IPC: C23C2/06
Filed: 1990-11-30
Abstract: PURPOSE:To produce a zinc alloy plated steel sheet excellent in press formability and electrodeposition coating property by subjecting a steel sheet to hot-dip galvanizing and to alloying and then exerting plating in an acid electroplated zinc coating bath containing specific amounts of silica grains and nitric acid ions. CONSTITUTION:A steel sheet is passed through a hot-dip galvanizing bath, by which a galvanizing layer is formed on the surface of the steel sheet. Subsequently, heating is applied to the steel sheet to alloy the above galvanizing layer and this steel sheet, by which an alloyed hot-dip iron-zinc alloy coating layer as a lower layer having prescribed coating weight is formed on the surface of the steel sheet. Then, electroplating is applied to this steel sheet by using an acid electroplated zinc coating bath of pH1-4.5 containing 0.1-10g/l of silica grains and 100-20000ppm of nitric acid ions. By the above procedure, a zinc-silica dispersion coating layer as an upper layer in which 0.01-2wt.% of silica grains are uniformly dispersed and coating weight is regulated to 1-10g/m<2> is formed on the above lower layer. By this method, the zinc alloy plated steel sheet excellent in press formability and electrodeposition coating property and having plural plating layers can be obtained.

Abstract: PURPOSE:To avoid malfunction due to reset failure by synchronizing a reset signal with an internal clock to reset surely an internal circuit as occasion demands when an internal reset circuit for resetting the prescribed internal circuit at the time of switching-on of power supply is provided. CONSTITUTION:A reset signal generating means is constituted of a first node whose potential changes as following the change of the potential of the power supply in response to the switching-on of the power supply and a means to generate the reset signal in response to an internal clock signal. Therefore, if the potential of the first node reaches the potential determined beforehand, the reset signal is generated always regardless of the rise-up rate of the potential of the power supply after the switching-on of the power supply. Further, if the reset signal is not generated from the reset signal generating means even after the switching-on of the power supply, since the potential of a second node is set at the potential required for resetting, a device never malfunctions. For this purpose, an internal reset circuit is constituted of an inverter 25 consisting of the serial connection of a capacitor C1 and an N-channel transistor Q1 and the serial connection of the N-channel Q3 and a P-channel Q4.

Title: Digital camera
Inventor: NAKAJIMA YASUMASA
IPC: H04N5/225
Filed: 1999-12-01
Abstract: PROBLEM TO BE SOLVED: To provide a digital camera simple in structure and, capable of reducing power consumption and failures in photographing. SOLUTION: When a lens cover 32 is mounted on the digital camera, the lens cover 32 moves a press contact ring 331 for pressing a press contact ring 331 into contact with a motion detection switch 332. Since the press contact ring 331 and the motion detection switch 332 are in a conducting state, a battery 81 of a power supply section 8 supplies power to an image pickup section of the digital camera 1. When a user forgets to remove the lens cover 32, since the power supply of the image pickup section of the digital camera 1 is not turned on, the user cannot execute photographing and the execution of photographing with the lens cover 32 left is not caused. Furthermore, since whether the lens cover 32 is mounted is detected by a press contact between the press contact ring 331 and the motion detecting switch 332, the structure is simple and power for detecting the mounting of the lens cover 32 is not required.
