Title: Optical fiber and optical amplifying method
Inventor: KITAYAMA KENICHI
IPC: G02B6/02
Filed: 1984-10-31
Abstract: PURPOSE:To suppress the daturating phenomenon of gain in an optical amplification using induced Raman dispersion by forming a sub-core applying large loss only to a specific wavelength in addition to a main core. CONSTITUTION:A loss applying part 4 is arranged close to the sub-core 3 along its longitudinal direction. Quartz glass to which impurity such as B2O3 is doped can be used as a base material for applying loss. Sufficient coupling is generated between the wave-guiding modes of both cores 2 and 3 at the secondary stokes wavelength lambdas1 of the induced Raman dispersion and coupling at the pump optical wavelength lambdap=1.318mum and the primary stokes optical wavelength lambdas1=1.401mum is suppressed down to a sufficiently low level to attain wavelength selective coupling. Namely, these coupling can be attained by setting up the core diameters of both the cores and refractive index difference between the core and clad to different values each other.

Title: Heat-fixing device
Inventor: NAKADA TOSHIAKI
IPC: G03G15/20
Filed: 1984-10-30
Abstract: PURPOSE:To stabilize the temperature control of a heating roller, by enclosing a material whose melting point is lower than the controlling temperature of the heating roller and higher than the lower limit temperature of the heating roller required when a toner image is fixed to a member to which the toner image is to be fixed, in the heating roller. CONSTITUTION:At the time of heating up, a heating roller 4 is heated by a heater 2 to the melting point of a material 5 enclosed in the heating roller 4 and set to a waiting state and the temperature of the roller 4 is maintained until all the material 5 melts. When the heating roller 4 is further heated, a temperature sensor 3 detects the temperature of the roller 4 and a control circuit maintains the heating roller 4 at a previously fixed heating roller controlling temperature. When the waiting state is shifted to the fixing state thereafter, the heat of the roller 4 is absorbed by a pressing roller 1 and member to which a toner image is fixed and, because of the insufficient capacity of the heater 2, the temperature 7 of the heating roller 4 drops. But the material 4 enclosed in the roller 4 generates heat of solidification and drop in temperature to a level lower than the melting point of the material 5 is prevented. Therefore, the heating roller temperature 7 can be controlled stably at the time of fixing.

Abstract: PURPOSE:To automatically shut-off the titled device when switching a normal running to a reverse running, in case a claw for a B face does not exist, by detecting by a detecting lever for the B face whether the claw for the B face exits or not, when switching the normal running to the reverse running, and switching a shut-off mechanism to a state of non-operation/operation in accordance with whether the claw for the B face exists or not. CONSTITUTION:When a control lever 210 is oscillated in the direction as indicated with an arrow D' from a state as shown in the figure, in which a switching lever is moved to a reverse position, one end edge 204a of a long hole 204 of a detecting lever 190 for an A face is pressed by a pin 211 of the lever 210, and the detecting lever 190 is brought to a forward motion in the direction as indicated with an arrow B and controlled at a lock release position. On the other hand, a detecting lever 191 for a B face is not controlled by the pin 211 of the control lever 210 but made to be able to execute a reciprocating motion between arrows C, C'. Accordingly, when the switching lever is in the reverse position, the detecting lever 191 for he B face detects independently a claw for the B face, and when the claw 174 for the B face does not exist, the detecting lever 191 is brought to a backward motion at a lock position in the direction as indicated with the arrow C' by a spring 197.

Title: Signal generation system
Inventor: SHIMOZONO RIYOUJI
IPC: H03B28/00
Filed: 1983-12-05
Abstract: PURPOSE:To generate a sine wave of frequency other than higher harmonics by inverting the sign of a digital signal of frequency FsHz obtained by sampling a sine wave signal of FHz at intervals of one sample data. CONSTITUTION:A memory M is stored with sampling data on sine waves of several frequencies. When the frequency FHz is specified from an input line (f), a control part C reports the address area of the memory M to an address counter AD. The counter AD generates addresses of reported areas successively and sends them out to the memory M. The sign-bit output line S of the memory M is connected to a sign inversion part SI, which outputs an arrival sign bit as is inputted with a signal Cs from the control part C. When a frequency (Fs/2-F) Hz is specified, the control part C sends an indication of the inversion of every other sign bit to the inversion part SI. Thus, the frequency is specified through the specifying signal (f) to generates a digital signal consisting of a sine wave of frequency FHz or (Fs/2-F)Hz.

Abstract: PURPOSE:To reduce the number of sorting times and to speed up the surface- painting processing of a hole polygon by sorting the vertexes of the polygon into peak vertexes, ravine vertexes and continuous points, sorting the peak vertexes in the order of height and sequentially surface-painting from the highest peak vertex. CONSTITUTION:A vertex sorting part 11 sorts the vertexes of the polygon into the peak vertexes, the revine vertexes and the continuous points, and a peak vertex sorting part 12 sorts 'Y' of the peak vertexes. A part for deciding right and left of sides 13 decides to which side either a left or right of the peak vertex a side connecting to the peak vertex is connected with, and a polygon division part 14 decides the temporary stop point of surface-painting. A stack 15 temporarily preserves surface-painting data and a table 16 connects surface-painting data. Namely, it once sorts 'Y' so that the peak vertexes are in the order of height. Thus, the number of sorting times can be reduced and the whole surface-painting processing speed can be improved.
