Date Feb. 14, 1985.In this pipe connection, the pipe end part (5) is pressed, as a result of cold-forming in zones, by means of a press ring (4) to be displaced axially, to form a positive leak-proof connection with a connection piece (1) inserted into the pipe end part and belonging to a pipe fitting (2). A sleeve (3) to be pushed onto the pipe end part is provided with an annular outer bead (7) and, when the press ring is pressed on, is deformed in such a way that the sleeve material is displaced radially inwards in the bead zone (8), the pipe end part and connection piece acquiring an annular recess (9). Moreover, the press ring (4) has at its rear end an annular inner bead (10) which at the same time displaces the sleeve material radially inwards at the rear sleeve end, as a result of which further pressing takes place at the end (12) of the connection piece (1). The gap between the pipe and connection piece is thus closed, so that no crevice corrosion can occur.

Abstract: PURPOSE:To thinly form a capacitor insulating film between an earth wiring and a gate electrode in a SRAM memory cell with excellent uniformity. CONSTITUTION:After an element isolation field oxide film 2, a gate oxide film 2b, and gate electrodes 3a and 3b have been formed on a P-type silicon substrate 1, source and drain 4a, 4b and 4c are formed.

Title: Signal transmitter
Inventor: TSURUMAKI SHINZO
IPC: H03M13/00
Filed: 1994-01-11
Abstract: PURPOSE:To prevent the errors of transmission signals from being generated in a reception part even when a fault is generated in a transmission part and a transmission line by reproducing transmission input signals holding a previous logical value when transmission output signals are turned to a same logical value continuing state. CONSTITUTION:In the transmission part 1, by inverting basic signals corresponding to the change point of the logical value of the transmission input signals, the transmission output signals as biphase logical signals corresponding to the logical value are generated. In the reception part 2, the biphase logical change point of the received transmission output signals is detected and further, the signals are converted into the signals for which reception clock signals alternately appear. Then, the transmission input signals are reproduced from the relation of the rising point of time of the signals and the received transmission output signals. When the fault is generated in the transmission line and the transmission output signals are turned to the state of continuing the same logical value, the reproduced transmission input signals hold the previous logical value and the detection error of the transmission output signals is prevented.

Title: Information recording medium and recording method
Inventor: SUZUKI KATSUMI
IPC: G11B7/24067
Filed: 1997-01-08
Abstract: PROBLEM TO BE SOLVED: To make it possible to arbitrarily select an erasable recording method and unerasable recording method, by providing the information recording medium with a first dielectric layer having a m.p. higher than the m.p. of a phase transition recording layer and a second dielectric layer having a m.p. between the m.p. of the phase transition recording layer and the first dielectric layer. SOLUTION: The information recording medium 10 is irradiated with a laser beam 20 from a transparent substrate 11 side. The power of this laser beam 20 is adjusted to the extent of sufficiently melting the phase transition recording layer 12 and not melting the second dielectric layer or semiconductor layer 14. Then, the occurrence of evaporation or holding in the irradiated parts 21 of the molten phase transition recording layer 12 is averted. Next, the irradiated parts 21 are rapidly cooled and the phase transition from the crystalline to amorphous phase is induced by stopping the irradiation with the laser beam 20. The crystalline parts and amorphous parts are formed in the phase transition recording layer 12 to induce a difference in the reflectivity in such a manner, by which the erasable recording is made possible.

Title: Driver and leans unit employing it
Inventor: SUZUKI TAKASHI
IPC: G02B7/04
Filed: 1996-01-09
Abstract: PROBLEM TO BE SOLVED: To shorten the overall thrust length of driver as much as possible by arranging a rotary member and a detection means within the thrust width of an oscillation wave drive means. SOLUTION: Upon rotation of a ring 19, a speed increasing gear 26 meshing a face gear part 19b disposed in the ring 19 rotates to cause rotation of a pulse plate 27. Rotation of the pulse plate 27 is detected by a photoelectric transmission switch 28 and the ring 19 is turned by a rotational angle designated based on a detection signal thus controlling the movement of a lens. In a conventional oscillation wave motor, inside diameter of an oscillation member 11 is larger than the inside diameter of rotor part (circumferential moving member 16, a rotary cylinder 17 and a rubber ring 18), and a dead space is formed between the inner circumference of rotor part and the outer circumference of a cylindrical body 7.  When a rotation detecting means comprising the speed increasing gear 26, the pulse plate 27 and the photoelectric transmission switch 28 is contained in the dead space, space efficiency is enhanced without increasing the size.

Filed: 1998-01-07
Abstract: PROBLEM TO BE SOLVED: To obtain a measuring method in which softening amount and frost heaving amount due to a freezing operation and a melting operation of chemically or physically stabilized and treated soil can be measured, by a method wherein the chemically or physically stabilized and treated soil is put into a container while a compacting action is being applied, a lid is put so as to airtightly seal the container and a freezing action and a melting action are repeated alternately so as to measure the softening amount and the frost heaving amount. SOLUTION: Stabilized and treated soil 1 is put into a container 1 up to the surface of a container 1 while it is being compacted by a rammer in the compacting test method of soil as a soil-quality test method, and the surface of the container 1 is finished horizontally. A lid in a depth of about 10 cm is put on the created specimen, and the container 1 is airtightly sealed sufficiently. Regarding the temperature and the time of the freezing action and the melting action of the specimen, one cycle as a reference is constituted in such a way that the specimen is frozen for 24 hours at -15 deg.C by a refrigerating machine and that the specimen is melted for 24 hours at +15 deg.C by a fusing machine, and up to 15 cycles are repeated. As the freezing cycle and the melting cycle progress, the specimen is swollen. Its swollen part is measured as a frost heaving amount.  At this time, the frost heaving amount after the melting action does not contain frost columns. Consequently, it is required to pay attention to a fact that the frost heaving amount becomes smaller than the frost heaving amount in the freezing action.
