The company was founded by Nozomu Matsumoto in 1938 in Tokyo as a radio and speaker repair shop, and its current president is Susumu Kotani.Pioneer played a role in the development of interactive cable TV, the Laser Disc player, the first automotive Compact Disc player, the first detachable face car stereo, Supertuner technology, DVD and DVD recording, plasma display , and Organic LED display . The company works with optical disc and display technology and software products and is also a manufacturer. Sharp Corporation took a 14% stake in Pioneer in 2007, which has been reduced to 9%, but Sharp still remains the largest shareholder of Pioneer Corporation, followed by Honda Motor Co., Ltd. who owns roughly 4% of Pioneer shares following a memorandum between the two companies in 2010 to strengthen business ties.In March 2010, Pioneer stopped producing televisions, announced on 12 February 2009. On June 25, 2009, Sharp Corporation agreed to form a joint venture on their optical business to be called "Pioneer Digital Design and Manufacturing Corporation".In September 2014, Pioneer agreed to sell Pioneer Home Electronics to Onkyo.

In an organic electroluminescence device (100), a hole transport layer (22) is formed of a cured resin obtained by a ring opening polymerization of a polymerizable compound (a) containing a ring opening polymerizable group in the presence of a polymerization initiator (b). In addition, both of a maximum peak height Rp and a maximum valley depth Rv in an upper surface of the hole transport layer (22) are less than or equal to 14 nm. Accordingly, an organic electroluminescence device having excellent mass productivity and high luminescent efficiency is realized.

An object of the invention is to solve a problem that a cable exposed to an outside of a sound-emitting unit is tangled in fingers. In order to achieve the object, a headphone (1) includes: a sound-emitting unit (2) housing a speaker (48) having a diaphragm (49); and a cable unit (43) configured to transmit an electric signal to the speaker. The cable unit detachable from the sound-emitting unit is inserted in the sound-emitting unit from a bottom of the sound-emitting unit, disposed at an axially outer side than the diaphragm in a sound radiation direction of the diaphragm within the sound-emitting unit, and pulled from a top of the sound-emitting unit to an outside of the sound-emitting unit.


The merging support device is loaded on a movable body and acquires a current position of the movable body. The merging support device presents the recommended merging area when the movable body is on the merging lane. The recommended merging area is an area on the main lane where merging is recommended, and is preferably an area of a predetermined distance from an ending position of the merging lane.

A driving apparatus (101) is provided with: a first base part (110); a second base part (120); an elastic part (210) configured to couple the first base part with the second base part; and a driven part (400) supported by the second base part in a drivable aspect. According to such a driving apparatus, for example, if a driving force is applied to the first base part, the driving force is transmitted to the second base part via the elastic part. Thus, the driven part supported by the second base part can be preferably driven.

A light emitting element includes a flexible plate-like portion (100). The plate-like portion (100) includes a glass substrate (110), and an organic functional layer which is formed on one surface side of the glass substrate (110). The organic functional layer includes a light emitting layer. When the plate-like portion (100) is curved in a prescribed curving direction, and thus one surface (102) of the plate-like portion (100) is a concave surface, and the other surface (101) thereof is a convex surface, a surface which is positioned on the concave surface side among both surfaces of the glass substrate (110) is referred to as a first surface (111). The thickness of the glass substrate (110) is T. When the plate-like portion (100) is curved in a prescribed curving direction, and thus the one surface (102) of the plate-like portion (100) is a concave surface, and the other surface (101) thereof is a convex surface, a compressive stress is applied to a portion (a compressive stress generation portion 112) whose distance from the first surface (111) of the glass substrate (110) is less than or equal to L (L > T/2).
