Filed: 1984-05-10
Abstract: PURPOSE:To improve the accuracy in estimating the plastic coefft. of material by storing signals for the change in screw-down positions and signals for the change in rolling reaction during rolling and making calculation by using the result of the measurement of the sheet thickness on the outlet side as well as the stored signals and corresponding data. CONSTITUTION:Devices 1c-6c for detecting the rolling reaction and devices 1d- 6d for measuring the screw-down position are provided to rolling stands 1-6. A device 40 for detecting the sheet thickness is disposed on the outlet side of the final stand 6. The storage means 71 of an estimating device 7 stores the signals DELTAS1-DELTAS6 for the change in the screw down position and the signals DELTAF1-DELTAF6 for the change in the rolling reaction of each stand during rolling. An estimating means 72 makes calculation by using the result of the measurement of the sheet thickness on the outlet side as well as the various stored signals and corresponding data. The mill spring constant and plastic coefft. of the entire stand are estimated with the simple arithmetic processing with good accuracy by the above-mentioned method.

Title: Variable gain amplifier circuit
Inventor: KAWAMURA TSUTOMU
IPC: H03G1/04
Filed: 1994-04-28
Abstract: PURPOSE:To prevent the functions of input/output coupling circuits and a neutralization circuit from being impaired by changing and controlling the impedances of the input and output coupling circuits and the neutralization circuit accompanying the control of a power supply voltage to a transistor element. CONSTITUTION:When a switch SW1 is turned on or off and the power supply voltage VE 1 to the collector of a transistor TR1 is changed so as to control amplification gain, the collector capacitance of the transistor TR1 is changed. The switches SW2-SW4 are turned on or off in synchronism with the SW1 so as to compensate the change of the collector capacitance. Thus, the impedances of the respective varactor diodes D1-D3 of the input/output coupling circuits M1 and M2 and the neutralization circuit N1 are changed. Respective constants and supply voltage values VE2-VE4 are set beforehand so as to make the respective impedances of the input/output coupling circuits M1 and M2 and the neutralization circuit N1 be optimum values corresponding to the change of the impedances of the diodes D1-D3.

IPC: H01L21/31
Filed: 1988-04-14
Abstract: PURPOSE:To make a uniform heating available for reducing the size of an equipment, by providing a heating element having a specified form at the lower part of a susceptor. CONSTITUTION:RF coils 8 are established outside of a quartz glass-made bell jar 2. A susceptor 11 which rotates while supporting a substrate 7 is heated by induction heating and a vapor growth of the substrate 7 is conducted in an introduced gas. On the lower part of this susceptor 11, a heating element 12 is established: The heating element 12 is larger in diameter than the susceptor and its central portion contacts the susceptor 11. The heating element 12 is heated together with the susceptor 11 by the coils 8.

Title: Spatial light modulation element and hologram image recording device using same
Inventor: KASASUMI KENICHI
IPC: G02F1/13
Filed: 1990-04-06
Abstract: PURPOSE:To obtain modulated light which has a high extinction ratio by inter posing a high-performance polarizing element, which has small effective area irrelevantly to the transmission area of a spatial light modulation element (SLM) and is finely adjustable by rotation, in the optical path of incident light. CONSTITUTION:Instead of providing a polarizing plate 2 in front of the liquid crystal SLM, the polarizing element 40 which can finely be adjusted by rotation is inserted into the incident light optical path. Consequently, the polarizing plate 2 has no sticking error and the polarizing direction of the incident light can be adjusted with the wavelength of the incident light. Further, the polarizing element is interposed in front of a collimation optical system, so the diameter of the transmission area may be several mm at most and a polarizing element 40 which has high transmissivity and a high unnecessary polarized light component suppression ratio like a Glan-Thompson prism is usable. Consequently, the SLM which has a higher contrast ratio than before is obtained.

Abstract: PURPOSE: To write all video signals on the small screen into the memory by reading out the rear edge of the corresponding filed after reading the tip part of the next field.  
     CONSTITUTION: The small-screen signal SB is written via signal WTE, and signals SB covering up to the terminal excepting start edge f 11  of field f 1  through start end f 21  of field f 2  excepting vertical flyback time V 2  are written into part A of a pair of memories in period α; and signals SB are written into memory B in the same way regarding fields f 2  and f 3  plus period V 3  in period β each. Then field tip f 21  is put before rear edge f 12  of field f 1  during period β-C when signal SB is read out from memory A, and then tip f 21  and read end f 12  are read out in section C and when memory A is read. In the same way, tip f 31  and rear end f 22  are read out. Thus small-screen signal SB is memorized, and then the information is replaced or the address is altered in order to secure memorization of whole signal SB. As a result, the break of the title and the like never occur at the circumference of the small screen.

Abstract: PURPOSE: To maximize the yield of high grade steel in forging process by removing the lagging  material and heat insulating material of the molten metal surface on the surface of the molten  metal poured into a mold mounted with the heat insulating material on the inside wall in the upper part then press-welding the low grade steel made gripping member with a projecting part and  spike members to the half-frozen molten metal surface.   
     CONSTITUTION: High grade steel molten metal 3 is poured into a mold 1 which is mounted with  a ring-form heat insulating material 2 on the inside wall in the upper part thereof. The surface of  the molten metal is insulated by lagging material 4. When the molten metal 3 is left standing in  this state, it successively cools from the lower or peripheral wall part and the freezing in the part  right under the lagging material 4 becomes slowest. When the part right under the lagging material 4 assumes a half frozen state on a progression of the cooling and freezing in the lower part,  the heat insulating material 2 and the lagging material 4 are removed. A gripping member 5  formed by relatively low grade steel is press-welded to this upper part. Here, the member 5 is  provided with a projecting part 5a for making up the missing part A after removal of the heat insulating material 2 and spike parts 5b to be plunged into the half frozen molten metal surface and  therefore if the half frozen part cools and freezes, the cast ingot body and the member 5 are surely  joined and integrated.
