Title: Variable-wavelength element
Inventor: OKAYAMA HIDEAKI
IPC: H01S5/12
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To easily control the wavelength of a variable-wavelength element by constituting the element in a 1/4-period shifting structure in which first and second super-period gratings are connected to each other in a state where the gratings are shifted from another by the 1/4 of the grating period corresponding to the center wavelength. SOLUTION: When both gratings 23 and 25 of a variable-wavelength element reflect at the same wavelength (λ0 ), a waveguide 13 constitutes a resonator as a whole. Since a 1/4-period shifting structure 27 is provided, the structure of the element becomes the same as that of a DFB having a 1/4-shifting structure from the wavelength λ0 . Therefore, when this element is used as a semiconductor laser, the element oscillates at the wavelength λ0 and, when the element is used as a wavelength filter, the element can select the light having the wavelength λ0 . The oscillation wavelength of the element can be controlled easily when the reflecting wavelengths of the gratings 23 and 25 are variably controlled by supplying control currents It1 and It2 to the element respectively through electrodes 19a and 19b.

Title: Hopper for horizontally discharging rodlike works in longitudinal array
Inventor: YOSHIDA AKIRA
IPC: B65G65/34
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To prevent rodlike works which are horizontally arranged and stacked in a hopper from being disturbed in the longitudinal direction in the vicinity of a discharge port by fixing a plurality of weights on a lower face of a sheet and by placing a sheet for covering an upper face of the rodlike works which can lower by its own weight while pressure-fitting a curved upper face of the rodlike works. SOLUTION: Since horizontally arranged rodlike works 5 drop from a left side viewed toward a discharge port 2, an upper face of the stacked rodlike works 5 is gently tilted and dropped leftward. At this time, a left side of a sheet 8 with a weight 9 fixed presses the stacked rodlike works 5 downward while pressure-fitting the works 5. Therefore the rodlike works 5 move while keeping an arranged state. Then the rodlike work 5 at the lower end of the discharge port 2 is pushed upward by a corner 7a of an octagonal drum 7 rotating counterclockwise, and then it drops from a gap becoming wide at a plane 7b into a discharge path 3. When there remains a small number of the stacked rodlike works 5 above the discharge port 2, they are fed by a belt conveyer 4.

Title: Multiprocessor and its controlling method
Inventor: TAKAYAMA KOICHI
IPC: G06F1/04
Filed: 1998-10-06
Abstract: PROBLEM TO BE SOLVED: To prevent useless power consumption in an operation stop state by stopping a clock in each processor connected to a network at the time of detecting a continuous stop state for fixed time in the processor itself. SOLUTION: Load data inputted from a network to a processor 1-m are received through an interface unit 13 and a specified process is executed by an instruction execution control part 11. At the time, an instruction idle counter 12 monitors the instruction issuing state of the control part 11 and counts the instruction execution stop time of the processor 1-m. When continuous stop time of fixed frequency is detected on the counter 12 after the completion of the process, a VPU 16 judges the idle state of the processor 1-m and allows the unit 13 to set up a processor state flag 131. Therefore clock distribution control part 14 stops clocks to be distributed to the control part 11, a cache 15 and the VPU 16. Thus, power consumption can be reduced.

The thermal capacity when the respective brakes are in operation is calculated by the controller 9 on the basis of the load signal of the load sensor 11, and the alarm signal is generated when the brake thermal capacity of one hour after the counting is started approaches the allowable thermal capacity ET, and the stop signal is generated when the brake thermal capacity reaches ET. The arrangement allows the alarm signal and the stop signal to be generated before the temperature of the brake becomes abnormally high.
