Title: Light emitting element driving circuit
Inventor: HAYASHI SHIGERO
IPC: H01L33/00
Filed: 1988-02-22
Abstract: PURPOSE:To keep an output constant and to reduce the danger of a thermorunaway in a light source for optical communication and so on by overshooting to a driving current with a constitution to delay the output monitor signal of a driving device for a fixed time and to execute a negative-feedback. CONSTITUTION:A current corresponding to the difference between a non- inversion input and an inversion input is supplied to an LED 10, and a driving device 11 to output a monitor signal corresponding to the supplied current and a delay device 12 to delay the monitor signal for a fixed time Td and to feed it back to an inversion input terminal 14 are provided. Then, when a rectangular wave type signal is inputted to an input terminal 15, the output of the device 11 rises sharply as indicated in a broken line (a). After that, when the delay time Td passes, since the monitor signal is given to the terminal 14 and is negative-fed back, an output current (the optical output of the LED) is reduced as a waveform (b) and is stable at a fixed value.

Title: Trapping device
Inventor: UCHIYAMA MASAYUKI
IPC: B01D35/06
Filed: 1979-04-02
Abstract: PURPOSE: To hold arrested foriegn matters exactly without missing them by shielding electrostatically foreign matters arrested around the arresting electrode of a trapping device after being arrested.  
     CONSTITUTION: AC voltage is applied across the container 1 and the electrode conductor 3 to cause electrid field to produce inside the container 1, whereby electrostatic force is exerted to the foreign matter 7 in an insulating gas, e.g., SF6 gas, so as to move it with a complicated movement. In this case, because the weak electric field 8 is formed near the arresting electrode 9, the foreign matter 7 which reached the weak electric field 8 is stayed as such. After arresting the foreign matter 7, the left and right coupling pieces 17 and 18 are melted away from the outside of the container 1 by using a burner, etc., and thereby the right and left electrostatic shielding plates 12 and 13 are partly pushed out to the outside of the lower space 9a by the springs 16 and 15. Thus, the foreign matter 7 staying in the weak electric field 8 is shielded against the conductor 3 by the plates 12 and 13 and therefore no escape of the foreign matter 7 from the weak electric field 8 takes place even if abnormal voltage is applied across the conductor 3 and the container 1.

Title: Memory access system of multiprocessor system
Inventor: OOHIRA EIJI
IPC: G06F13/00
Filed: 1979-04-04
Abstract: PURPOSE: To make it possible to make programs of all processors equal to one another, by using a bus exclusive right signal or a bus exclusive permission signal to designate the address space of a memory.  
     CONSTITUTION: Now, if processor 2 is in the memory access enable state, register 6 accesses the memory space in the address of an area corresponding to processor 2 according to the address signal from processor 2 because the flag signal of address register 6 becomes 0. If processor 3 is in the memory access enable state, the flag signal to register 6 becomes 1, and consequently, register 6 accesses the memory space in the address of an area corresponding to processor 3 according to the address signal from processor 3. For the flag signal of register 6, a bus exclusive right signal or a bus exclusive permission signal itself is used in case of two processors, and a signal obtained by encoding these signals is used in case of three or more porcessors.

Title: Pressure measuring apparatus
Inventor: MUTOO KATSUTOSHI
IPC: G01L9/00
Filed: 1978-04-04
Abstract: PURPOSE: To provide a pressure measuring apparatus of high accuracy with reduced effect of errors by electromagnetic induction noise by photoelectrically detecting the change of pressure by the use of optical guides such as optical fibers.  
     CONSTITUTION: When the pressure F to be measured is transmitted via receiving member 15a to a movable optical fiber 13, the optical fiber 13 is displaced in correspondence to said pressure by a spring body 15b constituting movable device 15. When the optical coupling loss between a stationary optical fiber 12 and movable optical fiber 13 displaces according to the displacement quantity of the optical fiber 13, the quantity of light arriving at a photo detector 11 attenuates according to the coupling loss. As a result, it turns out that the quantity of light of the photo detector 11 changes in correspondence to the displacement quantity of the movable optical fiber 13. Hence, photoelectric conversion of the quantity of light propagated through the optical fibers 12 and 13 with the photo detector 11 causes the converted electric signal to correspond to the pressure F and therefore, the pressure measuring apparatus of high accuracy by which the magnitude of the pressure is known from this electric signal may be obtained.

CONSTITUTION:A collecting chamber 10 is equipped with an exhaust pipe 11 for the condensed solvent and provided with a bypass hole 12 which puts the chamber 10 in communication with a wind path 4 at upstream of a blower 5. When the circulating wind fed from this blower 5 passes a condenser 6, the liquefied condensed solvent drips and passes an auxiliary condenser 9, and thus the solvent is stored in the collecting chamber 10. When the circulating wind passes the condenser 6, mist form solvent is generated, which will be collected by the mentioned auxiliary condenser 9. That is, when the bypass hole 12 is opened, the collecting chamber 10 gets neg. pressure more than the circulating wind path at downstream of the blower 5 by the suction pressure at upstream of the blower 5. At this time, the mist form solvent is condensed and stored in the collecting chamber 10.

Filed: 1983-03-11
Abstract: PURPOSE:To enable to observe faithfully the far field pattern of an infrared ray laser light by eliminating the background infrared radiation from the surroundings to a screen for observing the far field pattern. CONSTITUTION:Coolant such as liquid nitrogen 32 is contained in the inner package 21 of a vacuum heat insulating container 30 incorporating the screen 25 and two infrared filters 26 and 27, thus cooling the incorporated screen 25 and each of the infrared filters 26 and 27 to a low temperature. The screen 25 is irradiated with the infrared laser light 33 from one infrared ray transmitting window 28 through the infrared filter 26 in this state, resulting in the image pickup of the irradiated pattern through the other infrared ray transmitting window 29 and the infrared filter 27. Such a manner enables to inhibit the infrared radiation from the screen 25 and the infrared filters 26 and 27 themselves because those members are cooled. Since the background infrared radiation from outside is eliminated by said container 30, etc., the far field pattern of the infrared laser light can be observed faithfully.
