Title: Transmission device for belt
Inventor: KAWAI KOJI
IPC: A47J43/046
Filed: 1989-12-04
Abstract: PURPOSE:To mount a driven shaft vertically with regard to a reference mounting face of a chassis even of a chassis made of a thin metal plate with low rigidity by a method wherein a driving shaft is fit vertically to a reference fitting face of the chassis, while a driven shaft is mounted in the manner that it is installed slantingly with respect to a direction receding. CONSTITUTION:In a state where a belt 16 is not spanned on chassis 9, a face BC whereon a bearing 11 is to be installed,and a face AB whereon a motor 10 is to be installed, are not parallel with each other, and on account of this phenomenon, the faces AB and C are bent a little at the point B in the manner that a driven pulley 13 is installed so that it is mounted slantingly with respect to a direction recedingly from the driving pulley 15. However, when a tension that makes the driving pulley 15 and the driven pulley 13 approach with each other is applied between the two pulleys by spanning the belt 16 between said two pulleys, the chassis 9 deflects caused by the generated tension, and finally, the face BC whereon the deflecting bearing is mounted and the face AB whereon the motor 10 is mounted move in the manner that the two faces, i.e., BC and AB tend to become parallel or close to be parallel with each other. In other words, the slanting state of the driven shaft 12 in the state where the tension of the belt 16 does not exist is corrected by the deformation of the chassis 9 generated by the tension of the belt 16; resulting in making the attitude of the driven shaft 12 vertical with regard to the face AC whereon the chassis 9 is designed to be mounted.

Patent JP-S63168071-A (JP)
Title: Semiconductor laser
Inventor: SASAKI NOBUO
IPC: H01S5/00
Filed: 1986-12-29
Abstract: PURPOSE:To enable a small and light-weight device to successively change its oscillating frequency by a method wherein a reverse bias voltage is applied vertically to a multiple quantum well layer for a change in the energy between quantum levels in the quantum well. CONSTITUTION:A laser beam generated in a region (a) is projected upon a region (b) and, because of the optical pumping effect, carriers are injected into an intrinsic multiple quantum well MQW active layer 5. The injected carriers, owing to energy relaxation, are accumulated on the minimum quantum level. They are amplified because of the resonator feedback effect and stimulated emission, and then emitted from an emission surface in a laser beam 12. A reverse-bias voltage is applied to an N-electrode 1 of the region (b) at a terminal 10, which means the vertical application of the reverse-bias voltage to the active layer 5. This results in a shift in the quantum level energy, which causes a change in the oscillation wavelength corresponding to the reverse-bias voltage applied.
