Title: Fine flock removing apparatus in circular precipitation basin
Inventor: FURUYA YUUICHI
IPC: B01D21/02
Filed: 1983-02-16
Abstract: PURPOSE:To prevent the effluence of fine flocks flowed out along with flooded water by dropping the same by a precipitation plate, by providing a precipitation promoting chamber having an oblique precipitation plate arranged therein along the outer periphery of a precipitation basin while allowing the flooded water from the precipitation basin to pass through said precipitation chamber. CONSTITUTION:Raw water to be treated in a precipitation basin 1 is flowed into the precipitation basin 1 from a raw water supply pipe 11 and flocks in the raw water is accumulated on the bottom surface 4 of said basin while precipitated under its own wt. Subsequently, they enter a pit 8 by the action of a scraper plate 5 revolved on the bottom surface 4 and discharged to the outside by a sludge withdrawing pipe 9 while fine flocks are whirled up by the movement of the scraper plate 5. These fine flocks enter a precipitation promoting chamber 15 prior to reaching an outflow line 13 and accumulated on each oblique precipitation plate 16 by the action of said oblique plate 16 and, when the accumulated flocks reach a predetermined amount, they are precipitated on the bottom surface 4 of the precipitation basin 1. Supernatant water is flowed out to the outflow line 13 from a flooding weir 12 and taken out to the outside by an outflow pipe 25.

IPC: C08J5/22
Filed: 1983-02-16
Abstract: A method of installing an ion-exchange membrane in an electrolytic cell in which the membrane is expanded by stretching to increase the surface area per unit weight of the membrane and the expanded, stretched membrane is secured to the electrolytic cell or to a part thereof. The stretching is preferably effected at elevated temperature and the expansion produced by stretching may be <<locked>> into the membrane by cooling the expanded, stretched membrane to a lower temperature prior to installation of the membrane in the electrolytic cell.

Title: Hot water supplier
Inventor: FUJINO HIROSHI
IPC: F24H1/14
Filed: 1987-02-02
Abstract: PURPOSE:To obtain a hot water supplier at which condensed water does not generate even in case when the operation of supplying low temp. warm water is carried out by a method wherein a primary hot water outlet pipe is connected to a hot water supply pipe line for supply of high temp. hot water and a secondary warm water outlet pipe is connected to the hot water supply pipe line for supply of low temp. warm water. CONSTITUTION:Before high temp. hot water is supplied, the water flowing from a water inlet pipe 3 into a heat exchanging pipe 2 flows to a primary hot water outlet pipe 11 through the whole course of the pipe 2 and then is sent out to a hot water supply pipe line 18 through a primary inlet passage 23, a valve chamber 22, and an outlet passage 25. In this case, the water flowing from the pipe 3 is heat-exchanged and heated enough in the whole course of the pipe 2. Before low temp. warm water is supplied, the water flowing from the pipe 3 into the pipe 2 is discharged from the middle of the pipe 2 to a secondary warm water outlet pipe 12; heat exchanger effectiveness is therefore reduced properly and, as a result, though the burning of a burner 13 is carried out in such a burn-up condition as to generate no condensed water, desired low temp. warm water can be supplied.

Such pulse signal group is batch processed in the multichannel analyzer 9, and is displayed in a display device 10. Therefore, the number of signal cables and measurement processing parts may be reduced, so that the intended purpose may be attained.

Title: Process selecting system
Inventor: NAKAYAMA TAKESHI
IPC: G06F9/42
Filed: 1985-02-07
Abstract: PURPOSE:To perform processing selection with a small number of steps by using a subroutine selected among plural ones as bit information and producing the jump/reset addresses from the time series output of information on the subroutine selection bit and a table. CONSTITUTION:A shift register 1 stores a bit corresponding to the selected processing subroutine in the form of '1'. When a jump instruction JSX is execut ed at an address 1,000, an address 1,002 of a processing subroutine 1 following the JSX is stored in a pointer register 6. The high-order four bits of a counter 3 are all set at '1' owing to the generation of the JSX. Then the register 1 is shifted left by two bits and stopped when a carry bit 2 is set at '1'. Then only the high-order four bits of the counter 3 are counted up and supplied to an adder 7 to be added with the value of the pointer 6. As a result, the head address of a subroutine 2 of an address 1,004 is supplied to a program counter 9. Thus the subroutine 2 is processed.

Title: Magneto-optical disk device and magneto-optical recording medium and optical head
Inventor: SHIMANO TAKESHI
IPC: G11B11/10
Filed: 1995-02-13
Abstract: PURPOSE: To widen the permissible width of the groove depth to cancel the crosstalks of the signals from adjacent tracks of a magneto-optical disk which narrows a track pitch by recording signals in both of guide grooves and inter-groove spacings. CONSTITUTION: The light spot 1 on the surface of the magneto-optical disk 2 is arranged at the boundary of the guide groove 4 and the inter-groove spacing. The groove depth is made to nearly λ/8. Further, a phase difference of nearly λ/8 is applied together with the phase difference by a substrate retardation and Kerr ellipticity between the incident linearly polarized light direction component and the linearly polarized light direction component orthogonal therewith of a reproducing optical system. The codes of the phase differences are inverted at the time of guide groove reproducing and at the time of inter-groove spacing reproducing. The simultaneous reproduction of the guide grooves and the inter-groove spacings is made possible if such reproduction is executed by separating the optical system to two systems.  As a result, the permissible width of the groove depth is expanded and the productivity of the magneto-optical recording media is improved. Since the simultaneous reproduction of the guide grooves and the inter-groove spacings is possible, the transfer speed of information is improved.

Also, when the exposure of 2nd shot and thereafter are performed. After marks 1b-1d are set on the apparatus main part and aligned as in the 1st shot, the exposures are carried out. The masks 1a-1d with four different patterns are successively transferred to the direction of arrows (l) and the substrate 3, which is an object to be exposed, is shifted by an X-Y stepping stage 4 so as to make four divided sections to be exposed successively. After the alignment is finished, the masks 1a-1d and the substrate 3 are scanned by a fixed mirror projection system 5 as one body and the patterns on the masks are transcripted onto the substrate 3.

Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To prevent the error of rearrangement by providing a collection section with a fill-up detecting means for detecting that the collection section is filled up and a remaining detecting means which detects that articles remain in the collection section, thereby taking out the whole of letters in a collecting means. SOLUTION: When the fill-up detecting means 107 detects the fill-up of the collection section, fill-up processing is started. When an operator takes out the letters 1 of the collection section, the fill-up detecting means 107 does not detect the fill-up any more. When the remaining detecting means 110 detects the letters 1, the fill-up processing is continued on decision that the letters 1 still remain in the collection section. When the remaining detecting means 110 detects the absence of the letters 1 in the collection section, the fill-up processing is stopped and the feeding of the letters 1 to the collection section is started. The letters 1 are surely taken out by using the remaining detecting means 110 to establish the stop conditions of the fill-up processing in such a manner and the rearrangement in erroneous order may be prevented.
