Title: Pll synthesizer
Inventor: SATO KATSUYUKI
IPC: H03L7/18
Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To expand with a simple circuit constitution the pulling range and oscillation range of an oscillation frequency and to make the oscillation frequency high in precision. SOLUTION: The output signal of a phase comparator 14 is filtered and smoothed by a filter 16. With the filter output signal, a 2nd voltage-controlled oscillator 13 is controlled, and the output signal of the 2nd voltage-controlled oscillator 13 is inputted to the phase comparator 14. With the filter output signal, a DC voltage source 15 is controlled to obtain a variable DC signal. An adder 17 superposes the variable DC signal and filter output signal one over the other, to control a 1st voltage-controlled oscillator 11. The output signal and the input signal of the 1st voltage-controlled oscillator 11 are added and inputted to the phase comparator 14.  Thus, the variable DC signal is superposed on the input of the 1st voltage-controlled oscillator 11 to expand the oscillation range of the oscillation frequency, then the pulling range and oscillation range of the oscillation frequency can be expanded with the simple circuit constitution using neither a signal generator nor a 2nd filter.

Title: Failure diagnostic apparatus for fuel vapor processing device
Inventor: TAGA TAKANORI
IPC: G01M15/00
Filed: 1998-11-24
Abstract: PROBLEM TO BE SOLVED: To increase the chances of performing diagnoses on the failure of a canister by making effective use of diagnostic results during the travel of the vehicle. SOLUTION: Fuel vapor captured in a canister 12 is purged to an intake passage 7 and has its flow rate regulated by a purge control valve 20. During the travel of an automobile, an electronic control unit(ECU) 41 executes a first diagnosis related to the airtightness of the canister 12 on the basis of the behavior of canister internal pressure after intake negative pressure is temporarily introduced. If the result of the first diagnosis indicates failure, the ECU 41 executes a second diagnosis, during idle operation after the completion of the first diagnosis, on the basis of the canister internal pressure after the intake negative pressure is temporarily introduced; if the results of both diagnoses indicate failure, the presence of the failure in the canister 12 is finally determined. During execution of the second diagnosis, the ECU 41 detects by means of a vehicle speed sensor 37 the degree of a working force which opens atmospheric control valves 14, 15 inadvertently during the travel of the automobile, and permits the second diagnosis when the degree of the working force is smaller than a criterion.

Title: Low bias heterodyne optical fiber communication link
Inventor: ROORENSU JIEI REMUBO
IPC: H04B10/152
Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To provide an optical communication link having generic linear transfer and a high dynamic range which are suitable for transmission of an analog signal. SOLUTION: An optical luminance modulator 32 which is biased to a low bias point to reduce the noise and an optical heterodyne detector 34 which restores a transmitted modulation signal are included. A heterodyne generates a side band including the same information as a beat frequency signal and the modulation signal without a second higher harmonic distortion component. Using the low bias point reduces the noise and increases the dynamic range but is not performed without sacrificing the second higher harmonics distortion because the modulator output is a function of the square if the modulation signal. Though the second higher harmonics can be filtered, the band width of the modulation signal is limited to a value smaller than an octave. The heterodyne generates the side band which is changed by the root of the modulation transmission characteristic.  Consequently, generic transfer is practically linear, and the second higher harmonic distortion is erased, and the modulation signal can be extended over the multi-octave band width.

IPC: H03K19/0948
Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To reduce the current consumption by making an output transistor(TR) conductive when a gate voltage control circuit stops a gate control operation and reaching an OFF state without current flowing in itself. SOLUTION: Output signals from an output transistor(TR) drive circuit 6 receiving signals, the inverse of OB and the inverse of OE are determined and the output signals are given respectively to a gate voltage control circuit 13 and a TR 2. When either of CS and INI signals is at a low level, a gate voltage control circuit 13 is switched off and then a function of controlling a drain voltage of a TR 5, that is, a gate level of an output TR 1 in response to a power supply voltage is lost, instead an N-channel TR 12 is conductive to fix a gate level of the TR 1 to a GND level. Current flowing to a power supply voltage detection and power supply circuit 10 is prevented when it is not required to control a gate level of the TR 1 such a state as power-down as above.

Filed: 1992-11-18
Abstract: PURPOSE:To prevent excess movement and to protect a diaphragm from an external shock by restricting the moving permissible range with a magnetic piece mounted on the diaphragm in the inside of a resonance chamber provided to one surface side of the diaphragm. CONSTITUTION:A movement limit cover 28 limiting the movement in the central part of a diaphragm 18 is placed in the inside of a resonance chamber 22 forming a resonance space formed in the inside of an outer case 2. The movement control cover 28 is made of a metal or a synthetic resin or the like and its edge is inserted between a step 29 formed in the inside of the outer case 2 and a magnet 16 and fixed. A projection 30 forming a truncated trapezoidal shape is formed by bending the dge side upward to the moving limit cover 28 and a distance D between the projection 30 and a magnetic piece 20 is set equal to or slightly larger than the usual vibration allowable range. Thus, even when a shock is exerted to the diaphragm, generation of exfoliation force between the diaphragm 18 and the magnetic piece 20 is surely prevented and an inconvenience such as deformation of the diaphragm 18 is surely suppressed.
