摘要:
An ultrasonic bonding equipment for manufacturing a semiconductor device comprises a tip portion. The tip portion has a top surface which is faced to a member to be bonded, and propagates an ultrasonic vibration to the top surface. A plurality of protruding portions are provided on the top surface. Each of the protruding portions has: a first pair of opposite side surfaces inclined with respect to the top surface; and a second pair of opposite side surfaces substantially vertical to the top surface. A semiconductor device comprises: a semiconductor chip; a lead; and a bonding strap electrically connecting the semiconductor chip and the lead. A recess is formed on an upper surface of the bonding strap in at least one of a first region where the bonding strap and the semiconductor chip are connected and a second region where the bonding strap and the lead is connected. A first pair of opposite side surfaces of the recess are inclined with respect to the upper surface of the bonding strap, and a second pair of opposite side surfaces of the recess are substantially vertical to the upper surface of the bonding strap.

The present invention provides a support structure for a latch actuating lever and a lock actuating lever, which realizes a small and compact door lock apparatus for vehicles. The door lock apparatus includes a latch mechanism for maintaining a vehicle door in a closed state relative to a vehicle body, a latch actuating link coupled to the latch mechanism and actuating the latch mechanism to place the vehicle door in an openable state relative to the vehicle body, a lock actuating link for connecting or disconnecting the latch actuating link to or from the latch mechanism and thus making the latch mechanism operable or inoperable when the latch actuating link is actuated, and a base unit for supporting the latch actuating link and the lock actuating link. The base unit includes an annular support and a support shaft held in the annular support. At least one latch actuating lever, constituting the latch actuating link, is rotatablely supported on either one of the annular support and the support shaft, and at least one lock actuating lever, constituting the lock actuating link, is rotatablely supported on the other one of the annular support and the support shaft.

A water treatment method according to the present invention comprises adding an amphoteric polymer flocculant to polluted water to flocculate suspended solids so that the polluted water becomes treated water, and filtering the treated water. An inorganic flocculent can be added to the treated water after flocculation treatment before filtering the treated water.

This invention aims at providing a method of searching for substances that can selectively suppress apoptosis in cardiovascular cells. This objective is attained by providing a method of screening for therapeutic and/or prophylactic agents of cardiac disease, which comprises the steps of inducing apoptosis in cultured myocardial cells and/or cultured vascular endothelial cells; treating the cells with a Cl− channel blocker under test; and evaluating the therapeutic and/or prophylactic effect of the blocker under test on cardiac disease by checking to see if it can suppress apoptotic cell death in the cardiovascular cells or vascular endothelial cells.

An image forming apparatus includes an authentication unit, a communication unit, a function availability data obtaining unit, a usage authorization data obtaining unit, and a display controller. The authentication unit authenticates a user. The communication unit communicates with an external device connected thereto. The function availability data obtaining unit obtains, from a memory, function availability data that defines whether or not a function related to the external device is available. The usage authorization data obtaining unit obtains usage authorization data indicating whether or not the user is authorized to use the function. The display controller causes, when the external device is connected to the communication unit, a display to display a screen related to authentication of the user, an image related to the function, or an image for notifying the user that the function is unavailable, in accordance with the function availability data or the usage authorization data.
摘要:
The present invention particularly relates to a foundation body and method of disposing additional reinforcing materials in foundations formed with a reinforced base which obtains a high underpinning strength with respect to detaching loads. The natural ground 4 is excavated. A plurality of rod shaped additional reinforcing materials are fixed in the peripheral earth which extend radially from the formed main foundation body and which are disposed at fixed intervals in the radial direction. The additional reinforcing materials are disposed so as to be corresponded with the direction of minimum principal strain in the earth peripheral with respect to the foundation body when a detaching force acts.

A complex recording apparatus includes a housing. A platen glass is provided at an upper portion of the housing, and an exposure lamp which reads a first original put on the platen glass is provided within the housing. Furthermore, above the housing, a platen cover which holds the first original put on the platen glass and a reading head which reads a second original supplied from an outside are independently provided.
