Title: Magnetic card
Inventor: SATO SHINJI
IPC: B42D15/10
Filed: 1994-07-13
Abstract: PURPOSE:To prevent the forgery of a magnetic card by allowing a magnetic head to be inhibited to read the card from the structural point of view. CONSTITUTION:A magnetic recording layer 2 having high coercive force, a foamed ink layer 3 to be expanded by foaming by heating, and a hidden layer 4 having low coercive force are sequentially laminated on a base film f a nonmagnetic material, heated by a burner after a card is used, the ink layer is irreversibly expanded by several times to increase a spacing loss between the layer 2 and a magnetic head (not shown) to be impossible to be read. Hidden ink and foamed ink are mixed in the manufacturing step instead of the spacing loss between the recording layer and the head (not shown), and mere mixed ink layer may be formed.

Title: Variable magnification optical system
Inventor: HIRANO HIROYUKI
IPC: G02B15/00
Filed: 1988-06-29
Abstract: PURPOSE:To simplify the mechanism and to reduce the space by providing an image formation optical system which has a flexible lens varying in surface curvature by deformation, and applying a force to the flexible lens from its outer periphery and deforming the lens while moving the image formation optical system on the whole along its optical axis at the time of power magnification and thus varying the focal length. CONSTITUTION:A power magnification lens is the completely symmetrical system consisting of a 1st group lens 10 with negative power, a 2nd lens group 20 with positive power, and a 3rd lens group 30 with negative power. The image formation optical system is stored in one lens barrel 40 on the hole and moved by a driving means in the optical axis direction on the whole and the power is varied by deforming the 1st and 3rd lens groups 10 and 30. Therefore, while the distance object images is held constant, the power can be varied only by the movement of the whole lens system without any relative movement among individual lenses. Consequently, the mechanism for varying the optical path length is not necessary as heretofore and the need to use a complex lens barrel which uses a cam, etc., is eliminated to reduce the space.

Title: Measuring apparatus
Inventor: HASEGAWA HIROAKI
IPC: G01F15/00
Filed: 1990-06-20
Abstract: PURPOSE:To enable exact and quick adjustment of a reference point by outputting a measuring signal by a switching means through a time constant circuit of a large time constant when the reference point is adjusted and through a time constant circuit of a small time constant when measurement is executed. CONSTITUTION:When an operating switch 4 is turned ON, a switching means 3 is changed over and an output signal of a phase time difference circuit 17 is supplied to a time constant circuit 1 (of a long time constant). A prescribed time later, a zero point is set by a zero adjust circuit 6 and a zero value is stored in a memory circuit 7. After a prescribed time passes, the means 3 is changed over to a time constant circuit 2 (of a short time constant) automatically and transmits a prescribed signal to an output circuit 8. Even when a fluid pulsates or a fluid pressure changes, therefore, the signal is supplied to the circuit 6 through the circuit 1 at the time of zero adjust. Therefore the zero point can be caught with an average value and highly precise setting of the zero point can be executed. On the occasion when zero setting is conducted at a piping site, accordingly, it can be executed precisely with a pump left to be ON. At the time of measurement, besides, changeover is made from the circuit 1 to the circuit 2 and mass measurement with excellent responsiveness can be executed.

Title: Combustion space structure of boiler in which heat absorbing water pipes are arranged in burning flame
Inventor: KOBAYASHI HIROSHI
IPC: F22B7/06
Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To enhance the efficiency of a boiler by providing many heat absorbing water pipes in burning flame, and by performing combustion and heat transfer actions together in the bank of the heat absorbing water pipes. SOLUTION: Many heat absorbing water pipes 2b are arranged in burning flame where the fuel in a flue 1 is burning. When the burning flame which has come out from a burner 8 passes through the heat absorbing water pipes 2b, two actions, which are a combustion promoting action and a heat transfer action, are performed together, and then exhaust gas 6 is exhausted outside through a smoke box 3. In this way, combustion and heat transfer can be completed at the same time within the volume of the combustion space, so that the drum of a boiler can be miniaturized to about half the size of a conventional one. Moreover, the burning flame is cooled down by the heat absorbing water pipes 2b, so that the restraining effect of NOx of about 50% can be achieved even by the same burner.
