Abstract: PURPOSE:To obtain a highly reliable semiconductor device without making silver plating by controlling the oxide concentration and working hour in the periphery of lead frames after mounting a semiconductor pellet on the die pad of a copper-alloy lead frame by means of a resin material. CONSTITUTION:After a semiconductor pellet with an electrode formed on the surface is mounted on a copper-plated copper alloy lead frame or the die pad of the copper-alloy lead frame by means of a resin material, the pellet is heated for less than 120 seconds in the atmosphere of a nonoxidizable gas with an oxygen concentration of <=1, 000ppm so as to harden the resin material. Then the pellet is kept in the atmosphere of a reducing gas with an oxygen concentration of <=500ppm so as to reduce the oxide film formed on the surface of the lead frame when the resin material is hardened to <=20Angstrom in thickness and the electrode of the semiconductor pellet and inner lead of the lead frame are wire-bonded within 12 seconds in the atmosphere of a reducing gas with an oxygen concentration of <=3,000ppm in the vicinity of the surface of the lead frame. Therefore, a highly reliable semiconductor device can be obtained without making silver plating.

Abstract: PURPOSE:To perform precise molding, by a method wherein a molding material is molded into a predetermined shape by molds and compressed air is blown in the molds from one of them to press the molding material to the outer mold. CONSTITUTION:A jet orifice 12 is closed and molds 1, 2 are preheated by heating plates 3, 4 and a molten resin 15 is injected on the molding surface 8 of the fixed mold 2. Subsequently, when the movable mold 1 is allowed to fall, the molten resin 15 spreads over the cavity 9 and air flows out from the gap between the molds 1, 2. When the movable mold 1 is further allowed to fall, the molds are clamped to seal the cavity 9 in an airtight manner by a seal member 10 and the molten resin 15 fills the cavity 9. After this state is held for a predetermined time, the molten resin 15 begins to cure and, when the start of curing is detected by the sensor in a measuring part 17, a plug 14 is operated and the jet orifice 12 is opened to introduce compressed air into the cavity 9.

CONSTITUTION:In a cold header device, crack-detecting sensors 41, 41 are arranged in each heading stage, for example, between stages 3B and 3C and after the final stage 3E. The crack-detecting sensor 41 is composed of a coil L and a power source to supply alternating current (f) to this coil and a deformed material 10 of a material to be worked is charged into the coil L in time of a measurement. When the alternating current is conducted into the coil L, a magnetic field HP is generated and a secondary magnetic field HS appears as soon as an excess current is induced in the material. For this reason, the impedance of the coil is changed and when the terminal voltage of the coil L is checked, the change and capacity of the excess current can be known. In other words, the stock (material to be worked) containing more flaws such as cracks etc., than regular stock can be detected.

Filed: 1994-07-15
Abstract: PURPOSE:To easily input scratch information even in the noisy environment by providing the scratch information code input means of switch matrix structure for detecting both a dot input and a vector input due to finger writing onto a touch panel. CONSTITUTION:When an inspecting personnel discovers that the surface of a steel plate to be conveyed to a heat stretched inspection line is scratched, the generation of the scratch, the position of the scratch the process of scratch generation and scratch name or the like are inputted to a touch panel 10 of a scratch information code input means 1 by finger writing.

Abstract: PURPOSE:To remove a sound level gain adjusting circuit contained in a bi-directional trunk, by making a digital PAD for correcting a level difference of each circuit have together a level adjusting function for making it conform with a dynamic range of a radio channel. CONSTITUTION:A sound signal level supervising circuit 18 of an incoming or outgoing trunk 17 monitors a sound level, and when it exceeds a fixed value, its information is transmitted to a central processing unit 16 through a channel control device 15. As soon as it is known that the sound signal level exceeds a prescribed value, the unit 16 sends out a signal for operating a digital attenuator 14 corresponding to its circuit, to it through a channel control device 15. As a result, an excessive signal level is attenuated and is held in a dynamic range of a radio channel. The unit 16 executes monitoring periodically by the circuit 18, and continues the operation of the attenuator 14 until a constant interval of time elapses after confirming that the sound signal level is below a reference value. In this way, a sound output level range adjusting circuit VOGAD can be omitted.

Filed: 1985-07-24
Abstract: PURPOSE:To vary electronically the attenuation of an attenuator by using a PINDIODE so as to constitute the attenuator, providing the attenuator to a receiver input section and controlling the bias current by an AGC voltage by the detection of reception input electric field. CONSTITUTION:A reception input electric field inputted to a receiver input terminal (a) is converted into an intermediate frequency by a frequency converter 3 via a variable resistance attenuator 1 and a pre-high frequency low noise amplifier 2. The change in the received input electric field inputted to the receiver inputterminal (a) is kept to a prescribed level within the operating rang of the AGC function of a main intermediate frequency amplifie 6 and an AGC voltage signal (c) in response to the change in the reception input electric field is extracted by an AGC detection circuit 9. A controller 10 uses the level of the AGC voltage signal (c) so as to apply a bias current (d) inputted to the PINDIODE being a component of the variable resistance attenuator 1 thereby controlling the attenuator. That is, the bias current (d) inputted to the PINDIODE of the variable resistance attenuator 1 is controlled automatically by the change in the reception input electric field to give an optional attenuation to the variable resistance attenuator 1.

Title: Reproducing circuit of pcm signal
Inventor: SUGIURA YOUJI
IPC: G11B3/00
Filed: 1982-09-20
Abstract: PURPOSE:To prevent the quantizing noises for a non-sound period, by using the output of a dividing circuit for the 1st clock to control the output signal of a digital-audio converting circuit. CONSTITUTION:For a counter 4, an output QP is set at ''1'' when the value of the PCM signal corresponds to a non-sound period for a 2P<-1> period of clock DK. At the same time, the outputs of Q1-QP are initialized to ''0'' in response to a case where the non-sound period does not exist for three periods of the clock DK. An AND gate 9 obtains an AND between the inversion of the QP of a counter 4 and the clock DK and is connected to a clock input terminal CK of a D/A converting circuit 1. Therefore the circuit 1 stops the D/A conversion of the PCM signal when the QP of the counter 4 is set at ''1''. In such a way, the quantizing noises can be prevented in case a non-sound period is continued.

When all the curve surfaces and curve lines are shown by the rational expression, the solution is obtained by using the algebraic method. When the curve surface and curve line without the rational expression are contained, the solution is obtained by using the analysis method.  The obtained solution is defined by an integration expression, an intersection point and an intersection line are calculated, the central travel point of a tool is obtained and NC data is generated.
