摘要:
A press machine, whose set operating conditions, pressing state, etc., can be easily grasped and whose safety and operability in the pressing operation can be improved, has a console panel (26) provided with a crank angle display (70), a pressing state display (80), a sheet switch (106) for inputting control information into a control section, and a multi-display (102) capable of displaying a plurality of pieces of the control information at a time. The crank angle display (70) can be constituted of multiple light emitting sections (72) arranged into a circle, and successive ones (72a) of the light emitting sections (72) whose number corresponds to the crank angle can be turned on.

A chromium-free treating liquid and treatment methods which are for imparting to a zinc or zinc alloy deposit a coating film which is highly corrosion-resistant, has a uniform appearance free from sag stains/puddle stains, has no failure concerning thickness unevenness, and has satisfactory adhesion. The surface-treating aqueous solution, which is for forming a corrosion-resistant coating film over a zinc or zinc alloy deposit, is characterized by comprising (a) an alkali metal silicate (M2O.nSiO2 (wherein M represents an alkali metal and n indicates SiO2/M2O molar ratio)), (b) a water-soluble or water-dispersible silane coupling agent, and (c) a water-soluble or water-dispersible glycidyl ether compound. One of the surface treatment methods for forming a highly corrosion-resistant coating film over a zinc or zinc alloy deposit includes bringing the surface of the zinc or zinc alloy deposit into contact with the surface-treating aqueous solution. The surface-treating aqueous solution is applicable also to the surface of a chemical conversion coating film formed on a zinc or zinc alloy deposit and free from hexavalent chromium or from chromium in any form. Namely, another surface treatment method for forming a highly corrosion-resistant coating film over a zinc or zinc alloy deposit comprises bringing the surface of a chemical conversion coating film formed on a zinc or zinc alloy deposit into contact with the surface-treating aqueous solution. Furthermore provided is a highly corrosion-resistant coating film formed by bringing the solution into contact with the surface of a zinc or zinc alloy deposit or with the surface of a chemical conversion coating film formed on a zinc or zinc alloy deposit.

摘要:
A cache memory unit connecting to a main memory system having a cache memory area in which, if memory data that the main memory system has is registered therewith, the registered memory data is accessed by a memory access instruction that accesses the main memory system and a local memory area with which local data to be used by the processing section is registered and in which the registered local data is accessed by a local memory access instruction, which is different from the memory access instruction.
摘要:
The present invention relates to a solder paste composition used for precoating an electrode surface with solder. A first solder paste composition is contains a solder powder and a flux, and a metallic powder made by metallic species different from metallic species constituting the solder powder and metallic species constituting the electrode surface in a rate of 0.1% by weight or more and 20% by weight or less based on a total amount of the solder powder. When these solder paste compositions are evenly applied onto an electronic circuit substrate for precoating, such a solder that does not generate any swollen portion, solder-lacking portion and variability in a height thereof can be formed irrespective of a shape of a pad.
摘要:
A solder paste composition used in a solder precoating method of forming solder bumps by forming a dam around electrodes on a substrate, filling a solder paste composition on the electrodes within opening parts surrounded by the dam, and heating the solder paste composition filled, so that solder is adhered to the surfaces of the electrodes. The solder paste composition contains solder powder, which is of a particle size distribution in which particles having a particle size of below 10 μm are present 16% or more, and a sum of the particles having a particle size of below 10 μm and particles having a particle size of 10 μm or more and below 20 μm is 90% or more. This enables to suppress occurrence of bump defects, and form solder bumps of a uniform height with a high yield by a solder precoating method using the dam.
摘要:
In a separating device that separates a processor configured to perform process by using data recorded in a cache memory connected to the processor, a stopping unit, upon receiving a processor separation request, stops the processor from performing a new process; and a separation executing unit, upon completion of process being performed by the processor, separates the processor after invalidating the data recorded in the cache memory.
