Title: Optical disk device
Inventor: ISHIBASHI HIROMICHI
IPC: G11B7/12
Filed: 1983-12-29
Abstract: PURPOSE:To almost eliminate the fluctuation of tracking error signals against a turning angle to make high-speed operations of an optical disk device possible, by successively providing the 1st and 2nd reflecting members in one line along the optical axis and putting the 2nd reflecting member on the axis of the turning shaft of a turning member, and then, optically coupling the 2nd reflecting member with the main body of the optical system. CONSTITUTION:Beam of the same direction coming from optional two points (p) and (q) to one track T of an optical disk is reflected by the 1st reflecting member 2a and 2nd reflecting member 2b and advance to the main body 4 of an optical system after passing through a light transmitting member 3. Since the 1st and 2nd reflecting members 2a and 2b are parallel with each other, lines pa-qa and pb-qb are also parallel with each other. Therefore, the line pc-qc connecting images of two poins viewed from the bottom section of the 2nd reflecting member 2b is parallel with the line p-q connecting two pints p and q. Moreover, this does not relate with the turning angle theta0 of a turning member 6. Since the turning angle theta0 does not appear on a split photoreceptor 4e, uniform tracking servo can be performed from the innermost periphery to the outermost periphery on an optical disk.

IPC: G01J5/08
Filed: 1986-10-23
Abstract: PURPOSE:To enhance the capacity of a radiation meter without using a chopper, a buffle and a blackening iris, by placing a detection element in the vicinity of the spherical surface of a concave mirror having a hole opened to the center thereof and allowing signal light to be incident to a detector through the hole. CONSTITUTION:A detection element 1 cooled by a cryogen is placed in the vicinity of the center of the spherical surface of a concave mirror 4 having a hole opened to the center thereof and an external signal light is looked from the hole as an iris. The visual field other than the hole comes to look the mirror image in the periphery of the element 1 itself held to a low radiation level cooled by the reflecting effect of the concave mirror. The concave mirror is placed at a place sufficiently spaced apart from the element to make an emitting pupil clear and the end parts of FOV and the element from a planning aspect becomes small in the difference with an actually looking visual field and the visual field outside FOV looks the low temp. region around the element 1 itself and, therefore, a stray light level becomes low. Therefore, stray light is suppressed to increase the stability of a detector and high rapidity is obtained to make it possible to prevent the omission of an image.

Abstract: PURPOSE:To quicken the operating speed by forming a differential pair with 2nd and 3rd transistors(TRs), forming a common base amplifier circuit with 1st, 4th and 5th TRs and using the common base amplifier circuit so as to converts a selected current. CONSTITUTION:TRs 3,4,5 are used to select a current depending on the polarity of a difference between the voltage of an input signal and a reference voltage inputted to input terminals 102,103. A selected current is received by the low input impedance of a common base circuit and its output is used for current voltage conversion. The input impedance of the common base circuit is a reciprocal of a mutual conductance gm of a common emitter amplifier circuit by assuming a common base current amplification factor a of the TR to be nearly equal to 1. That is, an input capacitance Cin of the common emitter amplifier circuit is expressed as Cin=Cin (1+gm/gm), no mirror effect is caused, the charge/discharge time of the input capacitance by the input signal is reduced. Thus, the operating speed is quickened.
