Abstract: PURPOSE:To increase the housing space of a first and a second friction means leading to increase in the friction areas of said friction means and stabilize a friction damping performance by connecting a pair of sub-plates to each other by means of a claw which extends from one of them to the other. CONSTITUTION:When the torque of an engine is transmitted to a clutch disk, a low friction means 27a is operated generating a friction torque F1 and a friction damping action of a first stage I is carried out and, when drive plates 4a, 4b are rotated by a defined angle theta1, a friction damping action of a second stage II is carried out.

Title: Self-aligning current constriction type semiconductor light emitting element
Inventor: YAMAMOTO MOTOYUKI
IPC: H01S5/00
Filed: 1985-09-02
Abstract: PURPOSE:To improve characteristics and mass-producibility of a light emitting element by a method wherein, when a recessed part on a GaAs substrate is etched, the width and the depth of a stripe is measured beforehand and the oscillation is so controlled as to realize single horizontal mode by grown thickness of an N-type cladding layer. CONSTITUTION:After a part of a photoresist on an N-type GaAs substrate 12 is removed with the width of 2mum, the substrate 12 is etched by an etchant with strong selectivity to form a stripe 19 with the depth of 1mum and the width of 35mum. On this substrate, an N-type Ga0.6Al0.4As cladding layer 13, an N-type Ga0.95Al0.05As active layer 14, a P-type Ga0.6Al0.4As cladding layer 15, an N-type Ga0.6Al0.4As cladding layer 16, a P-type Ga0.6Al0.4As cladding layer 17 and a P-type GaAs ohmic layer 18 are successively made to grow. A horizontal mode is controlled by the width (d) of a light emitting region and determined by the width W of the bottom of the stripe on the substrate and the thickness (l) of the cladding layer 13 and an angle theta. The angle theta is constantly 47 deg. from experience and the relation d=W-2l/tan 47 deg. exits. If the width W is measured beforehand, the laser which oscillates single horizontal mode can be controlled by the grown thickness (l) of the cladding layer 13.

Inventor: SHIMADA HIDEAKI
IPC: H04J13/00
Filed: 1987-07-31
Abstract: PURPOSE:To simplify the device constitution of a small sized station by providing a sending means sending a prescribed spread code addressed to each small sized station to a base station and providing a recovery means recovering the spread code from the reception signal and a storage means storing the recovered spread code so as to apply spread modulation by the recovered spread code to the small sized station. CONSTITUTION:Transmission information fed to base station data input terminals 151-15l is inputted to corresponding scramblers 161-16l in the base station. A data synthesizer 17 receives each output of the scramblers 161-16l and sends them to a modulator 18 while giving time division multiplex. Then the reception signal demodulated by a demodulator 17 in the small-sized stations 11-1n enters a data demultiplexer 8, where the spread code at the head is demultiplexed from the succeeding scramble signal. The spread code is sent to a buffer 6 and the succeeding scramble signal is descrambled by the spread signal stored internally and original transmission information is extracted and decoded. Thus, the transmission information is sent to the base station in the spread spectrum system similarly as a conventional system even when no spread code generator is provided in the small sized station.

Title: Radio zone identification system in mobile communication
Inventor: SAKAMOTO MASAYUKI
IPC: H04B7/26
Filed: 1986-08-18
Abstract: PURPOSE:To apply highly accurate zone identification by segmenting an information signal sent from a base station into plural frames, compressing them timewise and sending an identification signal while utilizing the gap time. CONSTITUTION:An information signal 1 such as a sound signal is segmented into lots of frames 2-6 at a prescribed period T0, they are subjected to time compression to form compressed frames 12-16 having the time length of T and a signal 11 subjected to time compression is given to them. Thus, the timewise gaps 21-24 whose length is T0-T are produced among the frames 12-16, zone identification signals 230-233 are provided sequentially at each gap and the result is sent from the base station. Thus, when the sending of the identification signal to each zone is finished, the cycle is repeated again, the mobile equipment uses a zone identification reception circuit so as to received them and when the zone is its own existing zone, the result is informed to the base station to start transmission/reception. Thus, the identification accuracy is improved, the reduction in the zone radius is attained to make the titled system suitable for the large capacity mobile communication system.

Title: Spectral shift operation of boiling water reactor and controlling apparatus therefor
Inventor: MASUHARA YASUHIRO
IPC: G21C7/27
Filed: 1989-07-27
Abstract: PURPOSE:To make it possible to avoid a rise in output of a reactor by making a control so as not to lower the liquid level of a coolant in a water rod below a specified level during a spectral shift SS operation. CONSTITUTION:A control of a core output is executed at the height of a liquid level 30 of a coolant during an SS operation, and therefore the output control by a control rod 4 is unnecessary. However, when a pressure inside a core rises due to interruption of a load, for instance, a pressure difference occurs between the inside of the core and that of a water rod 16, cooling water is thereby made to flow into the water rod 16 to cause a rise in the liquid level 30, an apparent void rate in the upper part of a fuel assembly decreases rapidly, a reaction proceeds to a large extent, and the output increases. On the occasion, the tendency of the rise in a liquid surface is weak as the initial level 30 is high, and the tendency of the rise decreases contrariwise when the initial level is as high as about 3 m or above, that is, about 0.76 times as high as the full length of the water rod 16. By limiting the level 30 to be within this range of condition by controlling a circulation pump, and by conducting a normal operation in this state, accordingly, the rise in the level due to the interruption of the load or the like can be suppressed and thus a sharp rise in the output can be avoided.

Title: Transmission type screen
Inventor: KAWASAKI KATSUICHI
IPC: G03B21/62
Filed: 1988-08-03
Abstract: PURPOSE:To obtain a transmission type screen excellent in resolution and producibility by constituting a lenticular lens unit of a linear Fresnel lens. CONSTITUTION:The lenticular lens unit is constituted of the linear Fresnel lens. Average plate thickness and the plate thickness of the thinnest part are almost equalized. In view of resolution, the pitch of a Fresnel lens in the lenticular lens unit is desirable to be one fifths or less of the lenticular lens unit. When a light absorbing coating film is formed on the observation side surface of the transmission type screen, each tilt angle of the linear Fresnel lens is desired to be set so as to condense light beams on one point on the observation side surface. Thus, the transmission type screen excellent in resolution and producibility can be obtained. Moreover, cracking can be prevented when the light absorbing coating film is formed. The lives of a roll and a metallic mold can drastically become longer.

Filed: 1996-07-04
Abstract: PROBLEM TO BE SOLVED: To facilitate the fastening and loosening of a boot to and from a base plate by providing an ankle strap attached at its lower end to a high back and a lock means for releasably locking a tilt rearward of the high back. SOLUTION: A boot 1 for a snow board is located at a normal sliding position when a high back 2 is forward bent. When a lever 14 is depressed downward, a wire 12 slacks so that the high back 2 can be rearward inclined. With this arrangement, the boot 1 can be easily loosened from the base plate 14 in order to take a walking position without disengaging the ratchet belt 8 of an ankle strap 4 from a ratchet pawl 9. Further, only when the high back 2 is inclined forward and the lever is pushed upward, the boot 1 can be fastened so as to take a sliding position.
