Abstract:
A flashlight control apparatus having a device for emitting flashlight towards a subject and a device for receiving the light reflected from the subject through a photographing lens. An output is generated which corresponds to the received light which is time-integrated in order to calculate the amount of light received. An optimum integration level is calculated which is to be integrated. This optimum integration level corresponds to an optimum quantity of flashlight to be emitted by the emitting means, based on film speed information. A time limit is also calculated, which is shorter, by a predetermined length of time, than an optimum emission time of the emitting device. This optimum emission time is based on aperture value information and object distance information. The emitting device is controlled to stop emitting flashlight when the time limit elapses, in the case where a quantity of light received by the light receiving devices has reached an optimum quantity before the time limit elapses.
Abstract:
The present invention has as its object to detect the termination of ink reliably and highly accurately in an ink jet recording apparatus. An ink cartridge 2 has an opening 5 for connection to a recording head 1, and is comprised of a negative pressure generating member containing portion 14 containing a negative pressure generating member 13 and having an atmosphere communicating port 10, and an ink containing portion 16 which is adjacent to the negative pressure generating member containing portion 14 and communicates therewith at the bottom 11 of the ink cartridge. Ink detecting means 3 is provided below the ink containing portion 16. When the detecting means 3 detects a reduction in the remain in the ink containing portion 16, ink remains only in the negative pressure generating member containing portion 14 and the remainder can be substantially estimated. For the remaining ink, the amount of use is calculated by the counting of discharge pulses or the like and is compared, whereby the remain of the ink can be detected accurately and easily.
Abstract:
The invention provides a method and apparatus for manufacturing a liquid container having an enclosed space within an inner wall of the liquid container, the enclosed space filled with a plurality of porous members. The plurality of porous members include a plurality of inner porous members and a plurality of outer porous members. The method includes the step of packing the porous members into the enclosed space so that the inner porous members only contact and press against other inner porous members and/or outer porous members, and the outer porous members contact and press against the inner porous members and the inner wall of the liquid container. The method also comprises a step of compressing the porous members. The apparatus has compressing means for compressing the porous members and packing means for packing the porous members into the liquid container. The invention aims to reduce an amount of non-dischargeable liquid contained by the liquid container by packing porous members into the liquid container with a desired compression distribution. The invention also aims to allow the same kind of porous members to be suitably packed into containers that store liquids having different surface tensions, or containers having different capacities or shapes.
Abstract:
A device for controlling a partial number of engine cylinders employs a geneva movement, intake-air-cutoff valves, an exhaust-gas-cutoff valve and a DC motor. The geneva movement divides the driving force of the DC motor into two: a force intermittently driving the intake-air-cutoff valves and a force driving the exhaust-gas-cutoff valve, so that the exhaust-gas-cutoff valve cannot open until the intake-air-cutoff valve has closed when the engine operation is changed over to a partial-cylinder-operation mode, and the intake-air-cutoff valve cannot open until the exhaust-gas-cutoff valve has closed when the engine operation is changed over to the full-cylinder-operation mode. As a result, time required for changeover of the engine operation between the full-cylinder operation and the partial-cylinder operation is minnimized and additional driving unit is omitted.
Abstract:
In a color changing lamp equipped with a bulb 4 emitting a color of light, a glove with a different color from the color is selectively located on the covering position and exposure position of the bulb 4 in order to emit the different color of light. The current supply for the bulb 4 is stopped while the glove is selectively moved, thereby preventing different colors of light in a mixed state from being emitted on the way of exchange.
Abstract:
An ink jet recording head unit for performing a recording operation by discharging ink is desclosed. The ink jet recording head unit includes an ink jet head portion having an ink passage communicated with a discharge port for discharging ink and a substrate having an energy generating element for causing energy for discharging ink to act on ink present in the ink passage, the ink being supplied through an ink receiving port of a connecting portion; and an ink supply member having a connecting portion to be connected to the ink jet head portion so as to supply ink to the ink jet head portion via the connecting portion. At least one of the connecting portion of the ink jet head portion and the connecting portion of the ink supply member has a projection portion at a position at which it comes in contact with the corresponding connection port so that one connecting portion is respectively connected to a corresponding connecting portion by deforming and bringing the projection portion into contact with the connecting portions.
Abstract:
A speed controller includes a drive source, an input device for inputting the driving speed information of the drive source, a driver for driving the drive source on the basis of the driving speed information input by the input device, a detector for linearly detecting the amount of movement of the drive source, an output device for outputting movement amount information obtained by the detector, and a corrector for correcting the driving speed information by the use of the movement amount information obtained by the detector, the corretor imparting new driving speed information as the corrected value to the driver.
Abstract:
The invention provides a method of bonding into an integral structure a unit formed by disposing therein a heating wire and a temperature detecting wire, a surface cloth material of an electric carpet to be manufactured, and an insulating material of the same, wherein a metallic foil is used in the unit, the metallic foil itself is caused to generate heat by electromagnetic induction, at least one heat-fuseable film layer is melted by the generated heat, and the carpet elements are integrally bonded by pressing. The method provides for efficient bonding as well as the elimination of pile-collapsing of the surface cloth material, thus producing electric carpets of high quality.
Abstract:
A camera and interchangeable lenses for such camera in which it is automatically detected whether or not the lens mounted on the camera has an automatic focusing capability. If it does, respective sets of electrical contacts provided on the lens and camera body are employed to transmit and receive a series of different data between the camera body and the lens. If it does not, the only a single datum is transmitted, for example, an open lens-stop value of the lens, is transmitted over the two sets of contacts. An automatic focusing actuation voltage applied from the camera body can be sensed to determine whether or not the lens has the automatic focusing capability.
