Title: Chrominance signal processing circuit
Inventor: HATA TAKASHI
IPC: H04N9/455
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To remove distortion in phase and amplitude of a burst signal and to suitably drive a color demodulation circuit by raising a burst gate pulse in a period shorter than the period of a burst signal. SOLUTION: The chrominance signal processing circuit 10 includes a phase detection circuit 18, which detects a phase difference between an oscillation frequency signal outputted from a VCXO 22 and a burst signal. An oscillation frequency signal from the VCXO 22 is controlled based on the detected signal outputted from the circuit 18. Thereby the oscillation frequency signal controlled in frequency is applied to a burst gate pulse generation circuit 16. The circuit 16 divides the frequency of the oscillation frequency signal and generates a burst gate pulse to be raised at a prescribed period of the burst signal which is shorter than the burst signal period. The circuit 18 is activated in the rise period of the burst gate pulse.

IPC: G01M1/14
Filed: 1978-03-31
Abstract: PURPOSE: To accurately measure the unbalance between the two right and left sides of a test piece by applying known test weight to the right side of the piece.  
     CONSTITUTION: The detected signals of vibration detectors 1 and 2 are fed through amplifiers 3 and 4 to filters 17 and 19. These filters 17 and 19 are supplied with pulses. These pulses are reference phase signals, from which the synchronous components synchronous with the rotations are extracted by the filters 17 and 19. The outputs of component separators 18 and 19 are generated at the left and right sides lp and rp, respectively, and are fed to a switching circuit 6. The outputs from the filters 17 and 19 are the unbalance vector signals of the test piece, e.g., x and contain the data of a preset unbalance 4 and an unbalance angle θ. These data are used to generate their respective values in accordance with the components from the separators 18 and 20.

Title: Alarm clock
Inventor: SHIRAI TOSHIAKI
IPC: G04C21/16
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To regulate the sound regulation of an alarm clock by light emitting state, and set the alarm sound without annoying a person in the same room even in a dark place. SOLUTION: When a sound confirming switch 6 is pressed, an alarm signal S1 becomes 'H' to make an alarm driving circuit 3 operable. At the same time, a sounding device 4 is non-soundable, and a light emission driving circuit 5 is operated. An alarm drive signal S2 formed by the alarm driving circuit 3 is inputted to the light emission driving circuit 5, and a light emitting device 7 emits a light at a flashing period corresponding to a set sound volume. A sound regulating means 3a is regulated while pressing the sound confirming switch 6 to set a desired sound volume, whereby the setting of the alarm sound is completed. Thus, the sound volume can be regulated even in a dark place without generating the alarm sound and lighting.

Title: Apparatus for preventing generation of weft bar in loom

IPC: D03D49/12
Filed: 1991-03-06
Abstract: PURPOSE:To prevent the generation of weft bar caused by the interference between a guide bar and a cloth fell by the slow normal rotation or slow reverse rotation of a loom. CONSTITUTION:A feeding motor 1 is rotated at slow speed in normal direction prior to the slow reverse rotation or slow normal rotation of a loom motor M to prevent the weft insertion miss. The operation of the feeding motor 1 is controlled by a control computer C and the feeding motor 1 is rotated at slow speed in normal direction to a prescribed extent to move the cloth fell W1 from the swinging range of a reed 6 to the side of a woven cloth W. In the case of restarting the weaving operation, the feeding motor 1 is rotated at a slow speed in reverse direction to return the cloth fell W1 to the original position. The normal or abnormal state of the displacement of the cloth fell position can be grasped by the control computer C based on the information on the rotation transmitted from a rotary encoder 1a of the feeding motor 1. When the abnormal state is generated in the displacement of the cloth fell position, the reverse rotation of the motor is continued until the detected tension obtained by a load cell 15 reaches the warp tension immediately before the displacement of the cloth fell position.
