Title: Automatic gain control circuit
Inventor: HAGINO HIDEYUKI
IPC: H04N5/52
Filed: 1986-12-26
Abstract: PURPOSE:To set independently the response of automatic gain control AGC between a synchronizing signal and a peak signal by selecting an output of a level comparator means when no peak is detected and selecting an output of the peak detection means when detected by one vertical scanning period so as to obtain a gain control signal. CONSTITUTION:A selected output of a switch 25 is used as a gain control signal through a filter 27 and given to a gain adjustment circuit 21, where the gain is adjusted. In the vertical scanning period next to the vertical scanning period where the discrimination output representing the presence of the peak detection output, the time constant of the filter 27 is decided by charge/discharge of a peak detection circuit 24. Conversely, in the field next to the field where the discrimination output without the peak detection output is obtained, the time constant of the filter 27 depends on charge/discharge of the level comparison circuit 23. Thus, the response is set independently of the synchronizing AGC and the peak AGC.

Title: Electronic machine provided with battery exhaustion indicating function
Inventor: KOSHIISHI TAKAYASU
IPC: H02J7/00
Filed: 1990-11-22
Abstract: PURPOSE:To notice an operator exhaustion of battery reliably by indicating exhaustion of battery until turn OFF of power supply, upon temporary droppage of battery voltage below a predetermined level, and storing the battery voltage drop in an erasable memory means. CONSTITUTION:When battery voltage drop sustains for a predetermined time, a battery exhaustion flag is set in an EEPROM 157. A battery exhaustion lamp at an operation indicating section 156 is then lighted and monitoring of battery voltage resumes. If a power switch 13 is turned OFF at that time, the battery exhaustion lamp is unlighted. When the power switch 13 is turned ON again, the operation resumes. The battery exhaustion flag is now set in the EEPROM 157. In such case, the battery exhaustion lamp is lighted immediately and the monitoring operation is performed similarly. Lighting of the battery exhaustion lamp notices an operator exhaustion of the battery.

Title: Image reconstruction for cone beam data
Inventor: TUY HEANG K
IPC: A61B6/03
Filed: 1999-09-30
Abstract: PROBLEM TO BE SOLVED: To enable simplification of reconstruction processing for fractional cone beam data while allowing enhanced efficiency in the reconstruction processing. SOLUTION: A method of reconstructing an image from fractional cone beam data contains the collection of the partial cone beam data in a two-dimensional array. When the apex advances along a curve, the collected data coincides with the beam of the radiation diverged two-dimensionally from the common apex. The elements of the data present a line integral of an object taken along the beams to be reconstructed. Thereafter, the data are previously weighted 52 and a local coordinate system is defined. The one-dimensional convolution 54 of the data previously weighted is calculated by the local coordinate system along the direction in which the apex contacts the advancing curve. Finally, the data thus convoluted is weighted while being back projected into an image memory 60 three-dimensionally.  In the ideal embodiment, the curve prescribes a spiral path and the kernel for the one-dimensional convolution of the data pre-weighted is a ramp convolver.

Title: Blowby gas reflux device for engine
Inventor: TAKEYAMA MASAKI
IPC: F02M35/10
Filed: 1994-11-25
Abstract: PURPOSE: To prevent adhesion of an oil film to a throttle valve by opening a blowby gas reflux tube to a gas flow passage formed between an inner tube and a downstream side intake inner tube located on its outer side. CONSTITUTION: A gas flow passage 22 is formed circumferentially between an outer periphery of an inner tube 41 and a surge tank inner wall 2a. A blowby gas circulation pipe 5 is opened to a lowermost wall end of a surge tank 2, being faced to the gas flow passage 22. The gas flow passage 22 is separated from a downstream area of a throttle valve 3 where spiral flow is generated, by a cylindrical wall of the inner tube 41, so that blowby gas passing the flow passage 22 is not influenced by the spiral flow. In addition, high speed intake flow directed to a downstream side exists near an opening 221 of the gas flow passage 22, so that the blowby gas in the flow passage 22 is suctioned by the ejector effect of the intake flow, and fed back into the surge tank 2. It is thus possible to prevent contraflow of the blowby gas to the throttle valve 3, and generation of deposite.
