Title: Method and apparatus for controlling pressure of combustion furnace
Inventor: NAKAMURA SHIGEAKI
IPC: F23G5/50
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To conduct accurate pressure control of a combustion furnace in respect of quickly changing furnace pressure by measuring the furnace pressure in a time-series manner, predicting variation of the furnace pressure on the basis of the time-series data of the measured values, and conducting precedent control of at least one damper opening on the basis of the predicted values. SOLUTION: Pressure of a stoker furnace 1 is measured in real time by means of a furnace pressure measuring instrument 2 located at the upper portion of the furnace 1 to transmit signals resulting from the measurement to a predicting means 28. Subsequently, the predicting means 28 predicts the furnace pressure variation of a given time later which corresponds to the time delay of a damper, on the basis of the time-series data. Following the prediction, signals of predicted variation of the given time later obtained by the predicting means 28, are transferred to a controller 26. Further, an induced blower entrance damper 21 is operated on the basis of the opening signals formed in the controller 26, so that the data measured by the furnace pressure measuring instrument 2 approaches the values of not more than a set value to control the furnace pressure.  Thus furnace pressure control of good accurateness can be realized even for the quickly changing furnace pressure.

Title: B-class amplifying circuit
Inventor: SAKAI KAZUMASA
IPC: H03F3/30
Filed: 1979-03-30
Abstract: PURPOSE:To improve the switching distortion by dividing the cut-off state for the output transistor. CONSTITUTION:With application of the input signal voltage with the potential increasing at point A, output transistor 1 performs the amplifying action to increase its emitter current. In this case, the increased amount of the base current flows through the collector and the emitter of driving transistor 3 plus resistance 9. Thus the voltage drop of resistance 9 increases, and the potential difference decreases between points B and C. Here the current flowing through resistance 10 decreases, but no cut-off state is caused to driving transistor 4 owing to existence of the current flowing through resistance 32. Also output transistor 2 has no cut-off state. In the same way, the cut-off state is never caused to transistor 1 even when the input signal voltage may change and the input signal voltage may be applied in the direction where the voltage of point B lowers.

Filed: 1988-02-23
Abstract: PURPOSE:To input a range of mask while confirming it on the screen by providing a liquid crystal shutter plate shielding a projected light of mask range set by an input means inputting the mask range of the projected image. CONSTITUTION:The entire face of a liquid crystal shutter plate 50 is made translucent to project the entire projection image of a film 18 onto a screen 28 and the mask area is inputted by a touch sensor 48 on the front face while observing the screen 28. For example, the coordinates B, C are entered by touching a finger or an exclusive input pen to the upper left corner B and the lower right corner C of the required range A. In case of masking an undesired part D in the range A, coordinates of corners E, F of upper left and lower right of the part D are entered similarly. The coordinates are read by a CPU 34, which discriminates the mask range according the control program stored in advance, makes the corresponding range of a shutter plate 50 opaque based on the coordinates of the mask range thereby shielding the light of this range. Thus, only the required range A appears on the screen 28.

Title: Preventing system for transmission of interference wave
Inventor: SUZUKI YOSHIAKI
IPC: H04B17/18
Filed: 1982-03-11
Abstract: PURPOSE:To prevent the interference to other channels due to a shift of frequency, by cutting off the power supply of an amplifier of the final stage based on the generation of an alarm which is produced when a shift of transmission frequency is detected by a multiplex radio device, and decreasing the transmission output. CONSTITUTION:The oscillating frequency fL of a voltage control oscillator 1 is changed with some reason, and accordingly the frequency fS of an RF signal output is also changed. In this case, the DC signal output corresponding to the difference between both input frequencies fL/N and fR/M which are produced from a comparator 9 is applied to a frequency shift detecting circuit 12 and compared with a fixed level of DC threshold voltage. Then the circuit 12 produces an alarm signal when the DC signal the comparator 9 has a larger level than the threshold value and then opens a switch 8. As a result, an amplifier 5 of the final stage loses its power supply to lower greatly its gain. In such a way, the power supply of the amplifier 6 is cut off the frequency of the RF signal output has a shift due to a shift of frequency of a local oscillation signal. This prevents the transmission of the RF signal having a shift of frequency.

Title: Lock-up controlling apparatus for lock-up torque converter
Inventor: HARUHARA YOSHIO
IPC: F16H61/14
Filed: 1978-04-04
Abstract: PURPOSE: To lock-up only when both shift position and vehicle speed fulfill prescribed conditions in relation to the vehicle speed by constituting a lock-up controlling apparatus from a first spool valve and a second spool valve.  
     CONSTITUTION: As front clutch pressure B is not supplied to a first spool valve 30 until the speed shifts from the second to the third, even if the vehicle speed reaches above 40 Km/h in low load driving range, lock-up does not arise, and a sufficient speed is obtained with the slip of a torque converter 1 unitl speed shifts and lock-up arises. In high-load driving range, as ports 36 and 47 communicate in a vehicle speed of 40 Km/h, lock-up arises at the same time when speed shifts from the second to the third. Due to the orifice 47 of a secondary spool valve 31, the decompression of a lock-up oil chamber 27 is relatively relaxed, and the impact due to clutch connection is relaxed, and the shock due to speed change in lock-up state is prevented.
