. On the other hand, an ignition timing delaying means 400 produces an output signal (i) having characteristics for delaying the ignition timing with increase of the engine speed by use of the discharging characteristics of a capacitor 18 for controlling the delay angle of the ignition timing. The logical product of these two output signals (g) and (i) is detected by an AND-circuit 14 and applied to an igniting thyristor 103. With such an arrangement, it is enabled to provide a simple circuit capable of obtaining characteristics for delaying the ignition timing when the engine speed is high.
