Abstract: PURPOSE:To obtain a magnetic recording medium having excellent corrosion resistance and wear resistance by forming a magnetic layer consisting essentially of Fe and contg. Co, Ni, Cr and Sb by a thin film deposition method such as vapor deposition or the like. CONSTITUTION:Vapor deposition materials 61, 62 in vessels 71, 72 for vapor deposition materials are heated by an electron beam from an electron beam generator 8 onto the surface of a base body 9 such as, for example, polyethylene terephthalate film or the like and the incident angle of vapor flow is limited to 60-90 deg. by a deposition preventive plate 11, by which a magnetic layer is formed. The magnetic layer is composed essentially of Fe in this state and is contained therein with Co, Ni, Cr and Sb so as to satisfy the relation (0<x<=0.5, 0.05<=a<=0.2, 0.01<=b<=0.15 and 0.001<=c<=0.1 and b+ c<=0.2, x, a, b, c denote respectively compsn. ratios by weight). Fe contributes to an improvement in residual density and spreadability, Ni and Cr contribute to an improvement in corrosion resistance and Sb contributes to an improvement in wear resistance. The recording medium having the excellent resistance to corrosion and wear is thus obtd. at a low cost by utilizing the above mentioned respective characteristics without decreasing the electromagnetic converting characteristic so much even if the content of Co is decreased.

Abstract: PURPOSE:To provide a marker device which outputs an accurate mark frequency. CONSTITUTION:A prescribed frequency fb is selected from the sweep signal, which is repeatedly outputted from a sweep oscillator 21, by a frequency selecting part 22, and this frequency and an oscillation frequency f0 from a local oscillation part 30 are mixed to obtain a signal having a mixed frequency fi.

Filed: 1987-09-02
Abstract: PURPOSE:To realize a printer imparting stable printing grade to a medium different in kind, by selectively altering the positional relation of two medium sensors to one suitable for the detection of tolerant skew quantity desired to be monitored. CONSTITUTION:On the basis of the size of a medium and the judgement of a medium after format printing or blank paper, a CPU 18 moves a carriage 7 to set the second medium sensor 11 at the position b1n or b2n stored in a memory 15 and, at the same time, moves a value of T1n or T2n to the working area DT on the memory 15.

Title: Current mirror circuit
Inventor: TANAKA YUTAKA
IPC: H03F3/343
Filed: 1988-08-30
Abstract: PURPOSE:To reduce the dislocation of a mirror coefficient and to obtain a multi-output by keeping a connecting point between the respective bases of a first input transistor(Tr) and a second output Tr to a high potential rather than the potential of the connecting point between a basic input Tr and a basic output Tr, whose bases are commonly connected. CONSTITUTION:When an input current I1 is supplied from a constant current source 1, the current is divided into a base current IB4 of a third Tr Q4 and a collector current IC12 of a second input TrQ12. The base current IB4 is confluent with a collector current IC4 and goes to be an emitter current IE4. Then, the current is supplied to a second connecting point C. A diode D1 is is connected in a regular direction between the second connecting point C and a first connecting point B and regular direction potential drop is generated in the diode D1. Thus, Transistors Q11, Q21, and Q31 are operated with a base voltage which is lower than that of second Tr Q12, Q22 and Q32 only for the regular direction potential drop. Thus, the Tr Q11, Q21 and Q31 can be prevented to be saturated.

CONSTITUTION:Drum cutters 22, 22 are turned via flanges 20A, 20A stuck to shafts 20, 20, respectively. Since the turning torque of a gear 52 is transmitted to the shaft 2 via the gears 54, 56, two ring cutters 26 and 26 are turned via shafts 24, 24, respectively. As a result, the drum cutters 22, 22 and ring cutters 26, 26 are turned counterclockwise (as shown by an arrow A) to excavate the ground 66 with cutter bits 28, 28. In this case the external end part 22A, 22B of the drum cutters 22, 22 are set as to excavate the ground by approximately the same width. The ground 66 may be therefore excavated in the rectangular cross-section form having approximately the same width as the lining 12.

Title: Monitoring method of fuel metering system and device therefor
Inventor: HAMMEL CHRISTOF
IPC: F02D41/22
Filed: 1999-08-02
Abstract: PROBLEM TO BE SOLVED: To meter fuel correctly by discriminating a pressure signal including error on the basis of change of the pressure signal under change of a characteristic rate which is influenced in pressure. SOLUTION: A pressure sensor 110 detects pressure in a rail 112. In this pressure sensor 110, an inspection is executed whether a sensor characteristic curvature has offset error or not. In a predetermined operating condition, a pressure signal is compared with an expected value, and the pressure signal including error is discriminated depending on the comparison. The inspection is performed in an operating condition in which fuel is completely released in the rail 112. Pressure generated in this condition is already known, and a metering member applied on pressure is controlled so as to generate pressure as small as possible. In this time, in the case where the pressure signal which is remarkably larger than the expected value is received, a device discriminates offset error.  It is thus possible to surely discriminate change of the sensor characteristic curvature, and it is also possible to meter fuel correctly.
