Title: Soldering method for parts
Inventor: AOKI HARUMI
IPC: H05K3/34
Filed: 1981-05-18
Abstract: PURPOSE:To improve the reliability and productivity of soldering of electronic parts by disposing plural pieces of grooves which are finer in the peripheral directions than in the central direction of a soldering part, radially from the recess provided in a part mounting member and supplying molten solder from said recess along the grooves to the soldering part. CONSTITUTION:Ball solder 8 is placed in a recess 9 and is heated to allow molten solder 7 to advance along grooves 10, 12 by capillarity, so that the entire part of the solder is conducted in the circtuion of the grooves 10, 12. When the solder 7 arrives at a soldering part 1, it is similarly spread over the entire part of the soldering part by capillarity. Since the groove 10 in the central direction is made larger than the grooves 12 in the peripheral direction, the velocity v1 in the groove in the central part where the solder 7 flows is higher than the velocity v2 in the grooves 12 in the peripheral parts. As a result, air is expelled by spreading the solder 7 always from the central part to the outside parts and therefore the soldering part 11 can be soldered with extremely less voides despite its large area. Here, 1 in the figure denotes a power transistor, 3 a heat diffusion plate and 5 a heat radiation plate, respectively.

Title: Digital-analog converting circuit
Inventor: MASUDA KENZOU
IPC: H03M1/34
Filed: 1982-05-07
Abstract: PURPOSE:To decrease the power consumption when no A/D conversion is required and at the same time to prevent the generation of noises, by providing a time constant circuit to an input circuit to ensure a slow change of the D/A conversion output during a transition state of a switch 4. CONSTITUTION:A time constant circuit consisting of a resistance 9 and a capacitor 8 and a switch MISFET10 are provided at a part of the input of a current source switching D/A converter containing weight constant currnt sources 1-3 and switches 4-5 connected to the sources 1-3 respectively. When a control signal POFF is set at a low level, the D/A converter is set in an active state or a non-signal state. Then nodes N1 and N2 are set at values which are decided by bias voltage VB and a digital input respectively. When the signal POFF is changed to a high level, an FET10 is turned on to set the VB at a low level. In this case, the level of the node N1 is changed slowly by the time constant circuit. Then the output current iout of the D/A converter is reduced slowly down to zero from the amplitude center value iO. As a result, the generation of noises can be prevented for an amplifier which is connected to the output of a converter.

Title: Method of detecting adhesion of deposit
Inventor: NISHINO HARUHIKO
IPC: F02D45/00
Filed: 1998-03-24
Abstract: PROBLEM TO BE SOLVED: To detect adhesion of the deposit on the basis of a change of the idle open degree of a throttle valve and a change of the air-fuel ratio by detecting a change of the idle open degree of the throttle valve to an opening side and a change of the air-fuel ratio to a rich side. SOLUTION: During the idling operation of an air conditioner, whether the adhesion quantity DEPO computed by subtracting the initial idle open degree from the real idle open degree is larger than the value obtained by adding the predetermined value α to the former detected deposit correction open degree FDPOn-1 or not is judged (S43). Change of the throttle open degree at the time of idling operation is considered on the basis of this judgment. Continuously, whether an A/F feedback correction coefficient FAF, to which the feedback learning value KG is added, is smaller than the predetermined value β or not is judged (S44). In the case where the deposit is adhered, intake air quantity is reduced and the air-fuel ratio is lowered.  In the case where the correction coefficient FAF corrected so as to raise the air-fuel ratio is lower than the predetermined value β, lowering of the air-fuel ratio due to the adhesion of the deposit is judged.

IPC: F02D41/34
Filed: 1985-04-10
Abstract: PURPOSE:To eliminate wrong detecting of acceleration and deceleration in an engine and enable its fuel to be well increased and decreased, by discriminating the matching of a throttle sensor with the other sensor information as an acceleration and deceleration detecting means. CONSTITUTION:An electronic control unit 15 receives an input signal from a throttle sensor 16, detecting a rotary angle of a throttle valve 4, and an intake air flow sensor 19 measuring a flow of intake air. The control unit, discriminating by these sensors an engine to be accelerated when the unit simultaneously obtains inputs of an opening direction of the throttle valve 4 and an increasing direction of the flow of intake air while the engine to be decelerated when the unit simultaneously obtains inputs of a closing direction of the throttle valve 4 and a decreasing direction of the flow of intake air, corrects fuel to be increased and decreased. Accordingly, even if a wrong input is generated due to infiltration of dust and corrosion in a sliding part of the intake air flow sensor 19 or an interruptedly worsening contact in a wiring connector part, the control unit is prevented from wrong controlling the fuel to be increased and decreased because the flow of intake air is not changed in constant speed running.
