Title: Current-voltage characteristic of photoelectronic device, method of controlling its oscillation
Inventor: YASUOKA MASAZUMI
IPC: B01J19/12
Filed: 1998-09-09
Abstract: PROBLEM TO BE SOLVED: To provide a method of raising the linearity of the current-voltage characteristics of a photoelectronic device by controlling the wavelength of light. SOLUTION: Photoelectronic device is irradiated by the light of a wavelength shorter (an energy higher than a prescribed energy) than a prescribed wavelength. whereby the current-voltage characteristics of the device are raised. The prescribed wavelength is set on the basis of an energy gap extending over from a valence band to an upper conduction band existing at an energy level higher than that of a lower conduction band. Here, when the curves 20 and 30 of the current-voltage characteristics are compared with each other, the linearity of the current-voltage characteristics at the time of a light source wavelength (λ)=674 nm (the curve 30) is more excellent than that of the current- voltage characteristics at the time of a light source wavelength (λ)=827 nm (the curve 20). That is, by changing the light source wavelength from the 827 nm into the 674 nm, a voltage index (α) is increased from 0.68 to 0.87. As a result, the linearity of the current-voltage characteristics is enhanced.

Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and method for recognizing electronic components in an electronic component mounting apparatus capable of accurate recognition for correcting misalignment of electronic components. SOLUTION: An electronic component recognition apparatus illuminates using a light source 23 an electronic component P held by a nozzle 11 attached to a transfer head, and performs an image recognition of the component P by imaging the component P with imaging means.

Filed: 1989-09-29
Abstract: PURPOSE:To improve cooling efficiency by disposing a head cooling passage and a block cooling passage in parallel, and setting the amount of supplying a cooling medium to the head cooling passage to 70% or more of the total. CONSTITUTION:A head cooling passage 11 and a block cooling passage 14 are independently formed on a cylinder head 10 and a cylinder block 13, respectively. An inlet pipe 16 includes a pair of divided flow portions 16a, 16b extended towards supply ports 11a, 14a. In this arrangement, cooling water supplied from an inlet pipe 16 to passages 11, 14 is passed through the interiors of the cylinder head 10 and the cylinder block 13 to absorb heat of each portion, thereby cooling the respective portions. As the ratio of the sectional areas of the divided flow portions 16a, 16b is set to 7:3, the cylinder head 10 which has the largest heating value is cooled by a large amount of cooling water, which is about 70% of the total. Accordingly, the head and the block can be cooled by the optimum amount of cooling water which are not subjected to mutual thermal effect.
