A CCD microscope includes: two polarized light illumination systems for irradiating polarized lights having vibrating directions in perpendicular to each other selectively to an object to be observed, and an analyser disposed on an optical path from the object to a CCD device for picking-up an image of the object, the analyser having a vibrating direction in parallel with the vibrating direction of the polarized light from one polarized light illumination system, and in perpendicular to the vibrating direction of the polarized light from the other polarized light illumination system. The surface state of the object is picked-up by a polarized light of one polarized light illumination system that is kept unchanged for the polarized state upon reflection on the surface, while the inner state of the object is picked-up by a polarized light of the other polarized light illumination system that is changed for the polarized state.

A construction machine includes an engine, a hydraulic pump driven by drive force of the engine, a generator motor, and a dipstick tube. The generator motor is disposed between the engine and the hydraulic pump. The generator motor has a rotary shaft connected to an input shaft of the hydraulic pump and to an output shaft of the engine and an oil pan disposed in a lower part of a holding space formed inside a housing. The dipstick tube has a connector provided at a location that communicates with the oil pan of the generator motor, and a dipstick opening disposed above the generator motor, for checking a level of oil in the oil pan.

When the flying height of a magnetic head slider lowers, there arises the problem that the magnetic head slider assumes a forwardly falling attitude and a front edge portion of a leading end of the magnetic head slider comes into contact with a magnetic disk surface, causing damage to the disk surface. To address the problem, one aspect of the invention is directed to a magnetic head slider which includes an air bearing surface, a leading end and a trailing end. Three flying pads are formed on the air bearing surface and a step bearing surface is formed around the first and second flying pads near the leading end and a negative pressure groove for producing a negative pressure is formed in such a manner that the leading side is surrounded by the step bearing surface. The third flying pad is formed near the trailing end and is provided with a magnetic head. A step bearing is formed on the leading side of the third flying pad. Further, the magnetic head slider is formed with an aperture in a front edge portion of the leading end.

This invention uses a 4-line color CCD sensor including four line sensors Y, R, G, and B. In a low-speed color read mode, outputs from these sensors are processed by A/D converters and subsequent processing units provided in one-to-one correspondence with the sensors. In a high-speed monochromatic read mode, an output from the Y sensor is divisionally processed by using A/D converters and subsequent processing units provided in one-to-one correspondence not only with the Y sensor but also with the other R, G, and B sensors. This provides an image reading apparatus usable in both the high-speed monochromatic mode and the low-speed color mode and capable of achieving high speed, high accuracy, and low cost.

A motor (17a, 17b) opens and closes a shutter turnably mounted so as to open and close a discharge port relevant to a hopper, and generates a torque against a load in a gravity direction of materials dropped from a material supply mechanism to the hopper. A shutter control portion (19a, 19b, . . . 19h) sets a hold current applied to the motor from the start of loading relevant to the shutter caused by the materials to be dropped to a predetermined period, to a first hold current value for applying to the shutter a torque sufficient to bear the shock during charge of the materials. In addition, the control portion sets a hold current applied to the motor from an elapse of the predetermined period after reception of the materials by the hopper to the start of discharging the materials from a discharge port of the hopper, to a second hold current value that is smaller than the first hold current value, the second hold current value applying to the shutter a torque against a force released downwardly under a load in the gravity direction of the materials.

A plurality of semiconductor integrated circuit devices are mounted on a film carrier. First electrical connecting sections and first electrical wiring sections for electrically connecting the first electrical connecting sections to the semiconductor integrated circuit devices are provided on the film carrier. Second and third electrical connecting sections and second electrical wiring sections are provided on a film-like probe for electrical characteristic test. The second electrical connecting sections are provided in position corresponding to the first electrical connecting sections of the film carrier. The third electrical connecting sections are used to supply electrical signals to the exterior or derive an electrical signal to the exterior and check the electrical signal. The second electrical wiring sections connects the second and third electrical connecting sections to each other. The film-like probe and the film carrier are superposed on each other so as to set the second electrical connecting sections of the filmlike probe into contact with the first electrical connecting sections of the film carrier.
摘要:
A hot water circulating system capable of decreasing energy loss, increasing the amount of hot water to be circulated per unit time and reducing time required for each circulating cycle. The system includes a valve opened at the start of emptying of water out of a water boiler to supply water from an open tank to the water boiler. The water boiler is divided into a heated section and a hot water receiving section arranged above and communicated with the heated section.
