IPC: G03B13/28
Filed: 1980-02-18
Abstract: PURPOSE: To obtain a miniature focusing plate which causes no mechanical vibration by arranging thin prism pieces which diffract light in different directions and by providing a light control element which controls the passing and shielding of light corresponding to respective thin prism pieces.  
     CONSTITUTION: Focusing plate 4 consists of prism 4g composed of two kinds of thin prism pieces, differing in direction by 180°, arrayed by turns and a light control element which controls the passing and shielding of light corresponding to respective thin prism pieces. Liquid crystal cell 4d of this focal plate 4 is applied with an AC voltage by an electronic circuit via transparent electrodes 4b and 4c at a low frequency enough to follow up switching on-off operation by the eyes. Then, incident light I 0  to focusing plate 4 is emitted in direction I 0 ' when the voltage is not applied and in direction Iv' when the voltage is applied. In this case, as the out-of-focus degree increases more and more, the degree of the separation into two diffracted images also increases more and more, and in focusing, no separation appears. Therefore, the focusing state can be obtained by adjusting the zooming of the photographic lens so that it will be stationary.

Title: Heater device
Inventor: SAKURAI TOSHIO
IPC: F24F13/28
Filed: 1989-01-27
Abstract: PURPOSE:To enable a Hall IC and a magnet to be also used as a sensor for use in sensing a clogged state of a filter by a method wherein a controller for decreasing or terminating combustion in a burner is provided when a duty ratio of wave outputting from the Hall IC is less than a predetermined value. CONSTITUTION:In the case that a filter 3 is clogged, air passing through the filter 3 is reduced. A fan motor 6 is not sufficiently cooled by this air, resulting in that a temperature of the fan motor 6 is increased. As this temperature is increased, a temperature of a permanent magnet 13 fixed to the fan motor 6 is also increased. As this temperature is increased, a strength of a magnetic field from the permanent magnet is weakened, so that a duty ratio of the wave- form from the Hall IC is decreased. At a petroleum fan heater, when a duty ratio of the wave-form from the Hall IC is less than 30% (at this time, a temperature of the fan motor 6 is higher than about 110 deg.C), a controller 10 may control a discharging amount of a pump in such a way as a combustion in the burner 8 is weakened.
