Title: Semiconductor device
Inventor: ISHINO KOJI
IPC: H03K19/173
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To prevent the relative shift of phases from being caused in amplified signals in a semiconductor device which is provided with amplifiers that respectively amplify an externally received clock signal and an input signal. SOLUTION: A 1st amplifier 1 supplied with operating power supplies V1, V2 produces a clock signal CLK which is an amplified external clock signal EXCLK. A 2nd amplifier 2 supplied with internal power supplies V3, V4 resulting from stepping up or down of an external power supply produces an input signal 'in' being an amplified external input signal Exin. An internal circuit 3 receives the input signal 'in' generated by the 2nd amplifier 2, based on the clock signal CLK generated by the 1st amplifier 1. A synchronization means 4 changes the operating power supplies V1, V2 supplied to the 1st amplifier 1 synchronously with the internal power supplies V3, V4 supplied to the 2nd amplifier 2.

Title: Remote monitor control system
Inventor: YAMAGUCHI YASUSHI
IPC: H02J13/00
Filed: 1982-08-14
Abstract: PURPOSE:To prevent a duplicated address by detecting the assignment of the address at the level judge section of a main operating panel, when the same address is assigned to >=2 terminal devices in error by the main operation panel. CONSTITUTION:In transmitting information to a terminal device from the main operation panel 1, a start pulse, a terminal address and a control data are converted into a format at a transmission signal forming section 18 and the result is transmitted from a signal line driver circuit 17 to a line 2. If the main operation panel 1 transmits the information with the same address to K-set of terminal devices in error, R1-Rk are connected equivalently in parallel to a signal line 2 at the transmission of a return signal. Since the resistance values of the resistance R1-Rk are almost equal, the return current is almost K times as large as the current with no address duplication. Thus, when the level is compared with a prescribed reference level at signal level judge sections 221-22n, the number of terminal devices of the same address connected to the signal 2 is judged.

IPC: H03M13/23
Filed: 1987-06-08
Abstract: PURPOSE:To attain quick transition to the steady-state mode without plural number of repetition of useless branch retrieval by providing a monitor mode between the state of storing the information bit and the steady-state mode applying normal decoding to all stages of shift registers of a re-decoding section. CONSTITUTION:The re-decoding section 3 receives a reset signal from a start control section 8 and stores the information bit reproduced from a reception signal series into a shift register. The re-coding series obtained from the branch reproduced from the reception series is given to a metric arithmetic section 5, where the series is compared with the received series and a path metric value GAMMA<(t)> is calculated. A threshold value comparison section 7 compares the value with a threshold value GAMMA0 inputted from the start control section 8 in advance. If the path metic value GAMMA<(t)> exceeds a high-order threshold value GAMMAsu, the mode is transited from the search mode into the monitor mode. The start control section 8 sends a brunch selection inhibition release pulse to a branch selection section 2 and sends a return signal to an algorithm control section 6 to be transited to the normal decoding process.

Title: Stabilizing circuit for comparator output upon power on
Inventor: AMADA TAKUMA
IPC: H02J1/00
Filed: 1990-06-01
Abstract: PURPOSE:To operate a third comparator stably by applying a voltage earlier on the non-inverted input terminal '+' than on the inverted input terminal '-'thereof. CONSTITUTION:Upon turn OFF of a power switch, a first low potential at the non-inverted input terminal '+' of a second comparator 33 drops below the potential at the non-inverted input terminal '-' on which a voltage has been applied from a terminal e through a delay circuit, thus turning the second comparator 33 ON. Consequently, a capacitor 38 is discharged through the second comparator 33 immediately upon turn OFF of the power switch. Since a voltage is applied earlier on the noninverted input terminal '+' of the third comparator 33 than on the inverted input terminal '-' thereof upon turn ON of the power switch, initial state of the third comparator 33 can be turned OFF.

Filed: 1988-06-08
Abstract: PURPOSE:To utilize a deceleration function at maximum by providing a deceleration characteristic curve measuring means, and setting a tape speed zero point on a measured deceleration characteristic curve so as to coincide with a targeted position. CONSTITUTION:A deceleration start position setting means 11 decides a deceleration start position based on the targeted position and speed, and stops a tape before it arrives at the targeted position. When the position of the tape 1 passes the deceleration start position, a tape running control part 15 starts a first deceleration operation. Then, the deceleration characteristic curve measuring means 13 starts the measurement of the deceleration characteristic curve, and re-sets the deceleration characteristic curve by a deceleration characteristic curve re-setting means 14 so that a position where tape speed goes to zero can coincide with the targeted position. And the control part 15 interrupts the first deceleration operation, and executes a second deceleration operation at a time when the tape 1 is fed at re-set tape speed. By performing the above speed control, it is possible to utilize deceleration capacity at maximum, and to shorten a search time.
