Filed: 1984-06-18
Abstract: PURPOSE:To form the finer crystal grains of a weld metal and to improve the ductility and toughness thereof by oscillating a non-consumable electrode in the direction parallel with a weld line simultaneously with the operation for swiveling the non-consumable electrode. CONSTITUTION:The non-consumable electrode 3 is inserted into a narrow groove part 2 formed between a pair of base metals 1a and 1b and is moved from the right side toward the left side as the weld line to join a pair of the base metals 1a, 1b via the weld metal 4.

IPC: F16K15/00
Filed: 1980-09-05
Abstract: PURPOSE: To improve fatigue strength and abrasion resistance of a valve by increasing the surface hardness with nitride film formed on the valve surface through ionic nitrogenation.  
     CONSTITUTION: A suction valve 11 is made thin and formed on its surface with nitride film 13 which is made by ionic nitrogenation which implies heat treatment holding the valve in the atmosphere mixed wth nitrogen and hydrogen at the temperature of 480°CW500°C for 30min. By this method the suction valve 11 is made hard on its surface, while its fatigue strength and abrasion resistnce being improved, resulting in allowed smaller thickness. The smaller thickness prevents the delay of opening or closing of the valve of the compression element 2, resulting in its enhanced performance factor. The thinner plate form suction valve 11 may not be forced to fall down in the suction port 7 opened in the valve seat board 9 by its deformation, or to be bent due to abnormal high pressure caused by the piston 6 in the cylinder 5.

Title: Photomultiplier type cold cathode electron source
Inventor: HANE KUNIO
IPC: H01J1/34
Filed: 1993-04-30
Abstract: PURPOSE:To extend the life of a cathode-ray tube by constituting a photomultiplier type cold cathode electron source of a light emission element, a light emission element driving portion for driving the light emission element in response to an image signal, and a secondary electron multiplier. CONSTITUTION:When an image signal exceeds 0V the output voltage of a light emission element driving circuit 10 rises and a light emission element 20 generates a laser beam. The amount of emission of the element 20 is detected by a PIN type light emission diode 14 and fed back to the circuit 10 via a feedback signal amplifier circuit 12. The image signal and the feedback signal are always controlled to the same one so that the amount of emission of the element 20 is held constant. A channeltron is used as a channel type multiplier 32. When high voltages are applied to both ends of the channeltron, electrons impinging on the channeltron from a negative electrode travel along a positive electrode while colliding against the tube wall. The electrons then impart the energy obtained to the tube wall, from which secondary electrons are then released. The electrons newly generated cause electrons to be generated one after another, forming a so-called electron avalanche. The electrons are output to an electron gun 40.

Title: Control method for continuously variable transmission for vehicle
Inventor: ITOU HIROSHI
IPC: F16H9/00
Filed: 1983-07-11
Abstract: PURPOSE:To improve operation feeling and the efficiency of fuel comsumption during slow acceleration, by a method wherein, when slow acceleration is demanded, the speed ratio of a continuously variable transmission for vehicle is held at a constant value. CONSTITUTION:When slow acceleration is demanded, a speed ratio (e) of a continuously variable transmission for vehicle is held at a constant value. This causes increasing of a car speed V through only an increase in the output torque of an engine during slow acceleration. Thus, a rotation speed Ne of an engine is increased proportionally to the car speed V, and this prevents the occurrence of a trouble in which the rotation speed Ne of the engine is too high in proportion to an increase in the car speed V. Further, since the continuously variable transmission of the engine is stopped in its speed changing function during slow acceleration, the transmission loss of the continuously variable transmission for vehicle due to a speed change is prevented from being incurred during such stop, and the efficiency of fuel consumption is improved.
