摘要： A keyboard apparatus for an electronic musical instrument has a metallic keyboard chassis and a balance rail provided on the keyboard chassis. A plurality of pins are provided on the balance rail. The pins and the balance rail constitute fulcrums for swingably supporting white keys and black keys. A hammer is provided in a rear side of each of the white and the black keys so as to be swingable by swinging of each of the respective keys by a second fulcrum comprising oval cross sectional shafts extending outwardly from the side surface of one of the hammer and a bearing member, the side surface extending perpendicular to a direction of swing movement of the hammer and a pair of bearing recesses for pivotally receiving the shaft, the bearing recesses being formed in the other of the hammer and the bearing member. Each of the bearing recesses has a guide slot for guiding each of the shafts from outside into the bearing recess for assembling. A split groove is provided in the other of the hammer and the bearing member for receiving the one of the hammer and the bearing member. First abutment surfaces are provided so as to project in an axial direction of the shafts from the side surface of the one of the hammer and the bearing member around the shafts, the first abutment surfaces being in sliding contract with the slit groove. Second abutment surfaces are provided by reducing the width between the side surfaces and lateral vibration preventing surfaces are provided inside the split groove in close proximity to the second abutment surfaces.

摘要： In a semiconductor device, a connection conductive layer is formed by patterning on a p-type semiconductor substrate. A silicon nitride film is formed on the connection conductive layer with an insulating layer. A silicon oxide film is formed on the silicon nitride film. The silicon oxide film is provided with a hole. The silicon nitride film is exposed at a bottom of the hole. The hole is located immediately above the connection conductive layer. Thereby, a thickness of the insulating layer on a fuse element which can be blown can be controlled easily in the semiconductor device.

摘要： A keyboard device for an electronic musical instrument comprises a keyboard chassis, keys rotatively arranged on the keyboard chassis, and a key switch arranged beneath each of the keys for detecting a key status of each key. Each key has a switch-depressing projection arranged just above the key switch, and a hammer-depressing projection for depressing a hammer when the hammer is provided, with the switch-depressing projection and the hammer-depressing projection being formed adjacent to each other in one piece.

摘要： A portion of a cell plate 91 extending upon a field oxide film 107a and a silicon oxide film 123 is referred to as a lower layer interconnection film 109. The lower layer interconnection film 109 has a concave shape. A through hole 95a is formed in a silicon oxide film 93 reaching the bottom of the concave shape lower layer interconnection film 109. The depth of the through hole 95a is greater in comparison with the case where a through hole is formed on an upper face portion 123a of the silicon oxide film 123. Because the depth of through hole 95a is great, the thickness of the tungsten film 101a formed in through hole 95a becomes thicker. This eliminates the problem that all the tungsten film 101a in the through hole 95a, and then a portion of the lower layer interconnection film 109 are overetched. Therefore, electrical connection between the upper layer interconnection layer 103a and the lower layer interconnection layer 109 can be ensured.
摘要翻译：在场氧化膜107a和氧化硅膜123上延伸的单元板91的一部分被称为下层互连膜109.下层布线膜109具有凹形。在到达凹形下层互连膜109的底部的氧化硅膜93中形成通孔95a。与在上表面部分形成通孔的情况相比，通孔95a的深度更大 123a。由于通孔95a的深度大，所以形成在通孔95a中的钨膜101a的厚度变厚。这消除了通孔95a中的所有钨膜101a以及下层互连膜109的一部分被过蚀刻的问题。因此，可以确保上层布线层103a和下层布线层109之间的电连接。

摘要： A keyboard apparatus for an electronic musical instrument has a metallic keyboard chassis and a balance rail provided on the keyboard chassis. A plurality of pins are provided on the balance rail. The pins and the balance +*rail constitute fulcrums for swingably supporting white keys and black keys. The fulcrums for the black keys are disposed on the same line with, or in front of, the fulcrums for the white keys. Hammers are provided in a rear of the keys so as to be swingable by swinging of each of the respective keys. The hammers are disposed on the same axis of rotation, and a position for the black keys to operate to swing the respective hammers is located in front of a position for the white keys to operate to swing the respective hammers such that an angle of rotation of the respective hammers becomes substantially equal to each other. A stopper member for restricting the swinging movement of the keys or the hammers are provided in a rear upper portion of the keys. The metallic key board chassis is divided into a front chassis portion and a rear chassis portion, and the two are connected by metallic reinforcing beams.

摘要： A memory cell array is divided into four blocks #1 to #4. The blocks #1 and #3 are operated when a row address signal RA.sub.8 equals "0". The blocks #2 and #4 are operated when the row address signal RA.sub.8 equals "1". A spare row sub-decoder is provided in each of the blocks. Spare row sub-decoders in the blocks #1 and #2 are connected to a spare row main decoder through a single spare decoder selecting line. The spare row sub-decoders in the blocks #2 and #4 are connected to the other spare row main decoder through another spare decoder selecting line. The spare main decoders are responsive to the row address signal RA.sub.8 and row address signals RA.sub.2, RA.sub.2, . . . , RA.sub.7, RA.sub.7 for operating a spare row sub-decoder in a block which is in the operating state.
