Inventor: UETSUKA NAOTO
IPC: G02B6/26
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To manufacture an optical waveguide in which the low-reflection grating having rectangular spectrum characteristics is formed. SOLUTION: This optical waveguide 5 is so constituted that a core 5a where a grating having a periodic uneven refractive index distribution in the propagation direction of light wherein light of specific wavelength should be reflected is formed is covered with a clad 5b which has a smaller refractive index than the core 5a. In this case, many gratings G which have different periods are superposed on the core 5a of the optical waveguide 5a to generate beats, and the envelope of the beats has a shape close to sin(X)/X based upon a line representing an increment of the mean refractive index of the core as an X axis, so the low-reflection grating is obtained which has rectangular spectrum characteristics of the refractive index distribution.

IPC: B41J2/505
Filed: 1986-02-14
Abstract: PURPOSE:To facilitate reprinting after occurrence of an error, by setting a font to be used for a top part of a page, on a job basis. CONSTITUTION:When an error such as a paper jam occurs, pages at unfixed part b-c and an untransferred part a-b become unable to be used, and it is necessary to perform reprinting from a point before the page corresponding to a point (c). For example, where a font number 2 is set by a switch group, Front 2 is selected at the top of each page irrespective of a command received from a host device, and although a font to be used first for page n+1 is changed to Font 2, no command is issued from the host device, and Font 2 is automatically selected by a printer-controlling circuit 14. Also when starting reprinting from page (n), printing is conducted starting from the top of the page, so that a font 2 is automatically selected, and accordingly, it is unnecessary to additionally issuing a command for designating the change of the font to be used.

Title: Axle fixation control device for industrial vehicle
Inventor: MURASE NOBORU
IPC: B60G1/02
Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To ensure a good riding comfortability even if a lateral noise comes in by outputting a fixation operation signal when absolute values of first and secodn centrifugal forces computed are not less than a standard value, and stopping outputting a signal when the condition that both forces are not more than the standard value has passed a specified time or more. SOLUTION: It is determined whether absolute values of a first centrifugal force Fa and a second centrifugal force Fb computed are larger than a first standard value L1 or an absolute value of a difference between both the forces Fa, Fb is larger than a first comparison standard value K1, and when any one of the absolute values is larger than that, a fixation operation signal is outputted (S7-S10). When the condition that absolute values of the forces Fa, Fb is smaller than a second standard value L2 and an absolute value of a difference between both the forces Fa, Fb is smaller than a second comparison standard value K2 has passed a specified time T, outputting the fixation operation signal is stopped (S11-S16). Accordingly, even if noise generates in the centrifugal force on the way of turning operation of a vehicle, the turning feeling can be improved without being influenced by the noise.
