Abstract: PURPOSE:To make the utilization of a memory efficient without disturbing memory reception by printing out received information whose memory utilization efficiency is remarkably higher than the requirement of recording paper without storage in the memory. CONSTITUTION:A control circuit 38 stores received information in a memory circuit 22, displays, records or deletes the information, or measures the information quantity of the received information for each page and does not store the information to the circuit 22 when the quantity is more than a prescribed information quantity and the control circuit 38 gives a communication number and a page number to the information and directly prints out the result. Furthermore, a communication number and a page number are sequentially given to information and the resulting information is printed out from a page having highest information quantity among the information stored in the circuit 22 until the memory residual capacity reaches a prescribed quantity or over. Thus, even when the picture information with high information quantity is received, the memory is effectively utilized without disturbing the succeeding memory reception.

Abstract: PURPOSE:To improve the accuracy of a tracking distance by using only the phase of the largest FM modulation factor and reducing the time required for FM distance measurement to half, and generating a frequency discriminator and finding an accurate frequency. CONSTITUTION:A transmitter 1 sends out a sent wave of constant frequency and a sent wave after linear frequency modulation alternately for a prescribed period. A modulator 2 imposes pulse modulation upon the sent waves at a prescribed pulse repetitive frequency with prescribed pulse width. An antenna 3 amplifies the output of the modulator 2 to large electric power, radiates the output to space, and receives its reflected signal from a target. A receiver 4 converts the received signal outputted by the antenna 3 into a digital signal.

Title: Method for controlling of resistance welding
Inventor: NISHIZAWA KEIJI
IPC: B23K11/24
Filed: 1980-12-27
Abstract: PURPOSE: To perform good welding by setting the welding time sufficient for formation of min. nugget and keeping electric current flowing by the set time in spite of dropping of inter-electrode resistance down to a specified value when the diameter of the leading ends of electrodes is under-sized from a correct value.  
     CONSTITUTION: When the diameter of the leading ends of electrode is smaller than a correct value, a sufficient time is beforehand set so as to form min. nugget for preventing welding defects. For example, the set time is defined as (t 2 ) and at the time (t 1 ) when the drop rates ΔR, ΔV of inter-electrode resistance or inter-electrode voltage attain specified values, the welding current is conducted as it is without stopping and is stopped at the set time (t 2 ). This set time is set within the range where no splashes are formed. Thereby, the good welding is accomplished in spite of fluctuations at the leading ends of the electrodes.

Title: Method of starting fuel cell
Inventor: NISHIOKA MASATO
IPC: H01M8/04
Filed: 1984-09-06
Abstract: PURPOSE:To prevent any deterioration of the material of the electrode by preventing the open circuit voltage for checking the distribution of reaction gas from exceeding a given level. CONSTITUTION:When the temperature of a stack 1 reaches about 120-130 deg.C, current feeding to the heater is shut off and the stack 1 is then heated by battery reaction. Prior to heating the stack 1 by the heat of battery reaction, the open circuit voltage is measured to check the distribution condition of the reaction gas. Specifically, a fuel supply bulb 7 is opened and valves 8 and 9 for introducing an inactive gas such as nitrogen are opened to and nitrogen gas to the fuel gas and air supplied to the stack 1 thereby reducing hydrogen partial pressure in the fuel gas and oxygen partial pressure in the air. The thus produced reductions in hydrogen and oxygen partial pressures cause a decrease in the characteristic of each electrode thereby resulting in suppression of the open circuit voltage. Accordingly, it is possible to prevent any deterioration of the material of the electrode.
