Title: Method of plating flat part of top and under surfaces of narrow width piston ring
Inventor: MURATA KATSUHIRO
IPC: C25D17/08
Filed: 1979-10-15
Abstract: PURPOSE: To prevent the disengagement of a piston ring during power supplying by forming a concave groove on the inside peripheral surface of the piston ring and fitting a power supply contact into this.  
     CONSTITUTION: At the time of plating the top and under surfaces A, B of a piston ring 1, a concave groove 7 is provided to its inside peripheral surfaces to improve the contact with the end 8 of a cathode contact means 3 holding the piston ring 1 in plating soln. This piston ring 1 is held in the plating soln. 5 by the contact means 3, and with this as cathode, it is dipped for a fixed time, after which the power is supplied by an electric power source 2, whereby plating is performed. Since the end 8 of the contact means 3 is held in place in the concave groove 7 of the inside peripheral surface D of the piston ring 1, the disengagement during handling does not occur.

Filed: 1988-06-01
Abstract: PURPOSE:To obtain a solder joining high in reliability by a method wherein a metal wire mesh excellent in a solder wetting property is interposed between an electrode and a transistor of a substrate as a solder reinforcing material. CONSTITUTION:A thick film silver-palladium electrode 2 is formed on an alumina substrate 1 through printing, and a transistor 5 used as a power transistor of a power circuit is mounted flat on the electrode 2 interposing a metal wire mesh 4 between them. And the metal wire mesh 4 is formed through such a manner that a marketting solder absorbing wire is cut conforming to the size of the transistor 5. A soldering method, such as a solder printing method or a mesh receiving soldering method, is used for soldering and the both the methods are capable of joining and possessed of a self-aligning effect, so that the deviation of a transistor 5 mounting position does not need to be corrected. By these processes, solder containing a metal wire mesh is excellent in strength and almost free from cracks even if a thermal stress is applied. And even if cracks occur, the disconnection hardly happens as a metal wire mesh is interposed.

Title: Base paper for thermal screen printing press
Inventor: ODA MASATAKA
IPC: B41N1/24
Filed: 1986-06-09
Abstract: PURPOSE:To obtain an inexpensive high quality image, by forming the title sheet from a thermoplastic resin film forming perforations by heating and the striped fiber support stuck to either one of both surfaces of said film. CONSTITUTION:The base paper for a thermal screen printing press consists of a thermoplastic resin film forming perforations by heating and the striped fiber support stuck to either one of both surfaces of said film. As the thermoplastic resin film, for example, a polyester film is used. The striped fiber support is formed, for example, by arranging nylon fibers each having a diameter of about 40mum at intervals of about 150mum in a stripe pattern and laminating a polyester film with thickness of about 2mum to said fibers. Before the fibers and the film are laminated, an adhesive is applied to the surfaces of the fibers on the side stuck to the film. In this case, the interval between the fibers is made sufficiently wide so that molten toner particles do not enter the gaps between the fibers by a capillary phenomenon. Each of the parallel gaps between the fibers is formed into a elongated groove shape. By this method, the base paper can be formed easily and inexpensively and, further, an original form formed of said base paper is used to obtain sharp screen printing copy.

Filed: 1991-06-04
Abstract: PURPOSE:To eliminate the deviation of the retrieving time caused by the deviation of the number of data retrieved in a subgroup in 8 data retrieving system applying a hash method. CONSTITUTION:The retrieval data (normal retrieval data) in number of pieces almost equal to the key value of the data retrieved in the subgroups sorted by the hash arithmetic are stored in a retrieval memory 4b1 for each subgroup. Meanwhile the remaining retrieval date (overflowed retrieval data) included in each subgroup are stored in an auxiliary retrieval memory 4b2 for each subgroup. Then both memories 4b1 end 4b2 are actuated in parallel with each other to retrieve the data. In such a constitution, a part of the data (overflowed retrieval data) is retrieved by the memory 4b2 in parallel to the memory 4b1 for the subgroup having a large number of retrieval date. Thus the date retrieving time is shortened.

Abstract: PURPOSE:To grasp accurately a temperature of a wafer, by providing a detector for detecting radiant light from the surface to be detected, a mask having many light transmitting openings and a lens means for forming an image of the surface to be detected on the surface of the mask. CONSTITUTION:A mask 7 bored many minute openings between a detector 8 and a wafer 1, is arranged and the image of the wafer 1 is formed on the mask by a lens 9. On one hand, an SN ratio as a whole is improved extraordinarily because infrared rays radiated from a high temperature part are made incident to the detector 8 without damping almost only at the timing when the high temperature part is reached to the position of the minute opening. On this occasion, because the position of the minute opening corresponds to the position of each part on the wafer, the minute opening of the mask from which each date stored in a storage device 12 is obtained and the position of the wafer to which each data corresponds, are known by investigating preliminarily the position of the minute openings where the high temperature parts pass successively, accompanied by electron beam scanning.

Abstract: PURPOSE:To execute a separation to one character even if a contact is generated between characters by forecasting by a character pitch a separated position of a character group image which has generated a contact, and correcting the separating position by referring to a blank information of an adjacent other character-string image. CONSTITUTION:A scanner 1 scans optically a character-string image, converts it to an electric signal, quantizes it and writes it to a character-string image memory 2. A character lump extracting device 3 extracts successively a position, a width and a height of a character image (hereinafter called a character lump) which can be separated by a space, to each character- string unit from the memory 2, and stores them in a character lump information register 4. A character pitch detecting device 5 measures a character pitch by using an information of the register 4. A contact character lump detecting device 6 reads out successively a width of a character lump of the contents of the resister 4, compares it with the character pitch, and when it is detected that plural characters are contained in the character lump, its position, width and height are transferred to a separated position calculating device 7. The device 7 begins with the initial part of the character lump, calculates a candidate example position to be divided in the next time, calculates the upper and lower limit values of a separable section from said result and a prescribed allowable width, and executes a correction.

Abstract: PURPOSE: To previously prevent a fault due to the malfunction, by adding a redundant signal for checking of rightfulness to a figure code following address characters M, S and T that show the types of functions.  
     CONSTITUTION: An M function sending circuit 20 sends figure codes c 1 Wc n  following an address character M, if supplied, to the receiving side via a parity adding circuit 21 and a transmission line. The circuit 21 produces a parity check signal to transmit it to the receiving side. At the receiving side, a parity checking circuit 24 performs the checking based on the figure codes and the parity check signal. Then an M function is carried out when the rightfulness is decided. When the wrongfulness is decided, an alarm signal is delivered to inhibit the operation at the machine side.  In the same way, the S and T functions can be performed. In such way, the assuredness is increased for the M, S and T functions at the same time to previously prevent a falut due to the malfunction.
