Title: Optical device for condensing and optical additive device to be added thereto as well as measuring apparatus using the same
Inventor: TAKADA KATSUHIRO
IPC: G02B27/40
Filed: 1993-09-14
Abstract: PURPOSE:To expand an effective range of depth of focus by providing the optical device with a phase control means for dividing a luminous flux to an inner disk-shaped part and an outer ring band part and imparting a specific phase difference to the light beams transmitted respectively through these parts. CONSTITUTION:For example, a vapor deposited thin film 2 is added to the disk-shaped central part which is enclosed by a radius (r) (r=a/2<1/2>) of a lens system 1 for condensing having an exit pupil of a radius (a) and allows the transmission of >=50% of total incident energy in such a manner that the phase difference of half the wavelength is generated in the light passing the central part and the peripheral ring band part. The total sum of the amplitude of the part where the phase difference is given and the part where the phase difference is not given acts to negate each other in the position of the focus F and, therefore, the concentration of the light at the focus F attenuates. On the other hand, the ring band phase difference generated by the misalignment of the focus and the phase difference given by the vapor deposited thin film 2 act to negate each other at the point D deviated by 2f<2>lambda/a<2> the optical axis direction from the focus of this optical system and the diffractecl light distribution as if the focus moves to the point D is generated.

Abstract: PURPOSE:To certainly complete preheating of a vaporizer and shorten an idle time period between the time of preheating completion and the reserved time by a method wherein two or more preheating time periods of a vaporizer are stored in a controller corresponding influent water temperatures, one of preheating time periods is selected according to the influent water temperature, and a vaporizer start-up time is set at a time prior to the reserved time. CONSTITUTION:When a hot-water supply utilization reserved time T1 is set by a reservation setting device 21 of a remote controller 20, controller 30 reads the influent water temperature detected by an influent water temperature sensor 18 into a microcomputer, and judges whether t<t1, t1<=t<=t2 or t>t2. When the influent water temperature t is lower than t1, a longest time period M1 is selected from the vaporizer preheating time periods previously stored. When the influent water temperature t is between t1 and t2, a medium time period M2 is selected, and when the influent water temperature t exceeds t2, a shortest time period M3 is selected. A vaporizer preheating start-up time T2 is calculated using the selected vaporizer preheating time period M. When the vaporizer preheating start-up time T2 is decided by calculation of an arithmetic expression T2=T1--M, the electric heater 6 is turned on at the time T2.
