Patent JP-H0529084-A (JP)
Title: One-pulse starting lighting device provided with protective device of discharge lamp
Inventor: NAKAMURA MITSUHARU
IPC: H05B41/06
Filed: 1991-07-17
Abstract: PURPOSE:To provide a thermal switch to be used for both of lighting start and protective start of the last stage of a lamp life by providing two sheets of bimetals having different curved parts from each other and a resistor on one side lower end part and a stopper on the midway between the other side and itself respectively. CONSTITUTION:Bimetals on the side of a fixed contact 13 and on the side of a movable contact 14 are fixed in the shape of pine needles. When these are electrically conducted, the parts 10 and 15 are curved due to self-heating so as to curve both of the tip contacts in the same direction however, the contacts 13 and 14 are dissociated from each other because the part 15 has a longer curved part. A generated pulse at this time can light up a discharge lamp 2 by one pulse. Further, since the part 15 continuously curves at the time of the last stage of the lamp life due to heating of a resistor provided in connection with the lower end 19 of the bimetal on the side of the contact 14, the side of the contact 13 is made to stop by a stopper 21 so as to hold both contacts in an open state in order to perform a part of protection.

Title: Squelch circuit
Inventor: MATSUMOTO SATOSHI
IPC: H04B1/44
Filed: 1991-09-19
Abstract: PURPOSE:To eliminate an unpleasant sound at transmission/reception changeover by providing the squelch circuit completely cutting or decreasing noise at the transmission/reception changeover. CONSTITUTION:When a transmission/reception switching signal 9 changes from an L to an H level, a power supply is supplied to a reception system and the circuit is set to the reception state and when no input comes from an antenna 1, an audio signal 10 before squelch operation is outputted from an audio amplifier circuit 6. On the other hand, a squelch signal 12 outputted from a squelch signal detection circuit 8 is inputted to an AND gate circuit 18. Simultaneously, a one-shot circuit 17 generates a pulse 19 by a delay of the squelch signal 12 from a change point of a transmission/reception switching signal 9 from L to an H level and the pulse 19 is inputted to an AND gate 18. The two signals pass through an AND gate circuit 18, from which a squelch signal 20 without a delay is inputted to an audio gate circuit 7. Thus, the noise at transmission/ reception changeover is completely eliminated.

IPC: H04N5/57
Filed: 1988-10-28
Abstract: PURPOSE:To display a picture with excellent contrast by inputting a difference signal to a limiter and limiting the signal at preset upper and lower limits. CONSTITUTION:A mean value detection circuit 21 obtains a mean value Y'' of a luminance signal Y and inputs the result to one terminal of a subtractor 22. A subtractor 22 subtracts the mean value Y'' from the luminance signal Y and inputs the result of subtraction to a limiter 23. A level control circuit 15 obtains a signal being a difference between the luminance signal Y and its mean value Y'' and outputs a Y' signal in which the difference signal limited by the preset upper and lower limits is within a prescribed upper and lower range of the mean value Y'' of the luminance signal. Then primary color signals R', G', B' are extracted from color difference signals R-Y, B-Y based on the luminance signal Y, by a matrix circuit. Thus, the primary color signals R', G',B' are of a prescribed range of level based on the luminance signal Y' at all times and all the gradation of a liquid crystal display panel is utilized effectively. Thus, a picture with excellent contrast is displayed on the liquid crystal display panel.

