IPC: H02P3/12
Filed: 1980-07-22
Abstract: PURPOSE:To lessen effectively no-character intervals as well as to save current consumption dynamic braking a driving motor in a printer on stopping it. CONSTITUTION:A capacitor C is charged up to a fixed voltage during application of a Motor-ON signal. With a Motor OFF signal supplied, transistors T1 and T2 in a drive transistor circuit go to OFF. Through cut off of the transistor T1, the conduction between the negative pole of a supply source 12 and the base of a transistor T3 of a short, circuit transistor circuit is cut off, so that a base current is supplied to transistors T3 and T4 from the capacitor C via a resistor R2 to switch on T3 and T4. Because at this moment an enough base current IB flows from the supply source 12 to T4 via a resistor R3 and transistor T3, the transistor T4 is fully saturated, a motor 10 stops quickly by short-circuit of the armature circuit.

Abstract: PURPOSE:To simplify the circuit and to improve the reliability of failure detection, by obtaining current difference flowing to the 1st and 2nd motor and deenergizing both the motors when the difference is greater than a reference value. CONSTITUTION:Currents IM1 and IM2 flowing to motors 4 and 5 are inputted to an adder 23, the difference is outputted and compared with a reference value (c) at a comparator 24. When a driving circuit 1 is normal, the difference of torque of the motors 4 and 5 is 2Tp, the output of the comparator 24 is turned off, and a relay 20 is inoperative.

Title: Microphone unit, voice identifying device and method
Inventor: UIRIAMU ESU MEISERU
IPC: G10L11/00
Filed: 1984-05-18
Abstract: A plurality of microphones are disposed on a body to detect the speech of a speaker. First, second and third microphones may respectively detect the sounds emanating from the speaker's mouth, nose and throat and produce signals representing such sounds. A fourth microphone may detect the fricative and plosive sounds emanating from the speaker's mouth and produce signals representing such sounds. The signals from the different microphones are compared to allow the disciimination of certain speech sounds. For example, a high amplitude of the signal from the nose microphone relative to that from the mouth microphone indicates that nasal sound such as m, n, or ng was spoken. Identifying signals are provided to the speech recognition system to aid in identifying the speech sounds at each instance. The identifying signals can also select a microphone whose signal can be passed on to the recognition system in its entirety. Signals may also be provided to identify that spoken words such as "paragraph" or "comma" are actually directions controlling the form, rather than the content, of the speech by the speaker. The seiected signals, the identifying or classifying signals and the signals representing directions may be recovered by the system of this invention. The selected and identifying signals may be processed to detect syllables of speech and the syllables may be classified into phrases or sentences. The result may then be converted to a printed form representing the speech or utilized in the operation of another device.

Filed: 1983-06-08
Abstract: PURPOSE:To obtain a high-performance bowl-shaped molding by a method in which at the same time as air is blown into a parison from upper and lower parts, air is blown onto the inner surface of the parison from left and right sides. CONSTITUTION:Compressed air is blown into a parison 14 from above, and at the same time compressed air is blown onto the inner surface of the parison even from left and right sides. Also, even in the lower part of the inside of the parison, compressed air is blown into the parison upwards and also compressed air is blown onto the inner surface of the parison even from left and right sides. The parison can thus be maintained in a cylindrical form by air blowing without causing the bonding of the parison. While keeping the parison in the cylindrical form by preblowing of air utilizing such air curtain effects, a male mold 10 and a female mold 11 are closed and clamped. The contact bonding of the inner wall of the parison can thus be prevented in double wall portion without corners and corners of the parison. Also, the bonding of the parison can be prevented by evacuating air in the corners of the parison from the insides of the male and female molds 10 and 11 to vacuum.

Abstract: PURPOSE:To prevent contamination from occurring due to contact of an overlapped glued part of an envelope with a printing head and to perform accurate printing, by a method wherein when a discrimination signal is inputted where a printing paper is an envelope, the gap between a printing surface and the printing head is adjusted, and the printing speed of the head is lowered. CONSTITUTION:When an ENVELOPE mode is selected from printing modes of an operating part 23, a discrimination signal indicating that a printing paper is an envelope is outputted.

The printing speed is set to about 1/2 times the printing speed in the other printing mode, so that accurate printing free of misprinting can be performed even with the gap being set to the second distance D2.
