IPC: H04B1/74
Filed: 1986-12-15
Abstract: PURPOSE:To attain an efficient line setting by transmitting the selection request of a satellite line to other exchange stations connecting to an earth station from an exchange station detecting the disabled operation of an earth line and allowing each exchange station connecting to the earth station to select definitely the satellite line based on the information. CONSTITUTION:The fault of an earth transmission line is informed from the earth station 33 connected to the exchange station 14 to all earth stations in the communication network via a satellite line 50. Moreover, each earth station the fault information to the connected exchange station and if a communication request from a terminal 21 to a terminal 22 exists, the exchange station 11 uses s dial number from the transmitting terminal equipment 21 to discriminate the exchange station 14 accommodating the incoming side terminal equipment 22 and the disabled ground line 70 reaching the exchange station 14 is recognized.

Title: Liquid crystal projector
Inventor: SASAKI YOSHIHIRO
IPC: G02F1/13
Filed: 1993-11-26
Abstract: PURPOSE:To obtain a cooling structure of a liquid crystal projector having high accuracy with a simple constitution by holding liquid crystal panels within the same hermetically closed space and arranging cooling means within the same space. CONSTITUTION:A first cabinet 1 completely hermetically closes an optical system including the liquid crystal panel 3 to shut off the dust, etc., infiltrating from the outside. Air cooled by an electronic cooler 8 is introduced through an upper duct 10 by a fan 9 to three sheets of the liquid crystal panels 3, 3, 3 to cool these panels. The air warmed up by passing the respective panels 3, 3, 3 is introduced through a lower duct 11 again into the cooler 8 and is cooled. As a result, the sticking of the small dust, etc., on the panels 3 or dichroic mirror 25 of the liquid crystal projector does not arise and the degradation in the luminance of the images displayed on a screen does not arise any more. Since the need for an air filter is eliminated, the degradation in the cooling functions occurring due to the pass rate of air by the dust sticking to the air filter does not arise either.

Filed: 1997-10-29
Abstract: PROBLEM TO BE SOLVED: To enable the stable coating of a multi-color pattern of high coat quality and excellent color tone to an object to be coated for a long time. SOLUTION: The coating device PS for coating a multi-color pattern to an object 1 to be coated has coating circulation machines 13, 21 installed in coating supply passageways 9, 18, respectively, which run from coating storage tanks 7, 16 to the two-pack concentric coating gun 3 of a coating machine P.

Title: Direct-current power supply unit
Inventor: ASO SHINJI
IPC: H02M3/28
Filed: 1999-10-19
Abstract: PROBLEM TO BE SOLVED: To prevent back flow of current and damage to field-effect transistors. SOLUTION: When a back flow of current occurs, the potential at the drain terminal of a field-effect transistor Q1 becomes higher than the potential at the source terminal. At this time, the voltage applied to between the base and emitter of a bipolar transistor Q2 becomes higher than the voltage applied to a bipolar transistor Q3, and base current is supplied to the bipolar transistor Q2. Thus, the bipolar transistor Q2 becomes conducting, and the bipolar transistor Q3 becomes non-conducting. Thus, the gate terminal and the source terminal of the field-effect transistor Q1 are short-circuited with each other to interrupt gate voltage, in this way, and thereby the field-effect transistor Q1 becomes non-conducting. As a result, a back flow of current is prevented, and damages to the field-effect transistors are avoided.
