Title: Optical head driving system
Inventor: KURANE HARUHISA
IPC: G11B21/10
Filed: 1986-10-17
Abstract: PURPOSE:To attain a tracking servo by converting a detected tracking error signal to a pulse signal which determines the speed and the moving direction of the step motor and controlling the step motor. CONSTITUTION:A signal component generating due to a move in the inner diameter direction of a track is detected and the DC component of the tracking error signal is converted to a positive signal in proportion to an absolute value by the aid of an absolute value amplifier 6. The output from the absolute value amplifier is inputted to a V-f converter 7 and a pulse signal whose frequency is in proportion to the tracking error signal is generated. A tracking error signal positive and negative discrimination comparator 9 discriminates whether the tracking error signal is positive or negative and drives the step motor 11 according to the step motor speed control pulse signal which controls the speed and moving direction of the step motor based on the pulse signal and according as the tracking error signal is positive or negative.

IPC: F24F11/02
Filed: 1986-10-17
Abstract: PURPOSE:To readily identify a failure and location on a display by providing a centralized control device with a display that indicates the time, operation command and monitoring lamps that indicate the conditions of respective air conditioners and a warning sound generating means that generates the failure warning sound. CONSTITUTION:The voltage of a terminal unit control circuit is evaluated by an air conditioner connecting circuit 46 of a terminal unit 2 to be fed to a micro computer 45 of the terminal unit 2, and is transmitted to the main unit 1 by a modulation/ demodulation circuit 47 through a signal wire 4. The main unit 1 receives the signal at its modulation/demodulation circuit 26, and evaluates the same by a micro computer 28. If the n-th terminal unit 2 is being operated, the operation command and monitoring lamp for the n-th terminal is illuminated, and if it is not being operated, the lamp is turned OFF. Should a failure occurs in the n-th terminal unit 2, the n-th operation command and monitoring lamp is intermittently illuminated, and the failure is specified by indicating an alphabetical symbol, for instance, on the display along with the warning sound by a warning sound generating circuit 31. By means of a timer circuit 49 of the main unit 1, the ON-OFF operation of the terminal unit 2 is performed.

Abstract: PURPOSE:To reduce the number of element and to simplify the constitution so as to reduce the manufacturing cost of an image reader, by selectively leading image information recorded on a reflective or transmissive original to a common reading optical system by means of the switching operation of a movable mirror. CONSTITUTION:If an original S is reflective one, reflecting light L1 from the image information recorded on the original S is made incident on the reflecting surface 50a of a 2nd mirror 50 through the slit between scattering plates 40 and 42 after it is made incident on and deflected 90 deg. by the reflecting surface 48a of a 1st mirror 48. Then the reflecting light L1 reflected by the reflecting surface 50a is reflected by the reflecting surface 52a of a movable mirror 52 set in parallel with the reflecting surface 50a and forms an image in a CCD 58 through a condenser lens 56. When the original S is transmissive one, light, L2 transmitted through the original S is made incident on the reflecting surface 60a of a 3rd mirror through an original platen 32 of a transparent body. The light L2 is deflected 90 deg. by the reflecting surface 60a and made incident on the reflecting surface 62a of a 4th mirror 62 where the light L2 is again deflected 90 deg., and then, reaches the movable mirror 52. Since the reflecting surface 52a is turned 90 deg., reflecting light L2 is reflected by the reflecting surface 52a and forms an image in the CCD 58 through the condenser lens 56.

IPC: G06F12/00
Filed: 1994-09-19
Abstract: PURPOSE: To provide a hypermedia document communication equipment which can perform an effective pre-read operation with high responsiveness. CONSTITUTION: A button/link history updating part 1c of a hyper document display terminal 1 stores the data whose using frequency is automatically updated to a scene to which a document display request is given.
