Title: Device for controlling temperature in pipe bending part
Inventor: FUKUDA MASATANE
IPC: F17D3/00
Filed: 2001-01-25
Abstract: PROBLEM TO BE SOLVED: To solve such problems that when a fluid is passed through a complicated piping, the expansion or shrinkage, vibration, temperature and deformation of the piping, and the pressure, impact strength, etc., which the piping receives, vary delicately with the fluid; particularly in the pipe bending part in which the flow path of the fluid is changed, a thermal stress is generated by the temperature difference between the inner and outer walls thereof due to the influence of outdoor temperature to result in cracking of the pipe; further, the expansion or shrinkage of the piping is always generated by the difference between temperatures of the fluid and outside air to deteriorate the piping; and as a result, a trace of crack causes a serious cracking. SOLUTION: The periphery of the pipe bending part 1 is sectioned 2 on a grid, and a temperature sensor and a heat ray plate 3 or electromagnetic plate are arranged on each section. The temperature change in each section is detected by the sensor, or a reference needle to be a measurement standard is provided on each section to detect the change of distance between the reference needles.

Title: Exposure method and aligner and method of manufacturing device
Inventor: OKUNO HIROO
IPC: G03F7/22
Filed: 2001-01-30
Abstract: PROBLEM TO BE SOLVED: To increase throughput, while keeping sufficient exposure accuracy. SOLUTION: When a plurality of exposures are performed repeatedly on one and the same substrate W, control factors for an aligner 102, which are related with throughput are changed by a control system 20 according to an exposure accuracy required for each exposure. For example, when a very high exposure accuracy is required, the control factors are changed into such states (or values) that resolution is more heavily weighted than the throughput, and when the required exposure accuracy is not so high, the control factors are changed into states (or values) such that throughput is more heavily weighted than the resolution. When compared with the case where the aligner 102 is always controlled based on the same control factors, it is clear that throughput can be increased by this method.  The control factors are changed into states (or values) such that the throughput is more heavily weighted, only when the required exposure accuracy is not high, so that the exposure accuracy can be kept at a sufficiently high value.

SOLUTION: The differential transistor 110 of a FET constructing an input terminal of a differential amplifier circuit is made to operate outside a stable operation area (=non-saturation area and area which is in the vicinity of saturation area boundary, where Id changes with Vds and which is not usually used). Thus, Id is made to limitedly operate in a range where gm functions, heat generation due to the loss being the product of Vds and Id is suppressed, and a fluctuation due to the heat generation is eliminated to suppress low frequency noise.  A level shift circuit 200 consisting of a reference generating part 220 for generating a reference voltage with the potential of the low potential side terminal of the differential transistor as reference potential and a voltage shift part 210 made to operate by the reference voltage and for performing voltage drop is inserted as a means for operating the differential transistor outside the stable operation area, and Vds applied to the differential transistor is thereby determined.
