Title: Lower treated cutting device of sewing machine
Inventor: TSUKIOKA TAKASHI
IPC: D05B65/02
Filed: 1990-10-30
Abstract: PURPOSE:To eliminate occurrence of thread cutting at the time of contact, prevent drawing off the end of lower thread nipped by a thread cutting means, and have smooth and proper cutting of the lower thread by furnishing No.2 link member which makes restriction so that the revolving speed of No.1 arm becomes uneven by means of fitting of a detent pin at the base end of No.2 arm in a cam groove formed at one of the ends, and thereby lowering the revolving speed of the No.2 arm when the lower thread is in detention. CONSTITUTION:A lower thread cutting under-cutter 1 is detained with a lower thread cutting over-cutter 2, a thread holding spring 3, and a shaft 1a, and they are arranged in the form of scissors to constitute a thread cutting means. No.2 arm 4 which contacts the lower thread to rotate it, is borne at the tip of No.1 arm 5 with the aid of a stepped screw 5a rotatably together with No.1 link member 6. The No.2 arm 4 draws out the lower thread from the bobbin while further rotating counterclockwise at a low speed. Meantime the lower thread cutting under-cutter 1, lower thread cutting over-cutter 2, and thread holding spring 3 rotate clockwise, and at last the detent part 2a of the lower thread cutting over-cutter 2 comes into contact with a stopper 8a. Thereby the lower thread is severed, and its end is held by the holding spring 3 and over-cutter 2.

Filed: 1986-12-09
Abstract: PURPOSE:To attain management job for talking and communication with an absent house very easily by providing a call display light displaying the presence of a call if an interphone slave set does not reply a call from a supervisor room to the interphone slave set placed to each housing. CONSTITUTION:The call display light displaying the presence of a call is provided when no replay is given to a call from the supervisor room. If a house is absent when the supervisor room calls the house, the housing number to be called is registered in a memory 47 by the registration operation and the registered number in the memory 47 is displayed on a display device 49 at any time and confirmed by the read operation. In the absent house, when it did not reply a call, since a call display light 18 is lighted, the lighting state of the call display light 18 is checked at the time of returning home and communication to the supervisor room is applied from the house, thereby delivering a message quickly. Moreover, in receiving the call from the house, the memory registration number is retrieved automatically to erase the corresponding to a registrated number. Thus, only house numbers not communicated are registered always in the memory 47.

Filed: 1992-09-22
Abstract: PURPOSE:To obtain a motor having a high efficiency at a high speed, in which the energy stored in a deenergized coil is transferred to a capacitor and the energy in the capacitor is used to energize another coil. CONSTITUTION:When transistors 20a, 20b are turned off during operation of a chopper circuit, magnetic energy of an exciting coil 39a is returned to a power source through a transistor 50a. When the transistors 20a, 20b are converted to interruption an end of a position detection signal, the magnetic energy of the coil 39a charges a capacitor 47a to become a high voltage since the transistor 50a is cutoff. Accordingly, an exciting current drops abruptly. When the transistors 20a, 20b are again turned on by the position detection signal, the high voltage of the capacitor 47a is applied to the coil 39a to abruptly rise the current. The rises and falls of exciting coils 39b, 39c similarly become abrupt.
