Abstract: PURPOSE:To eliminate the erroneous operation of a circuit or breakdown of an IC by electrically isolating an isolation layer around an island to be possibly at a lower potential than that of the isolation layer from an isolation layer of other elements. CONSTITUTION:An n<+> type buried layer 4 in which antimony is employed as an impurity source is formed including a small signal element part on a p-type epitaxial layer 3. An n<+> type diffused layer 2 is extended into the layer 3 by thermal diffusion of this case, and its top is connected to the layer 4. That is, a p-type epitaxial layer 3a of a section to become a power transistor is isolated from a p-type epitaxial layer 3b of a section to become a small signal circuit. An n-type epitaxial layer 5 is formed, and an element isolation diffused layer and a collector punching n<+> type diffused layer 7 are selectively formed therein. That is, an n-type layer is presented between the power transistor and a lateral p-n-p transistor, its island becomes a power source potential VCC, and even if the island of the power transistor becomes negative potential, it is not affected to the lateral p-n-p, and no erroneous operation of the circuit occurs.

IPC: B67C3/26
Filed: 1981-12-23
Abstract: PURPOSE:To automatically sample a constant amount of oil at an adequate point of time during the operation of a machine, by forming an oil passage which extends from a hydraulic line to an oil sampling bottle through an electromagnetic changeover valve and the valve rod of a bottle holding body, and providing a float valve which chokes the outlet when the specified quantity is attained. CONSTITUTION:When an electromagnetic changeover valve 2 is opened by the control signal from a mechanism 8 which integrates the actual operation time of an operating machine, the pressurized oil from a hydraulic line 1 is introduced into an oil sampling bottle 5 through an intake port 45, a relay port 60, an oil introducing passage 59, and an outlet port 61 successively. When the level of oil in the oil sampling bottle 5 reaches a float valve 64, this float valve starts moving up and when the amount of the oil reaches a certain value, the outlet port 61 is closed. At an adequate point of time, a valve rod 57 is lowered together with the oil sampling bottle 5 by the tensile force of a spring 62 to put the relay port 60 in a shaft hole 58, and thus the pressurized oil is not discharged from the outlet port 61 even if the float valve 64 moves down before the bottle 5 is detached.

Abstract: PURPOSE:To prevent the deterioration of a composite signal by mixing a dummy signal with a transmitter, making it into a secret conversation when a voice signal to an opponent communicating equipment is detected, and stopping the addition of the dummy signal when the signal from the opposite party is detected. CONSTITUTION:When a voice signal from its own station is detected by a transmission detecting device 103, a dummy signal formed by a dummy signal adding device 102 is mixed by a transmitter 101 and sent as a secret conversation signal.

Abstract: PROBLEM TO BE SOLVED: To shorten the rising time of a vibrator. SOLUTION: When a power supply switch 90 is turned on, analog switches 81 and 82 are turned on, and an analog switch 80 is turned off. Thus, a forced exciting/driving circuit 51 supplies the approximate oscillating output pulses of the resonant frequency of a vibrator 30 into an electrode 47 of the vibrator 30 and forcedly excites and drives the vibrator 30 at the time of starting. Thereafter, when the vibrator 30 becomes approximately stable state and the charging voltage of a capacitor 86 reaches the threshold of an inverter 84, the analong switches 81 and 82 are turned off, and the analog switch 80 is turned on. Thus, the output of a self-exciting driving circuit 50 is supplied into the electrode 47 of the vibrator 30, and the vibrator 30 is self-excited and driven.
