Title: Recovery apparatus for edta
Inventor: YOSHIDA TADASHI
IPC: C07C67/00
Filed: 1987-05-29
Abstract: PURPOSE:To provide an apparatus for the continuous recovery of ethylenediaminetetraacetic acid (EDTA) as high-purity crystal in high efficiency, by filling free acid of EDTA in a crystallization tank as seed crystal and forming a specific discharging port at the outer circumference of a stock liquid nozzle attached to the bottom of the crystallization tank. CONSTITUTION:Free acid (H4Y) of EDTA is filled in a crystallization tank 5 as a seed crystal. An EDTA-containing liquid and a circulation liquid having a pH of <=3 are introduced into the tank from its bottom and the crystal is fluidized by ascending flow of the liquids to effect the growth of H4Y crystal 6 to a prescribed particle diameter. The grown crystal 6 is extracted from the tank bottom provided with one or more discharging ports 4 of the circulation liquid (circulation liquid nozzle) around the outer circumference of a stock liquid nozzle 2 attached to the bottom of the crystallization tank. An ascending flow of the circulation liquid is formed parallel to the direction of the stock liquid flowing out through the stock liquid nozzle and the direction of crystal flow. The local increase in the supersaturation at the bottom of the crystallization tank and the turbulence of the flow of supersaturated solution are prevented and the amount of residual nuclei can be decreased by the use of the present EDTA-recovery apparatus. The EDTA-recovery apparatus improves the efficiency of the following washing and dehydration processes and simplifies the operation of the processes.

Title: Method of automatically operate trains
Inventor: MORIHARA KENJI
IPC: B60L15/20
Filed: 1977-11-02
Abstract: PURPOSE: To provide a operation method with an improved property of following up the target speed by expanding the range of acceleration or deceleration in a set zone depending on conditions such as position of a step, command speed and running resistance in a step control with a proper step-maintaining zone set.  
     CONSTITUTION: To follow up the target speed, the actual state of the vehicle is detected. According to the condition thus detected, a step is changed to cause a contraction so that the intended step maintaining zone A (b≤y≤a, e≤x≤f) is retained. In an automatic train operation methods employing a control pattern with a gain achieving this, a zone A 1  (a≤y≤c, o≤x≤f) and a zone A 2  (d≤y≤b, e≤x≤ o) are added to the zone A to form a step maintaining zone and the range of the acceleration or deceleration range in the step maintaining zone is expanded in proportion to a deviation in acceleration or deceleration given to vehicle when the condition thereof is changed by one step. Symboles c and d indicates an allowable deviation of speed with respect to the target speed.

Filed: 1989-05-25
Abstract: PURPOSE:To prevent a diagnostic device from coming into a high load state by initializing a processor so as to incorporate at again into a system when fault part information stored in a storage means does not coincide with fault part information which is actually detected. CONSTITUTION:A fault cause in the processor 1, which is read by an error display FF read circuit 21, is stored in a fault history register 22 and is compared in a comparator 23 with a fault cause which is previously stored in the fault history register 22. When non-coincidence is detected in the comparator 23, that a fault detected this time differs from the fault cause stored in the fault history register 22 is shown. Thus, the fault is judged to be intermittent one, and the reset of the processor 1 is instructed to a reset circuit 24. When coincidence is detected in the comparator 23, the fault is judged to be fixed one and the processor 1 is not reset.

Abstract: PURPOSE:To make it possible to obtain a plurality of types of semiconductor devices using one metal mold for molding by a method wherein groove parts of a constant width are provided in the same directions as those of the arrays of outer leads and at positions to correspond to the point parts of the outer leads. CONSTITUTION:A semiconductor element 6 is mounted on a lead frame, is resin-sealed and thereafter, outer leads 8 of the lead frame are bent in a J form. Moreover, a resin-sealing part 13 to correspond to point parts 12 of the outer leads 8 is provided with groove parts 14 of a constant width in the same directions as those of the arrays of the outer leads 8.

Title: Map display device
Inventor: MITSUDA AKIRA
IPC: G08G1/0969
Filed: 1994-06-15
Abstract: PURPOSE:To subject characters and symbols form vertical to horizontal conversion or horizontal to vertical conversion according to a correct designation method even if a map is rotated 90 deg.. CONSTITUTION:While the background data depicted in a buffer memory 6 is rotated 90 deg. and developed around the display center of a display 9, character and symbol data is rotated 90 deg. as well and is simultaneously subjected to format conversion so as to coincide with the normal designation. The device is so formed that the 'en' characters or 'en' symbols to be converted to vertical writing are compressed to a 1/2 double em in a vertical direction and, therefore, the vertical writing character symbol strings and horizontal writing character symbol strings are confined within the nearly the same designation area before and after 90 deg. rotation of the map. Such trouble that the character and symbol strings are overlapped on the background data, such as roads and main structures by the 90 deg. rotation and that the maps are hardly readable is prevented.

Title: Search system for fault repeater
Inventor: MOCHIDA ARIHIRO
IPC: H04B17/40
Filed: 1978-10-30
Abstract: PURPOSE:To make it possible to discriminate immediately a fault repeater at a terminal station by providing a PCM transmission system with a circuit which sends fault information of a pattern characteristic to a repeater, and then by sending the fault information synchronizing with a clock signal of a phase synchronous oscillator on fault occurrence. CONSTITUTION:On detecting (c) an abnormal decrease in level of a PCM signal applied to input terminal IN due to a fault occurring to a prior-stage repeater or transmission line, detection circuit DET opens gate G3 while closing gate G1. An abnormal output from timing extraction circuit TM cause input break detection circuit OFD to cut off a timing signal inputted to phase synchronous oscillator PLO, making PLO self-oscillate. Clock signal (a) outputted by PLO in this state is divided (b) by divider DV1. At this time, output signal (d), consisting of an all-mark signal and all-space signal repeating at period T, is sent OUT synchronizing with the clock signal. A terminal station provides the immediate discrimination of the fault repeater by detecting period T.

Abstract: PURPOSE: To provide the device which is capable of adjusting focus with low voltage without vibrations by mounting the objective lens of the microscope to bimorph type piezoelectric elements and providing a means of detecting the focus position and driving the element and a detecting means for lens movement amount.  
     CONSTITUTION: The slide glass specimen 1 of the microscope is magnified by an objective lens 2 and is photo split by a beam splitter 6. The split beams form the image on the photo detecting plane of a one-dimensional image sensor 7. The optical density image is converted to an electric signal which is then converted to a focus position detecting signal in an analog signal processing part 8. The focus position is detected in an automatic focus adjustment control part 10. Driving of the objective lens part is accomplished by applying voltage to the bimorph construction comprising affixing together two sheets of piezoelectric elements 3, 4. Although the amount of deflection varies with the applied voltage, the material of an elastic plate 5 and others, the size adjustment of about 10μ may be readily performed through voltage application of ±100V.
