A system having a machine having the function of reproducing an information recording medium, in which the system executes a program recorded on the recording medium by sending a machine actuating command signal to the machine by user actuation and by receiving signals from the machine. The system includes a main body portion of a machine, and a control unit for controlling the machine connected to the main body portion of the machine. The control unit has a housing, a plurality of control sections mounted on the housing actuated by the user with fingers, and a vibration motor mounted via a vibration motor mounting portion provided in the housing. The vibration motor includes a motor casing, a shaft rotatably supported by the motor casing, and an eccentric member mounted on the shaft. The eccentric member has a rotor and a plurality of coils mounted on the rotor which is mounted on the shaft. The vibration motor also includes a magnet mounted on the casing for facing the eccentric member, and a supplying member for supplying the driving current to each coil. The eccentric member is rotated when the driving current is supplied to each coil to cause vibrations of the vibration motor itself, with the vibrations being supplied via the housing to the user. This permits the vibrations to be felt by the user to make possible execution of the program excellent in simulated presence feeling.

A polarization separation device includes a first end surface on which incident light is incident, a polarization separation surface that reflects an s-polarized light component and transmits a p-polarized light component, a second end surface that is arranged to be opposed to the first end surface, converts the p-polarized light component transmitted through the polarization separation surface to the s-polarized light component, and reflects the converted light component to an optical axis direction which is the same as the incident light, a third end surface from which the s-polarized light component reflected by the polarization separation surface without transmitting through the polarization separation surface is output, and a fourth end surface that is arranged to be opposed to the third end surface and from which the s-polarized light component reflected by the second end surface and the polarization separation surface is output.

A light emitting device comprises: an LED chip mounted in a recess formed in a mounting substrate; a wavelength converting member that is disposed so as to cover the recess and the edge area around the recess and that is excited by light emitted from the LED chip to emit light of a wavelength different from an excitation wavelength; and an emission control member disposed at a light output side of the wavelength converting member so as to allow emission of light coming from an area of the wavelength converting member that corresponds to the recess and to prevent emission of light coming from an area of the wavelength converting member that corresponds to the edge area around the recess. This can prevent variations in color between light emitted from the central part of the wavelength converting member and light emitted from the part of the wavelength converting member that is located on the edge area around the recess of the mounting substrate, thereby reducing unevenness of color on the irradiation surface.

Disclosed herein is a battery cell configured to have a structure in which an electrode assembly including a separator disposed between a cathode and an anode is mounted in a battery case, wherein the battery case includes an upper case and a lower case, the upper case and / or the lower case being provided with a receiving part, in which the electrode assembly is mounted, the electrode assembly includes a plurality of electrodes or unit cells stacked in a height direction on the basis of a plane, two or more of the electrodes or the unit cells having different planar sizes, and the receiving part of the battery case is provided with stair-like steps corresponding to an external appearance of the electrode assembly.

An electronic device substrate is provided with a thin-plate core substrate; a metal electrode provided on the core substrate and electrically connected to an electrode of an electronic component to be packaged thereon; and an electrical insulation layer on which is mounted the electronic component, and which is provided to surround the metal electrode.

Disclosed is an imaging lens having a small F-number, high resolution, a sufficiently wide angle of view, and a small size.An imaging lens includes: a first lens with a meniscus shape having a concave surface facing an object side; a second positive lens; a third negative lens with a meniscus shape having a convex surface facing an image side; and a fourth lens having a convex surface facing the object side. The first to fourth lenses are arranged in this order from the object side. The imaging lens satisfies the following conditional expression:0.25<D / f<4.0(where D indicates the distance between the first lens and the second lens on the optical axis and f indicates the focal length of the entire system).
