Title: Belt drive device
Inventor: ETO SHINJI
IPC: F16H7/02
Filed: 1990-10-26
Abstract: PURPOSE:To provide a rotary motion of high accuracy without using a highly accurte expensive prime mover by arranging an intermediate pulley having an eccentricity so that the nonuniformity in the rotation of a drive wheel and the nonuniformity in the rotation due to the eccentricity of the intermediate pulley are reverse in phase to each other. CONSTITUTION:An intermediate pulley 6 is provided for driving an idler without load or a load not requiring accuracy of nonuniformity in rotation, constituted to have an intentional eccentricity, and installed having the pitch circle diameter rotating at the same frequency with that of the main frequency component of the nonuniformity in the rotation of a drive wheel 1 and with its phase reverse to the phase of the drive wheel 1. By making the pitch circle diameter of the drive wheel 1 same as that of the intermediate pulley 6, nonuniformity in the rotation of the drive wheel 1 is absorbed. As a result, the nonuniformity in the rotation of the drive wheel 1 is lessened and absorbed to transmit an accurate rotation to a driven wheel 4.

Title: Electromagnetic relay
Inventor: IDE TATSUMI
IPC: H01H50/04
Filed: 1989-11-06
Abstract: PURPOSE:To reduce the generated noise after mounting by shielding the vibration transfer energy and internal radiation noise generated by an electromagnetic relay block with a buffer spring member. CONSTITUTION:The energy generated by an electromagnetic relay block 1, e.g. the mechanical vibration energy transferred from a guide terminal 10, is transferred to a hole 11A, but the signal is extremely attenuated by the buffer spring member 2 of a thin plate constituting the vicinity of the hole 11A before it is transferred to an external terminal 12. The vibration energy consumed by the buffer spring member 2 is rarely transferred to a thin plate insulating member 8 and an insulating member 9, thus the bottom face of the electromagnetic relay block 1 and the upper face of the thin plate insulating member 8, and the lower face of the insulating member 9 and the upper face of an insulator 3 can be mounted and sealed in the contact state. The consumption of the contact is suppressed, and an electromagnetic relay with silencing function can be obtained.

Title: Input device
Inventor: IKEGAMI MINORU
IPC: G06F3/03
Filed: 1985-12-23
Abstract: PURPOSE:To widen an effective range where the position of a push point can be detected with high accuracy by reducing the surface resistance produced at a part where a pair of parallel electrode terminals cross with each other on a substrate to smaller than the surface resistance of the parallel electrode terminals. CONSTITUTION:An electrode 2 is formed on a substrate 4 together with an electrode terminal 1 having the surface resistance smaller than that of the electrode 2. While an electrode 6 is formed on another substrate 7. Both substrates 4 and 7 are bond with each other via a spacer 8 and plural convex spacers 9 so that both electrodes 2 and 6 are set opposite to each other. Thus an input device is obtained. Then the 2nd electrode terminal 5 is provided at a point where both terminals 1 in the X and Y directions cross each other. The surface resistance of the element 5 is reduced to smaller than that of the terminal 1. Thus the potential is fixed on both lines A and B and therefore a pushed position can be detected with high accuracy.

Title: Arithmetic error correction method for digital filter
Inventor: IIDA MASAO
IPC: H03H17/02
Filed: 1989-11-09
Abstract: PURPOSE:To correct a round-off error of an arithmetic output by relieving the round-off error of definite word length calculation in a digital filter having a feedback loop, making the arithmetic output at the time of calculating 2's complement nearly equal to the real number calculation output of a floating decimal point. CONSTITUTION:An adder 34 adds a remote end input signal X(n) from an input terminal 10 and a preceding error correction DELTAX(n-1) stored in a register 33 and stores the sum in a power storage memory 25. Then a computing element obtains the power of the remote end input signal and stores the power to the power storage memory 25. A divider 26 obtains a reciprocal of the power. A multiplier 27 multiplies the reciprocal of the power and a residual echo signal E(n) from a subtractor 24. A multiplier 30 multiplies the output from the multiplier 27 and the power stored in the power storage memory 25. The resulting output PX is nearly equal to a value being the subtraction of a round-off error of a definite word length caused by the arithmetic processing of the divider 26 from the residual echo signal E(n).

Title: Semiconductor integrated circuit
Inventor: SAKAGAMI KENJI
IPC: G01R31/28
Filed: 1990-10-26
Abstract: PURPOSE:To prevent power consumption from increasing by providing a driving voltage supply line for ECL(Emitter Coupled Logic) input/output buffer for test and a driving voltage supply line for normal ECL input/output buffer independently, and supplying the same voltage to the driving voltage line for test when packaging is performed. CONSTITUTION:The driving voltage supply lines from which driving voltages driving ECL input buffers 61-6n, output buffers 81-8n, input buffers 261-26n for test, and output buffers 281-28n for test, respectively are supplied are provided separately on an LSI chip. In other words, the driving voltage supply lines 4a, 4b, 9a, 9b, 24a, 24b, 29a, and 29b are separated on the LSI chip, respectively. In an ordinary operation (after the packaging) except for a test, two voltages which drive the ECL input buffers 261-26n for test and the ECL output buffers 281-28n for test are set equally. Thereby, no current flows on the ECL input/ output buffer for test, which reduces wasteful power consumption.
