摘要:
A semiconductor device is provided which comprises a memory mat formed by dividing a memory into a plurality of blocks and a circuit arrangement disposed at every memory mat block for generating access suppression signals at least for defective memory cells within that block. Using this arrangement, the access speed to a redundant memory cell array for relieving the defects is increased so that a semiconductor memory device capable of a high speed operation is obtained.

An arrangement which is particularly effective for decoders in semiconductor memory circuits which use, for example, common NMOS to receive one input for a plurality of logic decoder gates is provided includes a plurality of logic gates each having a first input terminal for respectively receiving first input signals and each being coupled to a common node. In one embodiment, first and second switching elements are also coupled to the common node. The first and second switching elements are both coupled to a second input terminal for receiving a second input signal which is common to the plurality of logic gates, and both operate complementary to one another in response to the second input signal. An improved read/write arrangement is also provided for such semiconductor memory circuit which includes circuitry to prevent connection of a common read line to the data lines during the writing operation. This enhances the writing speed by removing the load of the common read line during writing.

摘要:
An improved jet dyeing process for fibrous articles containing polyester-type synthetic fibers which comprises heating the bath liquid while moving said fibrous article at a rate of 80 to 300 meters/min. in a bath containing no dye; adding a dye liquor at a rate of not more than 20 liters/sec. when the temperature of the dye bath has exceeded 110.degree.C; and successively dyeing the fibrous article at a temperature of more than 110.degree.C. while moving it at the above rate, and an apparatus suitable for practising aforesaid jet dyeing process.
摘要:
A charging system has a battery pack and a charging device. The battery pack has a battery cell and a plurality of identifiers that identify a configuration of the battery cell. The charging device has a charging unit, a signal transmission unit, a reading unit, and a control unit. The charging unit charges the battery pack. The signal transmission unit transmits a first signal and a second signal to the battery pack separately to read the plurality of identifiers when the battery pack is attached to the charging unit. The reading unit reads the plurality of identifiers according to the first and second signals to determine the configuration of the battery cell. The control unit controls the charging unit according to the configuration of the battery cell.
摘要:
A fuel filter device includes a bag-shaped filter member and is adapted to be attached to communicate an inner space of the filter member with a fuel suction opening in a fuel tank. The filter member is configured in a multilayer structure. At least one layer of the filter member is configured to serve as an inhibition layer having a structure to prevent water in a fuel tank form coming into the inner space of the filter member by a pressure applied to the filter member when the water is frozen.
摘要:
A musical apparatus which outputs music under the control of various musical control instructions where the desired musical control instructions are reliably determined by the movement of an object in an operation space, and where the musical control instructions are varied by changing the state of motion of the object in space. The musical apparatus performs musical control instructions whose contents are based on the state of motion of an object in motion within a specified operation space. The musical apparatus may have at least one light source which shines light into said operation space, at least one light sensor which receives light which has been reflected by an object in the space so that it has at least two light paths which reach from the light source to the light sensor via the object, so that a detection values is output according to the quantity of light received via a respective one of the light paths, and a musical controller which outputs music and controls a musical function when the correlation between the current values of the detection values of the various paths satisfies a specified relationship.
