Title: Disturbance wave eliminating receiver
Inventor: YAMAZAKI SHIGERU
IPC: H04N5/21
Filed: 1984-05-30
Abstract: PURPOSE:To eliminate the mixed disturbance wave by using an extracted disturbance wave to cancel the disturbance wave mixed into the carrier signal component of a reception modulated wave. CONSTITUTION:An IF (intermediate frequency) signal obtained through conversion of frequency is led to a carrier wave reproduction circuit 1 through an input terminal. Then the carrier wave component of the same phase as a video carrier wave given from a carrier signal component is reproduced. This reproduced carrier wave component is led to a pi/2-phase shift delay circuit 2 to produce a carrier wave component having a rectangular phase to the video carrier wave. This rectangular phase carrier wave component is supplied to a multiplier 3 and multiplied by an IF signal led from the input terminal for synchronous wave detection. The rectangular phase synchronous wave detection output thus obtained is led to a multiplier 5 via an LPF4 having a pass band corresponding to both side wave transmission bands of the TV broadcast wave. While the rectangular phase carrier wave component given from the circuit 2 is supplied to the multiplier 5 via a phase compensating circuit 6. Thus the multiplications are carried out mutually between both multipliers 5 and 8 to perform modulation of amplitude. Thus an amplitude modulated wave obtained from the disturbance wave rectangular wave phase component can be reproduced accurately.

SOLUTION: The nonwoven fabric 2 used for this slip-proof under-sheet 1 is the nonwoven fabric for which the long fiber filaments made of the synthetic resin are deposited and joined non-directionally at the high density. Then, the narrow width thread line body 3 laminated on at least one surface of the nonwoven fabric 2 is composed of the polyolefine resin whose flexible rigidity rate measured by JISK7106 is less than 100 MPa and dynamic friction coefficient is more than 0.6 and is the narrow width thread line body 3 of the width 1-4 mm. The narrow width thread line bodies 3 of the width 1-4 mm are almost parallelly arranged with the interval of 4-10 mm. The narrow width thread line body 3 absorbs the energy of a load and generates deformation by being within the range of the narrow width, and as a result, frictional resistance is increased and a slip-proof property is improved.

Title: Stamping device
Inventor: MAENO HIROYUKI
IPC: B65B61/02
Filed: 1987-05-06
Abstract: PURPOSE:To permit stamping to be performed easily and securely by providing a support which upholds a stamp, a heating means for stamping which is arranged in said support and a means to advance said support to and retreat from an object to be stamped and, at the same time, to press a stamp to the object to be stamped with a comparatively low pressure force. CONSTITUTION:A pressing means 4 is actuated to advance a support 3, thereby the tip 2a of a stamp 2 is allowed to come into contact with the surface of an object to be stamped 1. Then the surface of the object to be stamped 1 with which the stamp 2 comes into contact is thermally softened by the heat of the preheated stamp 2. When the support 3 is further permitted to advance under such a condition, the stamp 3 receives a reaction force from the object to be stamped 1, being energized to a direction where an elastic member 8 is compressed. Then the stamp 2 retreats relatively to the support 3, and the stamp 2 is allowed to press the object to be stamped 1 with the predetermined pressured force due to the elastic restoration ability of the elastic member 8. At that time, stamping needs only a comparatively low pressure force, because the surface of the object to be stamped 1 is softened. Thus the periphery of any part stamped does not sink.

Abstract: PURPOSE:To protect a diode when excessive power is inputted to the diode by providing an impedance variable element and a control circuit connected to the output of a detecting circuit, and applying the output of the control circuit to the impedance variable element. CONSTITUTION:When an input signal is normal, a voltage by which the impedance across an impedance variable element can be regarded as open is outputted in a control circuit 120, and applied to the impedance variable element 500. As a result, the impedance across impedance variable element 500 is regarded as open, namely, infinite in a radio frequency band, and a normal radio signal is inputted to a diode 300. On the other hand, when the input signal exceeds a prescribed value, a voltage by which the impedance across the impedance variable element 500 can be regarded as short-circuited is outputted in the control circuit 120, and applied to the impedance variable element 500. In such a way, a voltage exceeding the prescribed value is prevented from being applied to the diode 300.

IPC: H01L29/78
Filed: 1979-08-27
Abstract: PURPOSE:To decelerate the operation delaying speed of the MOSFET by increasing the thickness of an insulating film between a gate electrode and a semiconductor  substrate thicker than that between the gate electrode and the semiconductor layer formed on the semiconductor substrate. CONSTITUTION:The thickness of a gate oxide film 6 between the gate electrode 6 and the N type semiconductor layer 8 is increased thicker than that of the film 6 between the gate electrode 7 at the bottom of the groove 5 of the MOSFET and the P type semiconductor substrate 1. the operation delaying time of the MOSFET is the product 2C1R sec. of the input capacity 2C1F and the output impedance ROMEGA of the preceding stage. Since the thickness A of the film 6 between the electrode 7 and the layer 8 is inversely proportional to the capacity C1F, the operation delaying time of the MOSFET is inversely proportional to the thickness A. Inasmuch as the thickness B of the film 6 between the electrode 7 and the substrate 1 is determined by the scaling rule from the channel length, the operation delaying time of the MOSFET is reduced proportionally to the ratio of the thicknesses A/B. Accordingly, when the ratio of the thicknesses A/B is reduced, the operation delaying time of the MOSFET can be reduced.
