Title: Folding machine
Inventor: FUNAKOSHI AKIRA
IPC: B65H45/16
Filed: 1994-12-12
Abstract: PURPOSE: To make the dimension of folding steplessly settable by controlling a rotational speed and forward/reverse rotation of a stepping motor of driving a conveying table. CONSTITUTION: After the desired dimension of folding is set to a computer 7, a paper sheet P is fed into a feeder 4, and the paper sheet, passing between two fold in rollers 3, is fed onto a conveying belt 2. Since the conveying belt 2 is rotated in a fixed direction by a stepping motor 5, the paper sheet P is conveyed on a conveying table 1, to advance between the fold in rollers into contact with each other and the conveying belt 2. When the paper sheet P passing is detected, the computer 7 indicates a rotational speed of the stepping motor 5 so as to be matched with the preset dimension of folding. When the paper sheet P is conveyed to a prescribed distance, the stepping motor 5 is rotated, to generate sagging in the paper sheet P. This sagging is caught by a separate fold in roller 3 and press fitted between itself and the conveying belt 2, so as to fold the paper sheet.

Title: Position adjusting and fixing method for member
Inventor: ICHIHARA ATSUSHI
IPC: G02B6/42
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To prevent an adjusted positional relation from being shifted at the time of fixing. SOLUTION: After a positional relation between a rod lens 30 and a lens holder 22 is adjusted, a cylindrical part 34a of a guide body part 34 and a nose part 22a of the lens holder 22 are heated by a heater 40 as they are, so as to cure a thermosetting adhesive 52. The nose part 22a of the holder 22 is expanded by heating to be expanded to a Z-direction. Since a thermal expansion coefficient of the cylindrical part 34a of the body part 34 is set to be the same as the thermal expansion coefficient of the nose part 22a of the holder 22, an extended amount of the cylindrical part 34a of the body part 34 by heating is substantially the same as the extended amount of the nose part 22a of the holder 22. The rod lens 30 is prevented thereby from being pushed in a Z1-direction by a pressor plate 36 in a heating process.

IPC: F02B33/04
Filed: 1996-12-17
Abstract: PROBLEM TO BE SOLVED: To increase the charging efficiency of an air-fuel mixture into a cylinder by providing a residual air-fuel mixture discharging means discharging the residual air-fuel mixture remaining in a crank chamber after the air-fuel mixture primarily compressed in the crank chamber is fed into the cylinder. SOLUTION: When a piston 40 is lifted in the intake/compression stroke, an opening section 71 is opened, and the crank chamber 32 side of a cylinder and a storage tank 73 are communicated with each other via a residual air-fuel mixture discharge port 72. The residual air-fuel mixture remaining in the crank chamber 32 side passes through the residual air-fuel mixture discharge port 72 via the suction force of the suction pump 74 of a residual air-fuel mixture discharging means 70 and is stored in a storage tank 73. When the piston 40 is lowered in the explosion/scavenging stroke, the opening section 71 is closed at the skirt section 41 of the piston 40, and the connection between the crank chamber 32 side and the storage tank 73 is cut off.  The residual air-fuel mixture stored in the storage tank 73 is discharged to a cooling/circulating current means 80 by the suction pump 74, reduced in temperature by a heat exchanger 81, then returned to a suction passage 50.

Title: Image pickup device
Inventor: DOI HIROSHI
IPC: H04N5/335
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To relieve the phenomenon of being stroboscopic picture even when a moving subject is photographed by providing an image pick up means capable of a shutter operation, a delaying means which delays an output signal of the image pick up means for a prescribed period and an adding means which adds a 1st signal before being inputted to the delaying means and a 2nd signal outputted from the delaying means. SOLUTION: The signal outputted from a CCD 200 is converted into a digital signal by an A/D converting part 206 through an analog preprocessing part 205. A memory part 100 temporarily stores the digital signal, delays it by two field periods and outputs it. When a photographer selects a shutter operation here, a controlling part 103 commands a coefficient being α=0.5 to 1st and 2nd multiplying parts 101 and 102. An adding part 104 adds a signal delayed by two field periods and a signal having no delay on the same level and outputs them. Thus, it is possible to remain an after-image of a moving subject when a shutter is depressed.
