Abstract: PROBLEM TO BE SOLVED: To dispense with optical adjustment for positional adjustment in the horizontal direction parallel to a substrate by respectively arranging two kinds of optical parts of a semiconductor laser and an optical waveguide to be optically coupled, confronting them with each other and arranging these optical parts within the range of a prescribed error. SOLUTION: An optical coupler 1 is constituted so that the array like semiconductor laser 200 having a light emission part arranged at a prescribed pitch is confronted with the array like optical waveguide 300 having a core 302 arranged at the prescribed pitch. The optical waveguide 300 and a bonding pad are formed on the surface of the substrate 100. The semiconductor laser 200 is positioned so as to make the position that the light emission part of a central part among the array like light emission parts coincides with a central core among the array like cores of the optical waveguide 300 a target to be bonded to the bonding pad. In such a case, the deviation from the target position of the semiconductor laser 200 is suppressed to 15μm or below.

Filed: 1998-10-07
Abstract: PROBLEM TO BE SOLVED: To facilitate tactics at the time of a battle, and at the same time, expand the role of an enemy character by providing a conversation display means which performs the display of a conversation with a comrade or an enemy character which is designated by a character designating means. SOLUTION: An attack right recognizing section 71 recognizes that a player character has an attack right. An input command selecting section 72 displays a character cursor when a conversation is selected from a command input window by moving a command cursor by the depressing of a direction key of a controller 3. A character designating section 73 designates a character by moving the character cursor by the depressing of the direction key of the controller 3. A conversation display section 74 reads the conversation data for information regarding an enemy character from a conversation data storage section 75 with the enemy character in a battle as a key, and displays the conversation data on a display 4. Thus, when an attack right is turned to a player character, a character is designated, and conversation sentences of the character are displayed.

Title: Information processor
Inventor: OKUMURA KOJI
IPC: G06F9/38
Filed: 1990-11-22
Abstract: PURPOSE:To improve the instruction processing performance of an information processor by suppressing the advance operations of subsequent instructions that are carried out by a 2nd computing element with the signal given from a detection circuit. CONSTITUTION:A 1st computing element 26 controls the storage operand lap- around operation. If an instruction enables a 2nd computing element 28 to perform the operations, an SOW control circuit 25 detects a fact that the arithmetic control is carried out by the element 26. Then a detection circuit 30 sends a detection signal to a 2nd computing element control circuit 29. Meanwhile a 2nd computing element SOW control circuit 31 detects a fact that a storage operand lap-around operation was carried out by the element 28 and informs the circuit 30 of this fact. Thus it is assured that the element 26 never performs an operation in advance of the element 28.

As the element is controlled with a modulator 10 with the application of a voltage of a capacitor voltage divider 1 thereto, emission of the LED 3 is turned to a light modulated by a voltage signal. The light modulated generates a Faraday effect in a coil 4 by a magnetic field with a current flowing to the coil 4 through a Faraday effect element 6 placed between a polarizer 5 and an analyzer 7 to cause a modulation of light. Light emitted from the analyzer 7 is received with a photo diode PD8 to be converted into electricity which is passed through a low pass filter 9.
