Title: Boiler reheated steam temperature control system
Inventor: OKANO MASATO
IPC: F22G5/12
Filed: 1977-09-21
Abstract: PURPOSE:  To efficiently control the reheated steam temperature of boiler, by injection into the steam and by correcting through a reheated steam temperature deviation signal the quantity of the injection determined depending on the load on the boiler.  
     CONSTITUTION: In controlling the injection of water ( RH spray ) into a reheated steam temperature unit, the quantity of the RH spray necessary in connection with the load on the boiler is determined by a function generator 16 from a boiler load signal 1. The proportional integration of the difference between a reheated steam temperature signal 2 and a setpoint signal 5 is performed by a PI calculator, and the output signal of the proportional integration is multiplied by the output of the function generator 16 to feedback the reheated steam temperature to control the quantity of the RH spray. A switch 18 is provided between the PI calculator 17 and a multiplier 20, and another switch 19 is provided in a recycled gas control line to shift both control modes to prevent mutual interference

Title: Password recognizing device
Inventor: YOSHINO MASATAKA
IPC: G06F21/32
Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To reduce danger to apply the permission of use to the third person, who knows a user identifier, by correspondently storing and collating several kinds of user identifier information after a second character corresponding to keying state holding time in the case of inputting the leading character of the user identifier. SOLUTION: In a state of enabling the input of a password, a user holds the state of pressing the key of the leading character of the password just for time corresponding to the desired password. This time is measured by a time measuring part 104. When the password is inputted shorter than 1.0 sec, for example, the classification of 'short' keying time is decided and further, the password after the second character is continuously inputted. On the stage when all the character string of the password is completely inputted, an input content collating part 107 collates the contents with the registered contents for the classification of 'short' keying time and when they are matched, the permission of use is applied.  When the password is inputted longer than 1.0 sec and the classification of 'long' keying time is decided, the contents are collated with registered contents for the classification of 'long' keying time.

IPC: H04N1/411
Filed: 1984-06-05
Abstract: PURPOSE:To reduce the transmission time and to save recording paper by stopping the transmission of a white line when the white line is consecutive for a prescribed number or over. CONSTITUTION:The line information read by an image sensor 2 is amplified by a video amplifier 3 and then binary-coded by a binary coding circuit 4. Then the result is given to a line buffer memory 9 and to a white line detecting circuit 5. The presence of the white line is detected by the white line detecting circuit 5 and a white line number discriminating circuit 6 discriminates whether the consecutive white line numbers exceed the prescribed value. When the number is less than the prescribed number, the white line is transmitted to a reception side in the form of an abbreviated code and when it is over a prescribed number, the transmission of the succeeding white line is stopped. Thus, the transmission time is reduced and the recording paper is saved.

Abstract: PURPOSE:To prevent the warpage deformation of a holding plate, to improve the accuracy of the long dimensions of an electronic part while enhancing operating efficiency and to reduce cost required for coating by installing a magnetic substance extending over the whole rear of the holding plate. CONSTITUTION:A holding plate 10 is formed tabularly of a soft elastic body such as a rubber, a soft synthetic resin or the like, a sheet metal 11 is disposed in tension extending over the whole rear, the sheet metal 11 is made of a magnetic substance such as low carbon steel, stainless steel in low chromium or the like, and a large number of holes are bored.

Title: Acoustic echo canceler for voice communication equipment
Inventor: OBARA TAKASHI
IPC: H04L1/00
Filed: 1991-05-20
Abstract: PURPOSE:To shorten a period turning to the state of alternately repeating correct judgement and misjudgement for the detected result of double talk and to improve stability for double talk detection and echo cancel operations by providing a threshold value control means in addition to a double talk detecting means. CONSTITUTION:A double talk detecting circuit 110 is equipped with a threshold value control circuit 121. During the period when no double talk is detected, a high threshold value to easily detect the double talk is outputted from the threshold value control circuit 121. When the double talk is generated in such a state and a double talk state is detected at a comparator, the threshold value control part 121 does not immediately change the threshold value into a low value to easily detect the end of the double talk but holds the threshold value at the high value for double talk detection only for a prescribed period T corresponding to a transmission delaying amount. When a time over signal is outputted from a counter 122 after the lapse of the prescribed time T, the threshold value control part 121 changes the threshold value into the low value to easily detect the end of the double talk.

Title: Oscillation control method
Inventor: GOTO KENJI
IPC: B23Q11/00
Filed: 1988-05-13
Abstract: PURPOSE:To improve a response speed by setting a feedback quantity when the value to subtract a target value from the forecasting value of a power transfer system twist angle is not positive smaller than the feedback quantity when the value is position. CONSTITUTION:The oscillation control of an object, in which a power transfer system 14 is interposed between a driven body 12 and a power source 10, is executed. For the oscillation characteristic of a driving system 16, when a torque T is added to the power source of an inertia moment J1, a twist angle acceleration theta'' occurs and as the result, a twist angle speed theta' and a twist angle theta occur in the power transfer system. On the other hand, the twist angle speed theta' is detected by a control system 18 and a transfer constant C is negative-fed back. The transfer constant C is set so that the feedback quantity when the value to subtract the target value of a twist angle at the above- mentioned torque from the forecasting value at the torque T is not positive can be smaller than the feedback quantity when the value to subtract the above- mentioned target value from the above-mentioned forecasting value is positive. Thus, by using an initial acceleration sufficiently, the rise of the torque can be improved.
