Title: Ultrasonic probe
Inventor: YAMADA KENJI
IPC: H04R17/00
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To make an ultrasonic device generally usable by heating or cooling a filler interposed between oscillators to change the rigidity SOLUTION: When a current is carried to a heating element 6, a filler 2 is heated, and its rigidity is reduced. When an oscillator 1 is vibrated in this state, the interaction of each oscillator 1 is weakened more than in non-heating, the vibration of horizontal mode of each oscillator 1 is strongly excited. Consequently, the vibration of horizontal mode is interfered with the vibration of vertical mode, and the frequency of vertical mode is thus reduced. Since the frequency of vertical mode corresponds to the oscillating frequency of the oscillator 1, the oscillating frequency becomes lower than in non-heating. Namely, the oscillating frequency can be changed between non-heating and heating, and even a single ultrasonic probe can be applied to a plurality of purposes.  When a filler 2 having metal powder included therein is heated by an induction coil, only the filler 2 is heated, different from the case of the heating element 6 or Peltier effect element, and the effect of rigidity change of the filler 2 is clearly revealed.

Title: Digital recording and reproducing unit
Inventor: OIKAWA HIROO
IPC: G11B20/10
Filed: 1989-10-03
Abstract: PURPOSE:To make the best use of the performance of a DA converter by supplying clock signals to the DA converter by eliminating interference between the clock signals generated from plural oscillation circuits and interference with the clock signals generated from a digital signal processing circuit. CONSTITUTION:The clock signals generated from plural oscillation circuits 8-10 are supplied to the digital signal processing circuit 4 through independent invertors 12-14. When a first oscillation circuit 8 is selected, it is oscillated from a control circuit 11, the other oscillation circuits 9 and 10 are stopped, and a selector 16 selects the liquid crystal oscillation circuit 8. Then, a clock is supplied to the DA converter 6 and the clock signals are supplied to the digital signal processing circuit 4 through the first invertor 12. Consequently, the clock signals can be supplied without interference between the clock signals generated from the oscillation circuits 8-10 and interference with the clock signal generated from the circuit 4. Thus, the best use of the performance of the DA converter 6 is made.

Abstract: PURPOSE:To enable the maintenance of a stable discharge by low power by opposing first and second electrodes to each other and making the second electrode hollow and providing it with grid holes which allows a gas to pass and providing a third electrode inside the second electrode. CONSTITUTION:A second electrode 15 is hollow and is provided with grid holes on the plane facing a first electrode 14. A third electrode 17 is arranged in the inside space of the electrode 15 and a d.c. voltage is applied between those electrodes 15 and 17 by a d.c. electrode 21. Also in the hollow space of the electrode 15, a material gas B is introduced through a gas inlet pipe 19. In a chamber 10, a material gas A is introduced through a gas inlet pipe 12. Furthermore, a high-frequency a.c. voltage is applied between the electrodes 14 and 15 by a capacitor 22 and an RF current 20. A plasma generated in the space inside the electrode 15 diffuses into the chamber 10 through the grid holes of the electrode 15, so that the low impedance between the electrodes 14 and 15 is retained by that diffusion plasma. Accordingly, between the electrodes 14 and 15, even if a low-power discharge is effected, it can be made stable.

Abstract: PURPOSE:To always control the toner concentration in a proper range in spite of a variance of the detecting characteristic of a toner concentration sensor and to obtain an improved image with stability by preparing a toner concentration of the initial developer higher than the middle value of the prescribed range. CONSTITUTION:A toner concentration control part 10 revolves a toner replenishing roller 4 by corresponding to an output voltage V as a detecting signal transferred from a toner sensor 9 for a period of a prescribed time and the toner is replenished to an inside of the developing tank 2 with an adequate quantity.

Abstract: PURPOSE:To correct pattern distortion with simple circuit constitution and high accuracy by controlling a deflection output based on a beam detection output of a linear beam detection sensor provided adjacently at the outside of an effective fluorescent screen of a cathode-ray tube. CONSTITUTION:Two linear optical sensors 6a, 6b are provided at the outside of the effective fluorescent screen 2a of the cathode-ray tube 2.

Abstract: PURPOSE:To reasonably recover a plow for a short time even steeply deviating from a set tilling depth of the plow by installing a controlling means correcting a controlling amount in increasing with approximately proportional to an amount of a set value in a draft setting device. CONSTITUTION:Detected values detected by a height to the ground detector 23 and draft detectors 17 and set values by a height to the ground setting device 21 and draft setting devices 18 are read into a CPU. An averaged value of detected values by the left and right draft detectors 17 is calculated and a true deviation is operated from the averaged value and the set values. Resultant true deviation is multiplied with a correcting coefficient and an apparent deviation used in the control is decided. For a requirement of outputting in a direction of raising the plow, 'ON' time of a pulse due to the deviation is decided and a solenoid of a rising proportional controlling valve 46 is driven. On the other hand, for a requirement of lowering, a solenoid of a lowering proportional controlling valve 47 is magnetized.

Title: Abbreviated access system for extended address
Inventor: ONO KIZO
IPC: G06F13/16
Filed: 1986-10-31
Abstract: PURPOSE:To improve the performance of the titled access system by setting the information on an addressing bus to show the areas in the same memory block and giving an access to a memory in one or several times of addressing instead of (n) times of addressing. CONSTITUTION:A same block instructing signal B is supplied and a normal extended address system is applied when the signal B is equal to T. Then the address system works by (n) times of addressing. In this case, a memory controller sets a BT if the controller itself is selected and then resets the BT if the controller is not selected. When accesses are continuously given to the same block, a CPU sets the B at T and then sets only the addresses in the same block to an address bus. The memory controller knows that its own block is selected by the BT and the B and receives the address in the block. Thus just a singe time of addressing suffices within the same block with the extended address information that always requires (n) times of address information.

Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To measure the gas component and liquid component of a fluid flow accurately over a wide range of fluid density by providing a fluid channel with a restrictor connected in series to a flowmeter. SOLUTION: A fluid channel 10 includes a multiphase flowmeter 18 connected in series to a restrictor 20. Outputs from pressure sensors 26, 28 connected to the input and output or restrictor 20 are fed to a computer 30. The computer 30 compares the difference of pressures detected through the sensors 26, 28 which a threshold value and actuates a valve 24 when the pressure difference exceeds a predetermined value. When the pressure drop across the restrictor 20 is lower than a threshold value, the computer 30 sustains the open state of valve 24 so that a gas is fed through a fluid channel 12. Consequently, the channel 12 serves as a bypath for high speed gas. The computer 30 outputs a designated value of combined total gas flow measured through the multiphase flowmeter 18 and a gas flowmeter 22 along with water flow and oil flow measured through the multiphase flowmeter 18.
