Title: Control system for satellite communication demand assign multiple access
Inventor: TAKAMOTO HIROKI
IPC: H04B7/15
Filed: 1987-12-02
Abstract: PURPOSE:To transmit and receive a signal of other bit rate as well as a 64kbps signal by providing a variable bit rate modulator-demodulator to each earth station and using a multiple access controller to control the operating frequency band and the bit rate of an opposite modulator-demodulator based on the request from each earth station. CONSTITUTION:Plural earth stations 11-1n are provided respectively with a variable bit rate modulator-demodulator 4i. The earth station 1i among the earth stations 11-1n (n is a positive integer), for example, is connected to other earth station 11 via a satellite 2. A signal sent from a ground network is given from a signal input terminal 7i, demodulated by a modulator-demodulator 4i, frequency-converted and amplified by a transmitter-receiver 3i and outputted to the satellite 2 in a frequency fT'. The demand assign multiple access controller 5 instructs the operating frequency and the bit rate by providing the connection request of each earth station 1 to a relevant earth station 1i. A control signal from the said controller 5 is given to the modulator-demodulator 4i via a control signal input terminal 6i of the earth station 1i to set the operating frequency and the bit rate to a required value.

Title: Developing device
Inventor: TANAKA YOSHIHIKO
IPC: G03G15/08
Filed: 1990-11-07
Abstract: PURPOSE:To prevent an accumulation of a developer on a partition board and to form a normal image by maintaining the partition board at the upper position to allow to recirculate the developer when a developing roller is being driven, and rotating the partition board to the lower side when the roller is not driven, by a partition board rotating means. CONSTITUTION:When a developing roller 3 is driven and the copying is being carried out, a solenoid 11 is OFF and a partition board is pulled to the upper side by a spring 10 and abutted to a working plate 12. As a result, the developer in a housing 2 is cut off by the roller 3 and the excessive developer is dropped near a roller 8 passing through the upper side of the partition board 5. On the other hand, when the copying is not carried out, the solenoid 11 is ON, and the partition board 5 is rotated to the lower side making a shaft 5c as the axis. As a result, the developer remaining on the slope 5a of the partition board 5 is dropped near between the rollers 3 and 7. Consequently, even in the condition the developing roller 3 is not driven, the accumulation of the excessive developer on the partition board is prevented, and a normal image can be formed.

IPC: B66B13/14
Filed: 1987-12-01
Abstract: PURPOSE: To prevent a door butting or the reduction of an opening-closing speed by outputting a motor temperature signal by detecting a heating temperature of a motor of a door opening/closing device of an elevator, inputting this motor temperature signal to the speed command generating part or the torque limiter part, and controlling a speed or torque of the motor. CONSTITUTION: Torque of a motor 5 is controlled by a deviation signal of a command signal for commanding a speed of the motor 5 of a door opening/ closing device of an elevator and an actual speed of the motor 5. In that case, a motor temperature signal is outputted by detecting a heating temperature of the motor 5. A speed or torque of the motor 5 is controlled by changing the command signal or a torque limiter value of the motor 5 further by this motor temperature signal to thus obtain the door opening/closing device of an elevator prevented a door butting or the reduction of an opening/closing speed even if a resistance value of a coil changes, a carrying electric current changes and torque and a rotating speed of the motor change since the motor 5 is heated.

Title: Toner for electrostatic latent image development
Inventor: YASUNO MASAHIRO
IPC: G03G9/08
Filed: 1990-11-13
Abstract: PURPOSE:To make it have an excellent cleaning characteristic as well as to form it into such one that is excellent in fixability, chargeability and environmental stability by sticking and/or attaching an inorganic or organic grain, having specific mean grain size, tightly to a spherical toner grain surface. CONSTITUTION:An inorganic or organic grain, having a means grain size of 1/100-1/10 with the means grain size of a toner, is locally stuck and/or attached tightly to a spherical toner grain surface. Therefore proper irregularities are formed on the surface, so that even if the promotion of small grain size is planned to be done, good cleaning properties are securable, and in addition, a part being pressed onto a sensitizer surface by a cleaning blade is a surface of the spherical toner grain itself, whereby a possibility of contact by the grain is little in chance. With this constitution, improvement in the cleaning property is well promotable, and simultaneously control over such characteristics as largely depending on surface properties including chargeability, environmental stability, flowability, transferability, electric conductivity and so on becomes facilitated.

IPC: C21C7/00
Filed: 1998-10-27
Abstract: PROBLEM TO BE SOLVED: To provide a method for remarkably restraining the development of HIC and preventing the clogging of an immersion nozzle regardless of the level of casting speed in the continuous casting of steel having hydrogen induced cracking resistance. SOLUTION: In the continuous casting of the steel having the hydrogen induced cracking resistance, Ca in the molten steel is controlled to 10-50 ppm. In this way, non-metallic inclusion of Al2O3, etc., as precipitate in the steel is reacted with the Ca in the molten steel and removed as slag and the clogging of the immersion nozzle, etc., can be restrained. Further, the blowing of inert gas from the upper nozzle in a tundish, the fixed plate of a sliding gate and the immersion nozzle, etc., are unnecessitated. In this way, the mixture of bubble into the molten steel caused by the inert gas is prevented and the development of the HIC caused by the residual bubble in a cast slab is prevented.

IPC: B60L15/40
Filed: 1998-10-27
Abstract: PROBLEM TO BE SOLVED: To easily identify the present location of a train by detecting the present location of a train with an external physical quantity compared to route data on, and, if the detected present location deviates from the present location which is identified by a train location measuring part, correction is instructed to the train location measuring part. SOLUTION: An echo sounder transmitting signal, outputted from an echo sounder transmitting circuit part 21 of a roughness detecting part 2 is converted into ultrasonic wave by an echo sounder transducer 22 and is transmitted directly above a train car. The rebounded reflecting wave is received and amplified, converted into a digital signal by an A/D converter 24, and inputted into a control part 4. The control part 4 compares the information regarding roughness on the outside of the train car, which serves as the external physical quantity of the inputted digital signal, with the route data storing the location information measured by a train location measuring part 3 to detect the present location of a train.  If the detected present location deviates from the present location identified by the train location measuring part 3, a location correction command is outputted into the train location measuring part 3.
