Title: Battery life judging device
Inventor: MUSASHIJIMA SHINJI
IPC: H01M10/48
Filed: 1994-05-26
Abstract: PURPOSE:To easily judge the life of a battery by measuring the discharge time from the detection of a charge completion to the detection of a discharge end, when the discharge end is judged, and displaying the measured value. CONSTITUTION:When a discharge is started, a timer means 120 starts counting, and the elapsed time is displayed on a display means 125 through a display driver 122. The battery voltage Vb under discharge is monitored by the discharge end judging means 126 of a control part 14, and at a point of time when the voltage Vb is lowered to a fixed end voltage, the discharge is ended. When the discharge is ended, the discharge time from the detection of the charge completion by a charge completion detecting means 116 to the detection of the discharge end by the discharge end judging means 126 is measured. When a change-over switch 108 is closed at that time, a charger is charged, and when it is opened, the discharge is started. Thus, no higher skill is dispensed with, and the life of the battery can be easily judged.

Title: Automatic gain control device
Inventor: HOSOI OSAMU
IPC: H04N5/91
Filed: 1987-05-29
Abstract: PURPOSE:To make an input to an A/D converter constant without deteriorating the S/N of a chrominance signal by extracting only a part of a synchronizing signal subjected to FM modulation, detecting the amplitude of the part and using the detection output as a control signal of a variable amplifier. CONSTITUTION:A low frequency conversion chrominance signal is extracted from a low pass filter LPF 8, and a luminance signal subjected to FM modulation is obtained from a high pass filter HPF 9. The output of the LPF 11 is inputted to a synchronizing separator circuit 12, where a synchronizing signal is separated and the result is fed to a detection circuit 13. The detection circuit 13 detects the amplitude of the FM modulation luminance signal inputted from the HPF 9 and sends the detection output to the LPF 14 for the synchronizing signal period inputted from the synchronizing separator circuit 12. The output of the LPF 14 is converted into an analog signal by a D/A converter 7 and becomes a control signal for a variable amplifier 3. Since the amplitude of the reproducing signal is made constant independently of the content of the luminance signal, the S/N of the chrominance signal is not deteriorated.

Title: Signal detection circuit
Inventor: HORII NOBUHIRO
IPC: H03K5/00
Filed: 1989-05-29
Abstract: PURPOSE:To detect effectively a 1-bit signal at a sender side as a 1-bit signal at a receiver side even when the clock at the sender side is fast by combining an R-S FF and a D FF. CONSTITUTION:When a one-shot pulse signal rising in a timing 4 and falling in a timing 5 is inputted to a set input of an R-S FF 11, a Q output goes to an H level. Since the Q output of the FF 11 is given to a D input of the FF 12, the output of the FF 12 latches the H level at the leading of the clock B. When the Q output of the FF 12 goes to an H level, the reset input of the FF 11 connecting to the output of the FF 12 goes to an H level, the FF 11 is reset to a 0 level. The 0 level output of the FF 11 is latched at the succeeding leading of the clock B and the output of the FF 12 goes to a 0 level in a timing 23. Then the 1-bit signal of the clock A is detected effectively as a 1-bit signal of the clock B.

Abstract: PURPOSE:To prevent the erroneous output of an internally generated video signal even in the case of a failure of detection of a reproduced video signal in a video signal discriminating circuit at the time of special reproducing by always inhibiting switching to the internally generated video signal independently of the video signal discrimination output at the time of special reproducing. CONSTITUTION:When a reproduced video signal 5 is absent at the time of reproducing, a control signal 12 is outputted to select and output an internal video signal 9 generated by an internal video signal generating circuit 8. At the time of special reproducing, the output of the output control signal 12 of a video signal discriminating circuit 10 is inhibited by an output 14 of a special reproducing control signal 11. Thus, the video signal discrimination output 12 for switching between the reproduced video signal 5 and the internal video signal 9 is inhibited to prevent switching to the internal video signal 9 by the special reproducing control signal 14, thereby always outputting the reproduced video signal.

Abstract: PROBLEM TO BE SOLVED: To provide a technique which improves reliability of an MISFET comprising a gate electrode of a tungsten polycide film. SOLUTION: An n-type impurity for forming an n-type semiconductor region 7 is doped into a semiconductor substrate 1 with a gate electrode 6, comprising a WSix (tungsten polycide) film 5 and a polycrystalline silicon film 4, as a mask. Next, the semiconductor substrate 1 is cleaned using liquid which does not etch silicon oxide or silicon oxidizable liquid, and immediately after the exposed surface of the WSix film 5 is covered with a thin natural oxide film 8, heat processing at a temperature of 900 deg.C is performed on the semiconductor substrate 1 for activating the n-type impurity. This processing causes composition change in the WSix film 5, however, as the extraction of W or WSi is suppressed by the natural oxide film 8, short circuit between adjacent gate electrodes can be prevented.

Abstract: PROBLEM TO BE SOLVED: To enable continuous oscillation at a room temperature by lowering Vf of a laser element composed mainly of a nitride semiconductor, and reducing the quantity of heat to be generated by the laser element. SOLUTION: This laser element has a stripelike n-like layer, an active layer 5, and a p-type layer formed in order on the upper part of a substrate 1, and a part of the p-type layer is etched and the surface of the n-type layer is exposed, and on the surface of the p-type layer a stripelike p electrode 11 is formed.

Abstract: PURPOSE:To prevent a magnetic fluid from splashing and eliminate a problem such as contamination. CONSTITUTION:A shaft 1 is formed as a fixed side and a pole piece 11a as a rotation side. The end of the spindle 2 of the shaft 1 is chamfered all around to form a taper section 22 expanded toward an air releasing section 32. As a result, even when a liquid level at the side of the section 32 bulges outside, due to the temperature rise of the fluid 15 under continuous rotation and the subsequent expansion of the fluid 15, the expanded fluid 15 can be absorbed by the space of the section 22 of the shaft 1 formed as the fixed side. In addition, the fluid 15 is not splashed toward the pole piece 11a at the outside, due to a centrifugal force. According to this construction, a problem such as contamination due to the splash of the fluid 15 does not occur.
