Patent JP-S63294029-A (JP)
Title: Bus type communication network
Inventor: OGUCHI NAOHISA
Filed: 1987-05-26
Abstract: PURPOSE:To improve the communication throughput by accessing first and second busses in the CSMA/CD system where plural nodes confirm the reception response and adding a preamble signal different in length by nodes to the start of a transmission packet. CONSTITUTION:When two or more nodes simultaneously transmit packets, the preamble signal different in length by nodes is added to the start of each transmission packet. Each node transmits the data packet in accordance with prescribed procedures and transmits the preamble signal and confirms the presence or the absence of collision on a bus thereafter. In case of the occurrence of collision, a bus BS2 is accessed to transmit the packet again if a bus BS1 is accessed, and transmission is queued till busses are idle if the bus BS2 is accessed. That is, if two or more nodes detect idle states of busses BS1 and BS2 together to start transmission, the node whose preamble signal is longest acquires the bus, and the node whose preamble signal is shortest detects collision to access the bus BS2. Further, the reliability of the whole of a communication network is improved because of dual busses BS1 aud BS2 and dual transceivers Ti1 and Ti2.

Abstract: PURPOSE:To enable to perform a reliable self-alignment for the titled MOSFET by a method wherein an oxide Mo film is obtained by oxidizing a part of the surface of the Mo layer which will be turned to a gate electrode, and a self- aligning method, in which said Mo film is used as a mask, is used. CONSTITUTION:An oxide Si film 2 and an Mo layer 3 are laminated successively on the surface of a p type Si substrate 1. Then, an oxide Mo film 4 is formed on the surface of the layer 3 by oxidizing a part of the surface of the layer 3. A patterning is then performed only on the part which will be turned to the gate region of the MOSFET, leaving the layers 3 and 4. Then, a p type source 5 and a drain 6 are formed by implanting a p type impurity ion into the substrate 1 by performing a self-aligning method using the films 3 and 4 which were left over by patterning. The layer 3 is then exposed by removing the layer 4, and this exposed layer 3 is used as a gate electrode. Accordingly, a reliable self- alignment can be performed and, as a result, the MOSFET, which has Mo as a gate electrode, of stabilized characteristics can be obtained.

Title: Linear guiding device
Inventor: KAWAGUCHI TAKAHIRO
IPC: B23Q1/40
Filed: 1990-05-21
Abstract: PURPOSE:To facilitate formation of holes for no load running of rolling members by constituting a linear movement guide device of a block main body having a load running face at the fore end part of the bearing part of its bearing block, ball running hole forming plates for forming the no load running allowing holes and a cover for forming rolling member return passages. CONSTITUTION:No-load running allowing holes of bearing block B are formed by attaching plates 5 for forming rolling member running holes. Working grooves in which rolling members 2 roll at one of or both members facilitate the formation of no-load running passages, thereby facilitating construction of a long-sized baring unit. Since the block is formed by attaching the plate 5 and a cover 4 to the main body 3, the main body 3 can be formed symmetrically in the vertical and lateral directions and through a drawing work the long-sized block main body 3 can be formed. Furthermore, since the plate 5 serves as one side of the non-load running passages, the generation of striking sound of the rolling members can be prevented by forming the plate 5 from resin.

Title: Wave-absorbing structure body
Inventor: WATANABE TAKAHIKO
IPC: H05K9/00
Filed: 1990-05-21
Abstract: PURPOSE:To ensure high reliability, light weight and high strength and to enhance a wave-absorption characteristic by a method wherein conductive fibers are used and this structure body is constituted of a fiber-reinforced composite material whose reinforcement material is a three-dimensional fabric whose conductivity has a grade from one side to the opposite side. CONSTITUTION:At a reinforcement material 7 composed of a three-dimensional fabric, conductive fibers 8a are used for the X-axis 7a and the Y-axis 7b out of the X-axis 7a, the Y-axis 7b and the Z-axis 7c; and the conductive fibers 8a and nonconducting fibers 8b are combined and used for the Z-axis 7c. At a wave-absorbing structure body, the content of the conductive fibers 8a is low near the surface 9a of the structure body 10. Consequently, since a dielectric constant epsilon is low and nearly equal to that of the air, incoming radio waves are not reflected on the surface 9a of the structure body 10 and are taken in the structure body 10, i.e., an absorption layer 1. As the taken-in radio waves progress to the inside, they flow effectively into the conductive fibers 8a as an electric current because the content of the conductive fibers 8a becomes high and their conductivity rho becomes large. They are attenuated by their ohmic loss and absorbed.

Abstract: PROBLEM TO BE SOLVED: To prevent frequent repeated operation of a suction pump by stopping the pumping operation upon elapsing a predetermined time after starting the pumping operation if switch off level in an oil sub-tank is detected within a predetermined time range. SOLUTION: Pumping of oil from an external oil tank 70 to an oil sub-tank 60 is started by a suction pump 80. When a float 63a detects switch off level in the oil sub-tank 60, pumping operation of the suction pump 80 is stopped upon elapsing a predetermined time after starting the pumping operation if the time elapsed before detection falls within a predetermined time range, i.e., an ordinary average detection time. Since frequent on/off operation of the suction pump 80 can be suppressed, durability of the suction pump 80 and a float switch 63 can be enhanced.
