CONSTITUTION:A time interval m0, between the first two continual transfer pulses, following a synchronizing signal A, outputted by a zero cross detection circuit 64, is assumed to be the effective storage time, and the electric charge, stored during this, is read out at the time interval l0 between the next transfer pulses B(2) and B(3). A controlling means 48 regards only an information, transferred by the pulse B(2), to be an effective output signal (0), and adopts it, and rejects the output signal (0), transferred by the other pulse. When for instance, the signal (0), for respective picture element, exceeds the prescribed maximum value, the controlling means 48 makes m0 decrease by decreasing the signal to show the time m0 to be set in a counter 76, and makes a light exposure decrease. Above mentioned time interval l0 is set longer than the minimum time, required for a standard time set circuit 68 to output a stored charge as the signal (0).

Title: Ultrasonic sensor
Inventor: TAKAGI TOSHIMASA
IPC: G01S15/04
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To enable detection of an invading object by a method wherein an arrival time is compared between the reflected light during monitoring and the reflected light during environmental setting to judge that an object exists in a monitoring space when the former is shorter than the later and the value of the later exceeding a fixed value is assumed as the fixed value. SOLUTION: An oscillation signal of an oscillator 1 is transmitted by a transmitting circuit 2 as tone bust wave from a transmitting/receiving device 3 and the reflected wave from an object within a monitoring space is received by the transmitting/ receiving device 3. The received signal is detected by a detection circuit 5 via an amplification circuit 4 to measure the time until a detection waveform exceeds a fixed threshold after the transmission of an ultrasonic wave. In the environmental setting for a environment memory circuit 7 and a present state memory circuit 6 separately, the arrival time of the reflected wave during the monitoring is always stored to compare the individual arrival time of the circuits 6 and 7 by a comparator circuit 8. A detection judging circuit 9 determines an object to exist when the arrival time of the circuit 6 is shorter than that of the circuit 7.  When the reflected wave is not received by the arrival time delayed the most within the monitoring range in the environmental setting the arrival time is judged to be such of the circuit 7.

Title: Objective hologram lens for optical head
Inventor: YANAGI SHIGETOMO
IPC: G11B7/135
Filed: 1987-02-13
Abstract: PURPOSE:To prevent the position shift of a focal point due to the change of the wavelength of a laser beam from being generated and to surely perform the tracking of a servo mechanism, by confronting refracting hologram lenses with specific intervals against those of condensing holograms. CONSTITUTION:In an optical head constituted of a laser diode 10, the hologram lenses 2-9, and an optical detection circuit 11, when the wavelength changes by the mode hop of the diode 10, the focal point comes off a targeted track on an optical disk 1. To prevent the shift, the specific interval is provided between the objective and the condensing holograms 4 and 2. In other words, assuming the interval between the lenses 2 and 4 as X, and that a position passing on the lens 2 is shifted by D when the wavelength lambda of a beam of light being made incident on the lens 4 at a refraction angle theta1' is changed by DELTAeta, the lenses 2 and 4 are arranged so as to satisfy an equation D=X (DELTAetasintheta1')/(eta+DELTAeta). In such a way, it is possible to prevent the position shift of the focal point from being generated, and to perform track servo and focus servo.
