Filed: 1989-03-30
Abstract: PURPOSE:To mount a chip component by a much simpler process by a method wherein one part of a conduction pattern is formed on a pedestal and a bump for chip-component bonding use is formed. CONSTITUTION:A copper foil is pressure-bonded thermally onto a substrate 4A and a pedestal 21; after that, an etching treatment is executed; a dipole antenna 4B and a wiring pattern are formed from the substrate 4A to the surface 21A of the pedestal 21. During this process, the dipole antenna 4B and one part of the wiring pattern are formed up to a prescribed position on the upperside face 21A of the pedestal 21; this part protrudes from the surface of the substrate 4A by a thickness of the pedestal 21. A bump part 24 is formed as bumps 24A and 24B; these bumps are bonded to electrodes 16A and 16B of an opposite chip component 15. Thereby, it is possible to mount the chip component 15 on the substrate 4A by a simple process without using a bonding member such as a bump or the like.

IPC: B29C37/00
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To measure thickness unevenness of a film with high accuracy in a contactless state regardless of hardness by measuring the change of outline dimension of a film roll using an intercepted light measuring type dimension measuring means. SOLUTION: A film roll 1 is fixed in such a way that its roll axis is parallel to the reference face of a fitting base 2, and a light projecting part 3 and a light receiving part 4 are so constituted that the optical axes are parallel to the reference face of the fitting base 2. While maintaining this parallel relation, a moving base 5 can move in the direction of the roll axis of the film roll 1. While moving the moving base 5, the light quantity, intercepted by the ridgeline of the film roll 1, of light from the light projecting part 3 is measured by the light receiving part 4 to measure the change of outline dimension, that is, outer diameter dimension of the film roll 1 in a direction along the roll axis of the film roll 1. Detection of this dimensional change results in detecting thickness unevenness of a film.

Title: Water depth detecting circuit for electronic wrist watch
Inventor: MIYAZAWA OSAMU
IPC: G01C13/00
Filed: 1982-05-13
Abstract: PURPOSE:To obtain a water depth detecting circuit for an electronic wrist watch wherein an LCR oscillating method having excellent temperature characteristics is used in a simple constitution, and inductance which is varied with the water depth is detected by an LCR oscillator using a resistor having the temperature characteristics. CONSTITUTION:The gate voltages of an invertor 4 and a driver 5 are always the same, and internal resistances do not impart large effects to each other. When the temperature of the invertor 4 and the driver 5 increases, the oscillating frequency is increased. However, the resistance value of temperature compensating resistor 3 such as a thermistor having negative temperature characteristics is decreased and the resistance value of a detecting coil 1 is increased. Therefore the oscillating frequency is increased. As a result, the oscillating frequency change is offset as a whole. If the value of the temperature compensating resistor is made large to some extent, the effect of dispersion in resistance values of the invertor 4, the driver 5 and the detecting coil 1 can be alleviated and current consumption can be decreased.
