Abstract: PURPOSE:To make a distinct improvement in the thermal efficiency and output capacity of an engine, by installing a hydraulic cylinder binding the compression ratio position of a piston pin, while interconnecting a through oil passage, leading to the hydraulic cylinder, to a feed oil passage in a cone rod. CONSTITUTION:A piston is made up of each symmetrical journal parts 7, 8 and a central crank part 9. Both first and second hydraulic cylinders Cy1 and Cy2 in order to tie a piston pin P down to a compression ratio position are installed. In this piston pin P, there are provided with through oil passages 221 and 222 interconnecting these hydraulic cylinders Cy1 and Cy2. These through oil passages 221 and 222 are interconnected to each of feed oil passage 231 and 232 installed in a connecting rod 14. Thus, a compression ratio is variably adjustable into two stages whereby the thermal efficiency and output capacity of an engine are sharply improvable.

Title: Component-supplying device
Inventor: SAITO KOJI
IPC: B23P19/00
Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To provide a component supplying device which is very suitable for supplying prismatic or flat prismatic components. SOLUTION: Around a fixed pipe 3, a magnet M1 for correcting the posture of a component which passes through the fixed pipe 3 is located in such a direction that the center line of magnetic force of it may cross the belt moving direction. Therefore, in the case that a component P to be supplied has a prismatic or flat prismatic shape, the posture (the direction in which the component rotates around a line connecting the centers of both end faces in the longitudinal direction of the component as an axis) of the component P can be corrected to such posture that it may match with an upper face of a belt 7 by means of magnetic force of the magnet M1 while it is passing through the fixed pipe 3. By this method, the supply of prismatic or flat prismatic components onto the belt 7 and the roll and carriage of the components by the belt 7 can be performed accurately.  By this device, the supply of prismatic or flat prismatic components can be done as perfectly as the supply of cylindrical components.

Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To provide a novel rotation converting device. SOLUTION: An impact screw fastening head, which is one application example of a rotation converting device, has a one-way clutch 1, an eccentric structure 2, and a torque transmission part 3. The eccentric structure 2 has an eccentric part 23 off-centered from the center C formed by both side shaft end parts 21, 22, its ring part 23a, a contact member 24 and the like. According to this, when one side shaft end part 21 is rotated from an input shaft 11c through the one-way clutch 1, the eccentric ring part 23 touches the contact member 24 to deform the eccentric part 23, which stores the distortion energy.  When the deformation is maximum, the distortion energy is released to impart a rotating energy to the eccentric structure, and the rotating energy is then transmitted from the contact part to the torque transmission part 3 to impart an impact torque to a nut to be fastened by its fastening part 32.

Abstract: PURPOSE:To acquire a smooth sound pressure frequency characteristic by using an axially asymmetric dust cap for which the apex of the dust cap is different from the center of the dust cap and a distance from the apex to the outer peripheral part of the dust cap is made different in various positions. CONSTITUTION:A dust cap 19 is coupled to an upper surface in the central part of a diaphragm 17 and the apex of this dust cap 19 is positioned different from the center of the dust cap 19. Then, the dust cap is made axially asymmetric so that the distance from the apex to the outer peripheral part of the dust cap can be made different in the various positions. In such the case, the intrinsic oscillation frequency of the axially asymmetric dust cap 19 is low in a direction, where the distance from the apex of the dust cap to the outer peripheral part of the dust cap is long, and the frequency is high in a direction where the distance is short. Thus, since the various intrinsic oscillation frequencies are acquired in various directions, keen peak is diffused and the smooth sound pressure frequency characteristic can be acquired.
