Title: Method of operation analysis for semiconductor device and apparatus used therefor
Inventor: KURATA MAMORU
IPC: H01L21/66
Filed: 1990-07-16
Abstract: PURPOSE:To obtain a method for analyzing the operation of a semiconductor device by determining the arrangement of dividing points in the semiconductor device, imparting the adequate space position dependency to sensitivity coefficients, integrating the specified expressions with time until the steady state is obtained, obtaining the solution of simultaneous equations, and thereby obtaining the solution of the specified simultaneous equations without applying matrix solution. CONSTITUTION:The series of simultaneous equations comprising the transport equation and the Poisson equation of electrons and holes in a semiconductor device modeling are analyzed with a computer. In this method, the series of the simultaneous equations are substituted with equations dp/dt=-lambdapfp, dn/dt =-lambdanLfn and dphi/dt = -lambdaphifphi. The integration of the equations is performed with time until the steady state is obtained. Thus the solutions of the steady-state equations fp=0, fn=0 and fphi=0 are obtained. At this time, the arrangement of the dividing points (M, N) of the semiconductor device are determined. Adequare space position dependency which agrees with the physical characteristics of the semiconductor device is imparted to sensitivity coefficients lambdap, lambdan and lambdatheta. Intagration of the specified equations which are converted from the above described equations is performed with time until the steady state is obtained. Thus the solutions of the series of above described simultaneous equations are obtained.

Title: Ventilating device for housing
Inventor: AIZAWA HIDEHARU
IPC: F24F3/00
Filed: 1989-07-19
Abstract: PURPOSE:To perform efficient regulation of the temperature of a housing by a method wherein a ventilating space running from an underfloor place to a ceiling is formed internally of the wall of the housing, and a heat exchange pipe for intercommunicating the underfloor and the outside and heat- exchangeable of an inner air temperature with geothermal energy is embedded in a ground. CONSTITUTION:A ventilating space 5 running from an underfloor place 3 to an attic 4 is formed internally of a heat insulating material 13 of at least a wall 2 of a housing H. Meanwhile, a heat exchange pipe 6 is embedded in a ground G. The heat exchange pipe 6 heat exchanges geothermal energy with an internal air temperature through utilization of a material having excellent thermal conductivity. Since the temperature of the ground G is kept at a comparatively constant temperature of 10-15 deg.C regardless of a winter and a summer season, an internal air temperature is regulated naturally. Meanwhile, a blast fan 7 is mounted in an attic 4, and the ventilating space 5 is communicated with the attic 4. This constitution prevents reduction of an indoor temperature by means of hot air in the attic 4 during a winter season and suppresses the increase of an indoor temperature by means of cold air during a summer season.

Filed: 1993-06-30
Abstract: PURPOSE:To prevent the wear in a ROM card edge by inserting the ROM card edge of a game cassette into a connector of a cassette protector, and further inserting an edge part into a game machine main body and transmitting a signal. CONSTITUTION:The ROM card edge of the game cassette is inserted into the connector 31 of the cassette protector 3, and further, the edge part 32a is inserted into the port of the game machine main body. Thus, a program software signal recorded on the game cassette is transmitted to a communication substrate 32, and further, is transmitted to the game machine main body through the edge part 32a. Then, since the exchange and the attaching/detaching to the game machine main body is performed so that the protector 3 in the state of loading the game cassette is exchanged and attached/detached, no ROM card edge part of the cassette is weared even when the exchange and the attaching/detaching are performed frequently. Thus, the occurrence of a starting defect and a program operation defect due to the wear in the ROM card edge are prevented.
