Title: Electronic circuit board and method for correcting disconnection of wiring thereon
Inventor: HONGO MIKIO
IPC: H01L21/283
Filed: 1999-07-05
Abstract: PROBLEM TO BE SOLVED: To correct the wire disconnection defect without increasing production cost and damaging the reliability of a product, by irradiating a laser beam on a solution or a coating film on a wiring disconnection part which contains a prescribed metal complex, metal alkoxide and β-diketone. SOLUTION: In the case of correcting a defective in which a part of wiring is lacked on a TFT substrate used as an electronic circuit board, i.e., a wire disconnection defective, a liquid in which a metal complex is dissolved in an organic solvent is used as a liquid material for correcting a wiring disconnection defective 10. Namely, a solution in which ultra-fine metal particles of any of palladium, gold, silver and platinum are dispersed in the organic solvent is used. Metal alkoxide for improving bonding characteristics and β-diketone for securing the stability of the metal alkoxide are added to the solution. As the metal complex, a subject in which Pd (CF3COO)2 (trifluoropalladium acetate) is dissolved in N-metil-2-pyrrolidone and acetonitrile is preferable.

Title: Clock generation circuit
Inventor: FUJII KUNIHIKO
IPC: H04N5/46
Filed: 1997-07-15
Abstract: PROBLEM TO BE SOLVED: To provide a stable operation with a simplified structure by generating a luminance signal sampling clock by a digital processing from a clock that synchronizes a reference oscillation frequency with the horizontal synchronizing signal of a high vision signal. SOLUTION: A VCO 3 outputs a reference signal of f=27 MHz for a frequency divider 5 based on the reference oscillation frequency of an oscillator terminal 1b. In the case of an NTSC signal, the frequency divider 5 outputs a result of frequency dividing this reference signal to 1/1716 as a frequency demultiplexed signal from a relation f=1716 fN between a horizontal synchronizing frequency fN and a reference oscillation frequency f. A phase comparison of this frequency demultiplexed signal with an NTSC horizontal synchronizing signal SYNC-SD is performed and, when both are non-synchronizing, a differential signal is outputted to an LPF 4 by way of a switch 7. The LPF 4 performs a smoothing of a phrase difference and feeds back to the VCO 3. By repeating a feedback operation of a control signal like this way, a PLL control is executed.

Title: Sound recording medium
Inventor: FURUKAWA SANSHIROU
IPC: G11B23/18
Filed: 1982-10-27
Abstract: PURPOSE:To enable everybody to enjoy a duet (or a chorus) by playing with stress a low-pitched sound part of a desired duet bar with a musical instrument of a recorded orchestral accompaniment and at the same time suppressing the sound volume for a melody and other sound part for recording. CONSTITUTION:For instance, an accompaniment is recorded like a conventional recorded orchestral accompaniment play for the vocal solo part of the 1st and 2nd stages, and the low-pitched sond part of a duet of the 3rd stage is played with a large sound volume by a single musical instrument. While other sound parts, i.e., the accompaniment is recorded in a small sound volume. This sound volume is controlled by the sound volume controller of a sound recorder. Sound controller is attached to each musical instrument of an orchestra to control the sound volume. In such a way, a desired low-pitched sound part is emphasized, and therefore the low-pitched sound part is played repetitively together with a reproduced accompaniment. Thus is it possible easily to enjoy a duet with an ordinary accompaniment play after learning the desired low-pitched sound part.

IPC: G06F1/30
Filed: 1996-07-19
Abstract: PROBLEM TO BE SOLVED: To record data on a recording medium built in a device even when the recording medium is absent and to distinguishably know format abnormality or medium abnormality of the medium by making it possible to distinguishably know whether or not a detachable recording medium in use is a recording medium. SOLUTION: Information for medium control is read out of the recording medium 10 and a total control part 11 makes the read information for recording medium control ineffective when detecting a line which covers the medium being opened or the source voltage dropping below a predetermined value during operation by a battery. Consequently, a processing at error time is simplified and if the recording medium 10 is taken out by mistake during recording or when battery output in recording drops, no fatal data destruction on the recording medium is caused.

Filed: 1985-09-02
Abstract: PURPOSE:To obtain a desired illumination distribution without lowering the illumination by providing a movable lens for changing the illumination distribution continuously and adjusting the position of the movable lens so that a predetermined illumination distribution can be obtained on the irradiated plane. CONSTITUTION:An optical integrator 3 which functions as a secondary light source irradiates a mask plane 5 by an illumination distribution changing lens 4.

Title: Ultrasonic flow velocity measuring method
Inventor: OKAMURA SHIGENORI
IPC: G01F1/66
Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To secure sufficiently high measuring accuracy by surely recognizing the first half wave of received waves by forming the first wave of a driving pulse impressed upon an ultrasonic transmitting element in a triangular wave which rises gently and falls steeply. SOLUTION: The first wave P1 of a driving pulse P outputted from a pulse generating circuit is formed in a triangular wave which rises gently P11 and falls steeply P12 . Consequently, the waveform of the received wave which is received by means of and outputted from a receiver becomes that of the received wave W shown in the figure. Namely, the first half wave W1 of the received wave W corresponding to the steeply falling section P12 of the triangular wave P1 becomes such a waveform that becomes the highest at the peak value and descends after the peak value. Accordingly, when, for example, the half wave W1 is not able to be caught, because the reference level for measuring propagating time difference fluctuates and exceeds the peak value of the half wave W1 of the received wave W1 no output is generated.  Therefore, the measuring accuracy of an ultrasonic flow rate measuring method can be secured, because the measurement can be discriminated as invalid and the possibility of catching the second half wave W2 and waves after the half wave W2 is eliminated.
