Title: Automatic control method for control constant of pid controller
Inventor: EBISU KOJI
IPC: G05B13/00
Filed: 1986-06-20
Abstract: PURPOSE:To attain the automatic control of a control constant without oscillating a control system by inhibiting the change of the control constant of a PID controller in case the angle frequency changes for each vibration cycle. CONSTITUTION:The optimum control constant of a PID controller is obtained from the attenuation constant and the angle frequency of vibrations. Then the change of the control constant of the PID controller is inhibited in case the angle frequency changes for each vibration cycle. In the case of noises, the frequency components are distributed over a wide area and therefore the angle frequency changes for each cycle. As a result, the noises are decided and no change is given to the control constant in case the angle frequency changes for each cycle. Thus it is possible to avoid deterioration of the controllability caused by the noises.

Title: System for receiving monitoring control signal for direct light amplifier
Inventor: ASAHI KOJI
IPC: H04B10/077
Filed: 1993-05-26
Abstract: PURPOSE:To send a main signal with a monitoring control signal suppressed to a reception circuit which reproduces the main signal and to accept and reproduce the monitoring control signal. CONSTITUTION:A light signal inputted and outputted from an Er-added fiber 3 is amplified as the light. The output light amplified by the Er-added fiber 3 is monitored by a pin photodiode 5 and a current/voltage conversion circuit 6 and the monitored voltage is compared with a reference voltage 7 by an arithmetic amplifier 8. The comparison output is fed back through a low-pass filter 9 and an exciting laser diode driving circuit 10 to a semiconductor laser diode 11 for excitation. Thus, the excitation level of the output light of the light amplifier is controlled to be kept constant and the monitoring control signal is extracted from the signal comparing a signal where one part of the output light is branched to control the output light and the reference voltage.

Abstract: PROBLEM TO BE SOLVED: To secure the linear reciprocating drive of a voice coil, to avoid a rolling phenomenon or the like and to improve the performance of a speaker by providing a projection part for positioning for joining the inner diameter part of a damper or/and a diaphragm to the outer peripheral surface of a coil bobbin. SOLUTION: The inner diameter part 14a of the diaphragm 14 and the inner diameter part 15a of the damper 15 are adhered to the coil bobbin outer peripheral surface 3a of the voice coil 1. At is point, since the inner diameter part 15a is positioned to the coil bobbin outer peripheral surface 3a by the protrusion 4, it is surely adhered to a prescribed position without being lowered to a lower part. Also, the inner diameter part 15a of the damper 15 is joined in the state of being inclined to the coil bobbin outer peripheral surface 3a. In such a manner, by joining the inner diameter part 15a of the damper 15 to the prescribed position of the coil bobbin in a horizontal state without being inclined or the like, the linear reciprocating motion of the voice coil 1 is secured.  Also, a coil part 2 is not brought into contact with a magnetic circuit part 11 and thus, abnormal sound accompanying contact is not generated.

Title: Liquid crystal high-polymer coated optical fiber core
Inventor: TAKEUCHI YOSHIAKI
IPC: G02B6/44
Filed: 1986-06-24
Abstract: PURPOSE:To obtain an optical fiber core which has high strength, is free from an increase in the transmission loss by a temp. change and has excellent refractiveness by specifying the degree of orientation at the abritrary point in the diametral direction of a coating layer to the value within a prescribed range. CONSTITUTION:Rods which are uniform in the diametral direction are manufactured of, for example, a copolymer consisting of 50mol% PET and 50mol% POB, then the relations between the elongation at rupture and the degree of orientation are measured. According to the results of such measurement, the elongation at rupture is at constant % or above and the coefft. of linear expansion can be simultaneously decreased to a certain ratio or below if the orientation in the diametral direction in the coating of the optical fiber is uniform and the degree of orientation is so controlled as to attain the value of such prescribed range as, for example, >=0.5 and <=0.75. The coating layer having a high modulus of elasticity and low coefft. of linear expansion is obtainable by controlling the average value of the degree of orientation distribution in the diametral direction of the coating layer to, for example, >=0.5 and the resilience of the coating layer is simultaneously assured by decreasing the max. value of the degree of orientation to, for example, <=0.75, from the above-mentioned results.

Title: Desk lamp
Inventor: YASUHARA KATSU

Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To minimize dispersion in illuminance distribution and make it difficult to cause a glare by mounting an opalescent translucent cover on an emitting opening part. SOLUTION: In this desk lamp, an opalescent plate translucent cover 40 is mounted on an emitting opening part 20 formed on the lower surface of a lamp body 15 for illuminating a desk upper surface 2. Since the translucent cover 40 transmits the direct light of a lamp 23 mounted within the lamp body 15 to illuminate the desk surface 2, the desk surface 2 can be uniformly illuminated. When the emitting angle of the lamp body 15 is set upward, the translucent cover 40 transmits the direct light from the lamp 23, whereby the glare can be suppressed even if it enters the eyes. When a one having a concave lens-like sectional form is used as the translucent cover 40, the light of the lamp 23 is diffused down ward substantially in inverted truncated chevron after transmitted by the translucent cover 40 to brightly illuminate both this side and deep side of the desk upper surface 2.
