Filed: 1999-06-15
Abstract: PROBLEM TO BE SOLVED: To provide an exposure method and an aligner for obtaining a high- resolution pattern in a desired shape, through double exposure by using a pair of masks including phase shifting regions with different phase shift effects. SOLUTION: A first exposure for exposing a resist through a first mask with a shading part and a non-shading part, and a second exposure for exposing the resist through a second mask with a shading part and a non-shading part are provided. Each non-shading part of the first mask and the second mask is the same pattern in shape, and during these exposing steps the resist is not developed. The first mask is so constituted that a phase difference in odd- number times π is applied substantially to light through adjoining regions in at least a first direction at the non-shading parts with the shading part in between, when the light is transmitted through these regions.  The second mask is so constituted that a phase difference of odd-number times π is applied substantially to light through adjoining regions in at least a second direction other than the first direction at the non-shading parts with the shading part in between when the light is transmitted through these regions.

IPC: G01F15/04
Filed: 1991-07-09
Abstract: PURPOSE:To enable measurement of a flow rate to be conducted with a low source voltage and to realize highly-precise temperature compensation without enlarging a current capacity of a power circuit supplying a power to a control circuit. CONSTITUTION:Temperature-sensitive resistant bodies 7 and 8 are provided in a suction air passage. A power transistor 5 is controlled so that the temperature of the temperature-sensitive resistant body 7 be higher by a prescribed temperature than that of the temperature-sensitive resistant body 8. An operational amplifier 230 is constructed as a voltage follower circuit and a current is supplied from an emitter of the power transistor 5 to the temperature-sensitive resistant body 8. Thereby the amount of electrification of the temperature- sensisitive resistant body 8 for temperature compensation is controlled in a stable manner and highly-precise temperature compensation is executed. Since the current to the temperature-sensitive resistant body 8 is supplied from the emitter of the power transistor 5, besides, it is possible to enlarge a resistance value of a resistor 3, to lessen the current capacities of Zener diodes 101, 102 and 103 and thereby to reduce the area of an element. A circuit thus constructed is suitable for circuit integration in particular.

Title: Recorder
Inventor: KITAMURA TAKASHI
IPC: B41J2/44
Filed: 1979-12-26
Abstract: PURPOSE:To decrease the influence of edge effect by providing a means of making an original image on a recording body and a means of overlaying network dots through light beam scanning, converting the large area image to the aggregation of dots and recording the same. CONSTITUTION:The image of an original 1 is formed on a photosensitive drum 10 by an imaging lens 2, and at the same instant, the modulated laser beam is scanned. The laser beam is outputted by being added with an LBP mode and a rush black  image is segmented by white lines. For the period r1 of spacial network dots and the  width r2 of the white lines, it is desirable to set the size of r2 of the white parts at  r2<<r1 because the decrease in resolution occurs when the white frames are sufficiently resolved since these are made into the dots when the output paper is  viewed by the human eyes. Even if the size of the white frame parts is made sufficiently narrow, the electrostatic image is resolved sufficiently, and is not resolved  in development and transfer, thus no uncomfortable feel is caused by the dots when  viewed by man.
