Title: Transmission method
Inventor: KAKUNO TAKANE
IPC: H04L12/413
Filed: 1983-12-12
Abstract: PURPOSE:To attain the assured transmission of information signals in a high traffic mode of a CSMA/CD system among plural transmitters, by starting again transmission if a transmission line is idle after detecting the idle state of the transmission line and after waiting for random time. CONSTITUTION:A common part 19 receives an idle state detecting signal from a detection circuit 15 for idel state of transmission line and then starts a waiting time counter circuit 18. The circuit 18 gives an information to the part 19 when the time W elapses. This time W is decided by the priority and the random number of a certain time range. Thus the part 19 checks the presence or absence of the idle state detecting signal and gives the transmission start indication to a transmitter 10 if a transmission line is idle. Then the transmitter 10 starts transmission. While a collision detecting circuit 16 monitors the presence or absence of transmissions of other transmitters by an indication of the part 19 within a period between the start of transmission and a return time point from a star-shaped coupler. Then the circuit 16 delivers a collision signal to the paper 19 as long as a transmission mode continues. Receiving the collision signal, the part 19 stops the transmission of the transmitter 10.

Title: Method of forming insulating film
Inventor: SATO JUNICHI
IPC: H01L23/522
Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To form an SiOF film having excellent hot-carrier resistance and a low dielectric constant. SOLUTION: Plasma CVD is conducted by using a gas containing silicon tetraisocyanate (TICS) and the fluoride of a group oxygen element, and an SiOF film 23 is formed. That is, the taintake of Si atoms following the intake of F atoms into the film is prevented by removing H atoms from the film forming gas and separating an Si supply source and an F supply source. Accordingly, since a dielectric constant is lowered by taking in a sufficient quantity of F atoms while the quantity of Si-OH bonds formed is reduced, the SiOF film 23 also having superior moisture resistance and hot-carrier resistance is acquired. OF2 , SeF4 and TeF4 are used as the fluorides of group oxygen elements, but unreacted components not related to film formation are removed quickly to the outside of a system because these compounds are sublimated ones.

Title: Floating type magnetic head
Inventor: KURIYAMA TOSHIHIRO
IPC: G11B21/21
Filed: 1990-09-04
Abstract: PURPOSE:To obtain constant floating quantity at the inner and outer peripheral sides of a magnetic medium by receiving a floating force higher than that at the outer peripheral side by widening the pressure receiving area of a rail at the inner peripheral side. CONSTITUTION:The width of the rail 2a at the inner peripheral side for the magnetic medium is set wider than that of the rail 2b at the outer peripheral side by prescribed quantity w1, which enables the floating quantity received with the rails at the inner and outer peripheral sides to be set equally. Pressurizing balance can be kept by deviating the pressurizing point of a gimbal from the center part of the slider 1 to the rail 2 side at the inner peripheral side set wider by prescribed quantity w2. Also, it is possible to stably keep the floating of the slider with simple constitution and a low cost by stabilizing the dynamic posture of the slider by forming the whole shape in circular arc shape so as to protrude the center parts of the rails 2a, 2b.

CONSTITUTION:The tip of the swelling 5a of a Dumet wire 5 and the end of a cathode 3 made of a semiconductor ceramics where a silver electrode 6 is formed beforehand by the baking or the vacuum evaporation are arranged in a glass tube 4 on condition that the both members are contacted, and heated at 600 deg.C to 650 deg.C in a neutral ambiance such as N2 to seal up the Dumet wire 5 and the cathode 3 in the glass tube 4. Instead of the Dumet wire 5, a metallic wire material such as Ni wire may be used. Since the silver electrode 6 is used to confirm the electric connection of the semiconductor ceramics and the Dumet wire, it can be omitted if the other means is available for the purpose. As the semiconductor ceramics, the valence compensating type semiconductor ceramics, for example, is available. A representative example of the valence compensating type ceramics is a ceramics using a barium titanate system.

Abstract: PURPOSE:To reduce not only an occupying space at the times of use and housing but also the use amount of a liquid, to preserve the liquid as it is and to permit extremely simple behavior in use by forming the upper part of a shoe-shaped container from soft material and tying said part in the vicinity of the opening part thereof by a string to hermetically close the container. CONSTITUTION:A shoe-shaped container 1 composed of water resistant material is formed into a structure openable and closable at the opening part thereof. For example, a hard container 5 in which a foot can be placed is surrounded by soft material to form such a structure that the midway place of said material corresponding to an ankle can be throttled by a string to be closed. The container 1 thus formed occupies a necessary min. volume and a liquid to be used may be reduced and, therefore, the container 1 is efficient from the aspect of housing and use. In use, a liquid is received in the container a size larger than the last of a user and the user's foot may be immersed in said liquid and, after use, the container preserves the liquid as it is by shielding the opening part thereof and can be prepared for the next time. Since the container is hooked with a toe to move together when a foot is raised, extremely simple behavior during use is made possible.

Abstract: PURPOSE:To improve distribution and atomization of fuel in the vicinity of a spark plug by setting the center line of atomized fuel, injected from a fuel injection valve, to cross with a scavenge flow, which flows into a combustion chamber from a scavenge port, further to face in the vicinity of the spark plug. CONSTITUTION:The center line of atomized fuel, injected from a fuel injection valve 17, is crossed with a scavenge flow, which flows in a combustion chamber 16 from a scavenge port 4 through a scavenge valve 11, further faced in the vicinity of a spark plug 8. Thus, by promoting the fuel to mix with the new charge air while sufficiently performing atomization of the fuel, its distribution in a region around the spark plug 8 is uniformly improved with ignition and propagation of a flame improved. Also, most of the fuel is collected to the upper part of the combustion chamber 16, and since the evaporated fuel is well mixed, when it traverses a scavenge stream, in only the scavenged new charge air, exhaust emission and fuel consumption can be reduced almost without mixing the fuel in residual gas staying in a lower part of the combustion chamber 16.

Title: Magnetic disk device
Inventor: MINASE MINORU
IPC: G11B19/06
Filed: 1988-09-20
Abstract: PURPOSE:To accurately detect whether a disk driving motor has an abnormal rotation or not by generating an index signal at each revolution of the disk driving motor and deciding the interval between an index signal and the next index signal. CONSTITUTION:When a head 6 is stopped at a recording cylinder of a disk 3, the index signal is inputted to a control part once or more whenever the spindle motor 2 rotates one revolution. In this case, the interval of inputting the index signals is a constant interval. Then, when the head 6 under the stopping state on the recording cylinder is operated to seek to the outer circumferential side of the disk, the input interval becomes shorter than a prescribed value, and when the seek of the head 6 is performed toward the inner circumferential side of the disk, the interval is longer than the prescribed value. Now, a correction amt. for the input interval of the index signals is decided in accordance with the seek direction / seek amt. prior to executing the seek operation. Then, a ratio RT is calculated from the correction amt., preset index signal generating intervals and the input time intervals of the index signals during the seek time, and when this ratio falls within the range of specified value, the revolution is regarded to be good enough.
