IPC: H05K1/02
Filed: 1991-04-05
Abstract: PURPOSE:To obtain an electronic unit having high reliability against a temperature change by forming the vicinity of a connector between a connector terminal and a circuit board in a flexible structure. CONSTITUTION:A paper epoxy board 12 in which the vicinity of a connector between a connector terminal 5 and a circuit board is punched, is secured to a flexible board 11, and so formed that the connector to the terminal 5 is formed of only the board 11. That is, a hole (h) having an area larger than that of a solder connector 16 is formed at the board 12. The terminal 5 electrically couples a connector housing 3 to wirings on the board 11 by solder connector 16. If a thermal strain due to self-generated heat or environmental temperature change occurs, a thermal stress is applied to the vicinity of the connector 16, but it is alleviated by the deformation of the board 11.

Title: Electrode structure of thickness shear oscillator
Inventor: HIGASHICHI SEIJI
IPC: H03H9/19
Filed: 1978-06-16
Abstract: PURPOSE:To facilitate an easy mass production of the thickness shear crystal oscillator for the ultra-high accuracy wacth by limiting the overflow of the solder to a fixed amount for the oblong thickness shear oscillator. CONSTITUTION:Lead electrode 6 is drawn out along end face 3 first from support electrode 5a provided to the main end face part and end face 3 each of oblong thickness shear oscillator 1 and then bent almost right-angled to be connected to exciting main electrode 4. Owing to such structure of the electrode, the solder can be prevented from flowing to the center direction of main face 1 of oscillator 1 due to the wetting performance of the solder, thus preventing the flow toward the solder. As a result, the solder overflow can be kept nearly constant at the main face end part.

Title: 3-d shape measuring apparatus
Inventor: UEDA TOSHITSUGU
IPC: G01B9/02
Filed: 1986-03-31
Abstract: PURPOSE:To enable the measurement of a length, high in the accuracy and resolution with a simple construction, by changing a delay in the phase of one or both of two lights so that the difference in the phase delay of the two lights will be always a fixed value on the interfering plane in an interference optical system. CONSTITUTION:A wave difference between two lights is changed by varying the driving frequency of an AO modulator AOM2 to change the delay in the phase of respective lights. An output signal Vbeta of a phase detection circuit PD1 corresponding to a difference in the phase delay between lights of two different wavelengths is fed back to a volt control oscillator VCO to control the oscillation frequency of the voltage control oscillator VCO so that the difference in the phase delay between the two lights will be a desired fixed value DELTAbeta. A computing circuit CON2 determines the distance to a plane OBJ to be measured from a relationship between a wavelength difference of lights corresponding to the driving frequency of the AO modulator AOM2 and the current set phase difference DELTAbeta. Thus, the shape of an object to be measured can be measures accurately by gauging the drive value (X, Y) at a section DR2 for driving the object being measured.
