Title: Measuring method for surface temperature of printed wiring board
Inventor: SAITO HAJIME
IPC: G01K7/08
Filed: 1990-03-30
Abstract: PURPOSE:To make it possible to measure surface temperature directly and accurately by directly welding metal materials which can become thermocouples on the surface of a printed wiring board, and performing the measurement. CONSTITUTION:Circuits patterns 2 and 3 are formed on a printed wiring board 1 by, e.g. etching a copper foil. A piece of constantan wire 4 having the diameter of about 0.1-0.3mm is welded to a bonding part 5 for one end of the circuit pattern 3. A piece of copper wire 6 having the diameter of about 0.1-0.3mm is welded to a bonding part 7 for the other end of the circuit pattern 3. The constantan wire 4 and the copper wire 6 are connected to a measuring device 8, and thermal electromotive force is measured. Different from a conventional method for pushing thermocouples, inaccurate measurement due to poor pushing, deviation and the like is eliminated, and the accurate measurement can be directly performed. This method is effective especially when the wiring board itself becomes a heater.

Title: Underwater level measurement
Inventor: YAMAMOTO IICHIROU
IPC: G01S5/28
Filed: 1984-04-23
Abstract: PURPOSE:To facilitate a drastic reduction in the measuring time by emitting interrogation signals simultaneously to first and second sound wave responders from a sound wave transmission/reception measuring apparatus. CONSTITUTION:When interrogation signal frequencies f0 and fx are emitted simultaneously to first and second sound responders 12 and 21-23 from a sound wave transmission/reception measuring apparatus 11, the devices 21-23 receive the frequency fx and emits sound waves of frequencies f1, f2 and f3 in response thereto. On the other hand, the device 12 receives the frequency f0 and emits a sound wave of the frequency fx in response thereto. The sound wave is received with the device 11 while done with the devices 21-23, which emit sound waves of frequencies f1-f3 in response thereto and these sound waves are received with the device 11 again. Therefore, the apparatus 11 calculates the distance between the apparatus 11 and the device 12 from a time difference between the time of oscillating the frequency f0 and the time of receiving the frequency fx, and the intervals between the apparatus 11 and devices 21-23 from the time difference between the time of oscillating the frequency fx therewith and the time of receiving the frequencies f1-f3 therewith to determine the distance. Thus, the measurement of level is enabled. At this point, the reduction in the measuring time is made possible by transmitting the interrogation frequencies f0 and fx simultaneously from the apparatus 11.

Abstract: PROBLEM TO BE SOLVED: To provide a surface acoustic wave(SAW) device capable of improving a temperature characteristic while keeping a high electric/mechanical connection coefficient (K2) characteristic and advantageous in miniaturization by specifying the relation between the pitch of an electrode and the thickness of a piezoelectric substrate. SOLUTION: This SAW device 5 has a glass substrate 1, a piezoelectric substrate 2 and electrodes 3. The piezoelectric substrate 2 is formed on the glass substrate 1 and consists of LN. The electrodes 3 having arrangement corresponding to the device are formed on the piezoelectric substrate 2. When the thickness of the piezoelectric substrate 2 is H, the pitch of the electrodes 3 is λ and K is 2π/λ, KH is regulated to 1.6-1.8. Thus, electric field distribution differs by the thickness H of the LN substrate 2 and the electrode pitch λ. Thus, the electric field distribution is adjusted to concentrate on the LN substrate 2 by setting KH to 1.6-1.8. Consequently, the SAW can effectively be excited and K2 is improved.

Abstract: PURPOSE:To reduce influence of a circumferential elongating and contracting motions to disturb a deflecting vibration to be generated by radial elongating and contracting motions by reducing a circumferential width of a vibrating element. CONSTITUTION:A piezoelectric vibrator 3 provided with an electrode pattern 12 is formed at a stator 1. The vibrator 3 is polarized in the same direction. A vibrating element is formed of a shaded electrode pattern 12.

In this case, a node is formed at a fine line 13, and a standing wave of triple wavelengths is excited. The vibrating element of an ultrasonic motor is circumferentially divided at 60 deg. or below. Thus, one wavelength becomes 1/2 or below for 120 deg.. The motor is not limited to the triple wavelengths. For example, in the case of double wavelengths, the circumferential angle of the element may be set to 1/4 or 180 deg. of one wavelength, i.e., 90 deg. or below.
