Title: Foamed aromatic polyester resin and its production
Inventor: MOMOSE YOSHIAKI
IPC: C08J9/12
Filed: 1995-02-24
Abstract: PURPOSE: To produce a foamed material having uniform and fine texture, high expansion ratio and closed cell ratio and excellent heat-insulation, cushioning property and moldability and useful for food container, packaging material, etc., by using a specific aromatic polyester resin as a base resin. CONSTITUTION: This foamed material is produced by using a base resin consisting of an aromatic polyester resin (A) having a half-crystallization time of >=60min at the temperature corresponding to 1.25 times the glass transition temperature (in terms of absolute temperature). The foamed material is obtained e.g. by melting 100 pts.wt. of the component A with one or more extruders, mixing the molded resin with 1-20 pts.wt. of a foaming agent such as carbon dioxide gas and extruding the mixture into a low-pressure atmosphere at a die-tip resin temperature of <=200 deg.C to effect the expansion of the resin.

Title: Optical disk drive
Inventor: YAMANAKA YUTAKA
IPC: G11B7/1353
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To provide an optical disk drive which enables proper focus adjustment on an optical disk by reducing or eliminating the offset of the defocusing quantity in a groove part and a land part. SOLUTION: A relation of 0.8<λ(Tp.NA)<1.1 is set among the wavelength λof laser light, the numerical aperture NA of an objective lens for converging the laser light in a fine spot on the optical disk and the pitch size Tp of a groove part as a recording track of the optical disk. Further, a relation of (f<2> /F<2> ).L<8 (μm) is set among the focal length (f) of the objective lens, the focal length F of a convergence optical system for obtaining a defocusing quantity and the interval L between two focuses due to astigmatism on an optical axis and thereby, the defocusing quantity can be set to or nearly to zero. Thus, the parameters of the optical disk drive are limited to the specific relations and thus, the offset of the defocusing quantity on respective recording tracks of the groove part and land part is suppressed to realize high-precision focus adjustment.

Title: Head positioning method
Inventor: HAMADA TOSHIHIKO
IPC: G11B21/10
Filed: 1986-03-19
Abstract: PURPOSE:To simplify the constitution of a device by knowing the quantity of correction of a head position from a comparison output obtain in binary notation. CONSTITUTION:When a head 3 is shifted in plural stages, the position relations between the 1st and the 2nd position signals and the head 3 change, so the 1st and the 2nd read signal vary in level to cause the inversion of the comparison output. Namely, when the head 3 is positioned precisely or nearly in the center of a track T, the comparison output is inverted. The quantity of correction is therefore known from the relation between the position of the head 3 at the time of this inversion and the position of the head 3 when no correction is made. The comparison output is 1-bit data consisting of the 1st or 2nd voltage level, so this comparison output is used to simplify the constitution of a circuit which generates a position correction signal.

Title: Measuring method and device for antigen- antibody reaction
Inventor: TSUJI YASUHIRO
IPC: G01N21/49
Filed: 1981-04-24
Abstract: PURPOSE: To correlate an antigen, an antibody and a hapten quantity with each other, by a method wherein, in case an agglomeration reaction is analyzed by a light beat method, a scattering light strength signal, originating from an agglomerated 1μmp, fromed resulting from agglomeration of an unsoluble carrier particle or from an agglomeration checking reaction, is selectively detected.

After scattering light from the scattering cell 3 is converted into an electric signal by a light detector 6 through slits 4 and 5, it is sent to a frequency band selecting filter 11 via a pre-amplifier 7. A squaring device 12 restores a strength spectrum output, outputted in a square root by the filter 11,  to its original strength spectrum, and the output is recorded by a recorder 10.  The device can measure a peculiar shift indicated by a scattering light spectrum in case reaction varies corresponding to an antigen, and antibody in an  object to be measured, or a hapten quantity, and this computes the degree of  agglomeration and permits the high-precise and high-sensitive analysis of the  antigen, the antibody, or the hapten quantity.

Abstract: PURPOSE:To facilitate control by recording the write number of data in the byte of a specified area corresponding to respective tracks and updating the number every time writing is executed. CONSTITUTION:After the instruction of write in a specified track is given from a host system 10, the data of the write frequency number is generated on the corresponding byte every track of the specified sector of the specified track by a track write counter VFO/SYNC generator 5, and a control signal for writing the data in the specified byte is generated by a write gate select controller 7 and a write gate generator 8. A write gate signal from the generator 8 records the write frequency number on the specified byte area corresponding to the respective tracks.

Title: Driving power transmission structure
Inventor: TAKADA KENJI
IPC: F16H35/10
Filed: 1995-03-22
Abstract: PURPOSE: To prevent the damage of a driving system by preventing additional load from acting on each part of the driving system even in the case of the occurrence of discrepancy to obstruct the drive of a driven section. CONSTITUTION: Thrust force, namely force moving in a direction shown by an arrow B, acts on a movable worm gear 82 under a load. When the thrust force becomes larger than the energizing force of a compression coil spring, the movable worm gear 82 rotatably moves in the direction shown by the arrow B against the energizing force of the compression coil spring 88. Since a pin 86 is separated from a groove 82c by the above movement, the rotating power of a rotary shaft 84 is not transmitted to the movable worm gear 82, and consequently the driving power is not transmitted to a driving system on the downstream side of the movable worm gear 82. Thus the occurrence of the damage of the gear such as tooth chipping or the like caused by a load acting on each gear in the case of jamming can be prevented.

Abstract: PURPOSE:To reduce the power consumption without exerting substantially an influence on an inversion operation of an inverter by connecting in common a gate of a first MOS transistor and a gate of a fourth MOS transistor, and connecting in common a gate of a second transistor and a gate of a third MOS transistor concerned. CONSTITUTION:An absolute value of a threshold Vth12 of a transistor TP12 is selected so as become larger than an absolute value of a threshold Vth11 of a transistor TP11. Also, an absolute value of a threshold Vth12 of a transistor TN12 is selected so as to become larger than an absolute value of a threshold Vth11 of a transistor TN11. Therefore, when a voltage phi1 rises, the transistor TP12 becomes OFF in an early state, and when the voltage phi1 drops, the transistor TN12 becomes OFF in an early state, therefore, the time when a through- current flows through an inverter is shortened or can be eliminated.
