Title: Underpower relaying device
Inventor: KATO HITOSHI
IPC: H02J3/38
Filed: 1992-10-21
Abstract: PURPOSE:To prevent the inessential trip of a system circuit breaker by a method wherein, when a purchased electric power value is an underpower settling value or lower, it is judged to be underpower on the power purchase side and the system circuit breaker is tripped. CONSTITUTION:When a purchased power supply 1 and a non-utility generation 2 are in a parallel operation state, the secondary-side voltage PT1 of a potential transformer 11 and a secondary-side load currents CT11 to CT1n, CT21 to CT2n of instrument current transformers 13 to 16 are input to an underpower relaying device 12, and load electric power is detected. When the load electric power is 0 or higher, purchased-supply electric power is detected by an electric current CT1 and the voltage PT1 on the secondary side of the instrument current transformer 10 a the potential transformer 11. When the purchased- supply electric power is an underpower settling value of lower, it is judged to be underpower on the power purchase side, and a trip signal is output to a system-splitting-point circuit breaker CB2 after a definite time. Thereby, it is possible to prevent an inessential trip due to the detection of underpower.

IPC: G02F1/133
Filed: 1990-10-23
Abstract: PURPOSE:To correctly detect the displacement of a liquid crystal light bulb by providing a light transmission section and a light cutoff section on the liquid crystal light bulb. CONSTITUTION:The laser beam from a laser light source 1 is continuously outputted by a polarizing piece for each dot, and it is swept by a scanning optical system 2 for dots of a liquid crystal light bulb 3. When the swept laser beam is radiated to a light transmission section, the laser beam is fed to an optical fiber cable 62 arranged oppositely to the transmission section, and it is converted into an electric signal by a measuring device 5 and applied to a threshold value detecting circuit 55. The circuit 55 interrupts an arithmetic circuit 57 at the preset threshold value level. The circuit 57 records the scanning state of the optical system 2, i.e., the radiation position of the laser beam on the face of the bulb 3. The actual radiation position when the circuit 55 interrupts is known, and it is compared with the primarily rightful radiation position stored in advance. Correct displacement can be detected without affecting the normal projection.
