IPC: G05B19/18
Filed: 1988-09-14
Abstract: PURPOSE:To secure the coincidence of the axis control characteristics between a spindle motor and a servo motor or to return these characteristics to their original states by using a 1st G code which functions to secure the coincidence of the axis control characteristics between an axis C and a feed axis and a 2nd G code which returns the axis control characteristics of the axis changed by the 1st G code to the original state.

A processor 11 reads the NC data on the i-th block (initial value of i = 1) out of the RAM 13 and checks whether this data shows the end or not. If not, the presence of a G code Gg1 or a G code Gg2 is checked. When the presence of the code Gg1 is confirmed, the acceleration/deceieration time constant of a feed axis is changed to Tg or Tc. This time constant is held hereafter until the code Gg2 is commanded. The servo control of the feed axis is performed by means of the time constant Tc and the servo loop gain Kc. While the constant Tc is changed to the constant Tg together with the gain Kc changed to the gain Kg. Hereafter the gain Kg is held until a command is received from the Gg1.

IPC: G02B6/42
Filed: 1997-08-27
Abstract: PROBLEM TO BE SOLVED: To transmit an optical signal pumped from an optical semiconductor element accurately to an optical fiber by forming an antireflection film on the inner surface of a case for encasing an optical semiconductor element. SOLUTION: A case comprising a base 1 having a frame part 2 at the outer circumference on the upper surface, and a cover 3 is applied, on the inner surface thereof, with an antireflection film 10 for preventing an optical signal pumped from an optical semi conductor element S from being reflected on the inner surface of the case. The antireflection film 10 is formed by laminating a plurality of layers having different refractive index. When the refractive index of each layer is set in the range of 4.0-1.0, the antireflection film 10 absorbs the optical signal irradiated from the optical semiconductor element S toward the inner surface of the case with extremely high efficiency thus preventing effectively the optical signal from being reflected on the inner surface of the case toward an optical fiber 8.

CONSTITUTION:When one coin is put in, only a linear light source 10 at the third position from above emits light; i.e., an optical fiber 11 emits red light as a red light source 12 corresponding to a center scoring line 19 emits light. Similarly, when two coins are put in linear, 7 light sources 10 except those at upper and lower ends i.e., three linear light sources 10 emit light and when three coins are put in all the linear, light source 10 emit light. Then, a player visually recognizes light emitted from the linear light sources 10 while posing his field of view on a reel window 40 and recognizes the scoring line 19. Among the linear light sources 10 which emit light when coins are put in, after a game is completed, those which correspond to the scoring line 19 where a combination of patterns for scoring is made, i.e., a blue light source 13 emits light and thereby the optical fiber 11 emits blue light, and the player sees light emitted from the linear light sources 10 and recognizes the scoring pattern.
