Title: Agc system for optical transmission
Inventor: TAKASE MASAHIKO
IPC: H04B10/564
Filed: 1983-09-30
Abstract: PURPOSE:To attain stable AGC operation without any pilot signal by superimposing a signal of a frequency higher than a transmission signal frequency on the transmission signal to modulate a laser diode and controlling the gain of a photodetector or a reception amplifier in response to the amplitude of a modulation signal. CONSTITUTION:The high frequency signal 12 having higher frequency than the transmission signal 11 is superimposed on the signal 11 at a superimposing circuit 13, a semiconductor laser diode 14 is modulated by the signal superimposed on the high frequency signal and the signal is converted into an optical signal, which is transmitted via an optical fiber 1. The photodetector 2 converts in a photoelectric manner the optical signal at a reception side, and after the electric signal is amplified at a preamplifier 5, the superimposed high frequency signal is extracted by a BPF7. A bias voltage 4 of the detector 2 is controlled by a signal obtained by rectifying (6) the extracted high frequency signal to control the gain of the amplifier 5. Since the amplitude of the superimposed high frequency signal is increased in comparison with that of the pilot signal, stable AGC operation immune to the effect of noise is performed.

Title: Picture forming device
Inventor: OKANO TAKESHI
IPC: G03D5/00
Filed: 1982-10-13
Abstract: PURPOSE:To prevent incidence of uneven development caused by bubbles entering into a developing section, by installing a temporary reservoir of developer to the developer inlet of a device which makes picture formation of one frame of a long film. CONSTITUTION:A long film 5 is fed from an exposure section 2 along the feeding direction F to a developing means 3 which intersects the direction F and a developer is supplied to a space between a protruded wall surface 10 and the film 5 by capillary action, and thus, only one frame of the film 5 id developed. By providing a cover 13 above the developer inlet 6 of the developing means 3, a developer reservoir 15 is formed by the right and left walls 9a and 9b of the ascending slope 9 of a picture forming unit 1, the developer hitting section 13a and developer accumulating section 13b of the cover 13. The developer is once stored in the reservoir 15 and bubbles 16 in the developer are removed by naturally introducing them to an upper space 6. Then the developer develops the film 5 and flows down along a descending slope 11 and is recovered from a recovering port 12. Therefore, uneven development due to bubbles contained in the developer is prevented and oozing out of the developer to the frames other than the one to be developed is also prevented.

IPC: G06F11/34
Filed: 1989-07-14
Abstract: PURPOSE:To easily record the distribution of the arising time of multiple events arising at short intervals by providing a measuring value conversion device generating the storage address of a value operating an addition command by setting the measuring value of time when the event arises as input. CONSTITUTION:The measuring value conversion device 23 generates an address signal from the measuring value transmitted from an event arising time measurement device 22 and the addition command which means the increase of a value stored in a place designated in the address based on a measuring value conversion system which a monitor event designation device 21 designates. Since the measuring value is converted and recorded by the measuring value conversion device 23, the quantity of recording medium can be reduced, and the need of a sorting job after the termination of measurement is eliminated. Thus, the distribution of the arising time of the multiple events which arise at the short intervals can be easily be recorded.

Title: Mis type field effect transistor
Inventor: SAITO TORU
IPC: H01L21/283
Filed: 1989-07-14
Abstract: PURPOSE:To obtain an interface excellent in property so as to improve a MISFET in characteristics by a method wherein a gate insulating film is formed on a GaAs substrate by alternately laminating two types or more of different II-V compound semiconductor thin films. CONSTITUTION:A superlattice 7 composed of two types or more of II-V compound semiconductors 7a and 7b is laminated on a GaAs substrate 1 to serve as a gate insulating film. For instance, the thin films 7a of ZnSe and 7b of ZnS are alternately laminated to form a ZnSe/ZnS distorted superlattice 7, and when the superlattice 7 is used as a gate insulating film, GaAs, ZnSe, and ZnS crystal are different from each other in lattice constant, but as the layers forming the gate insulating film are extremely small in thickness, the lattice is distorted, dislocation caused by lattice disconformity is not induced, and uncoupled hands are very few at an interface of GaAs/insulating film. By this setup, an insulating film very small in interface state density can be formed, so that a metal/insulator/semiconductor field effect transistor MISFET of high performance can be obtained.

Title: Method for controlling cutting with continuous casting installation
Inventor: SUZUKI MASAKAZU
IPC: B22D11/126
Filed: 1984-08-31
Abstract: PURPOSE:To improve yield by feeding back not only the actual cutting length of the own strand but also the actual cutting length of the other strands and controlling collectively the determination of the set cutting length of all the strands. CONSTITUTION:The cutting length for each billet determined by a computer 2 for control are set in control devices 5, 6 for cutting of the respective strands and the actual cutting of the billet is executed by cutting machines 7, 8. Length measuring devices 9, 10 take the actual value of the casting length therein and also take the actual cutting length of the cut billets therein. The length measuring devices feedback such values to the computer 2. The actual cutting lengths of not only the own strand but also the other strands are thus taken into the above-mentioned devices and the target intended cutting length of the other strands is also handled as a reference product length and therefore the optimization of combination is made better than in a cutting method in which the strands are independent. The yield is thus improved.

Filed: 1982-10-14
Abstract: PURPOSE:To prevent gnawing between a drive piece and engaging projection by turning a reel hub with a slope of the drive piece at reproduction without producing uneven turning and engaging the engaging projection of the reel hub to a part risen steeply from the circumference of the reel shaft in winding the tape in high speed at fast-forwarding. CONSTITUTION:The upper part of one side face of the drive piece 2 of the reel shaft 1 is formed into a steep surface 21 risen steeply from the outer circumference of the reel shaft 1, and the lower section is formed with a slope surface 6 where the radius is increased gradually in radial direction from the outer circumference of the reel shaft 1. At the reproduction where the reel shaft 1 is turned while being shifted upward, the engaging projection 4 of the reel hub is engaged with the steep surface 6 and turned, on the other hand, when the reel shaft 1 is depressed at the fast-forwarding, the engaging projection 4 of the reel hub is engaged with the steep surface 21 and turned at the fast-forwarding. Thus, even if the turning of the reel hub 2 is locked instantly at the end of tape at fast-forwarding, since the steep surface 21 of the drive piece 2 is engaged with the engaging projection 4, no gnawing takes place.

Filed: 1982-10-15
Abstract: PURPOSE:To prevent fogging due to examination light by providing a sequence circuit which generates a strobe flash signal one field (frame) scanning period after the reception of the 1st transfer gate signal after a release detection signal is generated. CONSTITUTION:When a shutter release button 32 is pressed, a release detection signal is outputted 56 and inputted to the sequence circuit 54. Consequently, the examination light is cut off 58 and an examination lamp 24 is turned off completely a specific delay time later. The circuit 54 receives the output 52 of the transfer gate signal generated at every interval of a field (frame) and outputs a timing signal for the light emission of a strobe lamp 30 longer than one field scanning period after the 1st gate signal arrives after the detection signal is generated. Consequently, a strobe flash in a field wherein the examination light is present is avoided to prevent fogging due to the examination light.
