Title: Language processor
Inventor: TAKAYAMA NAOHISA
IPC: G06F17/22
Filed: 1989-05-17
Abstract: PURPOSE:To improve the language processing speed of the processor by automatically producing the reading of a designated unknown word after the unknown word is designated. CONSTITUTION:A reading table 3 stores readings of characters. A reading generating means 4 generates reading candidates for an unknown word designated from an unknown word designating means 2 by retrieving readings of each character of the unknown word from the table 3 and correlating the retrieved readings to each character of the unknown word. A reading deciding means 5 decides the reading of the unknown word from the candidates obtained by the means 4 and the decided reading is registered in a word dictionary 1. Therefore, it becomes unnecessary to the user of this language processor to newly input the reading of an unknown word and the display of an unknown word, registration of the reading, and additional information of the unknown word are operated easily. Thus the language processing speed is improved.

Title: Optical transmission system
Inventor: TAKEYARI RIYOUJI
IPC: H04B10/255
Filed: 1992-05-15
Abstract: PURPOSE:To make the effect of a self-phase modulation effect(SPM) constant even when the interval of repeaters is not uniform by selecting output power of an optical transmitter and the optical repeater to be a ratio of a distance of optical fibers connecting to the output of the optical transmitter and the optical repeater. CONSTITUTION:The output power of an optical transmitter 1 and an optical repeater 2 is selected to be a ratio of distance of optical fibers 3 connecting to the optical transmitter 1 and the optical repeater 2. Or let a distance of the optical fibers 3 connecting to the optical transmitter 1 and the optical repeater 2 be l, the nonlinear refractive index be (n), an effective mode field area be A and an attenuation factor be alpha, the ratio of the output power of the optical transmitter 1 and the optical repeater 2 is selected to be (lalphaA)/n. Since the generated quantity of the SPM caused in each relay block is nearly proportional to the relay distance, the total sum of the effect of the SPM as the entire transmission system is almost equal even when the distance configuration of relay blocks is changed. Furthermore, since the optical output power is higher than the case with compensation of a loss of the optical fibers 3 based on the setting method of the optical output power, deterioration in the S/N is not caused.

Title: Measuring method for humidity in drier
Inventor: OKA AKIHIKO
IPC: G01N27/02
Filed: 1980-09-05
Abstract: PURPOSE:To obtain in accurate measured value by constituting the device so that its operation for measuring humidity is conducted in a fixed phasic relation with the action of means for discharging intermittently a substance to be dried and in the state of stoppage of the substance constantly. CONSTITUTION:Based on a driving signal from a control part 16, a rotary valve 3 operates and a humidity meter 9 conducts measurement simultaneously. When the measurement of humidity is conducted by the humidity meter 9, a data signal is converted into humidity content via an operating part 18 based on a data send signal. By the action of a timer 17, the driving signal is transmitted during a period t1 in a cycle T1, while a measurement signal is transmitted in a cycle T2, and thereby the measurement of humidity is started and ended in a period t2. The measurement signal is given in synchronization with the driving signal and transmitted in phasic relations wherein the former is delayed constantly in a phase difference Td. The phase difference Td is set so that the measurement of humidity by the himidity meter 9 is conducted while the movement of the substance to be dried is stopped. Since the measurement of humidity is conducted constantly in the state of stoppage of the substance to be dried by such a constitution, an accurate measured value can be obtained.

Title: Method and device for controlling output of electric consumption body
Inventor: SCHULZ DETLEF
IPC: H02M5/257
Filed: 1998-05-06
Abstract: PROBLEM TO BE SOLVED: To suppress harmonics from being generated by initially controlling a second circuit in parallel with a first circuit that is connected to a consumption body in series and succeeding to the current of a second circuit, immediately after a specific threshold current through the consumption body reaches one of either threshold voltages of a first circuit. SOLUTION: A trigger signal that is generated by a basic control part GS starts an inclination control part RS, and a transistor TD is switched on by a gradually controlled inclination according to a generated inclination. Therefore, a leading edge accompanies a desired trigger time and delay time until a preset maximum current is achieved by a load RL. Basic controls are connected in parallel, to each other. The one that is connected in series with the load is a triac TC, and the other that is connected in parallel is a power transistor TD. They are successively connected to the load RL in a proper order in temrs of time, and the leading edge gives priority to the gentle trigger time for the circuit.

Title: Brushless motor
Inventor: KAWASHIMA KOTOJI
IPC: H02K29/12
Filed: 1985-06-06
Abstract: PURPOSE:To obtain a pulse signal of high level from a detecting coil by applying a leakage magnetic flux from a drive magnet to strengthen the magnetic flux of a magnet from generating a pulse signal. CONSTITUTION:Since a magnetic flux varies when the variable portion of the pole of a magnet 20 for generating a pulse signal passes the vicinity of a detecting coil 21, the coil 21 detects it and outputs a pulse signal in response to the sequence of the poles. Since the variable portions of the N- and S-poles of a drive magnet 19 and the variable portion of the pole of the magnet 20 are aligned, the coil 21 adds the leakage magnetic flux from the magnet 19 to raise the level of the pulse signal. Further, since the coil 21 is disposed to direct its winding axis toward the magnet 20, a counterelectromotive force is not generated to eliminate a repelling.
