Title: Semiconductor device
Inventor: YAO TSUTOMU
IPC: H01L29/41
Filed: 1980-10-03
Abstract: PURPOSE:To obtain a GTO thyristor with the uniform operation of an operation region by forming an annular gate electrode plate partly in an opposed manner with a gate electrode and contacting it with a semiconductor substrate by the pressure from an external cathode electrode via an insulator. CONSTITUTION:An annular cathode electrode plate 101, a disc-shaped cathode electrode plate 102, a gate electrode plate 110 and a cathode electrode 6 of a GTO substrate 1 are contacted under pressure with each other. The plate 110 is bonded to an insulating ceramic ring 111, and is pressure contacted with the surface of the GTO substrae by the external pressure via the ring 111. A gate lead 112 is connnected to the plate 110. Since the thickness and the width of the plate 110 are sufficiently large and the resistance of the plate is low, the voltage drop of the direction along the gate electrode plate can be remarkably reduced, thereby equalizing the turn-OFF operation and a preferable turn-OFF characteristics can be obtained.

Title: Method of controlling temperature in hot-water space heater
Inventor: YANAGIDA SHINICHIRO
IPC: F24D3/00
Filed: 1993-06-08
Abstract: PURPOSE:To prolong the service life of the devices of a hot-water space heater and save electric charges. CONSTITUTION:When a hot-water space heater is operated so that a hot water temperature is maintained at a level (for example, Ps+ or -5 deg.C) close to a predetermined set temperature Ps, a differential on a plus side is set to a higher level (for example, +10 deg.C) for a given period of time DELTAT (for example, ten minutes) after the ignition of a burner. Accordingly, the number of times of an ON/OFF cycle during the operation of the hot-water space heater is reduced, whereby the life of the devices of the hot-water space heater can be prolonged even in the case of a small load, and electric charges for an electric heater for igniting the burner are economized.

Title: Surface mounted type package
Inventor: KOMIYAMA Takeshi
IPC: H05K3/30
Filed: 1988-06-03
Abstract: PURPOSE:To prevent short-circuit or formation of solder balls between leads, by shaping the part of a package opposed to a printed board into a shape of pyramid or semicircular cylinder. CONSTITUTION:The part of a molded body 11 opposed to a printed board 13 has a shape of pyramid, and the center of the opposed part projects towards the printed board 13. Accordingly, the distance between the printed board 13 and the molded body 11 becomes larger from the center of the molded body to the sides thereof where leads 12 are provided. According to such construction, if any molten solder enters a gap between the molded body 11 and the printed board 13 while taking the form of a film, it will be guided to the larger part of the gap and allowed to escape easily from the sides where the leads 12 are provided, by the surface tension that the molten solder itself has. In this manner, it is possible to prevent short-circuit between the leads 12 caused by residual solder and to eliminate the problem that solder balls are formed between the leads 12.

Abstract: PURPOSE:To improve overall treating efficiency of a digestion tank by detecting the amt. of digestion gas generated from each digestion chamber divided to plural numbers of chamber individually, and increasing the amt. of sludge to be digested to the digestion chamber generating small amt. of digestion gas. CONSTITUTION:Raw sludge 3 is charged to a digestion chamber 2 at one end and the sludge 4 to be treated in each digestion chamber 2 overflows successively from the digestion chamber 2 at one end toward the digestion chamber 2 at another end. Digested sludge 5 and eliminated liquid 6 are drawn out of the digestion chamber 2 at another end, and the digested sludge 5 is returned to each digestion chamber 2 through a returning pump 7.

Title: Lock mechanism
Inventor: NOBUCHI ATSUNOBU
IPC: G06K13/06
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To make a lock member hard to pull out and prevent a lock mechanism from breaking by automatically disengaging the lock part, when a large force operates on the lock mechanism by giving a specific angle to a surface which is applied with a drawing-out force in a surface orthogonal to a surface with a free entry angle at the claw part of the lock part. SOLUTION: The lock part 3, equipped with the claw part having the specific angle for a free entry, has the claw part 30 slid or rotated and inserted into a specific hole 11 of a connection part to lock the connection part. Here, the surface, applied with the drawing-out force, in the surface orthogonal to the surface with the free entry angle at the claw part 30 of the lock part 3, is structurally given the specific angle θ. Therefore, when a large force is applied, for example, in the direction as shown by the arrow, a tilt part having the angle θ abuts against the inside of the claw catch part of a main body device, and this large force is applied in the direction, wherein the claw part 30 is caught inside the hole, thereby operating so that the claw 30 easily comes out of the claw catch part of the main body device.

Abstract: PURPOSE:To facilitate the removal of a jammed paper, etc., by providing the image forming device with a transfer material carrier brake means, which is released by interlocking with the abutting of the means on a transfer material carrier when the transfer material carrier abuts on an image carrier. CONSTITUTION:When a jammed transfer material is removed from the surface of a transfer drum 1, a release lever 3 is operated in a direction shown by an arrow A so as to separate the transfer drum 1 from a photosensitive drum 2. In an abutting condition, the engagement shaft 9 of the brake means engages with a main body front side plate 13, therefore a roller 7 is away from the front flange 1a of the drum 1; the engagement shaft 9 separates from the main body front side plate 13 by the rocking of a drum supporting from plate 5; consequently, the roller 7 is pressed against the front flange 1a by the reaction of an abutting spring 10, and rotation caused by the eccentricity of the rotational center of the drum 1 is prevented. Thus, the removal of the jammed transfer material on the drum 1 is facilitated. On the other hand, since a release arm 14 pushes a link shaft 17 down, a rock arm 20 rocks via a link 16, and a rotating gear 22 and a drum gear 1b mesh together; and the jammed transfer material can be removed by turning the drum 1 through manual turn of a knob shaft.

Abstract: PURPOSE:To decrease fish tails and overlaps and to improve the yield of an ingot by combining a casting mold having the bottom end part notched from the lower part toward the inside and a molding board having a slope in contact with the notched surface of the casting mold and casting the ingot having the notched bottom. CONSTITUTION:A casting mold 5 having a wide lower part and an open upper part is made into a casting mold having two notched bottom ends wherein the bottom ends 5' in both short sides thereof are notched from the lower part toward the inside to form an inclination theta. Such casting mold is combined with a specially shaped molding board 7 wherein the parts facing to both end sides of the casting mold are formed to sloped parts 7' equal to the inclination theta of the mold 5. If a casting mold 6 having one notched end and a molding board 8 having a special shape on one side are combined, the yield of an ingot decreases slightly but the set of the mold 6 and the board 8 is made simpler and since the same ingot is made castable by providing only one kind of the board 8 in stock at all times, the management is easy.
