    摘要: A holding device of a frame retainer on a retainer holder used in bonding machines for manufacture of semiconductor devices including a pair retainer guides formed in the retainer holder so that the frame retainer is positionally secured between the retainer guides by positioning pins which are pushed and moved by spring members. The positioning pins are movable toward and away from the frame holder by turning (overcoming the spring force of the spring members) eccentric pins which are in contact with the positioning pins.

    摘要: A non-contact IC card communication in which power consumption of a driver of a reader/writer is reduced and the size of a power supply circuit for operating the driver is made small. The driver has a low output impedance. A current detecting circuit including a detecting coil magnetically coupled with a transceiver coil of the reader/writer through a magnetic coiling element and a resistor detects a current which flows through the transceiver coil. A voltage drop to be detected is small and is approximately constant for a variation of the transceiver coil current. When data is read from an IC card, a load of the driver is changed. The driver drives the transceiver coil in a constant voltage fashion even if a current flowing through the transceiver coil changes due to the change in load. Input voltages of a rectifying/smoothing circuit and a regulator in the IC card become approximately constant. As a result, the amplitude of a high frequency output voltage of the driver can be made small. Also, a high frequency signal current sent from a reader/writer is subjected to double modulation including amplitude modulation by card data and modulation by second information, such as information indicative of the abnormality of an IC card, in synchronism with a timing at which data transmission between the reader/writer and the card is made, and the second information is extracted by the reader/writer.

    摘要: A frame-type sprinkler head for dispensing fire extinguishing liquid. The sprinkler head includes a frame having a conducting hole therein through which fire extinguishing liquid may flow. The sprinkler head includes a valve body disposed adjacent to the conducting hole for blocking the conducting hole. The sprinkler head including a packing affixed to the valve body to prevent separation of the packing and the valve body. The packing is disposed between the conducting hole and the valve body for preventing leakage of the extinguishing liquid past the valve body. The sprinkler head includes a band-like protrusion extending from an edge of the packing. The band-like protrusion is engaged with an engagement portion provided on the frame for causing pivoting movement of said valve body and for preventing lodgement.

    摘要: A clamping device for bonding machines used in manufacturing semiconductors including a clamp receiver, a rotatable lock key movable in a vertical direction on the clamp receiver, an air cylinder which pulls up and down the lock key, and a clamp which has a bonding window for bonding tool and an opening for the lock key passing through it. The clamp is mounted on the clamp receiver by letting the lock key pass through the opening, and then the lock key is turned so as not to accord with the opening. When the air cylinder is actuated, the lock key is pulled down and presses the clamp against the clamp receiver, securely positioning the clamp on the clamp receiver. Thus, the changing operation of the clamp is easily and quickly performed because the clamp can be removed by merely rotating the lock key and turning on and off the air cylinder.

    摘要: A printing head for a wire dot printer includes a plurality of printing levers connected to a corresponding plurality of printing wires. A plurality of guide holes are operable for guiding the distal ends of the printing wires beyond a nose of the printing head. Each guide hole corresponds to one of the plurality of printing levers. As viewed from the nose of the printing head, each printing lever extends radially from its corresponding guide hole and the inner ends of the printing levers form a zig-zag pattern. A plurality of plate springs provides the resilient force to push the printing levers and thereby the printing wires toward the nose of the printing head. A spacer for supporting the plate springs equalizes the effective length of each plate spring.

    摘要: An error flag processor for digital signals includes a memory having an information word frame comprised of signal words and correction words, an error detector for detecting errors in an input signal in units of one frame, a write address circuit for writing into an error flag RAM one error flag for one frame upon detection of an error in the words of the frame, an error correcting circuit for correcting data subjected to de-interleave and a read out of the memory, and read address circuit for reading error flags in units of one frame corresponding to individual words from the memory to the error correcting circuit, whereby the storage requirements for the error flags can be reduced. When old storage regions for correction words in the information word frame memory are used as error flag regions and the error flags are arranged in accordance with the signal word frames, the error flag RAM can be omitted.

    摘要: Disclosed is a disc or tape signal reproducing apparatus having a first speed control loop in which the duration of a specific pulse in the PCM signal recorded on the disc or tape is detected and the current sync signal interval is anticipated from the duration of the pulse so that the motor speed is pulled into the operation range of the sync signal detector, and a second speed control loop which controls the motor speed basing on the sync signal reproduced by the sync signal detector. The motor speed is controlled by the first speed control loop until the sync signal detector detects the sync signal, thereafter the motor speed is controlled by the second speed control loop basing on the reproduced sync signal.
