Abstract: PROBLEM TO BE SOLVED: To obtain a wave making apparatus by which a precise waveform can be generated, by a method wherein a connecting rod which maintains a rectilinear reciprocating motion and a wave making plate are connected by a flexible joint, and the height of the connection point of both is made always constant. SOLUTION: A driving motor 101 in a driving mechanism K is driven, and a ball screw 102 is turned forward and reversely. Then, a linear way 107 is moved rectilinearly back and forth along a linear guide 103. By its movement, a connecting rod 301 is moved rectilinearly back and forth while its horizontal state is being maintained. The connection point S of the connecting rod 301 connected by a flexible joint F to a wave making plate 106 is moved rectilinearly back and forth on the same plane as the connecting rod 301. At the same time, a sliding bar at the tip of the connecting rod 301 is slid at the inside of a sliding groove. The wave making plate 106 is rocked and moved around a joint 109. As a result, the rotation of the driving motor 101 is converted into the reciprocating motion of the wave making plate 106, and waves W are generated.  In this manner, when the height of the connection point S is made always constant, a precise waveform can be generated.

Title: Hall element
Inventor: OONO MASANORI
IPC: H01L43/06
Filed: 1978-04-28
Abstract: PURPOSE: To obtain a Hall element which generates no unbalance voltage by providing two Hall elements onto the same substrate under the same conditions, by forming current electrodes with their direction perpendicular, and by connecting the electrodes so that unbalance voltages obtained by voltage electrodes will cancel each other.  
     CONSTITUTION: Electrodes of 131 and 221 of Hall elements 11 and 12 are supposed to be formed being shifted in the right upper direction from electrodes 132 and 222. When currents are fed to terminals 21 and 22 in magnetic field 0, element 11 has potential (e 131 ) greater than (e 132 ) and element 12 has (e 232 ) greater than (e 231 ). Elements 11 and 12 are formed closely under the same conditions, so that an equation of e 131 -e 132 =e 232 -e 231  can be obtained. Therefore, when electrodes 131 and 232 high in potential are coupled while e 132  and e 231  are connected to voltage terminals 31 and 32 respectively, potential differences cancels mutually and the voltage between voltage terminals 31 and 32 is zero, that is to say, the unbalance voltage is zero. Applying a magnetic field to elements 11 and 12 adds a Hall voltage, so that a double voltage can be obtained from terminals 31 and 32.

Title: Communication system by order wire
Inventor: NEGISHI TAKESHI
IPC: H04J3/00
Filed: 1988-03-07
Abstract: PURPOSE:To execute a communication between respective stations by means of a single OW burst to 1 frame by alternately transmitting the burst for an order wire(OW) once for 2 frames from each station. CONSTITUTION:A frame number counter 3 counts a frame pulse FR PLS to be inputted, the period of the wiring or reading of memories 7 and 8 are made into 2 frames, and they are switched by selectors 5 and 6. Since an OW GATE 1 for a memory writing is inputted by a timing to receive once for 2 frames and the length is the number of bits corresponding to 2 frames, burst data OW BST to be received by a self-station once for 2 frames are written to the memory, and simultaneously, the reading is also executed in being successive between 2 frames. Thus, by alternately transmitting the OW burst once for 2 frames by each station, in spite of a single OW burst to 1 frame, a bidirectional communication can be executed as though two OW bursts exist.

Filed: 1989-03-02
Abstract: PURPOSE:To measure the modulus of elasticity of ceramics with high accuracy by integrating a piezoelectric element with a sample to be measured, determining the resonance frequency thereof and correcting the resonance frequency with an equiv. circuit. CONSTITUTION:The piezoelectric element 2 is adhered to the sample 1 to be measured and an electrode 3 is mounted thereon. The equiv. circuit of this time is illustrated and the modulus of elasticity is measured in the following manner: A sine wave is generated by a frequency synthesizer and while the frequency thereof is changed, the wave is applied to the sample to be measured and a reference device. After the respective outputs are amplified, the voltage is measured by a voltmeter and the resonance point is determined from the change in the voltage of this time. The resonance frequency is then measured. The need for the signal conversion between the sample to be measured and a detector is eliminated according to this method and, therefore, the modulus of elasticity of the ceramics is measured with the high accuracy.

Abstract: PURPOSE:To prevent a press formed part from being deformed by spring-back by applying force in the direction vertical to the plate surface by impact hydraulic pressure as the whole process of a final plate of a metallic press-formed previously. CONSTITUTION:When an end face of a piston 11 is hit by a weight 14, the piston 11 is driven instantaneously into an impact pressure generating cylinder 9. When the piston 11 is driven, pressure of a liquid in the impact cylinder 9 ascends impulsively, impact pressure is generated in a hydraulic pressure chamber 2 allowed to communicated through a hydraulic pressure transfer line 10, and working is executed by pushing the whole surface of a metallic panel W for closing up tightly an opening part in the hydraulic pressure chamber 2 against the forming surface 4a of a die 4 by impact pressure vertical to the plate surface of the respective parts. Therefore, with respect to the metallic panel W formed in a prescribed shape, working in the direction vertical to the plate surface of the panel W, that is, the direction for compressing the plate thickness of the metallic panel W is applied as final working, by which deformation of the metallic panel W caused by spring-back is suppressed.
