Filed: 1996-11-21
Abstract: PROBLEM TO BE SOLVED: To eliminate an electric mechanism in a water drop mechanism so as to easily use the water drop mechanism by providing with a water drop pipe formed in such a constitution that an impeller upper part and a delivery pipe upper part communicate with each other and a small hole is drilled on its lower part, and a water drop valve which is closed by water pressure in the delivery pipe arranged between the impeller of the water drop pipe and the small hole and which is opened by water pressure of the upper part of the impeller. SOLUTION: An upper part of an impeller 1 and an upper part of a delivery pipe 2 are connected to each other through a water drop pipe 3, a water drop valve 4 arranged in the water drop pipe 3 is opened/closed by a pressure difference between both parts. When a water level is reduced by a drain operation and an operation is transferred to a stand-by operation, the water drop valve 4 is opened, and remaining water in a pumping pipe 5 drops down. Since an upper part of a delivery pipe 2 is high pressure more than an upper part of the impeller 1 during normal drain operation, the water drop valve 4 is closed.  Since pressure in an upper part of the delivery pipe 2 is reduced at the time of the stand-by operation and the upper part of the impeller 1 is high pressure more than the inside of the water drop pipe 3, the water drop valve 4 is opened, and water in the pumping pipe 5 drops down. It is thus possible to eliminate an electric mechanism in a water drop mechanism so as to easily use the water drop mechanism.

Title: Method for recording and erasing information
Inventor: KOBAYASHI TADASHI
IPC: B41M5/26
Filed: 1989-11-30
Abstract: PURPOSE:To obtain an information recording and erasing method capable of performing recording and erasure at high speed by forming such a state that an amorphous phase and a non-equilibrium crystal phase are mixed to the laser beam irradiated part of a recording layer and allowing the irradiated part to correspond to a recording state or an erasure state. CONSTITUTION:A substrate 1 is formed from a material such as plastic, for example, polyolefin or glass and a protective layer 3, a recording layer 2, a protective layer 4 and a protective layer 5 are formed thereon in this order. The recording layer 2 is formed from a material capable of generating such a state that an amorphous phase and a non-equilibrium crystal phase are mixed by the irradiation with laser beam. In this state wherein the amorphous phase and the non-equilibrium crystal phase are mixed, the non-equilibrium crystal becomes a nucleus and the amorphous phase is crystallized extremely rapidly. Therefore, recording and erasure speeds can be made high. As a material capable of generating this phase change, there is In-Sb-Te. For example, when the recording layer 2 is formed from In-Sb-Te, a state wherein the amorphous phase and the non-equilibrium crystal phase are mixed appears in a boundary region where the amorphous phase and the non-equilibrium crystal phase appear in such a case that the recording layer is melted and quenched by the irradiation with laser beam and initialization, recording and erasure can be accelerated.

Title: Interferometer
Inventor: YAMADA TAKATOSHI
IPC: G01B9/02
Filed: 1996-11-07
Abstract: PROBLEM TO BE SOLVED: To suppress the effect of disturbance by an arrangement wherein a diffracted light to be measured is converted to have a uniform phase thereby generating a reference light. SOLUTION: A light L2 to be measured from an object is converted through a collimator lens 11 into a converged luminous flux which is then diffracted through a grating 12. A zero order diffracted light L20 is introduced to the light receiving face of a CCD solid state image sensor 15 with the image information from the grating 12 being added to the phase information of an object. On the other hand, a first order diffracted light L21 is converted to have a uniform phase with arranged wave front and introduced to the light receiving face of the CCD solid state image sensor 15 while keeping a predetermined angle with respect to zero order diffracted light L20.  Consequently, the diffracted lights L20 and L21 interfere each other on an imaging plane and a spherical wave is emitted through a pinhole P1 and an interference fringe can be observed with respect to the diffracted light L21 converted through a collimator lens 14 into a plane wave. Since the diffracted lights L20, L21 can generate an interference fringe using a common optical path, effect of disturbance can be suppressed.

Filed: 1987-12-09
Abstract: PURPOSE: To prolong the service life of a relay by providing a timer means for starting timing at the time of receiving the output of a power source voltage detecting circuit and for counting an optional time and a relay driving signal output means for outputting a signal for driving a relay after finishing timing by the timing means. CONSTITUTION: A power source voltage detecting circuit 1 detects some level of the voltage of a power source 13, sets a time desired to time to a timing means 5 and starts timing. The means 5 times a different time every time. When the means 5 finishes timing, the relay driving signal output means 6 outputs the relay driving signal. Since the timing time by the means 5 is different every time, the output timing of the relay driving signal is equally distributed with respect to the phase of power source voltage and the operation points of the relay 8 is not concentrated to one point of power source voltage, thereby the service life of the relay 8 can be prolonged.

Title: Semiconductor laser array element
Inventor: ENDO KENJI
IPC: H01S5/223
Filed: 1986-12-29
Abstract: PURPOSE:To improve an transfer speeds and yield by a method wherein a semiconductor multilayer film including an active layer is selectively formed on a semiconductor substrate except where mesas are positioned and a multiplicity of oscillating sections capable of operating independently from each other is constructed of a current constriction structure and an optical waveguide. CONSTITUTION:During a crystal growing process, its growth is blocked on top of mesas by a dielectric coating of SiN or the like formed on top of the mesas, and the growth therefore proceeds only to fill up the regions between the mesas. A blocking layer 7 is locally removed in a stripe geometry along a resonator axis and the resultant groove is filled up with a p-type clad layer 8. This process results in a current constriction structure and in a transverse mode controlling structure wherein a portion of a mode longitudinally distributed from an active layer 5 reaches the blocking layer 7 at both ends of the stripe and sustains loss there. An epitaxially grown layer is divided at mesas on a substrate 1, for the electrical isolation of several laser oscillating sections from each other. P-type electrodes 12 are built respectively for the oscillating sections for the driving of one oscillating section independently from the others.
