Title: Production of steel plate electroplated on one side
Inventor: ASANO KAZUO
IPC: C25D7/06
Filed: 1985-03-26
Abstract: PURPOSE:To improve the appearance and chemical convertibility of a non- plating surface by conducting a steel plate which is thinly plated on the non- plating surface,with the non-plating surface as an anode, into a vertical type electrolytic cell and forming a passive film thereon while removing the thin plating therefrom. CONSTITUTION:The steel plate subjected to the thin plating for protection on the non-plating surface is conducted to a current conducting roll 12 and electricity is conducted to the roll to make positive the steel plate. Such steel plate is fed to the vertical type electrolytic cell 10. Liquid blowing nozzles 17, 18 are installed in the cell 10 to exert forcible convection to the plating liquid by a pump. The thin plating for protection on the non-plating surface is removed by the electrolytic effect from the non-plating surface of the steel plate and the passive film is formed thereon in the stage when the steel plate passes through the space between down pass side cathodes 15 and up pass side cathodes 16 as counter electrodes. The gaseous H2 generated from the counter electrodes 15, 16 and the gaseous O2 generated when the steel plate is passive generate the ascending flow by themselves and do not stagnate between the electrodes 15, 16 and the steel plate.

Title: Electron beam welding device
Inventor: YABUNAKA FUMIHARU
IPC: B23K15/00
Filed: 1982-04-12
Abstract: PURPOSE:To obtain the required current pattern of an electron beam without providing any divider and multiplier and to improve the linear characteristic of the rising and falling patterns of the current, by connecting a setter for current value on the output side of an integration circuit. CONSTITUTION:When a selector switch 27 is changed over while the current of an electron beam is off, an integration circuit 40 operates and an output voltage V2 rises with time. When the voltage V2 of an integration output terminal 51 tries to rise higher than the voltage +V0 of a reference power source 52 for setting an upper limit of a comparator 45, the output voltage of the comparator 45 moves in the direction of positive polarity and is fed back negatively so that the output voltage V2 of the terminal 51 is maintained at +V0. The rising time of the current of the electron beam can be set with the resistance value Ru of a rise setter 41. The falling time can be set with the resistance value RD of a fall setter 42. The current value of the setter for the current pattern of the electron beam is set by a current setter 24 consisting of a voltage varying circuit connected to the output side of the circuit 40 and the output of the setter for the current pattern is produced from a terminal 32. The rising or falling time of the current does not depend on the current set value.

Title: Air conditioner for vehicle
Inventor: TANAKA NORIYUKI
IPC: B60H1/32
Filed: 1980-05-13
Abstract: PURPOSE:To improve the rate of operation of a compressor by driving an air mix door in the direction of increasing warm air proportion on the way of adjusting a room temperature setting section of an air conditioner for vehicles to the high temperature side and also lowering the comparative temperature level of a thermostat. CONSTITUTION:When an adjusting lever 2 of a room temperature setting section 10 is adjusted to the high temperature side, comparative temperature level of a thermostat is progressively raised from the low temperature side to the intermediate position where an air mix door begins to be opened, and thereby the proportion of turning off a compressor is enlarged. From the intermediate position on, the comparative temperature level of the thermostat is lowered to reduce the turned-off proportion of the compressor. Thus, through the room temperature setting section 10 is set to the high temperature side, the compressor is driven by turning on a  switch 5 for sufficient dehumidification until temperature of a cooler is sufficiently lowered.

Title: Error detector
Inventor: IDE AKIFUMI
IPC: H04L25/497
Filed: 1986-03-20
Abstract: PURPOSE:To detect with a high probability whether or not an error exists by providing a maximum amplitude calculating device to calculate the maximum amplitude of an integrating value to integrate a detecting output and a pointer generating device to generate a pointer to show that an error exists when the calculated maximum amplitude exceeds the prescribed value. CONSTITUTION:When noise 32 is overlapped to a signal 29 impressed to an input terminal 1, a comparator 4 generates a pulse 35 by mistake. Thus, an 'or' circuit 5 also generates a pulse 37 by mistake and an erroneous detecting result 39 is sent from a D flip-flop 6. When the comparator 4 generates the erroneous pulse 35, at such a time, the changing quantity of the output of an integrating device 9 comes to be -1. As the result, since the output of the integrating device 9 is shifted by one level in the negative direction after the detecting error occurred, a waveform 45 is obtained. The waveform 45 is impressed to a maximum amplitude calculating device 10, a maximum amplitude 46 is calculated and the value comes to be 2. Since the numerical value exceeds 1, a pointer generating device 11 judges that the detecting error exists and a pointer is outputted through a pointer output terminal 12.
