Title: Manufacturing method of tape carrier
Inventor: OGIWARA YOSHIAKI
IPC: H05K3/24
Filed: 1990-03-19
Abstract: PURPOSE:To eliminate the drop in bonding strength of a copper circuit or circuit peeling and hence improve bonding reliability by applying electroless copper plating to a circuit with a plating solution which contains tartaric acid complex ions after the formation of a conductor circuit and applying finish plating. CONSTITUTION:Prior to finish plating, such as Au plating or Sn plating, the surface of a circuit undergoes electroless copper plating with a plating solution which contains tartaric acid complex ions. More specifically, immediately after a conductor circuit is formed by etching a coated copper foil for processing, there exist numerous micro-defects, such as pin holes produced during electrolysis or left extension or etching processing for circuit formation. However, electroless copper plating is applied to a conductor circuit where there exist micro-defects, a plating solution will penetrate the micro-defects so that copper may separate even in the defects, thereby enabling the defects to be covered. This construction makes it possible to improve connection reliability with a semiconductor device without degrading circuit bonding power induced by finishing plating.

Title: Driving method of optical control element
Inventor: SUZUKI MASAYUKI
IPC: G02F1/01
Filed: 1984-04-06
Abstract: PURPOSE:To obtain an optical control element which has no special restriction in an incident light and an incident form, etc. of the incident light, and also is excellent in its stability and durability, by driving a temperature control means so that power of a specified range is consumed. CONSTITUTION:A granule 5 is obtained by heating resistors 3a, 3b and generating a vapor bubble in a liquid 4. That is to say, when an impressed voltage of the resistor 3a is lowered from a state that the granule 5 is held in the vicinity of the resistor 3a by impressing a voltage of 1.5V to the heating resistor 3a, and simultaneously, the voltage of 1.5V is applied to the heating resistor 3b, the granule 5 moves immediately to the vicinity (shown by a dotted line) of the resistor 3b. In this way, a position of the granule 5 in the liquid layer 4 can be controlled by selecting a heating resistor to which a voltage is impressed. Based on a fact that the power consumption is proportional to a square of an impressed voltage, in order to maintain the granule 5 when the minimum power consumed in the heating resistor for forming a vapor bubble is W0, it is desirable to consume power W of a range of 0.1W0<=W<=0.95W0, in the heating resistor.

Title: Measuring method of water contents in ink
Inventor: HIROKAWA KOUICHI
IPC: G01N27/06
Filed: 1978-06-07
Abstract: PURPOSE: To obtain printed matter of always highest quality by covering the surface of a metering roller with hydrophilic material, electrically detecting the water film deposited and formed on the surface to measure the water contents in ink and automatically correcting the rate of water feed.  
     CONSTITUTION: Since the surface of a metering roller 14 is covered with hydrophilic material, water contents are separated from the ink deposited on the metering roller 14, forming a water film on the surface. This water film produces an electric resistance between contactors 16 as it has conductivity. This resistance between the contactors 16 changes the balance of a bridge part 40, then the potential difference from an auxiliary power source 43 enters a water volume regulating part 41, where it is compared with the preset value and the output thereof is transmitted to a relay drive part 42. In the relay drive part 42, this signal is amplified to operate or stop the relay and send the signal to a water feed regulating mechanism 20, which in turn varies the contact timing of a water ductor 9 and distributing roller 5 thereby regulating the rate of water feed.

Title: High voltage generating circuit
Inventor: IMAMURA NOBUAKI
IPC: H04N3/185
Filed: 1988-03-23
Abstract: PURPOSE:To make a high voltage stable by opening a gate by a control current having a pulse width corresponding to the drop of a high voltage output due to a high voltage current and boosting an added voltage by a multiple voltage circuit so as to apply the resulting voltage to a high voltage output coil. CONSTITUTION:When a high voltage output current flows to an anode 16 of a cathode ray tube 15 and a high voltage output voltage is lowered, the voltage detected by a voltage detection section 9 is also reduced. Thus, when a comparator amplifier 22 compares its detection voltage and a triangle wave voltage, since the level of the detected voltage is lowered, the period of the triangle wave voltage in excess of the detected voltage is increased. Since the width of a rectangle control signal outputted from a differential amplifier 32 is increased, the period to open the gate of a switching circuit is extended and the summing voltage applied to the high voltage coil is increased. The summing voltage outputted from the switching circuit 23 is boosted by plural times by a multiple voltage circuit 46 and then the resulting voltage is fed to the high voltage coil. Thus, the high voltage is made stable.
