IPC: H01J17/49
Filed: 1979-08-10
Abstract: PURPOSE:To dispose display elements in a high density and reduce the number of lead terminals by laminating with interposed insulation plates a plurality of display elements, each of which is made of an insulation plate and has a pair of discharge electrodes, one on one side of the insulation plate and the other on the other side thereof, and by making the top faces of said elements as light emitting portions. CONSTITUTION:Each display element 8 is obtained by forming an anode 2 on one side of an insulation plate and a cathode on the other side of the insulation plate, which is shaped into a rectangle in its cross-section. A plurality of elements 8 are laminated with insulation plates 10 interposed between each two adjacent elements 8.

Title: Sea-level reflection suppression circuit
Inventor: WATANABE TETSUJI
IPC: G01S7/34
Filed: 1991-05-08
Abstract: PURPOSE:To enable a clutter due to a sea-level reflection wave to be suppressed over a wide dynamic range. CONSTITUTION:Two variable gain intermediate frequency amplifiers 1 and 2 which are connected in series by placing tuning circuits 3 and 4 are subjected to gain control by a first gain control voltage S4 and a second gain control voltage S5 according to two systems of gain-control circuits, respectively, and then a characteristic at a lapse of time of degree of amplification by two variable gain intermediate frequency amplifiers 1 and 2 becomes a straight line by these two gain-controlling voltages and at the same time a dynamic range is also expanded. A buffer circuit 7 receives a trigger pulse S3, a first gain- controlling voltage S4 is generated by a monostable multivibrator 8a, a CR differential circuit 9a, and an amplifier 10a, and then a second gain-controlling voltage S5 which is delayed from the first gain-controlling voltage S4 is generated by a monostable multivibrator 8b, a CR differential circuit 9b, and an amplifier 10b. A sea-level reflection suppression variable resistor 11 allows an output pulse height of the monostable multivibrators 8a and 8b to be variable and time versus degree-of-amplitude characteristic by two variable gain intermediate frequency amplifiers 1 and 2 to be shifted in parallel.

Title: Manual card reader
Inventor: SATOU SUSUMU
IPC: G06K7/01
Filed: 1980-07-26
Abstract: PURPOSE:To read information on a card securely by applying a braking roller with displacing force and braking force force simultaneously by the braking roller  and an elastic member press-contacted with it. CONSTITUTION:A braking roller 36 is provided corresponding accurately to the guide groove 17 of a card and as a card 11 is inserted, the inserting force of the card permits the roller and a support part 37 to rotate on a shaft 45 counterclockwise against the operating force of a leaf spring 39. On the other hand, although the roller is rotated by the frictional force by the braking roller 36 and card 11, the braking roller 36 brakes the card 11 because of an increase in the braking force from the leaf spring 39. Namely, the braking roller 36 serves as an insertion load on the card 11 to suppress the extent of the insertion.

Title: Formation of pattern
Inventor: TODA KAZUO
IPC: G03F7/039
Filed: 1981-06-30
Abstract: PURPOSE:To increase the solubility of a cross-linking agent in a positive type photoresist by using novolak sulfonyl azide as the agent. CONSTITUTION:A positive type photoresist contg. novolak sulfonyl azide represented by the structural formula as a cross-linking agent is used in a photolithographic method. Since novolak sulfonyl azide is compatible with a resist such as polymethyl methacrylate or polybutene sulfur, it can be contained in the resist at high concn. and can enhance the accuracy of a pattern and the sensitivity of the resist. When novolak sulfonyl azide is added to a positive type photoresist with sensitivity to electron beams as a cross-linking agent, the dry etching resistance of the resist is also enhanced.

Title: Extruded aluminum section having bright specular surface and production thereof
Inventor: KATOU SENOO
IPC: C25F3/20
Filed: 1988-04-26
Abstract: PURPOSE:To produce a superior product without plating by successively subjecting an extruded section of an Al alloy having a specified compsn. to physical polishing and electrochemical polishing. CONSTITUTION:An Al alloy contg., by weight, >=0.02% Si, >=0.02% Cu, >=0.2% Mg and <=0.1% Fe is extruded. The resulting extruded section is successively subjected to physical polishing and electrochemical polishing to form a bright specular surface having <=0.3mum surface roughness and >=80% reflectance. In the Al alloy, Si is required to provide brightness but an excess of Si present alone deteriorates brightness. Si coexisting with Mg forms Mg2Si and can prevent the deterioration of brightness. Cu increases the strength of the alloy and is required to provide brightness but an excess of Cu tinges the alloy with yellow. Mg is required to provide strength. The amt. of Fe is made as small as possible so as to avoid adverse effects such as the lowering of reflectance and coloring.

IPC: H03L7/08
Filed: 1986-05-06
Abstract: PURPOSE:To prevent a phase-locked oscillator due to saturation from being unlocked by adjusting a variable resistor connected to a loop filter to cancel an input offset voltage only when the output of the loop filter is saturated. CONSTITUTION:An output voltage of the loop filter 3 is monitored by using a loop filter output voltage monitor circuit and whether or not an output voltage of the loop filter 3 is saturated positively or negatively is confirmed by using a voltage saturation detection circuit 5. When the voltage is saturated, a variable resistor drive circuit 6 is used, a variable resistor 7 inserted to the input side of a comparison power supply of an operational amplifier at the 1st stage of the loop filter 3 is adjusted to change the voltage of a reference power supply input thereby cancelling the offset voltage by the change in the voltage of the reference power supply input. Thus, the loop filter 3 is operated at the non-saturation region to lock the phase-locked oscillator.

Title: Fault detecting circuit
Inventor: ITOU YUKIO
IPC: G06F11/30
Filed: 1980-07-29
Abstract: PURPOSE:To detect a fault of data buffer control in its early stage, by providing with a circuit which detects the vacant state of a data buffer. CONSTITUTION:When a write indication signal A is supplied, the contents of a bus are written in one word of a data buffer DB indicated by a counter CT1, which goes up by one. A read indication signal B permits a counter CT2 to goes up by one. At the point of time when the data buffer DB should be empty while the said operation is repeated, the contents of the write and read indication signals A and B supplied to the counters CT1 and CT2 are considered to coincide with each other. For this purpose, a processing end indication signal C is sent out and when the output of a comparing circuit CMP is not a ''1'', and AND circuit AND outputs a ''1'', thereby reporting a fault. Consequently, the counters CT1 and CT2 are capable of detecting the fault of a part controlling the issuing of the signals A and B without fail.

Title: Forming device for thin layer of developer
Inventor: EGAMI HIDEMI
IPC: G03G15/09
Filed: 1983-06-14
Abstract: PURPOSE:To circulate sufficiently magnetic powder in a container by setting magnetic flux density on the developer holding surface of a conveyance part smaller than that on the surface of a magnetic power constraining magnetic pole. CONSTITUTION:A conveyance pole 21 is provided on the upstream side of the magnetic particle constraining magnetic pole 20. This magnetic pole 20 sets the magnetic flux density on the surface of the developer holding member 12 to 300-700 gauss. This magnetic flux density is such a value as to constrain magnetic particles in the container 13, and put the particles in sufficient motion. The conveyance pole 21 sets the magnetic flux density to 300-500 gauss smaller than the magnetic particle constraining magnetic pole 20. When the density is within said range, the magnetic pole 21 conveys magnetic particles from a seal magnetic pole part 22 to the magnetic pole 20 together with a nonmagnetic developer, so the presence of conveying force is limited to near a developer holding member 12. In such a way, the magentic particles are circulated in the container sufficiently.
