Title: Method for predicting slab temperature in continuous type heating furnace
Inventor: HIRATA KENTARO
IPC: C21D9/00
Filed: 1993-03-09
Abstract: PURPOSE:To establish a means, by which the highly precise prediction of slab temp. in a furnace can efficiently be executed in on-line, by surely obtaining in a short time an overall heat absorptivity in plural zones in a continuous type heating furnace. CONSTITUTION:Error between a slab temp. measured value in an ejection hole and a slab ejecting temp. prediction value calculated from the furnace temp., time for staying the furnace, etc., of the continuous type heating furnace 1, is measured at each ejection of the slab 2. On the other hand, a sequential least square estimation is executed to an influence coefficient obtd. from the slab temp. calculation and the overall heat absorptivity phiCG in plural zones in the furnace is sequentially estimated in the on-line. Further, by renewing the overall heat absorptivity phiCG in each zone based on this estimated value, the predicting precision of the slab temp. in the furnace is improved. By this method, the slab temp. in the continuous type heating furnace is surely predicted.

Title: Facsimile system
Inventor: MANIWA YOSHIO
IPC: H04L29/06
Filed: 1981-05-19
Abstract: PURPOSE:To enable image information to be transmitted when the image information prepared in th transmitting side is not fitted to the size of recording paper in the receiving side by electrically converting the number of picture elements. CONSTITUTION:Image information read out by a image reader 1 is inputted to a data accumulator 3 through an encoder 2 and sent to the receiving side through a communication controllers 41-4n and line controllers 51-5n. Since the recording size of the receiving side is sometimes different from that of the transmitting  side, the information once stored in the data accumulator is read out, decoded by an decoder 6 and inputted to an image recorder 7. Then the information is converted by a picture element number converter 8, encoded again by the encoder 2 and stored in the data accumulator 3. Thus, the image can be transmitted independently of the recording side of the receiving side.

Title: Device for limiting charge on surface of solid
Inventor: OGATA SETOSHI
IPC: G01N23/22
Filed: 1980-06-04
Abstract: PURPOSE:To eliminate the charge on the surface of a specimen completely and to enhance the reproducibility of analysis of composition of the surface of the specimen, by detecting the charged state of the surface of the specimen, generating an electron beam from a low speed beam source other than that for analysis, and neutralizing the charge. CONSTITUTION:When the electron beam 2 is irradiated from an electron gun 1 to the specimen 5 to be measured, secondary electrons 12 are emitted from the surface of the specimen, and part of them enters into an energy analyzer 7. Under this state, the surface potential of the specimen 5 is measured by an oscillating electrode 6 and a charge potential measuring circuit 9. The charged state detecting signal from the circuit 9 is supplied to a power source circuit 10 through a control circuit 11 as a control signal. Based on the input signal, the circuit 10 irradiates the low speed electron beam when the charging potential from a gun 3 is positive and irradiates the low speed ion beam when the charging potential is negative. The beams from the gun 3 is irradiated on the specimen 5 until the output of the circuit 9 becomes zero. When a stabilized state is attained, the analyzer 7 begins the the measuring.

Title: Recording and reproducing unit
Inventor: SASAKI TAKAYUKI
IPC: H04N5/782
Filed: 1979-06-15
Abstract: PURPOSE: To reject the variation of carrying amount due to slip caused at the rising of carrying, by recording CTL pulse at the specified position during tape carrying and correcting the detection of rotary angle with this pulse.  
     CONSTITUTION: In taking the rotary angle of the motor 36 required for one tape carrying as 480 pulses for example, in the memory circuit 69, the latch circuits 53, 58, 66 store data 240, 360, -60 respectively and the counter 62 stores data -120. Accordingly, the motor 36 stops at the position corresponding to 120 pulses from the recording position of CTL pulse and to 480 pulses from the start of tape carrying. Further, since CTL pulse is recorded on tape, even if the amount of slip between the capstan and the tape is changed at recording and reproduction, the error can be corrected at the CTL pulse. Especially, the variation in carrying amount which often produced at the rising of carrying, can remarkably be reduced.

Title: Power takeoff controller for automatic transmission
Inventor: SUZUKI MISOZO
IPC: F16H63/38
Filed: 1988-03-31
Abstract: PURPOSE:To prevent a gear noise, a tooth break or the like from occurring by installing a means which regulates a power takeoff gear being slidden in a direction where it engages with a driving gear, and releasing the regulation of this regulating means only when rotational speed of the driving gear and it is less than the specified one. CONSTITUTION:When a driving gear 21 is rotated at more than the specified rotational speed, voltage to be inputted into a comparator 13 from a speed detecting sensor 11 via an FV converter 12 becomes high than the setting voltage, whereby positive voltage will not be inputted into a solenoid drive circuit 15, and a solenoid 16 is therefore excited at all. Consequently, a plunger 16a is engaged with a notch 17a of a shaft 17, so that even if a transfer lever is operated, this shaft 17 is no longer moved in the axial direction, thus engagement between a power takeoff gear 31 and the driving gear is checked. On the contrary, when rotational speed of the driving gear 21 is less than the specified valve, the plunger 16a is pulled out of the notch 17a, and the power takeoff gear 31 and the driving gear 21 are engaged with each other, and thus power takeoff is carried out.

Abstract: PURPOSE:To convert a power source circuit to a transistor by detecting a direct current of each transistor connected in parallel, detecting an average of each direct current, comparing each direct current with the average, and either raising an alarm in case a ratio of both of them exceeds a ratio determined in advance, or reducing a high frequency output. CONSTITUTION:Whenever the emitter of each transistor TR is scanned once by a switching circuit 6, a CPU7 calculates an inputted mean value EO of the emitter potential of each transistor, derives at every transistor a ratio XX= (E-EO)/EO to the mean value EO of a difference of an emitter position E of each transistor inputted in case of the following scanning and the mean value EO of the previous time, compares this X with a value XO set in advance, and operates an alarm means 9 such as a buzzer, etc. when a transistor of X>XO is detected. In case the alarm means 9 is operated, an operator reduces an output of a high frequency oscillator 1. Or the CPU7 reduces directly the output of the high frequency oscillator.

Title: Improvement of aeration tank
Inventor: TAMURA TAKAAKI
IPC: C02F3/12
Filed: 1980-06-06
Abstract: PURPOSE: To improve sewage purification capacity and eliminte the need for a final settling tank by providing an oxygen supply mechanism which allows part of the liquid in the aeration tank to contact high-concn. oxygen gas then returns the same to the aerating tank and a liquid height regulating weir in the aeration tank.  
     CONSTITUTION: An oxygen supply mechanism 12 has a duct 4 which extends along the liquid surface in an aeration tank 1 defined by a weir 11 and partly locates in  the liquid surface F. Part of the liquid in the tank 1 passes through a take-in port  41, is taken into a chamber 44 and enters an inside cylinder 52 through a chamber  55 and a communicating hole 57. The high concn. oxygen gas blown through an air diffusing pipe 58 is dispersed and absorbed by small bubbles into the liquid in the  inside cylinder 52, and gives gushing and soaring force to the liquid, so that the  liquid ascends in the inside cylinder 52 and flows into a chamber 43. Thence, the  liquid flows in the longitudinal direction of the duct 4 on a partition wall 42, and  flows into a settler 6. Durng this time, the separation of the bubbles contained in the fluid is accomplished and the liquid is returned from a directing pipe 62 to the tank 1.
