Title: Saw force sensor
Inventor: TAKAHASHI YOSHIFUMI
IPC: G01D5/48
Filed: 1985-10-28
Abstract: PURPOSE:To obtain a highly-sensitive sensor whose temperature and change with time are compensated, by providing a heating resistor on a surface elastic wave (SAW) delay line for compensation, by making a current flow through this resistor, and by controlling the value of this current by an output of a PLL circuit. CONSTITUTION:A SAW delay line 4a (4b) is constructed by forming an electrode 2a (2b) for transmission, an electrode 3a (3b) for transmission and a heating resistor 5a (5b) on a piezoelectric substrate 1a (1b). A SAW oscillator 8a (8b) is constructed of the electrodes 2a (2b) and 3a (3b) and an amplifier 7a (7b). An output signal from the oscillator 8a is led to a PLL circuit 15 to be processed thereby and is fed back to the resistor 5a. Since a current for heating is made to flow through the resistor 5a, an output signal of the circuit 15 is increased or decreased, and thereby temperature is compensated. When a force to be measured is applied to the delay line 4b, the oscillator 8b shows a variation in frequency in accordance with this force. This output signal is inputted 16 through the intermediary of an output buffer 11b. By making flow to the resistor 5b a control current for compensation obtained from the circuit 15, the temperature and a change with time can be compensated.

Title: Image-recording apparatus
Inventor: NIIMA TORU
IPC: B41J25/316
Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To simply remove a recording medium without generating an ink stain by forming a recording head movably to a medium-holding means to be close to and away from a record position, stopping the rotation of the medium-holding means when an abnormality in transfer of the medium is detected and retreating the recording head to a protect position. SOLUTION: The image-recording apparatus has a recording head 22 formed movably to a medium-holding means 20. The recording head 22 can approach a record position where the recording head 22 can operate to record and can retreat to a protect position away from the medium-holding means 20. When an abnormality in transfer of a recording medium is detected, the medium- holding means 20 can stop and the recording head 22 can retreat to the protect position after the rotation stop of the means. An inconvenient situation caused by an immediate output when the transfer abnormality is detected, that is, caused when an operator acknowledging the transfer abnormality output forces an emergency stop although printing is not completed or the recording head 22 is still close to the medium-holding means 20 can be eliminated clearly.

Filed: 1988-09-27
Abstract: PURPOSE:To easily obtain the unstable point of a voltage by designating conditions at the buses of a power system to obtain a stable point, updating the amplitude of the voltage, so updating a phase angle as to become a load power invariable, and calculating 1 tide until the unstable point is sequentially obtained with them as an initial value. CONSTITUTION:System information from a power system 1 is input to an electronic computer 4 through information transmitters 2-1, 2-1, a tide is calculated on the basis of the information to display stable and unstable points of the system voltage. Here, a tide is calculated on the basis of the information collected from the system 1 to obtain an initial stable point, and the tide is again calculated by varying the amplitude, phase angle of the voltages of the buses of the stable point. If the variation in the voltage is small, it is converged to the stable point, while if the variation in the voltage becomes larger than a predetermined value, it is converged to the unstable point. Thus, the stable point and the corresponding unstable point can be easily obtained.

Title: Offset correcting circuit
Inventor: KONO KEIICHI
IPC: G11B21/08
Filed: 1984-11-15
Abstract: PURPOSE:To enter equivalently a state wherein no external force is applied substantially and to perform smooth seek control by flowing a necessary current to the coil of a VCM and canceling an external force applied to the movable part of the a VCM. CONSTITUTION:An offset signal OFST is applied to amplifiers 14, 16, and 18. Varous external forces applied to the movable part of the VCM are determined when a head position is fixed, so the external forces are calculated previously corresponding to respective projection lengths and stored in a ROM (read-only memory); and then the ROM is read according to the projection lengths to know the values of the external forces, which are corrected. A next cylinder address register 20 as a means for the correction is a register stored with the head position. Further, a ROM table 22 contains external forces corresponding to respective cylinder positions, concretely, offset values (current value) for canceling them. A digital/analog (D/A) converter 24 converts the readout output (digital value) of the ROM table 22 into an analog value to generate the offset signal OFST.

Abstract: PROBLEM TO BE SOLVED: To reduce miss rolls and to protect a rolling device with high reliability by providing an air pressure adjusting device for setting break-out cover pressing force properly on the working air supply passage to an actuator and switching the energizing direction of an actuator instantaneously at the time of miss rolls. SOLUTION: The actuator 10 is attached in the upper part of an upper break- out cover through a connecting rod 19. When the miss roll is generated, the buckling of a material is generated and the breakout cover is on the verge of being pushed up by larger force than setting force F, a piston 18 is moved like the arrow 40, an upper pressure-chamber 11 communicates with a discharge port 15 through an air passage 17 and released to the atmosphere, the air flows out in the atmosphere and the pressure of the air becomes zero. Simultaneously, the high-pressure air is supplied to the lower pressure-chamber. Consequently, because the large force for upward moving the piston 18 is produced and the piston 18 is moved upward instantaneously, the upper break-out cover is released.

Title: Method and device for ultrasonic image pickup
Inventor: TAKEUCHI YASUTO
IPC: G01S15/89
Filed: 1996-09-12
Abstract: PROBLEM TO BE SOLVED: To easily form the cross-sectional image of an object to be inspected by scanning the three-dimensional area of a sound field to be inspected with sound rays substantially radiated from one point. SOLUTION: A transmitting-receiving section TRX causes an ultrasonic probe PRB to transmit an ultrasonic beam into an object OBJ to be inspected by giving a driving signal. The transmitting direction of the beam is successively changed and the inside of the object OBJ is scanned with sound rays formed by the beam. Namely, the three-dimensional area of a sound field to be inspected is scanned with the sound rays substantially radiated from one point. Therefore, an arbitrary cross section set in a sound ray data space corresponds to a cross section in a physical space one to one and an image can be formed easily based on the data on the arbitrary cross section set in the sound ray data space. In addition, an actuator ACT oscillates the probe PRB in the direction perpendicular to the scanning direction.

Abstract: PURPOSE: To detect the movement of a film in a low voltage state by controlling a current used for a current limiting means with a pulse, for limiting the current used for a film detecting means, so as to actuate it at a low voltage. CONSTITUTION: Reduction in a power supply voltage is prevented by a diode 1-26 to evade fluctuations in a voltage and further, the power supply voltage before a high load is connected is maintained by a capacitor 1-25. Then, a load circuit 1-13 is connected to inspect the internal resistance of a power source and attain pulse drive for limiting the current flowing in the diode of a film movement detecting element 1-22 in a required range. The pulse drive is 10mS-50mS in the system of using the light reflection of a hole part as a perforation on the film, for instance, so that <=10mS pulse is required. Thus, in the adoption of an optical detecting system, a voltage circuit is not required in particular and an element working at the low voltage and emitting light is not required as well.
