Title: Method for heating and clarifying porous preform for optical fiber
Inventor: TSUCHIYA ICHIRO
IPC: G02B6/00
Filed: 1991-12-16
Abstract: PURPOSE:To provide a process for stably heating and clarifying a porous preform of optical fiber over a long period. CONSTITUTION:A porous preform for optical fiber is heated and clarified in a vacuum furnace having a furnace core tube under reduced pressure or in vacuum following a programmed temperature increasing pattern divided into the former and the latter time sections. In the 1st section, the temperature is increased in a reduced pressure atmosphere while passing a gas at least containing an inert gas through the vacuum furnace. The temperature increase in the 2nd time section is carried out in a reduced pressure atmosphere while passing a gas containing an inert gas at a flow rate lower than the flow rate in the 1st section or in a vacuum atmosphere absolutely free from the flow of gas. The process is effective for suppressing the oxidation and dissipation of carbon parts in the furnace body caused by the oxygen and water adsorbed to the porous preform for optical fiber and a gas produced by the reaction of a halogen gas with water. The life of the furnace body can be prolonged by this process.

Abstract: PURPOSE:To surely change over a filter position with a simple mechanism by timely and selectively changing over the position of a filter frame with a contact force with a fixing member when a sensor unit reaches to the vicinity of the fixing member provided at the starting point of a mechanical sliding and a turning point. CONSTITUTION:A filter frame 10 to execute a fixing arrangement with arranging plural filters 7-9 on a same plane is positioned to orthogonalize in a light path inside a sensor unit 12 constituted by a light source 5, a lens 6, an image sensor 11 and the like. When the sensor unit 12 reaches to the vicinity of fixing members 20 and 21 provided at the starting point of a mechanical sliding and a turning point, a contact force with the fixing members 20 and 21 acts as a compression to one end of a filter frame 10 inside the sensor unit 12, the position changing-over of each filter 7-9 inside the filter frame 10 is timely and selectively executed. Thus, the filter position changing-over can be executed by a simple mechanism.

Title: Receiver with gain control function
Inventor: MOTOJIMA KUNIAKI
IPC: H04B10/564
Filed: 1997-12-03
Abstract: PROBLEM TO BE SOLVED: To eliminate the received light power dependency of an output signal level of a receiver with a gain control function and to reproduce stable binary data. SOLUTION: A level detector 6 for detecting the level of preamplifier output signals S2 is provided and bias detection of a level corresponding to the optical output signals '0' of this receiver with a gain control function is performed with the above output. The level detector 6 turns a first peak detection circuit 7 to a sample mode when the output voltage of a preamplifier 2 is less than a fixed value, and turns it to a holding mode and holds detection output when it is more than the fixed value. An average value detector 14 detects the average potential of a positive phase output and an opposite phase output of a variable gain amplifier 3. A first comparator 9 amplifies difference between the output of the first peak detection circuit 7 and the output of the average value detector 14, and supplies it as an opposite phase input voltage to the variable gain amplifier 3.  Thus, difference between the output of the first peak detection circuit 7 and the output of the average value detector 14 becomes a sufficiently small value and bias of the output signals of the variable gain amplifier 3 is stabilized.

Abstract: PROBLEM TO BE SOLVED: To obtain a fog pattern providing gapless control independently of the polarization technology by providing an optical system having a uniaxial crystal optical filter with high double refraction performance placed in a path of an incident light. SOLUTION: A 1st double refraction device 41 of a fog filter 40 generates a light polarized at each of two spots. A 2nd double refraction device 45 has a plane 42 tilted by 45 deg. with respect to a 1st plane 43. A polarized beam generated by the 1st double refraction device 41 is not polarized in a coordinate system of the 2nd double refraction device 45. The thickness of two plates is the same, t1 =t2 . In this case, four spots in a detector plane 46 form a rhombus. In the case that the thickness of the two double refraction devices is not equal, that is, t1 is not equal to t2 , the four spots form a rhombus on the detector plane 46, that is, a parallelogram where length of opposed sides is equal to each other. The double refraction devices 41, 42 are made of a uniaxial crystal material with a high double refraction property such as lithium niobate.

Abstract: PROBLEM TO BE SOLVED: To repair a covered conduit at a low cost in a short term of works by filling concrete having a specified slump flow between a cylinder formed by assembling and connecting circularly worked corrugated titanium pirates so as to be smaller than the inner space of a box culvert in the extending direction of the covered conduit and the box culvert. SOLUTION: A corrugated titanium plate 1 is circularly worked, assembled within the inner empty space of a box culvert 11 by use of titanium-made bolts and rivets after removing a lining so as to be smaller than the inner space, and connected in the extending direction of a covered conduit by use of titanium-made bolts and rivets, and concrete 2 having a slump flow of 60 cm or more is filled between the formed cylinder and the box culvert 11. Although the concrete 2 filling space is a perfectly closed space, a concrete construction with satisfactory adhesion can be performed since the flowing property is sufficient when the slump flow is 60 cm or more. The thin plate surface of the light-weight titanium plate 1 excellent in corrosion resistance is made into a corrugated circular member, whereby the rigidity and shape holding property are improved, and an expensive repair can be performed in an extremely short term of works.

Title: Fitting structure for module cover of air bag device
Inventor: IKAWA TADAHIRO
IPC: B60R21/215
Filed: 1991-12-17
Abstract: PURPOSE:To surely prevent slip out of a module cover while an air bag is in operation. CONSTITUTION:A module cover 18 is fitted to an air bag in a manner of laying a leg piece portion 18a on an elected portion 16 of a retainer 10. The two are secured by means of a rivet 20 piercing through the erected portion 16 and the leg piece portion 18a. The outer surface of the leg piece portion 18a has a recessed portion top fit a head portion 20A of the rivet 20. Thus the stress applied to the leg piece portion 18a toward the slipping out direction when the module cover is uncovered is resisted also by the head portion 20A of the rivet 20 causing to positively prevent the leg piece portion from slipping out. It also has such effect as reducing the number of rivets and making the rivet diameter smaller.

Filed: 1989-12-21
Abstract: PURPOSE:To surely receive a radio wave signal regardless of fluctuation in the receiving electric field strength of a radio wave signal at a mobile station by providing a communication means installed indoors movably in a reciprocative way in an indoor radio equipment communicating between two communication means. CONSTITUTION:A base plate 24 moved attended with the drive of a motor 8 is reciprocatively moved in forward and reverse direction and the radiation position of a command radio wave signal is changed continuously in forward and reverse direction following the reciprocation. Thus, when an antenna 6 is located at midposition, the receiving electric field strength of the command radio wave signal is momentarily changed and even when a forklift 10 is stopped at a point reaching the lowermost point, the receiving electric field strength represents a change in the strength by the forward/reverse motion of the antenna 9 in an secular change. Thus, it is possible to receive a command radio wave signal with a strong electric field by the antenna 9. Moreover, when a radio wave radiates from the forklift 10, the radio wave radiating from the forklift 10 is received by a transmitter-receiver installed indoors independently of the position of the forklift 10.
