摘要:
A concentration correcting apparatus comprising a correction coefficient calculating means and a correcting means is shown and described. The correction coefficient calculating means calculates a correction coefficient for correcting the concentration of the material when the actual density of the medium at the measurement of the material is calculated in terms of the density of the medium under the reference temperature and pressure, from the results of the temperature measuring means and the pressure measuring means. The correcting means corrects the results of the material measuring means to a concentration under the reference temperature and pressure on the basis of the correction coefficient. The measure value of the material in the medium under constant temperature and depressure is virtually calculated by correcting the measured value by using the correction coefficient while calculating the volume of the medium which is regarded as a parameter of a temperature and a pressure in terms of a volume under the constant temperature and pressure. It is therefore possible to calculate the concentration per unit weight under constant conditions even if the temperature and the pressure are varied at the time of measurement.

A susceptor for holding a semiconductor wafer to be flash-heated by a flash of light emitted from flash lamps is formed of transparent quartz. The susceptor has a backside surface only which is roughened by shot blasting to provide a ground-glass-like surface. When a flash of light is emitted, part of the flash of light emitted from the flash lamps and passing by a peripheral portion of the semiconductor wafer held by the susceptor into the susceptor reaches the ground-glass-like backside surface and is diffusely reflected therefrom. Part of the diffusely reflected light impinges on the peripheral portion of the semiconductor wafer held by the susceptor to thereby heat the low temperature regions which have appeared in the peripheral portion of the semiconductor wafer.

An apparatus and a method both-capable of easily generating diagrams for manufacturing wiring harnesses. Entities of connectors, binding parts and wirings are stored in a hard disk 20. A wiring arrangement diagram is generated with a CPU 22 in accordance with the entities, values and/or characters thus inputted. The wiring arrangement diagram is displayed on a display 6. A desired wiring arrangement can be generated by carrying out amendment and/or modifications of the arrangement thus displayed using a mouse 2 and/or a keyboard 6. A wiring table and an independent wiring harness diagram both considering connection information of each terminal between each of the connectors are generated with the CPU 22 as wiring harness information in accordance with the entities, values and/or characters and so on in the desired wiring arrangement diagram. At that time, a judgement is carried out whether or not the independent wiring harness diagram thus generated complies with a predetermined rule. The wiring table and the independent wiring harness diagram thus generated are outputted from a printer 14.

Method for manufacturing a wiring harness or a substrate for wiring wherein the wiring diagram applied to the substrate is based on the wiring harness information. Entities representing connectors, binding parts, and wiring length information of wirings are input. The wiring arrangement diagram includes lines that correspond to the wirings and do not have a length corresponding to actual length of the wirings. The wiring harness is made using the information including total length of wiring between each of the connectors, harness information generated based on the entities, and the length information of the desired wiring arrangement. Alternatively, the wiring harness information is used to draw a wiring diagram for fixing on the substrate.
