Abstract: PURPOSE: In the melt spinning of high molecular weight polymer, substantially heated silicone oil is coated on the spinneret surface to prevent the polymer dripping, filament wrapping and yarn break during spinning.  
     CONSTITUTION: In the melt spinning of high molecular weight polymer, such as polyester, nylon, the surface of the spinneret is coated with a heat-resistant silicone oil that is mainly composed of polydimethylsiloxane preferably with 500W100,000cps viscosity and polymethylphenylsiloxane preferably with 100W1,000cps viscosity and heated to a temperature over the glass transition point of the silicones. The silicone oil is placed in a vessel 1 and sprayed through air-gun 2 with heater 3 at the top end to the spinneret 4 at 150°C. When the silicone used is high heat-resistant, it may be heated while stored.

Title: Magnetic recording and reproducing device
Inventor: TSUJI MASAKI
IPC: H04N9/83
Filed: 1989-03-01
Abstract: PURPOSE:To prevent color blur due to a comb line filter by selecting the output of a color signal processing device or that of a comb line filter circuit in accordance with the output of a correlation detecting device by a color signal changeover switch. CONSTITUTION:A comb line filter circuit 10 consists of a 1H delay element and an adding circuit in the case of NTSC, and the signal from a crosstalk track is cancelled by the adding circuit. Meanwhile, a delay circuit 13 consists of a delay element which has the same delay time as the delay element of the circuit 10, and therefore, a luminance signal component simultaneous with the color signal component processed in the circuit 10 is inputted to a subtracting circuit 14. Consequently, the difference signal outputted from the circuit 14 is converted to an absolute value and the level of this absolute value signal is compared with a prescribed value, and thereby, a correlation detecting circuit 15 detects correlations or non-correlations of a pattern at the timing of signal processing in the circuit 10. When no correlations are detected, a changeover switch 11 directly selects the output from a BPF 9 by a switching control signal of this detection; but when correlations are detected, the switch 11 selects the crosstalk eliminating signal from the circuit 10.

Title: Harmless solid fuel
Inventor: KOBAYASHI YOSHIHARU
IPC: C10L11/00
Filed: 1981-04-03
Abstract: PURPOSE: A harmless solid fuel reduced in an amt. of CO evolved in the early stage of combustion, which is prepd. by at least partially compounding a solid fuel such as a briquet or an oval briquet with manganese slug.  
     CONSTITUTION: A solid fuel such as an ordinary briquet or an oval briquet is compounded with 0.5W20wt% manganese slug produced as a byproduct in the preparation of potassium permanganate, and molded and dried by the usual method. In the case of an inflammable briquet or an ignitable one, 1W20wt% manganese slug is incorporated in the inflaming portion or 0.5W30wt% in the igniting portion. The manganese slug reduces the amt. of CO evolved, probably because MnO 2 , Fe 2 O 3 , Al 2 O 3 , SiO 2 , etc. in a manganese ore are oxidatively calcined together with KOH in a highly oxidative atmosphere during the preparation of potassium permanganate and then adequately hydrolyzed, so that each oxide becomes an active oxyhydroxide, which catalytically oxidizes CO and CO 2  together with part of slaked lime and KOH added in the preparation of the potassium permanganate.

Title: Dust explosion preventive device in laser processing device
Inventor: MITSUYOSHI HIRONOBU
IPC: B23K26/14
Filed: 1998-03-02
Abstract: PROBLEM TO BE SOLVED: To prevent the danger of ignition/explosion caused by the heated dust of electrostatic by spraying a gas of high oxygen density to the dust generated in a step for processing a work material such as aluminum, and promoting oxidation of the dust. SOLUTION: For example, a YAG laser beam 3 for work processing is radiated from a tip of a processing nozzle 2 of a processing head 1, and an inert assist gas 4 such as air is exhausted from the periphery of the laser beam 3 at the same time. Oxygen of a gas 8 with a high oxygen density is sprayed from plural ejection holes 7 to a work metallic dust 5 which is exhausted from the cutting processing part of a work W supporting member 6 and not oxidized fully in a comparatively little amount step, so as to fully ozidize the dust at this step. The oxidation of the dust is promoted by the processing laser light and residual-heat, and the oxidation is further promoted by the gas 8.  Therefore, in the following steps even if the dust is accumulated in a dust collecting duct and a dust collecting device to some extent, the danger of ignition/explosion caused by the origin of fire can be eliminated.

Title: Phase locked loop circuit
Inventor: YASUE NORIMI
IPC: H03L7/08
Filed: 1992-03-06
Abstract: PURPOSE:To make a PLL circuit single by constituting the PLL circuit which generates a reference clock whose oscillating efficiency is high, which is synchronized with a video signal at a high speed even when the video signal is standard or non-standard, at the time of preparing the reference clock synchronized with the inputted video signal, and supplying it to a picture processing system, in a picture processor. CONSTITUTION:A horizontal synchronizing signal 8 obtained from a synchronizing separator circuit is compared with a signal 12 frequency-divided by a frequency dividing circuit 4 by a phase comparator circuit 2, based on a reference clock signal being the output of a voltage control oscillator 3. Then, when the phase difference of the two signals is more than a constant value, a braking signal 9 outputted from a control circuit 5 is outputted as an inhibiting signal, transmitted through a gate circuit 7, and a frequency-dividing operation is stopped. When the next horizontal synchronizing signal 8 arrives, the braking signal 9 is changed to a permitting signal. As the result, the frequency-dividing circuit 4 resumes the frequency-dividing operation, and the synchronizing operation is attained.

Title: Satellite communication system and center station
Inventor: MATSUBARA NOBORU
IPC: H04B7/204
Filed: 1998-03-02
Abstract: PROBLEM TO BE SOLVED: To inexpensively inform a user in the middle of conversation of a connection request by transmitting a signal for informing the user of effect that the connection request is given when the carrier level of a specified frequency is not more than a prescribed level. SOLUTION: A user C who is to urgently communicate with a user A dials the telephone number of the user A with a special number. Thus, a connection request generated by a very small aperture terminal(VAST) station 11 is received by the monitor control reception unit of a center station 12. Upon detecting the connection request containing the special number to the monitoring control reception unit, a monitoring controller sets the frequencies of demodulators 1 and 2 and the frequency of a modulator by using the frequencies so that the levels of transmission and reception carriers allocated to the user A can be measured based on the number of an opposite party contained in the connection request. When a user B being the call opposite party of the user A does not emit sound, information is given to the user A by using the modulator to the effect that an urgent call is inputted.

Abstract: PROBLEM TO BE SOLVED: To reduce faults of an electric system of a mechanism in a device case body. SOLUTION: A coin C thrown in a coin brow-in port member 2 drives a coin sorting orbit 17, and whether the coin is authentic or not is discriminated by a coin discriminating means 18.
