Title: Message rate totalizing device
Inventor: KAWAMURA HIROSHI
IPC: H04M15/00
Filed: 1985-07-11
Abstract: PURPOSE:To process the message rate of the subscriber of an unmanned office without going to this office by metering and counting charging pulses independently of a call meter provided for each subscriber in a central office. CONSTITUTION:Charging pulses inputted from each of many input parts are sampled at a period shorter than the pulse width of charging pulses and the state is stored in a state storage part. If the contents of the state storage part are changed, an interrupt signal generating part generates an interrupt signal, and a reading means reads the contents of the state storage part by this interrupt signal. If read contents are changed from '0' to '1', an adding means adds '1' to contents in the address corresponding to a relevant subscriber in a main memory where the message rate for each subscriber is stored. Thus, the message rate of the subscriber of the unmanned office is processed without going to this office.

IPC: F16G1/00
Filed: 1986-06-30
Abstract: PURPOSE:To enable firm bonding of a tensile material with a rubber layer and to prevent the occurrence of peel therebetween, by a method wherein the tensile material buried in the longitudinal direction of a belt is a metallic twist wire or a metallic signal wire, and a belt body rubber layer is formed by using valucanized rubber in which tow is mixed. CONSTITUTION:Brass-plated tensile materials 4, each formed by applying brass plating on the surface of a steel cord, are buried in parallel in a rubber layer 2 along the longitudinal direction of a belt. Meanwhile, inorganic tow 5, e.g. metallic monofilament or glass tow, is mixed in the rubber layer 2, and the rubber layer 2 itself is formed with vulcanized rubber, prepared by adding sulfur in high unsaturated nitrile rubber. In manufacture of a V-belt 1, sulfur is added in rubber in which inorganic tow is mixed, after the tensile materials 4 are buried in rubber, the work is heated for vulcanization. In which case, copper atom in the plated layer of the tensile materials 4 is bounded in sulfur with sulfur, and since sulfur is a crosslinking agent, rubber molecules are bounded with each other. As a result, the tensile materials 4 are chemically firmly bounded with the rubber layer 2 through sulfur.

The coincidence of the timing for the irradiation of the X-rays and the movement of the line slits 3, 4 is obtd. in this way. The scattered X-rays are, therefore, effectively removed and the image faithfully reflecting the coefft. of absorption of the respective tissues of a human body are obtd.

Title: Heterostructure transistor
Inventor: NIKORASU JIEE MORU
IPC: H01L29/66
Filed: 1991-05-29
Abstract: PURPOSE: To provide a charge-injection transistor having a real-space electron- transfer hetero-structure with a superior high-frequency characteristic. CONSTITUTION: This transistor comprises a substrate 9, an Al0.3 Ga0.7 As buffer layer 4, an In0.25 Ga0.75 As channel layer 1, an Al0.1 Ga0.9 As barrier layer 5, a GaAs drift layer 6, a source electrode 2, a heater electrode 3 and a collector electrode 7. A voltage positive with respect to the source is applied to the collector and the heater. Electrons flow through the channel layer 1 and are heated. At a charging high temperature, the electrons surmount the barrier and enter the collector through the drift. By using InGaAs in the channel layer, a deeper quantum well for the conducted electrons is generated, which decreases leakage via the barrier at a room temperature. Further, the drift layer has a short transition period. The amount of leakage between the source and the collector is small, and the collector parasitic capacitance is low.  The frequency characteristic is double that of a conventional device.

Title: Stepdown switching power source circuit
Inventor: HOSOYA TATSUYA
IPC: H02M3/155
Filed: 1999-06-01
Abstract: PROBLEM TO BE SOLVED: To reduce loss in a step-down switching power source circuit which uses an N-type MOSFET as a switching element and has an overcurrent protecting circuit using a voltage drop due to on-resistance generated in the N-type MOSFET. SOLUTION: A switching element is constituted of an N-type MOSFET 11. A bootstrap circuit 15 generates a voltage which is to be applied to the gate of the N-type MOSFET. A control circuit 12 is provided with an overcurrent protecting circuit which detects a voltage drop due to an on- resistance of the MOSFET 11. When the detected voltage exceeds a first specified voltage, the protecting circuit gradually limits the on time of the MOSFET 11. When the detected voltage reaches a second voltage higher than the first voltage, the protective circuit makes the on time zero or sufficiently short. As a result, the loss of a stepdown switching power source circuit is reduced, and cost reduction and overheat protection of the switching element can be realized.
