Title: Detector for light projection signal
Inventor: TSUNEKAWA TOKUICHI
IPC: G01S17/02
Filed: 1984-07-31
Abstract: PURPOSE:To detect a reflected light from an object with a high precision even if a quantity of ambient light is varied, by alternating a projection-nonprojection cycle and the nonprojection-projection cycle of a light projecting means by a light projection control means. CONSTITUTION:A control pulse CF2 controls a projected luminous flux, and the high level indicates the light projection state, and the low level indicates the nonprojection state. An ambient light quantity PA2 changing with time indicates that the quantity of ambient light is constant with respect to time, and period from a time t20 to a time t21 is a projection section, and the period from the time t21 to a time t22 is a nonprojection section, and the period from the time t22 to a time t23 is a nonprojection section, and the period from the time t23 to a time t24 is a projection section. Since the projection-nonprojection cycle, and the nonprojection-projection cycle are alternated in this manner, a true light projection signal as the difference between an integral signal for projection and that for nonprojection is detected with a high precision when the quantity of ambient light is not only constant but also varied as shown by PD2. Thus, the drift of an output signal ID2 at times t22 and t24-t27 is reduced.

Title: Subminiature high-frequency crystal tuning fork
Inventor: KONNO TADASHI
IPC: H03H9/215
Filed: 1978-12-28
Abstract: PURPOSE:To obtain a high-frequency crystal tuning fork of the low-frequency band of bottom relative displacement, by cutting off the inside corner at the tip of an arm by using the secondary resonance mode of a subminiatue crystal tuning fork. CONSTITUTION:In the arm tip length direction of a subminiature turning-fork type crystal vibrator for a timepiece, a groove of P1 in length and q1 in width is provided and its tip inside corner is cut off at cutting-off angle (theta) for experimentation for bottom relative displacement in the secondary mode. In the figure showing the result, the lateral axis represents the position of a tuning-fork bottom end serving as a crystal tuning-fork support, and the longitudinal axis relative displaement UYn'/ U0 in the arm length direction, showing the function of ratio deltaM/M of total mass M of half the tuning-fork section to arm-tip inside cutting-off mass oM for the outward movement of the center of gravity of the arm. According to this, the relative displacement lessens as deltaM/M increases from deltaM/M=0 (curve #0), and between curves #2 and #3, UYn'/Uo 0 is obtained, so that the high Q value of a tuning fork making use of the secondary mode can be realized. Therefore, a high-frequency crystal tuning fork basing upon a stable and subminiature low- frequency vibrator can therefore be obtained.

Title: Photoelectron integrated circuit
Inventor: TATO NOBUYOSHI
IPC: H01L27/15
Filed: 1991-07-02
Abstract: PURPOSE:To provide a light receiving simply to be manufactured OEIC which minimizes noise, and reduces the generation of heat and the consumption of power. CONSTITUTION:By applying positive or negative voltage to this bias electrode, a horizontal type light receiving device 12 is made capable of confining both carriers optically generated in a light receiving layer into its interior or taking out one party of carriers and controlling the sensibility of the device. The output of the horizontal type light receiving device 12 is input into a level detection circuit 18 so that it may be possible to obtain a flattened voltage signal. This voltage signal is reversely amplified in a bias amplifier circuit 20 and enters a bias electrode as bias voltage. When the average level of the detection signals rises and drops, depending on the strength of optical pulses which enter the horizontal type light receiving device 12, the bias voltage which enters the bias electrode is reduced and increased accordingly. It is, therefore, possible to increase and reduce the sensibility based on the operating characteristic of the horizontal type light receiving device 12 and carry out automatic gain control(AGC).

Title: Variable gain amplifier
Inventor: YANAGISAWA KIYOUTAROU
IPC: H04B1/10
Filed: 1995-06-28
Abstract: PURPOSE: To eliminate the need of a SW(switching) circuit and to dissolve switching noise at the time of mute by providing a mute control means for turning the input voltage of a control circuit to a prescribed voltage by the on/off signals of the mute. CONSTITUTION: The control circuit 1 compares a voltage inputted from a terminal P1 with an internal reference voltage and converts it to a current corresponding to the difference. The current is converted to the voltage again by an internal diode and the voltage is supplied to a gain amplifier circuit 2. The gain amplifier circuit 2 amplifies signals inputted from the terminal P2 corresponding to the voltage obtained in the control circuit 1 and outputs them to the terminal P4. The mute control means is composed of the serial circuit of a diode D3 and a transistor Q1. At the time of the mute, by turning ON the transistor Q1 by a control voltage from the terminal P3 and controlling the input voltage of the control circuit 1, the gain of the gain amplifier circuit 2 is minimized.  Thus, an output level difference caused by output DC components from the SW circuit is not present and the generation of the switching noise is suppressed.

Abstract: PURPOSE:To simplify constitution, by linking a ratchet with the driving shaft of a power source through a speed change gear and suppressing the rotation of this ratchet by a constant-speed mechanism consisting of a flywheel. CONSTITUTION:When an original and recording paper are set on an infrared-ray transmittable substrate and pressed with a presser lid, an optical system 24 is set at a home position and at the same time, the spiral spring of the power source 19 is wound and locked. When a switch is depressed, the lamp 25 of the optical system 24 turns on and after the light emission of the lamp 25 becomes stable, the switch is further depressed to unlock the power source 19. Once the power source is unlocked, the driving shaft is rotated by the spiral spring of the power source 19, so the constant-speed device operates to make the rotation of the driving shaft constant. Consequently, a guide 21 moves along a guide rail 23 at a constant speed, so the original and recording paper are irradiated uniformly with light from the lamp 25 of the optical system 24, so that a uniform copy picture is obtained.
