Abstract: PURPOSE:To realize high senitivity and low noise by using a semiconductor laser to a local oscillator, and providing a feedback circuit so as to keep intermediate frequency constant at all times, thereby controlling the temp. of the semiconductor laser. CONSTITUTION:The light signal applied to an input terminal 1 and the light from a local oscillator 2 using a semiconductor laser are applied by a square detector 4, by which an intermediate frequency signal 6 is obtained. One of the signal 6 is conducted to a base band reproducing and detecting circuit, and the other is conducted to a feedback circuit consisting of a mixer 8, a frequency discriminator 10, etc. The circuit 10 which controls the oscillation frequency of the local oscillator 2 so as to obtain always the same intermediate frequency controls the frequency deviated from the intermediate frequency by the signal from the feedback circuit and controls the temp. of the semiconductor laser of the local oscillator 2 thereby correcting the intermediate frequency in such a manner that it is fixed at a desired set value at all times despite the fluctuations in the input signal obtained at the input terminal 1.

Title: Abnormally-dyed yarn discriminating method for synthetic fiber
Inventor: ARANISHI YOSHITAKA
IPC: G01N21/359
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To discriminate and remove an abnormally-dyed yarn having an extremely different dye-affinity without actually dying a fiber by collating the near infrared spectrum of the fiber to be judged with a standard near infrared spectrum group measured on multiple fibers, and discriminating the abnormally-dyed yarn. SOLUTION: The near infrared rays generated by a near infrared ray generating source 4 are radiated on a fiber package 1 by a radiation section 2 and diffused and reflected on the fiber package 1 and detected by a detection section 3. The obtained near infrared spectrum is stored in a memory medium as it is, or the secondary differential process allowing the correction of a spectrum baseline is applied to it, and it is stored in the memory medium as a spectrum secondary differential value. 100 or more spectrums are preferably stored. The near infrared spectrum of a fiber to be judged is collated with a standard near infrared spectrum group stored in the memory medium in advance to judge whether the yarn is abnormally dyed or not. The secondary differential value is compared with the average value of the secondary differential values of the standard spectrums for collation.

Title: Magnetic recording and reproducing device
IPC: H04N5/782
Filed: 1992-03-13
Abstract: PURPOSE:To improve the error rate of an audio signal by changeovering corresponding relation between a head corresponding to an audio.video signal mixture track and another heads even when clogging or the like is occured in the head. CONSTITUTION:In a head selecting and deciding circuit 115, at first the error rates of reproducing heads P1-P8, especially the clogging, are detected based on error monitoring signals 118a-118d from respective channels and respective kinds of status information from a servo circuit 116. It is assumed that regenerative signals from one head have a lot of errors extreamly, although regenerative signals from another heads have a few errors at the time of servo lock state at normal reproduction. For discriminating between errors due to the clogging of a head and burst errors for a short time, only when the state that C1 error detection rate for every unit time exceeds a prescribed proportion, for example 90%, continues more than a specific time (for example 10 seconds), the reproducing head is judged to be clogged.

Title: Gas soft nitriding method
Inventor: KAWADA KAZUYOSHI
IPC: C23C8/32
Filed: 1982-04-02
Abstract: PURPOSE:To attain to increase a nitriding speed to a large extent, to reduce operation cost and to enhance safety, by adding CO2 to a gaseous soft nitriding atmosphere comprising an N2 gas, an NH3 gas and an org. solvent decomposing gas to subject a material to be treated to gaseous soft nitridation. CONSTITUTION:A CO2 gas is added to a gaseous soft nitriding atmosphere comprising an N2 gas, an NH3 gas and an org. solvent decomposing gas such as a methanol decomposing gas in an amount of 0.1-10vol%. By using this CO2 added gaseous soft nitriding atmosphere, a material to be treated is subjected to gaseous soft nitriding treatment within a temp. range of 450-650 deg.C. When the CO2 gas is added to mentioned above, CO2 is reacted with a H2 gas imparting bad influence to nitriding reaction to lower H2 partial pressure and, therefore, a nitriding speed can be accerelated.

Title: Optical focusing device
Inventor: KAWAGUCHI TAKAO
IPC: G02B6/26
Filed: 1982-04-01
Abstract: PURPOSE:To prevent the propagation loss of a light wave beam and to reduce the size and cost of an optical device, by providing an optical propagation layer which has the refractive index larger than the refractive index of a transparent substrate, has the width of an inlet optical path wider than the width of an outlet optical path and has the width varied from the inlet optical path to the outlet optical path on the transparent substrate. CONSTITUTION:A focusing device has the constant width of an outlet optical path 332, which is from 1mum to 50mum. The optical waveguide to the path 332 is constituted of from 1mum to 50mum width, and the width of an inlet optical path 331 is from 0.05mm. to 5mm.. The radius of curvature on a wall surface 334 in an optical propagation layer 33 is >=1cm near the path 332, and said layer is connected smoothly to the path 332 while the radius of curvature thereof is increased. The light wave beam which is made incident through the inlet part 331 progresses by repeating total reflection on the wall surface 334. If the inlet path is connected smoothly to the outlet path 332 while the radius of curvature is made increasingly large nearer the path 332, the light wave beam is propagated to the exit path without propagation loss. A thin film of PbTiO3 is effective as the optical propagation layer and a sapphire single crystal plate as the substrate.

Title: External character processing system
Inventor: IKEZOE YOSHIAKI
IPC: B41J5/44
Filed: 1988-03-08
Abstract: PURPOSE:To prevent the loading time for character patterns from becoming long by transferring the external character patterns from a nonvolatile memory to a character pattern memory while a Japanese word output device is in its waiting state. CONSTITUTION:When the Japanese word output device 4 detects a character code which is not registered in the character pattern memory 43, a control part 41 requests a host computer 1 to load the character pattern corresponding to the code. The host computer 1 responds to the request and the control part 41 writes the dot patterns in the character pattern memory 45 and a nonvolatile memory 42 similarly to internal character loading. Then when the output device is turned off and then on, the dot patterns are loaded in the memory 45 from the memory 42. At this time, only the internal characters are loaded and the external characters are loaded when the output device 4 waits for output data from the host computer 1. Consequently, the external characters are loaded as internal characters without increasing the loading time for the character patterns.

Title: Device for moving and guiding x-ray film cassette
Inventor: TAKASHIMA YUTAKA
IPC: G03B42/02
Filed: 1987-03-11
Abstract: PURPOSE:To correct the position of a cassette even if the cassette is diagonally inserted so that the cassette is surely moved and guided by pinching both side edges of the cassette by means of 1st and 2nd long-sized bodies disposed along the moving direction of the cassette and guiding and driving the cassette in the moving direction thereof. CONSTITUTION:The cassette 10 is inserted through an insertion port onto a flat-plate shaped guide 28 in an arrow A direction. Timing belts 40 and 70 pressed to both side edges of the cassette 10 are first parted by the max. distance and, therefore, an operator is capable of inserting the cassette 10 into an arbitrary position. A motor 74 is driven when the insertion of the cassette 10 is detected by a detector 104. The timing belt 70 is thereby driven toward the timing belt 40 while the belt presses one side edge of the cassette 10. Even if, therefore, the cassette 10 is inserted diagonally with respect to the insertion direction, the cassette 10 is corrected to a straight state between the belts 40 and 70 and the cassette is surely conveyed in the arrow A direction by the belts 40, 70.
