Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To increase rigidity of a slide pipe and improve performance and reliability by input reduction of a compressor at low cost by providing a reinforcing rib in a piston direction or in the direction perpendicular to a piston drum part in a slide pipe outer peripheral part which is directly connected with the piston. SOLUTION: In a sealed electric compressor in which the compressor part of a Scotch yoke type piston mechanism and an electric motor part are arranged on a frame upper part and a frame lower part, respectively, within a sealed container, a piston drum part 10b is reciprocated by a circular motion of a slider within a window opening part 10c of the slide pipe 10a of a piston 10 by revolution of a crankshaft due to the electric motor part and gas is compressed. In this case, a reinforcing rib 10d is provided on the outer peripheral part of the slide pipe 10a in the piston 10 and rigidity of the slide pipe 10a is increased. Thus, deformation and crack of the slide pipe 10a due to excessive pressure generated at the time of compressing gas are effectively prevented without inviting an increase in cost of a material and an increase of weight of the slide pipe 10a.

IPC: H01F29/04
Filed: 1989-04-24
Abstract: PURPOSE:To interrupt switching operation when any abnormality is predicted or when it is produced, by deciding whether or not the switching operation is correct by estimating switching time interval between taps on the basis of a signal from each operation time detection part and comparing the estimated time interval with preset time. CONSTITUTION:A title device includes a total switching time detection part 11 for detecting the operation time of a motor driven operating mechanism, a position detection part 134 for detecting the operation state of a tap selector, and a switching time detection part 12 for detecting the switching operation time of a switch.

Additionally, switching time estimated in a decision part 17 is received and compared with a set time, whereby it is decided whether or not the switching operation is correct. Thus, the switching time among said three parts are monitored for each switching operation. Hereby, the operation order of each device can be monitored, and the switching operation can be interrupted when it is produced, to prevent or the abnormality from being developed to any secondary trouble.

Title: Hammer drill
Inventor: SAKAMOTO YOSHIHIRO
IPC: B23B45/16
Filed: 1988-04-25
Abstract: PURPOSE:To eliminate a possible cause for rattling and an abnormal sound by providing a universal joint having an externally spherical form in a joint retainer in such a way as to be supported for free turn on the spherical internal surface of the retainer, and having the oscillation motion axis of a motion conversion member passed for free slide. CONSTITUTION:A piston 4 is made to reciprocate with a motion conversion member 5. A universal joint 54 having an externally spherical form with an axis 53 so inserted as to be freely slidable, is so made as to be capable of free 3-dimensional turn due to the internal surface of a joint retainer 55. As a result, a torsional force due to the turning force of the axis 53 does not work upon a slide surface. Furthermore, a slide contact surface between the universal joint 54 and the joint retainer 55 is so large that a load per unit area is small. Thus, the contact surface is subject to an extremely small abrasion. In addition, even if an abrasion occurs on the contact surface, rattling does not occur because the universal joint 54 is pressed to the spherical internal surface of the joint retainer 55 with the energizing force of a joint spring 56.

Filed: 1983-06-08
Abstract: PURPOSE:To enhance the life of a vacuum pump by providing possibility of releasing engagement of the rod part of an operational piston with the swinging end part of a locker arm. CONSTITUTION:When the neg. pressure in a vacuum tank has attained No.1 specific pressure value A, a diaphragm piston 68 slides to the left. Accordingly No.1 check valve 60a is put back in function, and the No.2 check valve 60b out of function. When an operational piston 20 is moving downward, a piston 61 slides down together with said operational piston 20, but the upward sliding is restricted. Consequently the engagement of the seat part 22b of an operating rod 22 with the bottom fork 32 of a locker arm 30 is released to cause stop of the vertical motion of the operational piston 20, and now the locker arm 30 swings in approx. no load state. Thereby the vacuum pump can be kept out of operation, if it is not required.
