Title: Production of amorphous thin strip
Inventor: SAKINOU HARUFUMI
IPC: B22D11/01
Filed: 1978-09-25
Abstract: PURPOSE: To produce the captioned thin strip of board width having an excellent surface state, by injecting molten body into a first roll of low heat conductivity and super-quenching, then rolling in consequence with this roll and a second roll of high heat conductivity.  
     CONSTITUTION: For example, as a roll 1, ferriferous hard metal alloy, stainless steel base alloy, or Co base alloy  is used, and as roll 2, copper, silver, gold, or  alloy thereof is used. By means of this one pair of rolls 1, 2, molten body 4 injected  from a nozzle 3 is directed to the surface of the roll 1 to be super-quenched and  solidified, and then rolled by the rolls 1, 2. At this time, however, since a clearance  ΔG of about 200μ is provided between the rolls 1 and 2, the free surface made to a  thin strip by injecting to the roll 1 is immediately rolled and formed by the roll 2.  Therefore, either side of the thin strip has an excellent surface property, even as  precise as ±2μm or less.

Title: Magnetic recording medium
Inventor: ARIZAKA YUICHI
IPC: G11B5/64
Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To enable a magnetic recording medium improved in storage efficiency under bad environments, by forming a metallic anti-corrosive layer to an opposite face on a non-magnetic supporting body to a face where a magnetic layer is formed, and restricting a chemical change caused at the non-magnetic supporting body to a minimum. SOLUTION: A metallic anti-corrosive layer 3 is formed at an opposite face on a non-magnetic supporting body of a polymer film 1 to a face where a magnetic layer 2 is formed. The metallic anti-corrosive layer 3 has a thickness of 0.01-0.7 μm. A metal having low moisture permeability and gas permeability and high barrier effect is selected for the metallic anti-corrosive layer 3, so that storage efficiency under severe environments can be improved greatly. For example, a multilayered film of copper-nickel alloy, an alloy including at least one of copper and nickel, or many layers is used as the metallic anti-corrosive layer 3. The metallic anti-corrosive layer 3 improves not only mechanical characteristics owing to the material and thickness of the metal, but storage efficiency.

IPC: G01S13/88
Filed: 1981-07-31
Abstract: PURPOSE:To radiate electromagnetic waves with less transient phenomena and to improve the rosolution in the depth direction by forming the transmission waveforms to be supplied to a small sized antenna into monocyclic pulses. CONSTITUTION:When a trigger signal (a) comes to a terminal 21 repeatedly at times t1, t2..., the unipolar pulses of a pulse width tau are outputted from a generator 22, and are applied to the input 27 of a differential transformer 25. The trigger signal drives a generator 24 after it is delayed by the time taud smaller than the pulse width tau with a delaying circuit 23. The generator 24 generates the unipolar pulses of the pulse width tau and applies the same to the input 28 of the transformer 25. Thus the monocyclic pulses of the pulse width (tau+taud) as a differential signal are outputted to the output 29 of the transformer 25, and are supplied as a transmission signal to an antenna 26.

Title: Method and receiver for controlling clock phase

IPC: H04L25/40
Filed: 1988-05-19
Abstract: PURPOSE:To perform a fine adjustment and to make a circuit into integration by controlling the phase of a received clock signal by changing the frequency- phase characteristic of a receiver to receive a digital data signal and the clock signal. CONSTITUTION:Assuming that a filter circuit F is provided with a flat gain characteristic and a linear phase characteristic up to a frequency f1 as an amplifier characteristic, the data signal can be transmitted in a correct waveform without generating overshoot and phase jitter in an area up to the frequency f1. Meanwhile, in the area exceeding the frequency f1, the phase characteristic can be changed freely by the filter circuit F, and the constant of the filter circuit can be adjusted even in a clock frequency f2 so as to fit in a prescribed phase. It is of course that different frequency characteristics can be attached on amplifiers A1 and A2, respectively, and in that case, since the phase can be changed by changing the constant of the filter circuit, the phase of a clock can be controlled.

When the cooking is completed and moisture of the material to be cooked is evaporated, temperature of the heater 12 rapidly rises.  When the temperature becomes higher than the characteristic temperature, the electrical resistibility rapidly increases to reduce heating value to prevent scorching or overheating.

Title: Method for preventing increase of current limit loss of inverter
Inventor: YONEZAWA HIROYUKI
IPC: H02P27/06
Filed: 1994-06-02
Abstract: PURPOSE:To prevent the switching of each semiconductor switching element in the main circuit of an inverter from increasing by setting the switching frequency of each switching element at the time of output interrupting operation of the inverter lower than that during steady operation. CONSTITUTION:When an inverter for driving an induction motor with a load torque tauo at the time of output interrupting operation is operating at a switching frequency fc1 to produce an output current iu having peak value Io, the load torque increases abruptly from tauo to rhoL. Consequently, the output current also increases abruptly and whenthe peak value thereof reaches a limit value IL, the switching frequency is lowered to fc2 which is a fraction of the switching frequency c1 under normal operating state. This constitution prevents the switching loss of each semiconductor switching element in the main circuit of an inverter from increasing.
