IPC: G01B7/34
Filed: 1989-10-09
Abstract: PURPOSE:To easily remove an external noise by detecting the movement of 1st and 2nd cantilevers and obtaining a difference between the signals showing the movement. CONSTITUTION:The 1st cantilever 12 provided with a probe 16 which acts on the surface of a sample and the 2nd cantilever 14 provided with a dummy weight 18 of effective mass equal to probe 16 and having characteristic frequency same as the lever 12 are provided to be close to each other. For example, the levers 12 and 14 are formed through the processes of vapor deposition and etching, etc., in a state where a silicone wafer is taken as a base with microfabrication technique. Then, the lever 12 displaces by receiving interatomic force and the external noise which act between the probe 16 and the sample. On the other hand, the lever 14 is not provided with the probe 16 which acts on the surface of the sample and it is displaced only by the external noise. Since the levers 12 and 14 equally vibrate by receiving the external noise, the external noise is easily removed by detecting the movement of the levers 12 and 14 and obtaining the difference between the signals showing the movement.

Title: Dynamic speaker
Inventor: INOUE HIDEAKI
IPC: H04R7/04
Filed: 1986-11-04
Abstract: PURPOSE:To flatten a sound pressure frequency characteristic by providing the plate diaphragm of a triangular form and a coupling cone having one end connected to the upper end part of a voice coil and the other end connected to the lower surface of the plate diaphragm. CONSTITUTION:Since the plate diaphragm 11 of the triangular form is asymmetrical with respect to a center line (j), even when the position 15 of a node generated at the time of driving the plate diaphragm 11 cannot be correctly driven by the coupling cone 16 for driving the plate diaphragm, a phase difference due to the oscillation of the respective surfaces of the diaphragm is different, so that a front room effect can be reduced. Further, the generation of the front room effect can be cancelled by the coupling cone 16 of the triangular cone form capable of driving correctly the position 15 of the node generated at the time of driving the plate diaphragm 11 of the triangular form. Thereby, the sound pressure frequency characteristic can be flattened.

Title: Speed sensorless vector control method
Inventor: KODAMA TAKASHI
IPC: H02P21/24
Filed: 1992-10-01
Abstract: PURPOSE:To provide a compensation technology at the time of instantaneous power interruption having long compensatory operation time and accompanying no instable state due to fluctuation of speed command in speed sensorless vector control. CONSTITUTION:A power interruption detecting section 23 normally monitors power supply. A compensatory operation command is outputted at a point of time when Vdc<Vref2 is satisfied after detection of power interruption. Consequently, a switch 26 is turned OFF to invalidate a torque current command Ilq* thus bringing a slip frequency command omegas to zero. A PI regulator 24 outputs a signal corresponding to drop of a detected DC voltage Vdc. That signal is added through an adder 25 to an error current DELTAIlq. A speed estimating section 11 operates an estimated speed omegar using the addition results and inverter DC voltage is controlled constant. Upon recovery of power, a power receovery detecting section 23 turns the compensatory operation command OFF. Consequently, the PI regulator 24 stops operation and the switch 26 is turned OFF. A cushion circuit 12 charges the estimated speed omegar during compensatory operation and a motor is accelerated smoothly according to the cushion.

Title: System of detecting pull-in start point of modem reception section
Inventor: MURATA HIROYASU
IPC: H04B1/76
Filed: 1985-11-22
Abstract: PURPOSE:To detect the detection of a starting point by providing the 1st detection section integrating a level of a reception signal and the 2nd detection section integrating the reception signal through a filter passing through a frequency component. CONSTITUTION:In synthesizing outputs of adders A2, A3 by an adder A4 and integrating the result by an integration device 23, the level of the integration output Y is coincident with an output X of CD detection section 15 at the detection of pi/pi, and an output Z of an adder A5 is zero. While a noise exists or the level of the line is fluctuated, since the level of the output Y is limited in terms of frequency, the level is smaller than the output X in the range of all frequencies. Thus, in catching a point when the polarity of the final output Z changes from a negative value to '0', it is discriminated at the head of a training signal and the pull-in sequencer is started correctly. Thus, the pull-in start point is detected surely at a MODEM reception section.
