Title: Drive for automatic feedwater pump in reservoir
Inventor: SHIMIZU YOSHIYUKI
IPC: F04B49/06
Filed: 1988-07-27
Abstract: PURPOSE:To prevent any overload from being imposed on a motor by varying frequency with a variable speed inverter, bringing pumping power into full play, and after being reached to a rated current, keeping the frequency constant. CONSTITUTION:In a water-distribution system, when a demand of water is increased, there is produced a difference between a pressure sensor 8 and a pressure setter 10, and on the basis of this difference, frequency is converted by a variable speed inverter 11 whereby rotational frequency of an induction motor M goes up. When it comes to a rated current value, however, the voltage and frequency pattern of the variable speed inverter 11 should be set in advance so as to prevent rotation of the induction motor M from going up to more than that. When the demand of water is decreased and pressure is approximated to the setting value, the rotation of the induction motor M is lowered, coming into a state of being on standby.

Title: Vertical writing/lateral writing decision method of character area
Inventor: AMAMOTO NAOHIRO
IPC: G06K9/20
Filed: 1991-07-26
Abstract: PURPOSE:To precisely perform a character string extraction and a character recognition by performing the decision of a vertical writing/lateral writing every character area within a document picture. CONSTITUTION:A character discrimination processing 2 discriminates which a single character string within a binarized character picture or any one of character areas other than it is. In a longest white run distribution extraction processing 3, the longest white run distribution is extracted by scanning each rectangular internal part decided as a character area in vertical and lateral directions. In a white run width histogram preparation processing 4, the histograms of the white run widths of the lateral and vertical directions are prepared from the change of the longest white run distribution. A white run width detection processing 5 detects a continuous white run width giving a maximum value in the histogram of the white run width or the widths of the interlinear and character spacing every rectangular internal part. Generally, since the interlinear is wider than the character spacing, the writing direction of characters can be known by comparing these two values in a vertical writing/ lateral writing decision processing 6.

Title: Direct modulation psk transmission system and automatic frequency control method and demodulation and phase noise suppression method in the system
Inventor: NAITO TAKAO
IPC: H04B10/516
Filed: 1990-07-18
Abstract: PURPOSE:To eliminate the need for the circuit to recover a carrier and to simplify the device constitution by controlling a frequency of a local radiation light so that the frequency of a line spectrum signal is made constant. CONSTITUTION:A narrow band BPF 25 passes a line spectrum whose frequency is fIF-B or fIF+B among signals from an optical detection circuit 8, where B is a bit rate. A negative feedback circuit 29 applies voltage-current conversion to an output signal of an LPF 28 to give a negative feedback to a local oscillation LD 24 so that the frequency of an intermediate frequency signal is constant. When the frequency of the line spectrum signal inputted to a mixer 27 and the frequency of the signal from an oscillator 26 are completely coincident, a DC output with a level proportional to the product of the signal amplitudes is obtained from the mixer 27. When the frequency of the line spectrum signal is fluctuated, since a level of the DC output is also changed, the feedback 29 is applied to cancel the change, then the frequency of the line spectrum signal is kept constant.

IPC: H03B5/12
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To suppress the current change of an oscillation circuit that is caused by the noises and to reduce the phase noise levels of oscillation signals even against the low frequency to secure a stable oscillation operation by connecting a capacitor to a constant current source to ground it in terms of AC and adding an AC impedance to the impedance of the constant current source. SOLUTION: A capacitor 21 is connected to the base of a transistor 16 of a constant current source 11 via a terminal 19 and then grounded in terms of AC. Thereby, the AC impedance set at the terminal 19 can be significantly reduced compared with the case where the capacitor 21 is not connected to the terminal 19 since 1/ωCO (ω=2πfi, fi: current frequency) of capacity CO set by the capacitor 21 is added to the impedance of a resistor 13 of resistance value R1 of the source 11. Thus, it's possible to eliminate the thermal noises, etc., caused by the resistor 13 of the source 11, to reduce the change of base bias voltage of a transistor 9 of a current source 8 of an oscillation circuit 1 and to reduce the phase noise levels of oscillation signals.

Title: Medium for light transmission
Inventor: ANDO MIGIWA
IPC: G01N25/20
Filed: 1989-07-20
Abstract: PURPOSE:To attain the selection of a medium for light transmission having such a high temp. sensitivity so as to generate a large refractive index gradient with a small temp. change by calculating the value of the coefft. of thermal expansion/(specific heat x density x thermal conductivity) of the medium. CONSTITUTION:A laminar flow state is attained when the medium flowing in a tubular body 1 is heated from the wall part. The density of the medium in the peripheral part is then made lower than the density in the central part and the distribution of the refractive indices symmetrical with a central axis is generated. The incident light on the medium in the tube is bent inward like a line (a) and the absorption and scattering on the wall surface are decreased. The quantity of the received light is thereby increased and the state like a line (b) is attained in the case of cooling. The large refractive index gradient is obtd. with a small heat quantity if the value of alpha/(CP.lambda.rho) is so determined so to attain >=5 where the specific heat of the medium is designated as CP(cal/ g. deg.C), the thermal conductivity as lambda(cal/cm.sec. deg.C), the coefft. of thermal expansion as alpha(1/ deg.C), and the density as rho(g/cm<2>). The measurement of the density., etc., is thus executed with the high sensitivity.
