Patent JP-H0447863-A (JP)
Title: Synchronizing separator circuit
Inventor: IKEDA MAKI
IPC: H04N5/08
Filed: 1990-06-15
Abstract: PURPOSE:To set a slice level optimum to the separation of a horizontal synchronizing signal and a vertical synchronizing signal by providing a transistor(TR) to the synchronizing separator circuit, in which its collector connects to an emitter of a constant current source TR via a resistor, its emitter connects to ground and its base receives a vertical pulse signal. CONSTITUTION:Since a setting value of a slice level for synchronizing separation of a synchronizing separation TR Q1 is changed by giving a vertical pulse signal to a base of a TR Q5 whose collector connects to an emitter of a constant current source TR Q2 via a resistor and whose emitter connects to a base of a TR Q5 whose emitter connects to ground so as to change a current flowing through the constant current source TR Q2 even when only a vertical synchronizing signal is attenuated, both the horizontal synchronizing signal and the vertical synchronizing signal are separated by making a slice level for a vertical fly-back period deeper than a slice level for a video signal period.

Title: Charging circuit
Inventor: SAKAGAMI MASAAKI
IPC: H02J7/00
Filed: 1987-06-24
Abstract: PURPOSE:To enable starting of motor regardless of residual capacity of a battery to be recharged, by additionally providing a circuit for feeding starting current. CONSTITUTION:Source power is rectified and smoothed then fed to a ringing choke type transistor inverter 4. A battery 1 is changed through ON/OFF of a transistor Q1. A switch 2 has contacts (a), (b), (c), where (a), (c) are connected during stoppage of a motor 3 while (b), (c) are connected during operation of the motor 3 and (a), (b), (c) are connected at starting time of the motor 3. Consequently, a resistor provided at the emitter side of the transistor Q1 exhibits lowest resistance at starting time of motor, higher resistance during motion of motor and highest resistance during stoppage of motor. As a result, duty ratio of the transistor Q1 is highest at starting time of motor, high during operation of motor and low during stoppage of motor. Since a sufficient current can be fed from a power source circuit even at starting time of motor, stable starting can be achieved regardless of residual capacity of battery.

Title: Transfer zoom lens system
Inventor: YAMAZAKI NORIYUKI
IPC: G02B15/20
Filed: 1985-07-18
Abstract: PURPOSE:To obtain a compact transfer zoom lens whose aberrations are satisfactorily corrected although a half picture angle at unmagnification is a wide picture angle with a high variable power ratio by specifying the ratio of shape factors of a lens corresponding to a stop. CONSTITUTION:The 1st-3rd lens groups and the entire lens system are moved in the optical axis direction, whereby in a full power ratio range an inter-object distance is constant and the ratio of the shape factors (q) and q' of the lens corresponding to the stop is in such relation as 0.8<qi/qi'<1.2. Provided that qi is the shape factor of the i-th lens at the object side rather than the stop, and is expressed by equation (1) where Rn is the curvature radius of the n-th plane. The qi' satisfies the shape factor of the i'th lens at the image side rather than the stop. If symmetry goes out of shape to the extent that the lens deviates from the range satisfying the conditions, the arising quantity of distortion becomes larger, and the lens can be hardly corrected by other factors.

Filed: 1987-06-24
Abstract: PURPOSE: To obtain sufficient resolving power over a wide magnification range by varying the magnification of an image by switching plural image forming lenses which differ in focal length.  
     CONSTITUTION: An image input device is so constituted that irradiating light SK from a light source 1 is projected on the color image of a color original 2 such as a color reversal film and its transmitted light HK from the color original 2 is converted by one selected image forming lens among lenses 11∼13 arrayed in a circle of a lens switching unit 10 capable of turret type switching, e.g. image forming lens 11.

Title: Optical switch
Inventor: MIKAMI KAZUO
IPC: G02B6/12
Filed: 1982-09-09
Abstract: PURPOSE:To improve switch characteristics, by preventing a light from leaking to the outside of a demultiplexing waveguide when heating bodies are heated to switch the light propagation direction to the demultiplexing waveguide side. CONSTITUTION:When a switch 17 is turned on and heating bodies 16a and 16b are heated, a temperature gradient is generated near a demultiplexing point 15 in the direction approximately orthogonal to the light propagation path, and a gradient of refractive index is generated. The light incident to a main waveguide 13 from an optical fiber 19 for input is deflected while passing the position near the maximum point of the gradient of refractive index because the heating body 16a has an arc shape, and a deflected light (h) is incident to a demultiplexing waveguide 14. In this case, since the refractive index of the main waveguide 13 is lower than that of the demultiplexing waveguide 14, a light (g) is not guided to the main waveguide 13. Though the deflected light tends to leak partially to the outside, the light which tends to leak is propagated in a high-refractive index part of the waveguide 14 because the refractive index on the inside of the waveguide 14 is higher than that of other parts by the heating body 16b and outside parts 14a and 14b form a low-refractive index clad layer equivalently by heating bodies.
