Title: Reference voltage generating circuit of semiconductor circuit
Inventor: YAMAGUCHI KUNIHIKO
IPC: G11C11/414
Filed: 1984-03-02
Abstract: PURPOSE:To attain high speed by flowing a part of a current in a current source circuit for generating a reference voltage to a current source circuit provided in parallel with a dummy load to attain low amplitude of a cell signal. CONSTITUTION:A resistor R90 is selected identically to a value of a read current generating circuit in generating a potential VCSL and a current flowing to diodes D60, D61 flows to a current source circuit provided in parallel with a load circuit equivalent to a collector load of a memory cell. That is, the current flowing to the diodes D60, D61 is absorbed by a transistor (TR) Q70 and a resistor R71. Thus, the current flowing to the load circuit equivalent to the collector load of the memory cell is a current only decided by the resistor R90 at all times and coincident with the read current. On the other hand, in generating a potential VCSH, the current flowing to diodes D62, D63 flows similarly to a current source circuit comprising a TRQ72 and a resistor R75.

Title: Magnetic recording medium and its production
Inventor: KOBAYASHI KAZUO
IPC: G11B5/858
Filed: 1987-02-20
Abstract: PURPOSE:To prevent generation of a residual magnetic field in a nonmagnetic layer and to improve corrosion resistance by forming a nonmagnetic Cr layer on a substrate and forming a magnetic layer on the Cr layer. CONSTITUTION:For example, the substrate 1 consisting of Al, etc., is immersed in an electroless plating bath to form the nonmagnetic Cr layer 2 on the surface of the substrate 1. The magnetic layer 3 is then formed on the Cr layer 2 by, for example, an electroless plating method or sputtering method, etc. Since the Cr plating bath itself is alkaline in the forming stage of said nonmagnetic Cr layer 2, an oxide film is removed even if said film exists on the surface of the substrate 1 consisting of Al, etc. The adhesiveness of the Cr layer 2 to the substrate 1 is good and the formed Cr layer 2 has high corrosion resistance. The magnetic recording medium having the excellent adhesiveness and corrosion resistance is thereby obtd. at low cost in the simplified stage without generating the residual magnetic field in the non magnetic Cr layer 2.

Abstract: PROBLEM TO BE SOLVED: To provide a control system for a fuel gas pressure regulating valve at the time of changing-over of the fuel for a gas turbine, in which hunting in the pressure regulating valve in the low fuel rate-of-flow range is precluded. SOLUTION: A signal from a gas fuel identification signal 21 is inverted by a NOT circuit 15, is fed to a PI controller 11, and operates it in the normal operating mode, and in conformity to a fuel control signal 22, a pressure setting value is emitted by a function generator 13, and a subtractor 12 determines the difference from a gas valve differential pressure signal 23, and the PI controller 11 makes computation and emits a control signal 30 for a fuel gas pressure regulating valve.  In the low flow rate range during the fuel changing-over, a low flow rate signal 24 during the fuel changing-over is inverted by the NOT circuit 2 and actuates the PI controller 1 from a control signal line 6, and the PI controller 11 is turned out of operation by another control signal line 5, and the difference signal from the input line 4 is fed, and upon computation, a control signal 30 is emitted. Thus hunting in the pressure regulating valve 40 in the low flow rate range is precluded.

Title: Mobile radio terminal and power control method
Inventor: SAKUMA SHIGERU
IPC: H04B7/005
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption in a standby mode and in an out-of- communication area by intermittently performing ON/OFF control over the power source of a waveform equalizer in specific cycles for a certain time only when a carrier is detected, and switching a reception channel when a unique word is not detected during the ON/OFF control. SOLUTION: A UW(unique word) detection part 6 detects whether or not there is a UW from a received signal series outputted from an RF reception part 1. When no UW is detected, a sliding control part 4 turns off the power source of the waveform equalizer 5 and outputs a channel switching request signal to a channel switching control part 2. The control part 2 switches the reception channel of the RF reception part 1 to another reception channel. When a UW is detected, the sliding control part 4 is triggered in a UW detection timing of the UW detection part 6 to acquire the synchronism of a receive frame according to a frame reference timing. Then the power source of the waveform equalizer 5 is brought under the ON/OFF control in synchronism with a received frame cycle.
