Title: Zoom optical apparatus
Inventor: JIEEMUSU JII BEIKAA
IPC: G02B3/02
Filed: 1989-02-15
Abstract: PURPOSE: To make it possible to execute a zoom action and an imaging action in combination by constituting a pair of planar transparent bodies in such a manner that the adjacent planar bodies cross a perpendicular arranged optical axis and have at least one surface not having a rotational symmetry and that these planar bodies move across the optical axis. CONSTITUTION: Each of the planar bodies 16, 18, 20, 22 has the flat surface and the one surface not having a rotational symmetry. The shapes of the surfaces not having the rotational symmetry are so determined that, when the two planar bodies having nearly the same shapes move relatively in a transverse direction, the light refracting power thereof changes continuously and the same effect as the effect of an optical refractive lens having the rotational symmetry is obtainable. The required shapes of the surfaces not having the rotational symmetry may be represented by a polynomial in Cartesian coordinates. The cubic term is required to be nonzero in order to obtain the light refractive power in the case of sliding motion and the quartic term is required to be nonzero in the case of rotational motion. As a result, the zoom action and the imaging action may be executed in combination.

Title: Pachinko game machine
Inventor: ICHIHARA TAKAAKI
IPC: A63F7/02
Filed: 1998-02-18
Abstract: PROBLEM TO BE SOLVED: To achieve a higher operating rate than ever of a pachinko game machine. SOLUTION: The varying of a special pattern (specified event) is conunted and when the second jackpot is presented (YES at step S50), a pattern varying period is set or altered based on counts obtained (at step S56). The setting or altering of the pattern varying period is made to be more advantageous for a player the less the counts are. In this case, when a game is played at a pachinko machine following the second jackpot, the shorter the pattern varying period is made the less the frequency of varying the special pattern. Thus, as more of the frequency of varying the pattern is offered per unit time, the player continues the game to gain greater profit. This achieves a higher operating rate of the pachinko game machine.
