IPC: G01G21/24
Filed: 1984-04-05
Abstract: PURPOSE:To obtain variation in the electrostatic capacity between a fixed and a movable electrode plate accurately by curving both electrode plates in the same breadthwise rectangle directions. CONSTITUTION:The fixed electrode 5' and movable electrode plate 6' are curved in the same breadthwise directions of rectangles. Then a body is placed on a rectangular upper counter pan 7 at a breadthwise end part and when an unloaded load (a) is placed, the upper counter pan 7 slants and a movable support plate to which the upper counter pan 7 is fitted also slants. Further, the movable electrode plate 6' fitted to the movable support plate also slants accordingly, but the movable electrode plate 6' moves within a range concentric with the fixed electrode plate 5' and only shifts in its position and its parallelism to the fixed electrode plate 5' is held constant. Therefore, even when the unloaded load (a) is applied, variation in the electrostatic capacity between both electrode plates 5' and 6' is obtained accurately.

Title: Method and apparatus for measuring partial circle
IPC: G01B21/20
Filed: 1992-03-26
Abstract: PURPOSE:To prevent an error of a partial circle from enlarging to appropriately perform shape inspection of the partial circle. CONSTITUTION:A partial circle center calculating means 36 measures positions of two points on a circumference of a concave partial circle 34A formed on an object 34 to be measured, wherein an intersection of an arc having a designed radius size with one of the two measured positions as the center and an arc having a designed radius size with the other position as the center, which is the intersection on a side of the partial circle 34A facing the circumference is assumed to the center of the partial circle. A radius vector evaluating means 38 obtains a radius vector from the assumed center to the circumference of the partial circle 34A to compare the obtained radius vector with the designed radius size to evaluate the partial circle. Thus the designed radius size of the partial circle 34A is used to assume the center of the partial circle 34A in advance, whereby a slight error caused on the measured value of the partial circle 34A can be prevented from enlarging when the center and a diameter of the partial circle 34A are obtained by calculation.

Title: Cvj boot made of resin
Inventor: IWATA TAKASHI
IPC: F16D3/84
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To prevent or suppress the twist of a large diameter attaching part when the large diameter attaching part of a boot is fastened by a band. SOLUTION: Many cut-out holes 19 which do not pass through a band stopper 17 are provided on the side surface of the band stopper 17 side of a band fixing groove 15 of a large diameter attaching part 13. Thus, when the band is fastened in the fixing groove 15, the cut-out holes 19 collapse due to the fastening force and a twist generated due to fastening is absorbed. When the band is fastened, the cut-out holes 19 are restricted circumferentially, so that the diameters of parts of the cut-out holes 19 of the band stopper 17 are reduced and they collapse toward the band side. Accordingly, an effect for preventing the fall out of the band is thus improved.

IPC: F02F1/00
Filed: 1996-03-26
Abstract: PURPOSE: To miniaturize a direct injection type diesel engine and improve the reliablity of cam bearing parts. CONSTITUTION: Cam bearing parts 10A-10G are arranged in bore center corresponding positions after shifting pressure contact parts 18 onto the cylinder bore center part side from the longitudinal view of an engine 1 in relation to cam contact parts 17 in an intake locker arm 19 and an exhaust locker arm 16, and head bolt holes are arranged only in the positions out of the cylinder bores from the longitudinal view of the engine 1 so that the cylinder bore centerline lies in between, thus facilitating the arrangement of the cam bearings 10A-10G into the bore center corresponding positions. A cam shaft 6 can thereby be disposed as close as possible to the cylinder bore center part from the cross direction view of the engine 1, so that the cross direction dimension of the engine 1 becomes as small as possible.  As a result, the engine 1 can be miniaturized in the cross direction, and the reliability of the cam bearing parts can be improved.

Title: Low noise gear
Inventor: HATTORI TOSHIHIKO
IPC: F16H55/14
Filed: 1987-03-24
Abstract: PURPOSE:To reduce the vibration and noise of a gear, by forming a soft nitriding layer, a porous oxide film layer with a lot of pores and an abrasion resisting resin layer laminatedly on a tooth surface, and constituting a part of abrasion resisting resin, composing the abrasion resisting resin layer, to have been charged in each pore of the oxide film layer. CONSTITUTION:Adhesion of an abrasion resisting resin layer 5 to a tooth surface 2 is improved by an anchor action owing to a fact that a part of abrasion resisting resin is made to be charged to a lot of pores 4a of an oxide film layer 4. Accordingly, even in case of adapting to a gear small in its module, separation of the abrasion resisting resin layer 5 due to slide motion of a tooth surface 2a is checked at time of operation of a power transmission system, and even if the resin layer 5 is worn out, a part of it is left behind in these pores 4a of the film layer 4. Consequently, such an effect as absorbing an engaging error in a gear 1 and a tooth noise due to backlash or the like is brought into full play, therefore the vibration and noise of the gear 1 in the power transmission system are efficiently abated.

Abstract: PURPOSE: To maintain the constant output irrespective of the altitude by detecting the compressor outlet pressure during the operation at the atmospheric pressure different from the specified pressure, comparing it with the stored pressure, and maintaining the outlet pressure according to the result by setting a bypass valve of a turbocharger to a required position. CONSTITUTION: While an engine 11 is operated, the absolute pressure from an outlet sensor 52 of a compressor 28 in a turbocharger 19 is read, and stored together with an engine speed input. Then, the read value is compared with the stored value of the outlet absolute pressure of the compressor 28 at the engine speed in the atmospheric condition of the normal sea level, and the opening of an outlet gate valve 22 which is a bypass valve to bypass a turbine 18 is changed according to the deviation. When the atmospheric pressure is higher than that on the sea level, the outlet gate valve 22 is kept closed. The outlet gate valve 22 is opened when the engine is operated at the altitude lower than the sea level (e.g. in a canyon).
