Title: Impurity density measuring method
Inventor: KATOU TOSHIROU
IPC: H01L21/66
Filed: 1978-08-22
Abstract: PURPOSE: To measure an impurity density accurately by measuring a C-V charac- teristic under a state where an opposite-conductive type second semiconductor layer is formed on the surface of the first semiconductor layer, where the impurity density should be measure, and a PN junction is formed on the surface of the second layer.  
     CONSTITUTION: N -  epitaxial layer 12 is grown in vapour phase on the surface of N + -type semiconductor substrate 11, and further, P + -type epitaxial layer 13 is grown in vapour phase on the surface of N - -type epitaxial layer 12. PN junction 14 is formed on the surface of N - -type epitaxial layer 12. PN junction 14 is formed on the surface of N - -type epitaxial layer 12 by vapour-phase growth of P + -type epitaxial layer 13. Next, after forming aperture 16, contact needle 17 is brought into contact with the surface of individual epitaxial layer 13, and a voltage by which PN junction 14 is biased backward is applied across epitaxial layer 13 and semiconductor substrate 11, thereby measuring the C-V characteristic between both. On a basis of this measurment result, the impurity density of epitaxial layer 12 is obtained.

Filed: 1992-04-22
Abstract: PURPOSE:To reduce change of dot area with respect to speed difference of vertical scanning by providing an image formation means for forming dots with scanning lines, as a start line or end line, to be scanned by light point positioned in the lowest stream in the vertical scanning direction among light point groups. CONSTITUTION:By making a scanning order to be I=n-1 or I=n+l, a cluster is generated at a simple cycle. Dots are formed synchronizing with this cluster so as to reduce fluctuation of a dot area. Concretely, dots 10 are formed with scanning lines, as a start line, to be scanned by a laser beam L4 located at the lowest end, i.e., lowest stream in the vertical scanning direction among a plurality of laser beams L1-L4 to be scanned at a time. The density of a dot image is expressed by the number of picture elements which constitute the dots 10. A single dot image is formed in a single cluster 11. As intervals among the scanning lines in one cluster are the same, intervals among the picture elements will be equalized. Accordingly, the dot area does not change.

Filed: 1986-05-06
Abstract: PURPOSE:To obtain a facsimile equipment having a telephone/facsimile automatic switching device provided with an automatic answering telephone mechanism by providing a telephone set on the callee side with a recording means which can record an answering message. CONSTITUTION:A controller 5 is provided with recording means such as IC recording which can record the answering message as the telephone set. Namely, said controller 5 detects a bell sound of 16Hz from the calling side, automatically attains a call state, and transmits the previously recorded message from the callee side to the calling side. If the calling side is a voiceless terminal, that is, a facsimile, a tone signal (CNG signal) of 1100Hz for 0.5sec is intermittently originated, leaving a 3-sec break period. As a result the controller 5 detects the signal, connects the line with the facsimile and simultaneously starts the facsimile through a photocoupler (not illustrated in figure). On the other hand, if the calling side is a voice terminal, namely, a telephone call, it becomes a communication circuit and can be used as a normal telephone set. When the callee is absent, the answering message of the absence which is previously recorded in the controller 5 is suitably repeated.

Abstract: PURPOSE:To prevent generation of ghost, even in repeated printing, and enable clear printing, by enabling a surface of a porous structure to be releasably adhered to a receptor. CONSTITUTION:An ink-maintaining layer 3 is provided on a base 2. The layer 3 has a heat-fusible colored ink 6 contained in pores 5 of a porous structure 4, and a surface 4a of the structure 4 is releasably adhered to a receptor at the time of thermal transfer.
