Title: Semiconductor integrated circuit
Inventor: YOSHIDA SHIRO
IPC: H01L23/522
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To prevent unnecessary high frequency current flowing in a power line from flowing to an outer part by installing a ground by making it face a power wiring (conduction wire) and arranging a decoupling capacitor in the pad part of power wiring. SOLUTION: A ground 3 is installed by making it face power wiring (conduction wire) 2 in a semiconductor integrated circuit being air wiring where a ground layer does not exist. The ground 3 is installed in the semiconductor integrated circuit and a micro strip line is formed with the conduction wire 2. A decoupling capacitor 1 is arranged in a pad part 5 connected with the lead frame of the conduction wire 2 for making noise suppression effect to be maximum. Unnecessary frequency current flowing in a power line is bypassed to the ground 3 through a via hole without making it flow to the outer part of the semiconductor integrated circuit by arranging the decoupling capacitor 1. Electromagnetic radiation noise from a printed board mounting the semiconductor integrated circuit can be suppressed.

Title: Drum unit
Inventor: YAMAGAMI SHINJI
IPC: G11B5/52
Filed: 1992-02-04
Abstract: PURPOSE:To provide a drum unit of a small-sized VTR having excellent recording and regeneration characteristics. CONSTITUTION:A shaft-bearing 40 is fitted into a lower drum 8 with a loose tight fit or a clearance fit. After fitted, an outer ring 12a of the shaft bearing 40 is fixed with the lower drum by using a bonding agent injection jig 50 to a bonding agent injection hole 13a which is opened on the slant. The bonding agent injection hole 13a is arranged to be opened on the slant so that the bonding agent injection hole 13a may not strike against the outer periphery of the lower drum 8. Therefore, it is possible to reduce the height of the lower drum 8 and maintain the shape accuracy of the lower drum, such as out of roundness of its outer periphery so that excellent recording and regeneration may be available.

Title: Radio alarm unit
Inventor: KUMAGAI YOSHIZO
IPC: H04B7/15
Filed: 1986-01-29
Abstract: PURPOSE:To prevent effectively a stray child by using a radio alarm unit generating an alarm tone when a distance between a slave set and a master set is a prescribed value or over. CONSTITUTION:The slave set 1 given to a little child or a schoolboy sends a pass word code. The master set 2 discriminates whether or not the device code of a sending slave set and the pass word are coincident and sends another pass word when they are coincident. A slave set 5 receiving an alarm discriminates whether or not the device code and the pass word of the master set in the signal from the master set 2 are coincident and operates an alarm tone generator. The alarm tone generator generates an alarm tone so as to confirm the location of the transmission slave device 1 at the reception alarm slave set while the master set 2 is used as a repeater when the distance between the transmission slave set 1 and the master set 2 exceeds a setting value.

Title: Hygrometer
Inventor: YABUSAKI SHIYUNICHI
IPC: G01N27/22
Filed: 1978-02-20
Abstract: PURPOSE: To measure humidity by the output of an operational amplifier by letting the outputs of two sets of resonance circuits be differential inputs to the operational amplifier.  
     CONSTITUTION: The outputs of first, second resonance circuits 3, 4 are rectified respectively by rectifying circuit 9, 10 and are applied as differential inputs to an operational amplifier 11 and therefore the outputs corresponding to the differences in the outputs of  the respective resonance circuits 3, 4 appear in the output side of the operational amplifier 11. Since the capacitor 6 constituting the resonance circuit 3  is so constituted that its capacity value changes with humidity, the output of the first resonance circuit 3 changes considerably with humidity. Hence, the output differences of the first, second resonance circuit 3,4 change with humidity and this turns out that a meter 13 indicates the value corresponding to humidity.

Title: One touch joint
Inventor: NAGAKI YOSHISHIGE
IPC: E04B7/04
Filed: 1996-02-05
Abstract: PROBLEM TO BE SOLVED: To make it possible to speedily, surely and easily fix a roof panel to a roof beam of a room unit by only taking advantage of the dead weight of the roof panel. SOLUTION: When a male type joint piece 2 is inserted from an opening on one end side of a female type joint piece 4, the front end sections of rising pieces 312 are moved to an opening on the other end side while bending them along the tapered interior wall surface of a hollow section 412. With the constitution, since claw sections 313 make acute angles with the rising pieces 312, the claw sections can be easily inserted because they move with a forward inclination while rubbing against the interior wall surface of the hollow section 412. Then, since a guide pin section is not rotated by a lock mechanism in case of insertion, the movement of the rising pieces 312 is not interrupted with the corner of the body 333.  In such a joint state, since a pair of claws 313 make acute angles with the rising pieces 312 to interlock the female type joint piece 4, it is very hard to pull the male type joint piece 2 out of the female type joint piece 4, and they are surely connected to each other.

Abstract: PURPOSE:To recover the sensible heat of blast furnace slag effectively as a heat source to be blown into a blast furnace by dry-granulating the molten slag discharged from the blast furnace in an adjacent hea recovery tower, heating the air fed from its lower part into hot wind and passing the same through a filter material thereby removing harmful gases. CONSTITUTION:The molten slag 11 of a blast furnace carried to the upper part of a heat recovery tower 1 is accumulated once in a molten slag well 3, and a cover is put thereon, thence compressed air 8 is fed and a stopper 7 is opened to drop the molten slag to the lower part of the tower 1 through a nozzle 9. At this time, the slag 11 is dry-granulated 13 by jet air nozzles 10 provided around the nozzle 9, and while the granular slag is dropped downward, it is solidified and piled to obtain blast furnace slag particles. At the same time, the blast furnace blast 12 fed from the lower part of the tower 1 is heated, whereby the recovery of waste heat is accomplished. The hot wind heated to high temp. goes through an upper communicating pipe 16 into a hot wind purifying tower 2, where it is removed of harmful gases with a filter material 15, after which it is directed to a hot stove 21.
