Title: Translucent type spatial optical modulator
Inventor: OKOCHI NOZOMI
IPC: G02F1/135
Filed: 1990-03-31
Abstract: PURPOSE:To expand the range of application to the wavelength of light and materials by providing a displacing means which displaces an optical modulation part relatively to a photoconduction part in synchronism with the switching between write light and read light and arraying sensing parts and transparent parts alternately at the photoconduction part at intervals corresponding to the direction and quantity of the displacement. CONSTITUTION:A photoconductor layer 16 is laminated on the write light and read light incidence side of the optical modulating body layer 12 of the spatial modulator 10 across a buffer layer 14 and the photoconductor layer 16 consists of sensing parts 16A which form a charge image by the incidence of light and transparent parts 16B which transmit the incident light. Then when a vibrating body 28 is applied with a voltage from a power source 30, a photoconduction part 10A and an optical modulation part 10B are displaced relatively and the quantity of the displacement at this time is equalized to the intervals or pitches of the sensing parts 16A and transparent parts 16B. Consequently, the limitations of the wavelength of the light used to write and read information and materials used for the respective parts are relaxed and the application range is widened.

Title: Thyristor
Inventor: YUKIMOTO YOSHINORI
IPC: H01L29/10
Filed: 1979-07-09
Abstract: PURPOSE: To accelerate the control speed of the thyristor without lowering the withstand voltage thereof by lowering the shared voltage of a base layer formed with a gate electrode when forward voltage is applied thereto.  
     CONSTITUTION: p-Type gates 8 projected in a p-type base layer 3 are formed in the boundary between an n-type base 2 and the layer 3, and n + -type layers 9 are projected toward the intermediate of the gates 8 from the boundary between the base layer 2 and a p-type emitter 1 into the layer 2. Thus, when applying forward voltage thereto, voltage is shared only to the base layer 2 without sharing the voltage with the base layer 3 so as to largely reduce the layer 3 in thickness.Accordingly, the time from an n-type emitter 4 through the base 3 to the base 2 can be shortened so as to accelerate the arc without lowering the withstand voltage thereat. Further, a depletion layer extending from the gates 8 to the base 2 depletes the base 2, the n + -type layer reduces the carrier injection from the emitter so as to shorten the required time of cancelling the carrier. In this manner it can accelerate the arc extinguishing operation without lowering the withstand voltage of the thyristor.

Title: Utilizing method for soaking pit slag
Inventor: SHIMIZU SABUROU
IPC: C22B1/16
Filed: 1978-07-20
Abstract: PURPOSE: To utilize effectively the soaking pit slag, which has been abandoned as waste, as a MgO source or an Fe source, by charging the slag into a sintering machine or a shaft furnace.  
     CONSTITUTION: Soaking pit slag contg. about 30% by weight MgO is separated by a screen of a prescribed mesh, lumps being charged to a shaft furnace, and the powder to a sintering machine as MgO source and an Fe source respectively. Because the soaking pit slag contains 20% by weight Fe, and MgO not lower than about 30%, which is nearly equal to the MgO content of serpentine, the flowing property and desulfurizing capacity of the shaft furnace slag is improved with soaking pit slag similarly as with serpentine. The utilization of soaking pit slag reduces resource consumption and prevents environmental pollution caused by the abandonment of the slag.

IPC: B21B45/06
Filed: 1980-06-30
Abstract: PURPOSE: To provide the titled device which removes the scale on the surface of steel plates or accomplishes perfect descaling through formation of fine cracks in scale by disposing rough surface rolls in front of descaling headers which inject high pressure water.  
     CONSTITUTION: A steel material 1 which is transferred by table rolls 2 is touched to the surfaces of rough surface rolls 5, 5' in a screw down state, in the positions of said rolls. As a result, the scales on both surfaces of the material 1 are peeled from the surfaces of the steel material by the rough surfaces of the rolls, and further cracks are formed in the sheetlike scales by being pressed with the rough surfaces of the rolls, whereby they are made easy to strip from the surfaces of the strip materials. Hence, when the material 1 past between the rolls 5, 5' arrives at the position of high pressure descaling headers 3, the residual scales in the finely disintegrated and stripped state are thoroughly scattered and removed by the high pressure water injected therefrom. Here, dull rolls having roughened surfaces or the like are used for the rolls 5, 5'.

Title: Sampling frequency converter
IPC: H03H17/00
Filed: 1992-03-12
Abstract: PURPOSE:To improve the conversion precision when an input sample string is converted into an output sample string asynchronous with the input sample string. CONSTITUTION:An input sample string inputted from an input terminal 16 is subject to 8-multiple oversampling by a filter 18 and the result is sequentially written in an asynchronous RAM buffer 22. A sampling frequency comparison measurement means 30 counts a clock synchronously with the input sample string over plural word periods of the output sample string by a 22-bit counter 42 and counts the count as a highly precise sampling frequency ratio. A read control means 32 reads plural samples from the asynchronous RAM buffer 22 based on the measurement. An interpolation arithmetic operation section 34 uses plural read samples to apply interpolation processing and generates the output sample string and it is outputted. When a sampling frequency ratio is fluctuated, the measurement period is reduced to improve the tracking performance. Furthermore, the read control means 32 implements correction processing of the read address to prevent overrun of the write address.
