摘要:
In a touch sensor, one ends of optical fibers are disposed at positions corresponding to respective pressure sensing points on a sensor sheet. The optical fibers in a bundled form are connected in a detection unit. The detection unit includes therein a camera that takes an image showing a change in luminance at the other ends of the optical fibers. A transmissive body is disposed to contain the other ends of the optical fibers and light sources. Upper and side faces of the transmissive body are covered with antireflection members. The transmissive body has substantially the same refractive index as the core of each optical fiber. A force applied to the sensor sheet is detected based on the change in luminance at the other ends of the optical fibers shown in the image taken by the camera.

The invention provides a railway car with superior riding quality by improving the flexural rigidity of the car body structure while suppressing increase of body structure mass. A reinforcing plate 7 is attached to a roof construction 1 on the side facing an inner side of the car body at a longitudinal center portion of a railway car body structure 10 composed of a roof construction 1, a side construction 2, an underframe 3 and an end construction 4. The range in which the reinforcing plate 7 is adhered in the longitudinal direction of the railway car body structure 10 is between two body bolsters 6, and the range in which the plate 7 is adhered in the horizontal direction of the roof construction 1 is approximately half the length of the roof construction 1 in the horizontal direction. The thickness of the reinforcing plate 7 is increased gradually as the height of the roof construction 1 in the vertical direction increases. According to this arrangement, the deformation of the roof construction 1 at the longitudinal center portion of the railway car body structure 10, which is excessive without the present arrangement, is suppressed, and the flexural rigidity of the railway car body structure 10 is effectively improved. In other words, the bending vibration of the railway car body in the vertical direction can be suppressed, and a superior riding quality is provided.
摘要:
A regulator for use with fuel cells, which is mounted in a pressure controller of a fuel cell system, has a first diaphragm flexible under the pressure of pilot air supplied as an oxidizing agent to a pilot chamber, a second diaphragm flexible under the pressure of a hydrogen-containing gas flowing through a fluid passage, and a rod connected to a valve head. The spring force of a first spring is set to a value greater than the spring force of a second spring. The regulator is of a normally closed type in which the valve head is seated on a valve seat when the pilot air is not supplied to the pilot chamber.

摘要:
A printing head which outputs an output from a sensor device provided for monitoring various condition of a printing head as digital data, and a printing apparatus using the printing head. The output from the device for detecting condition of the printing head, e.g., information indicative of a substrate temperature, a resistance value of an electrothermal transducer, an ON resistance value of a power transistor which drives the electrothermal transducer and the like is digitized on the substrate, and outputted as digital information to the outside. Further, the digital information is outputted by utilizing a clock signal and a latch signal used for transferring print data to the printing head. This does not increase the number of wires and the area of the substrate.

A plate-shaped composite material has a first member and a second member. The first member is an expanded metal formed of a metal plate. The coefficient of linear expansion of the metal plate is less than or equal to 8×10−6/degrees Celsius. The first member suppresses thermal expansion of the composite material. The coefficient of thermal conductivity of the second member is greater than or equal to 200 W/(m×K). The second member maintains the coefficient of thermal conductivity of the composite material. This structure provides a reliable coefficient of thermal conductivity and high strength. The structure is suitable for a cooling substrate on which electronic elements such as semiconductors are mounted.

The present invention can remove particles such as dust by flowing solvent gas such as CO2 through a line filter and eject it from a nozzle so as to be converted to solid particles or liquid droplets and eject to a workpiece to be cleaned so as to clean particles or organic materials. It is possible to make the solvent to a solid particle or liquid droplet by adjusting a gap between the nozzle and the workpiece to be cleaned; thus, it is possible to select the most preferable state according to the extent of the adhesion of organic material to the workpiece to be cleaned. Also, it is possible to remove particles such dust in the solvent by a line filter; thus, it is not necessary to use highly pure expensive solvent, and it is possible to reduce the running cost of the apparatus.
摘要:
Satisfactory restartability has not been obtained so far because the timing of opening an exhaust valve of a cylinder under expansion stroke is adjusted for improvement of startability and a valve adjusting mechanism is always controlled in the same manner regardless of the engine status at start. In the invention, control is performed to adjust the timing of closing an intake valve so that an effective compression ratio of a cylinder under compression stroke reduces. Also, the effective compression ratio of the compression stroke cylinder is decided based on a piston position at engine restart. By varying the intake valve closing timing in the expansion stroke cylinder to reduce the effective compression ratio depending on the engine status at restart, it is possible to lessen a load imposed on a starter when the engine is restarted, and to improve startability without complicating the engine system.
