Title: Pad for forming solder bump
Inventor: KAMIOKA YOSHITO
IPC: H05K3/34
Filed: 1995-03-22
Abstract: PURPOSE: To improve the connecting strength of a solder bump by constituting the solder bump of a circular or polygonal main part and auxiliary parts which are formed adjacently to the main part and have smaller areas than the main part has. CONSTITUTION: The surrounding area of a pad 3 for forming solder bump is formed to have a recessed cross section and covered with a resist 2a. Two auxiliary parts 1 having larger areas than the pad 3 has are formed adjacently to the pad 3 by removing part of the resist 2a. At the time of forming a solder bump, a flux is applied to the surfaces of the pad 3 and resist 2a and a solder ball or punched solder piece is mounted on the pad 3 by utilizing the stickiness of the flux, and then, the solder is reflowed. Since the solder spreads to the auxiliary sections 1 in a wetting state after it wets the pads 3, the gas produced when the boiling flux is discharged from the auxiliary sections 1 and the flux is pushed away from the pad 3 and discharged from the auxiliary sections 1 as the solder spreads on the pad 3.

Title: Method and device for compression forming of vegetable fiber material
Inventor: NISHI MASAKI
IPC: A23N17/00
Filed: 1983-04-13
Abstract: PURPOSE:To compress efficiently a vegetable fiber material to a compact and specified shape in a narrow space by subjecting successively and continuously three times of compression working by using three units of compressors. CONSTITUTION:A raw material is charged into the space G in a precompressing chamber 1 by which the material is compressed preliminarily to the volume of a space E. The raw material having varying densties internally is thus uniformly compacted. A pressing member 5 is then lowered by a hydraulic cylinder 6 to press the material in the space E toward the bottom wall 4a in a secondary compressing chamber 4, by which the material is compressed secondarily. The material to be worked is further compacted by such operation and is cut to four blocks by the edges 9 of a slicer according to said operation. When the edges 9 of the slicer are retreated, the gap remain at three points of the material to be worked. A hydraulic cylinder 8 is thereafter extended and the material to be worked is pressed toward the right by a pressing member 7 for final compression and is further compacted. The compact shape is thus maintained.

Abstract: PURPOSE:To stabilize the operation by using two pieces of FETs of an enhancement type whose threshold voltages are different, fetching a voltage difference at the time when a current of a prescribed ratio is allowed to flow to them and setting it as a reference voltage. CONSTITUTION:This circuit consists of N channel MOSFETs Q61-Q63 and P channel MOSFETs Q64, Q65, and a positive voltage is applied from an external power source Vcc. In this case, the N channel MOSFETs Q61-Q63 consist of enhancement type FETs Q62, Q63 having a standard threshold voltage VTE and an enhancement type FET Q61 having a threshold voltage VTEE being higher than VTE. In such a way, since two pieces of FETs of an enhancement type whose threshold voltages are different are used, a difference of those threshold voltages can be made small enough. Accordingly, characteristics of two pieces of FETs can be fitted easily, and a stable reference voltage can be obtained. In such a way, the operation is stabilized.
