A diaphragm portion 20 causes deflection, when high-temperature fluid pressure acts on the pressure sensing surface A of the diaphragm portion 20. This deflection is transmitted via pressure transmitting members 7, 8 to a deflection sensing member 6 which generates an electric signal in response to a pressure received.The diaphragm portion 20 has a recess portion 21 at its center. The recess portion 21 is symmetrical about a central axis of the diaphragm portion 20. A tip end of the pressure transmitting member 7 is brought into contact with the recess portion 21 at a central point. A tapered portion 2d of the diaphragm 20 has a thickness of t.sub.3 which is not larger than the thickness t.sub.1 of an outer peripheral portion 2b or t.sub.2 of a central bottom portion 2c. Furthermore, a heat insulating plate can be provided on the diaphragm to protect the surface A of the diaphragm portion from heat radiation of high-temperature fluid.

A member having an arbitrary shape having a closed curve can be easily subjected to laser processing within a short time. A lens and a laser processing apparatus equipped with the lens are for cutting a material to be cut into a member having an arbitrary shape having a closed curve and include a convex cylindrical lens which is molded to have a closed path so that a line that connects vertices of a cylindrical surface of the convex cylindrical lens has the same form as the arbitrary shape having the closed curve.

A light-exposure device is provided with a microlens array on which is arranged with a prescribed regularity a plurality of microlenses on which exposure light transmitted through a light source and a mask is introduced to resolve an upright equal-magnification image on a substrate. Upon reaching a prescribed position, the substrate is irradiated with pulsed laser light from the light source, and the substrate is successively exposed, and after the entire area of the exposure region of the substrate is exposed, a relative positional relationship between the microlens array and the mask is successively switched in a vertical direction by an amount of a horizontal pitch of the microlenses, and a subsequent exposure is performed. Exposure with high precision and high resolution can thereby be performed with a short exposure cycle time.

A scanning exposure apparatus uses a plurality of microlens arrays to project a mask exposure pattern onto a substrate. A CCD line camera detects an image on the substrate at this time, and using a first-layer pattern on the substrate as a reference pattern, detects whether or not the mask exposure pattern matches the reference pattern. In a case in which the patterns do not match, the microlens array is tilted from a direction that is parallel to the substrate, and the mask exposure pattern is made to match the reference pattern by using the microlens array to adjust the exposure area on the substrate. When the exposure pattern deviates from the reference pattern, it is thereby possible to detect the deviation during exposure and to prevent an exposure pattern misregistration, thereby enhancing the precision of the exposure pattern in an overlay exposure.

In this microlens array, unitary microlens arrays are respectively stacked onto an upper surface and lower surface of a glass plate, and each of the unitary microlens arrays is supported by an upper plate and a lower plate. Marks for alignment are formed on each of the unitary microlens arrays and on the glass plate, and the unitary microlens arrays and the glass plate are stacked onto each other aligned by these marks. This makes it possible to prevent ununiform exposure in scanning exposure using a plurality of microlens arrays.