Title: Paper feed device and printing device provided with it
Inventor: SUZUKI HIROSHI
IPC: B65H3/06
Filed: 1996-10-14
Abstract: PROBLEM TO BE SOLVED: To realize a construction in which paper sheets of different width are hardly sent out in a slanting state by a simple construction. SOLUTION: Ordinary business forms and envelopes are respectively set based on a reference guide 30a, and sent out by two paper feed rollers 41a, 41b. The paper feed roller 41b on the far side from the reference guide 30a is formed into a larger diameter than that of the other roller 41a. In an envelope facing sideways, the protruded side from the paper feed roller 41b is sent out without delaying against the other side regardless of resistance applied to the part, by strong feeding force and a large feeding quantity of the paper feed roller 41b. When the envelope is curved along a slope 51 for separation, the protruded part is slided on a thin plate 52b of small friction coefficient, and hence it gets over the slope 51 with little slant.  The ordinary business form is slantingly sent out from a paper feed hopper due to difference of the feed quantities of both rollers, but it is resisted and corrected by a feed mechanism 7 on the lower stream side.

Filed: 1986-11-14
Abstract: PURPOSE:To make it possible to operate a transistor at a low voltage, by providing a multiple-quantum-well structure, in which two or more well layers and barrier layers are alternately laminated between a collector layer and a base layer, and gradually changing the forbidden band width of the barrier layers in the direction of a film thickness. CONSTITUTION:On an n-GaAs substrate 1, the following layers are sequentially grown as crystals: a collector layer 2; an i-AlGaAs layer 3; a multiple- quantum-well structure (i-MQW layer) 4; an i-AlGaAs layer 5; a base layer 6; and an emitter layer 7. At this time, as the barrier of the i-MQW layer 4, a barrier, whose forbidden band width is changed in the direction of the film thickness in a graded mode, is used. Since electrons can pass without being captured in the i-MQW layer 4 even at a low electric field, a transistor can be operated at a low voltage.

Title: Locking wavy spring washer and manufacture thereof
Inventor: MORIMOTO TOSHIAKI
IPC: F16B43/00
Filed: 1995-09-12
Abstract: PROBLEM TO BE SOLVED: To provide a washer having a locking effect more effective than the conventional wavy spring washer, by providing a prescribed amount of V-shaped grooveless parts in an internal/external diametric side of a width surface, and providing a plurality of locking V-shaped grooves engraved in the rest of curved surface part. SOLUTION: A V-shaped groove is engraved in a width surface of a wavy apring washer. When it is built in a bolt and tightened, a mate member of bolt seat surface, tightened material, or the like, contacting with the V-shaped groove generates plastic deformation by axial force of the bolt, is slightly swollen in the V-shaped groove, and a coefficient of friction is increased, so as to increase a locking effect. In a part without engraving a prescribed amount of the V-shaped grooves is provided in an internal/external circumferential part, when a wavy part comes to be flat by compression force in the case of using this washer as a product, tensile force in the internal circumferential part and compression force in the external peripheral part are applied, but a crack generation by stress concentration due to a notch, is eliminated.

Title: Molding method for annular molded product
Inventor: SUZUKI SATOSHI
IPC: F16J15/3252
Filed: 1990-10-09
Abstract: PURPOSE:To prevent the occurrence of defective molding by forming a passage for connecting a first space on the inside diameter side and a second space on the outside diameter side in the protrusion, formed on a top mold, with a metallic ring in a cavity serving as a boundary therebetween and causing a fluidized material under molding to flow through the passage. CONSTITUTION:A protrusion 20 is formed on a first top mold 13 so that a metallic ring 2 is pressed between a protrusion part 19 and the aforesaid protrusion and in the direction of the width of the metallic ring 2. The protrusion 20 is formed such that a groove part for a molding material, such as rubber, is formed. A rubber flow groove 21 lies in the central part of the protrusion 20 and forms a passage by which a cavity 18 connects a first space 22 on the inside diamater side and a second space 23 on the outside diamater side the matallic ring 2 making the boundary between the two spaces. In the middle of molding of an oil seal 1, a molding material is caused to flow through a gap between the protrusion 20 and the metallic ring 2. Especially, at a protrusion 20 part being a fluid terminal spot of a rubber molding material 21, the rubber material 21 flows through the rubber flow groove formed in the protrusion 20 part, and a flow area is increased. This constitution prevents the occurrence of defective molding, such as nicks of rubber.
