Title: Center electrode of spark plug
Inventor: TANAKA MINORU
IPC: H01T13/20
Filed: 1995-05-16
Abstract: PURPOSE: To ensure sufficient strength and impact resistance by a glass sealing material. CONSTITUTION: When the diameter d1 of a collar part 32 and the diameter d2 of a head part 33 in a center electrode 3 satisfy 0<=d1-d2<=1mm, a collar head length (h) from the lower end of the collar part 32 to the upper end of the head part 33 is set within +25% of (d0-d1)×5 to the inside diameter d0 of the large diameter hole 24 of an insulator 2. The head part 33 has a recessed part 34 on the top surface. Since the lengths of the collar part 32 and the head part 33 are ensured to some degree without being too short, and not too long, a glass sealing material 4 is surely carried to the side surfaces of the head part 33 and the collar part 32 to provide a sticking strength with the central electrode 3. Since the recessed part 34 is also filled with the glass sealing material 4, the sticking strength increases.

IPC: H01L21/66
Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To obtain an evaluation method in which the end-face strength of a part recessed lower from a peripheral edge part such as a U-groove, a V- groove or the like and the end-face strength of a corner part to the outer circumference can be confirmed precisely and with good reproducibility, by a method wherein the end-face strength is evaluation on the basis of whether the generation of a very small chip exists or not or on the basis of the abrasion degree or the like of a groove straight-line part. SOLUTION: A wafer is placed on a stage for suction. The wafer is positioned by outer circumferential pins. The wafer is sucked and fixed. Then, in a state that the wafer is gripped by the outer circumferential pins and by a notch-part pin, the notch-part pin is pushed out to the peripheral edge of the wafer. After that, the notch-part pin is pushed into the V-groove of a notch again. This operation is repeated several times. After the operation is finished, the wafer is removed from the stage. Whether the generation of a very small chip exists or not in a notch corner part or whether the abrasion of a V-groove straight line part in the notch corner part or in the notch exists or not and the size or the like of the abrasion are confirmed by a microscope or the like. As a result, the end-face strength of the notch part is evaluated.

Filed: 1990-05-08
Abstract: PURPOSE:To keep a surface density constant by comparing the ratio of the surface density and a standard pattern image density with a reference value, and controlling an exposing quantity with the value of the compared ratio. CONSTITUTION:Toner density control forms the standard black pattern image on a photosensitive body 121, reads the reflection input of the irradiating light of a P sensor PSN, and compares the fact with the reference value of a toner density to turn on/off the toner replenishing roller clutch of a developing unit. When it is judged that the density is light, the clutch is turned on at every sheet till the 10th sheet of the next detecting time, and tone replenishing is continued via the replenishing roller. When it is judged that the density is dark, the replenishing is not carried out till the next detecting time. In toner density detection, the drum 121 is rotated, a light emitting diode 404 is turned on when a P sensor pattern image reaches a P sensor position, the P pattern image is irradiated with light, and reflected light is received by a phototransistor 403 to detect the density of the P pattern image. Thus, the surface density of the image can be kept constant.
