Inventor: ONO KOICHI
IPC: H04B17/17
Filed: 1994-05-17
Abstract: PURPOSE:To provide a carrier frequency monitoring circuit for digital radio transmitter with which the carrier frequency of a modulated signal can be measured and monitored with no interruption. CONSTITUTION:The frequency of a digital modulated signal S2, for which an intermediate frequency signal S1 is digitally modulated by a modulating means 2 corresponding to a clock signal S0, is converted by a converter means 4 while using a high frequency carrier signal S3, and this modulated signal S5 is branched by a branching means 6. Then, this signal S5 passes through a band filter 7 with a band width to pass a signal at an adjacent frequency with a first frequency, which is separated from a central frequency fc of the signal S5 just in a frequency increasing direction just for the frequency of the signal S0, as a center while keeping the central frequency similar to this first frequency and a level L1 of this passed signal S5 is detected by a detecting means 8. Afterwards, the level of the signal corresponding to the first frequency within the level L1 is monitored by a monitoring means 9 and when this level is deviated from a prescribed level, it is detected that the carrier frequency of the signal S5 is deviated.

Title: Fault restoration system for computer
Inventor: HASEGAWA HIROSHI
IPC: G06F11/00
Filed: 1990-04-19
Abstract: PURPOSE:To automatically, quickly and accurately restore a hardware fault by combining the output of a diagnostic program with an unmanned robot which switches a fault suspected package to a stand-by package. CONSTITUTION:A fully automatic fault restoring robot 3 starts a manual diagnostic program of a computer system 1 via an interface device 2 for robot 3. The computer system 1 transmits the running result of the manual diagnostic program to the robot 3 via the device 2. Thus the robot 3 stops its operation when deciding that the fault of the system 1 is restored. If the robot 3 decides that the fault of the system 1 is not restored yet, the robot 3 takes successively the stand-by packages out of a stand-by package store shelf 4 in response to other fault suspected packages and repeats the same operations. As a result, a hardware fault is automatically, quickly and accurately restored.

Title: Mounting method for electronic component
Inventor: AKATSUCHI KAZUYUKI
IPC: H05K13/04
Filed: 1993-04-30
Abstract: PURPOSE:To enhance the productivity of a chip mounting operation on a board without lowering the operating efficiency of an apparatus so much by a method wherein, when a suction detector detects that a transfer head has failed to pick up a chip, a subsequent transfer head performs a recovery operation and mounts the chip on the head. CONSTITUTION:When a suction detector 11 detects that a transfer head B has failed to pick up a chip 9a, a component feeder 10 feeds a next chip 9a to a picking-up position in the U-direction, and a subsequent transfer head C picks up the chip 9a and mounts it on a board. When any transfer head fails to pick up a chip, a subsequent transfer head picks up the chip and performs a recovery operation. During this time, the component feeder 10 for which a picking-up mistake has been made is not moved to the transverse direction and is kept stopped. Consequently, since the time to move the component feeder 10 to the transverse direction is not required, the operating efficiency of an apparatus is not lowered.
