Title: Shell screening machine and screening method for nuts
Inventor: SHIBAYAMA AKIRA
IPC: B07C5/342
Filed: 1988-02-03
Abstract: PURPOSE:To execute efficient screening by providing a light projecting means which projects light on a mixture and a detecting means which selectively detects only the near IR rays among the reflected light rays from the mixture. CONSTITUTION:Materials to be screened in which the seeds and shells of nuts are mixed are released from a belt conveyor and fall along the prescribed track. A sensor 6 keeps receiving the near IR rays and outputs an electric signal by converting the light to said signal. The sensor 6 receives the near IR rays reflected from the body of the nut if the body of the nut passes an observation section X. The level of the IR rays reflected from the body is the same as the level of the IR rays irradiated from the background. The level of the near IR rays in the wavelength received by the sensor 6 increases and the voltage level of the voltage signal outputted from the sensor 6 temporarily exceeds a selection standard when the shell passes the observation section X. The signal is supplied to a monostable multivibrator 14 during this time.

Title: Thickness detection apparatus
Inventor: MORITA SHIGERU
IPC: G01B7/06
Filed: 1985-02-12
Abstract: PURPOSE:To obtain the title detection apparatus having a simple structure and easy to handle, by discriminating whether a dielectric member has the same thickness as a reference one from the equilibrium and non-equilibrium state of a Wheatstone bridge circuit. CONSTITUTION:When an unknown number of magnetic sheets are supplied to the capacitor 7 between electrodes for performing discrimination, the capacities of the capacitors 6, 7 between electrodes become equal if one sheet and a Wheatstone bridge circuits is under an equilibrium state and, because no potential difference is generated getween connection points (a), (b), an AND circuit 13 generates no output even if a gate signal 14 is applied. However, if a plurality of magnetic sheets are supplied, difference is generated between the capacities of the capacitors 6, 7 between electrodes and the Wheatstone bridge looses equilibrium and potential difference is generated between the connection contacts (a), (b). Therefore, when the gate signal 14 is applied, the AND circuit 13 generates out-put and the number of the magnetic sheets supplied to the capacitor 7 between electrodes can be detected.

IPC: H01S5/00
Filed: 1992-02-12
Abstract: PURPOSE:To reduce the capacitance and the dark current and to realize high sensitivity reception by dividing and anode electrode or a cathode electrode into two regions. CONSTITUTION:A semiconductor laser diode body 1 is covered with an electrode 2 and divisional electrodes 3, 4 of divided electrodes. When it is used as a light emitting element, the electrode 3 is coupled to the electrode 4, and a current flows to the electrode 2. Thus, a laser light is outputted from both end faces of the diode 1. When it is used as a light receiving element, the electrodes 3, 4 of the side for inputting light are connected to a receiver circuit. Thus, the current proportional to the light input flows between the electrodes 3 and 2. The capacitance as the light receiving element is the capacitance between the electrodes 3 and 2. This becomes smaller than that when the electrode is divided. When it is used as a photodetector, the divisional electrodes are used thereby to reduce its capacitance and dark current.
