Title: Mobile communication system and exchange control station
Inventor: OTERU YOICHI
IPC: H04Q7/36
Filed: 1990-02-20
Abstract: PURPOSE:To eliminate the overhead of processing of a switching control station accompanied with the change of a radio base station and that of communication between the switching control station and the base radio station by using a communication identifier assigned to communication to perform the switching control in the switching control station independently of the change of the radio base station which interrupts information from a mobile machine. CONSTITUTION:A mobile communication system consists of a switching control station 1-1, radio base stations 1-21 to 1-2n, mobile machines 1-31 to 1-3m, a wired communication medium 1-4 capable of broadcasting, and an external link 1-5. The switching control station 1-1 switches information frames from or to mobile machines based on communication identifiers directly assigned to mobile machines or assigned to communication independently of radio base stations relaying the mobile machines. Thus, unnecessary processing is completely eliminated though relaying radio base stations are switched because of movement of mobile machines, and the delay for switching of radio base stations is prevented.

IPC: G11B7/09
Filed: 1993-02-26
Abstract: PURPOSE:To obtain an optical disk focus controlling apparatus which can execute stabilized focus control even when a defect is generated. CONSTITUTION:A defect detection circuit 30 detects a defect from an RF signal and outputs a high level signal DE during the period corresponding to the RF signal and a second defect detecting circuit 50 also detects a defect by detecting a level change point of a focus error signal (voltage V6) before correction to output the voltages V10, V15 of the predetermined pulse width for each level change point. Moreover, an analog switch 43 of a correction circuit 40 is changed with a signal SE as a logical sum of the signal DE and voltages V10, V15 and a voltage V6' obtained by lowering the level of the voltage V6 when a defect is detected is defined as a focus error signal FE. Thereby, satisfactory recording condition can be obtained even during recording of information to the additional recording type optical disk.

Inventor: SASAKI HIROYUKI
IPC: B01J19/00
Filed: 1983-03-11
Abstract: PURPOSE:To efficiently prepare a uniform ultra-fine particle by discharging the generated ultra-fine particle from a melting chamber within a short time, by obliquely arranging an electrode member, a gas inflow pipe and a gas outflow pipe so as to form a predetermined angle with respect to the stock material of the melting chamber. CONSTITUTION:An electrode member 3, a gas inflow pipe 1 and a gas outflow pipe 2 are obliquely arranged in an angle range of about 40-80 deg. with respect to the stock material A such as an alloy received in the recessed part 11a of the crucible 11 in a melting chamber 13. Predetermined gas (hydrogen-containing gas or nitrogen-containing gas) is flowed from nozzle pipes 6, 7 and an auxiliary nozzle pipe 8 to generate an arc between the leading end of an electrode element 5 and the upper surface of the stock material A. The stock material A is melted and the atmospheric gas is activated by said arc while an ultra-fine particle is generated from the molten stock material A by the reaction of the molten stock material A and the inert gas. The discharged gas containing the ultra-fine particle is rapidly exhausted from the gas outflow pipe 2 and is not stayed in the melting chamber 13.

Filed: 1986-02-27
Abstract: PURPOSE:To make it possible to economically form the support for a screen printing base plate wherein the size, shape and distribution of the perforated opening part are equal with each other, by forming a resin into a film in such a state that the liquid resin is present only in the recessed parts of a roll or an endless belt and releasing the resin film formed as an aggregate having a substantially closed shape. CONSTITUTION:An ultraviolet curable resin liquid 5 is applied to a roll 2 having recessed parts formed by etching a blank part so as to leave a pattern wherein substantially closed shapes are arranged independently in a closely contacted state. The adhered resin present other than the recessed parts is removed to allow the resin liquid 5 to be present only in the recessed parts and, in this state, the resin liquid is irradiated with ultraviolet rays from an ultraviolet irradiation apparatus 1 to be formed into a film. Thereafter, the resin film formed as an aggregate having a substantially closed shape is released from the roll 2. As a result, the support for a screen printing base plate wherein the size, shape and distribution of the perforated opening parts are equal with each other can be formed economically.

Title: System for supervising stuff multiplexing device
Inventor: MIYAMOTO HIDETO
IPC: H04J3/14
Filed: 1987-02-25
Abstract: PURPOSE:To reduce the scale of a supervisory circuit and to improve reliability by adding a bit of parity information to a stuff pulse in a multiplexing format and checking a parity bit. CONSTITUTION:Stuffing is executed by the 'misalignment' of a phase difference and a stuff pulse is inserted in accordance with a high-order group multiplexing format. The stuff pulse is used as a parity bit, the number of marks of the data bit until the stuff pulse is inserted is counted, and in the case of an even number, '1' is inserted as the parity bit or '0' is inserted. Respective low-order group signals count the number of marks in parity checking circuits 81, 82-8n, check an even parity or an odd parity and obtain the matching with the parity bit. Here, when a hard fault exists, the matching cannot be obtained and the can be discovered.

Title: Controlling method for rotary cooler
Inventor: KOIZUMI SAKAE
IPC: F27D15/02
Filed: 1980-03-29
Abstract: PURPOSE: To uniformly cool lumps to a prescribed set range by placing a telemeter at a position above the charge inlet of a rotary cooler and a thermometer at the discharge outlet and controlling the revolutional number of the cooler or an exhaust fan when the detected value deviates from a set range.  
     CONSTITUTION: The level of lumps charged into cooling vessel 11 is detected with telemeter 3, and the signal is sent to the 1st controller 5 and compared to a set value. When the level is lower than the set value, controller 5 instructs motor 6 for driving rotary drum 1 to rotate further slowly. When the level is higher than the set value, controller 5 instructs motor 6 to accelerate the rotation slightly. Thus, the stock in vessel 11 is kept at a level in the set range. The temp. of the lumps discharged after cooling is then detected with thermometer 7, and the signal is sent to the 2nd controller 8 and compared to a set value. When the detected temp. is higher than the set value, controller 8 instructs motor 9 of a blower attached to suction duct 2 to increase the volume of air sucked.
