Title: Sewing machine provided with thread cutting mechanism
Inventor: SUZUKI HAJIME
IPC: D05B69/00
Filed: 1989-10-31
Abstract: PURPOSE:To shortly remain the end part of a needle thread without being entangled with a bobbin thread on the back of a cloth by operating a thread loosening mechanism for a prescribed period after a sewing machine motor is activated in order to loosen the needle thread in a thread conditioning mechanism when sewing is started. CONSTITUTION:When a sewing machine motor 115 is driven by a sewing machine motor driving signal, the set data of a thread loosening set time data memory 141 and the set data of a needle thread releasing set time data memory 142 are respectively stored to a timer in a controller C and during a period when, for example, a sewing needle 24 falls down from the highest position to the lowest position and a needle thread loop is formed by a thread loop catcher 32, a thread loosening solenoid 20 is driven. Thus, resistance to be applied to the needle thread is removed by the tension mechanism for the prescribed period, the required amount of the needle thread is supplied from a thread supplying source and tension is not almost operated upon the upper thread. Accordingly, the needle thread is not out of a stitch hole. Since only the small resistance is operated from the cloth to the end part of the needle thread extended from the stitch hole in the first stitch, the end part of the needle thread is extended by a tip and pulled into the back of the cloth. Then, the amount of the thread from the stitch hole to the end of the upper thread is not almost changed and in the first stitch, the needle thread is not interwined with the bobbin thread.

Filed: 1993-10-25
Abstract: PURPOSE: To obtain a synchronization detecting circuit which can directly monitor phase detecting input signals by constituting the synchronization detecting circuit of a synchronization detecting circuit incorporating a NAND gate having a second input which receives first and second digital input signals. CONSTITUTION: The combination of a reference clock signal and the output signal /N of an oscillator which are respectively impressed upon the first and second inputs of a phase detector 14 generate rise and fall control signals in accordance with the phase relation between them. A charge pump 16 responds to the rise and fall control signals so as to charge and discharge a loop node 18. The voltage generated at the node 18 drives a VCO 24 so as to generate the output signal of a rushing device to an upper limit of 200 MHz and the output signal of the oscillator is lowered and divided by means of an N-frequency divider so as to supply the output signal /N of the oscillator to the second input of the detector 14.  In order to maintain a prescribed phase relation between both signals, the detector generates the rise and fall control signals which are required by the charge pump 16 which drives the node 18 and VCO 24 by monitoring the phase difference between the clock reference signal and the output signal /N of the oscillator.

Title: In-vehicle video image re-transmission device
Inventor: SUDA KAORU
IPC: H04H20/00
Filed: 1992-10-26
Abstract: PURPOSE:To watch a TV broadcast by selecting a preferred channel in a moving vehicle and to receive an excellent picture without being affected of interference of a regular TV broadcast wave. CONSTITUTION:A regular TV broadcast wave is received by a reception antenna 2 installed at the outside of a vehicle and inputted to a head end device 3. The head end device 3 distributes the received signal by a distributor 31 and uses converters 32-34 to convert a frequency channel individually. The converters 32-34 convert the received signal into a signal of a frequency channel different from a TV broadcast wave such as an intermediate mid-band frequency between a 3rd channel and a 4th channel. The signals converted by the converters 32-34 are synthesized by a synthesizer 35 and amplified by an amplifier 36 and outputted into a vehicle as a re-transmission wave 41 through a leakage coaxial cable 4. Thus, passengers in the vehicle select a retransmission wave 41 by a TV set 5 freely and watch the broadcast.
