Title: Electromagnet power supply device
Inventor: KAWAKAMI NORIKO
IPC: H05H7/04
Filed: 1987-10-13
Abstract: PURPOSE:To make it possible to control the power supply in a small current area when the output width instruction value of a chopper circuit is less than a specific value. CONSTITUTION:When an unnecessary voltage is applied to the load to charge an overcharge preventive capacitor 8 in a small current area, a constant current control circuit 17 makes the output pulse width instruction value smaller to decrease the output voltage. When the output pulse width instruction value decreases exceeding the minimum pulse width setting, the output signal of a comparator 21 is made '0', a chopper 7 is turned to the OFF condition, and the voltage is not applied to the load. When the standard is raised or the load current is reduced, and the voltage is again required, the output pulse width instruction value from the constant current control circuit 7 is raised, the output of the comparator 21 is made '1', the pulse is added to the chopper 7, and the voltage is applied to the load.

Title: Optical scanning device
Inventor: HAYASHI YOSHIAKI
IPC: G02B26/10
Filed: 1995-10-03
Abstract: PROBLEM TO BE SOLVED: To compactly arrange an optical system which includes a photodetecting element for synchronizing light detection by providing one lens of a scanning image forming lens, consisting of >=1 lenses, with a reflection part at a part which does not contribute to optical scanning on the scanned surface of an end part on the side where deflected luminous flux is received in a deflecting direction. SOLUTION: A lens 52 on the side of the scanned surface 6 between two lenses 51 and 52 constituting the scanning image forming lens is provided with the reflection part 10 at the part which does not contribute to the optical scanning on the scanned surface on the side of the scanned surface at the end part where the deflected luminous flux is received in the deflecting direction. Consequently, the deflected luminous flux traveling to an optical scanning area L is reflected to the photodetecting element for synchronizing light detection.  Therefore, the deflected luminous flux is photodetected by the photodetecting element 8 for synchronizing light detection prior to the optical scanning in the optical scanning area L and on the basis of the photodetection signal generated by the photodetecting element 8 for synchronizing light detection, the start points of the optical scanning are set uniformly to the lower end of the optical scanning area L. Thus, the deflected luminous flux is reflected by the reflection part to an optical deflector to reduce the size.

Title: Position and speed detecting device
Inventor: MOTOYAMA ATSUHISA
IPC: H02P29/00
Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To reduce sensitivity due to noise and enable position and speed detection with accuracy, by making a rotational position signal, calculated from an inducing signal having the frequency of an exciting signal as a fundamental wave and the exciting signal having phase difference through sum of products operation, follow phases through software PLL processing. SOLUTION: For a microcomputer 102, an arithmetic operation is performed at a position and speed detecting section 101 using timing pulses output from a timing pulse generating section as an interrupt signal. The voltage of inducing signals Vr1 , Vr2 and exciting signals Vs1 , Vs2 is input to the microcomputer 102 from A-D converters 103-106. A signal varying with a rotational frequency obtained by expressing rotational position signals Ve1 , Ve2 in first sum of products operation as rotational position θr, and subtracting an exciting frequency component from the frequency of the inducing signals, is used in the software PLL processing on the microcomputer. The rotational speed is detected by determining the change in the position detected through software PLL processing on the microcomputer 102 using a differentiation element 120.  Thus, the phase can be PLL-processed on software for a microcomputer or the like, and can be sufficiently followed.

Patent JP-S61134725-A (JP)
Title: Voltage-controllable deflector for light
Inventor: UEDA KENJI
IPC: H04N1/113
Filed: 1984-12-06
Abstract: PURPOSE:To make possible the deflection at a high frequency by applying an electric signal via each electrode to the 1st and 2nd piezo-electric elements and oscillating a reflecting mirror to change the direction of the light reflected by the specular surface on the front side of the reflecting mirror. CONSTITUTION:The piezo-electric axes of the 1st and 2nd piezo-electric elements face opposite directions and therefore the phases of the oscillation of the 1st and 2nd piezo-electric elements are opposite from each other when the electric signal is applied between the 1st electrode and the 2nd electrode. Then the reflecting mirror fixed to the electrodes in the upper part of the 1st and 2nd electrodes make seesaw motion and the deflector for the light which changes the direction of the light reflected by the specular surface is obtd. Since the piezo-electric elements are used for the oscillation source of the reflecting miror, the deflection at the speed much higher (several hundreds kHz) than the speed of the conventional deflector (tuning fork or rotary reflecting mirror, etc.) for light is made possible. The oscillation period of the reflecting mirror changes by changing the frequency of the electric signal to be impressed to the piezo-elec tric elements and therefore the control of the deflecting period of the light by the electric signal is possible.
