Title: Wide-band driving system for acoustooptic deflector
Inventor: NARAHARA TATSUYA
IPC: G11B7/085
Filed: 1988-06-17
Abstract: PURPOSE:To make the deflection efficient of output beam light invariably constant by controlling the output power of the output beam light corresponding to the frequency of an AC signal applied so as to vary the Bragg angle of the output beam light. CONSTITUTION:The deflection efficiency eta indicating the intensity of the output beam light deflected by the acoustooptic deflector 30 drops at f3 nearby the center frequency when the variation width of a frequency applied for wide-band driving is swept from f1 to f5. Then, an attenuator 43 is provided behind a variable frequency oscillator 42, and a power controller 45 gives this attenuator 43 a relatively high attenuation quantity H.dB for the frequencies f1 and f5 of relatively high deflection efficiency eta or a relatively attenuation quantity L.dB for the frequency f3 of low deflection efficiency eta. Consequently, a deflection output beam which has constant deflection efficiency even in a wide range is obtained.

Title: Belt conveyor
Inventor: IDA AKIHIRO
IPC: B65H7/02
Filed: 1992-05-15
Abstract: PURPOSE:To accurately detect the moving speed of a belt member also protect the belt member from being damaged by composing the circumferential surface of a speed detecting roll of a rigid body portion having a specified outside diameter and an elastic body portion having an outside diameter slightly larger than that of the rigid body portion. CONSTITUTION:This belt conveyor is equipped with a belt member, which is conveyed along a specified course, a speed detecting roll 2, which is in contact with the belt member and rotates in company with the belt member, and a moving speed detecting means which detects the moving speed of the belt member based on the rotation of the speed detecting roll 2. The circumferential surface of the speed detecting roll 2 is composed of rigid body portions 22a, 24 having specified outside diameters and an elastic body portion 23 having an outside diameter slightly larger than that of the rigid body portions 22a, 24. Thus because the high friction coefficient elastic body portion 23 makes necessarily contact with the belt surface, it prevents the two from slipping mutually even in the case when the strength of the contact pressure of the speed detecting roll 2 to the belt member is weak.

Abstract: PURPOSE:To quickly chase a parcel with the device of its own company even if the parcel has the code label of another company, by providing a means which discriminates whether the code of a parcel belongs to its own company or another company and a means for sticking the code label of its own company. CONSTITUTION:A parcel 4 with the code label of another company is read by a code reader 9 and, when it is discriminated that the code of the parcel 4 belongs to another company at a central computer 3, the code of its own company is newly put on the parcel with a means 20 for sticking the code label of its own company. In other words, the central computer 3 discriminates the code of a parcel whether it belongs to its own company or another company from the signals inputted from the code reader 9 and a code input key 10 and, when it is discriminated that code of the parcel belongs to its own company, the code is stored in a master file 18 as it is. When it is discriminated that the code belongs to another company, the code label of its own company is newly put on the parcel by means of the means 20 and both of the codes are stored in both of the master file 18 and a corresponding file 19. Therefore, the parcel can be processed smoothly, even when the parcel is inputted by using the code of its own company or the code of another company.
