Abstract: PURPOSE:To detect the defect on the inner surface of the socket of an iron pipe having the complicated shape automatically and efficiently by moving an image sensing device and a lighting device in conformity with the shape of the inner surface of the socket of the iron pipe, partially picking up the image of the inner surface of the socket, and processing the image. CONSTITUTION:A microscope 6 is moved along the inner surface of a socket 1a. The light is emitted from an optical fiber 6b on the local part of the inner surface of the socket 1a at the specified distance and angle. The image of the local part is expanded and picked up. The emitting angle of the light from the optical fiber 6b and the image sensing angle of a camera 6a are different. Therefore, when there are a defective recess part X and a defective protruding part Y, the corresponding shadow parts X and Y are formed. The expanded image of the local part which is captured as the shadow is received in an image processing device 23. In the device 23, the luminance of each picture element of the expanded image is compared with a threshold value, and binary coding is performed. When the area of the black-color side corresponding to the shadow parts X and Y is larger than the preset value, it is judged that there is a defect on the inner surface of the socket 1a with an operating device 24.

Title: Electrostatic latent image developing toner
Inventor: YASUNO MASAHIRO
IPC: G03G9/08
Filed: 1990-11-08
Abstract: PURPOSE:To stably keep fluidity high for a long time by attaching and/or fixing fluidizing agent locally on the dense surface of toner. CONSTITUTION:When fluidizing agent which has been locally fixed on the dense surface of toner, is to be released by means of stirring, toner fluidity due to change in density at the locally dense fixing section is not substantially affected, the amount of fluidizing agent which is decreased because of releasing or imbedding in a place other than the aforesaid fixing section, is supplemented by the dense fixing section. This thereby allows the amount of fluidizing agent to be kept constant without depending on stirring time. The fluidity of toner thereby will never be lowered even if it is stirred for a long time. When a position which keeps fluidizing agent high in density, is locally defined, the deterioration of the environmental dependability of the electric charging property of toner due to an excessive addition of fluidizing agent can thereby be minimized.

Filed: 1993-12-01
Abstract: PURPOSE:To reduce the cost simplifying the circuit in a squib inspection circuit in an air bag system of a vehicle. CONSTITUTION:A microcomputer 1 switches on a transistor TR1. Then, the test current I flows from a DC/DC converter 2 to a resistor R4, a squib SQ, the transistor TR1, and a resistor R3. The voltage V2 at the upper end of the resistor R3 is obtained, and if the obtained value is larger than the prescribed value, a judgement is made that the test current is excessive, and the prescribed error processing is executed. The current value of the test current I is calculated from the value of V2 and the resistance of the resistor R3. The microcomputer 1 obtains the voltage at both ends of the squib SQ through a differential amplifier DAMP, and the resistance of the squib is obtained based on the voltage at both ends and the test current. The driving voltage V1 of TR1 is adjusted by R1, R2, and the current is limited by making TR1 switch-off when the generated voltage V2 by the current flowing in R3 becomes large.
