When a preinitialized load module 2 is modified, modifying command analysis means 401 registers modifying commands in a modifying command table 302, preinitialized load module loading means 402 loads a program portion 201 in a main memory 3, modifying command processing means 403 modifies a program image 301 according to the modifying command, preinitialized load module unloading means 404 reflects the image after modification to the program portion 201 and modifying command table unloading means 405 reflects the content of the modifying command table 302 to a modification history record portion 202. When the image in the modified portion is restored to the image before modification, modification restoring command analysis means 407 registers a modification restoring command in the modification restoring command table 303, modification history acquiring means 408 acquires the modifying command corresponding to the modification restoring command from the modification history record portion 202 and modification restoring means 409 restores the image before modification from the image in the portion indicated by the modifying command.

An extruded member of Al—Mg—Si aluminum alloy specially composed of Mg, Si, Fe, Cu, Zn, Ti, etc. which has the equiaxed re-crystallized grain structure in which intergranular precipitates 1 μm or lager are separate from one another at large average intervals and there are many cube orientations over the entire thickness region thereof so that it excels in both flexural crushing performance and corrosion resistance. The extruded member is suitable for use as automotive body reinforcement members which need outstanding lateral crushing performance under severe collision conditions as well as good corrosion resistance.

An optical device includes: a silicon substrate; a plurality of silicon oxide columns having a rectangular plan shape; and a cavity disposed between the columns. Each column has a lower portion disposed on the substrate. Each column has a width defined as W1. The cavity has a width defined as W2. A ratio of W1/W2 becomes smaller as it goes to the lower portion of the column. A core layer provided by the columns and the cavity can have the thickness equal to or larger than a few dozen μm easily. Therefore, connection loss between a light source and the device is reduced.

A method for manufacturing a dynamic quantity detection device includes bonding a semiconductor chip that includes a detection element for detecting a dynamic quantity to a stand using a bonding layer. Initially, a semiconductor chip is formed that includes a detection element used for correlating a dynamic quantity to be detected to an electric quantity and a processing circuit element used for a circuit that processes the electric quantity. Further, a bonding layer is placed on a stand. The semiconductor chip is then placed on the bonding layer and the semiconductor chip is bonded to the stand by sintering the bonding layer at 400° C. or lower in order to suppress a change in a characteristic of the processing circuit element.

A protective sheet is fixed to a jig, and regions of the protective sheet corresponding to regions where dicing-cut is to be performed are removed to form grooves. Then, a semiconductor wafer is bonded to the protective sheet at an opposite side of the jig, and the jig is detached from the protective sheet and the semiconductor wafer bonded together. After that, the semiconductor wafer is cut into semiconductor chips by dicing along the grooves of the protective sheet. Because the protective sheet is not cut by dicing, no scraps of the protective sheet is produced, thereby preventing contamination to the chips.

To allow an AP which performs operation based on a time of a system clock and another AP which performs operation based on a user-specified time to be executed concurrently in a data processing unit with only one system clock without having to change the time of the system clock, virtual system time setting means 5 receive a command or job start date and/or time from an input/output unit 2 and store it in a virtual system time storage area 4. In response to a system date acquisition function 6 or a system time acquisition function 7 from a command or a job, virtual system time converting means return either the date of the system clock when the date is not stored in the virtual system time storage area 4 or the date stored in the date storage area when the date is stored therein. The means also return either the time of the system clock when the time is not stored in the virtual system time storage area or the time of said system clock plus the time stored in said time storage area when the time is stored therein.
摘要:
In a method for manufacturing a semiconductor acceleration sensor, a movable portion including a mass portion and movable electrodes is formed in a single crystal silicon thin film provided on a silicon wafer through an insulation film by etching both the single crystal silicon thin film and the silicon wafer. In this case, the movable portion is finally defined at a movable portion defining step that is carried out in a vapor phase atmosphere. Accordingly, the movable portion is prevented from sticking to other regions due to etchant during the manufacture thereof.

An aluminum alloy containing Si: 1.5-12% (mass % here and hereinafter), Mg: 0.5-6% and, optionally, at least one of Mn: 0.5-2%, Cu: 0.15-3% and Cr: 0.04-0.35% and, further, containing Ti: 0.01-0.1% and the balance of Al and inevitable impurities, in which the average grain size of crystallized grains of Si system compounds is from 2 to 20 .mu.m and an area ratio thereof is from 2 to 12%. The alloy is melted to obtain a cast ingot having DAS (Dendrite Arm Spacing) of 10 to 50 .mu.m, which is then put to a soaking treatment at 450 to 520.degree. C. and then to extrusion molding. The aluminum alloy has excellent machinability with no addition of low melting metals.

摘要:
A semiconductor device has a semiconductor wafer having sensing portions exposed on a surface thereof and an adhesive sheet attached to the semiconductor wafer as a protective cap to cover the sensing portions. The adhesive sheet is composed of a flat adhesive sheet and adhesive disposed generally on an entire surface of the adhesive sheet. Adhesion of the adhesive is selectively reduced by UV irradiation to have adhesion reduced regions, and the adhesion reduced regions face the sensing portions. The protective cap can be produced with high productivity, and securely protect the sensing portions when the semiconductor wafer is diced and is transported.
