摘要： PURPOSE:To make it possible to form a large number of hard macro-cells in a chip with no need for wiring space by providing a hard macro-cells with input and output terminals on each of the four sides, upper/lower and left/right, thereof. CONSTITUTION:A hard macro-cell is constituted of a Vcc line 1, GND line 3, Al wirings 5, one block 6, one unit 7, input terminals 2 and output terminals 4 of the hard macro-cell; One of the input terminals 2 and one of the output terminals 4 are formed on each one of the four sides, upper/lower and left/light, of the hard macro-cell. In forming a wiring to the input terminals 2 and output terminals 4, connection is possible on any side. This eliminates the need for extra space for wiring and increases the number of hard macro-cells per chip.

摘要： PURPOSE:To obtain a locally deformable sheet and to easily electrically seal a circuit of an arbitrary shape by connecting a conductive sheet of a metal cloth having flexibility and an insulation sheet having flexibility of a thin film by conductive adhesive of the thin film, and forming an integrated sheet. CONSTITUTION:A surface sheet 1 having conductivity is formed of a flexible aluminum thin plate or metal cloth knitted by metal yarns. On the other hand, a rear surface sheet 2 having insulation is formed of a thin film insulation sheet made of polyethylene, etc. The sheet 1 and the sheet 2 are adhered through a conductive thin film adhesive 3 to form a flexible shielding sheet 4 of sandwiched state. The sheet 4 has flexibility, and can easily be deformed locally by applying a local force. When a circuit 6 in a housing 5 is covered, the shielding sheets are matched to the housing and brought into close contact with one another by applying a local deformation.

摘要： PURPOSE:To obtain a small sized and inexpensive antenna by which radio waves from plural satellites are selectively received at a high speed with high accuracy. CONSTITUTION:A mast 2 fixes an antenna 1 and a mast 4 arranged concentrically to the mast 2 and supporting the mast 2 is fixed to a pedestal (not shown). One end of a supporting rod 6 made of a piezoelectric actuator is fixed to the mast 4 (through a guard 5, a half-cut ring 12, an arm 11 and a supporting rod stator 9) and expanded/contracted. The displacement of the expansion/ contraction of the supporting rod 6 is converted into a turning displacement of the mast 4 by a displacement force conversion means (composed of a bearing 3, a spring 7, a block 8 and a spring retainer 10).

摘要： PURPOSE:To arbitrarily control a reflecting plane at high speed without providing the movable part of a motor or a bearing, etc. CONSTITUTION:A holding ring 1 is serially and circumferentially connecting piezoelectric elements 2, and a controller 4 changes a voltage to be impressed to those piezoelectric elements 2 and time for the impression. Since a reflecting board 5 is stuck to the holding ring 1 and radio waves or the like are radiated to the reflecting board 5 deformed by impressing the voltage, the reflecting direction can be controlled at high speed even without providing the movable part of the motor or the bearing, etc.

摘要： PURPOSE:To suppress the deterioration of a transistor, and simultaneously, to shorten the switching time of a head current. CONSTITUTION:A first and a second NPN transistors Q1, Q2 whose bases are connected to input terminals VIN1, VIN2 respectively, a third and a fourth NPN transistors Q3, Q4 whose collectors are connected to the emitters of the transistors Q1, Q2 respectively, a constant current source 5, and delay circuits 1, 2 connected between the input terminals VIN1, VIN2 and the bases of the fourth and the third transistors Q4, Q3 respectively are provided. Besides, a head 3 and a surge absorbing resistor 4 invert the first and the second transistors Q1, Q2, and after that, they invert the third and the fourth transistors Q3, Q4. Even if the surge absorbing resistor 4 is made large, and the surge voltage of the head 3 is made high, reverse bias voltage to be impressed between the emitter and the base of the first transistor Q1 is suppressed below the withstanding voltage.

摘要： PURPOSE:To make the resetting of an object unnecessary and to efficiently and simply measure the center of gravity of the object of every kind, by providing an equilibrium stand on the horizontal stand on a plurality load sensors subjected to planar arrangement in a tiltable manner in a vertical direction. CONSTITUTION:After an equilibrium stand 5 is held horizontally, an object 6 is placed on said stand 5 at a proper position to measure load values of load sensors 2a, 2b, 2c. The center-of-gravity position (x1, y1) of the object 6 in X- and Y-directions is calculated from the plane coordinates positions of the load sensors 2a, 2b, 2c and the measured values (A1, B1, C1) of the sensors. Subsequently, the equilibrium stand 5 is shaken around support posts 4, 4 while the object 6 is placed thereon to be brought to a state inclined at an angle theta. Then, the center-of-gravity position (x2, y2, z2) of the object in an (X, Y, Z) direction from the measured values (A2, B2, C2) of the load sensors 2a, 2b, 2c and from the inclined angle theta is obtained by calculation.

摘要： PURPOSE:To make the device small and the weight light by providing an ultrasonic wave motor having a rotor fixed to one end of a cylinder of a rotary guide coaxial with a stator and driven by an external power supply to the device. CONSTITUTION:A rotor 52 and a stator 51 are arranged coaxially in contact with each other, a voltage is applied to a piezoelectric body 512 to vibrate the stator 51 in axial direction. A vibration in terms of a travelling wave travelling as lapse of time is excited in the circumferential direction of the stator 51, an elastic body 511 is resonated to the travelling wave to drive the rotor 52 in contact with the elastic body 511 of the stator 51 axially. In this state, an ultrasonic motor 5 is driven by an external power supply to drive a rotary guide 1 by 90 deg.C around the rotary shaft 6. Thus, the high frequency power energy inputted to the outside of the guide 7a is transmitted to the guide 7d with the guide 3b connecting to the guide 7a. Thus, the size is made small and the weight is made light.

摘要： PROBLEM TO BE SOLVED: To provide an operational amplifier circuit with a stable frequency characteristic, in which a common mode input voltage range is as wide as, e.g. 0 to Vcc-1.0(V). SOLUTION: This operational amplifier circuit is made up of a Darlington differential amplifier circuit 10, consisting of transistors(TRs) of a conduction type (pnp) and a single differential amplifier circuit 20, consisting of TRs of the same polarity (pnp), and a changeover circuit 30 that selects either of the differential amplifier circuits, depending on an input voltage. Thus, the common mode input voltage range is widened, and each TR for the Darlington differential amplifier circuit 10 and the single differential amplifier circuit 20 is of the same conduction type and operated by a same constant current I1, so that the frequency characteristic is not changed through a changeover.
