The present invention relates to a method for producing an n-type ZnTe system compound semiconductor single crystal having high carrier concentration and low resistivity, the ZnTe system compound semiconductor single crystal, and a semiconductor device produced by using the ZnTe system compound semiconductor as a base member. Concretely, a first dopant and a second dopant are co-doped into the ZnTe system compound semiconductor single crystal so that the number of atoms of the second dopant becomes smaller than the number of atoms of the first dopant, the first dopant being for controlling a conductivity type of the ZnTe system compound semiconductor to a first conductivity type, and the second dopant being for controlling the conductivity type to a second conductivity type different from the first conductivity type. By the present invention, a desired carrier concentration can be achieved with a doping amount smaller than in earlier technology, and crystallinity of the obtained crystal can be improved.

Disclosed is a vehicle body structure in which a front pillar, whose cross-section in a direction orthogonal to a longitudinal direction is a closed cross-section, is disposed at each of both vehicle transverse direction end portions of a vehicle cabin front portion such that a longitudinal direction of the front pillar runs along a vehicle up-down direction. A pillar garnish which covers the front pillar is provided at a vehicle cabin inner side of the front pillar. A reinforcing member, which extends in the vehicle up-down direction along the front pillar, is provided between the front pillar and the pillar garnish.

An ink follower which has stable followability regardless of a pen body specification, a flow rate for writing and a writing speed and does not cause back leaking of the ink originating in shortage in the ink follower in the middle of writing and scattering of the ink follower by impact applied to the pen body and which does not flow out from the ink reservoir in storing the pen body at a high temperature and provides a stable flow rate for writing. An ink follower is also provided which prevents the ink from volatilizing by shutting off the ink from the outside air (volatilization preventing property) and which prevents the ink from leaking in writing with the pen turned upward. The ink follower, for example, contains a non-volatile or slightly volatile organic solvent and a non-styrene base thermoplastic elastomer which is soluble or swollen in the organic solvent and showing viscoelasticity which is predominant in elastic response.

An electronic musical instrument enables a phrase that is stored as audio waveform data to be played back at an arbitrary tempo. The instrument includes an operator that allows the performer to change the readout position of the waveform data manually, enabling the performer to increase, decrease or reverse the speed of waveform data playback temporarily. Upon ceasing use of the operator, the playback of the waveform data returns to synchronization with the previously set tempo at a readout position that would be the current readout position had the operator not been used by the performer.

Disclosed is a bar feeder, which comprises a swing member designed to be swingably moved by a rotation shaft located above a guide rail. In normal mode, the swing member is kept in a standby in the vicinity of an upper position where the swing member is located to extend across and over a guide rail up to a bar rack The swing member normally rotated to a lower position where the swing member is located on a far side from the bar rack with respect to the guide rail. During the process, the swing member receives a bar from the bar rack, and loads the bar to the guide rail. When a bar is removed from the guide rail, the movement of a bar to the swing member is inhibited by an inhibition member, and the swing member without a bar is moved to the lower position to create an ejection space between the rotation shaft and the bar rack The present invention makes it possible to readily remove the bar loaded in the guide rail therefrom.
