IPC: H03K17/04
Filed: 1985-08-05
Abstract: PURPOSE:To increase the peak value of current flowing between the emitter and base of a main transistor (TR) and to quicken the time required for turning off the main TR by connecting an inductive element between respective collectors of the main TR and the pre-TR. CONSTITUTION:When a contact 3a of a switch 3 is turned to the 1st fixed contact 3b, the pre-TR 4 is turned on and then the main TR 5 is turned on. When the contact 3a is turned to the 2nd fixed contact 3c, current I1 outputted from a reverse bias power supply 2 and flowing from the collector to the base of the pre-TR 4 through a current feedback diode 6, the 2nd inductive element 9 and a diode 7 and current I2 passing from the emitter to the base of the main TR 5 and flowing from the emitter to the base of the pre-TR 4 through the 1st inductive element 8 are obtained. Since the reverse bias current I2 for turning off the main TR5 can be made to flow more than the absence of the inductive element 9, the time required for turning off the main TR 5 is quickened.

IPC: B65G47/52
Filed: 1990-06-29
Abstract: PURPOSE:To enable sorted articles to be easily taken out from a receiving dish on which the sorted articles have been put in and which has been sorted and discharged by a sorting conveyor, by means of a transfer control device for controlling the transfer of receiving dishes on the basis of the detection of the presence of sorted articles on the dish at the terminal part of a taking-out conveyor device. CONSTITUTION:At the terminal part 4b of a taking-out conveyor device 4, the presence of vegetables and fruits 100 on a receiving dish 1 is detected by a photoelectric sensor, and only empty dishes 1 are discharged from the terminal part 4b onto an empty- receiving-dish transfer device 6. When a receiving dish 1 on which vegetables and fruits 100 have been put in and which is being transferred by the conveyor device 4 reaches the terminal part 4b without being taken up by an encasing worker, the presence of articles is detected by the photoelectric sensor, and a stopper device 5 is operated by the operation signal from a control circuit based on the signal of this sensor, so that the transfer of the dish 1 carrying vegetables and fruits 100 can be prevented. When the vegetables and fruits 100 are taken up from the dish 1 being stopped, the operation of the stopper device 5 is released on the basis of the detection of the photelectric sensor, and only the empty dish 1 is discharged onto the empty- receiving-dish transfer device 6.

Title: Semiconductor storage device
Inventor: SAITO YOSHIKAZU
IPC: G11C11/413
Filed: 1986-07-23
Abstract: PURPOSE:To remove the possibility of destruction of stored information in the title semiconductor memory storage without a sharp increase in power consumption by a method wherein the resistance load of the memory cell, to be formed on the circumferential part of a memory mat, is selectively brought into the state of low resistance. CONSTITUTION:On an S-RAM 100, the load resistance only to be used for a memory cell 121, among a number of memory cells 121 and 121' to be arranged on a memory mat part 120, is selectively brought into the state of low resistance. Consequently, a relatively large memory holding current is permitted to flow on the memory cell 121'. As a result, the effect of a current inflited on the holding state of memory information is relatively small even when a current escapes a little from the drain of the MOS transistor which constitutes the memory cell 121', and said leakage of current can be neglected substantially. On the other hand, a load resistance of a sufficiently high resistance value is used on the greater part of the memory cells 121 other than the memory cells 121' so that the memory holding current will be brought to the minimum, and the increase in the entire power consumption becomes small. Through the above-mentioned procedures, the destruction of the stored information in S-RAM can be prevented.

Title: Laser recording monitor
Inventor: MIYAUCHI AKIO
IPC: B41M5/26
Filed: 1979-12-27
Abstract: PURPOSE: To enable to monitor flaws of recording medium and recording state with a simple construction, by detecting the laser light transmitted through a recording medium and comparing the detection signal with data signal.  
     CONSTITUTION: The information signal output from a magnetic tape device 9 is processed at a signal processing circuit 8 to output the data signal S1. The signal S1 drives a photomodulator 7 to modulate the light from the laser light source 6. The rotating mirror 10 deflects the modulation light, which is irradiated on the recording medium 2 to melt the recording layer. The light transmitted through the recording medium 2 with melting is converted into the signal S2 at a photoelectric converter 11, and if S1, S2 are not in coincidence, the comparator 12 outputs the signal S3, from which defective recording and the presence or absence of flaws of recording medium can be detected. Further, at nonrecording, a photomodulator 7 deflects the laser light toward L1 to lower the light quantity of straight line light L0, allowing to heat the recording medium to the extent that it is not recorded.
