Title: Solid state image sensing device
Inventor: UEHIRA KAZUO
IPC: H04N5/341
Filed: 1988-10-25
Abstract: PURPOSE:To prevent transfer efficiency from being lowered by applying to a first output gate electrode a voltage higher than that of a second output gate electrode. CONSTITUTION:There are independently connected to a voltage application terminals 14, 15 a first output gate electrode 2 comprising a first layer polycrystalline silicon film adjoining to a floating diffusion layer 1 provided on a silicon semiconductor substrate and a second output gate electrode 3 comprising a second layer polycrystalline silicon adjoining to said electrode 2. In such a construction, provided a higher voltage is applied to the electrode 2 than the third electrode 3, all electric charges existent under a transfer electrode flow into the floating diffusion layer through an output gate voltage to eliminate any remaining charges not transferred under the output gate electrode. Thus, those electric charges can securely be transferred to the diffusion layer 1 to prevent any lowering of transfer efficiency.

Title: Degenerated operation method for redundancy system
Inventor: FUJISHIMA YASUTAKA
IPC: G05B9/03
Filed: 1986-11-14
Abstract: PURPOSE:To maintain the function, performance and reliability of a redundancy system by estimating the rise of temperature of a control device and resetting the operation of the system to a degenerated operation mode or a normal mode based on the estimated temperature rise. CONSTITUTION:The analog signals of a temperature sensor 7 attached at the outside of a housing are periodically fetched by a process signal input/output part 331 in a control device 13. The peripheral temperature of the sensor 7 and this temperature rise rate are calculated by a controller part 332. Then the rise transition of the peripheral temperature of the device 13, i.e., the peripheral temperature of the device 13 to be set after a fixed time is estimated by knowing previously the information on the calculation of the part 332 as well as the information on the heat value generated within the housing, the heat transmission delay time to the housing, etc. The part 332 cuts off the power supply line of each subsystem by digital output signals 81 and 82 received from an input/output part in its own subsystem in response to the estimated temperature in case the temperature is liable to rise within the housing and this temperature rise may possible affect adversely the device 13. While the power is supplied to the subsystem when the estimated temperature T rises up to a normal level at the periphery of the device 13 and the operation is reset to a normal redundancy system.

Abstract: PROBLEM TO BE SOLVED: To provide a three-dimensional shape measuring instrument which has a simple constitution and yet can measure a wide extent of area at once and the resolution of which can be improved in the distance and the direction. SOLUTION: A laser beam emitted from a laser device 1 is inputted to a modulator 3, and the modulator 3 modulates the intensity of the beam 2 by using the output signal of an oscillator 4 for modulating laser beam intensity. An x-y two-dimensional scanner 10 projects the modulated laser beam upon an object 13 to be measured by performing scanning with the modulated laser beam in arbitrary elevation and azimuth directions. The reflected laser beam from the object 13 is made incident to a photodetector 22. The photodetector 22 is modulated in intensity with a frequency which is slightly different from that used for modulating the intensity of the laser beam 2 and outputs a beaten- down low-frequency signal as a light receiving signal 24. A phase difference detecting circuit 19 output a phase difference signal 25 from the light receiving signal 24 and a reference signal 18.  A user interface 6 finds the three- dimensional shape of the object 13 from the phase difference signal 25 and positional information of the scanner 10, and displays the found shape on a display device 26.

Abstract: PURPOSE:To parallel incident light and exit light and to facilitate optical axis adjustment as well as to diminish the space in the case of incorporation into a device and to allow miniaturization by forming an incident surface and exit surface consisting of point symmetrical mirror surfaces on both end faces in the major axis direction of a crystal having a nonlinear optical effect.

The incident laser beam on the incident surface 11c at an angle theta arrives at the incident surface 11d on the opposite side through the center of the crystal and is totally reflected by this surface. The reflected light repeats reflection on the lane 11b and the plane 11a and is again returned to the incident surface 11c. The laser beam returned to the incident surface 11c is again reflected there and is resonated in the process of tracing the same optical path in the crystal, by which the energy density is increased. This energy density is converted to a second harmonic wave which is emitted in the direction parallel with the incident light.
