IPC: G05F3/26
Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To improve the temperature characteristics of a reference voltage by correcting the temperature characteristics of an output voltage from a reference voltage circuit through a temperature correcting circuit. SOLUTION: This circuit is composed of a reference voltage circuit 101 and a temperature correcting circuit 102 for correcting the temperature dependency of an output voltage Vout from the reference voltage circuit 101. Concerning the temperature correcting circuit 102, the back gate of an n-channel enhancement type MOS transistor 111 is grounded or connected to the source of the transistor 111. When this newly added temperature correcting circuit 102 detects the temperature of a semiconductor integrated circuit(IC) and the temperature of the semiconductor IC is high, a current is injected from the temperature correcting circuit 102 to the conventional reference voltage circuit 101. Thus, the temperature characteristics of the reference voltage is corrected and the reference voltage of satisfactory temperature characteristics can be provided.  Namely, by increasing the reference voltage at a high temperature, the difference between the reference voltage at a medium temperature and the reference voltage at the high temperature is reduced so that the temperature characteristics of the reference voltage is improved.

Filed: 1986-12-17
Abstract: PURPOSE:To obtain a mixed output in which the sum of signal is not 100% while the excellent operating characteristic with the sum of signal of 100% at fader interlocking is obtained by using a fader separation detection circuit to switch a control signal to a video mixing circuit and a gain control circuit at fader interlocking and separation. CONSTITUTION:In case of the fader interlocking, a voltage C is supplied to a control input 4 of a video mixing circuit 3 by a fader separation detecting circuit 13 and a constant voltage 1 is supplied to the control input 6 of the gain control circuit 5, so that the gain control circuit 5 is omitted equivalently and the circuit becomes the one fader system mixing circuit by the video mixing circuit 3. In separating the fader, the signal supplied to input terminals 1, 2, is mixed in the ratio of C/(C+D) and D/(C+D) respectively by the video mixing circuit 3 and amplified to be multiplied by (C+D) in the gain control circuit. Accordingly, the output terminal 7 can obtain the signal mixed by following multitude rate that the signal multitude supplied to the input terminal 1 is C/(C+D)X(C+D)=C and the signal multitude supplied to the input terminal 2 is D/(C+D)X(C+D)=D. This means that the two video signal inputs are controlled independently and the mixing whose sum is not 100% is attained.

Filed: 1992-10-15
Abstract: PURPOSE:To facilitate the incorporation and working of a dovetaile-shaped guide structure by making the maximum width of the male side of the dovetail structure having a dovetail angle smaller than the minimum width of the female side. CONSTITUTION:A gib 4 consists of a pair of members tapered longitudinally to be inserted into a gap between inclined slide surfaces from both longitudinal ends of dovetail and dovetail groove to close the gap, so that the surface of a table side making contact with the dovetail slide surface forms as a whole a plane. The maximum width (a) of the male side of the dovetail groove is made smaller than the minimum width (b) of the female side of the dovetail groove. Thus, while a dovetail-shaped slide guide structure is employed, the dovetail of the table 2 side can be incorporated in the dovetail groove of a saddle from the vertical direction. Accordingly in scraping the respective slide surfaces 3 and fitting a slide surface 3, the incorporation and disassembly of members are facilitated and thereby the working of these surfaces is facilitated. Particularly, the effect is remarkable when the table 2 is large and heavy.
