Title: Light receiver
Inventor: KUMAI TAKEO
IPC: H04B10/07
Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To reduce the distortions of a QAM transmission band, which occur by means of the AM modulation signal of a light receiver receiving AM/QAM modulation signals. SOLUTION: The plural AM modulation signals of a low band and the plural QAM modulation signals of a high band are frequency-multiplexed. Transmitted light signals are converted into electric signals in a light-receiving element 1 and are amplified in an amplifier 2 and a gain variable amplifier 3. The gains of the gain variable amplifier are controlled so that outputs become constant with the output signal of a branching unit 4 and the operation of a gain control circuit 6. The light-receiving element is connected to a low pass filter 7 (LPF). Only the AM modulation signal of the low band is taken out and it is amplified in the amplifier 8. Only distortion occurring in a QAM transmission band among distortions occurred by amplifying the AM modulation signal by a high pass filter 9 (HPS).  The distortions which are taken out are converted into opposite phases at the same amplitude as the distortion occurring in the QAM transmission band by an amplitude/phase adjustment circuit 10. The distortions are synthesized by a synthesizer 5 and therefore the distortions are reduced.

Title: Driving device for precision mechanical equipment
Inventor: UZUKA MITSUO
IPC: H02P7/00
Filed: 1993-02-15
Abstract: PURPOSE:To obtain a desired feed accuracy by controlling a driving force of a main driving means based on a positional deviation and by making a bias force smaller than the driving force of the main driving means work on a movable body. CONSTITUTION:When a movable body which moves to a target position reaches a region A of a positional deviation 0 pulse, main amplifier circuits for driving (MA) 21U, 21V, 21W stops supplying main driving force to main driving coils 14U0, 14V0, 14W0 but amplifier circuits for bias driving 22U, 22V, 22W do not stop supplying bias driving current to coils for bias driving 15U0, 15V0, 15W0. Therefore, a bias force in a fixed direction works on the movable body. The movable body is likely to be pushed out from the region A. However once the movable body gets into a region C of a positional deviation + or - pulse, MAs 21U, 21V, 21W supply main driving force to the main driving coils 14U0, 14V0, 14W0 based on a main driving current controlling signal sent out from an A/D converter 25. Therefore, the movable body is pushed back to the region A again.

Title: Optical fiber tape
Inventor: YAMAMURA TETSUYA
IPC: C08G63/60
Filed: 1987-03-02
Abstract: PURPOSE:To obtain the title optical fiber tape capable of easily separating optical fiber strands and having excellent practical usability by imparting a specified Young's modulus in the lengthwise direction to the coated layer consisting of LCP having a specified group in the coating material of the optical fiber tape. CONSTITUTION:The thermotropic liq. crystal polymer (LCP) is the aromatic polyester contg. 10-30mol.% A group and 10-30mol.% B group, where the A group and the B group are equivalent, and 40-80mol.% C group. The groups A, B, and C are respectively expressed by the formulas. The LCP forms an anisotropic melt layer at 240-320 deg.C, and the Young's modulus in the lengthwise direction of the layer coated on the optical fiber is adjusted to >=7GPa. The intrinsic viscosity of LCP is preferably controlled to >=0.3. Since the LCP is oriented in the specified direction in the LCP coated layer, the strength of the tape in the lengthwise direction is increased, and conversely the strength in the direction orthogonal to the lengthwise direction is decreased. As a result, the optical fiber strands can be easily separated.

IPC: B41M3/12
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To raise a visual effect by forming a predetermined pattern layer on the alignment of transparent balls in use of a beads sheet with minute transparent balls closely adhered onto the entire surface of a base sheet, interposing a clear layer and a glossy layer being thicker than the pattern layer, and further forming a white layer and an adhesion layer being substantially equal to a plane shape of the entire label. SOLUTION: The surface of a transfer sheet is brought into contact with the surface of a colored material 12 to be transferred to then be heated and compressed at 160 deg.C for 10sec. After that, a base sheet 2 is separated from the colored material 12 to be transferred, a label pattern can be transferred. The transfer label has a pattern layer 7 and a clear layer 4 existing at the lower side of a row 6 of reflective transparent balls. A part of light from a luminous source is reflected at the row 6 of transparent balls on the label surface, and the remaining light permeated through the row 6 of transparent spheres is also reflected at the pattern layer 7 or the white layer 11 so as to become reflective light.  In this instance, light passed through the row 6 of transparent balls is led to random reflection on the clear layer 4 and glossy layer 8 positioned rearward thereof, as a result, it does not come back at all as reflective light.

Title: Self-healing fault recovering method
Inventor: SAITO HIROYUKI
IPC: H04L45/247
Filed: 1995-03-07
Abstract: PURPOSE: To realize a self-healing fault recovering method in which a recovery factor is improved as compared with a conventional method and each node has no necessity of having a large data base. CONSTITUTION: By a search phase 11, a detour candidate route and the reserve resources amount which can be applied in the route are searched and investigated and they are transmitted to a chooser. By a response phase 12, the route requesting the securing and resources amount are transmitted from the chooser to a sender. By a securing phase 13, the resources amount of the transmitted route is secured. By a confirmation phase 14, the secured route is transmitted to the sender and the route is switched to a detour route. Thus, because the search of the route and the securing of resources are separated, the securing of useless resources is eliminated. Because the route requesting the securing and resources amount are transmitted by a necessary number by the response phase 12, a path can be recovered by plural detour circuits.
