Filed: 1993-03-29
Abstract: PURPOSE:To always, correctly record data by omitting the influence of such intrinsic deffects of disks as scratch, dust, etc., and selecting optimum recording powers for various kinds of disks correctly. CONSTITUTION:At first, a first error number measuring means 71 performs certifyings on each sector in the test writing area of a disk 1 via a recording and reproducing controlling means 75 and measures numbers of intrinsic errors in respective sectors corresponding to constant recording powers and the results are stored in a memory 8. Next, a second error number measuring means 72 performs certifying on the same place on the disk 1 via the recording and reproducing controlling means 75, measures numbers of real errors corresponding to respective recording powers changed within a prescribed range and the results are sent to a real error number calculating means 73. Then, the real error number calculating means 73 calculates numbers of true errors from the difference between the numbers of real errors and the numbers of the intrinsic errors stored in the memory 8 and an optimum recording power selecting means 74 selects a recording power making the numbers of true errors minimum as an optimum recording power.

IPC: H01P3/08
Filed: 1984-04-09
Abstract: PURPOSE:To prevent a center conductor and a metallic housing from being contacted by using a cylindrical outer conductor with bottom having a center conductor at the center of a bottom plate and a ring slot at an outer circumferential face. CONSTITUTION:The center conductor through-hole 21 having a prescribed inner diameter is provided to the center of the cylindrical outer conductor 19 with bottom and the ring slot 20 to which a solder ring 24 is inserted is formed on the outer circumferential face. The center conductor 18 is sealed with glass to the through-hole 21 so as to be penetrated to the axial center of the outer conductor 19 and subjected to hermetic sealing. While a solder ring 24 is inserted into the slot 20 of the connecting terminal 17 formed in this way, after the ring 24 is inserted into a connecting terminal inserting hole 23 provided to the metallic housing 2, the ring is heated and molten. Since the solder ring 24 is molten in the slot 20, it does not flow and contact the center conductor 18. Thus, the contact between the center conductor and the metallic housing are prevented.

Title: Gear control device of vehicle
Inventor: KURODA MASAHIKO
IPC: F16H59/68
Filed: 1989-03-23
Abstract: PURPOSE:To carry out manual gear change even when the electric system is out of order by providing a shift linkage between an operating lever and a gear shift shaft, and providing the linkage with an actuator, and providing the operating lever with a shift switch, and connecting a controller to the actuator. CONSTITUTION:When actuation of the electric system is disabled due to breaking of a wire, etc., an actuator 18 is set free. Under this condition, when an operating lever 7 is shifted to e.g. the F side, a case main body 14 shifts to the F side, whereby the hook 29 of a first shift wire 15 (shift linkage) shifting to the R side relative to the main body 41 compresses a spring 32 by means of a plate 34 and its shift is regulated by a stopper 35. Operating force acting on the casing main body 14 therefore acts on a wire 25 and so a desired gear is engaged by a second shift wire (shift linkage) 22 which is stretched via the turning movement of a lever (shift linkage) 17 in the F direction. Gear change can thus be performed manually.

Abstract: PURPOSE:To contrive to recover heat over a wide range (to recover heat down to cryogenic range) by a structure wherein a non-leak steel type air preheater is installed against the high temperature portion, in which corrosion occur comparatively slightly, and a non-leak ceramic type air preheater is installed against the low temperature portion where corrosion occurs heavily, of exhaust gas. CONSTITUTION:A non-leak steel plate type heat exchanger is employed as a preheater 3 of high temperature air, in which corrosion is comparatively out of question, and a non-leak ceramic type heat exchanger is employed as a preheater 6 of low temperature air, which has a temperature lower than the acid dew point of exhaust gas and consequently is of extremely corrosive atmosphere. Said two kinds of heat exchangers are combined so as to be installed in the order of the high temperature air preheater 3, a dry type electric dust collector 4, an induced draft fan 5, and the low temperature air preheater 6. Thus, the heat recovery down to a lower temperature range lower than before by about 30 deg.C can be possible without being restricted by low temperature corrosion (sulfuric corrosion), from the aspect of which the heat recovery at the low temperature range of exhaust gas (the lowest tempeature limit of heat recovery is usually about 130-140 deg.C of exhaust gas) is conventionally made impossible.
