Title: Manufacture of laminated iron core
Inventor: ISHIKAWA TAKASHI
IPC: B21D28/02
Filed: 1980-12-15
Abstract: PURPOSE: To manufacture a highly accurate iron core by a small number of processes by blanking an iron core steel plate, and at the same time, fixing to a body using a device that gives little working strain while keeping accuracy of blanking by a special ring.  
     CONSTITUTION: A reference inner diameter part 1 is blanked from a hoop material 9 by a punch 10 and a die 11. Then, the inner diameter part 1 is positioned by an inner diameter pilot 12, and a prescribed number of slots are blanked radially. Next, it is formed to the final external form of the iron core steel plates 15 making the inner diameter pilot a standard. By this way, the iron core steel plates laminated in the die 11 are lined up accurately. Under this condition, a part between supporting rings 18 is pushed downward by blanking pressure of a punch 16, and a boundary space between outer circumference shearing face and rupture face of the iron core steel plate is discriminated by a sensor 20. Then, a laminated iron core is obtained by welding adjoining iron core steel plates using a laser welding machine 19.

Title: Input mode confirmation method
Inventor: SOGABE SAE
IPC: G06F3/023
Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To improve the operability for confirmation of an input mode by giving the stroke that is assigned to the mode set after the chance of the input mode to an input key after detecting the push of an input mode change key. SOLUTION: A key signal analysis part 4 inputs the key signal that is outputted when an optional character input key 2 is pushed by a user on a keyboard and decides whether the key signal shows a character or the mode change. If a mode change signal produced by the push of an input mode change key 3 is decided, the stroke that is assigned to a mode set after the change of an input mode is given to the key 2. Thus the user can know the change of the input mode while performing a non-visual keying operation and therefore can improve the operability for confirmation of the input mode.

Abstract: PURPOSE:To prevent the malfunction of a dial sending circuit beforehand and to prevent the sending of an erroneous dial signal by comparing the direct current voltage of a line edge with a reference voltage set beforehand, when the direct current voltage is reduced to a reference voltage or below, generating a control signal and setting a dial sending circuit to a non-action condition. CONSTITUTION:A direct current voltage deciding circuit 61, when a direct current voltage between line terminals 2a and 2b is detected, the direct current voltage is level-compared with a reference voltage set beforehand and the direct current voltage is the reference voltage or below, continues to generate a control signal until a direct current voltage is returned to a voltage higher than the reference voltage by the prescribed value only. A control signal is respectively supplied through a power source switch 33 and a latch circuit 54 to a power source switch 53. The power source switch 33, when the control signal is supplied, stops the supplying of the direct current electric power to a dial sending circuit 31 and sets the dial sending circuit 31 to a non-action condition. On the other hand, the power source switch 53, when the control signal is supplied, stops the supplying of the direct current power to a receiving amplifying circuit 51, and thus, sets the receiving amplifying circuit 51 to a non-action condition. Simultaneously, the control signal is supplied even to an indicator 62 and the reduction of the direct current voltage is informed to a speaking person.

Title: Current limiter
Inventor: MORI SADAJIRO
IPC: H02H9/02
Filed: 1987-07-15
Abstract: PURPOSE:To lengthen service life of a series circuit of a thyristor, a resistor and a series power source, by feeding current having magnitude higher than an inherent critical level through a superconductor. CONSTITUTION:Upon firing of thyristors 27, 127, current is fed from series circuits 25, 125 through thyristors 27, 127 to superconductors 24, 124 and lapped over existing current. When the total current exceeds over a critical current level of the superconductors 24, 124, superconducting state of the superconductors 24, 124 is missed and high resistance is provided to limit load current. Upon missing of superconducting state, Joule's heat is produced in the superconductors 24, 124 to rise the temperature of the superconductors which is not recovered to superconducting state but maintained in high resistance state. A switchgear (not shown) is opened under this state to interrupt current. Consequently, a series body of thyristor, resistor and D.C. power source is not consumped even after repeated use, resulting in a lengthened service life.

Filed: 1988-07-15
Abstract: PURPOSE:To stabilize a traveling property in repetitive use and to prevent the deterioration of image quality by jitters by laminating a thin ferromagnetic metallic film, diamond-like carbon film and lubricating agent layers to one surface of a high-polymer film and disposing a porous carbon film to another surface. CONSTITUTION:The thin ferromagnetic metallic film 12, the diamond-like carbon film 13 and the lubricating agent layers 15A, 15B are laminated on one surface of the high-polymer film 9 and the porous carbon film 14 is disposed on another surface. Both the surfaces are carbon if the recording medium is constituted in such a manner. The lubricating agents are then moved by transfer so as to exist always at an equal amt. on the surfaces when the high-polymer film is wound and, therefore, the property to retain the lubricating effect is improved. Since the rear surface consists of the porous carbon, the total adsorption amt. of the lubricating agents is increased and the property to retain the lubricating effect is improved. The traveling property in the repetitive use is improved and the degradation in the image quality by the jitters is prevented in this way.
