IPC: H01S5/00
Filed: 1995-07-06
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of a semiconductor laser by suppressing the introduction of misfit dislocation and to suppress the fluctuation of the characteristics of a semiconductor laser by forming a mesa stripe-like shape with accuracy. SOLUTION: A dielectric mask having a stripe-like opening is formed on an n-type GaAs substrate 1 and an n-type Al0.4 Ga0.6 As clad layer 3, an In0.2 Ga0.8 As-SCH active layer 4, a p-type Al0.4 Ga0.6 As clad layer 5, and a p-type GaAs protective layer are successively grown by using a MOVPE method. Then the dielectric mask is removed and an n-type Al0.4 Ga0.6 As buried layer 7 and a p-type GaAs buried layer are grown and an insulating film 12 is deposited on the entire surface. After the film 12 is formed, the film 12 is removed from the part above the stripe and a p<+> -type diffusion layer 9 is formed by doping parts of the buried layers 7 and 8 with Zn by using the insulating film 12 as a mask. After an n-side electrode 10 and a p-side electrode 11 are formed, cleavage is performed.

Title: Steel plate floor panel
Inventor: SHOJI TATSUO
IPC: E04F15/024
Filed: 1997-07-17
Abstract: PROBLEM TO BE SOLVED: To provide a steel plate floor panel capable of having high joint strength of members to be connected in the steel plate floor panel and connecting front member to rear member by calking joint having construction hard to deform a joint section itself. SOLUTION: A calking hole 18 developed by wall section 17 projected to the direction opposite to a front member 2 is formed in contact section 16 to the front member 2 of a rear member 3, and a calking projection 19 projected and formed to the front member 2 is inserted in the calking hole 18. A deformation part 19a having a diameter larger than the calking hole 18 is formed in the front part projected from the wall section 17 of the calking projection 19, and the deformation part 19a is press-contacted to the end face of the wall section 17 to integrate the front member 2 and rear member 3 into a unit. Then, since the wall section 17 developing the calking hole 18 constitutes rib construction for adding strength to the circumference of the calking hole 18, the deformation of the calking hole 18 is prevented, and the strength of a floor panel is increased.

Patent JP-H0356781-A (JP)
Title: Flow control valve
Inventor: ONO ITARU
IPC: F16K47/02
Filed: 1989-07-25
Abstract: PURPOSE:To prevent the occurrence of cavitation bubbles in a flow control valve for a hot water supply unit by closing a valve when source water pressure is high, and controlling a water flow via a throttle passage formed in a gap between a valve body and a valve bearing through a nozzle hole provided in the valve. CONSTITUTION:A flow control valve has a spindle 5 moving when the angle of rotation of a gear becomes large. The area of a gap between a valve 12 and a valve body 6 is thereby made variable, and when water pressure is high, a maximum flowrate is obtained at the small angle of rotation of a gear. The tip of the spindle 5 is always kept off the valve 12 until an intermediate gear comes to have a certain angle of rotation. Also, the valve 12 and the valve bearing 7 are made in contact with each another at a large angle of rotation and only the valve body 6 is made movable back and forth. When water pressure is high, therefore, water passes through a nozzle 11 at the valve 12 and the pressure thereof is reduced. Then, water passes through a gap 9 between the valve body 6 and the valve spring 7, and a flowrate is thereby controlled. According to the aforesaid construction, the occurrence of cavitation bubbles can be prevented and a noise can be reduced.

Title: Radome for antenna
Inventor: ARAKAWA YOSHIHIRO
IPC: H01Q1/02
Filed: 1990-07-20
Abstract: PURPOSE:To make the snow falls on a radome slide down on the outer periph eral surface of the radome and to be accumulated at a place which is far from the lower periphery of the radome so the radome main body can be prevented from being covered with a thick layer of snow by inclining the lower periphery toward the inside of the radome. CONSTITUTION:The lower peripheral section 1b of this radome l for antenna is inclined toward the inside of the radome l and the lower end section of the radome l is fixed by means of brackets 2 fitted to a radome installing surface 2. Then 4 of the figure represents a plate-like antenna. When snow falls on the radome 1, the snow slips down on the outer periphery of the radome 1 and accumulates at a place which is far from the lower peripheral section 1b of the radome l, because the lower peripheral section is inclined inward. Since the snow slipped down on the surface of the radome accumulates in a mountain-like state in the vicinity of the lower section 1b of the radome l, the snow can be removed naturally by air resistances, winds, and vibrations.

Title: Method of demagnetization
Inventor: NAKAZATO HIROSHI
IPC: H01F13/00
Filed: 1988-08-04
Abstract: PURPOSE:To completely demagnetize a magnetized permanent magnet, especially a rare-earth magnet, by a method wherein the material to be demagnetized is cooled down after it has been heated up to its Curie temperature or higher in the state wherein the material to be demagnetized is covered with a magnetic soft material. CONSTITUTION:Material 1 to be demagnetized is cooled down after it has been heated up to its Curie temperature or higher in the state wherein the material to be demagnetized is covered with a magnetic soft material. For example, the material 1 to be demagnetized (magnetized SmCo5 magnet), which is heated up to the Curie point (724 deg.C) or higher, is put in a magnetic soft material cover 2 of permalloy and the like, and a non-magnetic material cover 3 of a quartz tube and the like, together with the inert gas 4 such as argon gas and the like. The covers 2 and 3 are sealed, and then the material to be demagnetized is demagnetized by heating. Consequently, as the external magnetic field such as earth magnetism and the like is prevented by the magnetic shield of the magnetic soft material cover 2, a completely demagnetized state can be obtained without having remagnetization.

Abstract: PURPOSE:To obtain a vertical synchronizing signal similar to a horizontal synchronizing signal even being lacked in it, by converting the counted value of a counter into a data of an arbitrary bit number with a decoder, and picking up each bit of data as a timing signal in parallel. CONSTITUTION:A video signal applied to an input terminal 1 is applied to a separation circuit 2, where the signal is separated into horizontal and vertical synchronizing signals.
