Abstract: PURPOSE:To reduce the number of times of sliding a key board and improve the operability at the time of inputting by disposing a plural layers of key boards combined with each other to slide freely positioning the key board having menu keys for menus of a higher usage frequency at the uppermost layer in a surface of a main body case where a display is provided. CONSTITUTION:A key board having a number of keys, that is a menu key board 8 having a number of menu keys 7, is disposed at a lower part of a main body case 3. A menu key board 15 having a number of menu keys 14 is installed to slide freely over the menu key board 8 in the main body case 3. For the menu keys 14 in the menu key board 15 positioned at the upper layer, menus of a relatively higher usage frequency are selected. For the menu key board 8 positioned at the lower layer, a menu of a higher usage frequency is selected and set at an upper position. This is for a consideration that the opening quantity of the menu key board 8 in the upper layer need not be very large when the menu key board 15 at the lower layer is selected. The menu keys 7 can thus be selected with a small opening quantity, thereby the operability is improved.

Title: Two-phase dc commutatorless motor
Inventor: KISHIMOTO ISAO
IPC: H02K29/00
Filed: 1979-06-30
Abstract: PURPOSE:To reduce irregularity in the rotation torque of a rotor with a simple construction by mutually shifting the positions of magnetic neutral points between field magnetic poles and auxiliary field magnetic poles. CONSTITUTION:Respective field magnetic poles 10 and auxiliary field magnetic poles 12 assume mechanical angles pi/2 and pi/4, the centers of the magnetic poles 12 forming N-poles correspond to the magnetic neutral points of the magnetic poles, as a result of which the magnetic neutral points between the magnetic poles 12 are mutually shifted. In the magnetic pole 10 as well as the magnetic pole 12, the interlinkage magnetic flux density with respect to an armature coil 16 due to the magnetic pole 10 and that due to the magnetic pole 12 become 2:1. Accordingly, in a period of 0<=theta<=pi/2, and pi<=theta<=3pi/2 of a period where the rotor 6 makes one revolution, the rotary torque is generated by the first phase armature coil 16, and in other periods, it is generated by the second phase armature coil 16. The combined torque is greatly reduced in its pulsating ratio as compared with the rotation torque due to the interlinkage magnetic flux from the magnetic flux 10. By these procedure, irregularity in the rotation torque can be reduced.
