Title: Measuring circuit for insulation resistance value
Inventor: HIRANO MASARU
IPC: G01R27/18
Filed: 1981-03-31
Abstract: PURPOSE:To enable measurement of an insulation value of each part of an electric system while discriminating the same, by providing a resistance circuit consisting of a plurality of serial resistors between a P-side circuit and an N-side circuit of a DC electric system and by providing a polarity discrimination circuit between the intermediate connection point of the resistance circuit and an earthing point. CONSTITUTION:A resistance circuit 5 wherein a resistor R1 and a resistor R2 are arranged serially is connected between a P-side circuit 1 and an N-side circuit of a DC electric system. Moreover, a polarity discrimination circuit 6 wherein rectifying elements 61 and 62 are connected in reversely parallel is connected to the intermediate connection point P of the resistance circuit 5 and an earthing point Q. Currents flowing through the aforesaid rectifying elements 61 and 62 are detected by current detection circuits 7 and 8 respectively. In these circuits 7 and 8, current detecting resistors R3 and R4 are connected to the elements 61 and 62 respectively and voltages v1 and v2 at both ends of these resistors R3 and R4 are detected by voltage detection circuits 72 and 82 respectively. Currents I1 and I2 flowing through the resistors R3 and R4 are operated by operation circuits 72 and 82 respectively. I1 and I2 thus obtained and a line voltage signal V between the circuits 1 and 2 are sent to an insulation resistance value operation circuit 10, which judges the presence or absence of inferior insulation in each part of the electric system and operates an insulation value thereof.

Title: Call regulation type idle line control method
Inventor: KAYAMA HIDETOSHI
IPC: H04B7/26
Filed: 1990-03-02
Abstract: PURPOSE:To always maintain the efficiency of a channel at its maximum and to stabilize a control channel by changing the number of mobile machines so as to access a base station in accordance with the variation of a traffic. CONSTITUTION:After checking whether an idle line signal 1-3 is informed in a down response channel 1-1 or its own machine does not correspond to a call-inhibited mobile machine specified by call regulation signals 1-9, 1-10, a mobile machine intending to access a base station transmits an access signal through an up control channel 1-2. If the access is failed due to a collision or the like, the signal is resent after the lapse of a previously set time. The sort of an access regulating signal is selected by the base station, but the number of mobile machines capable of accessing is changed in accordance with the variation of a traffic. Since the efficiency of the up control channel can be always maximized by controlling the traffic, the stable state of the channel can be maintained.

Title: Stabilizing method of density of copy image
Inventor: AOKI MINORU
IPC: G03G15/00
Filed: 1983-03-24
Abstract: PURPOSE:To prevent toner density from increasing abnormally and to stabilize image density by using a sensor pattern which has two constant image density values and specifying development characteristics themselves, and making an adjustment corresponding to the development characteristics. CONSTITUTION:The output of a photodetecting element 10 is converted by an A/D converter 11 into a digital signal, which is sampled by a control part. Consequently, three signals, i.e. a signal from some part of a photosensitive body 5 to which no toner sticks and signals corresponding to toner pattern density values corresponding to density values D1 and D2 of the sensor pattern 4 are obtained to know one point of the development characteristics and its gradient. The control part is stored with various development characeristics, which are applied selectively corresponding to an input. The selection result is contrasted with development characteristics 1-1 of standard toner density, and adjustments are made by the supplementation of toner, an increase or decrease in the electrostatically charged current value of the photosensitive body, etc. Then, no toner is supplemented at the time of abnormal development characteristics as shown by 1-4, so the toner density is prevented from increasing abnormally.
