Abstract: PURPOSE:To perform both the affine transformation and the raster scan at a high speed through the same circuit by defining the sets of integers indicating a digital picture as the independent vatiables for execution of the raster scan and at the same time producing the sets of addresses corresponding to said sets of integers. CONSTITUTION:An address generating circuit repeats the actions to extract once selectively the contents of registers 20 and 21 holding the present (x) and (y) addresses synchronously with the raster scan until one of independent variables X and Y is initialized. At the same time, the address generating circuit extracts once selectively the contents of registers 22 and 23 holding the initial address values in a fixed order after one of both variables X and Y is initialized. Then the actions to read out once selectively one of (a) and (b) as well as (c) and (d) stored in a storage means are repeated synchronously with the raster scan until the X or Y is initialized. Thus it is possible to perform at a high speed the calculation of picture element addresses based on the affine transformation and the raster scan through the same circuit.

IPC: B41J2/085
Filed: 1980-05-02
Abstract: PURPOSE:To prevent stain of a picture and blanking by impressing voltage so as to cancel a voltage induced by electrostatic induction from an adjacent charging electrode in the captioned device of a charge control type. CONSTITUTION:On an input terminal 11a is impressed voltage Vn+1 to be charged on ink droplets at the charging electrode 4 thereof, while on terminals 11b and 11c are impressed voltages Vn and Vn+2 to be charged on ink droplets jetted from nozzles positioned adjacently on both sides thereof, respectively. Accordingly, the charging electrode 4 is not influenced by the voltages on both adjacent sides since a voltage to cancel the electrostatic induction is impressed on the charging electrode 4 by the voltages impressed on charging electrodes on both adjacent sides. In addition, voltage induced in the adjacent charging electrodes is fixed since a signal given to the input terminal is a binary signal, while the adjustment of unevenness can be conducted by means of variable resistors 13 and 14.

Title: Voltage controlled oscillator
Inventor: IKEMOTO NAOMICHI
IPC: H03K3/354
Filed: 1987-03-13
Abstract: PURPOSE:To reduce influence on an oscillation frequency due to the fluctuation of a power source voltage and temperature, by connecting an inverter of full-return equivalent to two inverters which constitute a comparator limiting the upper and lower limits of a capacitor, and charging and discharging the capacitor with a constant current proportional to the difference of the outputs. CONSTITUTION:A constant current circuit 2 is provided with a reference voltage generation circuit 1 having the inverters 7 and 8 whose threshold voltages are VH and VL. The inverters 7 and 8 of full-return are the same as the inverters 14 and 15 of a charging voltage detection circuit 5. A voltage VDD is biased to the voltage divided by the resistance of the output of a voltage follower 10, and is impressed on a negative feedback differential amplifier 11, and the output of a voltage follower 9 is impressed on the inverted input of the amplifier 11 via a resistor R2, and the output e0 is impressed on the non-inverted input of an operational amplifier 12. The threshold values VH and VL can be obtained at the outputs of the inverters 7 and 8, respectively. At this time, assuming as R2=R3 and R4=R5, the output current of the circuit 2 goes to I=R4/{R1R2(VH-VL)} and the oscillation frequency (f) goes to f=R4/(CR1R2). Thus, since the difference voltage (VH-VL) of the threshold values is used as a reference voltage, it is possible to reduce the fluctuation of the power source voltage and the temperature in the oscillation frequency (f).

