Title: Polishing device for magnetic sheet
Inventor: NAGASHIMA YASUO
IPC: G11B5/74
Filed: 1986-10-24
Abstract: PURPOSE:To prevent the re-adhesion of magnetic powder by making the side face f the downstream side of a scraper roughly vertical against the slide-contact surface for slide-contacting a magnetic sheet. CONSTITUTION:A magnetic sheet 1 rotates in the direction as indicated with an arrow a, and also, a sapphire chip 10 which becomes a scraper is attached to a base plate 3. The sapphire chip 10 is shaped like a prism in which a slide- contact surface 10a is about 0.3mm angle. Accordingly, an angle theta1 made by a side face 10b of the upstream side and a magnetic surface 1a, and an angle theta2 made by a side face 10c of the downstream side and the magnetic surface 1a become both 90 deg.. Also, a slanting groove 11 is formed on the side face 10c. In such a way, even if a magnetic lump of the magnetic surface 1a is scraped by the sapphire chip 10, the scraped magnetic powder drops downward naturally, and it does not occur that said powder is accumulated on the side face 10c.

Title: Terminal electrode for spark plug
Inventor: KAGAWA JUNICHI
IPC: H01T13/39
Filed: 1990-09-25
Abstract: PURPOSE:To prevent flashover from occurring by using a steel material added with Mn instead of Cr for terminal electrode thereby improving the strength of nickel-plated surface and the hardness of the terminal electrode. CONSTITUTION:The terminal electrode 4 heat sealed with glass seal 11 together with a resistance member 5 in an axial hole 6 in an insulator 2 is made of a steel material added with 0.28-0.5% of C, 0.15-0.35% of Si, and 1.15-1.70% of Mn. During the cooling process of the glass seal, the electrode 4 is prevented from softening, and adhesion property relative to a nickel-plated layer for anti- oxidation is improved by the generation of acicular crystals due to martensitic or bainititic transformation. This provides the electrode 4 of a sufficiently high Vickers hardness and prevents separation of the nickel plated layer, and wear and flashover of the electrode 4 and a plug cap are prevented.

Title: Flat tube evaporator
Inventor: FUKUSHIMA TOSHIHIKO
IPC: F28F9/02
Filed: 1985-11-13
Abstract: PURPOSE:To reduce the proportions of an overheated gas region as against a liquid return region at an outlet part of an evaporator and thereby enhance cooling capability, by dividing an inlet-side header pipe into the longitudinal direction into a plurality of pieces, and disposing the coolant inlet ports of the divided header pipes in the same direction.

Title: Signal delay circuit
Inventor: MORIYAMA HIDEKI
IPC: H04N5/372
Filed: 1992-09-22
Abstract: PURPOSE:To simplify and miniaturize the constitution of a signal delay circuit and to omit all control jobs of the circuit by controlling the delay time of a filter means based on the undelayed input signal and the signal accordant with the delayed output signal. CONSTITUTION:The video signal is inputted to an OCD delay line 11 and delayed by a prescribed time. Then the delayed video signal is delayed again by an LPF 12 and outputted with elimination of the noise component. Meanwhile a control circuit 13 detects the positions of the horizontal synchronizing signals of the undelayed and delayed video signals through the 1st and 2nd synchronizing signal detecting circuits 14 and 15 respectively. If the phase delay time of the detection signal of the circuit 15 is smaller than a single horizontal period against the detection signal of the circuit 14, the output signal of a phase comparator 16 is kept a H only in a period accordant with the phase difference. If the delay time of the delay video signal is larger than a single horizontal period, the output signal of the comparator 16 is kept at L only in a period accordant with the phase difference. A control signal generating circuit 17 sends the DC voltage accordant with the output signal of the comparator 16 to the LPF 12 and controls the delay time to the value equivalent to a single horizontal period.
