Title: Semiconductor laser and manufacture thereof
Inventor: YAMAGOSHI SHIGENOBU
IPC: H01S5/00
Filed: 1986-03-10
Abstract: PURPOSE:To improve the light emitting efficiency of a semiconductor laser by forming a primary quantum well structure in a triangular shape, extremely narrowing the width of the vertex of the triangle to form a quantum well structure also in a lateral direction to sharpen a gain curve and to reduce a threshold current. CONSTITUTION:A primary quantum well structure 2 is formed on an N-type indium phosphide substrate 1. Then, when a moirelike etching mask 3 is formed by a 2-luminous flux interference exposure method and wet etched, a specific surface is formed so that theta becomes 70 deg.32'. When it is so etched that an indium phosphide layer 22 of the uppermost layer for forming the structure 2 becomes the vertex of a triangular shape, the mean width of an indium gallium arsenide phosphide layer 21 of the lower layer becomes 100Angstrom  or shorter to satisfy quantum well conditions, thereby performing a secondary quantum well structure 4. The mask 3 is removed by dissolving, and a contact layer of a P-type indium phosphide layer 5 and a P<+> type indium gallium arsenide phosphide is formed.

Title: Biaxial tilting specimen holder
Inventor: SUZUKI SEIICHI
IPC: H01J37/20
Filed: 1994-03-23
Abstract: PURPOSE:To satisfy eucentric conditions by making a specimen installation stand move in X-direction when it moves in Y-axis tilting axial direction. CONSTITUTION:The tip of the Y-axis tilting axis 3 is made to be like a needle to prevent a specimen holding unit 2 from shifting in the tilting axial direction and the Y-axis tilting axis 4 is made movable in Y-direction to transmit the driving force for specimen transportation in X-direction. When a pin 15 is pushed by a lever 14 by rotating a Y-axis tilting rod 13, the Y-axis tilting axis inclines the unit 2 on both tilting axes 3, 4. Regarding X-direction movement of the specimen, when an X transportation driving lever 5 is move right and left on a fulcrum 6, the tilting axis 4 joined to the tip of the lever moves in Y-axial direction. Consequently, an X transportation driving lever 7 joined to the tilting axis 4 rotates on a fulcrum 8 and slides the pin 9 to the center and a specimen installing stand 10 in X-direction. Consequently, at the time of image observation, the center of a visible field is brought into harmony with the Y-axis tilting axis by operating the lever 5, so that a specimen 11 moves on the tilting plane.

Title: Electronically controlled fuel injection device
Inventor: MEGURO TAIICHI
IPC: F02D41/12
Filed: 1982-03-31
Abstract: PURPOSE:To prevent hunting by a method wherein the amount of correction is reduced upon idle inertia running in which a clutch is being left in connection in the fuel injection amount control device for the internal-combustion engine. CONSTITUTION:In a step 23, it is decided whether a throttle switch 1 is put ON or not. When the throttle switch 1 is put ON or an accelerating device is closed, it is decided that the engine is idling and the decision of a car speed condition is effected in the step 27. When the car is in a condition of inertia running, a process to switch the amount of correction is effected in the step 30. When the car is in the condition of idle inertia running in which the clutch is being left connected, the amount of correction is reduced in a degree that the idling rotation of the engine is not increasing extremely. Thus, the hunting may be prevented.

Title: Transmission for vehicle
Inventor: TAKAHASHI TAKASHI
IPC: B60K17/08
Filed: 1983-03-30
Abstract: PURPOSE:To make a mechanism into simplification and lightweightness as well as to aim at improvements in a rate of fuel consumption, by coupling a planetary gear transmission mechanism and a planetary gear shaft different in a transmission ratio each, together in common in series, while making one of internal gears brakable selectively by means of liquid pressure. CONSTITUTION:One of braking devices 11a-11c of a multistep transmission mechanism A is selectively operated, while one of braking devices 12a-12b of a multistep transmission mechanism B is as well operated, and when each internal gear is set in brake motion, power of an input shaft 1 is gear-shifted and transmitted to an output shaft 2 via a planetary gear transmission mechanism corresponding to the brake motion of these internal gears. When the braking device is changed over, the transmission of power in another transmission ratio takes place via another planetary gear transmission, that is to say, a 6-step transmission is performable owing to the gearshift of 3-step speed at the S side and 2-step speed at the B side. In addition, when one side of these braking devices 12a and 12b of a reverser mechanism C is operated, power of the input shaft 1 is shifted to 2-step speed and reversely transmitted to the output shaft 2. With this, improvements in lightweightness and fuel consumption can be well promoted as a compactified transmission mechanism.

IPC: G06F9/48
Filed: 1988-03-07
Abstract: PURPOSE:To prevent the concentration of processing into a specific terminal by varying the priority of tasks for processing terminal I/O requests within a previously set variable range. CONSTITUTION:When a task with a task number Ti is started by an I/O request of a terminal 3a, the task number Ti is set up in an information area correspond ing to the terminal 3a in a control table TB2.
