Title: Check method for transmission signal converter
Inventor: YOSHIMURA JUNICHI
IPC: H04L1/24
Filed: 1987-10-20
Abstract: PURPOSE:To obtain very high transmission quality by applying phase synchronization when bit comparison between a signal before conversion and a signal decoded by inverse conversion shows dissidence so as to apply bit comparison again thereby preventing erroneous changeover. CONSTITUTION:A digital transmission signal inputted to a transmission signal converter 1 is converted into a prescribed form. The converted signal is inverted into the original form. Then the inverted signal and the signal before the conversion are subjected to phase synchronization. Both the signals subjected to phase synchronization in this way are subjected to bit comparison in the unit of a prescribed period and the coincidence of both the signals is discriminated from the result of bit comparison. If the dissidence of the both is confirmed, the phase synchronization and the comparison are repeated in the succeeding units. If the discrimination of dissidence for a prescribed number of units is obtained consecutively, a fault of the converter 1 is informed to a standby equipment and a changeover device to other line.

Abstract: PROBLEM TO BE SOLVED: To suppress degradation, without exposing a phosphor to gas and prolong the life of a lamp by providing two kinds of phosphor layers arranged without mixing with the outside face of the inner tube of a fluorescent lamp and further adhering film outer tubes to the layers. SOLUTION: This fluorescent lamp is made to have a dual pipe structure such that a phosphor layer 13 is fixed to the outside face of borosilicate glass inner tube 11, and an outer tube 12 of a film visible light transmissive material is adhered to the layer 13. This phosphor layer 13 is applied in a sheet shape and is formed without mixing a phosphor A 21 and a phosphor B 22, so that they may not be superposed. The sizes of the application ranges of these phosphors A and B are determined for such shapes as a rectangle, a dot shape and a stripe shape and about 1mm×0.3mm. The sizes for which color irregularity is not concerned when the fluorescent lamp is seen, are determined.  At this stage, because a positive column and mercury gas exist only in the inner tube 11, the phosphor layer 13 is not exposed to these gases, degradation of the phosphors is suppressed and the life of the lamp can be prolonged.

Abstract: PURPOSE:To obtain inner pressure of an air suction tube and the atmospheric pressure independently by housing a sensor for measuring the pressure in a fuel tank and a sensor for measuring the atmospheric pressure in one case, and providing the atmospheric pressure sensor with a filter for preventing the invasion of solids and liquids. CONSTITUTION:The sensor for detecting pressure of an air suction tube or the like and a sensor for detecting the atmospheric pressure are independently set in a case 20a. A part of the sucked air taken into a suction air route of an engine is guided to a pressure sensor 20 through a nipple 21. A pressure of the sucked air in the suction tube is measured by the suction pressure sensor in the sensor 20. The pressure of the sucked air which is one factor to operate a jetting amount of fuel is required to be corrected by the atmospheric pressure in some cases. Therefore, fresh air is introduced from an air introduction port 24 and the atmospheric pressure is measured by the atmospheric pressure sensor in the sensor 20. Since a filter 25 is set at the introduction port 24, solids or liquids are prevented from entering the inside of the sensor from the outside.

Title: Envelope detector
Inventor: KATOU NOBUYOSHI
IPC: G11B20/06
Filed: 1993-10-22
Abstract: PURPOSE:To protect against a drop-out and to accurately detect it in an envelope detector to be used for a tape recorder, etc. CONSTITUTION:A first counter 21 counts when an input signal exceeds a threshold value. A second counter 22 counts when it does not exceeds the value. When the value of the one of both the counters is a specific range, the other counter is reset, and when the value of the first counter is a specific range or more, it outputs an envelope output. Thus, an instantaneous noise of the input signal is protected by the counter 22, and a drop-out can be protected by the counter 21. Further, resetting of the opposite counter can automatically follow up a change in the input signal to stably detect an envelope.
