Patent JP-H07221106-A (JP)
Title: Electronic circuit device
Inventor: SAKATA TOMOAKI
IPC: H01L21/60
Filed: 1994-02-08
Abstract: PURPOSE:To provide the structure of an electronic circuit device which allows the electronic circuit device, which has a plurality of bump contacts for electric connection with a group of terminal electrodes formed on a substrate, to be connected to the substrate economically and with a high connection reliability. CONSTITUTION:On one face of an electronic circuit device where bump contacts 2 are formed, bumps 3 which are higher than the bump contacts 2 and which are made of brazing material are formed. When mounting the electronic circuit device on a substrate, the bumps 3 are melted and joined to the substrate. By this, the electronic circuit device does not deviate in position while the substrate is carried to a reflow process after the electronic circuit device is mounted on the substrate. Since the bumps 3 are formed higher than the bump contacts 2, only the bumps have only to be melted and joined to the substrate and there is no necessity of melting and joining the bump contacts 2 to corresponding terminal electrodes on the substrate.

Filed: 1979-02-13
Abstract: PURPOSE: To accurately predict the characteristics of a magnetic core with a simple configuration by contracting the characteristics of a semiconductor rectifier equivalently using a voltage follower circuit employing an operational amplifier, combining the characteristics with the magnetic core to form a similar circuit to the actual case.  
     CONSTITUTION: The forward voltage drop of a rectifier D d  in a rectifying circuit is applied to the non-inverting input terminal of an operational amplifier OP. Thus, the output of the amplifier OP is applied to a non-inverting inout terminal. When the amplifier OP oprates as a voltage follower and the output from the amplifier OP is applied to a resistor R, the voltage drop between the terminals P and N becomes zero. Output windings NL' are wound on two magnetic cores C r1 , C r2 , and are energized by AC power supplies E a1 ', E a2 ' through a rectifier D i  and a load resistor RL'. The control windings N c ' are connected in series with each other, and the control currents i c ' are supplied through the resistor R c ' to the windings N c '. Shorting windings N s ' are shorted through a resistor R s '. The time constants of the respective units are determined to the actual application. Thus, the characteristics of the magnetic cores applied to actual case can be accurately predicted with a simple configuration.

Title: Discharge lamp lighting device
Inventor: YAMAMOTO AKIRA
IPC: H05B41/24
Filed: 1988-01-26
Abstract: PURPOSE:To sufficiently give pre-heating at the starting time of a circuit while reducing an overcurrent and overvoltage by maintaining a timer in a state of reset when power supply voltage is lower than a certain level and further providing a circuit to stop oscillation of an output stepped transistor. CONSTITUTION:During the period wherein voltage of a negative terminal of a comparator IC1 does not reach reference voltage even when power supply is madeup and the main power supply V rises, output is H and the transistors Q1 and Q2 are in the state of ON and oscillation of the main circuit of an output stepped transistor 6 is not started, while charge of a capacitor C of a timer 7 is also not started. When control power supply Vc becomes higher than the reference voltage, output of the comparator IC1 becomes L, the transistors Q1 and Q2 become in the state of OFF, a timer 7 starts oscillation of the main circuit. At the time of power supply intermittence, the timer 7 can be kept in the state of reset. In this way, pre-heating can be sufficiently given at the time of starting the circuit so as to enable an overcurrent and overvoltage to the output stepped transistor to be controlled to the minimum.

Title: Thermal transfer recording method
Inventor: SUZUKI SHIGEKI
IPC: B41J2/355
Filed: 1992-01-30
Abstract: PURPOSE:To prevent the difference of dot diameters to be recorded from standing out for each recording block by a method wherein the recording of each line is performed by making thermal resistors, which are divided into a plurality of groups, heat alternately several times. CONSTITUTION:While carrying a recording paper and ink sheet, which are put together and inserted between contact surfaces of a thermal head and platen, blocks of thermal elements are made to heat alternately several times at the time of recording of each line. In the concrete form, respective heatings of blocks 11a-11d of the thermal elements are alternately repeated three times. Thus, by dividing the time which is required to heat the blocks 11a-11d of the thermal elements into three, the quantity to vary from a desired dot diameter in the recording of 1 line can be approximately evenly dispersed for each dot in the recording of the line. For this reason, even if a speed variation is generated when the recording paper passes the vicinity of the thermal head and platen, the difference of the dot diameters to be recorded does not stand out.

Title: Phase synchronizing oscillator
Inventor: FURUYA TERUO
IPC: H03L7/10
Filed: 1981-02-04
Abstract: PURPOSE:To ensure a wide capture range, by realizing the phase synchronism with the 1st feedback loop as well as the tuning of frequency using the difference signal voltage of the 1st feedback loop with the 2nd feedback loop, respectively. CONSTITUTION:The self-oscillating frequency starts to have a shift by some factor (such as the temp. and the like) from a state under which coincidence is secured between the self-oscillating frequency of a voltage tuning oscillator 1 and the frequency of the reference signal of a reference oscillator 6. In such a case, the pulselike difference signal voltage corresponding to the output signal is produced at the output of a phase detector 2. Then the phase synchronism is carried out with the 1st feedback loop, and at the same time the pulselike difference signal voltage is changed to a DC component through a DC converter 9 to be fed back to a tuning voltage circuit 4 with the 2nd feedback loop. Thus the output voltage of the circuit 4 is varied. As a result, the self-oscillating frequency is compensated to always ensure substantial coincidence between the frequency of the reference signal and the self-oscillating frequency.

IPC: G06T7/20
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To correct the error of an optical flow and to separate a moving object from its background in a moving image by calculating a convergent point of movement based on the relative movements of objects in a photographed moving image, calculating a parameter of the photographing mode of the moving image based on the convergent point and the movement, and extracting a relative motion parameter between a camera and the background even against plural moving objects. SOLUTION: The relative movements of objects are calculated in a photographed moving image and projected into a space of a different dimension. Then the peak of the projected movements is defined as the convergent point of the movement. Based on these convergent point and movements, a parameter is calculated in a photographing mode of the moving image. Thus, it is possible to extract the parameter of a camera divided into the zoom-in and zoom-out modes by projecting an optical flow, i.e., the movement of the moving image into a space of a different dimension. Then the movement of the moving object is corrected by the camera parameter, and the moving object is separated from its background in the moving image.

Title: Voltage dependent nonlinear resistor and manufacture thereof
Inventor: NEMOTO HIROSHI
IPC: C04B35/00
Filed: 1988-01-26
Abstract: PURPOSE:To obtain a high nonlinear starting voltage without adding SiO2 more than required and without lowering a baking temperature, by producing a sintered body principally composed of zinc oxide(ZnO) and containing a phase of zirconium oxide(ZrO2) crystals. CONSTITUTION:Powder of zirconium oxide(ZrO2) having an average particle size of 0.1-1mum is added to powder principally composed of zinc oxide(ZnO) in proportion of 5-20vol.%. They are mixed, shaped and baked. If the proportion of the added zirconium oxide (ZrO2) is lower than 5vol.%, the ZrO2 in the ZnO sintered body presents extremely low powder X-ray diffraction effect. If it exceeds 20vol.%, on the contrary, the flexural strength of the sintered body is decreased and properties such as discharge withstand current rating are deteriorated. A zinc oxide voltage dependent nonlinear resistor having a composition as described in the above can present a nonlinear starting voltage (V1mA) as high as 230V/mm or over.
