Title: Short-circuit directional relay
Inventor: MITO KAZUMA
IPC: H02H3/38
Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To improve trouble detection precision by changing operating characteristics by inputting a setting from the outside, converting a secondary analog value into a digital data for determining a phase difference between power system current and power system voltage, and attaining optimum operation measurement in response to characteristic values of a power system and conditions in the event of a short-circuit trouble. SOLUTION: In a short-circuit directional relay 4 detecting a short-circuit trouble on a transmission line 3, the direction indicated in a short-circuit trouble detected section 8 is taken as a short-circuit trouble direction. If a short-circuit trouble is detected at a trouble position 9, it is regarded as a short-circuit trouble in the short-circuit trouble detected section 8 according to a phase difference between voltage inputted through a voltage transformer 6 and current inputted through a current transformer 5 and the magnitude of input current, so that a protective output is conducted for a breaker 7.  If a short-circuit trouble is detected at a fault position 10, it is regarded as a trouble outside the short- circuit trouble detected section 8 according to a phase difference between voltage and current and the magnitude of input current, so that no protective output is conducted. It is thus possible to improve trouble detection precision.

Title: Scanning optical system
Inventor: UEMURA HARUO
IPC: G02B26/12
Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To provide a scanning optical system constituted so that the bending of a scanning line by plural light beams is suppressed and an accurate scanning action can be executed. SOLUTION: A cylindrical lens 50 is formed so that the incident surface IS1 at the center (incident angle β=0 deg.) is provided with a semi-circular cross section whose radius is (r0) but the radius of the curvature (r) of the incident surface IS2 whose cross section is vertical at the position of the incident angle βis r=r0.(1/cos β)m. Thus, when a focal distance by the incident angle β=0 deg. is defined as (f0), the focal distance (f) at the vertical cross section at the position of the incident angle βsatisfies the expression of f=f0.(1/cos β)m. Due to that, since the effective focal distance at the cross section at the position of the angle β becomes almost uniform in a scanning direction (Y direction), the bending of the scanning line is suppressed and the accurate scanning action can be executed with a multibeam scanning.
