IPC: H02M7/48
Filed: 1999-11-29
Abstract: PROBLEM TO BE SOLVED: To perform malfunction detection such as the life detection of a lamp while maintaining low cost without need for the use of a highly precise detecting means. SOLUTION: A lighting circuit 1 supplies electric power for lighting to a discharge lamp La. The presence of malfunction in the discharge lamp La is detected by a detecting means DM and, in case that some malfunction occurs, the output of the lighting circuit 1 is limited. The output of the lighting circuit 1 is variable, and in detecting the presence of malfunction in the discharge lamp La, it shifts to a detecting level different from that in the case of ordinary lighting for a short period.

Title: Abnormal vibration detector
Inventor: MARUKI TOSHIMITSU
IPC: G01L3/00
Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To reliably detect abnormal vibration for various operating conditions by detecting that axial torque vibration exceeds first and second set levels respectively and remains as it is for a predetermined time. SOLUTION: When an axial torque detection signalτ A (5 to 12Hz) is passed through a 1-Hz filter, a constant average axial torque signalτ P is obtained, and a deviation detection part 16 detects deviation between the detection signalτ A and the average axial torque signalτ P, that is Δτ A-Δτ P. If each vibration exceeds a first set level, comparators 18, 21 are turned ON, and off-delay timers 19, 22 are also turned ON. Therefore, an AND circuit 23 outputs 1, and an on-delay timer 24 determines abnormal vibration if this state continues for 10 seconds. In addition, when vibration higher than a high level of second setting continues for 3 seconds, an on-delay timer 36 determines abnormal vibration.  Further time since the detection signal exceeds the first level until it exceeds the second level is less than 2 seconds, an AND circuit 35 outputs 1, and suddenly increasing abnormal vibration is determined.

Filed: 1994-12-20
Abstract: PURPOSE: To easily obtain a pilot flame of necessary amount by providing a vent hole at the side of a cylinder having upper and lower openings and formed of a metal plate, and installing it on a grill or metal gauze. CONSTITUTION: A cylinder 1 having upper and lower openings 2 is formed of a metal plate. A vent hole 3 is provided at the side of the cylinder 1. A solid igniting agent 5 is placed on the grill or a metal gauze 4, ignited, and covered with the cylinder 1. Then, charcoal 6 is thrown from the opening 2. After the charcoal 6 is ignited, the cylinder 1 is raised, and removed. The temperature rise in the cylinder 1 due to the agent 5 and the charcoal which start to burn generates the rising air flow in the cylinder 1, and the introducing air flow from the opening 2 expedites the burning of the lower charcoal. It further raises the inner temperature to increase the introduced air, thereby expediting the burning of the charcoal. A pilot flame formed in the cylinder 1 by the high temperature and the supply of sufficient oxygen of the conditions of the pilot flame is increased, the burning of the lower charcoal is expedited. The high temperature and the supply of sufficient oxygen of the conditions of the pilot flame are formed in the cylinder 1, thereby obtaining the ignited charcoal.

IPC: B29C48/92
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To obtain a measuring method in which the distortion of a transparent resin sheet or the like can be discriminated visually and easily by means of a flow mark by a method wherein a geometrical pattern is imaged, through the transparent resin sheet or the like, by a camera which is arranged in such a way that an angle formed by the optical axis of a lens and by the face of the transparent resin sheet or the like becomes a specific angle. SOLUTION: A transparent resin sheet or the like 1 is piled up on a geometrical pattern 2 which is drawn on a plane. In addition, a camera 3 is arranged in such a way that an angle α formed by the optical axis of the camera 3 and by the sheet or the like 1 is at 10 to 80 deg.. When the angle α is less than 10 deg., the disorder of the outline of the pattern is extreme, but the contrast of the pattern is lowered as a whole. When the angle exceeds 80 deg., the contrast is sufficient, but the disorder of the outline cannot be amplified. The pattern 2 is photographed by the camera 3 through the sheet or the like 1. Thereby, the distortion of the sheet or the like 1 due to a flow mark on the sheet or the like 1 is reflected on the distortion of the outline of the pattern 2, and the dislocation can be discriminated visually and easily.
