There are here disclosed a method for removing a titanium-based film from a honeycomb-molding die having on the surface of a base material coated with the titanium-based film, and a method for removing an oxide of titanium from a honeycomb-molding die having the oxide of titanium adhered/deposited on the surface of a base material. In each method, a removing solution comprising a mixture of an acid and hydrogen peroxide is used. According to the methods for removing the titanium-based film and the oxide of titanium, a large amount of the titanium-based film as well as the oxide of titanium adhered/deposited on the base material of a honeycomb-molding die can be removed by use of a small amount of the removing solution without corroding the base material of honeycomb-molding die while re-deposition of dissolved titanium ions on the base material is prevented.

An ink cartridge is detachably connected to a record head and has a plurality of ink storage chambers 11 (containing third ink storage chamber 17) for containing ink whose concentration gradient occurs and an ink flow passage 18 for making the ink storage chambers communicate with each other. The ink flow passage 18 is implemented as such an ink flow passage where ink in a high-concentration ink layer a formed in a lower area in the ink storage chamber 11 and ink in a low-concentration ink layer b formed in an upper area flow and merge as ink is supplied to the record head.

A die for extrusion-forming a honeycomb structure which includes: a die base provided with ceramic puddle introducing holes and slits in communication with the ceramic puddle introducing holes; and a substrate layer, which roughly defines the final width of the slits, and a surface layer, which precisely defines the final width of the slits, formed on the die base in this order so that the final width of the slits becomes 15 to 200 μm, wherein the surface layer is made up of tungsten carbide particles which are 5 μm or less in average particle diameter and contain W3C as a main ingredient. According to this invention, there is provided a die for extrusion-forming a honeycomb structure which can restrain fluctuation in extrusion-forming speed among its parts and resistance to pushing force, both caused at the time of extrusion-forming, to be very small and is superior in productivity and durability.

摘要:
A peripheral control processor for controlling data communication between a host processor and a peripheral unit in response to command signals applied to the host processor. The peripheral control processor has an idle time or a standby condition when data communication is not required. When the peripheral control processor is idle or in a standby condition, a control circuit, within the processor inhibits a control clock signal which activates transistor elements of an internal circuit in the processor. Therefore, unnecessary power comsumption is reduced during idle time or a standby condition. Further, the control circuit can produce the inhibition signal by using the command signals used for data communication. Therefore, no new signals or terminals are required for applying input signals to the control circuit.

A data processing system having an improved output circuit which can set its output terminal optionally at a high impedance state and at a voltage clamped state in a standby mode. The system includes an output circuit capable of setting the output terminal at the high impedance state and the voltage clamped state in response to a first control signal and a second control signal, respectively.
摘要:
For generating a working address in a central processing unit of a computer by combining the content of a specified one of a plurality of relocation registers with the content of one of a plurality of general purpose registers that is specified by a datum given to the central processing unit, an addressing system comprises a mode register for producing a register output signal at a time, a decoder for deriving a decoder output signal from the datum, and a selecting circuit responsive to the register and the decoder output signals for selecting one of the relocation registers as the specified relocation register. Preferably, combinations of the signals produced by the mode register and those derived by the decoder from the data specifying at least predetermined ones of the general purpose registers are in one-to-one correspondence to the relocation registers. When the mode register has a plurality of one-bit memory cells, a mode register signal stored in the mode register may be changed by storing a one-bit signal derived from a result of operation of the central processing unit in one of the mode register memory cells that is selected by the decoder output signal.
摘要:
An information processing apparatus of the type in which information is transmitted among a plurality of information handling units such as a central processing unit, memories, input-output units and the like through a common bus is disclosed. The common bus is divided into first and second data buses with the central processing unit connected to the first data bus and at least one memory unit and at least one input-output unit connected to the second data bus. Gating units are coupled between the first and second data buses to transfer data between the first and second data buses. Since the common bus can be divided by the gating units according to demand into the first and second data buses, the information processing apparatus is capable of processing a plurality of programs in parallel.
