Title: Method for adjusting plating amount in continuous plating on metallic sheet
Inventor: ISHII TOSHIO
IPC: C23C2/40
Filed: 1988-04-27
Abstract: PURPOSE:To easily adjust a plating amt. in a short time by changing the feed rate and contact supply angle of a plating metal at the time of bringing the plating metal into contact with a moving heated metallic sheet to deposit a plating film. CONSTITUTION:A band steel 10 is heated in a heating furnace to a temp. higher than the m.p. of zinc, and continuously traveled in direction of the arrow. A zinc plating material 20 is drawn out by pinch rolls 30-33, preheated by a heater 40, and brought into contact with the band steel 10 to deposit a zinc plating film 21 on the band steel surface. The film 21 is then uniformized by a surface regulator 50. Under such a constitution, oil hydraulic cylinders 60-63 and 70-73 are actuated, as required, to incline the vertically supplied plating material 20, hence the contact supply angle at the contact point is changed, and the feed rate of the plating material 20 is changed. By this method, the plating amt. on the band steel 10 is easily adjusted in a short time.

IPC: H05K3/34
Filed: 1993-04-30
Abstract: PURPOSE:To obtain a printed wiring board capable of preventing soldering failures of electric components which are surface-mounted and securing soldering reliability. CONSTITUTION:A projection 11 is made at a land-to-land resist portion 4a positioned between lands 3a of a solder resist 4 possessed by a printed wiring board main body 1 having a pair of lands 3a which are exposed where the projection is unique from the resist portion 4a and projects from the surface of the resist portion 4a. This projection 11 serves to segment a bonding agent sump 12 of a bonding agent which bonds an electric component 9 laid out over the lands 3a and surface-mounted into the resist portion 4a partitioning a space between the bonding agent sump 4a and the lands 3a with the projection 11. This construction makes it possible to restrict the spread of the bonding agent and prevents the bonding agent from coming to the lands 3a, thereby inhibiting soldering failures of the electric component 9 about the lands 3a.

Title: Cmos inverter circuit and its design method
Inventor: RII PIITAA
IPC: G06F17/50
Filed: 1993-05-06
Abstract: PURPOSE:To reduce deterioration due to hot carrier to the utmost by using simulation of the circuit and its reliability and taking the capacitive coupling into account. CONSTITUTION:In the inverter in which a predetermined voltage is applied to a gate 308 of an inserted NMOSFET, an optimum voltage is selected by using the result of the hot carrier simulation by taking an actual waveform and capacitive coupling into account and the deterioration is minimized. For example, a gate voltage is selected between 0.81Vcc and 0.93Vcc to set the service life of the device within a range smaller than the optimum value by one digit order. In the case of the inverter in which the gate 308 of an inserted MOSFET 307 is connected to the input, a depletion device is adopted for an inserted NMOSFET 307. For example, when a nominal threshold voltage of a driver device 105 is 0.72V, the service life of the device is selected within a range shorter than the optimum value by one digit order by selecting a threshold voltage of the inserted MOSFET 307 to be a voltage between -1.0V and -0.81V.
