Abstract: PURPOSE:To securely recognize an object superposed at random by providing a means for specifying an object work and a means for estimating a following state from a present state so as to generate new runlength data. CONSTITUTION:A titled device has the means for specifying the object work which should be recognized from the runlength data and a means for generating the new runlength data from the remaining runlength data obtained by removing the runlength data of the object work when the specified object work is independent and executing the process of retrieving another independent object work and removing the runlength data of the retrieved object work when the object work is broken up. Two means are stored in a central processor 9 as recognition process programs. This recognizing work is repeated until the object works run short or until the recognition of the object works becomes impossible. Thus, the object works can be successively recognized.

At the same time, air is jetted from the interior of the container 32 toward the supply port by an inside air supply device (including a nozzle 42) so that the abrasives 46 are sent out stably from the supply port by the air flow. Then, an amount of abrasives to be supplied is adjusted by a supply amount adjusting device (rotary valve) 34 provided in the supply port. Thus, a great amount of abrasives 46 can be continuously supplied together with the air flow.

Title: Temperature compensation type amplifier
Inventor: ARAFUNE YASUNARI
IPC: H03F1/30
Filed: 1985-01-14
Abstract: PURPOSE:To eliminate the drift of voltage gain due to temperature changes by securing a positive change to the temperature for the inter-terminal voltage of the load resistances of cascaded transistors TR. CONSTITUTION:The input video signals, etc. are supplied to the base of a TRQ1 via a capacitor 1 and then amplified by TRs Q1 and Q2 to appear at the collector of the TRQ2. These amplified signals are extracted via an emitter follower of a TRQ3. While the base voltage of the TRQ3 is equal to the base voltage of a TRQ4, i.e., the reference voltage Vr since TRs Q1-Q3 are fed back in terms of DC via an error amplifier 5 and an integration circuit. At the same time, diodes D1-Dn have the characteristics a forward voltage frop VF having a negative temperature coefficient of about 1.7mV/degree. Therefore the inter- terminal voltage of a load resistance RL increases in response to the rise of the ambient temperature. The rise of this inter-terminal voltage is regarded as an increase of the collector current ICQ2 ICQ1 of cascaded TRQ1 and Q2. Thus the circuit gain is compensated to the drift of temperatures.
