Patent JP-S59117453-A (JP)
Title: Fan with electronic communication dc motor
Inventor: PIITAA MAIYAA
IPC: F04D25/06
Filed: 1983-12-09
Abstract: An electronically commutated, direct-current motor of a fan has, in a two-piece housing, a stator formed on one piece of the housing and a blade-equipped rotor attached to a shaft mounted in the housing. The rotor supports an odd number of diametrically opposed pairs of magnets which consist of permanent magnets with opposite poles. On the stator are mounted two coils positioned diametrically, a Hall element, and a diametrically positioned flux-conduction plate that faces the pole surfaces of the magnets of the rotor and is angularly offset from the coils. The Hall element senses the poles of the magnets passing by and generates an output voltage. In response to the Hall element output voltage, an electronic control circuit in the stator sends an excitation current to the coils for alternately attracting or repelling the magnets. The rotor's rotational direction is determined by the resting position of the magnets, as imposed by the flux-conduction plate associated with the coils. This fan has only a few components, is very flat, and runs very smoothly.

Title: Disconnection detector of field winding of synchronous machine
Inventor: YAMAMOTO TOSHINOBU
IPC: H02K11/00
Filed: 1988-09-19
Abstract: PURPOSE:To prevent the large damage of a rotor of a synchronous machine by inputting a field current signal and the state signal of a field winding cooling medium to output the signal equivalent to the normal temp. of a field winding as an estimated normal temp. equivalent signal. CONSTITUTION:In this disconnection detector, when a disconnection state is generated, the apparent temp. equivalent signal Tf1 calculated from field voltage and a field current becomes higher than actual field winding temp. Actual field winding temp. becomes the temp. almost determined by a field current during operation. Therefore, the continuation of the state of estimated normal temp. equivalent signal Tf2 + allowance signal Tds < apparent temp. equivalent signal Tf1 means that the ratio of field voltage to a field current (field voltage/ field current) rises to an estimated value containing allowance or more. This state means such a state that a disconnection state is generated in the circuit from a field voltage detection point to a field winding or the temp. the field winding abnormally rises surely. Therefore, the disconnection state of the field winding can be detected by this detection means and the large damage of the rotor of a synchronous machine can be prevented.

IPC: G05B19/416
Filed: 1991-09-12
Abstract: PURPOSE:To enable machining of high precision by commanding tool feed speed correctly even with the generation of sudden fluctuation in the actual speed of a spindle.

The rotating speed detected by a rotating speed detecting means afterward is corrected by this variation, and the appropriate feed speed is commanded by a feed speed control means 13. With the execution of thread cutting using such a numerical control device 10, the tool feed speed is commanded in proportion to the actual speed of a spindle motor, and even if the rotating speed of the spindle motor is lowered in the instant of a tool starting thread-cutting to a workpiece, the movement command signal of the correct tool feed speed is outputted.

Filed: 1996-09-03
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy of alignment by a method wherein the error of alignment is corrected at least on either of X and Y axial directions in the second process, and a shot error is corrected on the basis of the alignment mark in both X and Y axial direction of the first process. SOLUTION: The correction of the shot error produced when an alignment operation is conducted in process C, and the correction of the shot error produced when an alignment operation is conducted in process D are made on the data of the alignment mark in X-axis direction and Y-axis direction in process B. As a result, the correction of the shot error (shot rotational error and magnification error) can be made using the data of the alignment mark in X and Y axis directions in the same process. As a result, the correction of shot error can be made pertinently which is different from the case where the data in X-axis direction and Y-axis direction are of different processes. Accordingly, alignment accuracy can be improved to a greater degree.

Then, a buried polysilicon 7 is formed in the cavity under the active layer by an LPCVD method. Thus, the high density defective layer is removed, and generation of a leakage current can be prevented.
