Title: Electronic endoscope unit
Inventor: HIGUCHI MITSURU
IPC: H04N7/18
Filed: 1998-02-04
Abstract: PROBLEM TO BE SOLVED: To form a static image with high picture quality by reading out all pixels, stability a clamp processing of black level at the time of selecting still images, and prevent the color reproducibility from deteriorating. SOLUTION: For a static image, all pixels got in one exposure with CCD 12 are readout and those data are output to a mixed circuit 26 via the first memory 23, the second memory 24 and a phase adjustment memory 25 then the mixed pixel signal is formed on it. Thus the static image that is of high picture quality is obtained. On the other hand, for a moving image, the mixed pixel data is output from CCD 12 to faithfully reproduce it. And, based on the control of a micro computer 20, it is switched on an image switching circuit 28 so as to extract the black level part of moving image signal even when the static images are selected. By the feedback on a clamp signal, which formed from the black level voltage, to a clamp circuit, the black level of image signal is reproduced. Thus it is possible to do fine clamp processing without using the past static image signal.

IPC: F01N3/20
Filed: 1990-02-21
Abstract: PURPOSE:To utilize vaporizing fuel from a fuel tank so as to maintain a purifying factor of NOx always at a high value by introducing the vaporizing fuel into an exhaust pipe in the upstream of a lean NOx catalyst when an HC insufficient operation condition is judged. CONSTITUTION:A lean NOx catalyst 6, which is composed of zeolite carried with transition metals or noble metals to deoxidize NOx under presence of HC in the oxidizing atmosphere, is provided in an exhaust system 4 of an internal combustion engine 2. Vaporizing fuel pipes 12, 14, for guiding vaporizing fuel from a fuel tank 8 to a vaporizing fuel absorbing canister 10 and an upstream exhaust pipe 4a of the lean NOx catalyst 6, are provided. Here in an ECU30, a selector valve 16 is selected to a side of the vaporizing fuel pipe 12, when an operation condition of the internal combustion engine 2 detected by an operation condition detecting means is judged in an HC insufficient operation condition, and to a side of the vaporizing fuel pipe 14 when the operation condition is judged not in the HC insufficient operation condition. In this way, a purifying factor of NOx by the lean NOx catalyst 6 can be maintained always in a high value by holding a HC concentration of exhaust gas always in a high value.

Abstract: PROBLEM TO BE SOLVED: To set a proper jackpot winning probability in a development and designing process while maintaining interest of and entertainingness to a player by employing a varying winning device and to predict reliably performance by nail adjustment in a business process. SOLUTION: As the game machine ensures one win while maintaining minimum opening time (0.2 sec. or more) for the plate of a start opening 126, and is practically the same as a winning device that provides only one winning route by closing the plate quickly, a winning probability can be set to the start opening 126 of the game machine relatively easily, and designing a jackpot winning probability and the arrangement of nails 116 becomes easy. Nail adjustment helps forecast performance and eradicates anxiety. As a player is assured of one win, he/she feels no sense of dissatisfaction, and reopening for a prescribed time is implemented as a special service especially after the end of the jackpot game, the interestingness and entertainingness of the game will never be impaired.

IPC: H04N5/92
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To conduct a high density video recording for a long time and to surely correspond the contents of the video signals to added data. SOLUTION: Video signals from plural video cameras 101 are taken in while successively switching them by a multiplexer 103. A frame synthesizing section 1 reduces the taken in video signals to generate reduced video signals and these reduced video signals are assembled into slave screens to generate synthesized video signals. A CPU 3 generates added data relative to the reduced video signals of each slave screen, maintains the correspondence relation between the reduced video signals and the added data and records the synthesized video signals and the added data on the same video cassette tape 7. Thus, the video signals from plural video cameras are recorded with a higher density and a long time recording is made possible.  By using the added data, desired reduced video signals are retrieved from the recorded synthesized video signals and the contents of the retrieved reduced video signals are analyzed.

Title: Synchronizing separator circuit
Inventor: KAMIYA KIYOSHI
IPC: H03K5/08
Filed: 1986-02-25
Abstract: PURPOSE:To simplify a synchronizing separator circuit with easy conversion into an IC by using two MOS-FET and two resistances to produce voltage for both clamping and comparison. CONSTITUTION:When both the 1st and 2nd reference voltage V11 and V12 are set at the same level, the discharging is carried out through an inverse input terminal of a comparator 13 via the 2st resistance even though the 1st n-type MOS-FET12 does not conduct in the period of the luminance signal of a composite video signal. Thus, the voltage V13 is slightly lower than the comparison reference voltage V14 and the synchronizing separation is possible. While the 1st resistance R14 is set less than the 2nd resistance R15 to set the V13 at a level lower than the V14. As a result, the synchronizing separation is possible although the V11 is set equal to the V12. Furthermore, the synchronizing separation is also possible despite the change of the VTH of an element because no dependence is virtually required by changing the substrates of the 1st and 2nd n-type MOS-FET12 and 15 to other potentials like the power supply voltage VSS of a low level, etc.

Abstract: PURPOSE:To reduce the hardware quantity of a PCM charging signal oscillator and to prevent the deterioration in the talking quality by providing the PCM charging signal oscillator in an exchange and inputting a PCM charging signal to a PCM code input terminal of a CODEC circuit. CONSTITUTION:A charging transmission control signal CC is sent in response to the charging traffic unit counted by a controller 14. A PCM charging signal transmission circuit 12 is operated and a PCM charging signal CP is inputted to a PCM code input terminal TRX of a CODEC 112 of a subscriber circuit 11 from the PCM charging signal oscillator 121. The CODEC 112 decodes the PCM charging signal CP and sends the charging signal to a public terminal equipment 2 as an output of the subscriber circuit 11. Since the PCM charging signal oscillator 121 consists of digital circuits, the oscillator 121 is easily subject to large scale integration, and the hardware quantity is saved. Since it is not required to provide an LC filter for suppressing the charging signal to a voice line, the deterioration in the talking quality is not caused.
