Title: Transmission control system for mobile radio communication system
Inventor: ABE HIROHITO
IPC: H04B7/26
Filed: 1989-04-17
Abstract: PURPOSE:To reduce the transmission error and to improve the transmission efficiency by selecting transmission speed corresponding to the line quality detected among plural kinds of the transmission speeds prepared in advance, and setting this speed to a communication channel. CONSTITUTION:A transmission speed setting control means 23a inputs a detection value of an error rate of a notice signal from an error rate detection section 24 at calling, and selects a transmission speed proper to the quality of a radio line from a data table at a present point of time from the detected value. Then the transmission speed is informed to a command station or a mobile station being a communication opposite party via a communication channel, set to a modulation section(MOD) 21 of its own station and the transmission speed is set to a demodulation section(DEM) 22 in response to the transmission speed informed from the command station or the mobile station at the caller side at the arrival of a call. Thus, the optimum transmission speed is set in response to the quality of the radio line at each occasion at the start of data transmission. Thus, the data transmission with less error data phase or excellent efficiency is attained.

Abstract: PURPOSE:To obtain an inexpensive binder for sintering substitutable for expensive quick lime or quick-setting cement by treating a powdery mixture of ferromanganese slag and/or silicomanganese slag with steel making slag cooled rapidly from a molten state, water granulated blast furnace slag and an exciting agent. CONSTITUTION:This binder for sintering is obtd. by treating a powdery mixture of ferromanganese slag and/or silicomanganese slag with steel making slag cooled rapidly from a molten state, water grandulated blast furnace slag and one or more kinds of substances selected among CaSO4.2H2O, CaO, Ca(OH)2, CaCl2, NaOH and Na2CO3 as an exciting agent. All of the slags are inexpensive and the exciting agent is used by a small amount. The effect of the binder on a sintered product is comparable to that of conventional expensive quick lime. Blast furnace slag and steel making slag as by-products from the steel industry are recycled and ferromanganese slag and silicomanganese slag as by-products from a ferroalloy maker are utilized, so the binder is profitable.

Title: Electromagnetic propulsion device
Inventor: TERASHITA AKIHIRO
IPC: H02N11/00
Filed: 1988-04-19
Abstract: PURPOSE:To simplify the structure of device by generating driving force through a mutual action of AC magnetic field and electromagnets by the use of a plurality of electromagnets. CONSTITUTION:Air-core electromagnets A and B in the same direction are fixed to a supporting pedestal 1 at a distance (d) apart. Alternate current of the frequency F=C/4d (where C is a light velocity) is caused to flow from a power source 2. At this moment, the difference delta=delta1-delta2 between the current phase difference (delta1) flowing to the electromagnet A and the current phase difference (delta2) flowing to the electromagnet B is adjusted using a phase shifter 3. So as not to give electromagnetic influence to outside, the supporting pedestal 1 is enclosed with electromagnetic wave shielding material 4. By adjusting the power of the AC power source in this way, the strength of force can be controlled, while by adjusting the difference of phase differences, the direction of force generated can be adjusted.

Abstract: PURPOSE:To control exposure quickly by providing an automatic exposure control mechanism which provides prescribed surface potential with respect to a prescribed density. CONSTITUTION:Potential is detected by a sensor 7 between a full surface exposure lamp 4 and a developing electrode 5, and the output of a high voltage transformer 9 is regulated.

The reflected light of that time is conducted onto a photoreceptor 1 via mirrors 12, 13 thereby exposing the photoreceptor. The standard white potential on the photoreceptor is detected with the sensor 7 and when the potential attains a target value, a signal for stopping the change of the quantity of light is emitted to the lighting control circuit 14 of the lamp 11 from a control circuit 8. The circuit 14 stores the exposure of the stopping time, and when a copy signal goes on,the lamp 11 is lighted at that stored exposure.
