Title: Control device for excitation of water wheel generator
Inventor: IHARA ISAMU
IPC: H02P9/30
Filed: 1982-07-19
Abstract: PURPOSE:To eliminate the generation of fluctuation to a system by trially charging completely the system, then allowing the set voltage value of a field voltage regulator to be coincident to the set voltage value of an automatic voltage regulator and then shifting to the generating operation by the regulator. CONSTITUTION:When a changeover switch is trially operated at the charging side, a holding relay 22 is operated, a holding relay 24 is reset, an automatic voltage regulator 4 is turned to OFF, and a filed voltage regulator 7 is turned to ON. Thus, the trial charge of the system is started. When the trial charge of the system is completed, a voltage relay 10 is operated, an automatic voltage aligning unit 9 is operated, and the set voltage value of a field voltage setter 8 is raised. When the set voltage value of the setter 8 is coincident to the set voltage value of the generator voltage setter 5, the holding relay 22 is reset, the relay 24 is operated to excite the water wheel generator 1 by switching the control by the field voltage regulator 7 to the control by the automatic voltage regulator 4.

Title: Heating and cooling method for cold trap and pipe line
Inventor: FUKUSHIMA SEISUKE
IPC: B01D7/02
Filed: 1977-10-19
Abstract: PURPOSE: To stop the operation of a cold trap (CT) with the temp. of CT kept lower than that of pipe lines when abnormality of pipe line heaters has arisen, by stopping the heating of the CT rapidly and by starting the cooling of the CT to cool it below room temp.  
     CONSTITUTION: When sublimable material solidified in a CT is heated to sublimate and is recovered through a withdrawing valve 21, if the temp. of pipe lines 2, 3 connecting to the CT 1 becomes lower than that of the CT1 1, the sublimated material solidifies at the lines 2, 3 and clogs the lines 2, 3. Therefore, the CT 1 must be operated with its temp. kept lower than that of the lines 2, 3. When any abnormality arises in the pipe line heaters 6, 7, the pipe line temp. varies at a rate 10W 1,000 times that of the CT 1 if only the operation of high-temp. fluid line 10W14 is stopped, and the pipe line temp. tends to become lower than CT 1 temp. Hence the CT 1 is cooled rapidly to a temp. lower than roon temp. by use of a low-temp. fluid line 11W15, hereafter the cooling is stopped

Title: Method of controlling air-fuel ratio
Inventor: KAJI TAKASHI
IPC: F02D41/34
Filed: 1981-08-11
Abstract: PURPOSE:To prevent hunting and engine stall by detecting the active state of an air-fuel ratio sensor to carry out limitation of the feedback control range. CONSTITUTION:In a control circuit 20 which receives signals from sensors 11-14 for sensing the suction quantity, suction temperature, water temperature and O2 to control electromagnetic type fuel injection valves 51-56, it is first judged whether the sensor 14 is in an active state or not or whether the feedback control is possible or not. When it is judged that the feedback control is possible  and it is also judged by a timer 11 that a unit time DELTAt1 is passed, the previous  correction quantity K2 is increased or decreased depending upon whether the signal of the sensor 14 is rich or lean, the limit value 2 is obtained by the table  from the passing time after the idling switch is turned ON. If the correction  quantity K2+K is more than the limit value, it is corrected by use of the limit  value. By this procedure, when the response of the sensor 14 has been deteriorated, the variation in the engine rotational speed can be suppressed.

IPC: B62D25/20
Filed: 1997-04-29
Abstract: PROBLEM TO BE SOLVED: To thin down the board thickness of a floor panel as keeping up its high rigidity by enlarging the width of a projection top face in a central part of this floor panel gradually toward the rear. SOLUTION: A rear area 15b of a projection top face 15a in a central part 15 of a floor panel 4 is made contact with another projection top face 16a of a rear part 16 as gradually enlarging width W1 in the cab width direction W. The projection top face 15a of the central part 15 is flush with the projection top face 16a of the rear part 16 in terms of height, and in this case, both of them may be formed into a state of forming one plane, and also both these top faces 15a and 16a may be constituted so as to make them differ in height more or less. If the central part 15 is constituted like this, the whole sectional structure of the floor panel 4 becomes complicated, so that both of flexural rigidity and torsional rigidity of the floor panel 4 are heightened.  Accordingly, the board thickness of this floor panel 4 can be set up to be smallish as maintaining the high rigidity of the floor panel 4, whereby weight of the floor panel 4 as well as the cab is reducible in consequence.

Title: Water glass for welding material
Inventor: SEIKE NORIO
IPC: C03C4/00
Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To obtain the subject water glass useful for the fixation of a coating agent and improvement in adhesiveness between the coating agent and a core line in a coated arc welting rod, capable of improving the coating performances of the coating agent to the core line when the coated arc welding rod is prepared and the falling off resistance of the coating agent, by specifying the electric conductivity of the water glass. SOLUTION: This water glass for a welding material is made to have 1.0-7.0(S/m), preferably 2.0-6.0(S/m) electric conductivity at 25 deg.C measured by a method prescribed by JIS KO101-1991. Namely, the coating performances of a coating agent to a core line is influenced not by a chemical component of a water glass (e.g. SiO2 , Na2 O, K2 O and Li2 O) but by the existence form of various ions present in the water glass and the existence form is investigated by the measurement of the electric conductivity. Consequently, when the electric conductivity is lower than 1.0(S/m), the amount of the free ions is excessively reduced and adhesiveness becomes insufficient and when exceeds 7.0(S/m), the amount of the free ions is extremely increased and the coating performances are deteriorated.

Abstract: PURPOSE: To realize not only the simplification of the spray coating process but a reduction of the coating shift, by giving a control to each spray head based on the coating data read out of the pattern storage part by the output of the transfer detection part which detects the rotating angle of the paper feed roll.  
     CONSTITUTION: The rolled long-size paper 1 is rewound by the paper feed roll 2 to be transferred toward the arrow X. The rotating angle of the roll 2 is detected by the transfer detection part 3 consisting of the paper feed distance calculation disk 7 having the through-holes 8 equidistantly at the fringe area provided to the shaft 10 of the roll 2 and the photoelectric switch 9 having the opposing light projection/reception parts 9a and 9b. And the output of the part 3 is obtained in the form of the pulse every time the roll 2 has a turning motion by a fixed angle and then the paper 1 is shifted by the unit length. The coating spray heads 4aW4e arranged equidistantly in the direction vertical to the shifting direction X receive the ON/OFF control by the coating data which are read successively out of the pattern storage part and by the output of the part 3. Thus the desired spray coating pattern is formed.
