Title: Multilayer printed wiring board
Inventor: YAMASHITA TAKAHIRO
IPC: H05K3/46
Filed: 1989-06-12
Abstract: PURPOSE:To prevent the generation fo press bonding failure by eliminating a copper foil coated part of a work substrate so that independent copper foiled parts shaped in small circle may remain with specified regularity, and using the parts subjected to elimination process as a residual gas discharge passage. CONSTITUTION:Product substrates 2a and 2b are laid out inside a work substrate 1 while small-circle residual copper foiled parts 3 are independently formed respectively on parts where the product substrates 2a and 2b are installed, are laid out in matrix or lined up linearly. During bonding contact the residual gas inside the product substrates 2a and 2b is discharged outside passing through a reticulated residual gas discharge passage 4. The pattern density of the remaining copper foiled parts 3 is constant per unit area when the gas is discharged. Therefore, the discharge amount of the residual gas passing through the residual gas discharge passage 4 is constant irrespective of the size of the product substrates. It is, therefore, possible to prevent the generation of press bonding failure.

Abstract: PURPOSE:To contrive as far as possible the reduction in the width of print dots in an initial stage of the use of printing electrodes and contrive a longer useful life of electrode elements, by a method wherein the width of electrode on one side is set to be larger than that of electrode on the other side, and the electrodes are finished by polishing. CONSTITUTION:The electrode elements 2, 2... provided on the surface of a substrate of the current-sensitized thermal transfer printing head to be positive poles are provided with a width l2 larger than the width l1 of electrode elements 3, 3... to be negative poles. Side parts 4 of the tip of the electrode element 2 are ground into a curved form by electropolishing to obtain the same width l1 as that of the electrode element 3. The electrode elements 2 are brought into close contact with a resistor layer of a thermal transfer film through a smooth contact surface, thereby providing a uniform current distribution, and the curved surfaces provided at the side parts prevent an electric field from being concentrated. Accordingly, abrasion liable to occur in the initial stage of printing can be prevented from occuring, and print dots with a fixed size can be formed over a long period of time.

Title: Voltage application circuit
Inventor: TOMARI NOBUHIRO
IPC: H02M3/07
Filed: 1993-06-18
Abstract: PURPOSE:To attain setting to a high output voltage by using a repetition control means to change an output voltage of a booster means to high or low values for a predetermined number of times and increasing a breakdown voltage of a 2nd transistor(TR) by a walk-out. CONSTITUTION:Prior to the use of an output voltage VPPI a control circuit 8 of a repetition control circuit 10 provides a clock signal phi to a charge pump 1 while turning off a TR 7 to allow the charge pump 1 to provide a high position VPP. Then the signal phi is stopped and the TR 7 is turned on to decrease the potential VPP. The operation of applying the high potential and the low potential to a 2nd TR 4 is repeated for a prescribed number of times to cause walk-out in the TR 4 thereby increasing the breakdown voltage. The voltage VPPI reaches a potential over the substantial breakdown voltage of the TR 4 by giving the signal phi to the charge pump 1 to allow the charge pump to provide an output of the voltage VPP. Thus, the output voltage is set to a high voltage.
