Patent JP-S60163508-A (JP)
Title: Optical reception circuit
Inventor: NAITOU SEIGO
IPC: H04B10/50
Filed: 1984-02-03
Abstract: PURPOSE:To attain stable amplification with less effect against the change in temperature and power supply voltage by using the circuit of the same constitution as an amplifier circuit for the next stage and selecting the combination of resistors connected between them. CONSTITUTION:A circuit 2 which is the same constitution as a circuit (trans- impedance type amplifier) 1 is connected via a resistor R4. A base current of a transistor (TR) Q3 is a difference between a current I1 flowing to the resistor R4 and a current I2 flowing to a resistor R6, an output voltage V3 of the circuit 2 cancels the temperature characteristic with a ratio of R6/R4 set to 7.24 in a typical case when the ratio of collector currents IC3 and IC1 is taken as 5, and the R6/R4 is coincident with the voltage gain of the 2nd stage. The circuit 2 is a circuit where the DC temperature characteristic is changed by the gain and the temperature characteristic is neglected with the gain of 7 times. The IC1, IC3 have a tendency to be increased with the power supply voltage increased, the ratio has less voltage dependancy and is made stable against the power supply voltage.

Title: Radiographing device
Inventor: KARASAWA HARUO
IPC: G03B42/02
Filed: 1988-01-29
Abstract: PURPOSE:To prevent invalidation of data and the interruption of handshake due to erroneous operation of a power switch by preliminarily setting the degree of importance of each processing and controlling switching between continuation and immediate power-off of a processing in accordance with the degree of importance of the processing operation. CONSTITUTION:Radiographic information transmitted through an object 12 is stored and recorded in a stimulable phosphor 13, and this information is read and is converted to digital image data by a means 17, and this data is read and stored by a means 25 and is processed by a means 26 and is subjected to communication processing by a means 19. The degree of importance of each processing is preliminarily set. When the degree of importance of the processing operation performed at the time of detecting the turning-off operation of the power switch is high, the power source is turned off after this processing operation is terminated; and when it is low, the power source is immediately turned off. A control means 21 is provided to control switching between power-off after the processing operation and immediate power-off. Thus, data is prevented from being invalidated by power-off, and handshake is prevented from being interrupted during data transmission to and reception from an external device by power-off.

Title: Information processor
Inventor: MORITA NOBUTERU
IPC: G06F11/28
Filed: 1985-02-05
Abstract: PURPOSE:To obtain an information processor which is capable of highly efficient virtual console control by adding a serial interface to a microprocessor together with a decoding circuit for input data. CONSTITUTION:When serial data is supplied to a serial interface 10, an interruption is informed to a microprogram control part 12. At the same time, the reception data is sent to a decoder 11 via a parallel output line 15. The decoder 11 decodes the reception data and drives a display signal line 16 when coincidence is obtained between the reception data and the 1st code decided previously. The part 12 checks an interruption source and then checks the display signal on the line 16 when the interruption source is equal to the interface 10. While the virtual processing is carried out in case the interruption source is identical to said 1st code. When the reception data is equal to the prescribed 2nd code, the decoder 11 drives a display signal line 17. The part 12 checks the line 17 and drives a signal line 18 in the case of the 2nd code. Then the actuation of the decoder 11 is inhibited for the next reception data.

The upper end of the stopper 23 is positioned at a place higher than the upper surface of the conveyor belt 10, furthermore, a tilted surface 24b is formed at the forward end of a projection 24c. This allows the forward end of the form to be lowered down along the above said tilted surface, even if the form is transferred while it is stuck on the lower surface of the conveyor belt 10 because of static electricity. And after a clapper has been deflected, the form is positioned in a void between the clapper 25 and the bottom section 24 allowing the form to be positively housed in the bottom plate 21 of the chassis, that is, the stacker.

Title: Multi-port memory
Inventor: YAMAMOTO HIROAKI
IPC: G11C11/41
Filed: 1994-02-17
Abstract: PURPOSE:To perform read-out at high speed and to reduce power consumption increasing noise margin by making a reference voltage supplying circuit the same load constitution as a read-out bit line and pulling up a reference bit line in a pull up circuit. CONSTITUTION:A reference bit line 12 used for reading out a multi-port memory cell 2 is made the same load constitution as a read-out bit line 4, and a pull up circuit 18 is connected to the bit line 12. Thereby, when one side value of a binary number is written in the cell 12, a potential on the bit line 4 is not varied, a potential on the bit line 12 is decreased gradually as variation is suppressed by the circuit 18. On the other hand, when the other value of the binary number is written in the cell 2, a potential on the bit line 4 is dropped more quickly than a potential on the bit line 12. Therefore, contents of the cell 2 can be discriminated from a difference of variation of a potential. By using this constitution, deviation of timing and a difference of a potential between the bit line 4 and the bit line 12 are almost eliminated, and read-out can be performed at high speed.

Abstract: PURPOSE:To easily load and unload a film cassette by providing an internal cylinder which is movable in a thrust direction in order to engage the cylinder with the film winding shaft of a camera, and transmitting its rotating force to an external cylinder for taking up a film through a gear mechanism. CONSTITUTION:When an opening/closing cover 9 is closed after a cassette body 1 is loaded, a lock lever 51 rotates clockwise, and a slide plate 39 is unlocked to slide upward by the restoring force of an energizing spring 44. Then, a press-up pin 45 moves up by the restoring force to abut on the internal cylinder 21 at the film take-up part 4 of the cassette body 1. Consequently, the internal cylinder 21 moves up and the engagement pawl part 24 of the internal cylinder 21 engages with the pawl part 47 of the film winding shaft 46. Therefore, the rotation of the film winding shaft 46 is transmitted to the internal cylinder 21 through pawl parts 47 and 24 and the rotation of the internal cylinder 21 is transmitted to the external cylinder 22 through the gear mechanism 27 consisting of an external gear 25 and an internal gear 26 to take up a film 5.

Title: Tape loading device
Inventor: ZAITSU OSAMU
IPC: G11B15/665
Filed: 1985-02-05
Abstract: PURPOSE:To reduce a device in size and to lighten its weight by causing a guide drum to move at the 1st position facing a cassette reel over a tape stretched before a tape cassette, the 2nd position in the opening of the tape cassette and the 3rd position nearer to the cassette reel than the position in the opening. CONSTITUTION:Before tape loading, a guide drum 60 is located at the 1st position C1. When the tape cassette is contained in a cassette holder to load said holder on a device main body, the guide drum 60 is moved to the 2nd position C2 to complete a tape cassette loading action, thereby obtaining the prescribed tape path. Where the cassette holder is loaded on the device main body without containing the tape cassette in the cassette holder, the guide drum jumps to the 3rd position C3 from the 1st position C2, skipping the 2nd position C2. Thus the tape loading device with the guide drum 60 as a center is practically absorbed in a tape cassette occupying space except such a case that recording and reproducing a tape is executed by loading the tape cassette, and therefore the tape cassette size of a final target can be obtained.
