Title: Control method for paper feed roller in automatic paper feed device
Inventor: ITO YOSHIHIRO
IPC: B65H7/18
Filed: 1986-01-27
Abstract: PURPOSE:To aim at preventing erroneous paper supply due to a slip of a paper feed roller on the surface of a paper sheet, by driving a paper feed roller, intermittently on a predetermined cycle. CONSTITUTION:A paper feed roller 9 abuts against and rolls on the upper surface of stacked paper sheets 18 which are therefore fed out and are separated from each other by means of a separating roller 8 and a friction pad 15. Further, a sheet detecting sensor 6 is arranged upstream of the separating roller 8. In this arrangement, the paper feed roller 9 is driven intermittently to repeat a set cycle including a rotation and a stop, and is controlled such that the drive of the paper feed roller 9 is terminated when the sheet sensor 6 delivers a detection signal. As a result, even though the paper feed roller 9 slips due to instant overloading, static friction is effected when the rotation of the subsequent intermittent drive is initiated, thereby it is possible to surely feed out the paper sheets 18.

Title: Semiconductor laser and its manufacture
Inventor: NAKATSUKA SHINICHI
IPC: H01S5/00
Filed: 1993-02-02
Abstract: PURPOSE:To prevent crystal defects by covering the edge plane of a semiconductor laser with a semiconductor layer which is formed of group II elements and group VI elements separately from the semiconductor crystal which forms the semiconductor laser element and permitting the thickness of the semiconductor film to be a quarter of the wavelength of the laser beams which the semiconductor laser element projects or less. CONSTITUTION:A semiconductor wafer is split in bar-shape at approximately 600mum intervals to be fixed with the split plane facing top and a ZnSe layer 12 is crystal-grown for approximately 10nm by introducing the wafer into a molecular-beam crystal growing device. Approximately 0-3% lattice unconformity is found between a ZnSe layer 12 and an AlGaAs, however, crystal defects are not generated since the film is thin. Then, the front edge plane of the element is coated with Al2O3 reflection preventing coating 13 and the rear edge plane is coated with highly reflecting coating 14 constituted of a-Si/Al2O3. The ZnSe layer allows less heat transmission compared with the AlGaAs layer and temperature increase at the edge plane is concerned, however, since the AnSe layer is very thin, heat is efficiently removed by Al2O3.

Title: Shielding container
Inventor: HAYASHI KATSUMI
IPC: G21F9/36
Filed: 1991-02-06
Abstract: PURPOSE:To lower the temperature of the inside of a shielding body, to moderate a temperature gradient of the inside and the outside and thereby to improve the soundness of the shielding body by a construction wherein a plurality of closed flow pipes extending in the direction of a tube are disposed in a shielding material and a coolant (water) is made to circulate therethrough. CONSTITUTION:A coolant piping 1 is installed along iron plates 3 on the outside and inside so that it surrounds a shielding material 2, and the upper and lower parts of the piping are joined so that a long loop-shaped pipeline is formed. The piping 1 thus prepared is disposed in a necessary number through the whole peripheral part. When water is filled up in the piping 1 beforehand, a water temperature is made to rise by the inside wall of a shielding container (high-temperature side) being heated, the water is cooled down and made to radiate heat by the outside wall and the temperature lowers. By the repetition of this movement, the temperature of the inside lowers gradually. By lessening a temperature difference between the inside and the outside of the shielding material 2 and moderating thereby a temperature gradient, besides, a crack of the shielding material 2 can be prevented. In addition, a neutron shielding effect by the water can be expected.
