Patent JP-H0247874-A (JP)
Title: Manufacture of mos semiconductor device
Inventor: NISHIURA SHINJI
IPC: H01L29/167
Filed: 1988-08-10
Abstract: PURPOSE:To avoid the increase of an ON resistance by a method wherein, at the time of manufacturing a MOS semiconductor device, a low impurity concentration one conductivity type epitaxial layer is formed on a high resistance layer which is provided on the side of the low impurity concentration layer being provided far from the surface on which a gate electrode is provided so as to make the surface layer having a specific resistivity lower than the high resistance layer built up on the high resistance layer. CONSTITUTION:For instance, a high resistance epitaxial layer 13 with a thickness of 30-80mum is built up on an Si substrate 2 doped with Sb and having a specific resistivity of 0.01-0.1OMEGAcm and an epitaxial layer is formed on the high resistance epitaxial layer 13 so as to make its surface part 14 with a thickness of 10-20mum brought into contact with the high resistance layer 13 have a specific resistivity about a half of that of the high resistance layer 13. With this constitution, the increase of a resistance caused by the segregation of Pt, Au or the like into the surface layer induced at the time of lifetime killer diffusion for the reduction of the reverse recovery time of a built-in diode is compensated, the increase of a resistance at the time of a conducting state, i.e., ON resistance, can be avoided and the strength improvement can be realized.

Title: Method and device for detecting interference between moving bodies
Inventor: OZAWA HIROSHI
IPC: G06F17/50
Filed: 1988-08-12
Abstract: PURPOSE:To securely execute detection with satisfactory accuracy at a high speed by using a two-dimensional graphic such as the trihedral chart of respective members, which constitute a three-dimensional object, and detecting the generation of interference in the moving member to the other members. CONSTITUTION:When the position of one member, at least, out of the plural members is moved to the other members, the interference is detected mutually between the respective members. In such a case, since a line element group to be newly crossed with the movement is identified for the line element group of a two-dimensional graphic group, which expresses the plural members, and the line element group of the two-dimensional graphic group which expresses the moving member, the interference is detected between the members. Thus, even when three-dimensional graphic shape data are not generated, the check of the interference can be executed by searching the new crossing of the line group on the two-dimensional graphic such as the trihedral chart, etc. Then, operation is easy, responsibility is improved and the interference check of the high accuracy can be executed.

Abstract: PURPOSE:To accurately detect an address even in the case of feeding film in a reverse direction and to enhance the efficiency of retrieval by reading an address changing mark for reverse feeding showing the address of a frame just before the address changing mark in adjacent to an address changing mark at the time of reverse feeding. CONSTITUTION:A bar code 18A is the address changing mark for reverse feeding, and can be read from the reverse direction discriminatively from blips 14 and 14A. The content of the bar code 18A is the address obtained by adding one to the address of the frame 12b just before the middle blip 14A, that is, which continues in the reverse feeding direction. In the case of feeding the microfilm 10B in the reverse direction, the bar code 18A can be read and has the content of (1, 4). A microfilm reader rewrites the content of a counter to (1, 4) being the content of the bar code 18A. When the next blip 14 is read, one is subtracted from the content of the counter so as to obtain (1, 3), which is set as the address of the frame 12B.

Abstract: PURPOSE:To prevent data from getting inconstant while the data is being transmitted in a communication mode by providing a terminal device which transmits copying data such as the information on the number of copied sheets and the maintenance of a copying machine to a centralized control device which collects data on plural copying machines through a communication line. CONSTITUTION:A processing mode in which processing other than the transmission of data is performed corresponding to the actuation of the corresponding copying machine 10 and the communication mode in which the transmission of data is performed are provided in the terminal device 30. Then, a transmission device 20 which is provided every copying machine 10 in order to transmit the data and a line connection device 3 which transmits the data of the connected transmission device 20 to the centralized control device 5 through the communication line 4 are installed. At the time of requiring the transmission of data, the transmission device 20 can be set in the communication mode only when the corresponding copying machine 10 is not in the midst of a copying action. Therefore, in the communication mode, which is not the processing mode, the change of the data is prevented, which occurs because the copying data such as the number of the copied sheets is written due to copying. Thus, the data is prevented from getting inconstant while the data is being transmitted in the communication mode.
