Title: Device and method for detecting operation and maintenance cell
Inventor: SUGAYA TOSHIHIKO
IPC: H04L12/70
Filed: 1999-07-05
Abstract: PROBLEM TO BE SOLVED: To obtain a device and a method for detecting an operation and maintenance cell(OAM cell) not to adversely affect to a normal line, when a fault is generated and by which one fault position is grasped even when a double fault is generated. SOLUTION: A discard signal is generated when a timer counter value to count a prescribed time, within one second after the OAM cell is received is smaller than a reference value by a timer counter comparator 4. When a switching instruction flag of display of the fault position is zero, fault position display information of the newly received OAM cell is compared with the previously stored fault position display information, and when the pieces of information to not agree, the discard signal is generated.  When the switching instruction flag of display of the fault position is 1, the fault position display information of the newly received OAM cell is compared with the previously stored fault position display information even when the pieces of information do not agree, no discard signal is generated, the previously stored fault position display information is updated to the fault position display information of the newly received OAM cell and the switching instruction flag of display of the fault position is set as zero by a fault position display comparator 6.

Title: Multiplex information recording system
Inventor: KURODA KAZUO
IPC: H04S3/00
Filed: 1982-10-30
Abstract: PURPOSE:To record the interchangeable 4-channel sound information, by modulating a subcarrier with a subchannel signal and using a signal obtd. by processing the main carrier by the FM processing with a signal superposed on a main channel signal. CONSTITUTION:For FM modulators 11 and 12, the frequency shift is set at + or -100kHz for modulation of a main channel signal. While the frequency shift is set at + or -45kHz in a monaural mode and at + or -60kHz in a stereo mode respectively for modulation of a subchannel. This subchannel signal is obtained by applying FM modulation to the subcarrier by modulators 9 and 10, and the frequency of this subcarrier is set triple as high as a horizontal synchronizing frequency. At the same time, the main carrier is set at 1/4 offset to the horizontal synchronizing frequency. This minimizes generation of beats to a reproduced screen due to an audio carrier.

Title: Pulse motor driver
Inventor: YOSHIMURA GENICHI
IPC: H02P8/32
Filed: 1981-11-28
Abstract: PURPOSE:To prevent a rotor from unnecessary vibration, by detecting rotor movement in the neighborhood of objective position by position and speed detectors for the rotor, and giving a final exciting signal which varies step by step at a previously-selected rate. CONSTITUTION:A start signal SP and a signal of motor PM position detector PDC are put into an OR1 circuit. Values of a counter CON and a set signal OPS are compared and a gate G is controlled. The motor PM is controlled by their output via an OR2 circuit, a divider DIV, and a waveform generator SVC. A signal of minimum speed detector VDC controls the waveform generator SVC and the OR2 circuit via a flip-flop FF. Therefore, an exciting signal which varies step by step at every detection of zero speed after reaching a stable point, one step before the objective position is given. This prevents unnecessary vibration  and enables correct stopping.

Title: Bulk chip alignment feeder
Inventor: OKUHARA CHIYOSHI
IPC: H05K13/02
Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To provide a bulk chip alignment feeder which is lessened in external dimensions, reduced in initial cost, and capable of being kept free from trouble that a guide groove is bocked, by a method wherein a case is made to pivot in a vertical position, bulk chips are introduced into a guide groove taking advantage of their own weight and aligned, then the case is returned to a horizontal position, and the bulk chips are taken out of the case. SOLUTION: Bulk chips 42 are stocked in an empty space 43, and a bulk cassette 23 is held in a vertical position. The bulk chips 42 inside a hopper 44 are introduced into a guide groove 47 and get sliding down in the groove 47. When the bulk cassette 23 is kept in a vertical position, a front wall 46 of the hopper 44 forms a funnel path fronting the recess of the upper stringer of a case, so that the bulk chips 42 are smoothly guided into the guide groove 47. When the bulk cassette 23 is switched in attitude from a vertical position to a horizontal position, bulk chips stacked up in a heap in the funnel path collapse and fall into the hopper. There-fore, even if it occurs that a guide groove is blocked with bulk chips, the guide groove is capable of recovering from blockage.

IPC: H04N7/15
Filed: 1990-07-20
Abstract: PURPOSE:To display normal contents again at a terminal generating abnormality by transferring data required for conference display to the relevant terminal again to recover a display screen to a normal state. CONSTITUTION:When abnormality is generated at one of terminals 12, 13, to 14 and the display screen of each display part 34 is obviously different, a communication conference controller 10 interrupts a communication sequence for conference and a terminal state storage control part 20 transmits the data in a normal state simultaneously, successively to the specified terminal or to all the terminals 12, 13, to 14. By using this data, a control part 30 of the terminal receiving the data in the normal state recovers the display screen of the display part 34 to the normal state. Thus, even when abnormality is generated at one of terminals 12-14, the terminals 12-14 can display the normal contents again.
