Title: Coated optical plastic fiber
Inventor: YOSHIHARA MITSUO
IPC: G02B6/44
Filed: 1982-12-21
Abstract: PURPOSE:To enhance mechanical strength and transmission characteristics by forming a resin layer having high elastic modulus hardened with UV rays or electron beams on the surface of an optical fiber, and on this resin layer, further forming a thermoplastic resin layer high in abrasion resistance, such as polyethylene. CONSTITUTION:A thermoplastic resin layer 3, such as polyester or nylon, is molded by melt extrusion on a resin layer 2 high in elastic modulus formed on the surface of an optical fiber 1. The layer 2 contributes to prevention of both creap phenomenon and thermal damage of the fiber 1, but it becomes brittler as the tensile elastic modulus becomes higher. Since the layer 3, such as PE or nylon, is superior in abrasion resistance and surface hardness, it can avoid the problem of the layer 2 and enhances the strength of the total coating layers. As a result, rise of optical transmission loss can be avoided without causing thermal damage of the fiber 1 and transmission characteristics can be improved.

IPC: H04N5/235
Filed: 1994-09-20
Abstract: PURPOSE: To cancel a flicker component by calculating a flicker frequency from a power supply frequency of a lighting fluorescent light and an electronic shutter pulse frequency and controlling a voltage controlled amplifier based upon the result of the calculation. CONSTITUTION: A voltage controlled amplifier 3 whose gain is controlled by a voltage signal amplifies a video signal from a CCD element 1 via a video signal processing section 2 to provide an output of a video output S5. A shutter pulse generating section 7 generates an electronic shutter pulse S1 whose frequency changes based on the comparison between a video level from a detection section 4 and a reference voltage from a reference voltage section 5 to control the CCD element 1 thereby making the video level constant. A 1st arithmetic section 8 calculates a flicker frequency based on the frequency of the electronic shutter pulse S1 and a power supply frequency S2 of the lighting fluorescent light and gives the frequency to a control section 10.  A 2nd arithmetic section 9 generates an inverted signal S3 inverse to the flicker component based upon the result of the calculation, and controls the voltage controlled amplifier 3 via a D/A converter section 11.

Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To attain facilitation of inspection and maintenance and, make the most of a function picking a driving current signal of a blower and a signal and a function calculating a difference of moving average values of the driving current signal and a current signal for fixed time before and after the driving current signal for an operation control of a blower by having the functions. SOLUTION: At a normal operation, a current value becomes an almost fixed value because little blowing amount fluctuates but rapid decrease and rapid increase of the current value are repeated in a surging state in the periodical moment of about 1 second. Thus, current waveforms are different in a normal state and the surging state. By taking this feature, surging is detected. In this case, a clamp meter 7 is installed in a phase of a power source line 6 supplying power to a blower driving electric motor 5. Samplings are performed for current value signals from the clamp meter 7 with 1 to 10 Hz in a sampling circuit 8. Next, sampling values are delivered to a comparator circuit 10. The sampling values are moved and averaged in a moving and averaging circuit 9 and the value is delivered to the comparator circuit 10.

Filed: 1988-09-09
Abstract: PURPOSE:To prevent the fluctuation of the relative positions of resistors due to attachment of a detecting apparatus and to improve accuracy by attaching an intake-air-temperature detecting resistor and a flow-speed detecting resistor to the same base material. CONSTITUTION:A thin film shaped intake-air-temperature detecting resistor 2 and a flow-speed detecting resistor 3 are attached to the plate surface part of a rectangular planar base material 1. The base material 1 is a silicon substrate on which a planar insulating film comprising glass, ceramics and the like is formed. The thin films of the resistors comprising nickel, platinum or the like are attached to the base material by evaporation, baking and the like, and the resistors 2 and 3 are formed. The flow-speed detecting resistor 3 is kept at a high temperature by self-heating. A current is supplied so that the temperature difference (resistance difference) between the resistor 3 and the intake-air-temperature resistor 2 is kept constant, and a flow speed is detected. Since the relative positions of both resistors 2 and 3 are kept constant, highly accurate measurement can be performed regardless of the attaching state.
