Abstract: PURPOSE:To prevent plating metal from penetrating into the parts covered with a plating resist mask when a bump is formed and, further, reduce a time for plating and form the bump efficiently by a method wherein a plating penetration blocking film is formed in a contact hole by electroplating. CONSTITUTION:A contact hole 14 is so formed as to reach a metal wiring film 12 which is formed as the lower layer of an insulating protective film 13 on a semiconductor substrate 11 from the upper surface of the insulating protective film 13. A bump electrode is formed in the contact hole 14 by an electroplating method so as to be connected to the metal wiring film 12. For that purpose, a plating resist mask 16 is formed on the insulating protective film 13 including the contact hole 14 by photolithography. Then a plating penetration blocking film 17 which prevents plating metal from penetrating into boundary between the plating resist mask 16 and the lower layer of the mask is formed in the contact hole 14 by an electroplating method. After that, the bump electrode is formed on the plating penetration blocking film 17 by an electroplating method.

Title: Compressor for co2
Inventor: KATO HIROYASU
IPC: F04C18/02
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To perform a stable oil feeding by preventing an oil feeding passage of lubricating oil of a compressor for CO2 from being clogged by foreign matter and to reduce manufacturing cost of the oil feeding passage. SOLUTION: Because differential pressure of discharge pressure and inlet pressure becomes large in a refrigerant compressor of an air conditioner using CO2 refrigerant, a restriction as a pressure reducing parts limiting flow rate becomes thin in diameter when a lubricating oil supply is performed by utilizing differential pressure and the restriction becomes easy to be closed by foreign matter. Therefore, an intermittent oil feeding mechanism is formed in an oil feeding passage without using pressure reducing parts, substantial oil feeding time is shortened and oil feeding amount is controlled. The intermittent oil feeding mechanism in the case of a scroll compressor can be constituted of a tip plate part 9d of a revolving scroll 9 and a discharge port 20a of the oil feeding passage 20 formed on an end face 7e of a housing 7.  As a result, because the discharge port 20a is opened and closed by revolution of the tip plate part 9d, substantial oil feeding time becomes short and the restriction is not required to be provided on the oil feeding passage 20.

Title: Vehicular starting assist device
Inventor: AOKI JUN
IPC: B60K23/08
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To make a dog clutch be surely turned off even if torque acts on this clutch when it is turned off after starting, in this unit performing a starting assist by installing a transmission mechanism, having this dog clutch being turned on or off by a solenoid, in space between an electric motor and an axle of a driven wheel, and in time of starting, having this clutch turned to ON, and then transmitting an output torque in the motor to the driven wheel. SOLUTION: An axial draft α is attached to each tooth side face of two dog teeth 110a and 111a of a movable dog 110 and a fixed dog 111 constituting a dog clutch 11. In this constitution, if torque acts on the dog clutch 11 and thereby frictional force by pressure contact between these teeth side faces themselves is produced there, pressing force pressing the movable dog 110 in the off direction is produced as an axial component force of pressure contacting force of these teeth side faces by the said draft, whereby the frictional force is offset by this pressing force, and thus the dog clutch 11 is surely turned off.
