Title: Solid state image pickup device
Inventor: SUZUKI TOSHIKI
IPC: H04N5/335
Filed: 1981-07-20
Abstract: PURPOSE:To eliminate the moire and improve the picture quality, by storing a solid state pickup element within a package substrate, fixing a crystal plate onto the substrate as a cap and making the incident light separated by the crystal plate enter the contiguous picture element on the image pickup element. CONSTITUTION:A crystal plate 8 is fixed onto a ceramic substrate as a cap. The thickness of the plate 8 is set properly, and the incident light 7 has complex refraction through the plate 8 and is separated into incident lights 7a and 7b. These lights irradiate a contiguous picture element 6 of a solid state image pickup element 2. In other words, the thickness of the plate 8 is set so that the space between the lights 7a and 7b is set equal to the pitch space of the picture element. Thus the light entering a certain picture element also enters the contiguous picture element, and the signal frequency component fP is reduced. As a result, the folded component fS-fP is larger than the cutoff frequency fC. Thus no moire is observed ona monitor screen.

Inventor: ATAKA TATSUAKI
IPC: H01M10/39
Filed: 1983-06-22
Abstract: PURPOSE:To obtain a secondary battery which can be made small and thin, the capacity of which can be increased and in which no generation of dendrite and gas is caused by using an oxidized body of a specified polynuclear metallic complex as a positive active material and a reduced body of said complex as a negative active material.

Title: Central type suction cleaner
Inventor: FUJIWARA TOSHIAKI
IPC: A47L9/28
Filed: 1989-05-01
Abstract: PURPOSE:To adjust suction force easily by providing both a phase-controlling part wherein a voltage signal from a voltage-transduction part is transduced to an angle of conduction and a fan motor is driven, and a hose-inserting part whereby a frequency-transducing part in a hose assembly is connected to the voltage-transducing part in a cleaner main body. CONSTITUTION:A phase-controlling part 23 is so formed that the output voltage of a voltage-transducing part 21 is transduced to an angle of conduction by an IC 24 specialized for phase control; i.e., to a small angle at low voltage, and to a large angle at high voltage. At the cleaning for a curtain or the like, an input-setting part is set to a high resistance. In this way, a low frequency signal from a frequency- transducing part 2 is transmitted to a voltage-transducing part 21 in a cleaner main body 40, from lead wires in a hose assembly 10 through a hose-inserting part 50. The low voltage corresponding to the lower frequency signal is outputted from the voltage-transducing part 21, and since a fan motor 30 is driven at the small angle of the conduction by the phase-controlling part 23, the suction force of the title cleaner becomes weak. On the other hand, at the cleaning for a carpet or the like, the fan motor 30 is driven at the large angle of conduction, and hence its suction force can be made strong.

The secure bonding force enough for practicability is obtd. by coating, adding and depositing the inorg. porous material to the stock particles under heating. This filter medium has the large surface area of the filter medium itself and in addition, the pores of the porous material added and deposited to the front surface thereof are not closed and therefore, excellent effect as filter medium is exhibited.

Title: Prevention of resin running during joint construction by resin injection
Inventor: NAKAMURA MASANAO
IPC: E04C5/18
Filed: 1989-05-02
Abstract: PURPOSE:To shorten the time of cleaning as well as improve appearance by preventing the dripping of resin by a method in which the lower part of resin- injecting joint of threaded knot reinforcing bars is wound with a resinous tape with projections or attached with a container of small capacity. CONSTITUTION:The lower part of the resin-injecting joint 2 of a threaded knot reinforcing bar 1 is wound with a resinous tape 4 with projections 41 or detachably attached with a small capacity container 5 of water-proof water or resin. A resin 3 is injected from the joint 2, and when the resin 3 begins to flow out from both ends of the joint 2, the completion of injection is confirmed. The resin 3 which flows out is received by the projections 41 of the tape 4 or by the container 5 to form a resin trap. The dripping of the resin can thus be prevented, the number of cleaning processes can be reduced, and the time of cleaning can also be shortened. The finished appearance can also be greatly improved.

Title: Manufacture of sintered ore excellent in reducibility
Inventor: KATO TOMONORI
IPC: C22B1/16
Filed: 1987-05-12
Abstract: PURPOSE:To efficiently manufacture a sintered ore having superior load softening characteristic and excellent in reducibility, by blending coarse-grained auxiliary material for MgO source having a specific grain size with basic starting material, such as iron-ore fines, and a slagging agent, coke fines, etc. CONSTITUTION:An auxiliary material for MgO source for improving the flowability of blast-furnace slag and also improving load softening characteristic in a blast furnace, such as serpentine, and a slagging agent, such as limestone fines, are blended with a basic starting material such as iron-ore fines and Fe-containing dust. Then, prescribed percentage of coke fines is added to the sintering raw material obtained by the above procedure, which is subjected to sintering. In the method for manufacturing the above-mentioned sintered ore, the grain size of the above auxiliary material for MgO source is regulated so that grains of 1-10mm grain size comprise >=50wt.%. By coarsing the grains of the above auxiliary material, MgO is made difficult to react with Fe2O3 at the time of sintering, and the formation of magnetite is inhibited. As a result, the quantity of FeO in the sintered ore is reduced and the reducibility of the sintered ore can be remarkably improved.
