Filed: 1980-03-21
Abstract: PURPOSE:To make it possible to make certain of a quick feed direction and obtain a reproduced picture with high quality, by executing a forward reproduction or a backward reproduction to a medium, at the time of quick feed reproduction of a disk information recording medium. CONSTITUTION:Among signals which have been output from the disk 1 by means of a reproduction stylus 2, a main information signal is supplied to the demodulating circuit 4, and tracking signals fP3, fP2, fP1 are supplied to the BPF's 5-7, respectively. An error signal is formed 15 by use of each tracking signal, and tracking deviation of the reproduction stylus 2 is corrected. And, at the time of forward reproduction, the reproduction stylus 2 is forcibly shifted by one track portion in the inside circumferential direction whenever the vertical blanking periods (a)-(d) on the disk 1 are reproduced, and its scanning locus becomes a full line shown in the figure A, also at the time of backward reproduction, the reproduction stylus 2 is kicked in the outside circumferential direction, and its scanning locus becomes a full line shown in the figure B. As a result, since a part of each track is reproduced without fail, a picture consisting of perfect information can be obtained, and the reproduction direction can also be discriminated.

Title: Bar code reader
Inventor: TAKAYAMA YOSHIHIRO
IPC: G06K7/10
Filed: 1994-03-07
Abstract: PURPOSE:To prevent a misread due to a bit shift and a misread due to a wrong combination of two-stage bar codes by inhibiting both read half segments from being combined-when at least one of comparing means detect a discrepancy between character codes. CONSTITUTION:The recognition result of a decoder 7 is sent to a label discrimination part 8, which discriminates a bar code label. The bar code label discrimination result of the label discrimination part 8 is inputted as decoded data to a microprocessor 100 and stored in a RAM 102. The microprocessor 100 takes various tests of the discrimination results of the bar code label stored in the RAM 102 on the basis of program data in a ROM 101 to judge whether or not label discrimination is proper. When it is judged that the label discrimination result is correct, it is transferred to a host device through an interface I/F. Consequently, when a misread due to a bit shift is made, the comparison result indicates a discrepancy and the data are rejected, thereby securely preventing the misread.

IPC: B22D11/06
Filed: 1989-02-17
Abstract: PURPOSE:To secure air gap having stable thickness by pouring molten metal into pouring basin between two rolls mutually rotating in reverse direction and forming shape of the roll for producing a cast strip to the regular (n) polygon and specifying the range of diameter in circumscribing circle. CONSTITUTION:The shape of the roll has the regular (n) polygon, and at the time of using Dmm for the diameter in the circumscribing circle, (n) is made to be in the range of 0.005 - 0.100mm for D/4(pi/n)<2>. The considerable temp. difference between meniscus part 6 and the narrowest point 7 of the roll gap is generated in the solidified shell 2, and heat shrinkage develops between the positions 6 and 7. By this heat shrinkage, d1 and c1 points are shifted to d2 and c2 points, respectively and the air gaps 8, 9 are formed between the solidified shell 2 and the polygonal roll 1. By this air gap 8, the solidified shell is forcedly, periodically and slowly cooled. As the roll has polygonal shape, the solidified shell is heat-shrunk and slid on the corner (b) of the polygon and the air gap is forcedly and periodically formed. By this method, there is no fear of blinding, wear, etc., on the surface of the roll and the air gap always having stable thickness can be secured.

Title: Method for controlling shape of rolling mill
Inventor: HOSHINO MASASHI
IPC: B21B37/00
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To extend the range of shape control substantially by adjusting the axial position of an intermediate roll in the direction to negate the shape change due to excess reduction when the rolling reduction of any of the split type backing bearings exceeds the range of shape control while rolling by a multipul roll mill. SOLUTION: When, while rolling, either of No.1 to No.4 or No.4 to No.7 of the supporting units (AS-U) 6 of backing bearings 5 exceeds the upper limit in reduction or the upper limit in releasing, based on a prearranged selection table of an intermediate roll, which of the upper and lower rolls No.1, No.2, 2, 3 is to be shifted or which direction of shift is to be taken is decided. Then, the amount of modification of rolling reduction of each of the backing bearing supporting units 6 required for negating the amount of shape charge of a rolling mill in the case of shift of an intermediate roll is decided by a prearranged pattern of negating motion. Based on this value, by operating the lateral adjusting mechanism of a No.1 intermediate shaft, either of the required No.1 and No.2 intermediate rolls 2, 3 is shifted.

Title: Paralle design management system
Inventor: TABUCHI ATSUSHI
IPC: G06Q50/04
Filed: 1995-02-24
Abstract: PURPOSE: To smooth a process for performing review among related operators and deciding intentions for the change of design data requested by a certain operator at the time of advancing parallel design. CONSTITUTION: The operator converts the standard design data of a design object stored in a shared database into data expression intrinsic to a design data editing means 002 by a design data expression form conversion means 003 and edits them. When a review supporting system detects a change request for the standard design data, a communication control means constitutes a review message including the change request and delivers it to the other operators by a communication means. At the time, a change request informing means 004 decides the operators to whom delivery is to be performed and the timing of the delivery. Since the delivered review message is divided and stored for each change request part in a review history gathering means 006, the operator evaluates and selects the appropriate change request from it and reflects it on the design data.
