Title: Fm stereo receiver
Inventor: ARITA HISASHI
IPC: H04B1/16
Filed: 1980-10-20
Abstract: PURPOSE:To reduce the multi-path distortion, by providing a switching means which switches time constant of a low pass filter constituting a PLL circuit according to the output of a multo-path detection means. CONSTITUTION:If no multi-path exists, since no output signal is present from a multi-path detector 8, a low pass filter time constant switching circuit 9 is operated and the time constant of the low pass filter consisting a stereo demodulator 7 is not switched. Thus, in this case, normal stereo demodulating operation is made. If present, a detection signal is outputted from the multi-path detector 8 is outputted, and the low pass filter time constant switching circuit 9 is operated from the output. Thus, switching is made so that the time constant of the low pass filter constituting the stereo demodulator 7 can sufficiently be greater than normal value. Thus, the variance of phase of a pilot signal produced with the multi-path can be absorbed and the multi-path distortion can be reduced.

Filed: 1980-10-23
Abstract: PURPOSE: To prevent transformation of abrasive by heat by conducting the internally stored heat of core effectively by a method wherein the core for grinding and polishing is formed by adhesive net which is extrudingly formed by polyamide resin containing a specific rate of heat conductive particles.  
     CONSTITUTION: Core for grinding and polishing material is determined by embrittlement of the surface along to the adhesive net which is extrudingly formed by polyamide resin containing 0.1% or more of heat conductive powdery particles.  A metallic shaft is, for example, penetrated into the central aperture to determine it  as a roll type grinding and polishing material by forming the core in a doughnut  shape and piling up alternately several hundred pieces of fiber type grinding and  polishing materials with the same shape as the doughnut shape core. Grinding and  polishing process is performed in use of the grinding and polishing material constituted like that. Heat generated by internal friction is conveyed to the surface of roll  shape grinding and polishing materials those cores or conveyed to a metallic shaft  in the central part. Therefore, the internally stored heat in the core is prevented,  and transformation of the roll shape grinding and polishing materials by heat is  enabled to be prevented beforehand.

Filed: 1989-06-09
Abstract: New heparin derivatives having antithrombotic activity, also endowed with reduced hemorrhagic and anticoagulant effects, obtained by treating in a basic medium heparins of various origin, optionally in the presence of alkali metal salts and of a reducing agent. The heparin derivatives obtained through this treatment show peculiar chemico-physical characteristics, like new signals at about 53 and 54 p.p.m. in the <1><3>C-NMR spectrum and a raise of the specific rotatory power, compared to that of the starting heparins, to values between +50 DEG  to +90 DEG . Said structural modifications produce an improvement of the biological properties of the heparin, substantially keeping the antithrombotic activity while diminishing the hemorrhagic effect in vivo and the anticoagulant activity in vitro.

Abstract: PURPOSE:To execute the access processing at a high speed by executing the time mechanism access proceeding on a virtual machine as a result of subtraction with signe of a real time mechanism and a time mechanism offset. CONSTITUTION:A time mechanism (TOD) offset is set to a binary integer with a signe, and at the time of executing a time mechanism setting instruction, a reset of subtraction of the binary integer with a signe is set to the time mechanism (TOD) offset. For instance, it is assumed that the TOD offset (for virtual computer 1) = (a) (a denotes a positive binary integer), the TOD offset 2 (for virtual computer 2) = (b), the TOD offset 3 (for virtual machine 3) = (c), and the real TOD = (d). In such a state, it is assumed that the TOD offset value (TOD offset 1) on the virtual machine 2 is set to (e). In this case, by executing subtraction of the binary integer with a sign, the TOD offset 1 = (e) - (d) is obtained, and in the case of a relation of (e) < (d), (e) - (d) becomes a negative binary integer. In this case, the real TOD is not changed, and also, the TOD offset 2 and the TOD offset 3 are not changed either. In such a way, the processing can be executed at a high speed.

Abstract: PURPOSE:To improve the S/N of a servo information reading signal by winding the core winding materials for the 1st and 2nd winding areas so as to offset the external electromagnetic fields produced at both winding areas to each other. CONSTITUTION:A core winding material 14A of a core winding material 14 is wound round a data reading winding area 12 by the prescribed number of turns. At the same time, a core winding material 14B continuous to the material 14A is wound round an external electromagnetic field detecting winding area 13 by the prescribed number of turns.

That is, the induced signals of both areas 12 and 13 are synthesized so that the external electromagnetic fields are offset to each other between both areas 12 and 13. As a result, only the servo information reading signal remains at the member 14 of the area 12. Thus the S/N of the servo information reading signal is improved.
