Title: Stabilizing circuit for high frequency amplifier
Inventor: MIKAMI SHIGENOBU
IPC: H03F1/08
Filed: 1992-08-25
Abstract: PURPOSE:To prevent the amplifying characteristics of an amplifier from getting adverse and to prevent the amplifier from being oscillated by parallelly resonating a parallel resonance circuit at the operating frequency of the amplifier and turning the stabilizing circuit to a high impedance. CONSTITUTION:Since a parallel resonance circuit 4 is parallelly resonated at the operating frequency of the microwave amplifier in a stablizing circuit 2, the admittance at the operating frequency of the microwave amplifier is turned to an A point on the Smith chart at the operating frequency of the microwave amplifier. Namely, the circuit 2 is turned to the high impedance by the resonance circuit 4 corresponding to the operating frequency of the microwave amplifier and does not affects the amplifying characteristics of the microwave amplifier. On the other hand, it is necessary to settle the admittance of the osicllating frequency of the microwave amplifier of the circuit 2 within a fixed conductance circle 20 required for stablization. Therefore, oscillation is prevented by setting the admittance of the oscillating frequency of the microwave amplifier within the conductance circle 20 required for stablization by using resistors R1 and R2.

Filed: 1999-08-10
Abstract: PROBLEM TO BE SOLVED: To enable a learner to diagnose by him-/herself the causes of an inability to catch speech and to effectively learn according to the causes, by converting a speaking speed of the speech synthesized from ordinary speech data and clear speech data without changing the speech characteristics. SOLUTION: In the 1st main matching, sentences are aurally outputted according to a speaking speed and narration set on a setting screen. Namely, the set narration is accessed by a storage part, and ordinary speech data or clear speech data corresponding to this narration is accessed by a speech data storage part 2 and outputted to a synthesized speech creating part 4. And, after a speech is synthesized by the synthesized speech creating part 4, a set speaking speed is read from a storage part, and when conversion of the speaking speed is necessary for outputting the speech at this speaking speed, the speaking speed is converted by a speaking speed conversion part 5, and then, the speech is outputted from a loudspeaker 7, and when the speaking speed conversion is not required, the speech is outputted from the loudspeaker 7 as it is.

IPC: B41J2/335
Filed: 1985-10-09
Abstract: PURPOSE:To improve the positional accuracy of an insulative substrate and a protrusion, to narrow the form of the protrusion to a uniform width, to increase its height and to obtain a thermal head which enables high-quality and uniform printing to be carried out by pouring sintering paste into a metal die consisting of a female die with a protrusion, heating an insulative substrate set in the metal die frame and manufacturing the protrusion after removing the insulative substrate. CONSTITUTION:A given quantity of glass paste is applied and dried inside a female die 4 obtained by processing and forming a narrow and tall protrusion with high precision. Next, a ceramic insulative substrate 1 is embedded into its die frame and is heated by a heating furnace 6 up to several hundreds of degree. The ceramic, receiving a glass content on heated, adheres to glass paste through reaction. However, it does not adhere to the female lower die 4, and a protrusion 3 is formed on the insulative substrate 1 by removing the substrate 1 from the female die 4. On this protrusion 3, a heating element and others are formed, thus enabling the manufacture of a thermal head to be realized. The form of this protrusion 3 depends on the accuracy of the female die, and the thermal head is uniformly manufactured without unevenness.

Title: Tension controller of tape
Inventor: IKENAGA AKISHIGE
IPC: G11B15/43
Filed: 1983-11-29
Abstract: PURPOSE:To keep the tension of a tape constant independently of variance of the winding diameter of the tape wound around a tape reel, by controlling rotation of the tape reel with expansion and contraction of an electrostrictive element. CONSTITUTION:When the tension of a magnetic tape 2 is increased or reduced, the contacting pressure of the tape to a tension post 5 is changed. Consequently, a tension arm 4 is turned, and the position of the tension post 5 is changed in accordance with this turning. This change is detected by a position sensor 15, and the output signal is fed back to a voltage applying device 18. The voltage applying device 18 controls the voltage applied to an electrostrictive element 17 in accordance with the detected position of the tension post. Consequently, the electrostrictive element 17 is expanded or contracted in the lengthwise direction in accordance with change of the position of the tension post to increase or reduce the pressing force of a pad 11 to a tape reel supporting part 13. Thus, the position of the tension post 5 is kept constant finally. It means that the tension of the magnetic tape is kept constant.
