Title: Dc level shifting circuit
IPC: H04N5/18
Filed: 1992-03-31
Abstract: PURPOSE:To eliminate a temperature dependency, and also, to reduce an input dynamic range of a pre-amplifying part and a main amplifying part by feeding back a differential output of a DC level and a reference level of an output signal of the main amplifier to the pre-amplifier and clamping an output signal level. CONSTITUTION:A video signal, etc., amplified by a pre-amplifier part 3 are subjected to power amplification by a main amplifier part 7, and a DC level is shifted. A differential output from a differential amplifier 11 of a difference between the DC level of an output signal of this amplifier 7, and a reference level is fed back to the amplifier part 3, a bias voltage of the amplifier part 3 is clamped to a prescribed voltage, a DC level of an output V3 of the amplifier 7 is controlled so as to become constant, and also, a temperature dependence characteristic of the DC level is eliminated. Also, input/output dynamic ranges of the pre-amplifier parts 3, 5, and an output dynamic range of the amplifier part 7 can be reduced extending over a wide range, power consumption is decreased and output amplitude can be obtained as large as possible.

Title: Single chip microcomputer
Inventor: OKAMOTO WATARU
IPC: G06F15/78
Filed: 1989-04-25
Abstract: PURPOSE:To secure a high-grade fail-safe property and the security of a system by adding a simple stack error detecting circuit to a CPU to automatically detect the abnormality of a stack action and also to perform a proper after- process via the CPU. CONSTITUTION:A stack error detecting circuit 17 is added to a CPU 30 to monitor the coincidence between the byte numbers of the push data and the pop data and to output an error signal at occurrence of a stack error. When the abnormality of a stack action is produced, a stack error detecting signal 20 is outputted from the circuit 17 and the CPU 30 performs an error process via an interruption control part 9. At the same time, a control part 5 outputs an increase/decrease signal 14 and a clear signal 18 during the execution of a pop instruction. Thus it is possible to improve the fail-safe property and the security of a system.

Title: Manufacture of trench insulating structure inside semiconductor board
Inventor: EFU JIEI ROBINSON
IPC: H01L21/74
Filed: 1990-04-24
Abstract: PURPOSE: To prevent growth of pseudo-epitaxial silicon by depositing an oxide on a semiconductor substrate having a trench and increasing the thickness of oxide at the upper corner part of trench opening thereby growing a thermal oxide layer. CONSTITUTION: When an opening is etched to a depth of at least about 10μm and an oxide 13 is deposited in the trench and on a mask oxide 11, deposition of the oxide 13 on the side wall of the trench 12 is decreased by the pointed end part of the oxide 13 at the opening. A thermal oxide layer 14 is grown beneath the deposited oxide layer 13 which is then planarized on the surface. Consequently, only a small quantity of oxides 13, 14 are grown on the surface of a wafer 10 and beneath the region of the oxide 11. Furthermore, density of the deposited oxide 13 is increased. Since a sufficient quantity of oxide 13 is left after etching at the upper corner part of the trench 12, growth of pseudo- epitaxial silicon is prevented during selective epitaxial growth in a deep trench.

Abstract: PURPOSE:To accurately detect the occurrence of a dew condensation state in a cylinder and a tape guiding member, etc., by providing plural dew condensation detecting elements which detect the humidity state in an area including the traveling system of a magnetic tape. CONSTITUTION:Two dew condensation detecting elements 2a and 2b are provided in a specified range including the traveling system of the magnetic tape 8 in a VTR part 7.

When it is dried inside the VTR part 7, thereafter, the element 2a detects the resolution of the dew condensation first and the element 2b detects the resolution of the dew condensation as the dew condensation of the cylinder 4 is resolved. Thus, the point of time when the dew condensation starts to occur inside the VTR part 7 is detected by the detection output from the element 2a and the point of time when the dew condensation is resolved is detected by the detection output from the element 2b.
