Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To reduce dispersion in a convergence frequency of a system clock due to difference from a frequency of a reference signal and to avoid a lock range of a phase locked loop(PLL) from being deviated. SOLUTION: A PLL comprises a phase comparator 1, a low pass filter section 2, a voltage controlled oscillator (VCO) 5, and a frequency divider 6.

Title: Laser device provided with optical modulator
Inventor: SASAKI NOBUO
IPC: H01S5/042
Filed: 1988-03-31
Abstract: PURPOSE:To enable a superhigh speed optical modulation by a method wherein an electrical field is applied onto a multi-quantum well (MQW) optical waveguide layer of an optical modulator, which is monolithically formed on a semi-insulating substrate, to make it change in a refractive index and an LR time constant of the optical modulator is made small. CONSTITUTION:In a laser device provided with an optical modulator, when a current is injected into a p electrode 9 of a laser section B from a terminal 8, a laser oscillation starts and the emitted laser rays are guided to an MQW optical waveguide layer 6 of an optical modulator section A through a semi-insulating buried layer 18. When a control voltage applied on a terminal 1 is zero, laser rays emitted from the laser section B are made to travel through the MQW optical waveguide layer 6 almost with no loss and projecting laser rays 20 can be obtained. When an electric field is applied onto the MQW optical waveguide layer 6 through a comblike p electrode 3 by applying a negative control voltage onto the terminal 1, the optical waveguide layer 6 changes in a refractive index corresponding to an inter-electrode period of the comblike electrode 3, so that a periodical diffraction grating is formed. That is, an ON-OFF action can be realized by applying a reverse bias voltage onto the terminal 1 or not.

Title: Method and apparatus for measuring impedance characteristics of crystal oscillator
Inventor: ARAKAWA NORIO
IPC: G01R27/02
Filed: 1995-03-13
Abstract: PURPOSE: To suppress error in the calculation of resonance frequency by determining the linear relationship among the reactances of a complex impedance calculated from data measured with a plurality of frequencies thereby decreasing the number of measuring points. CONSTITUTION: Measurements at two frequencies are converted into complex impedances and a linear function passing both reactance points is calculated thus determining a resonance frequency f0 at a point where the linear function intersects the reactance value = 0. Measurement data is picked up at two points or more at a wide frequency interval 410. In case of two measuring points 402, 403, where the measuring points N=2, the line of reactance value = 0 exists between the points 402, 403. A crystal oscillator exhibits high linearity and a line 400 passing these two points is determined. The resonance frequency f0 is determined at a point where the line 400 intersects the line of reactance value = 0.

Title: Cache memory invalidating control system
IPC: G06F12/08
Filed: 1992-04-02
Abstract: PURPOSE:To transmit an invalidating request only to a data processor to which an invalidating processing is necessary by using a table which displays a memory reference situation by a data processor. CONSTITUTION:The table which displays the memory reference situation, and the table which displays the situation commonly referred to by data processors 10, 11, and 20, are provided in a memory controller 40. For example, at the time of operating a writing operation to a memory through a bus 30 to a memory block registered in the cache memory of the CPU 10 by the CPU 11 or the input and output interface 20, the memory controller 40 transmits an invalidating request signal 310 to the CPU 10, and transmits an invalidation address to the bus 30. The CPU 10 fetches the address, and invalidates the memory block of the cache memory. On the other hand, at the time of operating the writing operation to the memory block which is not registered in the CPU 10, the memory controller 40 doesn't transmit the invalidating request signal 310.

Title: Four-wheel drive vehicle
Inventor: YOSHIDA SHIGEYUKI
IPC: B60W10/12
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To execute changeover of a driving mode appropriately according to travel resistance by switching a driving state suitably from a two-wheel drive state to a four-wheel drive state when the travel load quantity of a vehicle is larger than the specified value. SOLUTION: In case of switching a driving mode command from a two-wheel drive mode to a full-time four-wheel drive mode, judgment based on vehicle speed V (S52), judgment based on the absolute value |ΔVC| of propeller shaft rotation difference (S56), judgment on whether travel load resistance fV is larger than the specified value fV1 (S60), judgment based on a rough road degree (akuro) (S64), judgment based on a sporty degree (sport) (S68) are made, and whether shift is possible is judged. Since the travel load resistance fV is made a discrimination condition, in case of the vehicle traveling on the road surface of large travel resistance, changeover from the two-wheel drive mode to the four-wheel drive mode can be made on the basis of a driving mode command corresponding to the traveling state of the vehicle.  The actual driving mode is therefore switched from the two-wheel drive mode to the full-time four-wheel drive mode satisfactorily with good responsiveness.

Filed: 1985-04-17
Abstract: PURPOSE:To prevent speed change shocks by changing over the gear stage of an auxiliary transmission of the basis of the actual speed and required output of a vehicle and the actual speed change ratio of a step-less transmission. CONSTITUTION:An auxiliary transmission 14 is changed over from the low speed gear stage to the high speed one when the speed change ratio r is smaller than a predetermined value r(theta) and a predetermined value rO or r(v).
