Title: Automatic gain control circuit
Inventor: TATSUMI KENICHI
IPC: H03G3/30
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To effectively suppress an excessive amplitude part of even a fast rising input signal and prevent distortion such as a signal clip of an amplifying circuit from being generated by delaying the input signal in timing with a control voltage. SOLUTION: The detection output of a full-wave DC detecting circuit 3 is led to a voltage control converting circuit 4 as a following stage and converted into a control voltage E4. The conversion to the control voltage E4 is performed by using a voltage, set in consideration of saturation characteristics of the output part of the amplifying circuit 5 of an amplifier to be applied with the input signal E1, as a threshold value Es and performing time delay so as to time the full-waveform shaped detection output E3 to the peak part of the a delay signal E2. The control voltage E4 is applied to an automatic gain control amplifier 2 and the input signal E1 has its amplitude suppressed by the automatic gain control amplifier 2 having its amplification degree controlled at its excessive amplitude part to evade the signal clip at the output part of the amplifying circuit 5.

Title: Field effect device and method and structure for operating it
Inventor: KUROSAWA ITARU
IPC: H01L21/8238
Filed: 1995-12-21
Abstract: PROBLEM TO BE SOLVED: To improve the carrier mobility in a carrier running area by forming the area of an intrinsic semiconductor. SOLUTION: A bulk semiconductor substrate 11 forming a channel forming area between a source 12 and drain 13 is not composed of an extrinsic semiconductor substrate, but an intrinsic semiconductor substrate 11. The intrinsic semiconductor includes not only literal intrinsic semiconductors, but also such a semiconductor that can freeze out carriers at a very low temperature, for example, a semiconductor substrate containing an impurity at a concentration N0 of <10<14> pieces/cm<3> while the substrate shows a p- or n-type trend. Therefore, the carrier mobility in the substrate 11 and, in its turn, the operating speed of a field effect device can be improved to extremely high levels. In addition, many elements can be mounted on the same substrate 11 or in the intrinsic semiconductor layer area at a high degree of integration without requiring any lateral separating area.

Title: Magnetic recording medium
Inventor: KAMINAKA HIROYUKI
IPC: C09D127/06
Filed: 1988-12-29
Abstract: PURPOSE:To improve traveling property without degrading electromagnetic conversion characteristics by incorporating metal fine powder of complete sphere particles into a magnetic layer. CONSTITUTION:The metal fine powder is a gray fine powder of complete sphere particles with 0.1 - 1.5mum particle size comprising aluminum, zinc, nickel, manganese, or alloys of these. The metal powder of sphere particles can be obtained by dropping molten metal on a rotating disk or roller in a chamber filled with inert gas so that the splashed molten metal condensates due to surface tension. These sphere metalfine particles partialy change to an amorphous state with sudden drop of temp. and become hard compared to the crystalline state of the same material. The powder particles are embedded in the magnetic layer with a part of particle is exposed from the surface layer and since the particle is complete sphere, they reduce the real contact area between the surface of the magnetic layer and a traveling post of a rotating cylinder. Thus, traveling property of the medium is significantly improved.

Abstract: PURPOSE:To reduce the generation of noise and to improve durability by providing a first gear located between main and auxiliary gears and provided with a spring to effect energization in a direction in which the phase of the auxiliary gear is delayed from that of the main gear, and a second gear engaged with the first gear, and applying crowning on the tooth trace of the former. CONSTITUTION:Crowning processing is applied on the teeth 18 of a main gear 10 on the first gear side and a tooth trace forms an contour in an arcuate or a curve shape similar thereto having a high radius. Meanwhile, no crowning processing is applied on teeth 30 on the second gear 28 side and a tooth trace is formed in the shape of a linear contour. Meanwhile, the teeth 20 of an auxiliary gear 14 juxtaposed with the main gear 10 performs operation enough for elimination of a backlash between the engaging teeth of the main gear 10 and the second gear 28, and does not attribute to torque transmission. Thereby, crowning processing may be applied or not applied. Thus, during engagement of the teeth 18 and 30 with each other, a constantly specified wide engagement area is ensured, a tooth surface bearing is reduced, durability is improved, and unevenness in an engagement position does not occur, whereby the generation of noise is reduced.

As a result, the liquid in the liquid delivery tube 1 is transferred in the direction of the arrow 9. As a result, a pumping function can be given to the liquid delivery tube 1 by making the A as the suction side and the B as the discharge side. And when the pressure-closed part is moved to the end of the discharge side, another pressure-closed part is formed also at the suction side, and the liquid in the tube 1 confined between both pressure-closed parts is pressurized until the pressure-closed part at the discharge side is opened. Consequently, a part of the confined liquid can be discharged to the discharge side by pressing the pressure-closed part at the discharge side open.
