Title: Method for deciding rolled thickness of thick plate
Inventor: KUTOGI YUKIHARU
IPC: B21B37/00
Filed: 1991-09-12
Abstract: PURPOSE:To reduce the incomformity of thickness by requiring and correcting the transformation of the aimed crown through a specified expression when the weight of a slab is measured before the start of rolling and the weight of the measured slab is lighter than the weight of the target slab. CONSTITUTION:After the weight of the slab 3 is measured by a weight measuring instrument 7, it is compared with an estimated slab weight, a new amount of the aimed crown is decided, then, a rough rolling is carried out, the aimed crown is secured by a finish rolling mill 2 to make a rolled article 4. The measured value T2 of the slab weight before rolling is compared with the estimated weight T1 and when T1 is smaller, rolling is carried out according to schedule. When the measured weight value T2 is smaller, the aimed crown is changed. When the article length L1, the article width W1, the density rho are given, the transformation DELTACr of the aimed crown is required by DELTACn =F (T1, T2,5, L2, W1) and corrected in advance. In this way, after the slab weight is measured, the aimed crown is changed and a thick plate is rolled, consequently, the inconformity of thickness can be reduced.

Title: Automatic notifying equipment
Inventor: YAGI HIROSHI
IPC: G08B25/08
Filed: 1990-09-28
Abstract: PURPOSE:To easily implement setting, revision and confirmation of a data of a transmitter by allowing a receiver to receive a command of setting, revision and confirmation of the data of the transmitter externally and to send its command input to the transmitter. CONSTITUTION:When a supervisor resident at a receiver 10 sets, revises or confirms a data of a transmitter 4, the command is inputted to a CPU 36 via an input circuit 40. The CPU 36 discriminates whether or not the command represents data setting revision, and makes transmission control of the setting revision command when the command is the setting revision and gives a command to the transmitter 4. Moreover, when the command is not the data setting/ revision command, the CPU discriminates it as to whether it is a confirmation command, and in the case of the confirmation command, the transmission control of the confirmation command is implemented and the confirmation command is given to the transmitter 4. The transmitter 4 implements the processing of setting/revision or the transmission of a confirmation data according to the command. Thus, the receiver side makes data setting/revision/confirmation without the supervisor visiting to the transmitter.

IPC: H05K9/00
Filed: 1995-10-09
Abstract: PURPOSE: To make heat radiation to outside of an electronic part efficient by stacking a sheet consisting of a heat radiative material with a large heat radiation factor and a sheet consisting of heat radiative material with a large heat conductivity. CONSTITUTION: A heat sink 5 is constituted by stacking a heat radiative sheet 5a, a heat radiative sheet 5b, and a heat conductive sheet 5c in order on the topside of the electronic part 11 on a substrate 13. When the heat radiative sheet 5b receives the heat generated from the heat generator of the electronic part 11, it converts the heat into electromagnetic waves (mainly infrared rays) quickly and radiates it to outside. When the heat conductive sheets 5a and 5c receive the heat generated from the heat generator, they conduct the heat quickly to the sheets 5a and 5c. Stacking these two kinds of sheets 5a, 5b, and 5c will conduct the heat that the heat radiative sheet 5b could not fully radiate, to the heat conductive sheets 5a and 5c, so the heat radiation is performed efficiently. Hereby the heat radiation to outside of the electronic parts 11 can be performed efficiently.

Filed: 1986-11-04
Abstract: PURPOSE:To shorten the time required in cooling and to reduce noise by omitting a cold filter, by applying a dielectric material to the surface of a Dewar window by vapor deposition to form a filter. CONSTITUTION:A dielectric material is applied to at least one of the inner and outer surfaces of a spherical Dewar window 10 by vapor deposition to form a filter 11. Further, a quantum type infrared ray detection element 3 is mounted on a substrate 12 so that the center of the curvature of the Dewar window 10 is positioned in the vicinity of the detection element 3. The infrared rays 7 to be measured pass through the Dewar window to be incident to the detection element 3 and the unnecessary wavelength region thereof is blocked and, therefore, the increase in noise is suppressed. Further, the image to the detection element 3 due to the reflection from the inner and outer surfaces of the Dewar window 10 is generated on the detection element 3 and the mount substrate 12 in the vicinity thereof. That is, only the unnecessary infrared rays 8 radiated from the detection element 3 and the substrate 12 are incident to the detection element 3 but, since the radiation quantity thereof is sufficiently little, the effect thereof is also small.
