Title: Fusion splicing device for optical fibers
Inventor: SATO KATSUO
IPC: G02B6/255
Filed: 1989-10-13
Abstract: PURPOSE:To prevent the degradation in the accuracy of alignment and the estimation of a connection loss when an ambient temp. changes by providing a feedback circuit which makes negative feedback of the output signal of an optical sensor introduced with a part of the illuminating light of an optical fiber to the driving circuit of a light emitting diode. CONSTITUTION:A part of the light from the light emitting diode 2 for illuminating the optical fiber 1 is introduced into the optical sensor 21. The output signal of the optical sensor 21 is negative-fed back to the driving circuit of the light emitting diode 2. The negative feedback control by the feedback circuit, therefore, acts and the driving energy itself of the light emitting diode 2 is changed in such a manner as to attain specified luminance when the ambient temp. changes and the output luminance of the light emitting diode 2 changes. The luminance of the light for illuminating the optical fiber emitted from the light emitting diode 2 is maintained constant in this way even if the ambient temp. changes. The accuracy of the image analysis based on the electrical signal of the images transmitted through the optical fiber is maintained in the same manner as at the time of ordinary temp.

Title: Supporting body for photosensitive material
Inventor: NAKAJIMA AKIHISA
IPC: G03C1/81
Filed: 1994-10-31
Abstract: PURPOSE: To obtain a supporting body for photosensitive material having high dimensional stability and good adhesion property with little curling tendency by coating at least one surface of a SPS film with a thermoplastic resin layer to produce the supporting body for a photosensitive material. CONSTITUTION: This supporting body consists of a film essentially comprising syndiotactic polystyrene at least one surface of which is coated with a thermoplastic resin layer. Further, the thermoplastic resin layers are obtd. by co- extruding the resin on both faces of a compsn. essentially comprising syndiotactic polystyrene and then biaxially stretching and thermally fixing the layers, or by biaxially stretching and thermally fixing a syndiotactic polystyrene film and laminating the resin on both faces of the film. In this method, the film thickness of the thermoplastic resin layer is between 0.1μm and 50μm for one surface. By this method, the shrinking force of the resin layer is relatively higher than the curling force of the SPS film when the film is rolled with the thermoplastic resin layer outside, and thereby, the supporting body is hardly curled.

Title: Digital signal receiver
Inventor: IKETANI AKIRA
IPC: H04L25/40
Filed: 1984-12-19
Abstract: PURPOSE:To decrease remarkably code errors due to noise by generating plural clocks during one clock of a digital reproducing signal, using the clock to sample the digital reproducing signal and waveform-shape and using a binary value having the most value among n sets of sample values during one bit period as the value of the said one bit period. CONSTITUTION:A clock reproducing PLL2 reproduces a clock of a frequency n.fr phase-locked to a digital reproducing signal, where fr is a frequency of the basic clock of the digital reproducing signal and the clock is fed to a sift register 1. The shift register 4 uses the clock of frequency nfr, samples sequentially n values in one clock period of the signal and transmits the result sequentially. Then the sampled and stored values are transmitted to a majority decision circuit 3. The circuit 3 outputs 0 when 0s are more in the transmitted n-sample and outputs 1 when 1s are more. Thus, n-sample is obtained during one clock of the digital reproducing signal. When the noise width during one clock is [n/2]/n clock width or below, no code error takes place.

Filed: 1993-08-27
Abstract: PURPOSE:To prevent possible gap of a needle point by a method wherein a metal needle is inserted into an insulating material heated over a test temperature and the insulating material is kept from being cooled below the test temperature after the insertion thereof. CONSTITUTION:A silver paint 3 is provided on the bottom part of a high polymer insulation sample 2 as ground electrode and a metal needle 1 is inserted into the paint. For example, the sample 2 comprising closslinking polyethylene is heated up to about 100 deg.C and the needle 1 is inserted thereinto. The condition is held at about 100 deg.C for about 10min. and then, the needle 1 is advanced by a gap generated at the point of the needle 1 making an observation with a microscope. The sample 2 is immersed into a silicone oil of about 90 deg.C and an AC voltage is applied keeping the sample 2 at about 90 deg.C to measure a tree generation voltage. This eliminates the generation of the gap thereby enabling the measuring of the tree generation voltage free from the effect of the gap.

Title: Drilling device
Inventor: YAMASHITA MASAYUKI
IPC: E21B19/086
Filed: 1997-10-02
Abstract: PROBLEM TO BE SOLVED: To improve performance by installing the flow measuring-integrating means of a pressure transmission medium to a cylinder for forwarding and retreating a rock drill and a drilling-distance computing means based on an integrated value. SOLUTION: A hydraulic fluid is flowed into the rear chamber 17b of a feed cylinder 17 by a hydraulic control valve 18, and a rock drill is moved forward through a piston 172 at the time of the execution of works. An oil gauge 15 measures the quantity of the hydraulic fluid flowed into the rear chamber 17b, and an integrating indicator 16 integrates a flow rate while dividing an integrated flow rate by the sectional area of the cylinder 17 and computes the forward distance of the piston 172, and indicates the drilling distance of the rock drill on the basis of the forward distance at that time.  When the rock drill is retreated after drilling, the hydraulic pressure of the hydraulic fluid in a front chamber 17a is increased and exceeds a reference value when the piston 172 is retreated and reaches the rear wall of the rear chamber 17b, and a pressure switch 19 is turned on and an indicating section is reset to zero in the indicator 16. Accordingly, the measurement accuracy of the drilling distance and workability can be improved, and the device can be formed simply at a low cost.
