Inventor: NAKANO YUKIYOSHI
IPC: F01L9/10
Filed: 1983-06-29
Abstract: PURPOSE:To obtain engine uniform output over the entire range of engine rotational speed, by providing such an arrangement that a part of intake valves and a part of exhaust valves are rested in a low speed rotational speed range, all intake valves are operated while a part of exhaust valves is rested in a middle rotational speed range, and all intake and exhaust valves are operated in a high rotational speed range. CONSTITUTION:Upon low speed rotation (R.P.M. < n1) an intake air valve side hydrualic control valve 27 is deenergized so that hydraulic oil is returned into an oil pan through a return port 28. Accordingly, no hydraulic oil is fed to hydraulic cylinders 12, 12E so that pistons 14, 14E are held in their retracted condition. Therefore, rocker arms 9, 15 and rocker arms 9E, 15E are not coupled together, respectively, so that the rocker arms 9, 9E provided with seat surfaces which are made in contact with cams, are alone actuated, and one of a pair of intake valves and one of a pair of exhaust valves are rested. Upon high speed rotation (n2 <=R.P.M.) both intake valve side hydraulis control valve 27 and exhaust valve side hydraulic control valve 32 are energized so that hydraulic pressure is fed to the cylinders, and therefore, all rocker arms 9, 15, 9E, 15E are actuated so that all intake and exhaust valves are operated.

Title: Resistance welding method for steel material
Inventor: SAWADA TOYOAKI
IPC: B23K11/02
Filed: 1985-05-29
Abstract: PURPOSE:To prevent the generation of defect on welding zone by providing a jet nozzle toward the welding position and by performing the welding with feeding directly a combustible substance from the nozzle to the material under welding. CONSTITUTION:The resistance welding is performed by bringing respectively electrodes 2, 2' into contact with two sheets of steel plates 1, 1' and by applying a voltage between the electrodes 2, 2'. The combustible substance 5 of oil, etc. is then dropped by providing the jet nozzle 4 of the liquid combustible substance toward the lower part from the immediately above the welding position. Or by arranging two jet nozzle 10 of gaseous combustible substance at the lower part of the welding position the cumbustible gas of hydrogen gas, etc. is spouted.

Abstract: PURPOSE:To improve the communication efficiency by applying line polarity detection and call tone detection so as to save the line polarity when no incoming call exists thereby discriminating whether an incoming call exists or not, while preventing collision between incoming and outgoing calls and reducing the incoming call detection time. CONSTITUTION:A microprocessor 10 inputs a signal of lines L1, L2 to a polarity detection circuit 8 and a call tone detection circuit 9 at calling, the circuit 8 is lighted when the line L1 is positive and the circuit 9 is lighted after the signal of the lines L1, L2 is converted into a DC signal to send a call tone to the processor 10. When both the line polarity inversion and the call tone are not detected, the processor 10 discriminates it as absence of incoming call and saves the line polarity obtained by the circuit 8 in a memory 11. When the processor 10 discriminates the absence of incoming call, a dial is sent to the lines L1, L2 from a transmission circuit 2 and after the end of dial connection by a connection end circuit 6, the communication by a MODEM 4 is transited.

Title: Method and device for intermediately storing print, which isstacked in scalelike shape and reach
Inventor: YAKESU MEIYAA
IPC: B65H29/58
Filed: 1984-06-08
Abstract: An imbricated product subformation is formed from one half of the printed products delivered in an imbricated product formation by a conveyor or transporter. This subformation is guided through a deflection or turning device. The printed products are accelerated and separated or singled as they run through this deflection or turning device and are simultaneously inverted. After leaving the deflection or turning device, the printed products are conveyed against a fixed stop member and are then deposited upon a belt conveyor to form a new imbricated product subformation. A second subformation is formed from the other half of the arriving printed products and is deposited upon the first altered subformation and is then conjointly wound up with this first altered subformation to form a coil or wound product package. By dividing the initially arriving imbricated product formation into two subformations and subsequently reuniting these subformations, the winding operation can take place at a speed which is only half as great as the delivery speed of the initially arriving imbricated product formation.