Title: Wavelength converter
IPC: H01S5/0625
Filed: 1992-03-16
Abstract: PURPOSE:To quickly convert a light pulse train of one wavelength into a light pulse train of the other wavelength, by introducing an oscillation light of a variable wavelength laser part and an external input light into an optically nonlinear amplifier having a structure wherein optical amplifiers and saturable absorbers are alternately arranged in a semiconductor optical waveguide. CONSTITUTION:A waveguide constituted of an amplifier 1G and a saturable absorber 1A is formed on a semiconductor substrate 101. A current flows in the forward direction through the amplifier 1Gk, which almost lineally amplifies an optical signal. The absortion coefficient of the saturable absorber 1Ak is small for large light intensity, and nonlinear I/O characteristics are exhibited. Since sufficient nonlineality can not be obtained by the general amplifier 1Gk and saturable absorber 1Ak, these are arranged in the multistage. By making the final stage amplifier 1G(n+1) long, amplification saturation is caused, so that excellent threshold characteristics can be obtained. The waveform of an inputted signal pulse is regenerated in vertue of high speed response of the elements, and the wavelength is converted to be outputted. That is, the wavelength conversion of a light pulse train is enabled.

Filed: 1995-03-17
Abstract: PURPOSE: To early detect a fault in order to improve the reliability of a mobile communication system by collecting the call processing alarms between the mobile and base stations at a monitor station and retrieving these collected alarms to compare them with the threshold for decision of the fault occurrence. CONSTITUTION: The call processing alarms which are generated in the case of interrupting the squelch due to reproduction of the reception level caused between a mobile station 1 and a base station 2 are collected via an exchange 3 and stored in a storage 15 of a data management center 13 of a monitor station 4. Then a fault decision part 14 retrieves the part 15 and compares the number of processing alarms collected in a fixed with the threshold. When the number of these collected alarms is larger than the threshold, the part 14 decides a fault occurred in an area. Therefore, the fault is detected before the operation is completely stopped. Then other information of the fault occurrence is given to a mobile terminal equipment 1 and at the same time the switching control is applied to a transmitter-receiver 6 of the station 2.  Thus it is possible to improve the reliability of a mobile communication system which can early and automatically discriminating a fault without executing manual statistic processing.

Title: Pressure sensor of optical fiber
Inventor: ICHIMURA KIYOSHI
IPC: G01L1/24
Filed: 1987-03-16
Abstract: PURPOSE:To dispense with complicated machining of rigid-body plates of a sensor and to facilitate assembling and fitting of the rigid-body plates, by a method wherein an optical fiber bundle formed by braiding a plurality of optical fibers is used as a pressure detecting element. CONSTITUTION:A braided bundle 1 of optical fibers is in a uniform state when it is not pressed. When a pressure is applied to the optical fiber bundle 1, only a part thereof to which the pressure is applied is deformed, and therefore a loss of light in optical fibers 2 in this part increases. While the loss of light increases with an increase in a pressing force, it tends to be different according to braiding. Accordingly, pressure sensors having different sensitivities can be furnished by adjusting the number of times of braiding. In other words, the sensor requiring a large sensitivity can be furnished by increasing the number of braidings, while the sensor not requiring the same can be furnished by lessening said number. Since a pressure detecting element is constructed of the braided optical fibers in this way, a pressure member having a specific indented surface is dispensed with, and the pressure sensor can be constructed only by holding the pressure detecting element between flat rigid-body plates 5.

Title: Control device and control method for automatic transmission
Inventor: MINOWA TOSHIMICHI
IPC: F16H61/08
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To provide a transmission characteristic both good and repeatable by computing a pressure adjustment instruction value for keeping the preset value of hydraulic pressure supplied to a frictional engagement device during the initial period of a recognized inertia phase. SOLUTION: In the acceleration signal calculation means 32 of a controller 31, a differential value or a difference between a transmission output shaft speed No for the current operational period and a transmission output shaft speed No for the previous operational period is divided by the operational period, thereby calculating acceleration along the forward and backward direction of a vehicle. This acceleration along the forward and backward direction of the vehicle has a relationship of similarity with the torque of the transmission output shaft and, therefore, torque phase and an inertia phase at the time of a gear change operation can be found from the acceleration along the forward and backward direction of the vehicle. In other words. a gear change state can be recognized.  Also, a torque fluctuation over the first half of the inertia phase is restrained on a feed-forward basis, thereby improving the robust function of subsequent feedback control, and providing a good and repeatable transmission characteristic.
