Title: Dc ground detector of photovoltaic power generation system
Inventor: YUGOU MASAKI
IPC: H02J3/38
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To avoid an electric shock caused by a leakage current, etc., by a method wherein, a DC ground judging means which judges that a DC ground of a solar battery exists and stops the operation of an inverter and an output reducing means which reduces an AC output from the inverter when a detection level by a ground detecting means is higher than a certain level are provided. SOLUTION: If the detection level of a ground detecting means 8 is higher that a certain value, the AC output of an inverter 2 is suppressed by the output reducing means of an inverter control unit 5 and, when the detection level of the ground detecting means 8 is lower than a second level, a fixed output operation is performed. Therefore, when a temporary leakage current is produced in a rainy state, etc., the operation of the inverter 2 is not stopped instantly by the mistaken judgement of a DC ground. Further, if a leakage current is not reduced below a 2nd level in spite of that the output of the inverter is suppressed to the lowest output value with which the system linkage is possible, the operation of the inverter is stopped, so that an electric shock caused by a leakage current, etc., can be avoided.

Title: Ink jet recording apparatus
Inventor: OHASHI TETSUHIRO
IPC: H04N1/401
Filed: 1995-04-11
Abstract: PURPOSE: To reduce a count of openings and obtain a highly rigid housing, by using a common opening for the purpose of attaching/detaching a recording head cartridge or scanner head to a carrier and for the purpose of cleaning a white reference for the scanner head. CONSTITUTION: An attaching/detaching position of a recording head cartridge 1 or scanner head to a carrier 2 is set in the vicinity of a white reference. A printer opening 406 is formed in a housing storing a recording apparatus. The printer opening 406 works both as an opening through which the recording head cartridge or scanner head is attached/detached to the carrier and as an opening required when the white reference is cleaned. Accordingly, since separate openings for cleaning of the white reference and for exchanging of the recording head cartridge or scanner head are not necessary, the housing of the recording apparatus becomes highly rigid.

CONSTITUTION:When pressurized air is introduced into an air chamber 9 from a hose 20, the air is diffused in the vicinity of water surface from pumping cylinders 7 as shown in the arrows 31, 32 and returned in the water bottom part shown as the arrows 33, 31. In such a way, the water plenty in dissolved oxygen amount in the water surface is transferred to the water bottom and mixed with the water little in dissolved oxygen. The whole amount of dissolved oxygen is increased. Further when a treating agent is supplied through hoses 36 from a powerboat 1 and injected into conductors 41 provided in the respective pumping cylinders 7, the treating agent is mixed with lifted water, diffused and allowed to react with the aimed substance. By this method, since self-sustaining properties are imparted to circulation of lifted water water purifying treatment is performed for a prescribed time in the prescribed water area of the wide water area. Then water purification is successively enabled by transferring the water area only in the necessary distance by the powerboat 1. The aim of water purifying treatment is efficiently achieved even in the wide water area.

Abstract: PURPOSE:To detect an accident occurred in any point throughout the overall length of an aerial transmission line by measuring a temperature distribution in the lengthwise direction of an overhead ground line from a backward scattered beam distribution of an optical fiber on the conjugated overhead ground line of optical fiber. CONSTITUTION:A measuring device 15 for temperature distribution is connected to one end of the conjugated overhead ground line 3 of optical fiber through the optical fiber 8, and a Raman scattering beam pulse generated in the optical fiber of the overhead ground line 3 by a laser pulse beam which is entered from the device 15 is detected by a time division. Since this pulse size depends on the temperature, the temperature distribution corresponding to a current distribution throughout the overall length of overhead ground line 3 can be obtained in the device 15. Temperature distribution signals measured in the device 15 are accumulated in a signal processing device 17. When a trip signal corresponding to the fault is generated, the value of the difference between the temperature distribution signal measured one time before the time receiving a trigger signal which is generated in a trigger signal generator 16 and the temperature distribution signal at the time immediately after receiving the trigger signal is calculated by the device 17 to obtain a distribution of the temperature rise values, thereby a point showing highest temperature rise is decided as the faulty point.
