Title: Feed current monitoring circuit of isdn terminal testing device
Inventor: TODA HIDEYUKI
IPC: H04M1/24
Filed: 1990-09-14
Abstract: PURPOSE:To easily monitor the feed current of not only a steady state but also a transient state by dividing a reference voltage for determining a monitoring upper limit value of the feed current into transient state use and steady state use, and also, controlling the monitoring timing. CONSTITUTION:A reference voltage generating part 6A always outputs a reference voltage 6AA and a reference voltage 6AB. A comparator 5F compares a feed current detecting voltage 5DA and the reference voltage 6AA, and when a feed current exceeds a monitoring upper limit value, it is outputted. A timing signal generating circuit 6H outputs monitoring timing signals 6HA, 6HB, after a test start signal 6G becomes 'H'. An AND gate 6C gates an output 5HA of a comparator 5H by the monitoring timing 6HA, and when the feed current exceeds the monitoring upper limit value in a transient state or a steady state, an OR gate 65 outputs it. In such a way, the feed current in a transient state and the feed current in a steady state are monitored, based on the upper limit value being suitable for each of them as a reference.

IPC: G06F3/048
Filed: 1986-10-15
Abstract: PURPOSE:To facilitate production of plural screen type display data by forming and storing the parts data for picture displaying data that is produced by dividing a picture horizontally in optional sizes. CONSTITUTION:The parts data 201-205 produced by dividing a picture into plural pieces in optional sizes are stored in a memory area 2 by a production means 1 and at the same time registered to a parts control table 3 for each data. A replacement means 7 replaces the fields of data 201-205 respectively. A production means 4 refers to the table 3 to read out the parts data needed by the area 2 and stores them into a memory area 5 with change given to the data contents. At the same time, the means 4 registers the parts data to a screen control table 6. Thus just a single process of production suffices with the picture type display data on a common parts among plural pictures. As a result, data can be easily produced.

Title: X-ray high-voltage device
Inventor: TAKANO HIROSHI
IPC: H05G1/12
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To lower the wave tail of tube voltage at a high speed, to prevent heating in a high-voltage part, by regenerating the energy of an electric charge, accumulated in a capacitor, from an X-ray tube to an A.C. voltage source or the other electric energy accumulating element, in a period for stopping X-ray radiation. SOLUTION: Turning on a semiconductor switch 21 applied tube voltage to the primary side (high-voltage side) of a second transformer 20, and the tube voltage is lowered in accordance with a turn ratio to be suppled to a rectifier 22. The rectifier 22 is conducted during the voltage, of the secondary coil (low-voltage side) of the secondary transformer 20, is higher than the voltage of a first capacitor 12, and a current flows. At that time, the nearly all energy of the electric charge, accumulated in a second capacitor 16, is regenerated in the first capacitor 12 on the input side of an inverter 13 via the second transformer 20. Resultantly, the tube voltage is suddenly dropped to sharply lower a wave tail on turning on the switch 21. Consequently, a harmful low- energy X-ray exposure can be reduced, thereby obtaining a miniature and high- efficient device.

Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To make a display of assigning intensity levels performable. SOLUTION: A chiral-smectic liquid crystal having a structure (intra-plane chevron structure) shown by the graph is utilized for a liquid crystal panel. This intra-plane chevron structure consists of a first region A1 wherein a layer normal direction 4 is inclined to one side (left side in the graph) to the direction R of uniaxially aligning treatment and a second region A2 wherein the layer normal direction 4 is inclined to the other side (right side in the graph) to the direction R of the uniaxially aligning treatment.

Title: Stabilized power source circuit
Inventor: WATABE SOICHI
IPC: G05F1/56
Filed: 1991-08-30
Abstract: PURPOSE:To simplify the constitution of a stabilized power source circuit, to suppress the heating of a stabilized transistor TR, and also to facilitate the resistance secured after a protecting operation by connecting a diode between a DC output line and the output part (collector of TR) of an error amplifier circuit with the former set at the cathode side and the latter set at the anode side respectively. CONSTITUTION:A diode 50 is connected between a DC output line 8 and the output part of an error amplifier circuit 34 with the former set at the cathode side and the latter set at the anode side respectively. Under such conditions, the potential difference is increased between the emitter and the collector of a stabilized TR 24 in both an input overvoltage state and an output overcurrent state. Then a control TR 28 is positively biased via the diode 50. Thus the emitter-base of the TR 24 is biased by the TR 28. Then the TR 24 is turned off and latched as it is. The restoration is secured after a protecting operation just with the second application of the input voltage.

Abstract: PURPOSE:To surely replace a developing device by relatively comparing a toner quantity inside the developing device when it is unused with the residual toner inside the developing device when it is used, and deciding the replacing period of the developing device. CONSTITUTION:The toner quantity at the initial stage of an unused developing device is stored in a storage means 14 via a detecting means 13, so that a signal vale from the storage means 14 is compared with the signal vale on the residual toner of the developing device from the detecting means 13 via a comparative means 15, to presume the toner quantity inside the developing device. Therefore, when the signal value from the detecting means 13 is fluctuated by a constant ratio compared with the signal value the storage means 14, the comparative means 15 issues a signal for replacing the developing device. Thus, the developing device having no toner can be surely replace to a new developing device.
