Title: Hot-wire air flowmeter
Inventor: FUMINO TAKAYUKI
IPC: G01F1/684
Filed: 1991-03-20
Abstract: PURPOSE:To prevent the contamination of a hot-wire and heat sensitive resistor by providing a wing in front of the entrance section of a by-pass passage. CONSTITUTION:A wing 8 composed of a plate which is parallel with the central axis of a main passage 6 and the downstream section of which is bent toward the central axis of the main passage 6 is fitted to the front section of the entrance of a by-pass passage 5 of the body 1 of this air flowmeter with four bars. Since the amount of the air flowing into the main passage 6 from the air flowing from the front of the entrance of the by-pass passage 5 increases as the flow speed of the air increases, the influence of contamination is reduced by decreasing the flow velocity of the air in the passage 5 by reducing the air flow flowing through the passage 5. In addition, the relation between the contamination and flow velocity of the air flow can be adjusted by changing the flow rate of the air flowing through the passage 5 by adjusting the bent angle of the downstream section of the wing 8.

Title: Hot water supply device
Inventor: MORI KINJI
IPC: F24H1/10
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To prevent the temperature of tapped hot water caused by a cold water sandwiching phenomenon at the time of tapping hot water again, wherein a heat exchanger having burners which are separated into a plurality of combustion portions is provided, and at the time of stopping a hot water supply, some partial burners continue their combustion for a given time and the burners stop the combustion thereafter. SOLUTION: When an operation of a hot water supply device is started, if a detected signal of a water flow rate sensor 6 judges that a water flow rate is equal to or more than an ignition water flow rate and a hot water tap is opened, water is supplied at a flow rate equal to or more than a given water flow rate and a gas burner 10 is ignited. In this condition, a combustion control is carried out by a combustion gas amount control with a gas proportional valve 14 and solenoid valves 15-17 and a combustion air control effected by a rotational speed control of a combustion fan 11. Thereafter, if it is judged that the gas burner 10 is under a partial combustion and a shower or the like which taps a small amount of hot water is used, it is judged whether the partial combustion has continued for or exceeding a given time (e.g. 30 minutes).  If this judgment is affirmative, a combustion is stopped after the partial combustion is continued for a given time (e.g. 0.5-1 second).

Title: Magnetic head and its production
Inventor: WATANABE ISAO
IPC: G11B5/23
Filed: 1982-04-07
Abstract: PURPOSE:To set accurately the gap of a touch face to a magnetic tape or the like and form this gap easily, by holding many nonmagnetic particles whose diameters are uniform between a pair of cores and joining cores. CONSTITUTION:Many glass beads 5 as nonmagnetic particles are dispersed and put on the inside face of a core 1. These glass beads 5 have a high melting point and a uniform diameter. Cores 1 and 2 are allowed to opposte to each other through glass beads 5 placed between them and are pressed to hold glass beads 5 between them. Thus, even if faces of cores 1 facing each other are warped, the gap between them coincides with the diameter of glass beads 5 and is uniform in any part. In this state, a galss 6 having a low melting point is melted and packed between faces opposing to each other. Consequently, a gap (g) between cores 1 and 2 is very accurate and is produced in a simple process.

Title: Disk device
Inventor: NITSUTA YOSHIISA
IPC: G11B17/24
Filed: 1994-03-28
Abstract: PURPOSE:To simply set the dimension and fitting position of a cushion part for absorbing impact at the time of closing a tray. CONSTITUTION:The cushion part 70 of elastic deformability is formed integrally with a main gear 23 for controlling timing of moving the tray 2. Immediately before the tray 2 is closed, an abutting part provided projectingly on the lower surface side of the tray 2 is abutted against the cushion part 70. Then, kinetic energy of the tray 2 is absorbed by elastic deformation of the cushion part 70, and a speed of the tray 2 is gradually lowered and stopped. Consequently, impact of the tray 2 can be prevented. The dimensions and disposing position of the cushion part 70 can unequivocally be decided by calculation, and since the adjustment by trial and error as in the conventional practice is not required, the trouble is saved and the cost can thus be reduced.

Abstract: PURPOSE:To fix a semiconductor element without bubbles to the adhesive surfaces between the semiconductor element and a metal layer by providing a groove in the metal layer. CONSTITUTION:A metal layer 3a is provided on all the area of the cavity 2a on an insulating ceramic substrate 1a and a semiconductor element is mounted on a semiconductor element mounting region 4a which is part of the metal layer 3a. A plurality of grooves 9a are provided on the metal layer 3a in the direction of the width of the semiconductor element mounting region 4a in parallel. The length of the groove 9a is longer than the width of the semiconductor element mounting region 4a and when the semiconductor element is fixed on the metal layer 3a, the end of the groove 9a is opened. This makes the bubbles interposed between the semiconductor element and the metal layer 3a escape externally through the groove 9a and the region except the groove and the semiconductor element are perfectly stuck. The metal layer 3a is not electrically cut since the length of the groove 9a is made shorter than the width of the metal layer 3a and the surface of the metal layer 3a can be electrolytically plated with nickel or gold on all the area.
