Title: Coating film remover
Inventor: KASAI NORIHIRO
IPC: C09D9/00
Filed: 1994-06-24
Abstract: PURPOSE: To obtain a coating film remover for metallic materials, less affecting the environment and the human body and having high removing capacity by adding a specified concentration of an acid to a nonhalogen organic solvent.  
     CONSTITUTION: There is provided a coating film remover containing an acid in a concentration of at least 0.01 mol/L in a nonhalogen organic solvent. The nonhalogen organic solvent used means an organic solvent free from a halogen atom having high chemical stability such as chlorine or fluorine. The reason why such an organic solvent is used is that it is generally lowly toxic, does not produce halogens or halogen compounds when heat-decomposed, and therefore it affects little the environment and the human body. The boiling point of the solvent used is desirably 50°C or above. Because it does not undergo marked evaporation during storage or use, the dispersion of its removing capacity due to uneven concentrations can be prevented, and because the flammability is lowered, the safety can be improved. Examples of the organic solvents used include methyl ethyl ketone, acetone, methyl isobutyl ketone, and tetrahydrofuran.

Title: Vibration controller for railroad rolling stock
Inventor: UCHIYAMA MASAAKI
IPC: B61F5/24
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To provide a vibration controller for railroad rolling stock which can control the displacement in the transverse direction of a carbody in a good condition even when it runs on a cant road. SOLUTION: When a block B4 in which a ground point information signal Ad is input judges that a railroad rolling stock runs on a cant road, a block B6 makes a variable Ja for sky hook control zero. On the other hand, a variable Jb for cant control is made one to inhibit the sky hook control including the integration processing of acceleration α in the transverse direction. Moreover, the cant control including blocks B5A, B5B which calculate target attenuation force so that it becomes the attenuation force by which a carbody is not swinged to the outside and inside of the cant road is adopted to obtain desired attenuation force which corresponds to the cant road (inclination angle, etc.).  Since the sky hook control including the integral processing of the acceleration αin the transverse direction is inhibitted when the railroad rolling stock runs on the cant road, the reduction of integration precision in accordance with excessive centrifugal acceleration at the time of running on the cant road which occurs with the conventional technique does not occur, and the vibration suppression control can be improved.

Title: Logarithmic conversion circuit for insulation resistance meter
Inventor: HAYASHI EIJI
IPC: G01R27/02
Filed: 1979-11-06
Abstract: PURPOSE: To contrive so that stable operation may be maintained, even if a measured resistance value is almost infinite by utilizing the logarithmic change characteristics of two PN bonded elements which are thermally in an equilibrium.  
     CONSTITUTION: When the value of a measured resistance is almost infinite, a voltage signal to be inputted from an input terminal 1 is proportional to a reciprocal  number, so that the voltage is almost at the point of OV. For this reason, the impedances of two diodes D 1 , D 2  which are PN bonded elements and are thermally in  an equilibrium are exceedingly higher than those of their respective resistors R 2 , R 3 .  Therefore, it is considered that the diodes D 1 , D 2  are nonexistent. In addition, a  capacitor C is for smoothing purpose, so that the substantial action of this circuit is  not affected. Accordingly it is considered that said capacitor is also nonexistent. In  this case, the circuit will be of such constitution that two simple inversion amplifiers are connected in series. Thus it is possible to carry out a stable operation, even  if a measured resistance value ar almost infinite.

Title: Controlling device for water level fluctuation in suction water tank
Inventor: ISHIKAWA YOSHIHIDE
IPC: F04B49/02
Filed: 1978-11-24
Abstract: PURPOSE: To miniaturize a suction water tank and moreover to suppress deterioration in efficiency at starting up and shutting down a pump and occurrence of oscillations and noises by controlling a discharge valve so as to keep a fluctuation of the water level coming in a constant width in accordance with a detection signal for the water level fluctuation.  
     CONSTITUTION: A fluctuation of the water level in a suction water tank 1 is outputted as a detected water level width signal by a water level signal generator 8 and is inputted in an arithmetic unit 9 to decide, as illustrated, whether or not the detection signal (in full line) comes in the water level width (in broken line) preset for steady operation of a pump. If it comes outside the preset level, a difference between the preset water level width and the detected water level width is calculated, and the result is sent to a function generator 10. A valve controlling device 12 therefore turns to control a discharge valve 6 so as to equalize an output from the function generator 10 and an output from a valve opening meter 11, thereby suppressing the water level fluctuation in the suction water tank 1 within a constant width.

Title: Coating method and device for resist on both side surfaces of wafer
Inventor: TANAKA TSUTOMU
IPC: H01L21/027
Filed: 1980-10-17
Abstract: PURPOSE:To control the thickness of a film by horizontally holding a wafer to be coated with resist, blowing the resist to both side surfaces of the wafer while rotating the wafer at a low speed, then rotating it at a high speed to form a thin uniform film, thereby preventing the contaminated defect of the coating resist. CONSTITUTION:The periphery of a thin disc-shaped wafer 17 is horizontally held with three pawls 30 of a chucking mechanism, the periphery of the chucking mechanism is surrounded by a cover 33, and a nozzle 24 is raised to an E line. The resist is sprayed to both side surfaces of the wafer 17 while rotating the mechanism and the wafer 17 around the vertical rotating axis by a rotating mechanism 21 at a low speed. When the rotating speed is then accelerated, the resist adhered to the wafer is reduced to thin film to scatter the excessive resist. In this manner, the resist can be formed in a desired thickness without contaminating nor damaging the coated surface.
