Title: Running speed change structure of work vehicle
Inventor: FUKUI SATORU
IPC: F16H61/28
Filed: 1990-06-05
Abstract: PURPOSE:To suppress a shock and shorten a speed change operation time as a whole by providing the first control means for off-operating a first clutch by reducing its operating pressure and a second control means for in-operating the clutch by gradually increasing the operating pressure. CONSTITUTION:Since a second clutch 19 is placed in a perfect off-condition by rapidly off-operating the second clutch 19 through speed change operation by actuators T1, T2, T3 to decrease an operating pressure in a first clutch 6 to a predetermined low pressure, a transmission off-condition is obtained as a running system total unit. Accordingly, the speed change operation is performed without a trouble. When the speed change operation is finished, the second clutch 19 is rapidly in-operated, and power transmission is not performed because the first clutch 6 is placed in a not perfect off-condition. Thereafter, a time required before the in-condition is shortened when the first clutch 6 is in-operated by increasing its operating pressure. Since the operating pressure of the first clutch is gradually increased, a shock is reduced when the first clutch 6 is placed in the in-condition.

Abstract: PURPOSE: To enable to easily stabilize a pH of treated water near to neutral by adding to and depositing on a substance having buffer action to particularte activated carbon.  
     CONSTITUTION: A substance having buffer action such  as disodium phosphate or the like is added to and deposited on particulate activated carbon in a ratio of about 1W0.001% pre, about 0.1W0.01% in a form of an aqueous solution or the like. When a waste water such as a usual waste water or the like is treated by using the obtained added and deposited particulate activated carbon, treated water of which a pH is always stabilized near to neutral is obtained. Therefore, pH readjustment carried out in conventional treated water is not necessitated. Said added and deposited particulate activated carbon can be used in treating sewage treatment and special industrial waste water other than usual waste water treatment.

Title: Temperature compensation method for gas electrode type hydrogen detector
Inventor: KISHIDA TAKUYA
IPC: G01N27/26
Filed: 1987-06-15
Abstract: PURPOSE:To make it possible to measure the concentration of hydrogen gas in a broad temperature range, by correcting the output of a detector by using a specified correcting term. CONSTITUTION:A gas electrode electrolyte 12 is brought into contact with a gas electrode 11. A reference electrode electrolyte 14 is brought into contact with a reference electrode 13. The electrolyte 12 and the electrolyte 14 are brought into contact through a diaphragm 15 in the title detector. The output E(T) of the detector at the temperature T(K) of the detector is corrected by a formula (II) by using a correcting term f(T) expressed by a formula (I). Thus the normalized output EN of the detector at the specified temperature is obtained. In the formulas: Tm is the average temperature of the detector during a specified period before a point of measuring time; g(T-Tm) is the linear expression of a temperature difference (T-Tm); and h(Tm) is a higher-order expression of Tm. In this method, since temperature-compensated detector output is obtained, the concentration of hydrogen in a broad range of temperature can be measured.

Title: Optical phase modulator
Inventor: TAKEUCHI YOSHINORI
IPC: G02B26/06
Filed: 1990-06-05
Abstract: PURPOSE:To obtain a flat optical phase modulating characteristics by forming electrodes on the inside and outside of a cylindrical piezoelectric vibrator having no symmetrical axis or symmetrical plane and winding up an optical fiber around the vibrator. CONSTITUTION:The cylindrical piezoelectric vibrator 11 whose outline is a cylinder has a cylindrical cavity 12 having a center axis different from the center axis of the outline cylinder and the optical fiber 13 is wound around the outer periphery of the cylinder. The vibrator 11 in the length direction is cut off by a plane not intersecting with the center axis of the outline cylinder at right angles. The electrodes 14, 15 are formed on the inside and outside of the vibrator 11, and when oscillation voltage is impressed between the electrodes 14, 15, the vibrator 11 vibrates in the diameter direction. In this case, the center axis of the inside cylindrical cavity 12 is eccentric and the thickness of the cylinder is not uniform. Also the wall thickness of the vibrator 11 in the length direction is not uniform, preventing the generation of remarkable resonance in an oscillation mode. Thus, the flat frequency characteristics of optical phase modulation can be obtained.

Title: Ribbon for heat transfer
Inventor: FUNAYAMA NOBUTAKA
IPC: B41M5/41
Filed: 1990-06-06
Abstract: PURPOSE:To obtain a ribbon for heat transfer with excellent printing performance by specifying a rate of change in dimension with respect to a temperature and an original length of a biaxially oriented polyester film at a point where gradient changes from negative to positive in a horizontal temperature dimension varying curve thereof. CONSTITUTION:Biaxially oriented polyester film has a point (minimal point) at which gradient changes from negative to positive in a horizontal temperature dimension varying curve of the film when the curve is measured and a rate of change in dimension is -5-+5% with respect to an original length of the film at the minimal point with the temperature at the minimal point exceeding 200 deg.C. When the temperature at the minimal point is lower than 200 deg.C or the rate of change in dimension at the minimal point is lower than -5% even with the temperature exceeding 200 deg.C, shrinking of the film during the printing increases to cause wrinkles in the film, which disables printing. When the rate of change in dimension at the minimal point is larger than +5%, the elongation of the film increases as caused by heat applied in the coating of an ink layer and a rear treated layer to make the film sag. which causes a coating spot. This eliminates a wrinkling in the ribbon for heat transfer during the printing thereby enabling the obtaining of a clear print.
