IPC: G01F1/692
Filed: 1984-02-17
Abstract: PURPOSE:To reduce the cost with a higher massproducibility by forming a metal thin film as a heat generating body on the surface of an electrically insulating and heat resistant support to feed power thereto from an electrode connected to a lead. CONSTITUTION:Power is fed from outside through a lead 4 and an electrode 6 and applied to a platinum thin film 5 forming a heat generating body on the surface of an insulating and heat resistant support 7 to generate heat. A thermosensitive flow rate detector is so arranged that the heat transmission between the thin film 5 and a flowing fluid is converted into an electrical signal to detect the fluidization amount and flow velocity of the flowing fluid. The thin film 5 obtains a desired resistance value with a resistance adjustment by laser trimming while facilitating the formation of a high resistance element. Thus, both low and high resistance elements coincided in the temperature coefficient of resistance are jointly used and incorporated into a circuit bridge to realize a simple circuit and an accurate temperature correction thereby enabling a higher response.

Title: Parallel comparison type a/d converter
Inventor: IKEGAMI MASAKAZU
IPC: H03M1/36
Filed: 1988-02-09
Abstract: PURPOSE:To reduce the offset error of a comparator by applying layout to a power supply and a ground line so that the voltage drop of the power supply at the comparator and a voltage rise of a ground are made equal to each other. CONSTITUTION:The layout of power supply and ground line is provided in a way that the voltage drop of the power line caused by a wiring resistor of a CMOS chipper comparator 5 and the voltage rise of a ground line are made equal is provided. Thus, then the wire length from a pad to a branch point is nearly equal even in a comparator where power supply is supplied from the remotest branch point 7 from the power supply pad 1 and a GND level is supplied from the remotest branch point 8 from a GND pad 3, the voltage fluctuation of the power supply and the voltage fluctuation of the GND are nearly equal to each other, and the offset error of the comparator is decreased. Since a current is less in the voltage fluctuation in the longitudinal wire to the comparator from the branch point in comparison with the current flowing in the lateral wiring, the effect of the fluctuation on the offset error of the comparator is less.

Interference fringes generated by spectrally diffracting beams from the light source 14 by the wavelength tuning element 5 are detected, and a wavelength where the wavelength tuning element 5 can transmit is varied so that the interference fringes are brought to specified reference interference fringes. Consequently, a laser device is tuned with a predetermined laser oscillation wavelength by the wavelength tuning element 5 even during a period when laser oscillation is stopped. That is, a wavelength tuning element control mechanism 18 changes the angle, etc., of the wavelength tuning element 5 so that interference fringes, which are transmitted through the wavelength tuning element 5 and spectrally diffracted and generated, are conformed to fixed reference interference fringes corresponding to the laser oscillation wavelength after the interference fringes are detected by a photodetector 11, and controls the wavelength capable of being transmitted. A HeNe laser is used as the light source 14.

Title: Automatic position recognition of bonding pad
Inventor: GOTOU YUKIHIRO
IPC: G05D3/12
Filed: 1982-02-25
Abstract: PURPOSE:To recognize position of junction pad at a high speed with high accuracy by picking up semiconductor pellet with a photo-electric converter, detecting the peripheral portion of pellet through arithmetic operation of binarized signal, picking up the inside of detected region and then obtaining matching between such region and reference pattern. CONSTITUTION:The pellets 2 are picked up by an ITV camera 3, and the external side 5, pattern 6 and pad 7 are indicated in white while the other portions in black due to irregular reflection of irradiated light beam. These white and black signals are input to an apparatus 4 as the 2-level signal. When image information is respectively added 4 in both X and Y directions, it becomes maximum at the external side 5 and the edge 9 of region 8 is detected. Since accuracy of peripheries is made high in recent years, it can be used sufficiently for position recognition. When the reference pattern 10 stored precedingly is matched with a pick-up signal obtained from a camera 3 after the periphery 9 is detected, position of pad 7 on the pellet 2 for the reference pattern 10 can be recognized. At this time, since the surveying region 11 is limited only to a narrow area, alignment can be easily realized at a high speed with high accuracy.

Filed: 1986-02-15
Abstract: PURPOSE:To prevent the deterioration in the frequency characteristic even with high power excited by arranging the minimum length of an active electrode finger of a weighted interdigital electrode so as to allow it to come most inside. CONSTITUTION:Two sets of weighted interdigital electrodes 2 are arranged to a piezoelectric substrate 1 at a prescribed interval.

In applying an electric signal to the electrode 2, a surface wave of a prescribed frequency is excited. Then the electrode finger 21 comparatively longer is arranged at a part subject to less distortion, then a voltage caused in the substrate 1 is low and the joule heat is comparatively small. Thus, the deterioration in the frequency characteristic is prevented even when the resonator is excited by a high power.
