Title: Control system of voltage type inverter
Inventor: TOMITA HIROO
IPC: H02P27/06
Filed: 1984-11-26
Abstract: PURPOSE:To limit a motor loss to the minimum required limit by accurately grasping the vibrating state of a motor current by a current state discriminator, and altering the output voltage/frequency characteristics of an inverter only when the vibrating state is judged. CONSTITUTION:A current state discriminator 7 processes a detected current as prescribed to decided whether a motor current is in vibrating state or not, and stores the state in a memory 8 when in the vibrating state. The output of the memory 8 is led to a function generator 3, thereby altering a voltage command from the generator 3. Thus, when judging that the motor current is in the vibrating state, the output voltage/frequency ratio of an inverter is weakened to alter to the direction of excitation.

IPC: B01D57/02
Filed: 1992-08-03
Abstract: PURPOSE:To take the samples separately, continuously and quickly without skill by forming a crack part at the halfway of a capillary column constituting a migrating electrode, covering the crack part with covering material, and forming an electrode connecting part.

Title: Sunshine sensor
Inventor: MAKI ETSUKO
IPC: G01J1/02
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To reduce the influence of skylight illumination causing noise, and enable accurate detection of direct sunlight, by judging direct sunlight on the basis of each detection signal of a light detecting part, when light shielding material does not shield the direct sunlight, or shields it. SOLUTION: A light receiving part 2 is arranged facing upward, at the center of a base 1, which is covered with a semi-spherical transparent cover 3. A semi-circular light shielding part 4 is fixed to the base 1, and 180 deg. reciprocal pivotal movement along the outer or inner surface of the cover 3 around a horizontal shaft 6 is made possible by a driving part 5. For example, the horizontal shaft 6 is arranged in the east and west direction, and the light shielding part 4 is made to pivot in the north and south direction. In this case, a detection signal V of the light receiving part 2, at a position where the light shielding part 4 does not shield sunlight, becomes the sum V1 of the direct sunlight and the skylight from the part except the direction of the sun. At the position where the sunlight is shielded, the detected signal becomes V2 which is an amount of only the skylight.  As a result, the level of only the direct sunlight at the position where the sunlight is shield becomes the difference between the sum V1 and the skylight amount V2 . Therefore the influence of skylight illumination causing noise is reduced, and direct sunlight can be accurately detected.

Title: Semiconductor optical integrated element and its manufacture
Inventor: KUDO KOJI
IPC: H01S5/00
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor laser with a spot size converter of of a low threshold value and high efficiency and a manufacturing method of an optically integrated element for realizing a structure thereof. SOLUTION: In a spot size conversion region B of light beam in a semiconductor laser with an active region A and the spot size conversion region B, while a thickness of an optical waveguide layer is thinned to be tapered in an optical waveguide direction, layer thickness change rate in the taper part is larger in upper and lower light confinement layers 2, 4 than in a quantum-well layer (MQW layer) 3. Since the active layer 3 having the same layer thickness as the active region A is in the spot size conversion region B, a semiconductor laser without a region causing optical loss can be realized by making a current flow to all the regions, thus reducing the threshold value current and improving efficiency.
