IPC: B60H1/22
Filed: 1993-04-07
Abstract: PURPOSE:To use a combustion type heater safely by heating blown air in a heater core, through which hot water heated outside a cabin by an electric heater is flown, to prevent repetition of high and low blowing air temperature even if in the environmental conditions under which heat load is small. CONSTITUTION:A hot water produced by heating water in an electric heat-water heat exchanger 21 with an electric heater 28 located outside a cabin is flown into a heater core 15 of a fuel engine driven car air conditioner in a hot air duct 20 by a hot water pump 22 to heat blown air. In cooling operation under which heat load is small, the blown air is heated gradually by hot water which has been flown into the heater core 15 and adjusted by an electric heater capacity adjusting device 29 because, at the starting, the blown air is over-cooled after it has reached an objective temperature. Thus there is no risk for crew to touch high tension because the electric heater 28 is located outside a cabin, repeated stoppage and operation of the compressor 1 can be prevented to use the minimum required power only.

Title: Solder plating device
Inventor: KOBAYASHI SHIGEKI
IPC: B23K3/06
Filed: 1987-03-31
Abstract: PURPOSE:To prevent the forming of the oxidized film of a solder and a bridge by erecting a guide wall at the opening part of a nozzle body. CONSTITUTION:A guide groove 16 is provided on the front side plate 12a of a nozzle body 12 and the guide wall 18 standing on a intervals (e) on one side face of the lead frame 1 transferred along the guide groove 16. When the lead frame 1 comes into the nozzle body 12, a molten solder is stuck on terminal part up to the vicinity of the root of a mold part 3 and a solder plating is executed. In this case, the liquid level of the solder is increased with the effect of a surface tension due to the gap (e) between the guide wall 18 and frame 1 being small. The solder plating onto the side face of the frame 1 is thus ensured and the solder flow at the opening 15 of the nozzle body 12 is flattened. Consequently the oxidized film of a solder and the formation of a bridge are prevented.

Title: Semiconductor device
IPC: H01L27/04
Filed: 1992-04-02
Abstract: PURPOSE:To eliminate operation offsets by arranging a pair of transistors such that parasitic resistance resulting from ion implantation occur in electrodes which are of the same circuit type. CONSTITUTION:A current flows to the earth wire from a power supply line VDD via transistors T1 and T3 when a load circuit is activated, and, likewise, a current flows to the earth wire from VDD via transistors T2 and T4. Both currents are substantially the same in magnitude. The magnitude of the current in the transistor T1 depends on a potential difference between VDD and DL, and the magnitude of the current in the transistor T2 depends on a potential difference between the VDD and a DLB. Meanwhile, an effective voltage between a gate and a source of the transistors T3 and T4 becomes a potential difference between a control signal CLK and the earth wire GND. An ON- resistance of the transistor T3 is the same as that of the transistor T4. Consequently, a voltage parasitic resistance between the gate and the source of each transistor has no effect, and no difference arises in a preset voltage used in a conventional device. Therefore, operation offsets can be eliminated.

Title: Detecting device of curve of long object
Inventor: ABE KENJI
IPC: G01B11/24
Filed: 1984-04-23
Abstract: PURPOSE:To detect rapidly and precisely a curve of a long object such as a semiconductor, by applying a light onto the long object so that the shadow thereof projected onto an image sensor becomes the mininum, by binary-coding picture element signals by the image sensor, and by subjecting the binary-coded signals to image processing. CONSTITUTION:A light is applied from a light source 2 onto a long object, e.g. a semiconductor lead 3, so that the shadow of the lead 3 projected onto an image sensor 1 becomes the minimum. When the shadow 7 of the lead 3 is projected on the light-receiving surface of the image sensor 1, detected waveforms are binary-coded by a signal storing unit 4. For instance, the level of a waveform l1 is coded to logic 0 and the level of a waveform l2 to logic 1. Next, the binary-coded signals thus obtained are inputted to a memory unit 5 and compared in an image processing unit 6 with a reference signal of a lead having no curve, which is stored beforehand. Since the light is applied to be received by the image sensor so that the shadow of the long object becomes the minimum, the number of required picture elements is small, and thus detection is performed at high speed and with excellent precision.
