Title: Height inspection device
Inventor: SUDO YOSHINORI
IPC: G01C3/06
Filed: 1989-04-18
Abstract: PURPOSE:To accurately inspect the height of a sample by excluding an area where the height of a sample can not be detected from an input image of the sample, comparing the remaining input image with reference data, and processing the undetectable part as a shadow part. CONSTITUTION:When there is image data on a component, an inspection window 33 which includes the whole component area 31 and also includes part of the shadow area 32 is set by teaching. Then, when inspection is performed, the peripheral area of the area 32 is excluded from the inspection area of the component as an unused area 35 which is not used as data. Then the height and position of the component are compared with package data and component data which are inputted previously to inspect whether the regular component is correctly arranged or not by another program. Thus, even if there is the component in the inspection area, its data is not used directly as inspection data. Therefore, the height of the component can accurately be inspected and the inspection performance can be improved.

Title: Chiller
Inventor: SUGAWARA AKIRA
IPC: F25B1/00
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption at the time of starting operation by altering the starting frequency being outputted from an inverter to a compressor at the time of starting operation through a controller depending on the refrigeration load. SOLUTION: At the time of starting operation of a chiller 10, power consumption increases as the starting frequency being outputted from an inverter 12 to a compressor 11 increases as compared with normal operation mode. While taking account of the season and the daytime or nighttime when the chiller 10 is started, a controller 19 selects a start mode such that the rising rate of the chiller 10 does not cause increase of power consumption. Since refrigeration load is high in summer season and a significant refrigerating capacity is required for the chiller 10, the controller 19 selects a starting capacity such that the compressor 11 is operated at low speed to increase the rising rate of the chiller 10 thus reducing power consumption.

Abstract: PURPOSE:To easily obtain an optical head able to separate and remove ghost light by making a first face of a beam splitter on which a beam is made incident parallel with its second face from which transmitted light emits and making the beam incident on the first face at a prescribed angle. CONSTITUTION:An incident beam 11 is made incident at an incidence angle theta which is not perpendicular on the face normal of an incidence face 19, refracted at a refraction angle (r), becomes a beam 12, passes through a half mirror face 13 and after that, goes out of a prism as a beam 15. Since the face 19 is parallel with an outgoing face 14, the beams 11 and 15 are parallel but dislocated by a distance l. On the other hand, a beam containing information reflected by the medium face traces the same optical path as the beam 15 in the opposite direction, is reflected by the face 13, becomes a beam 17, goes out and its direction is the direction of 90 deg.+2theta with the beam 11 as a reference. A ghost light 18 generated by the beam 12 being reflected by the face 14 and further, reflected by the face 13 is refracted at the refracted at the refraction angle (r) in the prism, goes out at the angle of theta in the direction opposite to the beam 17 and goes out through an outgoing face 16 in the direction at 90 deg. to the beam 11. Consequently, the beams 17 and 18 advance in the different directions at the open angle of 2theta.
