Patent JP-H02181608-A (JP)
Title: Manufacture of rotation detector and rotary disk
Inventor: KUROSAWA RYOICHI
IPC: G01D5/26
Filed: 1989-01-04
Abstract: PURPOSE:To realize a rotation detecting device which has high resolution by utilizing the technique of an optical disk by providing uneven radial slits which are nearly equal in width and nearly as wide as or wider than the beam diameter of a laser beam which irradiates the slits from a photodetector, on one surface of the rotary disk. CONSTITUTION:The slits 22 are projected by forming the recessed and projections which are almost equal in width on one surface of the rotary disk radially to sufficient length. When the rotary disk rotates and the laser beam 15 from the photodetector 10 reaches the position of the border of a recess and a projection of slits 22, reflected light beams are generated by both the recess and projection parts to interfere with each other, so that almost no laser light returns to the photodetector 10. When the laser light beam 15 comes to the center part of the recess or projection part of a slit 22, almost all of the laser beam is reflected by the recess or projection part to return to the photodetector 10. When the rotary disk rotates by one slit, an electric signal of two cycles is obtained and the intervals of the slits 22 are decreased to realize the rotation detector which has extremely high resolution.

Title: Zoom lens
Inventor: OTSUTOO KANTONERU
IPC: G02B15/06
Filed: 1984-01-04
Abstract: PURPOSE:To control the focal length in normal and macro ranges by using two movable lens components and providing a controller which controls the focal length in the normal range and a controller which controls macro-photographing and the focal length in the macro-range. CONSTITUTION:A lens system consists of the first fixed positive component 1, the second movable negative component 2 which changes the resultant focal length, the third movable component 3 which holds the image surface in a certain position, the fourth fixed positive component 4, and a fixed positive master lens system 5 which are arranged in order from the object side. When the third component 3 is moved to a position 3' while holding positions of the other components as they are, the lens system is focused to the object in the macro-range. When the third component 3 is moved to a position 3a and the focal length is changed additionally in the macro range, the image state is kept constant. When the second and the third components are moved to positions 2b and 3b and positions 2c and 3c, the object image on a place 6 in the macro- range is enlarged. Thus, the focal length in normal and macro-ranges is controlled.

Abstract: 813,944. Transistor amplifier and oscillator circuits. TELEFONAKTIEBOLAGET L. M. ERICSSON.: Jan. 2, 1957 [Jan. 2, 1956], No. 245/57. Class 40 (6). An amplifier, suitable for use in an oscillator and having a high input impedance comprises a first transistor arranged in an emitter-follower circuit with its output fed to the base of a further transistor having its emitter connected to the collector of the input transistor, the output of the amplifier being derived from the emitter circuit of the second transistor. In Fig. 5 the input emitter-follower transistor 1 feeds a further transistor 2 also arranged as an emitter follower and coupled to the collector of the first transistor. The collector voltage of the input transistor therefore follows the input signal and current flow between the base and collector of the input transistor is reduced thereby increasing the input impedance of the circuit. The input impedance may be further increased by connecting a capacitor between the emitter of the second transistor and a tap on the resistor Zel (Fig. 6, not shown). A yet further increase in input impedance may be obtained as shown in Fig. 7 by connecting the lower end of the emitter resistor Ze<SP>1</SP> to the emitter of the second transistor and by providing a further transistor 3 arranged as an emitter follower with its input fed from the output of the second transistor and its output coupled to the output terminal and to the collector of the second transistor. Similar circuits in which the transistors are connected in series across the D.C. supply are illustrated in Figs. 1, 2 and 3 (not shown) and in Fig. 4 In the latter figure additional feedback to the base of the second and third transistors is provided by capacitors Ce21, Ce31 and Ce32. The second transistors in Figs. 5, 1 and 2 may be replaced by transistors of the opposite conductivity type by small changes in the circuits, Figs. 8, 9 and 13 (not shown). Oscillator circuits may be formed by connecting appropriate network between output and input terminals. One suitable network (Fig. 10) comprises a circuit consisting of L1 and C1 (which may be replaced by a crystal) and two capacitors C2, C3, rectifiers L1, and L2 being provided to limit the output amplitude. In Fig. 11 the network comprises a crystal, a thermistor and a transformer while in Fig. 12 the network comprises a crystal in series with a trimming capacitor connected across two chokes, amplitude control being effected by a lamp La and a rectifier circuit L3, C5, R6. The crystal Kl can either work inductively or capacitively depending upon the setting of capacitor Ct. The lamp or a thermistor in the circuit can be fed with D.C. proportional to the oscillatory amplitude, for example by connecting it to the emitter of one of the transistors.
