Title: Starting-controlling method for automatic clutch
Inventor: HATSUTORI TOSHIHIRO
IPC: B60K23/02
Filed: 1982-05-06
Abstract: PURPOSE:To enable to smoothly control an automatic clutch, by preparing both a characteristic curve on the engaging side of a clutch and that on the disengaging side of the clutch. CONSTITUTION:In starting and accelerating, when the rotation speed (a) of the engine is raised N1, the rotation speed (a) and the degree of engagement of the clutch are selected in accordance with the solid line, the clutch is maintained in a half-clutched condition X1, and is operated at the position of point A. In this condition, when the rotation speed of the engine is lowered from N1 to N2, the engagement condition of the clutch is maintained as it is. When the rotation speed reaches N2, the operation is continued at the position of point B on the characteristic curve in dicated by the dotted line. When the rotational speed is lowered to below N2, the degree of half-clutched engagement is controlledly reduced along the dotted line. When a rotation speed N3 is reached, the rotation starts to be raised, but the degree of engagement is maintained at X2 until a rotation speed N4 is reached. From point D on, the degree of engagement is again calculated in accordance with the solid line, and the automatic clutch is smoothly controlled.

Title: Current sense amplifier circuit of semiconductor memory device
Inventor: CHIN SAIKUN
IPC: G11C7/06
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To enable sensing with high sensitivity even in an input signal of a minute level by a method wherein current bypasses which are conductively controlled corresponding to a voltage state of each output node are respectively provided with respect to each output node. SOLUTION: If input signals I1, I2 are small current signals, a voltage in output nodes N3, N4 is a voltage at a small level. At this point, by conductive control depending on an amplifier voltage level of the node N3 with respect to an NMOS transistor Q18, an output state of the node 3 is made a feedback to a node N2. Similarly, an output state of a node 4 is made a feedback to a node N1. As this result, a current difference between signals I1 and I2 is increased and an amplifier rate of output signals O1, O2 is increased. Thereby, it is possible to generate a stable sensing output even in a circuit having a low voltage, a small current signal and large input load capacity.

Title: Hydraulic circuit for improving operability in load sensing system
Inventor: IMAI HIROSHI
IPC: F15B13/04
Filed: 1991-03-15
Abstract: PURPOSE:To improve the operability of a hydraulic drive vehicle by preventing the effect that when, during the running of the hydraulic driven vehicle with a load sensing system, for instance a hydraulic excavating machine, its work machine is driven, a pressure compensating valve acts to distribute a flow rate according to the opening area ratio of the valve and the flow rate to a running motor decreases to greatly reduce the vehicle speed. CONSTITUTION:When the operating lever 17B of a work machine is operated during its running, pressure switches 20L, 20R, 20B severally send a detection signals to a controller 22, and an electromagnetic valve 26 is actuated by a command current issued from the controller 22 to change over a switching valve 23. A signal pressure PLS' acting on the pressure compensating valves 8L, 8R of directional control valves 3L, 3R to control running motors 2L, 2R is made smaller than a signal pressure PLS acting on a LS valve 5 by variable throttles 14a, 14b to increase a difference in a pressure before and behind the valves 3L, 3R. Thus a larger quantity of oil flows into the running motors 2L, 2R to prevent the lowering of a vehicle speed.

Title: Vane pump
Inventor: ASANO HIROAKI
IPC: F04C2/344
Filed: 1981-05-19
Abstract: PURPOSE:To reduce pulsation of pressure in a pump, by decreasing the degree of fluctuation of leakage by increasing the lower part of variation of leakage by the leakage of fluid caused by communication between a communicating groove of a pressure groove and a notch, and thereby minimizing variation of the discharge quantity of fluid due to internal leakage of pump. CONSTITUTION:When the discharge pressure of a pump is raised, pressure fluid is leaked from high-pressure side pressure grooves 37, 38 to low-pressure side suction ports 25, 26 through a side clearance formed between a pair of side plates 15, 16 and a rotor 22. A notch 40 of the rotor 22 is communicated with a communicating groove 41 of the pressure groove 37 at a substantially middle position of the angular range in which two sectors are fitted in the suction ports 25, 26, so that part of pressure fluid in the pressure groove 37 is leaked positively. Resultantly, lower part of leakage fluctuation is increased by the above leakage of pressure fluid, so that the degree of variation of leakage is reduced and fluctuation of discharge quantity due to internal leakage of pump can be minimized. Thus, it is enabled to reduce pulsation of pressure.

Then, the SiO2 diffusion mask 19 is removed by etching, and a P type ohmic electrode of Au-Zn is formed on the cap layer 18. Subsequently an Au-Ge N type ohmic electrode is formed on the surface of the N type InP substrate. Then, Cr and Au are vapor-deposited, and after a P type electrode 26 and an N type electrode 27 have been formed, they are formed into chips, thereby enabling to obtain a semiconductor laser.
