Title: Switching circuit, converter using the same and power factor improved power source
Inventor: NOTOHARA YASUO
IPC: H02M3/155
Filed: 1991-06-19
Abstract: PURPOSE:To switch a zero current without depending upon a frequency of a resonance circuit by providing the resonance circuit and an auxiliary switching element at a main switching element and operating a resonance operation by the auxiliary switching element. CONSTITUTION:When a transistor 4 of a main switching element is turned ON, charge stored in a resonance capacitor 5 is reversely charged in the capacitor 5, and a resonance operation is interrupted in a state that the charge is maintained. Then, when the transistor 4 is tuned OFF, a transistor 10 of an auxiliary switching element is previously tuned ON. A series circuit is reversely biased by the reversely charged capacitor 5, and the resonance operation is restarted. Since no current flows to the transistor 4 while a resonance current flows to a diode 11, a loss of a zero current switching can be reduced by turning OFF the transistor 4 during this period. A switching frequency can be continuously varied without depending upon the frequency of a resonance circuit by the operation of the transistor 10.

Title: Edtv reinforcing signal interference reduction system
Inventor: SUZUKI NORIHIRO
IPC: H04N5/21
Filed: 1994-06-29
Abstract: PURPOSE:To reduce interference to an existing receiver due to a reinforcement signal multiplexed on a main image part or a non-image part in the letter box system wide EDTV system. CONSTITUTION:A sender side measures an absolute value of an input signal and a low pass filter(LPF) 23 filters the input signal. The gain of the input signal is controlled with the output of the LPF. At the receiver side, the absolute value of the input signal is measured at first similarly to the transmitter side and an LPF 28 filters the signal. The gain control of the inverse characteristics to that of the transmitter side is implemented by the output of the LPF and an original signal is reproduced. Since amplitude companding is conducted by using a linear element, no distortion is caused. Furthermore, since a gain coefficient is multiplied with the signal itself, the amplitude is compressed both for low and high frequencies. Thus, the interference to an existing receiver is reduced.

Filed: 1995-06-15
Abstract: PURPOSE: To accurately detect the end of toner, without using a sensor by comparing toner consumption with the initial toner capacity of a storage means and detecting the end of the toner, when the toner consumption exceeds the initial toner capacity. CONSTITUTION: A CPU 51 allows an exposure device controller 54 to output a lighting instruction signal for controlling the lighting time of a light source in every dot to an exposure device, based on a multi-level image pattern extended in a RAM 53. Thus, the exposure device controls a pulse width, that is, the lighting time of the light source, based on the multi-level image pattern. Then, the pulse width of the light instruction signal in each dot is integrated. After that, an integrated time is converted into the toner consumption from the correspondence relation of the time of the pulse width and the toner consumption. In other words, the toner consumption is calculated. Further, the initial toner capacity previously set in a ROM 52 is compared with the toner consumption. In this comparison, when the toner consumption exceeds the initial toner capacity, the end of the toner is detected to inform an operator of it.

Title: Optical detector for fluid sample
Inventor: NOGAMI TARO
IPC: G01J1/42
Filed: 1994-06-30
Abstract: PURPOSE:To reduce the error of a flow injection measuring apparatus by providing a slit and means for condensing the light scattering through the slit between a spectrometer and a flow cell disposed on an optical path thereby eliminating the trouble of the optical path on the inside and outside of the cell. CONSTITUTION:Light emitted from a deuterium lamp 3 is condensed by a condenser mirror 4 and enters through a quartz window 5 into a spectrometer room 2 where the light passes through a cut filter 6 and enters into a spectrometer through an incident slit 7. The light is scattered, for each wavelength thereof, through a concave diffraction grating 8 and a light of one wavelength enters through an outlet slit 9 into a detection room 40. The monochromatic light is condensed again through a recondensation mirror 10 and advances toward a flow cell 12 but it is partially directed toward an object side detector 14 through a beam splitter 11 inserted into the way of the optical path. The luminous flux advancing toward the flow cell 12 enters into a sample side detector 13 while being condensed. Since the fluctuation in the quantity of incident light to the detectors 13, 14 matches well, the fluctuation can be corrected accurately based on the output ratio thereof.
