Abstract:
Provided is a vehicle speed control device with respect to which the speed at which a centrifugal brake operates can be easily changed from the outside without disassembling the device. A brake drum 11 is fixed to a vehicle body 101a. A brake shoe 23 rotates around a rotary shaft 20 of the wheel 101c, and reduces the rotation speed of the wheel 101c as a result of coming into contact with an inner circumferential side face of the brake drum 11. A spring 24 prevents contact between the brake drum 11 and the brake shoe 23 when the rotation speed of the wheel 101c is lower than or equal to a predetermined speed, and permits contact between the brake drum 11 and the brake shoe 23 when the rotation speed of the wheel 101c exceeds the predetermined speed. A position change mechanism 25 is installed within the brake drum 11, and changes the position of an end of the spring 24 on one end side. A transmission mechanism 26 transmits a force that is input by an external operation to the position change mechanism 25 and drives the position change mechanism.
Abstract:
A backlight includes a light source and one or more light recycling films. The light source generates light that exits the light source with an angular exit distribution. The light recycling films are oriented in relation to the light source so that the prism peaks of the recycling films are oriented away from the light source. The recycling films have a range of optimal incident angles that allow light to pass through the recycling films without recycling. The components of the light source, the characteristics of the recycling films, or both, are configured to control the overlap between the exit distribution of the light source and the optimal incident angle range of the recycling films.
Abstract:
In an emergency brake mechanism of the present invention, a rotation input shaft is increased in rotation speed by a planetary set-up gear to centrifuge weights. Through the action of the centrifugal force of the weights, linings of the brake shoes are brought into press-contact with a fixed portion to reduce rotation of the rotation input shaft, such that a large braking power is produced for a compact emergency brake mechanism.

Abstract:
A smoothing circuit is configured such that: a voltage between two voltages having been divided by voltage dividing resistors near a node to which an intermediate reference voltage is applied is further divided by buffers and voltage dividing resistors into intermediate voltages which are output as grayscale voltages, respectively. Also, a voltage between the voltage having been divided by the voltage dividing resistors and a voltage having been divided by the voltage dividing resistors, and a voltage between the voltage having been divided by the voltage dividing resistors and a voltage having been divided by the voltage dividing resistors are further divided, thereby generating intermediate voltages which are output as grayscale voltages and, respectively.
Abstract:
There are provided optical members having a microlens array structure that can be produced by a more simple process, as well as devices employing them. The optical members have on one main surface a microlens array formed using a replication process that employs a mold comprising a plurality of gas bubbles arranged on a replication surface. There are also provided devices that employ the optical members.
