Title: Heat recovery method and device which absorb steam from gas and recover heat
Inventor: YOOZEFU SHIYUTOUUBENFUORU
IPC: F23J15/00
Filed: 1984-09-28
Abstract: Flue gases (6) discharged from a flue gas desulfurizer (5) are fed to an absorption tower (7) and the heat recovered by the absorption is transferred to the flue gases and/or the absorbent (8). The water which has been absorbed by the absorbent is expelled therefrom as vapor by desorption, e.g., by a stripping with flue gas in a preliminary scrubber (44), which precedes the flue gas desulfurizer (5). By means of a pump (16) the absorbent (8) is circulated between the absorption tower (7) and the preliminary scrubber (44). The flue gases (4) discharged from the boiler furnace (1) flow through an air preheater (2), the preliminary scrubber (44), the flue gas desulfurizer (5) and the absorption tower (7), in that order, and are then discharged into the open through a chimney (19). The combustion air (3) is supplied to the boiler furnace (1) through a heat exchanger (45) incorporated in the circulating system for the absorbent (8) and through the air preheater (2).

Title: Air conditioner
Inventor: KAWAGUCHI YUJI
IPC: F24F11/02
Filed: 1987-08-19
Abstract: PURPOSE:To protect outdoor electric parts even if the temp. in an outdoor electric box rises up abnormally by a method wherein an indoor power relay controlling voltage supplied to the parts is so controlled as to be cut off when an abnormal temp. rise at the outdoor side is detected. CONSTITUTION:A temp. fuse 13 is placed at an outdoor interface part. When the temp. in an outdoor electric box rises up abnormally and the fuse 13 is cut off, an I/F signal transmitted from the outdoor side to the indoor side continues to keep LOW condition. An indoor control circuit 3 judges that the I/F signal transmitted from the outdoor side to the indoor side keeps LOW condition for a second and, at that time, a power relay 4 is OFF and an operating display is turned on and off at a pitch of constant time. At the stop time of an outdoor apparatus caused by overcurrent, etc., the LOW condition of the I/F signal transmitted from the outdoor side keeps only for 230mSec and this case therefore does not belong to this mode and the power relay is cut off after 3 minutes and can be ON again on a later main operating ON signal.

Title: Method for forming colored pattern on surface of japanese paper
Inventor: SANO SAKAE
IPC: D21H19/00
Filed: 1991-07-19
Abstract: PURPOSE:To form a colored pattern on the surface of Japanese paper without impairing hand unique to the Japanese paper by narrowing the width of the Japanese paper from the opposite directions until the area of the Japanese paper attains a prescribed area, forming unevennesses, subsequently extending the Japanese paper until a prescribed area is attained and then spraying a vegetable dye thereon. CONSTITUTION:The width of Japanese paper placed in a spread state on a workbench is narrowed from the opposite directions until its area attains about 1/2 to form random unevennesses on the surface of the Japanese paper, which is then extended until the area attains about 2/3 of the original area. Thereby, uneven creases are formed on the surface of the Japanese paper. A vegetable dye is subsequently sprayed on the Japanese paper in a state of the existing uneven creases from the directions in which the width is narrowed. As a result, a colored pattern such as a linear ombre pattern is formed on the surface of the Japanese paper.

Title: Measuring device for air-fuel ratio of engine
Inventor: KITAHARA TAKESHI
IPC: G01N27/407
Filed: 1981-12-18
Abstract: PURPOSE:To enable to normally hold an oxygen partial pressure at a reference oxygen pole side in a constant manner, by a method wherein, based on an output of an oxygen sensor, a voltage, which is substraction of a constant voltage from the oxygen sensor output or addition of the constant voltage to it according to a relation between an air-fuel ratio and a theoretical air-fuel ratio, is smoothed, and a current, proportioning an absolute value of the positive or the negative smoothing voltage, flows out from or flows in the oxygen sensor. CONSTITUTION:Corresponding to an oxygen density in exhaust gas, a sensor output is high at a thick air-fuel side and is low at a thin side. A comparator 61 outputs a high level voltage at the thick side, and outputs a low level voltage at the thin side. Thus, a feed back amplifier 71 outputs a voltage which is substraction of a constant voltage DELTAV from a sensor voltage at the thick air-fuel ratio side and reversely is addition of the constant voltage DELTAV thereto. The output is smoothed by a capacitor 74 to produce a smoothing voltage Va. If the smoothing voltage Va is minus, an operational amplifier 65 outputs a positive current Is to a reference oxygen pole 15. If the smoothing voltage Va is plus, it, reversely, flows out the current Is, proportioning the absolute value of the Va, from the reference oxygen pole 15.

IPC: B41J2/44
Filed: 1990-07-31
Abstract: PURPOSE:To attain strength with respect to environmental fluctuations and to easily carry out optical adjustment by carrying out digital output at a slice level different from the slice level of light whose incident light quantity is monitored. CONSTITUTION:When a photodiode 2 on which a reverse bias is applied by a resistance 14 is irradiated with the rays of the light, a photoelectric current is generated, and supplied to a current mirror 9, and a current in proportion to the size of the emitter of the transistor of the current mirror 9 flows from resistance 13 to the current mirror. At this time, a constant voltage drop occurs on the resistance 13, and a voltage that the dropped voltage is subtracted from a power source voltage is generated on a terminal 10. Then, the voltage given to a voltage follower 5 is outputted to a photoelectric current monitor signal terminal 4 as it is, and the voltage given to a hysteresis comparator 6 is compared with a reference voltage produced by resistance 7 and 8 and outputs a horizontal synchronizing signal to output 3 according to the compared result. Further, adjustment is carried out while monitoring the photoelectric current monitor signal 4 and recognizing that slicing is not curried out in a state where a margin does not exest, at the time of the adjustment. Thus, the strength with respect to the environmental fluctuations is attained and the optical adjustment is easily carried out.
