Title: Reflecting mirror of headlamp for vehicle
Inventor: NINO NAOAKI
IPC: F21V7/09
Filed: 1992-02-04
Abstract: PURPOSE:To provide a central region of brightness by vividly forming a cut line that is specific for a low beam without generating glaring by effectively using the entire surface of a reflecting surface, and by focusing a filament image on a limited region under a horizontal line. CONSTITUTION:A reflecting surface 1 is formed out of three reflecting region groups around an optical axis. First reflecting region groups 29A, 29D approach a horizontal surface including the optical axis, and the surface shape forms the rotational parabolic surface of a focal point F. The reference surface of each second reflecting region group 29B, 29E is a complex of cross lines, by which a virtual parabolic surface having a reference parabolic line in the horizontal surface tilted at a cut line angle theta to the horizontal surface including the optical axis, and having a focal point at a point on an optical axis that is different from the focal point F to a certain point on an orthogonal projection for the horizontal surface of the reference parabolic line, at a vertical surface including the optical axis. Third reflecting region groups 29C, 29F form surface where theta=0 in the reference surface. A focal point E of upper regions 29B, 29C of the horizontal surface including the optical axis is in the side of a top O, outside of the focal point F. A focal point D of lower regions 29E, 29F is in the reverse side of the focal point E sandwiching the focal point F.

Filed: 1984-03-13
Abstract: PURPOSE:To prevent deterioration in the resolution due to misconvergence by adopting substantially one beam at a small signal region of a video signal in the two-beam system. CONSTITUTION:Cathode currents Ik1, Ik2 are applied to red/green/blue signals R, G, B via nonlinear circuits 41, 42 respectively in picture tubes IR, IG and IB and they are changed symmetrically respectively as logarithmically and exponentially. Thus, the cathode current Ik2 hardly flows at the small signal region and the beam is one substantially. The cathode currents Ik1, Ik2 flow symmetrically at a large signal region and symmetrical two-beam system is attained.

Title: Detector
Inventor: SHIMADA KOUJI
IPC: G01F1/10
Filed: 1980-04-11
Abstract: PURPOSE:To detect the movement of a mechanism part that makes rotating or linear motion accurately by using light for a signal transmission medium and an optical switch responding to magnetism to a detector. CONSTITUTION:A rotator 33 which rotates at the speed proportional to the flow rate of the fluid flowing in a piping 31 is disposed with a magnet 34 on its periphery. An optical switching element 37 connects the continuous light from a light source 36 inputting via an optical transmission line 35 to an optical transmission path 38, when the magnet 34 approaches and intercepts the passage of the continuous light to the transmission path 38 when the magnet 34 goes apart. Hence, the  intermittent light of the period proportional to the rotating speed of the rotator 33 is obtained on the output side of the transmission line 35 and the flow rate is measured by counting this. In this way, the flow rate is detected accurately without being affected by induction faults and disturbances. This is similarly adaptable to a linearly moving body as well.

Title: Program initializing system
Inventor: KOUNO HISAO
IPC: G06F11/16
Filed: 1982-03-26
Abstract: PURPOSE:To obtain a high-reliability and economical program initializing system, by transmitting an abnormality signal to an alternate external storage device or an emergency controlling circuit when an external storage device for initialization becomes unoperatable. CONSTITUTION:An emergency controlling circuit EMA monitors operation states of current and stand-by processing devices PR0 and PR1 connected to main memories MM0 and MM1. When the circuit EMA initializes programs of memories MM0 and MM1 in case that a magnetic tape device MTU0 for initialization and a tape controller MTC0 are normal, the circuit EMA starts a program initializing mechanism IPL0 and uses the device MTU0 by an incorporated channel IOA0 to perform the initialization. When the device MTU0 or the controller MTC0 becomes unoperatable, the controller MTC0 transmits the abnormality to a tape controller MTC1. The controller MTC1 changes the channel of an alternate magnetic storage device MTU1 to the channel IOA0. Thus, the mechanism IPL0 uses the device MTU1 to perform the program initializing operation.
