Title: Piezoelectric oscillator
Inventor: AKAGAWA HIROAKI
IPC: H03B5/32
Filed: 1990-03-30
Abstract: PURPOSE:To keep stable oscillation by varying a power supply current supplied to an inverter in response to a control voltage so as to preclude the possibility of unstable oscillation or its stop even when the control voltage is low. CONSTITUTION:When a control voltage Vc is low, since a capacitance C of a variable capacitor 3 is increased, a negative resistance rho of the circuit is going to change in a decreasing direction. However, when the control voltage Vc is low, an amplified voltage obtained as an output of an amplifier 5-1 gets higher and a power supply current ICC supplied to a C-MOS inverter 1 is in creased. When the power supply current ICC supplied to the C-MOS inverter 1 is increased, the negative resistance rho of the circuit is increased. As a result, the change of the negative resistance rho in its decreasing direction as above is corrected. Thus, the stable oscillation is maintained even when the control voltage Vc is low.

Title: Semiconductor device with metal projection
Inventor: HATADA KENZOU
IPC: H01L21/60
Filed: 1979-07-04
Abstract: PURPOSE:To prevent an insulation film from cracking through pressuring during connection with an external lead wire by a constitution in which an electrode terminal region is not covered with an insulation film on it. CONSTITUTION:On a semiconductor substrate 21 an insulation film 24 is applied to protect a metal wiring pattern, and over an electrode terminal 23 of the wiring pattern a wider opening than the terminal 23 are formed. Next on this opening a barrier metal layer 26 which is wider than this opening is formed. Next over the layer 26 a metal projection 27 is selectively formed. Because there is not insulating film 24 between the projection 27 and the terminal 23 in this constitution, when connection between an external lead wire and the projection 27 is performed no cracking in the insulation film 24 due to deformation of the terminal 23 occurs.

IPC: H01L21/66
Filed: 1988-04-06
Abstract: PURPOSE:To enable measuring position precision of a color filter without being affected by hardware-wise characteristics, by directly data processing an element output. CONSTITUTION:An input signal is applied to a CCD area sensor 1 from an optical system equipment 2 and a driving circuit 4. Only the necessary part of element output of the sensor 1 is extracted as data, by using the timing signal received from a synchronizing signal generating circuit 4, and delivered to a data processing equipment, in which software-wise processing is executed. That is, the difference of color reproduction between a first field and a second field during interlaced scanning is calculated. This work is repeated by controlling the optical system equipment 2, and changing color and position on an image plane. Based on the data of the difference of color reproduction, position precision of the color filter is measured. Thereby the positioned precision of the color filter can be measured, without being affected by hardware-wise characteristics.
