Patent JP-H01318271-A (JP)
Title: High output semiconductor laser
Inventor: HAYASHI NOBUHIKO
IPC: H01S5/00
Filed: 1988-06-17
Abstract: PURPOSE:To make a threshold value current for oscillation small and simplify its manufacturing process by a method wherein the reflectivity and film thickness of a photo-guide layer are set so as to have a light confinement coefficient and it is covered with a material functioning as a clad layer instead of an active layer or a third clad layer in the vicinity of the incidence end surface of laser beams. CONSTITUTION:A first clad layer 2, a photo-guide layer 3 and a second clad layer 4 are laminated in this order from top of an n-GaAs substrate 1, and the reflectivity and film thickness of the photo-guide layer 3 are set so as to have a light confinement coefficient of the same degree as in a case where there is no photo-guide layers in an excitation area. In the excitation area, an active layer 5 is laminated on the second clad layer 4, and a third clad layer 6 and a cap layer 7 are laminated in this order on the active layer 5. Since degradation of light confinement to an active layer is suppressed by adjusting the reflectivity and film thickness of a photo-guide layer in this way, a threshold value current for oscillation can be made small, and high-output laser beams can be oscillated. Also, its manufacturing process can be simplified.

Title: Chattering rejection circuit
Inventor: AOKI HIROSHI
IPC: H03K5/1254
Filed: 1979-11-21
Abstract: PURPOSE:To ensure to reject the chattering pulse, by controlling the input level of a C<->MOS inverter when the input signal level is inverted and holding said input level to one of the two levels when the input and output levels are corresponded. CONSTITUTION:When a terminal P is inverted to ''1'' with chattering, FETs T2, T3 are respectively on and off. Thus, the charge of a capacitor C is discharged via a resistor R. The time constant by the capacitor C and the resistor R can be set so that the potential at the terminal (a) reaches the threshold level V of an inverter V1 after the time (t) with this discharge. Accordingly, even if the pulse having narrower width than that of the time (t) by chattering is incoming, the voltage at the terminal (a) does not reach voltage V and the output of the inverter V1 is held at ''0''.

Title: Preparation of reforming catalyst for hydrocarbons
Inventor: ASAKI AKIYOSHI
IPC: B01J23/75
Filed: 1998-06-01
Abstract: PROBLEM TO BE SOLVED: To provide the method for preparing the hydrocarbon reforming catalyst which enables the improvement of the reforming ratio of hydrocarbons by increasing the ratio of the content of the catalyst components per the surface area. SOLUTION: Primary raw materials of alumina and magnesia are mixed with nickel oxide in a wet process, then after drying and pulverizing to obtain the mixture and, adding a binder to the mixture and granulating the mixture together with an organic nucleus. Through- holes 3 are formed from the surface to the nucleus in the radial direction of the granulated molded material and the nucleus is removed by cracking. After calcining, the molded material is fired to form a hollow carrier having an internal space 2. The carrier thus obtained is immersed into a solution containing nickel nitrate and at least one compound of rare earth elements to impregnate these compounds into it, and then dried. The thus treated carrier is again fired to obtain the reforming catalyst.  As the carrier containing catalyst components and having reforming activity is further impregnated with the catalyst components, the ratio of the content of the catalyst components per the total surface area can be increased, and thereby the reforming effect is improved. The shortening of the impregnation time, the improvement of the productivity, the increasing of the surface area and the lightening of the catalyst are achieved by providing the through-holes 3 which are communicated to the internal space 2.
