Title: Photodiode
Inventor: OGAWA TAKESHI
IPC: H01L31/10
Filed: 1988-04-07
Abstract: PURPOSE:To obtain the photocoupling between a photodiode and a light emitting device or an optical fiber easily by forming light shielding films radially on an insulating film except the light detecting surface of the photodiode, radially with the light detecting surface as the center. CONSTITUTION:A different conductivity type region 6 is formed in a part of a semiconductor substrate 1 by impurity diffusion to form a p-n junction 10. The region in which the p-n junction is provided is used as a light receiving surface 2. A transmitting insulating film 3 is formed on the semiconductor substrate surface including the light receiving surface 2 and an annular hole is formed in the part of the insulating film 3 along the circumference of the light receiving surface 2 to form an electrode 4. After A is evaporated over the whole surface of the insulating film 3 outside the electrode 4, the Al film is removed radially with the light receiving surface 2 as the center to form light shielding films 5. As the parts which have photosensitivity are provided at any parts of the surface of the photodiode, a photocurrent can be induced by light emitted from a light emitting device or the like. With this constitution, the photocoupling of the emitted light from an optical fiber or the like can be obtained easily.

Title: Method for operating press bending apparatus for beinding ofglass plate
Inventor: DEIITAA FUNKU
IPC: C03B23/035
Filed: 1995-04-12
Abstract: A method for operating a glass pane bending press, in automatic vehicle glazing mfr., involves: (a) lowering a bent glass pane, held by a vacuum holder below the male mould, by downward motion of the upper press crossbeam onto a shuttle ring held at a constant level above the female mould; (b) controlling the downward motion according to a velocity curve having an initial acceleration portion, a max. velocity section and a subsequent deceleration portion for gently laying the pane on the shuttle ring; and (c) designing the curve such that the first diversion of the curve progresses without singularities. The reduced pressure of the vacuum holder matches the pane wt. and the deceleration of the downward motion is adapted to this reduced pressure so that the vacuum holding force is always greater than the counter-force resulting from deceleration and such that the pane is not released from the male mould during deceleration. After redn. or switch-off of the reduced pressure, the pane is laid on the shuttle ring. <IMAGE>

Title: Formation of optical waveguide
Inventor: TO YOICHI
IPC: G02B6/12
Filed: 1990-04-03
Abstract: PURPOSE:To obtain stable characteristics by injecting ions of oxygen into an SiO film selectively and forming a noninjection area, surrounded with an area which is reduced in refractive index, as a waveguide. CONSTITUTION:The oxygen 14 is ion-injected into the SiO film 12 to form the refractive index of the SiO film 12, thus forming the optical waveguide 16. Namely, the area 15 where the oxygen 14 is ion-injected selectively into the SiO film 12 is reduced in refractive index and the area where the injection is not performed is relatively high in refractive index, so the noninjection area is usable as the optical waveguide 16. Consequently, the optical waveguide can be formed of a material and impurities which are used in a normal semiconductor process and the semiconductor which is stable is realized.

Title: Differential amplifier
Inventor: MASUKO KOUICHIROU
IPC: G11C11/409
Filed: 1980-06-26
Abstract: PURPOSE:To sufficiently ensure a write of 0V into a memory cell to increase the working margin of a dynamic RAM, by using the memory cell recharge pulse of the dynamic RAM for the discharge of a differential amplifier. CONSTITUTION:A transistor TR is shifted to a state of conduction by a clock phi to discharge the potential of the source phi3. On the other hand, a TR12 is shifted to a state of conduction by a control signal phi0' to discharge the potential of the source phi3. In this case, the potential of phi3 may possibly float up with a rise of the recharge pulse. To prevent this phenomenon, a TR13 is shifted to a state of conduction by a pulse phi4 to discharge the potential of phi3. As a result, the potential of phi3 never floats up but keeps 0V. Thus 0V can be written enough into a memory cell.
