Inventor: SUZUKI ATSUNOBU
IPC: G01N33/20
Filed: 1977-12-29
Abstract: PURPOSE:To enable the graphite spheroidization ability of molten metal of spheroidal graphite cast ion rapidly and surely in fundry by rupturing the sample of the specific dimensions having been cast in molds, grindling only the minute portion of the fracture surface and observing the ground surface with a metal reflecting microscope. CONSTITUTION:The molten metal immediate after spheroidization treatment is cast in a mold 21 which has a cavity 22 of 15 to 25 mm in diameter and about 100 mm in depth. The test blank having been drawn out after the molten metal has solidified is hammered at its approximate central part and is thereby ruptured. One of these is held and fixed in a sample fixing device 2 which is mounted on the working table 9 of a stanchion 10. Next, an abrasive material 3 is fixed to a chuck 4 and rotating power is applied to a revolving shaft 5 by way of a motor 8 and reducer 9. Thereafter, the abrasive material 3 is lowered by turning a revolving shaft elevating handle 6 and is pressed to the sample 1, by which the minute portion of the sample 1 is concentrically ground. The sample 1 is then removed from the chuck 4 and its ground surface is observed with a metal reflecting microscope.

Title: Nickel electrode for alkaline storage battery
Inventor: KODAMA MITSUHIRO
IPC: H01M4/32
Filed: 1999-06-07
Abstract: PROBLEM TO BE SOLVED: To enhance an active material utilization factor and improve a high- rate discharge characteristic by applying etching to a metal porous substrate and by applying cobalt-plating to it. SOLUTION: This nickel electrode is made by filling an active material containing nickel hydroxide as a main constituent in a metal porous substrate. When etching and cobalt-plating are applied to the substrate, the surface of the substrate is roughened and unevenness is imparted to it. Thereby, the coming-off of the active material from the substrate is prevented, and the contact area of the active material to the substrate can be increased. The plated cobalt is electrochemically oxidized during initial charging, a conductive layer of high-order cobalt oxyhydroxide is formed in the vicinity of the substrate, and the active material is connected to the substrate, so that a battery having a high active material utilization factor and an excellent high-rate discharge characteristic can be provided. A cobalt-plating amount of the substrate is preferably set to 0.3-10 mg/cm2.

Title: Track jump control circuit
Inventor: NAKANE HIROSHI
IPC: G11B21/08
Filed: 1983-08-31
Abstract: PURPOSE:To eliminate deterioration in control precision due to the delay of the first transition of a feed motor device by detecting the timing of inversion from the opposite direction when jumping operation is started, and starting the operation of a counter with the detection output. CONSTITUTION:A high-frequency information signal RFS and a tracking error information signal TES are supplied to a direction component detecting circuit 15 to detect a jump direction component, and a direction inversion detecting circuit 16 detects the inversion of the jump direction with the detection signal to clear a counter 11. Therefore, the jumping operation is carried out in the opposite direction of a specific direction until the feed motor starts, so the inversion of the direction in said period is detected to start the counter 11, and consequently the counter 11 starts simultaneously with the startup of the motor device, thereby eliminating an error in the number of jumps due to the eccentricity of a disk originating from the startup delay of the motor device.
