Title: Vane pump
Inventor: NAGATA AKINOBU
IPC: F01C21/08
Filed: 1986-03-12
Abstract: PURPOSE:To make a vane can be projected certainly at the start of drive of a pump, by pushing-out the oil reserved in an oil-reservoir, into the back pressure chamber of the vane, at the start of drive of the pump. CONSTITUTION:When a pump is driven at the same time as driving an engine, an ignition switch 61 is closed, and a temperature switch 62 is also closed when the temperature of oil is low, for sending an electric current of a battery 60 to a coil 55. Then, a piston 54 is moved by the excitation force of the coil 55, for pushing-out the oil in an oil-reservoir 50. As viscosity of this pushed oil is high, this oil flows into a back pressure chamber 15b through a feed route 51 and ring grooves 34, 45, with high pressure. In this way, the high pressure of the oil in the back pressure chamber 15b, acts on the bottom of a vane 24, and consequently, the vane can be projected certainly even if it is at the start of drive of the pump.

Title: Color television picture receiver
Inventor: AKAZAWA SUSUMU
IPC: H04N5/57
Filed: 1980-04-24
Abstract: PURPOSE:To control the maximum value of beam current to prevent the entire screen from being darkened, by controlling the input level of a video signal only when the output of a wave detecting circuit is higher than the reference level. CONSTITUTION:The maximum value is detected among the demodulated color signals ER-EB by the transistors Q1-Q3. Each detection output is synthesized through a synthesizing circuit 60 as V.MAX (maximum value output)-V.MIN (minimum value output)=VI. The output VI receives a peak wave detection by a diode Dd and is compared at a comparator 90 with the reference voltage Vs produced from a pair of resistors Ra and Rb. The reverse current preventing diodes Dp and Db are turned on in case the output VI is larger than the voltage Vs, and thus the picture and luminance control circuits 110 and 120 are controlled to prevent an excessive beam current.

Abstract: PURPOSE:To shorten meter reading time by reading the indiscrete values of plural meter sensors connected to a repeating transmitting part simultaneously by the control circuit of this repeating transmitting part, and storing them in a memory, and afterwards, transmitting them to a central device at high speed. CONSTITUTION:The control part 3 of the central device 1 gives a signal to a channel switching part 8 according to a meter reading command from an operation part 5, and selects a channel to be meter-read. Afterwards, a meter reading instruction for each of n-pieces of the repeating transmitting parts is sent to the transmission line of this channel through a transmission reception circuit 6, a MODEM 6 and the channel switching part 8. Each repeating transmitting part connected to this transmission line fetches this telegram signal into the control circuit (CPU) 14 through the MODEM 11 and the transmission reception circuit 12, and gives a starting signal (starting voltage) simultaneously to all mXn-pieces of the meter sensors connected to that repeating transmitting part through an interface 16. When the starting signal is given, each meter sensor sends the stored indiscrete value, etc., to the repeating transmitting part by the telegram signal.

Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To provide a system and a method for transmitting electronic mail with which transmission information containing map information can be easily prepared as mail information and this information can be transmitted as electronic mail. SOLUTION: The user of a transmitter terminal acquires map image data at the desired spot by connecting the terminal to a map information providing system 20. Next, when handwriting is arbitrarily inputted onto the acquired map image data, the map image data with this handwriting input are prepared as new image data. Further, the user inputs any arbitrary document data. Afterwards, the transmitter terminal transmits the map image data with handwriting input and the document data to the mail server of a recipient as electronic mail information. Thus, the map image data, to which any arbitrary handwiring input is added by the user, can be transmitted as electronic mail together with ordinary document data.
