Title: Semiconductor device
Inventor: SAWAZAKI NORIYUKI
IPC: H01L23/40
Filed: 1993-12-28
Abstract: PURPOSE:To prevent dislocation at the time of attaching a semiconductor device with a screw by engaging a recess provided at either of a semiconductor and a heat radiation member with a projection provided at the other, and positioning the semiconductor device and the heat radiation member, or the semiconductor device, an insulating conductive member and the heat radiation member. CONSTITUTION:An insulating conductive spacer 3 is arranged along bosses 2a and 2e, and a semiconductor device 1 sealed with resin is placed so that the recesses 1f and 1g at the rear of the semiconductor device 1 sealed with resin may engage with the bosses 2g and 2h of a heat sink 2. Next, the screw pierces the mounting hole 1e of the semiconductor device 1 sealed with resin and the aperture 3a of an insulating conductive spacer 3, and screws in the screw groove 2f of the heat sink 2. At that time, even if stress in rotational direction works on the semiconductor device 1 sealed with resin, it is positioned already with the recesses 1f and 1g and the bosses 2g and 2f, so it never causes dislocation. Accordingly, the semiconductor device 1 sealed with resin can be fixed accurately to the heat sink 2.

Abstract: PURPOSE:To expand an area by providing a table storing the relation between a subscriber number and a transfer destination in a trunk exchange system and providing a table storing the relation between a dial and an ID number for each slave set in a master set. CONSTITUTION:Suppose that a slave set 3Aa makes position registration in the area of a connector 2Lm not at a home position, then a master set 1L checks a table 21L to confirms that the slave set 3Aa is a slave set whose home position is not itself but the master set 1A.

The master set 1A updates a connector corresponding to the slave set 3Aa in a table 21A into 'none', the master set 1 into '1L' and its transfer destination into 'DNLn+1'. When a call comes by the dial number DNLn+1, the master set 1L uses the dial number DNLn+1 as a key to retrieve the table 21L, calls a slave set 3Aa through the connector 2Lm as a result to make connection with the reply of the slave set.

IPC: C21C7/00
Filed: 1989-12-28
Abstract: PURPOSE:To dynamically estimate the C in the molten steel to be treated by determining the content of C during the course of a treatment by an initial decarburization reaction rate from a nitrogen leak rate and estimating the subsequent change in the contained C with the lapse of time in the analysis of exhaust gases during the stage for decarburizing the molten steel to an extra-low carbon region by the vacuum decarburization treatment. CONSTITUTION:Since the reaction rate constant of the primary reaction can be estimated from the nitrogen leak rate while the change of [C] during the vacuum treatment is governed with the primary reaction rate taking the delay of a vacuum evacuation system into consideration, the exhaust gases generated during the decarburization treatment are analyzed and the nitrogen leak is determined from the concn. ratio of a standard gas and N2 and the flow rate of the standard gas of a known flow rate at the time of producing the dead soft steel by the vacuum degassing of the molten steel by an RH method or DH method. The decarburization reaction rate in the initial period of the reaction is calculated from this nitrogen leak rate and the [C] during the course of the decarburization treatment is estimated. The subsequent change in [C] by lapse of time is estimated by the decarburization quantity determined from the concn. ratio of the standard gas and CO and CO2 and the flow rate of the standard gas, by which the [C] in the molten steel under the decarburization treatment is estimated with high accuracy.

Title: Measuring method for adhesion force of thin film
Inventor: HANAOKA HIROKO
IPC: G01N3/20
Filed: 1997-12-09
Abstract: PROBLEM TO BE SOLVED: To obtain a measuring method in which the adhesion force with reference to a substrate of a thin film can be measured simply with high accuracy and quantitatively by gradually bending a complex which is composed of the substrate and of the thin film, using a stress which is applied to the thin film at a time when the thin film is stripped from the substrate as a parameter, and measuring the critical adhesion force of the thin film. SOLUTION: A stress σ which is applied to a thin film 2 on a substrate 1 by a bending operation can be computed generally by Stoney's expression on the basis of the balance between a force and a moment in a very small part on the substrate 1. When the cross section of the deformed substrate 1 can be regarded as an arc, an expression of σ=(E.b<2> .δ)/ 3.(1-ν).d.l<2> } is established, where E represents Young's modulus of the substrate 1, (b) represents the thickness of the substrate 1, δ represents the displacement amount of the substrate 1, ν represents the Poisson ratio of the substrate 1, (d) represents the thickness of the thin film 2 and (l) represents the length of the substrate 1. The stress which is computed by the expression or the function of the stress σis regarded as the adhesion force with reference to the substrate 1 of the thin film 2.
