Title: Humid type frictional member and humid type frictional engagement device for speed change gear
Inventor: ISHIKAWA KEIICHI
IPC: F16H63/30
Filed: 1988-06-13
Abstract: PURPOSE:To reduce the speed change shock by forming an oil groove at the boundary parts of the frictional members where the first frictional member at the rear part and the second frictional member at the front part for one of the sliding direction in the normal and reverse directions are positioned. CONSTITUTION:0A frictional member 13 is shifted in the reverse direction to one sliding direction for an opponent member 17, and in pressurization, a portion of the oil which flows rearward from a front oil groove 16 is pushed outwardly, and another portion flows inside the second frictional member 152 which can be easily impregnated with oil, and the rest flows on the first frictional member 151 (hardly impregnated with oil). Therefore, an oil film on the frictional member 151 is easily broken, and the resistance for the pressurization is reduced, and the member 17 speedily contacts the frictional members 151 and 152, and a large engagement force is obtained from the primary stage of pressurization. When the frictional member 13 shifts in one sliding direction for the member 17, the oil film on the frictional member 15 in pressurization is hardly broken on the contrary, and the resistance is large, and the engagement force does not increase,and the engagement force is increased, keeping the prescribed delay up to the breakage of the oil film. Therefore, smooth shift-down is permitted.

Abstract: PROBLEM TO BE SOLVED: To restrain an increase in rotational speed, upon the interruption of a load, and properly maintain the strength and safety of a rotating part by adjusting the closing speed of a guide vane so as to correspond to a condition for water pressure and a load in a casing. SOLUTION: A speed setting unit 10 performs a subtraction process regarding an output signal and a signal detected with a speed detector, and a PID commuting element 14 receives a signal for a deviation from the output signal ▵p of a steady state speed drop rate outputting element 18, thereby outputting a proper servo motor opening degree instruction value. Also. water pressure in a casing downstream of an inlet valve is detected and the value of the water pressure is inputted to an output control characteristic computing element 40, together with an output from an opening degree detector 28. Thereafter, output calculated with the output control characteristic computing element 40 is inputted to an opening degree adjusting element 20.  At the same time, adjustment is made so that the closing speed of the guide vane is kept high when a measured water pressure value is lower than a maximum water pressure value at the high pressure side. Thus, an increase in the rotational speed of a hydraulic turbine can be restrained at a low level.

Title: Method for uniformly hardening thermally sprayed ceramic layer
Inventor: NARA YORIOKI
IPC: C23C4/18
Filed: 1986-06-21
Abstract: PURPOSE:To form a thermally sprayed wear-resistant ceramic layer for the surfaces of machine parts which is uniform and dense and is highly resistant to erosion wear by melting the sprayed ceramic layer by a laser beam, etc., and removing the pores in the sprayed ceramic layer. CONSTITUTION:The thermally sprayed ceramic layer 2 consisting of Al2O3, ZrO2, Cr2O3, etc., is coated on the surface of a machine constituting member 1 consisting of iron, steel, stainless steel, aluminum, copper, etc. in order to improve the wear resistance thereof. Since the sprayed ceramic layer 2 has internally the pores 2' at 8-18% porosity, the layer is highly resistant to abrasive wear (frictional wear) but weakly resists erosion wear (collision wear). The sprayed ceramic layer 2 is remelted locally by a CO2 laser beam 3, etc., to annihilate the pores 2' in air, or according to the kind of the sprayed ceramics, in an inert gaseous atmosphere; thereafter, the sprayed ceramic layer is slowly cooled to solidify again. Such treatment is executed over the entire surface of the sprayed ceramic layer 2 to form the reformed ceramic layer 7 having the excellent wear resistance to the erosion as well.

Title: Thin film transistor and fabrication thereof
Inventor: NAKAJIMA TAKESHI
IPC: H01L29/786
Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To prevent a required silicide at a silicide electrode part from being removed by covering an etching stopper with amorphous silicon on the end face side other than one end face and the opposite end face of an etching stopper. SOLUTION: Since an end face 9 of an amorphous silicon 3 is covered with an etching stopper 2, the end face 9 of an n-type amorphous silicon 3a does not touch a metal film of chromium, for example, at the time of deposition thereof. Consequently, no silicide is deposited on the end face of the n-type amorphous silicon 3a. Since it is not required to remove silicide after forming a source electrode 4 and a drain electrode 5, a silicide electrode 6 can be formed surely. Furthermore, since no silicide is left on the end face 9, leak current of a TFT can be suppressed and the characteristics of a display mounting the TFT can be improved.

Title: Light reflection measuring method
Inventor: TSUJI YUKITSUGU
IPC: G01M11/00
Filed: 1995-06-12
Abstract: PURPOSE: To make it possible to perform the measurement over a long distance with no limitation by the coherent distance of a light source by setting a specific relationship among the optical frequency sweep rate of light source, the distance resolution, the spectral width of receiving beat signal and the group velocity of light. CONSTITUTION: The coherent distance Lc of a semiconductor laser light source 11 having line width of Δν=500kHz can be determined to be about 64m according to a formula Δν=V/2πLc, where V is the group speed of light. Output frequency of the light source 11 is swept by the output control from an injection current sweep power supply 12. Assuming the band width of receiving system is ΔB=10MHz, an objective optical fiber 14 can be measured over about 100km when the position of Fresnel reflection point is measured at the farthermost output end Q of the fiber 14 with a distance resolution of ΔZ 100m. The optical frequency sweep rate is then set γ=10Hz/s according to a formula γ=V.ΔA/2ΔZ while taking account of the group velocity V of about 2×10<8> m/s in order to carry out the measurement with a desired distance resolution.  It can be realized by setting a maximum frequency sweep width ΔF=100GHz of light source 11 and a sweep time T=10ms. Consequently, the measurement can be carried out over a distance 3000 times as long as the coherent distance Lc.
