A bifocal camera includes a first and second photographic optical systems which have focal lengths different from each other. A stationary mirror is arranged on the optical axis of the first optical system, and an exposure opening is positioned on the optical axis of the second optical system. A movable mirror is arranged to be movable between first and second positions. At the first position, the movable mirror interrupts incident light beams from the second optical system and guides incident light beams, which are passed through the first optical system and reflected by the stationary mirror, to the exposure opening. At the second position, the movable mirror interrupts the light beams reflected by the stationary mirror and allows the incident light beams form the second optical system to be made incident to the exposure opening. The movable mirror is shifted to the second position by a switching mechanism when a film is to be transferred along the exposure opening.

A fluid-filled elastic mount including an elastic body for connection of a first and a second member, a closure member secured to the second member and cooperating with at least the elastic body to define a fluid chamber filled with a non-compressible fluid, a device for dividing the fluid chamber into a first chamber on the side of the first member and a second chamber on the side of the second member, a device for defining a passage for restricted communication between the first and second chambers, and a device for accommodating a pressure difference between the first and second chambers. The elastic mount further includes an operating device which has a recess, divides the first chamber into a first section on the side of the first member, and a second section on the side of the partition device in which the recess is open, cooperates with an inner wall surface of the first chamber to define an annular restriction gap, and is elastically connected to the first member, a mass member of a predetermined mass located in the recess, a first elastic member for elastic connection between the mass member and the operating device, a first passage supported by the mass member for fluid communication between the recess and the second section, and a second passage supported by the operating device for fluid communication between the recess and the first section.

Apparatus for exposure control/focus adjustment for a camera comprises an exposure controlling mechanism, a focus adjusting mechanism and a source of rotary drive. The drive from the source is transmitted through a differential gearing to the exposure controlling mechanism and the focus adjusting mechanism. The differential gearing is operated such that the transmission of the drive to either one of the exposure controlling mechanism and the focus adjusting mechanism is blocked while allowing the other mechanism to be driven.

An image forming apparatus includes an image forming device, a sheet feeder, and a housing. The image forming device forms an image on a recording medium. The sheet feeder stores the recording medium and conveys the recording medium toward the image forming device. The housing accommodates an electrical device in the housing. The housing includes a housing body and a drawer that is drawn out from the housing body. The drawer includes a bottom plate on which the electrical device is placeable and a partition above the bottom plate on which the electrical device is placeable.

A power supply system for supplying a grid power to a building includes a power generator, a power storing device, and a power controller. The power generator generates off-grid power from a predetermined energy. The power storing device stores the grid power and the off-grid power and supplies the stored power to the building. The power controller controls consumptions of the grid power and the off-grid power. The power controller calculates predicted consumption data related to power consumed in the building and predicted generation data related to power generated by the power generator. The power controller calculates a charging-discharging schedule for the power storing device based on the predicted consumption data and the predicted generation data by formulating the charging-discharging schedule as a mixed integer programming problem.

A converging point of processing laser light is made to accurately follow a laser light irradiation surface of an object to be processed. An object to be processed 1 is irradiated with measuring laser light along a line to cut 5, astigmatism is added to a reflected light component of the measuring laser light reflected by a front face 3 of the object 1 irradiated with the measuring laser light, a displacement sensor signal corresponding to a converged light image of the reflected light component having the astigmatism added thereto is detected, and the displacement sensor signal is made to become a feedback reference value corresponding to the quantity of the reflected light component, so as to locate the converging point of the processing laser light at a predetermined position with respect to the front face 3. This allows tire converging point of the processing laser light to follow the front face 3 of the object 1 reliably and accurately even when an area exhibiting an extremely low reflectance to the measuring laser light exists in a part of the front face 3 and lowers the quantity of the reflected light component of the measuring laser light.

A laser processing method which can efficiently perform laser processing while minimizing the deviation of the converging point of a laser beam is provided.This laser processing method comprises a displacement acquiring step (S07 to S11) of irradiating an object to be processed with a rangefinding laser beam for measuring a displacement of a main surface of the object while converging the laser beam with a lens and acquiring the displacement of the main surface along a line to cut while detecting reflected light reflected by the main surface in response to the irradiation; and moves the processing objective lens and the object relative to each other along the main surface, while adjusting the gap between the processing objective lens and the surface according to the displacement acquired by the displacement acquiring step, thereby forming the modified region along the line to cut.
摘要:
There is offered a signal processing circuit for an electrostatic capacity type touch sensor capable of detecting a larger number of locations with a smaller number of touch pads as well as improving noise immunity. A selection circuit selects either a signal from a combination of the first and second kinds of touch pads outputted through the first and second output terminals CO1 and CO2 in a touch panel or a signal from a combination of the third and fourth kinds of touch pads outputted through the third and fourth output terminals CO3 and CO4. An electric charge amplifier outputs first and second output voltages V1 and V2 corresponding to a difference between capacitances of the touch pads on the touch panel based on the signals from the selected combination. A delta sigma type A/D converter converts the first and second output voltages V1 and V2 into digital signals.
