Abstract: PURPOSE:To prevent a defect of data caused by a transmission delay and to increase the transmission speed in the data transmission system comprising plural controllers. CONSTITUTION:A message used for data transmission consists of a SOM field indicating the start of the message, a DATAID field representing an identifier of data, a DESNODE field representing a destination of the data, a DATA being data to be sent, an FCS field representing the result of error check calculation, an ACK field for acknowledge of reception and an EOM field representing the end of the message. The DATAID field consists of the identifier and idle bits, and the ACK field consists of bits for reception acknowledge and idle bits. Since idle bits are provided to the fields, even when a transmission delay in data is not negligible, arbitration and acknowledge of reception are accurately implemented.

Title: Manually tearable fabric
Inventor: SAIGA ISAMU
IPC: C09J7/02
Filed: 1987-06-09
Abstract: PURPOSE:To obtain proper hardness necessary for working and favorable manual tearability by a method wherein the tenacity of multifilament warp and the tenacity of bonding are set within specified ranges. CONSTITUTION:In a laminated fabric produced by laminating a polyethylene film through adhesion to a woven fabric, the woven fabric is made of multifilament and the tenacity of multifilament warp is made to be 300-400 g/multifilament, and further the tenacity of bonding is made to be 1000-2000 g/inch. If the tenacity of multifilament warp is below 300 g, the tenacity necessary for manually tearable fabric is not enough. If said tenacity exceeds 400 g, the manual tearability deteriorates. In addition, if the tenacity of bonding is below 1000 g, the manual tearability deteriorates. If the tenacity just mentioned above exceeds 2000 g, the resultant fabric becomes too hard to be practically handled. Further, the preferable elasticity of the multifilament is 12-18 %. Furthermore, the hardness of the woven fabric measured by cantilever method is desirably 5 mm or more after resin impregnation treatment.

Filed: 1979-11-06
Abstract: PURPOSE: To minimize temperature dependency in hydrogen gas sensor and also make it thermal-resistant by coating three different types of compounds within specified composition limits such as manganese oxide, magnesium oxide and cobalt oxide on porous substrate as sensitizing agents.  
     CONSTITUTION: Sensitizing agent containing compound oxide consisting of 7W 15mol% of manganese oxide and 25W73mol% of cobalt oxide is applied to form a coat on alumina surface. Substrate 1 (porous alumina, apparent specific gravity thereof is approximately 3.1) is immersed in aqueous solution of 1mol/liter of nickel nitrate, dried and thermally treated. This operation is repeated three times and then said substrate is baked so that layers of nickel aluminate and nickel oxide are formed on its surface. Next, platinum line 3 is temporarily applied on the surfacial edge of the substrate, using a paste of platinum powder and glass powder, and electrode 2 is fixed by baking. Follwing these procedures, this base plate 1 is immersed in the above-mentioned sensitizing agent, dried and prebaked at 400°C. After this immersion and prebaking operation are repeated 5 times, final baking at approximately 1,000°C is carried out. Thus an excellent sensor provided with almost constant electric resistance and maintaining unchanged resistance value even repeating thermal cycle is obtained.

Title: Pilot-pressure indicating washer
Inventor: EI KUREIGU FUTSUDO
IPC: F16B31/02
Filed: 1994-06-24
Abstract: PURPOSE: To prevent early collapse of protuberances at the application of compressive load by forming a mass concentration consisting of protuberances each having a predetermined length and indentations between two separate areas on the front and back of an annular body. CONSTITUTION: This pre-load indicating washer comprises an annular body 20 and a plurality of pairs of protuberances 26 and indentations 30. The pre-load indicating washer has a radius of curvature where the mass of material is concentrated along central regions between the inner surface 46 of each indentation 30 and the outer surface 36 of the associated protuberance 26 and between the outer wall parts 38, 40 of each protuberance 26 and the inner wall parts 48, 50 of each indentation 30. Thus, the thickness of material between the inner surface 46 of each indentation 30 and the outer surface 36 of each protuberance 26 is less than at the central region of the combination of each protuberance 26 and each indentation 30. Therefore, the protuberances 26 are elastically deformed and pushed into the indentations 30 during the application of compressive load and do not undergo plastic deformation, whereby premature collapse of the protuberances can be prevented.
