IPC: G06F3/048
Filed: 1987-05-29
Abstract: PURPOSE:To decrease the number of operation steps to start a program when plural documents are edited at one time by using three fields. CONSTITUTION:An icon control table 50 is prepared for each icon 32. The table 50 includes a field holding the start enable frequency, a field holding the programs under starting states, and a field showing an icon pointing state. When the start enable frequency is set at (n), '1' is added to the number of programs set under the starting states by a program start processing means against the icon designation frequency up to (n-1) number of times. Then the corresponding program is started. In the n-th icon pointing action, '1' is added to the number of programs under the starting states and a program starting means switches an icon designating state to a designation inhibiting state. Then an icon display changing means displays an icon designation inhibition state. Thus it is possible to unify the start instruction to a program that can be started in plural times and that to a program that can be started once only.

IPC: F16K31/40
Filed: 1983-07-18
Abstract: PURPOSE:To reduce action noises generated during operation by inserting by pressure and coupling a shock-absorbing spacer with the lower end section of a cap at the upper end of a tube slidably fitted with a plunger. CONSTITUTION:When the voltage is applied to a solenoid valve coil 21, a plunger 26 is sucked downward against the spring 32. Accordingly, a needle 30 blocks a valve port 29, and a valve plug 40 blocks the valve port 14 of a valve seat 12 by an action of the pressure difference. When the voltage to the solenoid valve coil 21 is cut off, a plunger assembly 17 is pushed upward until it hits a spacer 24 to open the valve port 14. In this case, a shock-absorbing material such as rubber or resin is used for the spacer 24, thereby shock noises for the cap 7 of the plunger assembly 17 can be reduced to a minimum.
