Title: Socket connector attaching construction
Inventor: AOKI TSUTOMU
IPC: H01R13/73
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To make it possible to avoid the danger of breaking an optical fiber cable by inclining a socket connector arranged on a substrate to a predetermined angle in a direction where the optical fiber cable is led in and by fixing with a freely movable screw in a long hole. SOLUTION: A substrate 1 is built in an electronic equipment, and an arc- shaped long hole 5 has a desired radius of gyration at a predetermined position at a symmetrical position of a concentric circle. A socket connector 2 located on the substrate 1 is inclined by a predetermined angle in a direction at the right lower side where an optical fiber cable 6 is connected through an optical fiber cable connector 4 and is fixed with a screw 3 which is freely movable inside a long hole 5. Thus, the optical fiber cable 6 can be so connected with a curve that no excessive force is applied and thus the danger of breaking the optical fiber cable 6 can be avoided.

Title: Membrane separation apparatus
IPC: C02F1/44
Filed: 1992-03-24
Abstract: PURPOSE:To provide treated water with excellent water quality stably and efficiently for a long period without enlarging the installation, increasing the installation space, and soaring the water manufacturing cost by installing a first-stage reverse osmosis membrane separation apparatus having a spacer and a second and a third reverse osmosis membrane separation apparatuses to which water passed through the first apparatus is led successively. CONSTITUTION:A membrane separation apparatus is provided with a first stage pretreatment RO membrane separation apparatus 6 having a corrugated board spacer, a second stage first RO membrane separation apparatus 4 to which water passed through the former apparatus is led, and a third stage second RO membrane separation apparatus 5 to which water passed through the second stage apparatus is led. Consequently, since the pretreatment RO membrane separation apparatus 6 having a corrugated board spacer is installed in the pre-stage of two-stage RO membrane separation apparatuses 4, 5, it is unnecessary to install a clarifier such as a filration apparatus, etc., in their pre-stage and Ca ion and A ion are efficiently removed. Without lowering the fluxes of the first RO membrane separation apparatus 4, carbonic acid removing efficiency is heightened by adding NaOH to the permeating water and carrying out two stage RO treatment.

IPC: C04B35/584
Filed: 1993-03-25
Abstract: PURPOSE:To obtain a guide member without damaging a surface of a cap by forming a part sliding with a metallic can of a composit ceramic containing a free carbon. CONSTITUTION:An aluminium can for two pieces without an upper cap which is produced in a punching process I is guided with a guide member 1 in order to convey it to a next printing process II. In an upper guide 2 and a lower guide 3, each sliding part 4 is joined on a part to be brought in contact with a can A, and each attaching hole 5 in order to assemble it to a conveying device is provided. The guide member 1 is used of a composite ceramic containing a free carbon as the sliding part 4. The composite ceramics is composed of a ceramic body of alumina, etc., and the free carbon at least on a front surface part. For example, it is obtained by mixing carbon powder in a raw material of ceramic and firing. Therefore even if a metallic can with comparatively low hardness is used, the guide member without damaging the front surface of the can is obtained.

Title: Field information detecting circuit in ntsc signal
Inventor: KUMASAKA YUTAKA
IPC: H04N5/93
Filed: 1988-03-19
Abstract: PURPOSE:To surely detect odd field information and even field information in an NTSC signal with simple circuit structure by inputting a horizontal synchronizing signal and an equalizing pulse from a synchronization separating circuit to the set terminal and the reset terminal of an SR latch circuit and receiving a vertical synchronizing signal by a clock terminal. CONSTITUTION:A synchronization separating circuit 1 separates a horizontal synchronizing signal HS, a vertical synchronizing signal VS and an equalizing pulse EP from the NTSC signal, and an SR latch circuit 2 receives the horizontal synchronizing signal HS and the equalizing pulse EP respectively by its set terminal S and reset terminal R. A D latch circuit 4 receives a delayed vertical synchronizing signal VS' from the synchronization separating circuit 1 by its clock terminal CK and thus, latches an output from the SR latch circuit 2 in the fall timing of the vertical synchronizing signal VS'. Thus, in the case of an odd field, when the SR latch circuit 2 is set by the horizontal synchronizing signal HS, the output of the D latch circuit 4 becomes H, and in the case of an even field, it becomes L.

Abstract: PURPOSE:To suppress the increase of a chip size to the minimum and to execute the failure relief and rewriting of ROM data by providing a spare memory cell whose structure is different and in which the ROM data can be written. CONSTITUTION:As a spare memory cell 20 for relieving a failure generated in body memory cells 11, 12 and replacing partial ROM data, the spare memory cell 20 whose structure is different from that of these body memory cells 11, 12, which does not use a bit line and a word line of the body memory cells 11, 12 in common, and also, in which ROM data can be written is provided. For instance, the body memory cells 11, 12 are formed by the smallest pattern that can be obtained on the process, and the spare memory cell 20 is formed by a comparatively large pattern. In this case, when the body memory cells 11, 12 and the spare memory cell 20 use the bit line or the word line in common, it is difficult to form the pattern, but since they are not used in common and the spare memory cell 20 is provided on the area being different from the body memory cells 11, 12, the pattern can be formed. In such a way, the failure relief and rewriting of partial ROM data can be executed without making the chip large in size.
