IPC: H04M19/00
Filed: 1989-01-20
Abstract: PURPOSE:To limit power consumption in a two-wire power receiving channel board only to the one caused by a loop current by performing power supply by separating the loop current from a telephone exchange by using a DC-DC converter. CONSTITUTION:When the two-wire power receiving channel board 6 is being used, a closed loop state is set between a chip wire 9 and a ring wire 8 by a DC loop signal sending circuit 1, then, the loop current flows. The current is separated from a loop by a DC-DC switching circuit 2, and a voltage of positive side is applied on the anode terminal of a first diode 4. By setting the output voltage of the circuit 2 higher than that of the power source 7 of a local station de vice, the power source of the internal circuit 3 of the two-wire power receiving channel board is supplied from the circuit 2 via the diode 4 at the closed loop state. When an open loop state is set by the DC loop signal sending circuit 1, no loop current flows between the chip wire 9 and the ring wire 8, and the output voltage of the circuit 2 goes less than that of the power source 7.

Title: Suction opening and vacuum cleaner with such suction opening
Inventor: ICHINO TAKEYUKI
IPC: A47L9/02
Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To obtain a suction opening that has a good draining property for a space outside a suction air course in the suction opening and is suited to washing with water in whole, in the suction opening where a suction air course connecting continuously a connecting pipe and the suction opening, is formed inside the suction opening. SOLUTION: When a stained suction opening is removed from an extension pipe and washed with water in whole, water enters into a space outside the suction air course from a joint between an upper case and a lower case 12 and a gap between a brush and the facing walls 22, 23 of a brush mounting groove 21. In such a case, as drain holes 38, 39, 40 are formed at the bottom, by putting the suction opening on a flat place as when it is used with the bottom faced down, water gathers at the bottom of the space and goes out from the drain holes 38, 39, 40. Thus water is kept from remaining inside the suction opening for a long time. As there is no upward opening, there is no possibility that dust gathers through the drain holes 38, 39, 40.

Filed: 1989-01-20
Abstract: PURPOSE:To realize a laser having high oscillation efficiency by providing multiple well layers within a semiconductor layer structure such that widths of the wells are decreased gradually from the electron injected side and that the wells have the same quantum units. CONSTITUTION:A semiconductor layer is produced by forming a clad layer 2 of one conductivity type, multiple quantum well layers 5-7, a clad layer 8 of the opposite conductivity type and a contact layer 9 on a substrate 1 sequentially in that order. The well layers 5-7 are formed such that widths of the wells are decreased gradually from the electron injected side towards the center of the device. Further, the wells 5-7 have different compositions from each other so as to align quantums of the wells with each other. Accordingly, injected electrons are stored uniformly in the quantum wells 5-7 and a laser presenting a high oscillation efficiency can be realized. Such laser is accomplished by forming electrodes on the lower face of the substrate and on the upper face of the contact layer 9 and cleaving the substrate 1 at a length of a resonator.

IPC: C21D7/02
Filed: 1978-02-08
Abstract: PURPOSE:To obtain a damping material with high damping capacity by cracking the surface layer of a metellic material to different depths to enhance the mechanical stability of the surface layer. CONSTITUTION:Deep grooves 10, 12 and shallow grooves 9, 11 are alternately cut in surface layer 8 of metallic material 7 before rolling. This material is rolled to form metallic material 26 having joints 18-25 of inverted T-shape. Since base traces 22-25 are at different depths, they are not connected. Accordingly, the no. of cracks per unit length can be increased as compared to a conventional method. When material 26 undergoes bending vibration, sliding motion is brought about at the joints of cracks 18-21 and base traces 22-25, and the vibration energy turns to thermal energy owing to the friction and disappears in a remarkably enhanced ratio. Thus, a damping material is obtd. having a surface layer with high damping capacity, no exfoliation and mechanical stability.
