A resin composition containing: a thermoplastic resin; graphite; and a fibrous body, when the resin composition in a molten state is filled in a mold from a direction orthogonal to a thickness direction of a resulting resin molded article 1 and molded to obtain a resin molded article 1 of 100 mm in length×100 mm in width×2 mm in thickness, in a cross-section obtained by cutting the resin molded article 1 along a direction X parallel to a filling direction and a thickness direction Z, among regions 1A to 1E obtained by dividing the cross-section into five equal parts in the thickness direction Z, an average orientation angle (A) with respect to a plane direction of the graphite in at least one of the regions 1A and 1E on outermost layer sides being 15° or less, and an average orientation angle (B) with respect to the plane direction of the graphite in the central region 1C being 35° or more.

Abstract: An operating device has a pair of linear members (43, 44) made of a shape memory alloy and contracting axially due to heat generated by electrification and generating tension in the contracting direction, a drive lever (19) supported to pivot about a pivot shaft (19a), a pair of drive rods (33, 34) respectively connected to both sides of the drive lever (19) with the pivot shaft (19a) being disposed between the sides of the drive lever (19), and a power supply circuit for selectively electrifying the linear members (43, 44). One end of each of the linear members (43, 44) is fixed to a stationary member, and the other end is connected to each of the drive rods (33, 34).

Abstract: A magnetic tape wind-up device designed to wind up a magnetic tape, which is fed at a constant speed by a capstan and a pinch roller, around a reel is provided with a slip mechanism having a drive slip gear (1) driven by a motor to rotate and a driven slip gear (2) which is in frictional engagement with and is driven to rotate by the drive slip gear (1) while slipping therewith, thereby to drive the reel to rotate. This slip mechanism is configured to be capable of reducing the mean slip torque by periodically changing slip torque, thereby making it possible to wind up a tape cassette having a high rotational load without trouble.

Abstract: A cassette tape player has a cassette chamber defined therein adapted to be selectively opened and closed by a hingedly supported lid which is movable between open and closed positions. This cassette tape player includes a cassette holder movable between loading and operative positions about a holder hinge axis parallel to a lid hinge axis about which the lid pivots. The cassette holder includes a generally elongated holder base and holder arms rigidly connected at one end to respective opposite ends of the holder base so as to define a cassette receiving chamber. A cassette guide is movably secured to a portion of the lid opposite to the lid hinge axis for pivotal movement between retracted and protruding positions about a guide hinge axis parallel to the holder hinge axis and operable to guide a tape cassette into the cassette receiving chamber with opposite side portions of the tape cassette slidingly received by the holder arms when the lid is in the open position.

Abstract: A tape recorder includes a first position where an analog compact cassette and a digital tape cassette are installed and dismounted, and a second position where a magnetic tape is caused to run. The digital tape cassette has a shutter for covering front openings for inserting a magnetic head and pinch rollers when the cassette is not used and opened in the magnetic tape running direction or the opposite when the cassette is used. The digital tape cassette also includes a holder for allowing either cassette to reciprocate between the first position and the second position, and a shutter operating device for opening and closing the shutter. The holder is integrated with the shutter operating device.

Abstract: A tape cassette mount for receiving different types of tape cassettes in a tape cassette recorder has a shutter operating mechanism including an arm and a guide roller provided at an end of the arm. The guide roller rotates while sliding along a guide of the tape cassette, thereby sliding the shutter open. When a different type of tape cassette having no shutter is inserted, the arm is pressed and thus pivoted by the tape cassette to a retracting position without damaging the tape cassette or a magnetic tape.

Abstract: In a brushless motor formed from a plate type stator in which a driving coil is buried, and a rotor which opposes this stator, a cutout is formed in a portion where no driving coil of a stator exists and a pulley section is provided in the periphery of the shaft-through section of the rotor. The pulley section is inserted into the rotor shaft hole formed in the center of the stator, and a pulley belt wound on the pulley section is guided outside the motor via the cutout of the above-mentioned stator. That is, the brushless motor is of an ultra-thin type in which a pulley is housed within the thickness of a motor.

Abstract: Melody and chord tone data are read out from a melody RAM and a chord RAM under the control of address counters in a CPU, and are supplied to LSIs. The LSIs are controlled by the CPU for operation on a time division basis for a plurality of channels, so that a given melody and chord are simultaneously produced from a loudspeaker.

Abstract: A method for separating a charge transfer interactive substance from a liquid mixture containing such a substance, wherein the separation is conducted by means of a separating membrane made of a copolymer having charge transfer interactive groups.

Abstract: A keyboard type electronic musical instrument in which note data and duration data are read out from a memory in accordance with the progress of a musical piece, and a control circuit (CPU) turns on display devices provided for individual keys on a keyboard in response to note data, thus training a player to operate keys specified by the display devices. The control circuit counts each instance of noncoincidence between a key represented by the note data and an operated key on the keyboard, and obtains deviations between a key operation timing defined by duration data and the timing of key operation on the keyboard. After the end of a performance, the control circuit informs the player of the number of the mis-key operations or the accumulation of key operation timing deviations by means of the display devices. A number of display devices corresponding to the accuracy of the performance are lit.

Abstract: Melody information representing pitches and durations of tones is stored in a first area of a RAM whose addresses are designated by a first address counter of an address register. Performance information representing tone colors, vibrato, etc. is stored in a second area of the RAM whose addresses are designated by a second address counter of the address register, while the stored melody information is read out and reproduced. The melody information and performance information stored in the respective areas of the RAM are read out in associated relation with respect to one another, to be sounded from loudspeakers.

Abstract: The disclosure is directed to an improved cassette tape recorder which is arranged to have a small loss during the change-over in the running or travelling directions of a magnetic tape between a first direction, i.e. a forward direction, and a second direction, i.e. a reverse direction, and wherein only a small functioning stroke is required for actuating the magnetic heads.
