Inventor: ADORIAN HERARUDO KETSUPERU
IPC: G11B23/087
Filed: 1993-06-17
Abstract: PURPOSE: To reduce friction between a tape pressing felt and a magnetic tape in a magnetic tape cassette storing the magnetic tape and having an opening becoming the path of the magnetic head. CONSTITUTION: The part of the tape 23 extending along the cross wall face 9 of the cassette 1 having the magnetic head opening 17 is pressed by the magnetic head 41 with the tape pressing felt 53 while a magnetic tape device is operated. A polytetrafluoroethylene PTFE material is adhered to the tape pressing felt 53 by immersing or the like. It is desirable that the tape pressing felt 53 is constituted of synthetic fibers, polyamide fibers, for example. A reduced abrasion layer is formed into the felt by immersing the felt in polytetrafluorethylene diffused in chlorofulvorocarbon and covering the surface with a film.

Title: Electric-current lead
Inventor: SHIBUI MASANAO
IPC: H01F6/00
Filed: 1990-06-06
Abstract: PURPOSE:To obtain electric-current leads whose cooling property is good, which can operate a large electric current and whose error magnetic field is small by a method wherein an entrance side conductor and an flow-out side conductor for an electric current are formed to be helices which have been wound in two stripes. CONSTITUTION:Helices 12a, 12b which have been wound in two stripes are used; the respective helices are used as an entrance-side conductor part and an exit-side conductor part for an electric current; a cooling medium is made to flow in the radius direction of the helices; both end parts of the helices are formed to be in a double cylindrical shape to form electric-current terminal parts 10a, 10b, 11a, 11b; and one pair of electric-current leads are constituted. Since electric currents in mutually opposite directions flow to the individual helices 12 constituted as two-stripe windings in this constitution, magnetic fields generated by the individual helices are canceled mutually and a magnetic field as a whole is not generated. The electric currents are not concentrated in both end parts of the helices and can be converted into the same axis. As a result, it is possible to reduce an error magnetic field generated by the electric-current leads even in the case of a large electric current.

Abstract: PURPOSE:To enable an exhaust gas to be recirculated without using such an equipment as an exhaust gas recirculating blower or an exhaust gas heat exchanger, remove the necessity of an equipment mounting space and improve a thermal efficiency by drawing, mixing and burning the exhaust gas by the combustion air blown out from a combustion air exhaust nozzle while conducting a heat exchange between the combustion air and the exhaust gas in a heat exchanger. CONSTITUTION:The combustion air is introduced in a heat exchanger 2 with the pressure of approximately 800mmAq. The introduced air is blown out from a combustion air exhaust nozzle 4 while the temperature of the air is being raised by a heat exchange. Part of an exhaust gas drawn from an exhaust gas suction port 6 by exhaust energy, while being mixed with the combustion air, exchanges heat with the exhaust gas flowing outside via an inner tube 7 and reaches a burner 8 to be burnt. In such a combustion, the NOx reduction effect of the same degree as that of a conventional cooled exhaust gas recirculation system can be obtained and a 6-7% thermal efficiency improvement can be obtained as compared with the conventional system. Further, the problems of a mounting space, a high temperature piping or the like are solved, being advantageous in cost and equipment.

Title: Magnetic tape controller
Inventor: NAKAMURA YASUO
IPC: G11B20/10
Filed: 1981-09-16
Abstract: PURPOSE:To assure the reading of information block on a tape, by stopping the travelling of tape when no information block is detected and then continuing the reading when the IBG length is larger than the decided travelling length. CONSTITUTION:When an ID burst detection flag shows ''0'' at storage part 8, a microprogram decides that no information is recorded on the loaded tape and  gives an indication to a tape device 12 to stop the travelling of the tape. Furthermore the state information showing the nondetection of the information  block is reported to a hast device 1 through a channel interface controlling part  3. When the ID burst detection flag shows ''1'' and if the IBG length is larger  than a certain value C, the reading is continued without stopping the travelling  of the tape.

Title: Rotary machine coil
Inventor: YOSHIDA KATSUHIKO
IPC: H02K3/34
Filed: 1978-11-30
Abstract: PURPOSE: To minimize a change in length due to moisture absorption for better operation efficiency and also to prevent an occurrence of pinhole defect by using a composite insulating material for which heat-resisting synthetic paper and heat- resisting synthetic film are laminated each other for insulation between coil turns.  
     CONSTITUTION: For insulators 7, 8 to be placed between rotor coil turns 5, 6, a composite insulating material comprising, for example, sticking a heat-resisting synthetic film 12 and a heat-resisting synthetic paper 11 each other as illustrated is used. Since the heat-resisting synthetic film 12 has no hygroscopic property, a positional shift will not result from perforating beforehand a hole to work as ventilating hole 10, thus improving operation efficiency. Furthermore, a use of the heat- resisting synthetic paper 11 is effective enough to prevent an occurrence of pinhole defect regardless of thermal deterioration.

IPC: G06F13/00
Filed: 1997-06-05
Abstract: PROBLEM TO BE SOLVED: To provide the system for starting a telephone directory software by which a telephone or a telephone directory application software working on a personal computer is automatically started. SOLUTION: An application (APL) start request section 6 always monitors a serial interface of a PC 1 and checks transmission of an off-hook event from an off-hook detection section 2. The off-hook detection section 2 checks whether or not an external telephone set 4 is hooked off at any time simultaneously. When the external telephone set 4 is hooked off, the off-hook detection section 2 sends off-hook information to the PC 1 via a serial interface. In this case the APL start request section 6 discriminates it that the external telephone set 4 is hooked off and starts automatically the telephone directory application software.

Abstract: PURPOSE:To shorten a wiring distance by regarding a wiring enabled area existing among wiring inhibiting areas as the boundary of the wiring inhibiting areas, constituting a coordinate system consisting of only the wiring inhibiting areas and the boundary and determining a wiring route on the coordinate system. CONSTITUTION:The wiring enabled area Y existing among the wiring inhibiting areas W to Z is regarded as the boundary L among the areas W to Z to constitute the coordinate system consisting of only the areas W to Z and the boundary L.
