摘要： A magnetic tape cassette comprises a compact reel lock mechanism which includes a pair of reel lock arms engaging with outer peripheries of a pair of tape reels, a sliding member serving as a cover for a single opening through which an end of an optical tape end detecting element is inserted into the cassette casing, a cam member which provided on the sliding member for rotating the pair of reel lock arms, and a guide member guiding said sliding member. When the tape cassette is out of a recording and/or reproducing apparatus, the single opening is closed by the sliding member and the reel lock arms restrict rotation of reels. Conversely, when the tape cassette is inserted into the recording and/or reproducing apparatus, the sliding member is pushed up by the end of the optical detecting element and as a result the cam member moves upward along with said sliding member. The opening, therefore, becomes open, and simultaneously the cam member releases engagement between the reel lock arms and the peripheries of tape reels.
摘要翻译：一种磁带盒包括一个紧凑的卷轴锁定机构，该机构包括与一对磁带盘的外周啮合的一对卷轴锁定臂，用作单个开口的盖子的滑动部件，通过该滑动部件检测光带端部的一端元件插入盒壳体中，设置在用于使一对卷轴锁定臂旋转的滑动构件上的凸轮构件和引导所述滑动构件的引导构件。当磁带盒离开记录和/或再现装置时，单个开口由滑动构件封闭，并且卷轴锁定臂限制卷轴的旋转。相反，当磁带盒插入记录和/或重放装置时，滑动件被光学检测元件的一端向上推，结果凸轮件随着滑动件向上移动。因此，开口变得开放，同时凸轮构件释放卷轴锁定臂与磁带卷轴的周边之间的接合。

摘要： When a command frequency to a rotating electric machine is included in an inverter lock frequency band, a frequency switching section switches the command frequency to a frequency outside the inverter lock frequency band by changing a slip frequency command value. In response to this, a torque command change section changes a torque command to a second rotating electric machine other than a first rotating electric machine of which the slip frequency is changed such that a torque fluctuation caused by the change of the slip frequency command value is canceled out.

摘要： A control device for an induction motor that drives a vehicle includes an electronic control unit. The electronic control unit i) controls torque of the induction motor when an inverter that controls supply of electric current to the induction motor is in a locked state, so as to release the inverter from the locked state, ii) determines whether the inverter is in the locked state, iii) controls a slip frequency of the induction motor when it determines that the inverter is in the locked state, and iv) superimposes a frequency that actual torque does not substantially respond, on the slip frequency, so that an electric frequency lies in a region outside a lock region in which the inverter is in the locked state.

摘要： Each lock portion (15) has a front portion (23) including an anchoring pawl (24) and a back portion (25) extending in a direction opposite to the front portion. Therefore, when a slider (14) withdraws, each back portion comes into contact with the inside surface of a back wall (10) of a cassette shell (4) and each lock portion rotates in an unlocking direction. A bottom surface (109) defining each recess between engaging teeth (107) has a central portion which protrudes in a chevron shape. A corner of each protrusion has tapered surfaces (110′) and (110″). An anchoring pawl of each lock portion has a flat surface that comes into contact with one inclined surface (109′) of a chevron-shaped portion of any one of the recesses and one tapered surface (110′) of a protrusion disposed behind the adjacent recess.

摘要： A multinozzle ink jet recording device having a dense arrangement and a method of producing the same are disclosed. Two electrodes for applying a voltage to the side walls of a piezoelectric plate lie in the range of a pressure chamber, so that an electric field is prevented from acting on portions which do not contribute to the ejection of an ink drop. This obviates the waste of voltage and thereby realizes low voltage drive which reduce the size of the pressure chamber. All the grooves serve as pressure chambers without any slit or similar wasteful space intervening between them. Thus the multinozzle print head has a dense configuration. With such a print head, the recording device achieves a miniature and compact arrangement.

摘要： An apparatus for driving an ink-jet recording head includes a piezoelectric device, a drive waveform generation circuit, a waveform extraction circuit. The drive waveform generation circuit generates a drive waveform in which n basic waveforms are connected in series, each of the n basic waveforms having a single period, where n is an integer equal to or greater than 2. The waveform extraction circuit which extracts m (m is an integer, and 0≦m≦n) of the n basic waveforms as a print drive waveform based on an externally supplied print data, and applies the print drive waveform to the piezoelectric device. Thereby, an ink is discharged from a nozzle based on a distortion of the piezoelectric device.
