Title: Ink jet recorder
Inventor: OTA YOSHIHISA
IPC: B41J2/045
Filed: 1996-01-18
Abstract: PROBLEM TO BE SOLVED: To make it possible to stably discharge ink droplet in a variable area after the droplet is discharged and to improve the discharge frequency by eliminating the discharge of the ink in an area that the ink droplet volume is abruptly deceased as the droplet discharge timing is lengthened. SOLUTION: The maximum driving frequency fmax is set so that the ink droplet discharge timing is existed in the variable area 7 that the ink droplet volume is increased as the droplet discharge timing is lengthened in the first variable area of the earliest timing in the variation of the ink droplet volume Mj at the droplet discharge timing. Thus, the ink droplet discharge failure scarcely occurs due to the bubble engulfing, the ink droplet discharge can be stably conducted, and stable ink droplet discharge can be conducted under all driving conditions. The change in the meniscus and the ink droplet discharge characteristics are largely related, but the actually driving frequency is driven by 1/n (n is integer) or 1/(n+0.5) of the maximum driving frequency fmax.

Title: Metal adding electron beam welding method
Inventor: MIZUTA TOSHIJI
IPC: B23K15/00
Filed: 1988-01-14
Abstract: PURPOSE:To uniformize the chemical composition of the adding metal in a welding metal and to improve the joint performance of a weld zone by executing a metal adding electron beam welding, projecting the electron beam in plural times on the weld zone as well and remelting the molten metal. CONSTITUTION:The body 1 to be welded is welded by projecting an electron beam 2 by using a filler wire, etc., to form the electron beam welding metal 6 to which a metal is added. The electron beam 2 is then projected in plural times on the same line or at its vicinity. Said welding metal 6 solidified by this projection is remelted to promote an agitation and the uniformity of an additive is advanced by increasing the number of remelting times. The uniformization of the adding metal chemical composition in said welding metal 6 is thus achieved and the joint performance of the weld zone can be improved.

Title: Data receiver
Inventor: TSUBAKI KAZUHISA
IPC: H04L27/22
Filed: 1993-01-19
Abstract: PURPOSE:To surely decode reception data by generating a zero cross signal to all data patterns of QPSK so as to correct an identification timing for each symbol thereby synchronizing a transmission speed with that of a transmission station. CONSTITUTION:A detector 3 generates a 1st base band signal from a reception signal and a detector 4 generates a 2nd base band signal. An identification device 6 identifies the polarity of the 1st base band signal based on an identification timing of data detected and recovered through a zero cross signal of the 1st base band signal at a clock recovery device 5 and outputs received data based on the result. Furthermore, a frequency of a transmitter 2 is controlled by an error signal produced in this case to trace the frequency with a carrier frequency. Thus, a zero cross signal is generated with respect to all QPSK data patterns and an identification timing is corrected for each symbol to take synchronization of a transmission speed with the transmission station and reception data are surely decoded.

Title: Fault detection system of error amplifier
Inventor: TAKATSU KAZUHISA
IPC: H03F1/32
Filed: 1985-01-18
Abstract: PURPOSE:To detect easily a fault of an error emplifier by inserting a band stop filter blocking a supervisory signal to a delay circuit side of an error detection loop and supervising a level of the supervisory signal at the output side of a feedforward amplifier. CONSTITUTION:When the error amplifier 7 is faulty and the gain is abnormal, the supervisory signal appears at an output terminal OUT. Thus, the fault of the error amplifier 7 is detected easily by supervising the level of the supervisory signal at the output terminal OUT. Then a hybrid circuit 13 is inserted to superimpose the supervisory signal from the supervisory signal oscillator 12 onto the input signal to the input side and a band stop filter 14 to stop the supervisory signal is inserted to a delay line 3 of the error detection loop. Thus, the supervisory signal does not appear at the output terminal OUT at normal state, and when the error amplifier 7 is faulty and the gain is abnormal, since the supervisory signal appears at the output terminal OUT, the fault of the error amplifier 7 is detected easily by supervising the level of the supervisory signal at the output terminal OUT.

IPC: H01L41/08
Filed: 1983-01-19
Abstract: PURPOSE:To make it possible to apply voltage regardless of temperature, by applying a driving voltage, whose direction is the same as the polarizing direction of one piezoelectric plate, making the polarizing direction of the other piezoelectric plate to be at the same potential, and vibrating a vibrator in the direction of the thickness of the plates. CONSTITUTION:A bimorph vibrator 1 is constituted by combining PZT piezoelectric plates 1a and 1b. The piezoelectric plates 1a and 1b are polarized in the thickness of the plates, and the side of the connecting surfaces is made to be a negative electrodes. The electrodes and a relay 2 are connected by lead wires 4a, 4b and 4c. The relay 2 and a power source 3 are connected by a positive voltage side lead wire (p) and a grounding side lead wire (n). When a positive voltage is applied to the lead wire 4a, an electric field, whose direction is the same as the polarizing direction from the wire 4a to the wire 4c, is generated in the plate 1a, and the plate 1a is contracted in the longitudinal direction. As a result, the vibrator 1 is bent to the left side and vibrated. When the positive voltage is applied to the lead wire 4b, the vibrator is bent to the right side.

Filed: 1999-01-13
Abstract: PROBLEM TO BE SOLVED: To optimize a circuit area by assuming clock tree synthesis for optimization of clock signal timing skew at an arrangement/wiring process, for optimizing a logic circuit in a logical synthesization process. SOLUTION: In a logical synthesis, a clock driver 13 connected to a clock terminal of a flip flop 10 is limited.

The number of block blocks allowed to be connected and a circuit area for the output terminal of the clock driver 13 is defined to be identical with the fan out number of the clock driver 13 used in a clock tree synthesis performed in an arrangement/wiring process. Thus, such gate level circuit as a circuit area is equal to a gate level circuit is synthesized with an optimum circuit area at logical synthesis.

IPC: G10L25/90
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To obtain an articulate speed-converted speech without varying the interval of a speech signal which is recorded on a recording medium. SOLUTION: An input speech signal 1a is sent from a speech signal storage memory 1 to a voiced/voiceless decision pat 2. The voiced/voiceless decision part 2 decides whether the input speech signal 1a is voiced or voiceless and sends the decision result as a switching flag 1b to a changeover switch 3. The changeover switch 3 sends the input speech signal 1a to one of a speaking speed conversion part 4 and an adder 5. The speaking speed conversion part 4 converts the speed of an input speech signal 1c for speaking speed conversion and sends a speaking speed converted speech signal 1e to the adder 5.  The adder 5 adds the speaking-speed unconverted speech signal 1d and speaking- speed converted speech signal 1e together and records the result as a speaking- speed conversion output speech signal 1f in an output speech signal storage memory 6, so thereby obtaining a speech signal whose waveform information of a voiceless part is not altered.
