Title: Method and device for instruction prefetch control of magnetic tape device
Inventor: ISHIGURO MASAYUKI
IPC: G06F3/06
Filed: 1985-07-12
Abstract: PURPOSE:To execute all writing systems by decreasing the number of the writing system instructions in response to the detection signal existing at a position near the termination area of a magnetic tape. CONSTITUTION:For a magnetic tape device which contains a buffer BF and can prefetch instructions, the number of writing system instructions which can be stored in an insutruction buffer for each reception of a writing system command from a host controller is gradually decreased when an EWA signal showing that an instruction/data prefetching control part 3 detects a place near the termination area of a magnetic tape. Thus, the time is never prolonged for the host controller to accept the next command. This prevents the abnormality caused by an over-time state.

Title: Facsimile device
Inventor: KANAI TAKEO
IPC: H04N1/00
Filed: 1990-06-14
Abstract: PURPOSE: To command the mode (facsimile mode or telephone set mode) of the called equipment without malfunction on a calling side by selecting a picture processing section or voice processing section in accordance with the pattern of a calling signal from a communication channel and connecting the selected section to the communication channel. CONSTITUTION: A pattern (a) which commands the selection of facsimile equipment or another pattern (b) which commands the selection of a telephone set is selected at an exchange based on the designation from a calling side and transmitted. When a calling signal of either one of the patterns is inputted from a communication channel, the calling signal is compared with a prescribed pattern at an automatic call incoming section 13. When the calling signal has the same waveform as that of the pattern (a), a non-ringing incoming call signal is generated to a facsimile control section 17. When the waveform of the calling signal does not coincide with that of the pattern (a), a manual incoming call switching command signal is generated to the control section 17 and an internal telephone set 21 is commanded to generate an audible ringing signal.

Title: Lightning-proof aluminum or aluminum alloy covered steel wire
Inventor: SAMEJIMA MASAHIRO
IPC: H01B7/29
Filed: 1990-06-13
Abstract: PURPOSE:To keep sufficient strength of a steel wire, protect it from contact corrosion and fusion-breaking by a thunderbolt, and improve its lightning-proof property, by eccentrically arranging a steel core material inside a covering material made of aluminum or an aluminum alloy and making the thick part of the covering material thicker than 1.6mm. CONSTITUTION:A steel core material 1 (part for functioning of strength) is covered around with an aluminum covering material 2, cross sections of both materials are made nearly to be sectors, and the core material 1 is positioned on the small circular face side eccentrically deflected from the center of the cross section of the covering material 2. Thickness H of the large circular face side, which is defined as a fusion loss allowance, of the covering material 2 is set not less than 1.6mm. With this constitution, since the thickness H between an optional point to be struck by lightning on the surface of the large circular face side (fusion loss allowance) and the core material 1 is kept sufficiently thick as 1.6mm or more, even if it is struck by lightning, temperature rising of the core material 1 is restrained due to the large fused latent heat of aluminum, protecting the core 1 from the influence of the thunderbolt. Further, to form the fusion loss allowance of the covering material 2 by eccentrically deflecting the core material 1 can heighten an occupied cross section ratio of the core material 1 in the full cross section and its strength.
