Title: Heater starting method for reflowing device
Inventor: TAKAHASHI HIRONOBU
IPC: B23K1/008
Filed: 1994-01-25
Abstract: PURPOSE:To reduce as much as possible the current required for startup of a reflowing device by staggering the startup time of each heater when the reflow device, in which a plurality of heaters are provided in a furnace body, is started up. CONSTITUTION:A heater 16 after the average current i1 of a heater 12 is attenuated, a heater 20 starts up after the average current i2 of the heater 16 is attenuated, and a heater 21 starts up after the average current i3 of the heater 20 is attenuated. As a result, the total current Z of the heaters 12, 16, 20 and 21 becomes smaller than the sum of the peak value of the average current i1 of the heater 12, the average current i2 of the heater 16, the average current i3 of the heater 20 and the average current i4 of the heater 21. Accordingly, the total current Z of the heater 12, 16, 20 and 21 does not exceed the prescribed current imax which is relatively small, and the situation such as decrease in power source and the like can be prevented.

Title: Differential amplifier circuit
Inventor: YAMAMOTO TAKESHI
IPC: H03F3/45
Filed: 1987-01-14
Abstract: PURPOSE:To obtain a differential amplifier circuit with less temperature drift and very small distortion by using a compensation circuit so as to add a signal current in opposite phase to a signal current flowing through 1st and 2nd transistors (TR) thereby canceling the currents and suppressing the nonlinear component due to a resistor connected to each emitter. CONSTITUTION:Suppose that a signal voltage is given between input terminals 11 and 12 and a current (i) flows to a TR Q5, then a signal current (-i) flows to a TR Q6. Since the base of TRs Q7, Q8 and Q2, Q4 is used in common and the bias current is equal to each other, the signal current (-i) equal to that of the TR Q6 flows to the TR Q8 and the signal current (i) equal to that of the TR Q5 flows to the TR Q7. Thus, the signal current flowing to the TRs Q3, Q1 is zero and the nonlinear item of the TRs Q1, Q3 due to emitter resistors RE1, RE2 is eliminated from equation with gm given thereto, and the temperature drift and distortion of the differential amplifier circuit of this constitution are halved.

Filed: 1990-01-17
Abstract: PURPOSE:To suppress drift or the like sufficiently and to attain correction even when jitter is large by generating a correction clock corrected to generate pulses of a desired number between scanning periods by a light beam. CONSTITUTION:A basic clock generating circuit 35 generates a basic clock CB of a clock frequency higher than the frequency corresponding to a sampling time interval from an A/D converter 26 by nearly one digit order and the clock is inputted to a correction clock generating circuit 34. The correction clock generating circuit 34 obtains how the same pulses between main scanning periods are obtained by interleaving how many pulses of the basic clock CB for each reflecting face based on each main scanning speed for each reflecting face of a rotary polygon mirror 19 inputted from a face synchronizing signal generating circuit 33 and the result is stored in the correction clock generating circuit 34. Thus, drift or the like is sufficiently suppressed and even when jitter is large, the jitter is sufficiently corrected.

Title: Micro volume flow apparatus for fluid containing solid material
Inventor: OGAWA AKIRA
IPC: F04B23/00
Filed: 1981-01-23
Abstract: PURPOSE:To accurately control flow volume of solution from a solution containing vessel for a long time by connecting a transparent cylinder to the vessel and controlling a very small flow of solution by a lifting speed of bubble discharged in the transparent cylinder. CONSTITUTION:A pump 30 is driven to equalize negative pressure inside a flow tube 31 and negative pressure inside a container 9 and then an air cock 13 is closed and a flow cock 16 is opened. Then, although solution inside the container 9 starts to flow out, solution cannot flow out since negative pressure in the flow side of the flow cock, namely a flow pipe 23 and negative pressure inside the container 9 are same. Afterward, when an air valve 2 is properly opened to suck in air via an air filter 1, air which has come out from a discharge port 8 into fluid inside a transparent cylinder 4 through a pipe 7 is lifted as bubble. Corresponding to the lifting speed of this bubble, solution flows out from the container 9. As the result, flow of solution can be perceived by watching a transparent pipe 25.

Title: Auto-resetting circuit
Inventor: FUKAZAWA SHOICHI
IPC: H03K17/22
Filed: 1988-01-18
Abstract: PURPOSE:To improve responsibility and to stabilize an action by setting the input level of an inverter with a resistance ratio having a satisfactory consistency to use a resistance for a supply voltage partial pressure and the threshold voltage of first fourth transistors. CONSTITUTION:Since resistances 21, 22 for partial pressure, NMOS 31 and 32 and PMOS 33 and 34 are used, the range of a supply voltage Vdd can be correctly set. Further, since the partial pressure ratio of the resistances 21 and 22 is not influenced by the temperature change, a voltage Vy of a connecting point Y is not also influenced for temperature and consequently, the NMOS 31 and 32 execute the stable action to the temperature change. By the partial pressure of the resistances 21 and 22, a resetting level can be freely selected. Since the capacitor is not used for the component, an integrated circuit operation can be easily executed, the response for the faster power source repeating change is satisfactory and an auto-resetting action is suitably executed for the change.
