Title: Drive control of dd motor
Inventor: SENO KOICHI
IPC: H02P6/182
Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To curtail the number of parts, and to increase efficiency of chip mounting by changing over the state of the currents of three-phase coils, on the basis of the polarity of electromotive force induced in a coil in a high- impedance state from among the three-phase coils. SOLUTION: Transition from a south pole to a north pole of a main magnetic pole being opposed to a U-phase coil 601, in a state (1) in which a current I is caused to flow from a W-phase coil 603 to a V-phase coil 602 through a neutral point N, for example, is detected on the basis of the polarity of electromotive force induced in the U-phase coil 601 which is in a high-impedance state. Consequently, the state of the current I caused to flow in the coils 601-603 is changed from the state (1) to a state (2). Following this, similar operation is performed. Namely, an output state is changed over, on the basis of the polarity of electromotive force induced in a coil in a high impedance state, from among the three-phase coils. Accordingly, a Hall element for detecting rotor position becomes unnecessary, and the number of parts is curtailed.  Consequently, the efficiency of chip mounting can be improved.

Title: Serial communication equipment
Inventor: USHIO YUKIHIDE
IPC: H04L12/28
Filed: 1990-02-23
Abstract: PURPOSE:To attain high speed transmission and to prevent an external interference data from being processed in mistake into a data by providing a means inhibiting data transmission during the reception and a means inhibiting the data transmission when the error in the reception data is detected. CONSTITUTION:When a transmission serial data signal is outputted from an EXOR circuit 212, it is outputted serially as a transmission data via an AND gate 213. However, the presence of an output of the transmission data is controlled by using a signal 1 in the figure. The signal 1 goes to a low level when it is discriminated as an error depending on the result of comparison of a comparison selection circuit and the result of an error detection circuit 7 to interrupt an output of the transmission data. Moreover, the signal goes to a high level only when an 8-bit shift register 16 is shifted out by a timing generating circuit 3 to permit the output of the transmission data. Thus, the transfer is comparatively made high and it is prevented that an external interference data is processed in mistake into a data.

IPC: G01R29/22
Filed: 1991-03-11
Abstract: PURPOSE:To enable overall evaluation of the material quality of a surface acoustic wave board and thereby to increase the precision of evaluation by disposing four or more sets of paired inter-digital electrodes in a scattered manner on a piezoelectric body with which a sample board is brought into close contact and by measuring the material quality by each set thereof. CONSTITUTION:A piezoelectric body 11 is set on a holding stage 7 and a sample board 2 is superposed on the body and brought into close contact therewith by negative- pressure suction to holes 15 by a vacuum pump. Thereafter an excitation voltage is impressed on one of paired cross finger electrodes 11A and 11B from a measuring means and a voltage output from the other is measured. At this time, a surface acoustic wave is generated from the excitation side, propagated through the board 3 and taken out as an electric signal from the other electrode. In other words, direct propagation of the surface acoustic wave through the piezoelectric body 11 is checked by checking grooves 12. Besides, it is propagated only between the inter-digital electrodes in a set and propagation to other sets is checked by a sound absorbing material 13. Measurement is conducted sequentially in regard to four sets of the inter-digital electrodes and evaluation of the material quality at four places of the board 3 is conducted.
