SOLUTION: The resonance level of light positive holes in a p-type GaSb quantum well layer 104 is just above the lower end of the conduction band of an n-type InAs emitter layer 106, so that the effective heights of AlSb barrier layers 103, 105 can be made minimum, under the condition that a resonance tunnel exists. Thereby the maximum width of resonance level can be obtained under the condition that a resonance tunnel exists. The increase in a valley current caused by that the resonance level being just above the lower end of the conduction band is not recognized. Thereby the peak current density can be improved, without decreasing the ratio of a peak current to a valley current, in the resonace tunnel diode structure having a constant barrier width.

Abstract: PURPOSE:To make one lamp usable for two purposes by sticking a reflective film onto the inner surface of a glass tube while leaving a main opening and a sub-opening, both of which have fixed angles within the glass tube, and also adhering a fluorescent film onto the reflective film and the sub-opening. CONSTITUTION:While rare gas and mercury are filled in a glass tube 1 with electrodes 2 at its both ends, a reflective film 5 is pasted onto the inner surface of the glass tube 1, with a main opening 3 having a fixed angle theta1 and a sub- opening 4 having an angle theta2 left, and a fluorescent film 6 is stuck onto the reflective film 5 and the sub-opening 4, thereby forming a reflextype fluorescent lamp for an optical equipment. Accordingly, light from the main opening 3 is used for illuminating a draft in such an optical equipment as a copying machine, while light from the sub-opening 4 can be utilized for other purposes such as nonelectrification of a photosensitive drum, with decline of light output from the main opening 3 being prevented. Thus, it is possible to make the lamp smaller and less electric power consuming.

Title: Defect detecting apparatus
Inventor: KANDA TOMOYUKI
IPC: H04N7/18
Filed: 1990-08-23
Abstract: PURPOSE:To achieve a high speed for inspecting operation by providing frame memories for storing input images for a plurality of screens, and reading the input image which has been already stored out of the other memory when the image is inputted and stored into one frame memory. CONSTITUTION:One of the image signals which are digitized in an A?D converter part 4 is temporarily stored in a first frame memory 5A which is selected with a first switching circuit 6A. The other signal is inputted into an inspecting- region determing part 12. In parallel with this operation, the stored image signal is read out of a second frame memory 5B which is selected with a second switching circuit 6B, and the image signal is outputted into a window circuit 13. Thus, the input and the defect detection in the field-of-view region for the inspection can be continuously performed. The inspecting region of the input image can be determined by using an input screen within the period of one frame in parallel with the storing of the input image. Since the window processing is performed when the stored input image is read out, the high speed of the alter processing can be readily achieved.
