Title: Multi-focus double diffraction lens system
Inventor: FIALA WERNER J
IPC: G02B27/00
Filed: 1988-09-21
Abstract: PURPOSE: To improve the degree of freedom of choices of the lightness, color, and enlargement rate of an image by employing a multifocal achromatic birefringent lens system which has at least two focal lengths selected independently of each other and suppressing an undesired focus at a maximum. CONSTITUTION: A multifocal chromatic and an achromatic birefringent lens system consist of many permutations and combinations of birefringent lenses and other birefringent lenses or isotropic lenses. For example, an isotropic lens 10 having spherical surfaces R1 and R2 and an isotropic lens 30 having spherical surfaces R3 and R4 are in front of and behind a birefringent lens 20 having spherical surfaces R2 and R3 . Then at least two focuses can be selected in advance and are positioned along the same lens axis to light which is made incident in parallel to the lens axis, and the curvature of one of the 1st and 2nd lens is selected independently of the previously selected focus. Consequently, wide-range multifocal optical designing which complies with any request for practical use becomes possible.

Filed: 1999-08-23
Abstract: PROBLEM TO BE SOLVED: To provide an image recording and reproducing device having functions of detecting an attitude, hand shake, or the like without arranging an attitude detector for detecting the attitude. SOLUTION: The image recording and reproducing device 20 is provided with a moving part 21 and detects variation in the attitude of the image recording and reproducing device 20 by polarity of an electric signal of a driving circuit of the moving part 21, generated by a change in a direction of a gravity load to the moving part 21 caused by the change in the attitude of the image recording and reproducing device 20. Thus, since the change in the attitude of the image recording and reproducing device 20 can be detected from the polarity of the electric signal in the driving circuit of the moving part 21 generated by the change in the direction of the gravity load to the moving part, this eliminates the need for newly arranging a device for detecting the attitude, and as a result, the image recording and reproducing device can be reduced in size and further in cost.

IPC: F24S90/00
Filed: 1983-12-14
Abstract: PURPOSE:To permit to retrieve vapor into an expansion tank by a method wherein the vapor is condensed in a vapor pipe equipped with a radiator in case the amount of vapor generated in the heat collector during a heat collecting pump is being stopped is small. CONSTITUTION:When the heat collecting pump 20 is stopped due to electric power failure or the like, heat medium in a heat collector 13 is boiled and gas and liquid, contained in the vapor generated thereupon, are separated in the gas and liquid separating section 21 of a pipeline 17, then, the vapor flows into the expansion tank 22 through the vapor pipe 23. The heat of the vapor is exchanged with the same of atmosphere in the radiator 24 and is cooled whereby the vapor is condensed and the liquid is retrieved into the expansion tank 22. At this time, the heat medium equivalent to the generating amount of vapor is supplemented from the expansion tank 22 to a circulating path 9 through a liquid pipe 25. According to this method, the vapor, generated in the heat collector 13, is condensed and returned to the circulating path 19, therefore, reduction due to the evaporation of heat medium and the supplementation therefor may be small. In case the amount of supplementation is small, the reverse flow of the heat medium 18 from a liquid pipe connecting section 27 to the gas and liquid separating section 21 due to the static hydraulic pressure of the expansion tank 22 may be precluded, since a non-return valve 26 is provided between the connecting section 27 and the separating section 21, and the vapor may be introduced from the separating section 21 into the vapor pipe 23.

Filed: 1984-11-09
Abstract: PURPOSE:To widen the band of an ultrasonic wave easily with high precision by setting the pulse width of at least one of burst waves consisting of a pulse group for exciting and driving applied to the piezoelectric element of a transducer different from others. CONSTITUTION:A pulse transmitting circuit 6 transmits a burst signal S1 consisting of a pulse group responding to the control signal of a circuit 14. The pulse width of this wave S1 is set different with time; t1>Tp>t2,t3=t4= Tp, and t5<Tp (Tp: the half period of the natural frequency of an ultrasonic wave determined by shape and thickness of the piezoelectric element), where t1-t5 are the pulse width varying from the beginning of the transmission successively. The width t1 is made longer than oscillation Tp to oscillate the piezoelectric element and give inertia, the width t2 is shortened to increase the frequency and excite and drive oscillation with the same widths t3 and t4 with the oscillation Tp, and the width t5 is shortened to provide dumping effect. Consequently, the frequency component of the ultrasonic wave is widened in band to reduce trailing of the ultrasonic wave. Thus, excellent picture quality is obtained from the shallow part to the deep part of an object.
