Title: Mos type solid-state image pickup device
Inventor: MURAYAMA TAKASHI
IPC: H04N5/335
Filed: 1987-12-22
Abstract: PURPOSE:To set the light receiving quantity in each divided period in a range, in which photodiodes are not saturated, so as to expand a dynamic range practically by appropriately dividing a light receiving period into plural periods. CONSTITUTION:The electric charge of the signal received by each photodiode during the period corresponding to the phase difference of the vertical scanning signals of 1st and 2nd vertical shift registers 5 and 6 (corresponding to DELTAgamma) is transferred to an output terminal 7 through signal readout lines L1a-Lma and the electric charge of the signal received during the period (T'-DELTAgamma) which is produced by subtracting the period DELTAgamma from the 1-frame readout period T' is transferred to another output terminal 8 through signal readout lines L1b-Lmb. Even if the incident light is strong in such a degree that the photodiodes are saturated, a dynamic range can be expanded when the DELTAgamma is appropriately set. On the other hand, when the incident light is weak, the DELTAgamma is set to zero or an appropriate small value.

IPC: H01M4/06
Filed: 1988-12-23
Abstract: PURPOSE:To have a cylindrical battery with nonaqueous electrolyte, which is highly reliable and wherein internal shortcircuiting is suppressed, by forming a fiber layer consisting of fluoric resin on the surface of a positive electrode plate. CONSTITUTION:A fiber layer 3c consisting of fluoric resin is formed on the surface of positive electrode black mix 3b of a positive electrode plate 3. The fiber layer 3c is in such a condition that polymer particles are coupled with one another to be turned in the form of fibers assuming a three-dimensional meshing structure. Accordingly the positive electrode black mix 3b is prevented from exfoliation, and fine powder attached to the surface is caught faster, and poor insulation is precluded which results from fine powder or crack of the black mix 3b attached to the surface. This provides a battery free from generation of internal shortcircuiting and equipped with a high reliability.

Filed: 1988-12-21
Abstract: PURPOSE:To easily form word lines of conductive layers used as resistances by respectively constituting element isolation regions of insulating films formed on a semiconductor substrate and electrode layers for element isolation formed on the insulating films. CONSTITUTION:On the surface of a semiconductor substrate 1, element isolation electrode layers 30 for dielectric isolation of each memory cell are formed on recessed sections 32 and thin oxide films 33 formed on source diffusing lines 512. Since the layers 30 are put into the substrate 1 between each two adjacent drain areas 21 in X-direction, floating gates 5 can be formed to a plate-like shape.

Title: Parallel operation control circuit
Inventor: KOSEKI KATSUHIKO
IPC: H02M3/00
Filed: 1995-12-13
Abstract: PROBLEM TO BE SOLVED: To decrease the voltage drop of a Schottky barrier diode during parallel operation by connecting a switch element in parallel with the internal abnormality protective diode of a DC-DC converter and providing a circuit for controlling the switching element based on a normal output signal from the DC-DC converter. SOLUTION: When a DC-DC converter 11 is operating normally, a POK signal is outputted with a High level and a transistor TR3 is turned on through a resistor R3 and thereby a TR1 is turned on. Since the TR1 has low ON resistance, a DC voltage 11 is outputted to VOUT without passing through a Schottky barrier diode D1 connected in parallel therewith. The voltage drop VT1 is the product of ON resistance of the TR1 and the output current A11 when the TR1 is used, and since the ON resistance of the TR1 is low, the voltage drop decreases. Consequently, the voltage drop of the Schottky barrier diode during parallel operation of the DC-DC converter can be decreased.

Title: Signal delay circuit
Inventor: HAYASHI OSAMU
IPC: G01S7/523
Filed: 1989-12-15
Abstract: PURPOSE:To form a delay signal having a high S/N ratio by reducing the noise level generated when a delay time is changed over by allowing a current enough to negate the change of a DC current within a delay wire to flow out or flow in with respect to a tap by a current adjusting circuit. CONSTITUTION:A constant current circuit 1 superposes a constant DC current on an input signal to output the superposed signal and a current change-over circuit 3 selects either one of the taps T1 - Tm of a delay wire 2 to allow the output of the constant current circuit 1 to flow in the selected one. A current adjusting circuit B operates the second current change-over circuit B2 so as to select the same tap as the current change-over circuit 3 and the current I2 eaqual to the DC current I1 superposed by the constant current circuit 1 is allowed to flow out of said tap to be allowed to flow in the second constant current circuit B1. Or, the current equal to the DC current superposed by the constant current circuit 1 is allowed to flow in all of taps other than the tap selected by the current change-over circuit 3 in the current change-over circuit B2. As a result, since no change of the DC current is generated in the delay wire 2, no noise is generated.
