Title: Rotary electric apparatus
Inventor: KAKIUCHI TAKEO
IPC: H02K5/20
Filed: 1993-11-02
Abstract: PURPOSE:To reduce pressure loss through ventilation to allow increase of amount of wind by providing a window to a frame and exhaling a cooling wind from the window of the frame or bracket. CONSTITUTION:A frame 41 is provided with windows 16, 17 for exhaust at the locations respectively near an exhalation bracket 5 and an air intake bracket 6. A cooling air absorbed from a window 8 enters a ventilation path 44 cooling a rotary electric apparatus and is partly exhaled from the window 17. The remaining air cools an iron core 3 of stator and is partly exhaled from the window 16. The remaining cooling air is exhaled from the window 7. Therefore, exhalation is carried out through the window 5 of the bracket and windows 16, 17 of the frame 41 and a total exhalation area is larger than that of only the window 7. Thereby, the cooling characteristic of a rotary electric apparatus can be improved by lowering a pressure loss is the exhalation and increase in amount of cooling air absorbed from the window 8.

Title: Starter of synchronous motor
Inventor: HIGUCHI SATORU
IPC: H02P1/52
Filed: 1984-12-28
Abstract: PURPOSE:To compensate the phase difference displacement of a synchronous motor in an input zero time to a synchronous motor immediately before converting to a power supply path by providing a phase regulator for arbitrarily setting input/output phases in a synchronization detector. CONSTITUTION:A variable frequency power source 5 is first controlled to be accelerated to a synchronous motor 3 to a rated speed. Then, the fact that the voltage, frequency and phase difference between an AC power bus 1 and a starting bus 7 fall within the prescribed range is detected by a synchronization detector 10 to close a system switch 2. Here, the phase regulated value of a phase regulator 11 is set to the value of the internal phase difference displace ment of the motor 3 obtained in advance by a flywheel effect coefficient of the load of the motor 3 and the input zero time of the motor 3. Thus, when the switch 2 is closed, a rush current is not flowed to the motor 3.

Title: Ignition timing controller for internal combustion engine
Inventor: SASAKURA HACHIRO
IPC: F02P3/045
Filed: 1986-11-19
Abstract: PURPOSE:To improve the ignition timing precision even in the case when the conduction time is made longer than the ignition cycle by executing the processing for the ignition timing in preference to the processing for the conduction starting time and setting the mask time at that time so that the conduction starting timing is made larger than the ignition timing. CONSTITUTION:A microcomputer memorizes the processing angle signal obtained through the calculation of the ignition time and the conduction starting time and the delay time from the processing signal into a memory means. An output treatment execution means executes the output processing if the present angle position accords with the discrimination signal of the treatment angle when the interruption of the angular pulse is generated. In the output treatment, the processing of the ignition timing is executed in preference to the processing of the conduction starting time, and a mask time calculation discriminating means sets the mask time for the program processing delay for the execution of the output treatment into two stages, and calculation-discriminates the discrimination of the conduction processing angle by using the larger mask time.

IPC: G03G15/01
Filed: 1987-11-02
Abstract: PURPOSE:To obtain a color copied image which is more faithful to an original and pleases a user's fancy by making it possible to adjust color separation characteristic in itself at the time of separating the color of the original image and exposing it. CONSTITUTION:When the angles of multilayer thin film interference filters 21-23 functioning as spectral means are changed, light which executes scanning and exposure is refracted by said filters according to the change of the angles to change an optical path. When the optical path for scanning and exposing the image of the original 1 on a photosensitive drum 9 is made different because of the color of light whose color is separated, a toner image finally transferred on a transfer sheet is deviated and color slurring occurs in a copied image. Then the optical path is corrected corresponding to the change of the angles of the multilayer thin film interference filters 21-23 by an optical path correction glass 26 functioning as an optical path correction means, so that the images of all the colors are made to be exposed in the same position of the photosensitive drum 9. Since it is made possible to adjust the color separation characteristic in itself at the time of separating the color of the image of the original 1 and exposing it, the adjustment of the hue which is more faithful to the original and pleases the user's fancy can be performed.

Abstract: PURPOSE:To clearly bring a target voice to sound recording by reducing a wind cutting sound by using two or more pieces of microphones whose sensitivity to the wind cutting sound is different, and detecting whether the wind cutting sound exists or not by a difference of output signals of the microphones. CONSTITUTION:A microphone 1 whose sensitivity to a wind cutting sound is high, and a microphone 2 whose sensitivity is low are given to a mixing circuit 5 through voice circuits 3, 4, and mixed, based on a control signal S1 of a control circuit 14. A mixed output is selected by a control signal S2 by a switching circuit 7 through an HPF 6 or a direct path, and sent to a sound recording circuit system. Also, from outputs of the voice circuits 3, 4, a low-pitched sound area being a main frequency component of the wind cutting sound is extracted by LPFs 9, 10, detected converted to a DC voltage by detecting circuits 11, 12, and thereafter, inputted to a comparing circuit 13, and when a level difference exceeds a prescribed value, it is discriminated that the wind cutting sound exists. When the wind cutting sound exists, the control circuit 14 generates a signal S1 and raises an output ratio of the microphone 2, generates a signal S2 and switches a switching circuit 7, and attenuates and outputs a wind cutting sound component through the HPF 6. As a result, even under a strong wind, sound recording can be executed satisfactorily.
