Title: Manufacture of composite material having deformed reinforcing core
Inventor: KASAHARA TOSHIO
IPC: B21C23/24
Filed: 1980-06-03
Abstract: PURPOSE: To prevent a change in the relative position between a worked part of a metallic coat surface and a metallic core material to be caused by a next extrusion work, by forming a longitudinal marking line in the outer surface of a metallic coat, at manufacuturing a composite material comprising a metallic coat and a deformed reinforcing metallic core.  
     CONSTITUTION: At manufacturing a composite material 4 such as a trolley wire comprising an Al coat 2 provided with a groove 3 and a steel made core material 1, the steel made core material 1 has a deformed cross section of a long cocoon shape, and the groove 3 of the Al coat 2 is formed almost vertically to the flat plane of the steel core 1. For this purpose, first of all, a steel core 6 is threaded in a nipple 5 having a nipple hole 5a in the same shape as the cross section of the steel core 6 which is then drawn through a die 7 so as to coat the surface of the steel core 6 with an Al coat 8; hereupon, if a concave groove A is prepared in the die hole 7a, a convex line corresponding to the concave groove A is formed in the surface of the Al coat 8. Since the position of this convex marking line and the position of the steel core 6 are invariable, the position of a groove 3 to be formed in the Al coat 2 by the next extrusion work is always kept constant against the steel core 1.

Title: Quadrature modulator
Inventor: TOMARU KENYA
IPC: H04L27/20
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To allow an orthogonal modulator to cope with dispersion in components and a change over aging and to ensure high modulation accuracy by detecting an error caused in an analog circuit and adding a signal having an inverse characteristics to that of the error to the data before D/A conversion so as to relax circuit design requirements. SOLUTION: A digital quadrature demodulator 12 converts a received signal into a base band signal consisting of an I component (I') and a Q component (Q') and gives the converted signal to an error detection/compensation circuit 1. The error detection/compensation circuit 1 compensates a modulation error by using original signals I, Q and feedback signals I', Q'. that is, the error detection/compensation circuit 1 detects a DC offset and a phase error, and conducts processing to obtain an in-phase component (I') and a quadrature component (Q') resulting from adding a signal having an inverse characteristics to that of the errors to the in-phase component (I) and a quadrature component (Q).  Thus, the in-phase component (I') and the quadrature component (Q') to which the signal with the inverse characteristics is added are D/A- converted and subject to quadrature modulation so as to cancel a DC offset component of a D/A converter and a phase error component of an LO signal. As a result, only a signal component remains in a modulation wave.

Title: Cmos type current amplifier circuit
Inventor: IKEJIRI HIROAKI
IPC: H03K17/687
Filed: 1985-04-09
Abstract: PURPOSE:To suppress higher harmonic noises produced under the transient state of output signals, by commonly connecting all the gates of FETs and connecting the FETs in series by connecting the source of one FET with the drain of another, and then, changing the driving capacity of an output-stage current amplifier circuit in accordance with the weight of a load and frequencies of the output signals. CONSTITUTION:Selection of FETs is performed by turning on the turning off switches connected in parallel with the FETs. When the channel width ZN of each N.FET is previously changed and the channel width ZN is selected in accordance with loads and operating frequencies, the rising time tf of an output can be set variously and, when the channel width ZP of each P.FET is changed, the rising time tr can also be set variously. Since the rising and falling times tr and tf depend on the frequency band of an output signal, setting of the rising and falling times to various values is effective in suppressing higher harmonic noises. The 201 of the figure indicates the output waveform with a higher operating frequency and the 202 indicates the output waveform with a lower operating frequency when the set values of the rising and falling times tr and tf are changed. When a photomask for forming a wiring is switched by means of a CMOS-LSI in the manufacturing process, wirings of 114-121 are switched and FET selection can be performed.

Abstract: PURPOSE:To reduce the leakage of a digital noize and thus ensure an effective correction of distortion over an entire region of a screen, by producing an interpolation coefficient between the key points through a multiplication-type D/A converter and then calculating the degree of each distortion correction through the said converter from the degree of distortion correction of the key point read out of a storage circuit. CONSTITUTION:Both horizontal and vertical driving signals HD and VD are supplied to a memory address -k signal generating circuit 2, and both horizontal and vertical address signals are applied to a storage circuit 3 from the circuit 2. The degree of key point is stored previously in the circuit 3, and the degree a1 of a key point and degree b1 of the other key point are supplied to D/A converters 4 and 5 respectively by the address signals corresponding to the synchronous signals. In the mean time, the n signal is supplied simultaneously to a D/A converter 6 from the circuit 2, and the analog output of degree K supplied from the converter 6 is applied to a reverse amplifier 7 and the converter 5. In addition, 1-k given from the amplifier 7 is applied to the converter 5. Then the degrees a1 and b1 are multiplied by k and k-1 through the converters 4 and 5. Thus a correction of distortion is carried out over an entire region of a screen.
