Patent JP-S6241428-A (JP)
Title: Clutch disk
Inventor: KONO SATOSHI
IPC: F16D13/64
Filed: 1985-08-15
Abstract: PURPOSE:To sufficiently exhibit damping capacity against torque fluctuation to prevent damping efficiency from lowering by forming the annular concave and convex part of a clutch disk, in which the shearing resistance of a fluid is utilized for damping of a torsional vibration, more outward than the arranged position of a compression spring. CONSTITUTION:When an input member 5 makes turning motion in the circumference direction around an output member 3 by a driving torque from an engine, both ends of each compression spring 6 arranged in a fluid-tight space are compressed by the circumference direction end part of a housing part 9 for a spring. Consequently, a driving torque is transmitted to the output member 3 through the compression spring 6. Then, the driving torque is absorbed by a spring reaction force of the compression spring 6. Likewise, simultaneously a working fluid inside a fluid-tight space comes to be sheared while having a desired shearing resistance due to an annular concave and convex part 10, 11 formed in each opposing face of the input member 5 and the output member 3, therefore, due to an energy loss of the working fluid which is caused at this time, a torque fluctuation from a driving system is lowered efficiently.

Title: Charge controller for secondary battery by dynamo
Inventor: SHIBUYA SEIICHI
IPC: H02J7/14
Filed: 1990-07-06
Abstract: PURPOSE:To facilitate the detection of deterioration in a secondary battery by making a dynamo charge the secondary battery when a capacitance shortage detecting means detects a shortage of a capacity of the secondary battery. CONSTITUTION:A battery 42 uses a nickel-cadmium battery as chargeable secondary battery and an output of a dynamo 10 is inputted into the battery 42 after subjected to a whole wave rectification with a whole wave rectifier 43. Resistances 65 and 66 are connected to the battery 42 while a voltage value to be divided with the resistances 65 and 66 is inputted into an input port 67 of a microcomputer 44 to detect shortage of capacity of the battery 42. Then, when the shortage of capacity of the battery 42 is detected (by a capacity shortage detecting means, control means and judging means), the microcomputer 44 lets the dynamo 10 charge the battery 42 and when the shortage of capacity is detected again within a fixed time after the charging of the battery 42, the battery 42 is determined to be unable to be charged. As a result, a drop in charging/discharging capacity is detected by the life of the battery 42 only by a soft processing of the microcomputer 44 without providing a load for drop in voltage especially.

Title: Differentiator having digital integrating function
Inventor: NAGAI HIDENORI
IPC: G06G7/18
Filed: 1980-12-22
Abstract: PURPOSE:To ensure the even accuracy regardless of the level of a input voltage, by providing a digital integrating function by an up-down counter and applying negative feedback to an operational amplifying circuit. CONSTITUTION:Receiving a voltage input signal Vi, an operational amplifying circuit part 2 delivers a voltage output signal Vo'. This voltage Vo' is applied to an absolute value amplifier 3a and a voltage comparator 3d of an integral arithmetic circuit part 3. Thus an output ¦Vo'¦ is obtained from the amplifier 3a and then applied to a voltage frequency converter 3b to obtain an output SF having a pulse frequency proportional to the voltage ¦Vo'¦ through the comparator 3b. On the other hand, the comparator 3d discriminates the plus or minus of the voltage Vo' and applies a control input signal to a counter 3c. The counter 3c performs the up-counting and down-counting for the output SF when the voltage Vo' is plus and minus respectively. The output of the counter 3c is fed back to the circuit part 2 via a D/A converter 3f. As a result, no error is produced although the input voltage is particularly high.

IPC: H01L21/304
Filed: 1990-07-10
Abstract: PURPOSE:To prevent a characteristic of a fine VLSI device from being deteriorated and to enhance a yield rate by a method wherein the surface of Si or a compound semiconductor is treated in an atmosphere of a high-purity inert gas without coming into contact with the air or a treatment liquid contaminated with the air. CONSTITUTION:A semiconductor substrate 8 is immersed in an etching liquid which has been filled in a treatment tank 9 inside an oxide-film removal process area 1 and which is composed of an aqueous solution of hydrofluoric acid at room temperature; an oxide film in one part or in the whole on the surface of the substrate is removed. Then, the semiconductor substrate 8 is pulled up from the treatment tank 9 and is moved to a washing tank 10 which is situated inside an adjacent semiconductor cleaning process area 2 and which is filled with ultrapure wafer. During this movement operation, an exposed part on the surface of Si on the surface of the substrate 8 is hydrophobic but is in a state that its activity is high and that impurities are easy to be adsorbed. However, the substrate 8 is passed only through a high-purity inert gas 6 and does not come into contact with the air containing the impurities; as a result, the impurities are not adsorbed to the surface.
