Title: Piezoelectric oscillator
Inventor: AKAGAWA HIROAKI
IPC: G06F1/04
Filed: 1990-03-30
Abstract: PURPOSE:To keep stable oscillation even when ambient temperature changes by varying a power supply current supplied to an inverter in response to the ambient temperature. CONSTITUTION:When ambient temperature rises, a voltage caused at a connecting point between a resistor R6 and a temperature detection circuit 7 rises. The voltage is given to an inverting input terminal of an operational amplifier 6-1, in which the voltage is amplified and fed to a base of a transistor(TR) Q7 as a control voltage. Thus, the applied voltage to a C-MOS inverter 1 rises and a supplied power supply current ICC is increased and the negative resistance rho of the circuit is increased. As a result, a change in the decreasing direction of the negative resistance rho as the ambient temperature is corrected. Thus, the negative resistance rho is large and kept constant and even when the ambient temperature rises, stable oscillation is kept.

Title: Fiber for optical communication
Inventor: SASAKI YUTAKA
IPC: G02B6/02
Filed: 1980-06-24
Abstract: PURPOSE:When optical fiber is produced through the MCVD process, the clad part is made from P2O5-F-GeO2-SiO2 glass to give long fibers with very low optical loss in the wave-length zone of longer than 1.3mum. CONSTITUTION:The glass composition of the clad part is made P2O5-F-GeO2-SiO2. As an F-source, is used SiF4, CF4 or SF6. P2O5 mainly lowers the deposition temperature and F reduces the refrative index. GeO2 compensates excessive reduction in refractive index caused by F. Thus, the refractive index of the clad is readily adjusted to 1.458, equal to that of SiO2, in spite of the deposition point of about 1,400 deg.C, such a small amount of P2O5 as the loss in infrared rays characteristically caused by P2O5 can be ignored, and a small amount of SF6 that can stably control the flow rate. Further, since the deposition temperature is low, long fibers are obtained without deformation and the absorption loss intrinsic to the dopant is not caused.

Abstract: PURPOSE: To eliminate distance measurement errors and enable the magnified images for distance measurement to be viewed always within the same visual field by so constructing the finder that a semi-transparent mirror is diagonally provided immediate behind the distance measuring part of the focal plate and the main optical axis luminous flux from the photographing lens is bisected to the luminous fluxes for distance measurement and is thereby utilized.  
     CONSTITUTION: A semi-transparent mirror 4 is diagonally provided to the central part of the optical axis of a condenser lens 3 and the main optical axis luminous flux coming from the photographing lens is bisected to luminous fluxes for distance measurement. Further, these are reflected by the first reflecting surface 10 of the small prism 9 for distance measurement disposed behind the condenser lens and the roof part 11 disposed above thereof, thence they arrive at the main eyepiece lens 7 through the eyepiece lens 12 for distance measurement. With this constitution, the luminous fluxes for distance measurement become perfectly erecting images on the upper, lower and right and left. The light distant length from the distant measuring part 2 up to the eyepiece lens 12 for distance measurement is shorter as compared to the main optical axis light distant length and the rate of magnification about 3 times that of the main axis plane is obtained. Since the magnified images for distance measurement appear at all times within the same visual field, focusing is easy.
