Title: Manufacture of semiconductor device
Inventor: OZAWA KIYOSHI
IPC: H01L21/3205
Filed: 1988-07-01
Abstract: PURPOSE:To inhibit the generation of a hillock and to prevent a short-circuit by a method wherein, after Al metal films are deposited on a wafer, the wafer is put in an atmosphere of a low temperature, irradiated with prescribed heat rays from the rear side of the wafer, and annealed with the surface temperatures of the Al metal films held lower than a temperature of recrystallization. CONSTITUTION:Al films 9 are patterned on an Si substrate 8 according to a wiring pattern and after that, the substrate 8 is held by a substrate holder 7 and is put in the interior of an annealing furnace 1. Then, the Al films 9 on the substrate 8 are annealed by a CO2 laser 12. A laser beam 12a from the laser 12 is reflected by a galvanoscanner 13 and after that, is directed from the rear side of the substrate 8 through a window member 11 and goes scanning the Al films 9. At this time, the surface temperatures of the Al films 9 are simultaneously held at least 200 deg.C or lower by the flow of low-temperature gas evolved from a liquid nitrogen 4. Accordingly, the interiors only of the Al films 9 result in being heated and an Al atom transfer is inhibited in the vicinities of the surfaces of the Al films 9 after scanning with the laser beam. As a result, the growth of a hillock is inhibited to a thickness of about 1000Angstrom or thinner and a short-circuit between wiring parts can be prevented.

Inventor: MAAKU ERIOTSUTO JIYAKOBUZU
IPC: H02M1/42
Filed: 1994-06-27
Abstract: PURPOSE: To eliminate a ripple from an output signal by using a controlled harmonic oscillator having output for tracing the principal wave of an input voltage waveform, introducing two sine wave signals with phases deviated from the input sine waves, and squaring and adding the introduced sine wave signals for quickly and accurately introducing the squared value of the peak of the sine wave signals. CONSTITUTION: Integrators 101 and 102 are connected in series to each other, and a controlled harmonic oscillator is formed within an almost close feedback loop. Then, AC voltage having a nearly sine waveform is applied from an input terminal 105. As a result, the integrators 101 and 102 integrate the volt-second values of the AC voltage waveform, and output signals from the integrator 102 are sent to gain circuits 111 and 113 after addition to an AC line sine wave VAC through an adder 107, thereby controlling the time response of integrators 101 and 102. The output signals from the integrators 101 and 102 become sine waves with phases different from each other by π/2 and synchronous with the AC line sine waveform VAC. Furthermore, the output signals from the integrators 101 and 102 are squared via corresponding square circuits 115 and 117, and added to each other through the adder 119 for introducing the squared value Vpeak <2> free from a ripple.

Filed: 1980-11-27
Abstract: PURPOSE: To make the control of a weld zone sufficient and make welding abnormality easy to find by deflecting an electron beam for a short time during welding to melt the part other than the weld zone slightly, and corresponding the pulses during this deflection to the recorded welding conditions.  
     CONSTITUTION: During welding of a weld line with an electron beam welder 1, an electron beam is deflected like pulses for an extremely short time up to the position apart from the weld zone by a deflection mechanism 3. Thereby, the surface of the base metal apart from the weld zone is slightly melted. On the other hand, welding conditions are recorded in a recorder 4; at the same time, the pulses corresponding to the time when the beam is deflected are generated and these are recorded simultaneously. Thereby, the correspondence of the record of the welding conditions and the position of the actual weldment is easy to be accomplished, and since the control of the weld zone is carried out sufficiently, the reliability of the weld zone is improved.

Title: Structure of exhaust pipe
Inventor: NAKAJIMA HAJIME
IPC: F01N13/20
Filed: 1994-06-23
Abstract: PURPOSE:To prevent concentrated discharge of exhaust gas by mounting a member on the tip part of an exhaust pipe coupled to an engine and converting a jet of exhaust gas into a swirl. CONSTITUTION:An exhaust pipe 12 having an exhaust port for exhaust gas formed in such a state to protrude from the rear surface part of a counter weight 6 is provided at its interior with a function to convert a jet of exhaust gas into a swirl flow. The exhaust gas pipe 12 has an rear end part in the inner peripheral surface part of which a spiral recessed groove is formed. A rotation force is exerted on exhaust gas discharged from an engine 7 when the exhaust gas passages through the spiral recessed groove and the exhaust gas is discharged through the tip part thereof as it is revolved. In this case, since discharged gas is revolved, the gas is radially spread and dispersed by a centrifugal force. Thus, since exhaust gas is prevented from being concentratedly discharged, there is no need for an operator to pay attention to the periphery of a site and operation is practicable without anxiety.

