Title: Lockup mechanism for automatic transmission
Inventor: UCHIDA TAKAYA
IPC: F16H45/02
Filed: 1991-03-30
Abstract: PURPOSE:To obtain a surely interrupted condition by forming a groove, annularly continued in a circumferential direction, on any of both pressure contact surfaces, in the case of a lockup mechanism having a flange and a piston, formed with the annular pressure contact surfaces opposed to each other, and interposing a clutch disk between both the pressure contact surfaces. CONSTITUTION:In this lockup mechanism, when oil of predetermined pressure is supplied into a pressure chamber 20 via an oil passage according to switching action of a control valve, a piston 16 is displaced to hold a facing 214 interposed between a piston side pressure contact surface 16a and a flange side pressure contact surface 6a. In this way, turning force of an engine is transmitted to a transmission through a flange 6, piston 16, clutch disk 23 and a shaft. Here in the flange side pressure contact surface 6a, a groove 31 of semicircular section is annularly formed in a circumferential direction to divide the flange side pressure contact surface 6a into two parts of internal/external peripheral sides by the groove 31. In this way, at the time of interrupting the lockup mechanism, pressure oil is allowed to easily flow between the pressure contact surface 6a and the clutch disk 23 to facilitate separation there between.

Inventor: AMANO TOMIAKI
IPC: B22C9/08
Filed: 1982-04-23
Abstract: PURPOSE:To provide a pipe of gating system made of metal which prevents the erosion effect and carburization phenomenon of the charging flow of molten metal by forming an Fe-Al alloy layer wherein the concn. and thickness of Al are specified on the inside surface side of a metallic pipe in contact with the molten metal.

When the alloy layer contacts with molten metal, said layer forms a thin dense film of Al2O3 on the surface thereof which protects the metallic pipe against the erosion of the molten metal. The metallurgical binding between the Al2O3 film and the Fe-Al alloy layer and between the alloy and the base of the metallic pipe is secure and there is no possibility of failure, etc. owing to thermal impact in the stage of casting. Such pipe of gating system is suited for a casting mold, etc.

Title: Constant torque device
Inventor: TAKITA MASAAKI
IPC: B41J33/16
Filed: 1987-03-23
Abstract: PURPOSE:To obtain a constant rotary torque without producing stick slip and prevent locking phenomenon under a high humidity condition by constituting with a friction plate made of cork mixed with rubber. CONSTITUTION:A ribbon feeding part 31 is fitted on a shaft 38, a friction plate 34 is bonded to the ribbon feeding part 31, a ribbon feeding part 33 with its tooth-shaped surface directed upward is fitted on the shaft 38, and the reverse surface of the tooth-shaped surface is made to be a contact surface which determines frictional force by contacting the friction plate 34. By using cork mixed with rubber as a material for the friction plate 34, the hardness of the friction plate 34 is made lower than that of cork. As a result, the coefficient of friction when being pressed is low and its variance is small to be able to obtain a constant rotary torque without producing stick slip. Air containing ratio compared with conventional material is also small and water suction rate is small. As a result, the increase in the thickness of the friction plate due to swelling by sucking water is also small. Therefore it is possible to prevent locking phenomenon under a condition of high humidity.

Title: Incoming circuit of telephone set
Inventor: NAKAYAMA YASUNOBU
IPC: H04M1/00
Filed: 1986-03-27
Abstract: PURPOSE:To prevent the flickering of incoming display and the momentary generation of a call tone while progressing miniaturization by providing a transistor switch circuit and a photocoupler turned on at the off-hook state. CONSTITUTION:the resistor 37 and capacitor 43 of a transistor (TR) switch circuit 8 form a delay circuit, the collector of the photodetector 40 of the photocoupler is connected to the input of the resistor 37 and the element 40 is turned on only at off-hook. After on-hook immediately after off-hook, the output signal of the photodetector 40 is led from a 0 potential to a potential decided by the voltage of a line 22 and resistors 35,36, but the potential is delayed by a prescribed time by the resistor 37 and the capacitor 43 and inputted to the base of a TR 34. Thus, the TRs 33,34 are not immediately turned on even at on-hook so as to prevent the flickering of incoming display or momentary generation of a call tone. Since the hook switch contact for exclusive use of the incoming circuit is not required, the telephone set is miniaturized.
