Title: Centering method of optical fibers
Inventor: TODA YUUICHI
IPC: G02B7/00
Filed: 1977-12-27
Abstract: PURPOSE:To perform centering of optical fibers readily with high reliability by fixing the optical fiber placed in the bottom of a V-groove with bar form or cord form objects through the slits provided at a right angle to the V-groove. CONSTITUTION:Slits 8 are cut at a right angle to a V-groove 11 in the longitudinal direction to a base 2 which has the groove 11. A revolving shaft 6 is rotatably mounted to the bearing 7 at the top of the base 2. The shaft 6 is rotated upward, creating a large space between the keep bars 5 like piano wires mounted in the same positions as those of the slits 8 to the shaft 6 and the base 2. Next, an optical fiber 1 is put in this space and the bars are shifted downward, then the fiber 1 is evenly forced to the groove 11 of the base 2 by the bars 5. Since the bars 5 are hampered of their movement by the fiber 1, it turns out that they force the fiber 1 to the groove 11 with their bending and the repulsive force thereof. Since the groove 11 is accurately machined, the fiber 1 is always fixed in a fixed position.

Title: Telephone exchange
Inventor: CHIGA EMI
IPC: H04M3/42
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To optionally set a priority transfer function by selecting a 1st or 2nd incoming call transfer function according to the content of a table for transfer priority information setting as to which to give priority between the 1st and 2nd incoming call transfer functions stored in a rewritable memory, when an incoming call is received. SOLUTION: When an extension incoming call is received, a terminal to be called decides which between individual transfer and system transfer is preferential by referring to transfer destination priority information, and when the system transfer is decided as preferential, the terminal makes an incoming call to the terminal of a transfer destination corresponding to the extension incoming call of the system transfer. When the individual transfer is decided as preferential, whether or not individual transfer destination setting exists is checked, the incoming call is made to the transfer destination in the case the called person is in the middle of communication.  A user can select priority between an individual transfer function, that allows the user to change the transfer destinations of a call and a system transfer function capable of selecting a transfer destination according to the type of the call, so that an incoming call transfer function having a high degree of freedom can be realized.

Title: Multilayered hologram image forming lens
Inventor: ICHIKAWA NOBUHIKO
IPC: G03H1/02
Filed: 1991-06-28
Abstract: PURPOSE:To facilitate recording and generation by arranging plural holograms instead of one hologram and reducing the angle of diffraction of each hologram and increasing the interference pitch of holograms. CONSTITUTION:Light which carries information of in object point is stepwise diffracted by plural hologram lenses, and this diffracted light is finally led to an image point to form an image. That is, this optical system is the erect image forming system where the image of an object point 0 is formed at an intermediate image point F and the image of this point F is finally formed at an image point I as a second object point. Respective image forming systems consist of two holograms H1 and H3 and holograms H4 and H2. and the hologram H3 (H4) reduces the angle of light diffracted by the hologram H1 (h2). That is, angles of diffraction of optical paths beta and gamma in the case of each image forming system consisting of plural holograms are smaller than that of an optical path alpha in the case of each image forming system consisting of one hologram. Consequently, the interference fringe pitch of hologram lenses constituting image forming systems is increased.

Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To emphasize resolution without sense of incongruity by correcting the signal level of a signal for resolution correction in accordance with the signal level of a video signal. SOLUTION: A control circuit 42 controls the gain of a variable gain amplifier circuit 41 in accordance with an output signal of a low-pass filter 43. The circuit 41 amplifies a high pass component extracted from a signal level of an output signal of the filter 43 with set gain by a bandpass filter 2. An amplitude limitation circuit 3 performs amplitude limitation of the amplified high pass component and outputs signal for resolution correction. An adder 4 adds the signal for resolution correction to the original luminance signal Y1. An enhancement circuit 40 varies the signal level of the signal for resolution correction in accordance with the signal level of a luminance signal so as to correspond to nonlinear characteristic of a cathode-ray tube and varies the correction quantity of resolution. That is, the correction quantity of resolution is reduced more at a part, which has a high signal level of a luminance signal and consists of parts where an image is bright, than at a part which has a low signal level.

Title: Sound signal transmitter
Inventor: SAITO MUNEHIRO
IPC: H04M1/60
Filed: 1985-07-18
Abstract: PURPOSE:To amplify optionally and transmit a sound signal and to suppress a loop gain below 0 by providing hybrid circuits to signal transmission lines, providing a signal attenuating circuit and an amplifying circuit to those two signal transmission lines between those circuits, and controlling the quantity of attenuation according to sound signals on both transmission lines. CONSTITUTION:Input sound signals from input/output terminals (a) and (b) are inputted to a comparator 11 and compared with each other. While the sound signal is inputted from the terminal (b), the output of the comparator 11 is 'H' and the attenuation quantity of a circuit 10 decreases, controlling the attenuation quantity of a circuit 9 to a larger value. Therefore, said signal is amplified by an amplifying circuit 4 sufficiently and the output is hardly inputted to an amplifying circuit 3. When the sound signal is inputted from the terminal (a), the output of the comparator 11 is 'L' and the attenuation quantities of the circuits 10 and 9 are controlled reversely, so said result is obtained. A speech head detecting circuit 12 detects the absence of an input signal and increases the attenuation quantity of the circuit 10 to switch the output of the comparator 11 to 'L' speedily, thereby switching the input signal smoothly.

Title: Device and method for processing optical information
Inventor: SOGO KOJI
IPC: G11B7/005
Filed: 1991-06-04
Abstract: PURPOSE:To surely reproduce data by providing a means to cut binarized regenerative data signals when the amplitude of a signal corresponding to the quantity of light reflected from a medium is lowered less than a prescribed value. CONSTITUTION:When a control signal supplied from a system controller to a NOR circuit 129 is at an L level and a reflectance signal is made lower than the threshold level of a comparator 12 for signal cut by dust on an optical card, the output of the comparator 120 is turned from the L level to an H level. Therefore, this output at the H level is inverted at a NOT circuit 128, and the output at the L level is supplied to the NOR circuit 129. A gate signal for signal cut outputted from the circuit 129 is turned to the L level, and no pit detection signal is outputted from an AND circuit 130. Therefore, when the signal corresponding to the quantity of reflected light is recovered, out-of- synchronism is hardly generated, and the data can be reproduced without fail.
