Title: Automatic focus camera
Inventor: MURATA HARUHIKO
IPC: H04N5/232
Filed: 1989-09-29
Abstract: PURPOSE:To attain automatic focus with high focus accuracy even at low illuminance by inserting a high frequency cut-off filter cutting-off solid-state pattern noise from a solid-state image pickup element between the solid-state image pickup element and a focus evaluation value generating means. CONSTITUTION:An image pickup video signal outputted from an image pickup circuit 4 is amplified by a variable gain amplifier 21, inputted to a gain control circuit 22 so as to attain a reference level. When a gain control signal is larger than a prescribed value, a low illuminance state discrimination circuit 30 generates a low illuminance signal LOW as the low illuminance state and the signal is inputted to a focus evaluation generating circuit 35. The circuit 35 extracts only a luminance signal in the focus area by the operation of a synchronizing separator circuit and a gate control circuit and fixed pattern noise is eliminated from the luminance signal via an LPF. Thus, an offset component in the fixed pattern noise is not included during the focus evaluation and focusing is applied by the focus evaluation depending only on the picture contrast even at low illuminance.

Title: Reduction gear for sheet material
Inventor: OKU ISAMU
IPC: B65H29/22
Filed: 1984-12-05
Abstract: PURPOSE:To decelerate sheet velocity to the desired one with certainty even if it is fed at high speed, by pressing the sheet being fed with pinch rolls, while controlling a span of decelerating time by these pinch rolls. CONSTITUTION:At that point that a tip end of a sheet 20 on a feed line reaches both upper and lower pinch rolls 1 and 2, a chock 25 is situated in a bottom dead center position, and these pinch rolls 1 and 2 are opened in their gap wide. And, the pinch roll 2 rotates at peripheral velocity of the same V1 as a feed rate of the sheet 20. When a tail end of the sheet 20 is detected by a detector 2, the chock 25 moves from the bottom dead center to a top dead center by a motor, and the lower pinch roll 2 goes up to a position of 2', pinching the tail end of the sheet 20. And, with control of another motor, after pinching the sheet for the specified time long at peripheral velocity V2, this sheet is discharged to a piler at this velocity. Thus, the duration of speed reduction is controllable with motor control so that proper pinch time is secured and it is decelerated to the desired velocity.

Abstract: PROBLEM TO BE SOLVED: To make transit of an oil flow from a laminar flow to a turbulent flow and improve a heat transfer rate, by arranging a stud or baffle concentrically in a surface of an internal metal fixture opposed to face each other to a piston crown reverse surface, in a piston cooling the piston crown reverse surface by liquid. SOLUTION: In an oil-cooled piston of an internal combustion engine, an internal metal fixture 2 is interposed between a piston crown 1 and a piston rod 4, and a cooling passage 7 is formed between a reverse surface of the piston crown 1 and the internal metal fixture 2. Here, a stud 5 or baffle 6 is formed in concentric circular shape further to be mutually arranged in zigzag shape in a surface of the internal metal fixture 2 opposed to the cooling passage 7. In the case of arranging the baffle 6, its mounting angle is changed, so as to adjust strength of turbulence in an oil flow. By this constitution thus formed, cooling oil generates a flow meandering in a lateral or vertical direction, since mixing of the cooling oil is generated, cooling performance of the piston can be improved.

Abstract: PURPOSE:To improve the waveform of an input current by changing the maximum amplitude of an electric current flowing through a reactor during the period of a short circuit by a switching(SW) element in the manner of corresponding to the amplitude of an AC sine wave. CONSTITUTION:In the period when a switching element 10 becomes ON, DC power lines 8, 9 are short-circuited and the voltage Ed across the ends of the switching element 10 becomes zero.

In the OFF period, a short circuit by the switching element 10 is canceled, a first capacitor 11 is charged by the output voltage of a rectifier circuit 7, and the voltage Ec across the ends becomes gradually higher for the OFF period. The electric current Ia flowing through a reactor 6a by the ON-OFF of the switching element 10 is averaged by a low-pass filter 2 so that a current waveform at a power terminal Ia closely approximates a sine wave.
