Title: Pulling up of crystal substance and apparatus for pulling thereof
Inventor: HIRAISHI YOSHINOBU
IPC: C30B15/20
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To enable the accurate setting of an interval between a melt and a member in a furnace and even the response to pulling up control by measuring the weight and prevent a bad influence of a measuring instrument on the pulling by measuring the interval of the member in the furnace and the melt by contact of an electrode attached to the member in the furnace and the melt. SOLUTION: This apparatus for pulling is equipped with a crucible 6 housing a silicon melt 7 therein, a seed crystal holding member 2 for holding a seed crystal 2, a radiation screen 5 as a member in the furnace for shielding the heat from a heating apparatus, an electrode 1 installed at the lower end of the radiation screen 5 and a voltage measuring device 3 in conduction with the seed crystal 2. The electrode 1 is formed of the same silicon as the crystal substance to be pulled up and a circuit of the voltage measuring device 3 is formed by bringing the electrode 1 into contact with the silicone melt 7 when the interval between the radiation screen 5 and the silicon melt 7 is a desired one. At this time, the seed crystal 2 is lifted to start the pulling of the crystal substance. The pulling is subsequently controlled by a weight measuring method or an image processing method.

Title: Carrier confinement structure based on double barrier structures
Inventor: ISSHIKI FUMIO
IPC: H01S5/026
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To realize good quality of carrier confinement structure which can correspond to a conventional separation confinement hetero structure, combine thin distortion layers to prevent deterioration of crystallization. SOLUTION: Two double barrier structures (or triple barrier structures) are disposed on both sides of an active layer 5 as sandwiched therebetween. By utilizing the fact that carriers are reflected by the double barrier structures, the carriers are confined between the two double barrier structures. At this time, quantum level is also established even between the two double barrier structures. In order to secure an energy difference necessary for the confinement, an interval between the two pairs of double barrier structures is set to be larger than a spacing 11 between each pair. Since a distortion layer is limited to only the barrier layers 6 and active layer 5, crystallization deterioration can be minimized.

Title: Information retrieving deive
Inventor: IMAI RYOICHI
IPC: G06F17/30
Filed: 1989-06-27
Abstract: PURPOSE:To retrieve information always exactly by permitting an electrification- shielding means to shield against electrification charges generated on a microfilm and photosensor which detects a mark. CONSTITUTION:When the microfilm F (information recording medium) is rewound at a high speed, there is a case where static electricity is generated in a place shown by an arrow D because the superimposed film F is caused to be separated. When charges are generated on the film F, electric force lines generated between charges are absorbed by a conductive member (electrification- shielding means) 21 to be led to the ground via a grounding means 25. Therefore, the light receiving part of the photosensor 17 is not affected by the electric force lines at all. Even if positive charges are generated on the film F, a shield against the photosensor 17 is provided by the conductive member 21; therefore, negative charges are not induced. Thus, information is always exactly retrieved.
