Title: Production of cis-epoxysuccinic ester
Inventor: YOSHITANI KIYOHIKO
IPC: C07D303/48
Filed: 1978-12-22
Abstract: PURPOSE: The esterification is effected by reaction of a cis-epoxysuccinate salt and an alcohol in the presence of sulfuric acid, thus producing title compound used as a raw material for detergent builder, crosslinking high polymers, polyamides, etc., in high yield with no formation of by-products.  
     CONSTITUTION: The acid or normal salt of cis-epoxysuccinic acid, e.g., disodium cis-epoxysuccinate or sodium hydrogen cis-epoxysuccinate is made to react with a lower alcohol as methanol in the presence of sulfuric acid under conventional conditions, thus producing said cis-epoxysuccinic ester in almost 100% yield with no formation of by-products. Usually, the cis-epoxysuccuinic acid is separated from the reaction mixture in the form of the above salt in the practical production and the direct use of the salt for the esterification can omit one process for the formation of the free acid, resulting in the advantage on facility and economics.

Title: Phase shifter
Inventor: YAMAGIWA KAZUO
IPC: H03H11/20
Filed: 1978-12-18
Abstract: PURPOSE:To prevent the level variation and distortion due to temperature and frequency, by picking up the two input signal of opposite polarity after phase-shifting for a given amount respectively at two phase shift circuits. CONSTITUTION:When the input signals e and e- of opposite phase are fed to two phase shift circuits from the input signal sources E and -E, the signalse2 and e3  mutually in opposite phase delayed by theta to the signal e and -e from the junctions f and g can be obtained. The phase shift theta is controlled with the DC control voltage Ec fed to the DC control constant current sources 1 and 2. The signals e2,e3 are fed to the transistors Q10,Q11 of the differential amplifier 3 and are in differential amplification, and the difference between the signals e2 and e3, i.e. the signal e4 in phase with the signal e2 and delayed for the phase by theta is obtained from the terminal t5. Thus, even if distortion or level variation is caused to the signals e2,e3,  it can be cancelled each other in the differential amplifier 3 to obtain the signal e4  almost without distortion and level variation.

Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To provide an onboard navigation apparatus which prevents a driver from overlooking pedestrians by informing the driver of the presence and a rough position of pedestrians at intersections without greatly changing an existing system. SOLUTION: The onboard navigation apparatus has an intersection enlarged view display function whereby an enlarged view of an intersection showing a magnified shape of the intersection is displayed to a display when it is detected that one's vehicle approaches the intersection. The apparatus divides the enlarged view displayed to the display to four partial areas 24a-24d, specifies partial areas among the partial areas 24a-24d where pedestrians are actually present, and further overlaps pedestrian marks 26 with predetermined position of the specified partial areas where the pedestrians are present on the enlarged view displayed to the display. Therefore, a sufficient effect of preventing pedestrians from being overlooked can be obtained by a minimum addition of processes.

Abstract: PURPOSE:To send a signal subjected to frame alignment without a delay after establishment of synchronization by applying a phase difference signal to a selector directly as a select signal by a select signal updating means when a synchronizing detection signal is applied to the updating means. CONSTITUTION:A multiplex synchronization means 1 applies synchronization detection to a multiplex signal resulting from multiplexing n-series of signals of m-bit structure including a synchronizing signal in one frame structure for each series and sends a synchronizing detection signal to a phase difference detection means 21 when the synchronization is taken. The phase difference detection means 21 detects a difference between the timing when the synchronizing detection signal is inputted and the timing of a reference phase by a reference counter 22 to send a relevant phase difference signal. A memory 3 has n-set of memory areas, in which the signal is stored at each input, and m-phase signals whose phases are sequentially shifted are outputted and a selector 41 selects a signal with a phase corresponding to the inputted select signal among m-phase signals outputted from the memory 3. A select signal updating means 61 selects a phase difference as a select signal when the synchronizing detection signal is inputted and sends it directly to the selector 41.
