Title: Controlling for continuous kneader
Inventor: INOUE KIMIO
IPC: B29B7/72
Filed: 1985-06-05
Abstract: PURPOSE:To control the degree of mixing by catching the change of state of mixture on advance and consequently manufacture the mixture with stable quality by a method wherein the degree of mixing is controlled by comparing both temperatures of the mixture measured at the central part and the outlet part of mixing chamber part. CONSTITUTION:Firstly, material supplied from a hopper part 6 is continuously supplied through a screw shaft part 1a into a chamber part 7, in which the material is ground with shearing action by passing through gaps, each to which is made between the tip part of one of rotors and the inner surface of a chamber part, are melted. Secondly, the resultant molten material is spread through the back and forth shifting by kneader blades having twisting directions different from each other and the transfer of the material between the two rotors. Finally, the completely kneaded material is continuously discharged from a gate 8, the opening of which is variable. Thermocouples 15 to measure the temperatures T1, T2 and T3 of the mixture or said completely kneaded material are mounted at 3 positions or the outlet, center and inlet of the chamber part 7. The measured temperatures are compared with one another and the resultant instruction is transmitted through a control device to an opening changing device 13 in order to control the opening of the gate 8. Consequently, the hindrance due to time lag is prevented from occurring and the high quality mixture can be obtained.

Title: Exhaust gas desulfurization method
Inventor: TANIFUJI MINORU
IPC: B01D53/34
Filed: 1986-05-28
Abstract: PURPOSE:To effectively collect water vapor and fine particles by cooling SOX containing exhaust gas with absorption liquid supplied from an absorption tower in a cooling tower, and then having the same countercurrent contacted with the absorption liquid in the absorption tower and forcibly cooling the absorption liquid in the circulating process. CONSTITUTION:SOX containing exhaust gas is introduced from a duct 1 into a cooling tower A, contacted absorption liquid from a first absorption tower B and cooled down to lower than 80 deg.C. Then the exhaust gas is sent to the first absorption tower B together with vaporizing water vapor, countercurrent contacted with the absorption liquid to remove SOX. After being extracted by a duct 19 out of the lower section of the first absorption tower B, the absorption liquid is cooled down to lower than 60 deg.C by a forced cooling means D1 and circulated to the upper section of the first absorption tower B. The exhaust gas, coming out of the first absorption tower B, comes into a second absorption tower C and SOX is further absorbed. As the absorbed liquid is cooled down, part of water vapor in the exhaust gas is flocculated with dust and the like as core, and water vapor and fine particles are effectively collected.

Title: Memory device
Inventor: NISHIHARA TOSHIYUKI
IPC: G11C11/41
Filed: 1988-05-20
Abstract: PURPOSE:To provide full operation margin without increasing a channel length of a switching transistor or a channel width of a driver transistor and to gain high integration by making the carrier mobility of the switching transistor smaller than that of the driver transistor. CONSTITUTION:Carrier mobility of a switching transistor 12 of a memory cell is smaller than that of a driver transistor 13 of a flip-flop 11 of the memory cell. Therefore, even if the channel of the transistor 12 is not so long, the current driving capacity thereof is low, and it is accordingly unnecessary to increase the channel width of the transistor 13 to gain a desired current driving capacity ratio. As a result, a memory size can be reduced as a whole, thus realizing higher integration.

Title: Cleaner for bottom of water of swimming pools and so on
Inventor: FUKUI SHIGEJI
IPC: E04H4/00
Filed: 1977-10-13
Abstract: PURPOSE: To accomplish thorough cleaning of matters accumulaated on the bottom of water of a simming pool through backward, forward and reciprocating movements of the cleaner in a curve respectively different in direction by means of two sensors mounted thereto.  
     CONSTITUTION: A carrier 1 carrying thecleaner is sunk down on the bottom of water of a swimming pool and with a pump 6 driven, water is sucked in through a port 4. After the matters accumulsated are captured with a filter 5, the water is jetted out of port 7b. Thus, the cleaner moves forward. A part of the water is fed to a tube 22a, which is expanded eventually bringing the circumference thereof with the horizontal plane of a rotating body 16. Consequently, with the rotatio of a shaft 2a and a transmitting wheel 22, the body 16 turnes clockwise. In this manner, the carrier 1 advances in a slight curve. Upon contact of a sensor 8 with the wall C 2 ,  a valve V works to allow the water to jet out of a port 7a. Thus, the c leaner moves backward. Upon contact with the wall C 3 , a sensor 13 slides to the left reversing the direction in which the rotating body rotates. Thus, the cleaner reciprocoates in an opposite direction depicting the contrary curve from the walls C 3  and C 1 . In this manner, the cleaner moves back and forth and reciprocates in sequence until the bottom of water of the pool is cleaned up thoroughly

Title: Residual toner suction duct of electrophotographic copying machine
Inventor: TAKAHASHI YOSHIKAZU
IPC: G03G15/11
Filed: 1982-07-15
Abstract: PURPOSE:To increase the flow rate of air to a wall surface and to prevent toner from being stuck to and accumulate on the internal wall of a suction duct with small suction blower force, by forming spirally continuous projections on the internal wall of a suction duct. CONSTITUTION:Three groove parts 11 and three mountain range projection parts 12 are provided to the internal wall of the suction duct 7 to constitute the continuous projection spirally along the internal wall of the duct 7 as shown by a dotted line. When residual toner is sucked through the duct 7 together with air, the air containing the residual toner is rotated by the projections continuing spirally to reduce the flow rate of the air and no toner sticks to the internal wall. Even if toner particles stick to the internal wall, the air rotating spirally is blown up by turbulence and it is sucked through the suction blower. Therefore, the negative pressure in a cleaning device does not drop even during long- period use.

Title: Fsk demodulating circuit
Inventor: TAKEDA KOJI
IPC: H04L27/156
Filed: 1988-05-20
Abstract: PURPOSE:To enable high-accuracy demodulation by providing plural zero-cross interval measuring counters and a control circuit which makes plural zero-cross interval measuring counters start counting in order according to the detection of zero-cross points and outputs a selection signal. CONSTITUTION:A delay compensating circuit which delays a demodulation output is provided and the variance in delay time from the change point of a source binary signal to the demodulation output is reduced to reduce single-point distortion. Namely, a register 201 stores a zero-cross interval measured value at a present zero-cross point and a register 202 stores a measured value at a last zero-cross point; and a demodulation output deciding circuit 13 generates a demodulated signal 19 from the output of the register 201 and a demodulated signal 19 is led to the D input terminal of a demodulation output FF 14. When the demodulated signal 19 is a last demodulation output, the demodulated signal is not inputted to the FF 14, but delayed through a delay compensating circuit 203 by a delay time determined by the values of the outputs 204 and 205 of the registers 201 and 202 and then inputted to the FF 14 with latch pulses 206. Thus, the demodulated signal is delayed properly and outputted to obtain a demodulation output having extremely small single-point distortion, thereby performing high-performance demodulation.
