Title: Evaporating method for minute solder bump
Inventor: FUJIWARA KOUICHI
IPC: H01L21/60
Filed: 1982-01-13
Abstract: PURPOSE:To form the minute solder bump by inhibiting the deformation of a metallic  mask and the temperature rise of an evaporated substrate due to radiant heat in case  of solder evaporation. CONSTITUTION:The temperature rise of the evaporated substrate due to radiant heat  and the heat of solidification of a solder material in case of evaporation is inhibited  by cooling a metallic mask holder manufactured by oxygen-free copper, which has  excellent thermal conductivity and from which a gas is hardly degassed in vacuum, by liquid nitrogen. A Fe-Ni alloy having a small thermal expansion coefficient such as a  Fe-36wt% Ni (Invar) alloy conformed to the thermal expansion coefficient of the  evaporated substrate consisting of a Si wafer is used as the quality of mateial of the  metallic mask. An alloy such as a three-element alloy, which has the melting point of  60 deg.C and consists of In-33% Bi-16% Sn, is used as a solder material, and the metallic  mask is fast stuck onto the evaporated substrate composed of the Si wafer and solder  is evaporated in vacuum. Accordingly, the minute solder bump can be evaporated in a  short time because the closely adhesive property between the metallic mask and the  evaporated substrate in case of vacuum evaporation is improved remarkably and the cooling performance of the evaporated substrate is excellent, and the solder bump  with small crystal grain size can be manufactured by cooling the evaporated substrate  at a low temperature.

When the output is over the reference voltage, A/D conversion 6, memorization 7 and operation 8 are given respectively. Then voltage limit exponent α and surge resistance quantity N are calculated based on Eqs (1) and (2), and thus the agerage value and the reference deviation are obtained to be delivered through printing part 9.

Title: Easy-opening can lid unseparated tab
Inventor: ARAI SHINICHI
IPC: B65D17/32
Filed: 1988-01-12
Abstract: PURPOSE:To smoothly open a can with a small force and prevent the contents from splashing by a method wherein a function for first opening a crack on a can lid is performed only by a tab bottom and a function for propagating the crack is performed by a tab crest. CONSTITUTION:The shortest distance from a tab crest 7b to the short axis of the tab through the center O of a tab fixing portion 8, that is the length from the tab top 7b to the Y-Y axis, is assumed to be 11. The shortest distance from a tab bottom 7b to said axis is assumed to be 12. The ratio 11/12 is made to be 1.5 or larger but smaller than or equal to 3.5. This enables the bottom 7a and the crest portions 7b, 7c which are located on the both sides of 7a to function efficiently in the initial and middle stages, respectively, making it easy to open a can. Further, when the can is opened, a protruding portion 16 is formed that the bottom 7a, which is the widthwise center of a tab tip 7, first comes into contact with the opening portion of the can lid. This enables an opening force to be further concentrated on a yielding line 3 in the vicinity of the initial opening area B. The protruding portion 16 like this can be formed by adjusting a folded amount and angle of a curled portion for strengthening the tab.

Title: Dc branch circuit

IPC: H04L29/10
Filed: 1986-01-10
Abstract: PURPOSE:To prevent data transmission from being blocked by feeding back the output of a priority encoder to a gate circuit and controlling the set of a flip-flop by a request send signal. CONSTITUTION:An output signal 21 of a priority encoder 2 is outputted to a selector 1 and fed back to AND gates 9-14 via a feedback circuit at the same time. When no request send signal of each terminal equipment exists, the input to the priority encoder 2 is all at '0' and since the output is all at '1', each AND gate is all opened through a 3-input AND gate 35. When a request send signal of a terminal equipment is confirmed, a corresponding data among input signals 22-27 is outputted as a data output signal 34, each AND gate is closed at the same time and the request send signal of other terminal equipments is not received until the reset of the corresponding flip-flop. Thus, it is prevented that a preceding request send signal is blocked by a succeeding call signal.
