Title: Signal processing circuit
Inventor: TSURUGA SADAO
IPC: H03F1/22
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To provide a signal processing circuit in which no luminance is changed nor a white balance is unbalanced in the case of varying a color temperature for white color indication. SOLUTION: A processing circuit uses three variable gain amplifiers 102 in which primary color signals R, G, B are inputted. Three output terminals of a gain controller 202 are connected respectively to control terminals of the variable gain amplifiers 102 (102R, 102G, 102B). The output terminals of the three variable gain amplifiers 102 (102R, 102G, 102B) are connected respectively to output terminals (107R, 107G, 107B) of the signal processing circuit. The variable gain amplifiers 102 (102R, 102G, 102B) are used for drive adjustment and vary the signal amplitude respectively based on a control signal. The gain controller 202 controls the gain of the variable gain amplifiers 102 (102R, 102G, 102B) so that the luminance in the case of displaying a white color is unchanged and no hindrance is caused on the circuit operation.

Title: Operational amplifier circuit
Inventor: NAGAYAMA YOSHIHARU
IPC: H03F3/45
Filed: 1983-07-01
Abstract: PURPOSE:To improve the yield of a product by arranging program terminal for adjusting offset as an external terminal, and after forming a complate product through the while process, performing the measurement of the complete product and the adjustment of offset. CONSTITUTION:Under the state that the whole polysilicone resistors are not fused, a constant voltage is supplied to load resistors RL1', RL2' through TRs Q1n, Q2n which are turned on. When an offset voltage DELTAV reducing output voltage VOUT1 less than output voltage VOUT2 at the supply of the same voltage to the bases of TRs Q3, Q4 is generated, a polysilicon resistor RF1n is fused. Consequently, the TR Q1n is turned off and a constant voltage is supplied to the resistor RL1n, so that the load resistance of the TR Q3 is increased up to RL1'+RL1n. Since the output voltage VOUT1 is increased by the voltage drop of the resistor RL1n, the offset voltage DELTAV is offset.

Abstract: PURPOSE:To evade the deviation of a frequency, by connecting in series a capacitor to a piezoelectric element, and setting the temperature coefficient of the inter-terminal capacitance of the piezoelectric element and that of the inter-terminal capacitance of the capacitor so as to show a specific relational equation. CONSTITUTION:The temperature coefficient (alpha) of the inter-terminal capacitance Cd of the piezoelectric element 2 and the temperature coefficient (beta) of the inter-terminal capacitance Cx of the capacitors 3 and 4 are set at relation as beta=-alpha/{N-alpha(1+N)} (where, N=Cx/Cd>>1 in equation). And as the capacitor Cx to be connected in series to a piezo-resonator, the capacitor having the temperature coefficient (beta) to satisfy the equation is selected. And the superposing planes of the piezoelectric element 2 and first and second capacitor units 3 and 4 are bonded with a bonding agent 14 keeping a prescribed interval to permit the vibration of vibration electrodes 6a and 7a. Thus, since the capacitors 3 and 4 are connected in series to the piezoelectric element 2 and the capacitor which satisfies the above stated equation is selected, it is possible to evade the characteristic change of the piezoelectric element due to temperature change.

Inventor: SUZUKI KENSUKE
IPC: H01L23/08
Filed: 1984-06-08
Abstract: PURPOSE:To bring a semiconductor pellet and a slag electrode into contact completely by bringing residual stress in a glass sleeve in a welding section between the slag electrode and the glass sleeve to a specific value or more. CONSTITUTION:A semiconductor pellet 4 in which a bump electrode 3 is fixed to one surface of a semiconductor base body 2 to which a P-N junction is formed is arranged between a pair of slag electrodes 1. A glass sleeve 5 is mounted extending over the electrodes 1, and the sleeve 5 is melted through heating and welded to the electrodes 1, thus hermetically sealing the pellet 4. When a difference between the thermal expansion coefficients of the electrode 1 and the sleeve 5 is increased at that time, residual stress is generated in the sleeve 5, and residual stress through which the sleeve 5 positioned at a pellet 4 section is drawn near is generated in the sleeve 5 in order to relax said residual stress, thus improving pressure welding force between the electrode 1 and the pellet 4. When residual stress in the sleeve 5 in a welding section extends over 60kg/cm<2> or more, defective disconnection is not generated due to intermittent conduction.

IPC: H04Q11/04
Filed: 1979-09-19
Abstract: PURPOSE:To improve transmission efficiency by superposing a dial signal in the form of DC pulses directly upon a sound as it is and by transmitting it after DELTAM modulation. CONSTITUTION:Dial transmission input signal SS, after having a high frequency component of about 100Hz or above removed through low-pass filter 31, is inputted to DELTAM coder 32 and sound transmission input 4WS is similarly inputted to coder 32 by way of band-pass filter 33.

Abstract: PURPOSE:To contrive the improvement in a transmission performance of high frequency signals by forming a conductor pattern for impedance control on a plane of the opposite side of a tape-shape substrate having flexibility to the side for a conductor pattern for signal transmission. CONSTITUTION:A substrate 2 for a wiring board 1 is composed to be tape form out of insulating members having flexibility. On one side of this substrate 2, a plenty of conductor patterns 3 for signal transmission having a predetermined thickness and a predetermined width consisting of copper or the like are arranged along a longitudinal direction of said substrate 2 in a predetermined intervals. Meanwhile, on another side of the substrate 2, that is, on the upside, a conductor pattern 4 for impedance control which is to be connected with an earthing potential is formed over the almost whole surface. Such wiring board 1 is used for electrical connection of a probe card 11, for example, with a connection terminal 12 of a test head. Particularly, when high-frequency signals are used for test measurement, impedance alignment of the probe card 11 and a tester (the connection terminal 12) is often made previously. In this case, the alignment of an impedance of the flexible wiring board 1 to that of a probe card 11 is done. Accordingly, high frequency signals can be transmitted better than in a conventional method and the accurate measurement can be made.
