Title: Voltage-controlled type variable frequency oscillator
Inventor: ADACHI KEIGO
IPC: H03L7/099
Filed: 1993-03-26
Abstract: PURPOSE:To make possible the electric trimming of the voltage-controlled variable frequency oscillator by applying a trimming voltage between the electrodes of a voltage-controlled variable frequency variable capacity element and varying the electrostatic capacity between the electrodes. CONSTITUTION:If a frequency control voltage Vcont which is applied to the voltage variable capacity element 12 for frequency control through an induction element 15 is changed, the electrostatic capacity of the element 12 varies and an oscillation part oscillates at the resonance frequency of a resonance part 4, so the output oscillation frequency can be controlled. Further, the voltage variable capacity element 16 for control range variation decreases in the electrostatic capacity between the electrodes when the voltage applied between the electrodes rises. For the purpose, the electrostatic capacity is varied by varying the trimming voltage Vt applied to the element 16 through the induction element 18 and then the capacity element in the resonance part 4 is varied for trimming, thereby varying the control range of the resonance frequency. Consequently, the electric trimming can exactly be performed if the oscillation is not carried out within a desired frequency range owing to variation in voltage Vcont.

Title: Combustion device
Inventor: ISHIGURO TOSHIYUKI
IPC: F23N5/24
Filed: 1984-05-07
Abstract: PURPOSE:To detect the deficiency of oxygen in a room and incomplete combustion and thereby to increase the safety and cleanness by a construction wherein a combustion cylinder is divided into a main combustion section and a subordinate combustion section and an oxygen concentration sensor in which separate external electrodes are integrated is provided in the vicinity of the subordinate combustion section. CONSTITUTION:The air-fuel ratio lambda in combustion of a pre-mixed gas in a subordinate combustion section B is set at about 1.2, while the value lambda in a main combustion section A is set at about 1.3-1.6, i.e. below an abnormality detection level C of an oxygen sensor 20. A part of a third air pipe 24 contributing to combustion reaction, the value lambda of the subordinate combustion section B1 transfers onto a higher side of B1. An oxygen concentration in which the main combustion section A exceeds the abnormality detection level C is about 16-13% when lambda is 1.3-1.6, while the oxygen concentration in the subordinate combustion section B is about 18% when lambda is 1.2. Therefore, when an internal electrode (a) of the oxygen concentration sensor 20 is disposed on the side of the subordinate combustion section B and a subordinate air chamber 23 and an internal electrode (b) thereof on the side of the main combustion section A, there occurs a difference in an electromotive force between them, and thus it turns possible to detect the deficiency of oxygen and incomplete combustion, to curb the generation of carbon monoxide, to limit the oxygen concentration detection level to about 18%, and consequently to increase the safety and cleanness.

Title: Control circuit of loudspeaker input
Inventor: HIROSE SHINTAROU
IPC: H04R3/00
Filed: 1981-06-12
Abstract: PURPOSE:To increase the woof reproducing range and at the same time to suppress the increase of the Q value which is due to the feedback, by integrating the output of an HPF by an integrator and then applying the outputs of the HPF and the integrator to the input of one side of a comparator. CONSTITUTION:The output Vo is applied to an HPF2, and the HPF2 has the same characteristics as a loudspeaker connected to an amplifier 1. The output of the HPF2 is applied to an integrator 4, and at the same time the outputs of the HPF2 and the integrator 4 are applied to the input of one side of a comparator 3 to be compared with the input Vi of the amplifier 1 which is applied to the other input of the comparator 3. The output of comparison of the comparator 3 is fed back to the amplifier 1. In such constitution, the Q value is kept substantially equal to the Q value of the speaker itself regardless of an increment of the feedback degree by selecting a proper ratio between the low band resonance frequency and the output of the integrator. As a result, the woof reproducing range is increased, and at the same time the increment of the Q value which is due to the feedback can be reduced.
