Title: Cycle measuring circuit
Inventor: NINOMIYA NORIO
IPC: G04F10/04
Filed: 1989-05-16
Abstract: PURPOSE:To obtain data which are close to cycles speedily even when the cycles of an input pulse signal become abnormally long by outputting a set value from an output means when detecting count data reaching a set value. CONSTITUTION:A counter 1 measures a constant-cycle clock in every cycle of the input pulse signal and outputs digital data corresponding to the cycles of the input pulse signal. Then, when a detecting means 2 detects the output count data of the counter 1 reaching the set value, an output means 3 outputs the set value of the output count data of the counter 1 as output digital data with the output of the detecting means 2. Consequently, even if the input pulse signal exceeds cycles corresponding to the set value, the set value which is closest to the cycles is obtained immediately.

Title: Motor drive controller for motor-driven bicycle
Inventor: MATSUBAYASHI TORU
IPC: B60K1/04
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To provide a function for detecting abnormalities in the circuit of a depressing force detecting means (torque sensor). SOLUTION: This controller has a motor 1 for auxiliary power, a torque sensor 2 for detecting torque by the difference between the motor and depressing force, and a controller 4 for controlling the motor 1 according to the sensor output. The torque sensor 2 has a main signal detecting part 11 for outputting main signal VM increasing according to the torque and a sub-signal detecting part 12 for outputting sub-signal VS decreasing according to the torque between a power source Vcc for operating the torque sensor 2 and a grounding terminal GND.

Title: Sinusoidal wave fm modulation signal generator
Inventor: SAGUSA ISAO
IPC: H03C3/00
Filed: 1986-05-28
Abstract: PURPOSE:To stabilize a group delay characteristic and an output level and to reduce the modulation distortion factor by forming a aquare FM modulation signal from a modulation signal in an audible frequency, dividing the signal into a fundamental wave, the 2nd and 4th harmonics and adding the signals via a resistor respectively as 2-system combined signals so as to eliminate the harmonics, and outputting the result. CONSTITUTION:When a square voltage controlled oscillator 22 applies FM modulation with less modulation distortion factor by using a modulation signal source 21, an output (b) is a square wave FM modulation signal. The signal (b) is fed to a frequency divider 23 and a synthesizer 24 and a signal shown in figure is obtained at the output of an operational amplifier 27. In setting the resistance ratio of registors 25, 26 properly, harmonics from the 2nd to the 6th are not included in signals f, g. Since the amplitude depends on the output of the synthesizer 24 and the resistance of the resistors 25, 26, the amplitude is constant independently of the quantity of modulation. In supplying a signal (h) from the operational amplifier to a low pass filter 28, the output goes to a sinusoidal wave FM modulation signal (i) with less modulation distortion factor whose group delay characteristic output level is stable and the result is outputted from an output terminal 29.

Title: Method for reducing wired or-glitch of high-performance bus design
Inventor: YUAN LEO
IPC: G06F3/00
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To decrease wired glitches and improve a bus speed by making it possible to settle a wired OR glitch only in a time for one propagation delay so that a bus can correctly be sampled. SOLUTION: The bus 3 is connected to a power source 1 through terminating resistors RT2 at both its end parts. A turning-on driver 6 and a turning-off driver 7 are connected to the bus. The drivers 6 and 7 are connected to the buses through resistors Rs 5 and Rs 4. The resistors Rs 5 and Rs 4 have the same resistance value. While the turning-off driver 7 turns off, the turning-on driver 6 turns on and generates a negative-directional varying voltage wave 9, which is propagated along the bus away from the turning-on driver 6. The driver 7 generates a positive-directional varying voltage wave 8, which is propagated away from the driver 7. The rise and fall times of those voltage waves 8 and 9 are controlled to reduce the wired OR glitch.

Title: Measurement of width
Inventor: OGURA YUKIO
IPC: G01N29/44
Filed: 1984-06-16
Abstract: PURPOSE:To facilitate measurement of the width of an object, by obtaining the height of a scattered wave echo at each end of an object for measurement by the use of an ultrasonic beam. CONSTITUTION:When an ultrasonic beam is projected from a probe 4 toward an internal defect 2, there are produced a scattered wave echo 6 at the upper end 5 of the defect 2 and a scattered wave echo 8 at the lowe end 7 of the defect 2. The narrower the width of the defect 2, the smaller the height of the echo 6, and the larger the height of the echo 8. The wider the width of the defect 2, the larger the height of the echo 6, and the smaller the height of the echo 8. Accordingly, various widths for the internal defect 2 of a test specimen 1 are set, and an echo height ratio is obtained from a given formula on the basis of echo heights corresponding to the set defect widths, whereby correlation between echo height ratios and defect widths is obtained. This correlation exists independently of the material of the specimen 1 or the height of the internal defect 2. Accordingly, a defect width is readily obtained from the correlation.

Title: Bus control method
Inventor: KONDO NOBUKAZU
IPC: G06F13/12
Filed: 1992-05-15
Abstract: PURPOSE:To improve the bus use efficiency by reducing the overhead of data transfer. CONSTITUTION:A module (master) 100 accesses a module (slave) 101 for read requests the bus use right to a bus arbiter by a signal BREQ 61 and transmits it by a signal LC 63 that the next cycle is the last cycle to be used by the master. When the master 100 is permitted to use a bus by a signal RGRANT 62, the master 100 transfers the address to the slave 101 in the next cycle by a signal A/D 50 of the system bus to start the read access and resigns the bus use right. Only when the slave 101 cannot accept the transferred address, the slave 101 asserts a signal RETRY 55 two cycles after the transfer cycle of this address. The module 100 which executed transfer two cycles before the cycle where the signal RETRY 55 is asserted executes this transfer again.
