Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To eliminate the occurrence of a disorder in an array for transfer and keep an array along a lateral row even on a carrying conveyor, similar to an array on a transfer conveyor by applying the constitution that the extension lines of a specific picture element having a specific value on the bent surface of a curved belt are converged on the center point of the outer circular arc thereof SOLUTION: This conveyor is so constructed that four extension lines of a specific picture element appearing on the bent surface of a curved belt 1 is converged on the center point of the outer circular arc thereof. In other words, a carrier roller 2' and a return roller 3' are arranged so as to converge the extension lines of the specific picture element of the curved belt 1 on the center point of the outer circular arc thereof via the operation of an adjusting mechanism. As a result, the edge of the curved belt 1 comes to be positioned on virtual lines radial completely from the center point at both inlet and outlet sides, thereby eliminating the delay of the arrival time of both inner and outer sides of the curved belt 1.

Title: Clutch facing
Inventor: HATA TAKASHI
IPC: F16D69/02
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To suppress swelling in a manufacturing process and to achieve mass reduction by mixing high strength hollow ceramic filler of 3%-20% with a base material. SOLUTION: Loss of a high strength hollow ceramic filler can be usually suppressed under about 3% for a pressure of about 100-200 Kgf/cm2. Therefore, it does not swell during high pressure molding in a manufacturing process of a clutch facing and mass reduction can be achieved. If a mixing amount of the high strength hollow ceramic filler is less than 3%, the mass reduction cannot be achieved sufficiently. If the mixing amount exceeds 20%, friction of a counter surface (frictional surfaces of a flywheel and a pressure plate) is un-preferably accelerated. By setting the mixing amount of the high strength hollow ceramic filler 6%-12%, friction coefficient in a low temperature region increases. If the mixing amount is less than 3%, friction coefficient does not increase comparing with no-addition.

An ion exchange apparatus 3 filled with a weakly acidic cation exchange resin is installed in one circulation line to prevent scale generation in the ion exchange membranes of the deionization devices 2, 6. When the conductivity of treated water in the devices 2, 6 has exceeded a prescribed value, the ion exchange membranes are washed by passing a strong acid solution. At a time point when the hardness of treated water in the ion exchange apparatus 3 has exceeded a prescribed value, the regeneration of the weakly acidic cation exchange resin is performed.

IPC: B60K23/08
Filed: 1987-09-29
Abstract: PURPOSE:To enhance the heat-resistance of friction pads in a transmission for an automatic transmission vehicle, by disengaging a clutch for a predetermined time when a sensor detect a high speed running condition of the vehicle. CONSTITUTION:In a normal running condition, a selector valve 33 falls in a communicating condition to apply a hydraulic pressure in accordance with the operating condition to a hydraulic actuator 27 so as to engage a wet type friction pad clutch. When sensors S1, S2 detects that the vehicle comes into a high speed condition, a control panel 80 actuates a solenoid valve 32 to change over the valve 33 so as to drain the hydraulic actuator 27 in order to disengage the friction pad clutch intermittently or continuously for a predetermined time. With this arrangement, lubrication oil flows between a friction plate and a separator in the clutch to lower the temperature of the friction pad. Thus, it is possible to enhance the heat-resistance of the friction pad.

The probability X of the unpolished rice is obtained from the value V. The probabilities X obtained are successively added, and the addition is continued until the number of the grains detected amounts to a specified number N, e.g. 100. When the number of the grains detected amounts to N, the hulling rate is calculated from the ratio of the total number of the probabilities to N, and the calculated hulling rate is indicated on an indicator 6. The degradation of precision in detecting the hulling rate due to misjudgment is prevented in this way.
