Abstract: PURPOSE:To facilitate the laminating work by matching the bore of a sector- shaped core to the outer diameter of a mandrel on a surface plate, matching the slot of a core to a guide key of the mandrel, laminating prescribed number of sheets, and then clamping them with a clamper and bolts. CONSTITUTION:A laminating jig is associated in advance with set mandrel 12, a core guide key 13, a surface plate 15 and a centering set pin 14. The bore of a stator sector-shaped cores 8 are matched to the outer diameter of the mandrel 12, and the slot formed on the cores 8 is matched to the key 13, and prescribed number of sheets are laminated. Then, when the mandrel 12 and the key 13 are moved upward to finish to laminate the specified number, the stator 8 is clamped fixed with clampers 1, 2 and a core bolt 7, a supporting rod 3 is inserted and welded. In this manner, a laminating frame can be eliminated, and the laminating work can be facilitated.

Patent JP-S5442320-A (JP)
Title: Surface quenching apparatus
Inventor: NAGAI HARUHIKO
IPC: C21D1/09
Filed: 1977-09-09
Abstract: PURPOSE:A uniform and deep quenching layer is obtained by scanning a material to be quenched with a laser beam having saw tooth wave form, which is composed from a laser beam deflected by a revolving polyhedral mirror. CONSTITUTION:A laser oscillator 1 generates a laser 7. A revolving pyramid-type n-hedral mirror 8 reflects the laser and produces a scanning light beam having rotational angle of 2pis/n. The beam thus formed impinges onto a parabolic mirror 4 and reflects. The reflected beam moves from a to b as the mirror 8 revolves. The moment the mirror 8 reaches to a rotational angle of 2pis/n, the laser rapidly moves from b to c, thus the scanning beam has a one-way tooth saw wave form, the very fast scanning on b-to-c-dotted-line substantially uniformalizes a residing time of scanning beam on the surface of the material 5 thereby producing deep uniform quenched layer on the material 5 to be quanched.

Abstract: PURPOSE:To process the document data produced by a low-function device incapable of the table processing with use of a high-function device capable of the table processing by extracting the ruled line information and defining this as a table area. CONSTITUTION:A high-function device capable of the table processing has a data structure where the in-table data are discriminated from the out-table data and therefore reads physically the volume label of a supplied floppy disk to discriminate a specific device type that produced the document data. Then a table area is extracted out of the ruled line information in case it is known that the document is produced by such a device that controls the ruled line information and the character information independently of each other and does not define these information as a table. The character information also includes the characters contained in the table and therefore each character is checked for its specific display position in the document. Thus the characters contained in the table area are defined as the table data having the coincidence with the data structure of the high-function device.

IPC: H04B3/04
Filed: 1988-05-02
Abstract: PURPOSE:To prevent the deterioration of the error rate of a signal in an equalization circuit by supervising the amplitude of an input signal in a level detection circuit and supplying information to a coefficient setting circuit when the level drops lower than a normal one so as to attain control in a control circuit. CONSTITUTION:The signal inputted to an input terminal 1 is inputted to a transversal filter 2, the coefficient setting circuit 3 and the level detection circuit 5. The level detection circuit 5 compares the levels by a threshold lower than the mean amplitude of the input signal. When the level of the input signal becomes smaller than the threshold, a level detection signal is outputted to the control circuit 6. It outputs a coefficient setting stop instruction to the coefficient setting circuit 3 by the level detection signal. The coefficient setting circuit 3 executes the holding action of a coefficient value by the coefficient setting stop instruction. Consequently, the automatic equalizing circuit with high stability can be realized by simple circuit constitution.
