Title: Voltage control quartz oscillator
Inventor: ADACHI KAZUO
IPC: H03B5/32
Filed: 1979-10-16
Abstract: PURPOSE:To secure the steady oscillation over a wide range of frequency, by using an LPF in the feedback circuit of the oscillator. CONSTITUTION:The reference voltage is fixed at a certain level with application of the control voltage V to the terminal (a). Thus the capacity of the variable capacity diode 2 is controlled. As a result, the resonance frequency is decided for the loop including the quartz oscillator 1, TTLNAND elements 3 and 4 plus LPF7 and 8, respectively. And then the frequency of the oscillator output O is controlled by the voltage V. In such constitution of circuit, an LPF consisting of the resistance R and the capacitor C is provided to the feeback circuit of the elements 3 and 4. Then the unsteady working width is reduced for the elements 3 and 4, thus reducing the waveform distortion at the points C and D. As a result, the unsteady state can be solved for the voltage control quartz oscillator to increase frequency variable range.

Title: Burner device
Inventor: TANAKA EIICHI
IPC: F23N5/10
Filed: 1985-06-20
Abstract: PURPOSE:To provide a positive combustion of a primary flame at a secondary flame hole under an abnormal condition, increase a difference in outputs under a normal condition of the primary flame detecting element and an abnormal condition of the primary flame detecting element and prevent an erroneous operation by a method wherein a primary flame sensing promoting member is arranged downstream of the primary flame sensing element. CONSTITUTION:Gas outputted from the nozzle 3 sucks air from the primary air hole 7, mixed in the inner pipe 2 and then forms a primary flame F1 at the primary flame hole 1. Since the primary flame hole 1 is restricted fro the secondary air with the outer pipe 6, the remaining non-ignited fuel forms a secondary flame F2 with the secondary flame hole 5 and the primary flame sensing promoting member 10 being applied as the flame base part together with the auxiliary air hole located at the outer pipe 6. Then, when an abnormal condition such as a lack of oxygen or the like, the primary flame F1 is moved outward of the outer pipe 6 while the flame is being eliminated. However, since the primary flame is ignited at the secondary flame hole 5 as a source of ignition of the primary flame sensing promoting member 10, the flame may not be contacted with the primary flame sensing element 9 and a difference between the case of normal condition and abnormal condition can be kept large.

IPC: H01L21/52
Filed: 1987-05-29
Abstract: PURPOSE:To prevent characteristic deterioration due to contamination, by sticking solder on a semiconductor piece and pressing this piece on a heated circuit substrate and at the same time by dissolving the solder stuck on a rear of the semiconductor piece and performing die-bonding of this piece on the circuit substrate so as to reduce generation of oxide. CONSTITUTION:A semiconductor piece 1 is attracted and held by the use of an attraction jig 3, and it is positioned on a solder ejection port 6 where solder 5 dissolved in a soldering container 4 is ejected. The piece 1 is moved transversally to bring its rear into contact with the solder 5. Then the solder 5 is stuck on the whole surface of a metallic film 2. The piece 1 is positioned on a heated circuit substrate 7, and it is slowly lowered to be pressed. The solder 5 of the piece 1 dissolves to perform die-bonding of the piece 1 on the substrate 7. Since the solder 5 then presses the piece 1 and dissolves at the same time, no oxide of the solder 5 is generated by heat. Characteristic deterioration due to contamination can be prevented accordingly.
