  • Patent number: 11784017
    Abstract: An electromagnetic relay includes a pair of fixed terminals including a fixed contact, a movable contact piece, a housing portion, and a magnet portion. The movable contact piece includes a movable contact disposed facing the fixed contact. The movable contact piece is movable in a first direction in which the movable contact contacts the fixed contact and a second direction in which the movable contact separates from the fixed contact. The housing portion includes a housing space housing the fixed contact and movable contact piece. The magnet portion includes a pair of magnets disposed around the housing portion so as to face each other in a longitudinal direction of the movable contact piece and extending in the second direction beyond the housing space. The magnet portion generates a magnetic flux flowing in a direction parallel to the longitudinal direction between the fixed contact and the movable contact.

  • Patent number: 11756759
    Abstract: An electromagnetic relay includes a fixed contact, a movable contact piece having a movable contact, a drive shaft, an electromagnetic drive device, and a positioning portion. The movable contact piece is movable in a first direction contacting the fixed contact and in a second direction separating from the fixed contact. The electromagnetic drive device includes a movable iron core integrally movably connected to the drive shaft. The electromagnetic drive device switches between a contact state in which the movable contact comes into contact with the fixed contact and a separate state in which the movable contact is separated from the fixed contact by moving the drive shaft with the movable iron core. The positioning portion positions the drive shaft or the movable iron core in the separate state. The drive shaft or the movable iron core includes a first inclined portion that contacts the positioning portion in the separate state.

  • Publication number: 20140175065
    Abstract: In spot welding, the condition tolerance for applying a large current in a short time into an aluminum alloy plate or the like is narrow, and also nugget crack sometimes occurs in spot welding. In the case of a mild steel plate, the expulsion sometimes occurs, and thereby a poor weld portion is formed. Due to a pickup removal operation from an electrode tip, the operating ratio is reduced. Here, a PAM control method is employed for raising or dropping a rectified and smoothed voltage EDC output to an inverter circuit, according to a certain set-up ratio in a predetermined time, instead of a conventional PWM control method. By this control method, the nugget can be formed in condition of low heat dissipation and high thermal efficiency. In addition, energy saving and power saving are achieved by using the PAM control method.

  • Publication number: 20050066112
    Abstract: A data read/write control system includes memory divided into a plurality of blocks, a write unit, and a read unit. When writing data to one block of the plurality of blocks, the write unit compares a size of the data with a capacity of a blank area of the block. If the size of the data is larger, the write unit erases all data stored in the block and sequentially writes the data to the block from top or end. If, on the other hand, the size of the data is smaller, the write unit sequentially writes the data to the block from an area next to an area where data is stored. When reading data from the block, the read unit sequentially searches the block from top or end to find an area where data is written last, and reads the data stored in the area.

  • Publication number: 20050008499
    Abstract: A displacement control mechanism used in a variable displacement compressor for controlling a displacement of the compressor includes a first control valve located on a supply passage and a second control valve located on a first bleed passage. The second control valve includes a backpressure chamber having substantially the same pressure atmosphere as a region of the supply passage downstream of the first control valve and a spool including a back surface that is located in the backpressure chamber. The spool reduces an opening degree of the first bleed passage when a pressure in the backpressure chamber is increased. The spool blocks a communication between the backpressure chamber and the first bleed passage via a clearance formed around a cylindrical outer peripheral surface of the spool in the second control valve when the spool sets the first bleed passage at a minimum opening degree.

  • Patent number: 5377972
    Abstract: A sorter for sorting sheets out is provided with a bin unit including a plurality of bins having specified length and width and a bin shifting mechanism for shifting the bin unit upward and downward. The respect ire bins are vertically spaced apart and adapted for placing the sorted sheets thereon. The sorter is further provided with a first detector for detecting that the bin unit has been moved down to a home position region defined in a lower portion of the sorter, and a shift controller for controlling the bin shifting mechanism. The shift controller shifts the bin unit downward until the first detector conducts the detection when the bin unit is not in the home position region when the power is applied the sorter. Accordingly, the home position of the bin unit can be detected accurately with a simple structure.
