Title: Wiring board with leads and its manufacture and module
Inventor: NAKATANI SEIICHI
IPC: H05K1/09
Filed: 1990-02-09
Abstract: PURPOSE:To enable maintenance of junctions reliable against severe environments by fixing a part of leads on lands on the board and the other part of leads are built in the board at those weakened in adhesion with the board. CONSTITUTION:An alumina ceramic substrate 101 is printed with wiring patterns and lands for connecting bare chips IC by use of a screen printing press, dried and baked in air to form wiring patterns 106 and lands 102. This step is followed by formation of leads 103 for connecting lands 102 to a bare chip IC 105. Leads are formed from a paste of Cu thick film conductor by baking in a nitrogen atmosphere under a low-oxygen partial pressure and are weak in adhesion with the alumina substrate. On the contrary, junctions of leads and lands are secured by reaction of silver and palladium with copper and by vitreous reaction of both electrode layers.

Abstract: PURPOSE:To constitute an association memory by an extremely simple circuit constitution to perform operation of size comparison of a plurality of data and sequencing regarding the size at high speed by using inverter circuits composed of neuron MOS transistors. CONSTITUTION:This semiconductor device has inverter circuits 116, 136 composed of newlon MOS transistors 102, 103, 122, 123. Then, in these circuits, the ON-OFF states of the gates of NMOS 112, 113, 132, 133 are inverted in the process of changing VR from 0V to 5V by inputting signal voltage from an input gate 151 and Vc values at those moments are memorized by the memories in these circuits. When VINB is larger than VINA, VAOUT=5V, VBOOT=OV are memorized by flipflop and when VINA is larger than VINB, VAOUT=OV, VBOOT=5V are memorized. Thereby, the relative sizes of two values can be discriminated by reading the signals memorized by flipflop after sweeping VR from 0 to 5V.

Title: Processing apparatus of sensor signal
Inventor: SATOYAMA KENICHIRO
IPC: G01R31/06
Filed: 1989-02-13
Abstract: PURPOSE:To positively supervise a sensor by providing an oscillator which oscillates at a period corresponding to a pulse period of said sensor generating a pulse in accordance with the rotation of an object to be detected, and stopping said oscillator to generate a signal of a specific level when a sensor coil is disconnected or short-circuited. CONSTITUTION:When the rotating velocity of a rotary body such as an engine is to be detected by an electromagnetic pickup as a rotary sensor 11, a pickup coil 113 is connected to a power source through a resistor R01. The sensor 11 generates a pulse of a frequency proportional to the rotating velocity, which pulse is amplified at an operating amplifier 12 and input to an oscillating circuit 13. In this circuiting when the sensor 11 is rotated normally, an oscillating signal of a period proportional to the rotating number is obtained as an output Vout. On the other hand, when the sensor 11 is not rotated, the signal is an output Vout corresponding to an internal oscillating signal of the oscillating circuit 13. If the coil 113 is disconnected or short-circuited, the output Vout becomes high level or low level, which can be easily identified.

Title: Method of burning with small amount of nitrogen oxide product
Inventor: SUZUMOTO TOMIO
IPC: F23C7/02
Filed: 1978-03-18
Abstract: PURPOSE: To reduce NOx amount by making divergent angle of combustion air flow larger than that of fuel to suppress rapid mix and combustion of fuel and combustion air in the beginning of combustion.  
     CONSTITUTION: Since the divergent angle θ 1  of fuel injected into a furnace 3 is smaller than that θ 2  of air flow, the fuel is mixed only with a portion of combustion air to start the combustion. While the fuel F enveloped by the combustion air A is diversed and mixed therewith, the combustion proceeds to form too rich fuel area I. Next, most of fuel which are not burnt in the too rich fuel area I are mixed alternatively with the main jet A of combustion air to provide a very homogeneous mixing condition and form lean fuel area II for the completion of combustion under the lean fuel condition. In the lean fuel area II, the distribution of temperature is rendered uniform by the enclosing effect of combustion gas due to the momentum of main jet flow A of combustion air in the too rich fuel area I.

Abstract: PURPOSE:To prevent the occurrence of noise at the time of reproducing on the reception side by delaying service information data and an audio signal by a time longer than the protection time of an unused code detecting circuit and synthesizing them with the output of the unused code detecting circuit. CONSTITUTION:Inputted service information data and audio signal are delayed in a delay circuit 2 by a time longer than the protection time of an unused code detecting circuit 1 and are outputted. The unused code detecting circuit 1 outputs level '0' after a forward protection time at the time of terminating detection of an unused code and outputs level '1' after a backward protection time at the time of detecting the unused code. When output service information data and audio signal of the delay circuit 2 and the output of the unused code detecting circuit 1 are synthesized, leading parts of service information data and the audio signal are not dropped out. Thus, noise is not generated at the time of reproducing on the reception side.
