Title: Method for mounting electronic component
Inventor: OGATA YUJI
IPC: H05K13/08
Filed: 1997-09-24
Abstract: PROBLEM TO BE SOLVED: To provide a method for mounting an electronic component in which mounting precision of an electronic component is improved by accurately correcting displacement of the electronic part in θ-direction by using a pulse motor. SOLUTION: A magnetic body 17 is, in place of a nozzle attached to a nozzle shaft 16 of a transfer head 19. The magnetic body 17 is made to approach a magnet 28 of a rotation amount detecting unit 22 and rotated by a pulse motor 18. Then, the magnet 28 follows the magnetic body 17 for rotation due to magnetic force, with its rotational angle detected. A counter value of the detected rotational angle is compared to an angle command value outputted from a control part to the pulse motor 18, and an error in rotation amount of the pulse motor 18 is obtained as θ correction value. A nozzle is attached to the nozzle shaft 16 in place of the magnetic body 17, and an electronic part is mounted. The rotation of the pulse motor 18 is controlled, based on the θcorrection value, so that the displacement of the electronic part in θ direction is accurately corrected precisely.

Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To perform prescribed processing by reading data even in the case of write of defective data by providing plural memory blocks as buffer memory blocks for saving data when reloading data, designating, checking arid correcting these buffer memory blocks. SOLUTION: Buffer memory blocks are four memory blocks 451-454 and consist of a buffer area 45 and for each buffer memory block in this buffer area 45, the presence/absence of a write error is discriminated by performing an error check through a check code to the saved data memory block shown by the area number domain of the buffer memory block. When there is any error, the data in that buffer memory block are copied to a data block, the check code is prepared and written in a check code area and the number of times of write is updated, written in the data memory block and corrected. Thus, data can be prevented from being lost.

Title: Synchronizing signal separator circuit
Inventor: TAKAKUWA SEI
IPC: H04N5/06
Filed: 1986-10-31
Abstract: PURPOSE:To successively separate and take out a required horizontal synchronizing signal by directly connecting an inputted composite synchronizing signal to the output part of a PLL circuit through an analog switch when the first and the second analog switches are set to prescribed conditions respectively. CONSTITUTION:When the component of the horizontal synchronizing signal is deficient in an interval where a vertical synchronizing signal of the composite synchronizing signal is present, if the vertical synchronizing signal falls, the inverse of Q output signal of one shot multivibrator 1A goes to a low level to conduct the first analog switch 6, however, when a prescribed time elapses, it returns to a high level. The output signal of the Q terminal part of the one shot multivibrator 1A goes to a low level and the second analog switch 7 is conducted during the period of the vertical synchronizing signal and the composite synchronizing signal to a phase comparing circuit PD 81 is directly passed to an output part 3A through the switch 7. Thereby, the oscillation of a voltage control oscillator VCO83 is continued, so that during the existence of the vertical synchronizing signal, an output signal having a frequency coinciding with that of the horizontal synchronizing signal is obtained.

Title: Voice switch
Inventor: ISHIKAWA KATSUKI
IPC: G10L25/78
Filed: 1990-09-28
Abstract: PURPOSE:To prevent resonance and to avoid intermission of a voice caused at double talking without losing a natural sound sense by increasing or decreasing complementarily the gain of a part of a pass band of a voice signal and limiting the pass band of the incoming and outgoing voice signal. CONSTITUTION:For example, when an incoming voice signal detection circuit 3 detects an incoming voice signal, the circuit 3 outputs an incoming level signal to a CPU 7.
