Abstract: PURPOSE:To eliminate necessity for allocating the data bit of a main signal and to prevent transmission efficiency from being lowered by executing the transmission/reception process of a public exchange telephone network by transferring the data bit of the main signal and an S bit in the device to execute digital signal transmission by forming an envelop. CONSTITUTION:A transmission/reception process executing means is provided to transmit/receive a data multiplying the envelop through a digital line 50 to a data terminal equipment 32, which is connected through a public exchange telephone line network 40 to this digital line 50, and a DTE side interface part 21 of a time division multiplexer and a DEC side interface part 22 of the time division multiplexer are provided. The transmission/reception process executing means is equipped with a MODEM control signal generating means to generate a MODEM control signal from plural signals generated by combining the state of the data bit of the main signal and the state of a status bit applied to the envelop. An interface process is executed in a general exchange telephone network to handle the plural MODEM control signals only according to the states of the main signal and of the S bit. Thus, digital signal transmission can be efficiently executed.

Inventor: KATSUTA MAKOTO
IPC: G03F1/00
Filed: 1980-12-19
Abstract: PURPOSE:To print the same mask on the both front and rear surfaces, by branching the projected light sent from the photomask into two directions and by projecting the branched light to the front and rear surfaces of the printing material, which is the shielded photoresist, with the use of plural sheets of reflecting mirrors.

Light passed through the mask 14 passes through a projection lens 15 and is divided into two directions by a semi-transparent mirror 16. A reflected light is reflected by reflecting mirrors 18 and 19 and forms an image 23 of the mask 14 on a side of a printing material 22. Light passed through the other semi-transparent mirror 16 is reflected by a pentagonal prism 17 and reflecting mirrors 20 and 21 and forms an image 24 of the mask on the other surface of the printing material 22. Then, the image of the mask 14 is simultaneously printed on the both surfaces of the printing material.

Abstract: PURPOSE:To obtain result of monitoring in a short time without requiring a highly advanced equipment by measuring luminescence which is generated by casting an excitation light to specimen containing quinolene agent under acid conditions. CONSTITUTION:Keep 2-3 spherical absorbent waddings with a diameter which is approximately 5mm in a mouth, place the absorbent waddings (a) which fully contain saliva on a gauze (b) of a transparent sample tube (c), and then hold the gauze b, cover it with a lid, and then centrifuge it approximately for one minute, thus enabling a oral quinolene agent offxacine(OFLX) to be collected quantitatively.

Title: Wiggler magnet
Inventor: KOBAYASHI AKIRA
IPC: H05H13/04
Filed: 1991-07-19
Abstract: PURPOSE:To provide a converging wiggler magnet having trapizoidal magnetic poles capable of equalizing resonant conditions irrespective of incident positions of electronic beam as well as of improving evenness of intensity of peak magnetic field in the X-direction. CONSTITUTION:In this wiggler magnet C the taper angles of trapezoidal magnetic poles 1 are juxtaposed in the Z-axis direction through intermediate magnets 2 formed in parallelogram in plan view so that they may be made wide alternately in the positive and negative directions of the X-axis. Magnetic pole columns 3, 3' are formed by the poles 1 and the magnets 2 and arranged in the Z- direction in a face-to-face manner to generate alternate magnetic fields. In this case, the magnetic pole 1 has the magnetic field to make passing electron beam run in a meandering manner in the direction where the trapezoidal shape becomes wide in its width. The distance between the opposite magnetic pole faces of the magnetic poles 1, 17 becomes short in proportion to the narrowing degree of taper angle of the trapezoidal shape. With such a construction, it is possible to realize the same peak magnetic field in any position in the X- direction, whereby the same resonant condition can be achieved even if the incident positions and angles of electrons are different.

IPC: G11C11/56
Filed: 1985-08-16
Abstract: PURPOSE:To suppress the noise generating quantity and to execute a writing accumulation with high accuracy by making a writing voltage at the time of the change of the data line voltage different from a writing voltage accumulated to the memory thereafter, avoiding the noise and making different the driving waveform of the data line at the time of the writing between data line pairs. CONSTITUTION:An address signal a0 is 'H', a data line 20 is selected and a pulse phiX is changed over to a line 48. By the output of an X decoder 35, an element 52 is conducted, the line 48 is connected to a word line 7 and the un-designated word line is pulled down to VSS. A voltage phiDD before writing is applied, a data line D20 only is VSS through an element 57, reading pulses phiW0 and phiC1 of a temporary memory circuit 34 are alternately applied, the writing gate is driven by phiW2, the voltage of D20 is boosted and through an auxiliary data 45, D21 is pulled out to VSS. Since the data line pairs simultaneously cause the change of the voltage contrastively, the changes of the voltage of the word line and others are small and the noise is little at the time of the writing. Further, when the data line is changed, a word line voltage V1 is kept lower than the writing voltage V2 of the cell, and then, the memory is not influenced by the noise. By such a constitution, the signal voltage is controlled by the word line voltage with the good accuracy and the low noise can be written.
