Title: Clutch cylinder member and viscous coupling
Inventor: WATANABE KAZUYOSHI
IPC: F16D35/00
Filed: 1989-01-31
Abstract: PURPOSE:To facilitate working of a clutch cylinder member, and to enable a high dimensional accuracy to be obtained by individually fixing clutch cylinder members, each of which has been made up of a separate member whose thickness is reduced toward both ends, to a housing member. CONSTITUTION:In an erasing chamber 31, 33 in which silicon oil is hermetically filled, a plurality of cylindrical clutch cylinders 37, 39 which have been alternately arranged in the radial direction are provided. The cross-sectional shape of a clutch cylinder member 41 is of a straight taper shape in which thickness decreased from the straight part 43 toward both ends. Each of the clutch cylinders 37 on the output member 11, 13 sides is made by equally cutting the clutch cylinder member 41 at the straight part 43. And, in the clutch cylinder 39, the left side blade 51 out of the comb-toothed blades 51, 53 formed by slitting in parallel both ends of the clutch cylinder member 41 is inserted into a through hole 55 provided in a flange member 5, and is fixed thereto.

Title: Information recording medium
Inventor: OKAWA HIDEKI
IPC: G11B7/2433
Filed: 1988-02-01
Abstract: PURPOSE:To suppress generation of the phase transition of a recording layer and to stably maintain the recording layer by forming the recording layer of carbon, hydrogen and metal or semiconductor in such a manner that the activating energy to change the phase thereof X-ray diffractively to an amorphous state is >=2eV. CONSTITUTION:A substrate 1 consists of a resin such as carbonate or material such as glass which is less deteriorated with age. The recording layer formed thereon is the phase formed by extremely finely dispersing the metal or semiconductor in the carbon or hydrogen and is kept X-ray diffractively amorphous. The metal or semiconductor of this layer is effectively protected by the carbon and the hydrogen to enhance the oxidation resistance and stability. The layer changes X-ray diffractively to the phase of the crystal state when the energy such as heat above the prescribed value is applied thereto from the outside. The amorphous state is stably maintained and the high oxidation resistance of the recording layer 2 is maintained long if the compsn. is so adjusted that the activating energy attains >=2eV.

Title: Method for cutting aluminum material by laser
Inventor: ENOMOTO MASATOSHI
IPC: B23K26/38
Filed: 1992-02-05
Abstract: PURPOSE:To improve cutting performance by laser by using pure oxygen or a gas whose oxygen content is larger than air as an assisting gas. CONSTITUTION:A laser cutting device constituted of a laser generator 1, laser torch nozzle 2 and assisting gas supplying part 5 is used, and an aluminum alloy strip W is used as a test piece setting 1mm thickness T1 at one end, 10mm thickness T2 at the other end in the longitudinal direction and with the thickness increasing at a constant grade from the one end to the center part of the strip. In regard to the case of using air and the case of using pure gaseous oxygen as the assisting gas, the pressure of the assisting gas is varied and the laser cutting is performed on the test piece W from the end part small in thickness to the end part large in thickness. Thus, the higher the pressure of the assisting gas, the larger the marginal thickness for cutting. Also, if pure, gaseous oxygen is used as the assisting gas in this case, the marginal thickness for cutting is increased even more.

Title: Rear wheel steering control device for four-wheel steering vehicle
Inventor: SUGIYAMA MIZUHO
IPC: B62D6/00
Filed: 1992-02-05
Abstract: PURPOSE:To provide good turning performance by making up an electric control means of a high frequency component extracting means to extract the high frequency component of a detected yaw rate and a steering control means to steer rear wheels at a steering angle proportional to the high frequency component after outputting a control signal corresponding to the extracted high frequency component to a rear wheel steering mechanism. CONSTITUTION:When disturbance such as side wind is input during turning transition, a low frequency component r* is removed from a detected yaw rate r. Although the absolute value ¦r-r*¦ of a high frequency component r-r* becomes greater, the absolute value ¦r-r*¦ is kept to be almost zero when a vehicle has normal circle turn. As a result, when disturbance such as side wind is input during turning transition, right and left rear wheels RW1, RW2 are steered in the same direction as the turning direction of the detected yaw rate r to provide good running stability for the vehicle. When the vehicle has normal circle turn, the right and left rear wheels RW1, RW2 are not steered to provide good turning performance for the vehicle.
