Filed: 1983-11-02
Abstract: PURPOSE:To obtain a titled device capable of correcting the variation of sheet thickness in sequence and removing the influence of the variation of inlet sheet-thickness, by detecting the variation of inlet sheet-thickness of a multiroll different-speed rolling mill at its inlet side and controlling a different-speed ratio between upper and lower work rolls in accordance with the advance of a material to be rolled at the time when a variation point of sheet thickness arrives at each roll gap. CONSTITUTION:A tracking device 9 is operated by a signal obtained by synchronizing a sheet-thickness deviation signal, detected by a X-ray thickness meter 16 provided to the inlet side of a mill, with the advance of a strip 21 outputted from a pulse oscillator 19 at the inlet side. A different-speed ratio between work rolls WR1, 2 is controlled in accordance with the variation of sheet thickness, from the time when a sheet-thickness variation point arrives at the 1st roll gap. This different-speed-ratio control is performed by speed-difference control devices 6a, 6b through speed control devices 5a, 5b of motors M1, M2 used for driving the rolls WR1, 2. Successively, respective correction controls at the 2nd and 3rd roll gaps are performed in the same manner; and a control, for preventing the generation of the variation of sheet-thickness of a product caused by the variation of sheet thickness at the inlet of mill, is performed.

Title: Two-way switch circuit
Inventor: HAMASATO KAZUO
IPC: H03K17/60
Filed: 1986-09-04
Abstract: PURPOSE:To electrically connect a switch and a drive circuit part, to easily make a switch element into ICs and to promote the drive efficiency by electrically driving interbases in two transistors, and closing the space between the one and other ends of a switch. CONSTITUTION:The bases of complementary transistors Trn and Trp are connected to the secondary side terminals s1 and s2 of a transformer T, and its primary side terminals p1 and p2 are connected to drive terminals I1 and I2. An AC signal is impressed between the terminals I1 and I2 to close the space between connection terminals O1 and O2 by a base current. A base current flows only in the half cycle of the AC signal. However, the transistor has the so-called accumulation time after a current flowing in the base comes to zero. Therefore, the switch can continuously maintain a closed state if the frequency of the AC signal is set at a full speed with respect to the accumulation time.

Title: Line pressure control device of automatic transmission
Inventor: NARITA YASUSHI
IPC: F16H61/06
Filed: 1988-08-23
Abstract: PURPOSE:To prevent generation of speed change shocks by restricting correction of the line pressure with a correction amount adjusted by study control during speed changing under the conditions different from the premise of target value for the inertia phase time. CONSTITUTION:A speed change gearing mechanism performs speed change by operating different friction elements selectively with the line pressure. During this period, a line pressure adjusting means makes study control of the correction amount so that the inertia phase time measured by a time measuring means according to signals from an input and an output rotary sensor will become the target value according to the type of speed change, and with this correction amount the line pressure during speed change is adjusted. When a different condition speed change signal output means emits a signal to indicate that the speed change to measure the inertia phase time is a speed change under different conditions from the premise for the target value, a correction yes/no judging means restricts correction of the line pressure and study control of the line pressure adjusting means. Thus generation of speed change shocks is precluded.

Title: Apparatus for inspecting liquid crystal display element
Inventor: MIYAMOTO ISAO
IPC: G02F1/13
Filed: 1996-07-19
Abstract: PROBLEM TO BE SOLVED: To improve inspection reliability by correctly detecting a shortcircuit of a liquid crystal display element with the use of an optimized measurement frequency. SOLUTION: An operation part 2 sets a low frequency of a signal to be input to a liquid crystal display element 1 and a reference value as a reference for detecting the presence/absence of a shortcircuit. A driving signal generation part 3 inputs the signal of the low frequency set at the operation part 2 to the liquid crystal display element 1 to be inspected. An impedance calculation part 4 calculates an impedance Z of the liquid crystal display element 1 when the signal is input. A comparison part 5 compares the calculated impedance Z with the reference value. If the calculated impedance Z is higher than the reference value, it is judged that the liquid crystal display element is not shortcircuited. If the calculated impedance Z is lower than the reference value, the liquid crystal display element 1 is judged to have a shortcircuit.
