Title: Valve system for internal combustion engine
Inventor: ARIGA KENJI
IPC: F01L3/10
Filed: 1998-07-10
Abstract: PROBLEM TO BE SOLVED: To eliminate initialization of a valve system for closing intake and exhaust valves in starting an engine by forming an energizing means on the opening valve side via a piston from an air spring for energizing a valve shaft using compressed air supplied to an air chamber, and by forming the energizing means on the closing valve side. SOLUTION: A means 7 for energizing a valve shaft 1a of a valve element 1 to the valve opening side is formed from an air spring, and a means 8 for energizing it to the valve closing side is formed from a coil spring. When each electromagnetic coil 5, 6 degausses magnetic field during engine stop, because inner pressure of an air chamber 13 in an air spring 7 becomes in an atmosphere condition due to air leakage from a seal portion and spring force of a coil spring 8 closes the valve element 1, initialization of a valve gear 2 that the electromagnetic coil 5 is temporarily excited in magnetic field to close the valve element 1 is eliminated. Therefore, consumed power in a battery can be saved. The air chamber 13 is provided with a relief valve 19, which keeps the inner pressure of the air chamber 13 at a desired pressure balancing with the spring force of the coil spring 8.

Title: Magnetic recording and reproducing device
Inventor: KONOSHIMA KAZUHIRO
IPC: G11B15/087
Filed: 1988-08-05
Abstract: PURPOSE:To automatically set a fast forwarding mode on a nonrecording part and to automatically set a reproducing mode on a recording part during a reproducing operation by detecting the presence of a control signal as a reference signal for a control circuit and outputting its result to an operation circuit. CONSTITUTION:The recording part of a magnetic tape 1 is necessarily written with the control signal as the reference signal for the control system circuit. Since this control signal is utilized for a discriminating signal of whether the magnetic tape 1 is the recording part or nonrecording part, this signal is inputted to a control signal presence/absence discriminating circuit 5, and by its detecting output, the operation circuit 6 is controlled. That is, when the control signal is absent during the reproducing time, the operation circuit 6 is controlled by the output of this control signal presence/absence discriminating circuit 5 so as to set the fast forwarding mode, and when the control signal is present again, it is controlled to set the usual reproducing model. Thus, when the control signal is absent during the reproducing time, the fast forwarding reproducing mode is automatically set up, and the nonrecording part is skipped over automatically.
