Patent JP-H0276429-A (JP)
Title: Clock reproducing circuit
Inventor: NAGASU MASAHIRO
IPC: H04L7/033
Filed: 1988-09-13
Abstract: PURPOSE:To reproduce a stable timing clock by dividing the frequency of a clock signal by a counter to obtain a primary reproducing clock signal having an edge in each data cell of a digital data signal. CONSTITUTION:Exclusive OR operation between a digital data signal (n) led into a terminal IN and a digital data signal O delayed by an optional time through a delay circuit 13 is executed by an exclusive OR circuit 14 and an edge detecting pulse signal P is outputted. The counter 16 repeats reset operation every arrival of the signal P to divide the frequency of a clock signal Q outputted from a clock generator 15 and outputs a primary reproduced clock signal R having an edge in each boundary between the data bit cells of the signal (n). When the signal P is supplied to the succeeding digital phase locked loop(DPLL) circuit 17 as an input signal, a stable timing clock signal synchronizing with the phase of the signal (n) can be reproduced.

Title: Linear drive device
Inventor: ITAGAKI AKIYOSHI
IPC: B25J9/02
Filed: 1989-09-05
Abstract: PURPOSE:To operate the subject linear drive device at a high speed without making high noise and improve the positioning accuracy by forming a flat belt, for converting the rotation of a drive pulley into the linear motion of a slider made of elastic material of large elastic coefficient. CONSTITUTION:When a motor P is started, the rotation is reduced by a speed reducer 10 is transmitted to a drive pulley 6, and a slider 12 is linearly moved by the motion of a flat belt along with the rotation of the drive pulley 6. The speed and stop position of the slider 12 are controlled by regulating the rotation speed and rotation angle of the motor 9 based on the singles from a detector 11 by means of a controller. At this time, even if the slider 12 is accelerated at high speed to be moved at high speed and reduced at high reducing speed to be stopped, the flat belt 13 is not stretched and moreover not agingly lengthened by making the flat belt 13 of steel whose elastic coefficient is large, and therefore, which is not largely lengthened even if large tension is applied thereto. This leads to high speed operation without high noise and improves the positioning accuracy.

Title: Method and apparatus for turning salt water into fresh water by electrodialysis
Inventor: KURODA OSAMU
IPC: C02F1/469
Filed: 1987-09-16
Abstract: PURPOSE:To make it possible to directly utilize fluctuating power supply with almost no electricity storage, by suitably selecting the proportions of electrodialysis tanks for respective desalting operations at respective salt concentration levels, in a process in which original water is step-wise desalted so as to have a medium salt concentration and then to have a low salt concentration through step-wise performed batch operations employing a plurality of electrodialysis tanks. CONSTITUTION:Original water from an original water tank 9 is desalted in a plurality of electrodialysis tanks 8, while salt water is being circulated through a circulating tank 10. In this electrodialysis apparatus for turning salt water into fresh water, either of two operations can be selected: a high concentration operation in which the original water is desalted to the extent that it has a salt concentration intermediate between the salt concentration of the original water and that of fresh water, and fed to a storage tank 11 for intermediate-concentration water; and a low concentration operation in which the intermediate- concentration water is desalted and turned into fresh water, and fed to a fresh water storage tank 12. In the case where there is a large amount of electric power supply to the apparatus for turning salt water into fresh water, the proportion of electrodialysis tanks for high concentration operation is heightened. On the other hand, in the case where the amount of electric power available is small due to the fluctuations in the amount of electric power generated or the increase in the electric power consumption by other equipments, the proportion of electrodialysis tanks for low concentration operation is heightened. Thus, the amount of electric power consumed by the whole apparatus for turning salt water into fresh water is controlled with time to proper values.

Title: Solid-state image pickup element camera
Inventor: TAKEMURA HIROO
IPC: H04N5/351
Filed: 1987-09-14
Abstract: PURPOSE:To improve vertical resolution by giving memories a storage capacity for two fields and alternately reading picture signals in first and second field memory parts in terms of lines or in terms of respective memories. CONSTITUTION:A high speed transfer pulse and a write gate control pulse alternately divide and transfer the charges of a high speed transfer part 2, the charges of a high speed transfer string 21, for example, between two memory parts 31a and 31b at every line. Consequently, the charges corresponding to two fields (odd field and even field) are stored in the high speed transfer string 21 and the memory parts 31a and 31b. For division, a gate part 51 for division is generated between the high speed transfer string 21 and the memory strings 31a and 31b, and it is controlled by the write gate control pulse from a timing pulse generation circuit 12. Consequently, the picture signals are read for every field through a gate part 61 and a horizontal transfer part 4. Thus, vertical resolution can be improved and flicker due to the time difference of inter-field is prevented from occuring.
