Inventor: OZAKI HIROSHI
IPC: B29B11/16
Filed: 1984-02-09
Abstract: PURPOSE:To obtain the prepreg for a laminate capable of producing the laminate excellent in electric and mechanical properties by a method in which after the base material for a laminate has been kiss coated, included air is exhausted, and after the laminate has passed through the bath containing thermosetting resin varnish, the excess thermosetting resin varnish is removed. CONSTITUTION:The base material 1 for a laminate is set in the first bath containing thermosetting resin varnish 2 and is impregnated with thermosetting resin varnish 2, while passing a kiss roll 4. The thermosetting resin varnish 2 is pushed into the base material 1, and simultaneously the air included therein is exhausted, while passing said base material 1 on a squeezing roll 5. Next, the thermosetting resin varnish 2 is dipped again into the base material 1 for a laminate by the dip roll 7 placed in the second bath 6 containing the same thermosetting resin varnish 2 as the varnish in the first bath 3. Then, the excess thermosetting resin varnish is squeezed by a squeezing roll 8, and resin adhering amount is regulated.

Title: Cutting machine and method for cutting
Inventor: OKADA TAIJI
IPC: B27F1/08
Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To make it possible to suppress the increase in components and to further avoid the damage of a driver with excellent safety. SOLUTION: An elevator 2 is lowered in the direction of an arrow 90, and a timber 1 is cut by a cutter 60. A cover 7 is vertically movably held with the elevator 2, and normally disposed to cover the cutter 60. In this state, a switch SW1 detects an iron piece 40. When the cover 7 is brought into contact with the timber W1, the switch SW1 does not detect the piece 40, and the cutting depth is controlled with the position as a reference. In this case, since the cutter 60 starts rotating under the condition of detecting the switch SW1, when an operator lifts the cover 7, it can prevent the unintentional rotation of the cutter 60. Further, the movement of the elevator 2 is stopped based on the H signal similar to the output state (H) of the case that the detector for stopping position of the elevator 2 is wire disconnected.  Thus even if the disconnection occurs, the movement can be stopped.

IPC: H02P8/12
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To restrain the transient vibration of a rotor by keeping both ends of an non-excited winding in a multi-phase stepping motor in a short-circuit condition. SOLUTION: SW11 to SW15 opened from feeding point A to E are included in a circuit 10 which connects the feeding points with a common connecting point S. For windings A to D in a exciting step 1 condition, a conventional way is taken as follows: the feeding point E is connected to the common connecting point S through the SW12 to form a short-circuit phase out of a winding (e). The feeding point A is connected to the common connecting point S through the SW15 to form a short-circuit phase out of a winding (a). In the same way, a stage rises up to a step 10, and a step 1 is then taken. The excited winding is left as it is, the non-excited winding is kept in a short-circuit condition, and in any exciting step, a set of short-circuit phase is always formed, therefore the vibration of a rotor can be restrained.  On the motor side, only one wire of the common connecting point S may be added.
