Title: Ion injection device
Inventor: AOKI MASAHIKO
IPC: H01J37/317
Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To make uniform high-current ion injection possible, by making an oblong ion beam advance straight and deflect by a wien filter, to radiate a specimen and a detector, and the scanning speed for the specimen is controlled according to an observation result of the uniformity and irradiation quantity by the detector to restrain a temperature rise. SOLUTION: By a wien filter 3, a slitlike (belt-like) ion beam 2, drawn by an ion source 1, is mass-separated into ion beam 4 and 5, advanced straight and deflected to be outputted. The beam 4 passes through the slender hole 7 of a slit 6 to be radiated to a specimen 9 on a placing mount 8, and current quantity is measured by a Faraday cup 11 for receiving the beam 5. By this measured result, the current and the uniformity in a lateral direction of the beam 4, entered into the specimen 9, is observed, and a scanning speed in the Y-direction of the mount 8 is controlled by a scanning mechanism, in accordance with this observation result. This can remove unnecessary ion injection of the specimen 9, to restrain a temperature rise, thereby performing high-current ion injection uniform in a lateral direction.

Title: 2:n remote monitor control system
Inventor: HINO NORIAKI
IPC: G08C25/00
Filed: 1980-04-15
Abstract: PURPOSE:To always ensure an operation of system in the optimum mode, by exchanging information on the operation mode and the address of a slave station under polling between the two master stations via a signal lines and thus securing a backup between these two master stations. CONSTITUTION:The control command signal, which connects only the circuit 37 of slave station 38 to which the master station 30 gives a polling to the side of own system, is delivered to the circuit switch circuit 36 from the control part 33. Thus only the 1st and 3rd change-over switch 41 is switched to the side of station 30. Both master stations 30 and 31 always exchange information to each other via the signal line 32, and thus the master station 31 can give a polling to the slave stations other than those to which the master station 30 gives a polling. In case the station 30 becomes faulty, a signal is sent to all signal lines 42 from the control part 33. Then the signal 0 is sent to the signal line, and all output signals of the gate 44 are turned to 1. Each circuit 37 is connected to the signal line 40 of the station 31. Thus the station 31 backs up the station 30.

Title: Preservation box using dimming window
Inventor: OZAWA TETSUO
IPC: F25D23/02
Filed: 1992-03-05
Abstract: PURPOSE:To limit energy such as power upon opening/closing of a door of a preservation box to a minimum limit by providing a dimming window using a dimming material containing a liquid crystal substance and polymer to control transmitting, scattering of a light due to presence or absence of application of an electric field and a switching mechanism for controlling it. CONSTITUTION:A dimming window 4 uses a dimming material containing liquid crystal substance and polymer to control transmitting, scattering of a light due to presence or absence of application of an electric field. A dimming window 4 is mounted at a door 7, and is normally opaque in a state that a switch 5 is opened, but becomes transparent when the switch 5 is closed in the case of confirming presence/absence of its content. The window 4 can be, for example, mounted at doors 6, 8. The dimming window part of the door is desirably formed in a structure in which no article is contained or a small amount of article is contained in such a manner that the interior of a preservation box can be observed from the window 4. Thus, since a state of the article in the box can be confirmed without opening/closing the door, energy such as power for maintaining a temperature in the box can be minimized.

Title: Method of removing and repairing midsection of kiln
Inventor: NANBU MASAO
IPC: F27D1/16
Filed: 1988-03-03
Abstract: PURPOSE:To allow a repair work to be safely performed by preventing the fire-resistant material from falling and the joints from loosening by starting the repair work of a damaged area only after the adhesive has hardened which was forced into adhesive press-fit holes drilled in the fire resistant material around the damaged area. CONSTITUTION:The surface of joints around a damaged area 3 is covered with sealer, and adhesive press-fit holes 4 are drilled in the vertical and horizontal joints where epoxy resin as the adhesive is forced in under pressure. Since the periphery around the damaged area 3 is hardened like a picture frame once the adhesive is hardened, the fire resistant material 1 can be removed without causing the loosening of the surrounding area or the falling of the fire resistant material. The insertion of fire resistant material can be performed soon thereafter to complete the repair of the damaged area 3. By forming a strong monolithic structure around the damaged area 3 in this manner, the falling of the remaining fire resistant material and the loosening of its joints can be prevented, thus allowing the repair work to be performed safely with less cost in a shorter period.
