Title: Production of magnetic recording medium
Inventor: YOSHIDA OSAMU
IPC: G11B5/85
Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To obtain a magnetic film having excellent magnetic characteristics, corrosion resistance and electromagnetic conversion characteristics by scattering carbon particles and carrying out vapor deposition in such a manner that vaporized Co particles fly in a flying region with the carbon particles and deposit with released oxygen on a supporting body to form a Co-X-O magnetic film. SOLUTION: A supporting body 3 released from a supply roll 2a is traveled along a cooling can roll 1 and wound on a winding roll 2b. A vapor deposition material 5 is housed in a crucible 4 as the vapor deposition source. The material 5 is molten by an electron beam from an electron gun 8. Carbon particles are scattered by discharging a carbon rod 9a in an arc discharging device 9 to assist the vaporized Co particles to fly in a flying region. A shielding plate 6 is used to control the incident angle so that the vaporized Co particles deposit on the supporting body 3. Further. oxygen is released from an oxygen gas supply nozzle 7 in the opposite direction to the rotating direction of the roll 1. Thus, a Co-X-O magnetic film is formed. The obtd. magnetic film has excellent magnetic characteristics, corrosion resistance and electromagnetic conversion characteristics.

Title: Tape recorder operating mechanism
Inventor: MOROZUMI TAKAHIKO
IPC: G11B15/10
Filed: 1988-09-30
Abstract: PURPOSE:To eliminate the need for a solenoid and its logic circuit in a tape recorder operating mechanism by setting the quick forwarding or rewinding state of a tape after canceling the reproducing state of the tape by disengaging a cam clock lever and trigger level from each other when an operating member is operated in the tape reproducing state. CONSTITUTION:When a high-speed tape operating member 23 is operated in the reproducing state of a tape, the quick forwarding or rewinding state of the tape is set after the tape reproducing state is canceled. Namely, when the member 23 is operated in the tape reproducing state, the tape reproducing state is canceled by disengaging a cam lock lever 2 and trigger lever 19 from each other, and then, the tape quick forwarding or rewinding state is set. Therefore, prescribed operation switching can be performed directly with a mechanical mechanism without using any solenoid and its logic circuit ad the cost of this mechanism can be reduced.

IPC: H01L21/8247
Filed: 1994-09-15
Abstract: PURPOSE: To eliminate the decline of the reversing voltage and the variation of a field by a method wherein the wear of a field oxide film is avoided. CONSTITUTION: An insulating film 9 including a silicon nitride film is formed on the surface of the field oxide film 3 of the element isolation region of a semiconductor substrate 2.

IPC: H04B10/07
Filed: 1997-09-11
Abstract: PROBLEM TO BE SOLVED: To control the power level of a control channel with high reliability regardless of fluctuation in a power level for each wavelength channel and fluctuation in each time slot by providing an optical control channel before a plurality of optical amplifiers in a link. SOLUTION: The link control by this device is realized by a feedback configuration consisting of a power tap 18, a photodetector 20 and a control circuit 22.

Thus, the control channel wavelength λc produced in this way is fed back to the link through a wavelength selective coupler 26. The power level of an optical signal fed to the optical amplifiers is maintained by controlling the power level of the control channel.

Abstract: PURPOSE:To transmit data without lowering processing capacity of a terminal other than terminals to which data are transmitted to the extent of capacity more than necessary by making each terminal receive the address of a telegram when it is detected that respective signal level is kept at a level different from a level when data are not transmitted for a specified time. CONSTITUTION:A transmission line 6 is a serial transmission line that transmits data sent from a sending circuit 1 one bit by one bit, and normally kept at a high level ''H'' when data are not transmitted. A receiving circuit 2 receives succeeding data block only when the telegram sent from the sending circuit 1 is addressed to own station, and takes out the data. A transmission line monitoring circuit 7 monitors the condition of the transmission line 6 and detects whether a telegram is transmitted to the transmission line 6 or not. That is, the transmission line monitoring circuit 7 starts clocking when the transmission line 6 changes from high level ''H'' to low level ''L'' at time t0, and reports to an interruption circuit 8 the fact that the telegram is transmitted in the transmission line 6 at a time t1 elapsed t' seconds after starting clocking.