Title: Logarithmic converter
Inventor: DEEBITSUDO II KUROUZAA
IPC: G06G7/24
Filed: 1979-12-20
Abstract: PURPOSE:To avoid the production of linear component undesirable in the output voltage, by providing the series circuit of the resistor and the logarithmic conversion element between the output terminal of the logarithmic amplifier and the reference potential point. CONSTITUTION:The operational amplifier U1 supplies the output voltage to the emitter of the feedback transistor TrQ1 and performs control so that the collector current Ic is equal to the input current Ib. Since the voltage between the emitter and base of TrQ1 is proportional to the logarithmic value of the current Ic, the voltage at the junction J1 is proportional to the logarithmic value of Ic. When the internal resistance r13 is present, the voltage at the junction J1 is changed by the linear component equal to Icr. Further, the voltage at the junction J1 produces the current IA flowing the logarithmic convertion TrQ2 and the resistor R15. If TrQ2 is ideal, the internal resistance is zero. When the resistance value R is selected so that IAR= Icr, the linear component of the logarithmic amplifier 6 is cancelled in the resistor 15. Further, IA=Ic is obtained, the linear component can be cancelled by setting the value of R so that R=r when the internal resistance of TrQ2 is zero.

Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To prevent the development of corner-welding crack without needing straight-cutting and beveling, and to obtain a box column having high toughness at HAZ(heat-affected zone) by welding a flat steel as-roll and assembling to manufacture the box column for building structure. SOLUTION: In the flat steel, since the center segregation is separated to the center side from the edge surfaces in the width direction, a segregation part exposed on a beveling surface is reduced in comparison with a straight-cut steel plate and the sensibility of the corner-welding crack is extremely lowered. It is desirable that both edge sides in the width direction of the flat steel are roll-formed into a bevel-shape for corner welding. Chemical composition of the flat steel is desirable to be the following composition by wt.%. This is composed of 0.08-0.18 C, <=0.6 Si, 0.8-1.8 Mn, <=0.015 P, <=0.008 S, 0.002-0.05 Al, 0.03-0.15 V, 0.005-0.015 N and one or two kinds among 0.1-0.7 Cu, 0.05-0.6 Ni, 0.05-0.5 Cr, 0.03-0.2 Mo, 0.005-0.04 Nb, 0.003-0.02 Ti, 0.001-0.01 Ca and 0.001-0.01 REM.

Title: Telephone device
Inventor: OSADA HIROSHI
IPC: H04M1/738
Filed: 1983-09-09
Abstract: PURPOSE:To use a public telephone line, to which a periodically polarity-inverted signal comes, to make the originating call from a general subscriber's telephone set possible, by connecting a specific additional circuit to the preceding position of the general subscriber's telephone set through the contact of a response monitor relay of magnetic latch type. CONSTITUTION:A public telephone set TEL1 and a general subscriber's telephone set TEL2 are connected to connection terminals L1 and L2 of the public telephone circuit by switching switches SW1 and SW2. When the telephone set TEL2 is hooked off and a response signal of a called subscriber comes, a response monitor relay M is operated to switch a contact (m), and a current is flowed to a light emitting diode LD. As the result, transistors TRs PT and Tr1 are made conductive to make continuation of the cell possible. When the handset is hooked on, the light emitting diode LD stops emitting light by cut-off of the current, and TRs PT and Tr1 are turned off, and therefore, loop formation due to a diode bridge is stopped, and a thyristor SCR1 is made conductive, and the relay M is released. A current in the release direction is prevented from being flowed to the relay M during call by a constant voltage diode ZD4, a capacitor C6, and the thyristor SCR1.
