Title: Optical scanner
Inventor: ABE FUMITAKA
IPC: G02B26/12
Filed: 1984-02-29
Abstract: PURPOSE:To relax the manufacture precision of a rotary polygon mirror extremely by correcting the large tilt extent of mirror surfaces of the rotary polygon mirror. CONSTITUTION:Angles of incidence between respective incident beams 2a-2c and a reference incidence beam are denoted as DELTAthetaa-DELTAthetac, and they have angle difference DELTAtheta0. Then, the respective beams form images at three points which are mutually fDELTAtheta0 different, i.e. Oa-Oc. Further, there is deviation DELTAtheta in the tilt angle of the polygonal mirror 1 and deviation 2fDELTAtheta is generated on an image plane. The image plane position (h) is as shown by an equation when a beam 2 having difference DELTAthetai from the reference beam is scanned on a surface DELTAtheta on the basis (h=0) of the image formation position when the reference incident beam is DELTAthetai=0 (i=a, b, and c) and the tilt angle is DELTAtheta=0. Namely, such a beam that h=0 has no position deviation on the image plane 4 and this is attained only on the condition that DELTAtheta'=0 and DELTAthetai=-2DELTAtheta.

Title: Control circuit of ac motor
Inventor: TADOKORO TAKEO
IPC: H02P23/07
Filed: 1986-02-26
Abstract: PURPOSE:To prevent free falling of a load in a crane or the like, by a method wherein a power source is provided separately from a control power source, and the length of initial current rising time of the control winding of a saturable reactor is eliminated. CONSTITUTION:In a control circuit having control power source A-C and controlling the winding-up or winding-down of a load W, the control of the control power source B is performed when the load W is wound down, and an electromagnetic brake MB is used at the stop state. In the case of a crane, however, the stop torque of only the electromagnetic brake MB is not sufficient and the rotational force in U-direction must be temporarily given to an induction motor IM. However, if the control of the control power source B is stopped and then the control of the control power source A is started, lag exists in rising of control current by the control power source A. Consequently, the power source C is installed separately from the control power source A, thereby a definite current corresponding to the initial current is normally given to the control winding of reactors X1, X2, X3 at winding-up side.

Title: Rear projection type image receiver
Inventor: YANAGI HARUYUKI
IPC: G03B21/00
Filed: 1990-02-22
Abstract: PURPOSE:To obtain a compact rear projection type image receiver by arranging a polarizing beam splitter on a projection optical path between a lambda/4 optical phase plate and a screen. CONSTITUTION:By setting the plane of polarization of image light to S polarization, the image light projected through a projecting lens 4 is reflected and made incident on the lambda/4 optical phase plate 9 and a second total reflecting mirror 10 when it is made incident on the polarizing beam splitter 6. At this time, it is transmitted through the phase plate 9 first and reflected on the mirror 10. Then, since it is transmitted through the phase plate 9 again after it is reflected, the plane of polarization of the image light is rotated by 90 deg. and it becomes P polarized light. Besides, it is made incident on the splitter 9 again. In such a case, since the image light is the P polarized light, it is transmitted through the splitter 6 and projected on the screen 2 thereafter. Thus, the projection optical path is effectively overlapped and the image receiver is made compact.
