Title: Data recording and reproducing method
Inventor: KAWAGUCHI BUNRO
IPC: G11B20/12
Filed: 1985-04-19
Abstract: PURPOSE:To shorten a data reproducing time by changing the direction of data array for each N rows (N: natural number of >=2) when data are recorded on an optical card in plural rows and then reproducing N rows of these data at a time. CONSTITUTION:When data are recorded in plural rows, the direction of data array is changed for each N rows. When these data are reproduced, N pieces of light beams are irradiated at the side of E of recording tracks 31-3N. Then an optical card 1 is shifted toward (a) for simultaneous reproduction of N rows of data. When the reproduction is through with tracks 31-3N, N pieces of beams are shifted toward (c) by N rows and irradiated to the side F of recording tracks 3N+1-32N. The card 1 is moved toward (b) for simultaneous reproduction of N rows of data up to the tracks 3N+1-32N. Thus the simultaneous reproduction of N rows of data is repeated to perform reproduction of data at a high speed with no idle feed.

Title: Redundancy circuit
Inventor: EDO YASUHIRO
IPC: G11C29/04
Filed: 1990-03-30
Abstract: PURPOSE:To cut a newly added fuse line and to select again the new word line of a redundancy circuit or the digit line of the redundancy circuit by connecting an N-type MOS transistor and the fuse line between the other end of a signal inversion circuit and a common connection point. CONSTITUTION:The potential of a contact A is held in a high level even if an address signal A0 is selected by cutting a fuse line F2, for example, by adjusting it to the address of a defective word line. The potential of a contact B comes to a low level by transistors (TR)1 and 2, a P-type MOS transistor TR3 comes to an on-state and the potential of the contact A is held in the high level as it is through a fuse line F1. If there, is a defect in the word line of the redundancy circuit which a discrimination circuit 10 selects, the fuse line F1 is cut. Thus, the contact A cannot be held in the high level, the contact B comes to the high level, TR4 is turned on and the contact A is held in the low level.

Abstract: PURPOSE: To automate conveyance by providing a trackless truck adapted to self-travel by feeding from a trolley rail with a control device for calculating a traveling distance and displacement, and calculating the azimuth of the truck from a difference between a trolley arm angle and a shoe angle. CONSTITUTION: A self-traveling conveying truck 20 in a small bore diameter section tunnel is provided with a control device for calculating the traveling direction position of a truck from the rotation amount of an axle, inputting the absolute value at fixed interval, eliminating a cumulative error by resetting and calculating a traveling distance.

Title: Method for estimating excitation position
Inventor: SAKATA MASAYOSHI
IPC: G01H17/00
Filed: 1989-04-04
Abstract: PURPOSE:To accurately estimate vibration by comparing the minimum response error corresponding to the excitation position with a minimum response error and estimating the point where the minimum response error is obtained as a real excitation position when the difference between the both is less than a specific value. CONSTITUTION:Assuming that an exciting force 3 operates on only one point, the current response error is calculated to predict the excitation point of the minimum value. Thus, when one excitation point of the exciting force 3 is clearly identified, it is assumed that the exciting force 3 operates on two points so as to find a next point; and the response error between a pair of the 1st found point and the other point is found repeatedly to find which pair has the minimum response error, and consequently the excitation point 2 when the exciting force 3 operates on two points is estimated. Thus, (n) response errors are compared to estimate the position where the response error becomes minimum as the real excitation position 2. Consequently, it is accurately predicted how a machine, etc., vibrates during its operation.
