Title: Charge transfer device
Inventor: KURIYAMA TOSHIHIRO
IPC: H01L29/762
Filed: 1989-11-20
Abstract: PURPOSE:To increase the speed of charge transfer at low voltage by making superposition with the storage-section electrode of a required barrier electrode forming a CCD element larger than that of another barrier electrode. CONSTITUTION:CCD elements constituting a CCD shift register are shaped by the first layer polycrystalline silicon 5 of charge storage electrodes and the second layer polycrystalline silicon 6 of barrier electrodes. Superposition with the silicon 5 of the silicon 6 on the downstream side in the direction of flow of currents driven by driving pulses having the same phase as the silicon 5 is made larger than that with other electrodes driven by driving pulses having different phase. Consequently, a potential pocket generated between the electrodes is generated only between different-phase electrodes, and the potential pocket is removed only by pulse width and the dispersion of internal potential difference due to process variation is inhibited. Accordingly, charges can be transferred at high speed by drive at low voltage.

Title: Optical i/o device of semiconductor
Inventor: NAKANO YOSHINORI
IPC: H01L29/74
Filed: 1989-11-20
Abstract: PURPOSE:To simplify and miniaturize a device by connecting both ends of a photo detector having a PN junction with different power supplies, via a load resistance element of an optical thyristor, with the same polarity as the current of the optical thyristor, in the forward direction. CONSTITUTION:From a power supply E1, a current Ic is made to flow in an optical thyristor S in the forward direction via a resistance element R. At the same time, a part of the output light L'' from the thyristor S enters a photo detecting element D having a PN junction, and a small current I1 from a power supply E2 is made to flow in an element R in the same direction. As a result, the voltage drop of the element R is small, and therefore the state that the thyristor S radiates a light L' is maintained. In this state, when a pulse type light is input to an element D, it makes a larger current It' as compared with the current I1 flow in the element R, and the voltage drop of the element R increases. Hence the voltage between both ends of the thyristor S becomes lower than the holding voltage of the thyristor S, so that it turns OFF and the output of light L' is interrupted.

IPC: G03B13/36
Filed: 1987-11-30
Abstract: PURPOSE:To perform automatic focusing in which malfunctions are few and responsiveness is excellent by constituting a device so that automatic detection action is restarted again at the time of detecting a direction of slipping out of a movement inhibition area with a focus detecting action based on a focus detection means. CONSTITUTION:In an automatic focusing device, the moving area of a 4th lens group 1d of a zoom lens 1 corresponding to the object distance out of a range from the closest to infinity in each maximum focal distance as for each focal distance range is set as an inhibition area.

Such a state is continued, thereafter, until the focus detection means 5 can detect a proper direction where the 4th lens group 1d should move and the lens driving control means 6 is switched to the control of driving the lens based on the focus detection means 5 at the time detecting the direction.

Title: Data transmitter
Inventor: FUNATSU TETSUYA
IPC: H04L12/40
Filed: 1989-11-24
Abstract: PURPOSE:To attain transmission reception of a data requiring urgent transmission with priority without the need of considerable hardware modification by interrupting the transmission processing of usual data and applying reception processing when a usual data and an emergent data are sent to a transmission line and the data are collided with each other and superimposed. CONSTITUTION:When a data requiring urgent transmission is included in a data sent from a controller 24, a transmitter 2 sends an emergent transmission signal. A usual (cyclic) transmission data is given to a transmission line 3 from other node and the data signal collides with the emergent transmission signal and superimposed thereon. Since the resulting signal level differs from the usual signal level, a collision detection means 22 detects it that the reception signal is a collision data by using the level as an index. Each transmitter 2 during usual transmission stops the transmission through the detect of data collision, opens the transmission line 3, and the data is sent to the transmission line and the urgent data is received by each transmitter. Thus, the transmission reception of a data requiring urgent transmission reception is implemented with priority without remarkable modification of the transmitter or the like.
